Answer:
0.13188 km
Step-by-step explanation:
The distance covered by the bicycle wheel can be calculated using the formula:
distance = circumference x number of revolutions
The circumference of the wheel can be calculated using the formula:
circumference = 2 x pi x radius
where pi is approximately equal to 3.14.
Substituting the given values:
circumference = 2 x 3.14 x 30 cm
circumference = 188.4 cm
Now, we can calculate the distance covered by the wheel:
distance = circumference x number of revolutions
distance = 188.4 cm x 70
distance = 13188 cm
To convert this distance from centimeters to kilometers, we need to divide by 100,000 (since there are 100,000 centimeters in a kilometer):
distance = 13188 cm ÷ 100,000
distance = 0.13188 km
Therefore, the distance covered by the bicycle wheel is approximately 0.13188 km.
The distribution of the number of occurrences of the letter t on the pages of a book is found to be a normal distribution with a mean of 44 and a standard deviation of 18. If there are 500 pages in the book, which sentence most closely summarizes the data?
Answer:
The letter t occurs more than 26 times on approximately 420 of these pages.
Step-by-step explanation:
1 standard deviation below mean = M - SD
= 44 - 18 = 26
This implies that that "26" is 1 s.d. below the mean, which is at the 16th percentile.
Thus, there is a 0.16 chance that "t" will occur less than 26 times on any single page.
consequently, there is a 0.84 chance that it will occur more than 26 times on any single page.
If I have a jug with 30 mL of cordial mixed into 300 mL of water, what is the fraction of water in the jug?
Ines's younger brother will be home in a half hour. If her garden hose flows at a rate 24 gal/min, does she have enough time to fill the pool before he gets home? Explain.
Since the volume of the pool is 948.98 gallons gallons and the garden hose can fill 720 gallons in half an hour, it is clear that Ines cannot fill the pool completely before her brother gets home in half an hour.
To determine if Ines has enough time to fill the pool before her brother gets home, we need to calculate the volume of the pool and the amount of water that the garden hose can fill in the given time.
The pool is cylindrical with an outer diameter of 9 ft and a height of 3 ft, which means the radius of the pool is 4.5 ft (half the diameter).
The width of the pool is given as 10 inches, which is 10/12 = 0.83 ft
radius of inner pool = 4.5-0.83 = 3.67 ft
The volume of the pool can be calculated using the formula for the volume of a cylinder:
[tex]V_{pool} = \pi r^2h[/tex]
where π is approximately 3.14, r is the radius, and h is the height.
Substituting the given values, we get:
[tex]V_{pool} = 3.14 * (3.67)^2 * 3[/tex]
[tex]V_{pool} = 126.87 ft^3[/tex]
To convert this volume to gallons, we need to multiply by the conversion factor of 7.48 gallons per cubic foot:
[tex]V_{pool} = 126.87 * 7.48[/tex]
[tex]V_{pool }= 948.98 gallons[/tex]
Now we need to determine how much water the garden hose can fill in half an hour, which is 0.5 hours.
The flow rate of the garden hose is given as 24 gallons per minute, so in half an hour it can fill:
24 gallons/min * 30 min = 720 gallons
Since the volume of the pool is 948.98 gallons gallons and the garden hose can fill 720 gallons in half an hour, it is clear that Ines cannot fill the pool completely before her brother gets home in half an hour.

which of the following true of correlations? group of answer choices a correlation is when two events occur together at a rate higher than mere chance would predict. a correlation always indicates a causal relationship. a positive correlation holds when the occurrence of one event decreases the chance of another event occurring. none of these answers are correct.
Group of answer choices a correlation is when two events occur together at a rate higher than mere chance would predict.Therefore, none of these answers are correct.
The following is true of correlations: A correlation is when two events occur together at a rate higher than mere chance would predict. This is because when two events occur together, they are likely related to one another, rather than it being coincidental. However, correlation does not always indicate a causal relationship. Correlation is just an association between two variables, which could be because of chance, or there could be another variable that causes the two events to occur together.
A positive correlation holds when the occurrence of one event increases the chance of another event occurring. This means that when one variable increases, the other also increases. A negative correlation holds when the occurrence of one event decreases the chance of another event occurring. This means that when one variable increases, the other decreases.

A vector has a magnitude of 30 and a direction of 40°. Another vector has a magnitude of 70 and a direction of 130°. What are the magnitude and direction of the resultant vector? Round the magnitude to the thousandths place and the direction to the nearest degree.
69.504; 73°
76.158; 73°
69.504; 107°
76.158; 107°
The magnitude and direction of the resultant vector are 76.158 and 100.496° (rounded to the nearest degree).
So the answer is 76.158; 100°.
To find the magnitude and direction of the resultant vector, we can use the vector addition formula:
R = sqrt(A^2 + B^2 + 2ABcosθ)
Where R is the magnitude of the resultant vector, A and B are the magnitudes of the two vectors, and θ is the angle between them.
First, we can convert the given angles to radians by multiplying by π/180:
40° * π/180 = 0.698 radians
130° * π/180 = 2.268 radians
Then we can plug in the given values and solve for the magnitude of the resultant vector:
R = sqrt(30^2 + 70^2 + 2(30)(70)cos(2.268 - 0.698))
R = 76.158 (rounded to the thousandths place)
Next, we can use the law of cosines to find the angle between the resultant vector and the 30-magnitude vector:
cosθ = (R^2 + A^2 - B^2) / 2RA
cosθ = (76.158^2 + 30^2 - 70^2) / (2 * 76.158 * 30)
cosθ = 0.499
θ = cos^-1(0.499)
θ = 60.496°
Since this angle is between the 30-magnitude vector and the x-axis, we need to add 40° to get the angle between the resultant vector and the x-axis:
60.496° + 40° = 100.496°

what does a filled-in symbol in a pedigree indicate?
Answer:
In a pedigree chart, a filled-in symbol (usually a circle or square) typically indicates that the individual represented by that symbol has the trait or condition of interest. This trait or condition may be a genetic disorder or a physical characteristic that is being studied.
For example, in a pedigree for a genetic disorder such as Huntington's disease, a filled-in circle or square would indicate an affected individual who has inherited the disease-causing allele from one or both parents. In contrast, an unfilled symbol would indicate an individual who does not have the disease or does not carry the disease-causing allele.
Overall, the use of filled-in symbols in a pedigree chart helps to visually represent the inheritance pattern of a trait or condition within a family.

which of these comparisons between an anova and a t test is correct? a. a t test provides more flexibility in research studies than an anova. b. a t test can be used to compare two conditions, whereas an anova cannot. c. an anova examines whether mean differences exist between conditions, whereas a t test does not. d. an anova can be used to compare three or more conditions, whereas a t test cannot.
Option C. An ANOVA examines whether mean differences exist between conditions, whereas a t-test does not is the correct comparison between an ANOVA and a t-test.
What is ANOVA?
ANOVA (Analysis of Variance) is a statistical method that helps to compare three or more means or groups. It is used in behavioral and social sciences research, which determines whether the mean of the dependent variable is significantly different across different levels of an independent variable.
It is used for statistical inference in comparing the means of two or more groups. ANOVA is based on the idea of variance; that is, the variation between the groups' means is compared to the variation within the groups. By assessing the significance of the difference between group means, ANOVA determines whether there is sufficient evidence to conclude that they are not all equal.
What is a t-test?
A t-test is a statistical hypothesis test that compares the means of two independent groups. It is used when the data in each of the groups being compared is normally distributed. The t-test is a parametric test that compares the means of two groups and calculates the standard error of the difference between the means. It compares the difference between the two groups to the variability within each of the groups. The difference between the sample means is examined relative to the variability between the groups. The t-test produces a test statistic that can be compared to a critical value to determine if the means of the two groups differ significantly. It is commonly used to examine if the means of two independent groups are significantly different.
The primary differences between t-test and ANOVA are in terms of the number of groups, and that ANOVA is used for testing the significance of differences between more than two groups while t-tests are used for testing differences between two groups. Hence, ANOVA is used when we want to compare three or more groups, while t-tests are used when we want to compare two groups. Option C. An ANOVA examines whether mean differences exist between conditions, whereas a t-test does not is the correct comparison between an ANOVA and a t-test.

The rate at which the shadow of the man is increasing in length is 1/5 m/s.
We can solve this problem using similar triangles. Let x be the length of the shadow, and let y be the distance between the man and the base of the lamppost. Then, we have the following equation:
(1.4 + x)/y = 1/5
Solving for x, we get:
x = (y/5) - 1.4
Differentiating both sides with respect to time t, we get:
dx/dt = (1/5) dy/dt
We are given that dy/dt = 1 m/s, so substituting that in, we get:

The value of b that makes the expression 9(a+5) and 9(b+a) equivalent is 5.
To make the expression 9(a+5) and 9(b+a) equivalent, we need to find the value of b that makes them equal for all values of a.
We can start by expanding expressions using distributive property of multiplication:
9(a+5) = 9a + 45
9(b+a) = 9b + 9a
Two expressions will be equal if 9a + 45 = 9b + 9a for all values of a.
Simplify this equation by subtracting 9a from LHS and RHS:
45 = 9b
Finally, divide by 9 by b:
b = 5
To make the expressions equivalent, we need to find the value of b that makes 9(a+5) equal to 9(b+a) for all values of a. We can do this by expanding both expressions and equating them, and then solving for b. The value of b that we get is 5, which means that we can rewrite 9(a+5) as 9(5+a) to make it equivalent to 9(b+a).

Two bakers make 30 loaves of bread every morning. Assume all bakers work at the same rate. Suppose two bakers make 30 loaves in one hour. How many hours would 3, 5, 6, and 15 bakers need to make 30 loaves?
Step-by-step explanation:
2 bakers make 30 loaves in 1 hour.
that means each baker just by him-/herself can make 15 loaves in 1 hour.
so,
1 baker's "speed" = 15 loaves/hr
15 l/h = 30l/x
x = 30/15 = 2 hours (1 baker takes 2 hours to make 30).
3 bakers' speed = 3×15/hr = 45l/h
45l/h = 30l/x
x = 30/45 = 2/3 hours (3 bakers need 2/3 hours = 40 minutes to make 30 loaves).
5 bakers = 5×15l/h = 75 l/h.
75l/h = 30l/x
x = 30/75 = 2/5 hours (5 bakers need 2/5 hours = 2×60/5 = 24 minutes to make 30 loaves).
6 bakers = 6×15l/h = 90 l/h.
90 l/h = 30/x
x = 30/90 = 1/3 hours (6 bakers need 1/3 hour = 60/3 = 20 minutes to make 30 loaves).
15 bakers = 15×15 l/h = 225 l/h
225 l/h = 30/x
x = 30/225 = 2/15 hours (15 bakers need 2/15 hours = 2×60/15 = 2×4 = 8 minutes to make 30 loaves).

p,q and r are points on a circle o .if OPQ =36,what is the size of PRO
The answer of the given question based on the finding the size of PRO is angle PRO = 180° degrees.
What is Circle?A circle is a closed two-dimensional shape that is formed by a set of points that are all equidistant from a single point called the center. The distance from the center to any point on the circle is called the radius of the circle. A circle can be defined as the locus of all points that are at a fixed distance from a given point in a plane.
Since P, Q, and R are points on a circle with center O, we know that the measure of angle POQ is equal to 360 degrees (the total angle measure of a circle).
Therefore, we have:
angle ∠POR + angle ∠ROQ + angle ∠OPQ = 360° degrees
Since angle ∠OPQ is given as 36° degrees, we can substitute this value in and simplify:
angle ∠POR + angle ∠ROQ + 36 = 360
angle ∠POR + angle ∠ROQ = 324
Now, we use the fact that angles formed by chords that intersect within a circle are equal.
Since PQ is a chord that intersects chord PR at point O, we know that angle ∠POR is equal to angle ∠OQP. Similarly, angle ∠ROQ is equal to angle ∠OPQ.
Substituting these equalities in, we have:
angle ∠OQP + angle ∠OPQ + angle ∠OPQ = 324
2(angle ∠OPQ) + angle ∠OQP = 324
But we also know that the sum of the angles in triangle OPQ is 180° degrees. Thus:
angle ∠OQP + angle ∠OPQ + angle ∠POQ = 180
angle ∠OQP + 36 + 180 = 180
angle OQP = 144° degrees
Therefore, the measure of angle ∠PRO is:
angle ∠PRO = angle ∠POR + angle ∠OQP
angle ∠PRO = angle ∠OQP + angle ∠POR
angle ∠PRO = 144 + 36
angle ∠PRO = 180° degrees

The answer of the given question based on the finding the size of PRO is angle PRO = 180°.
What is Circle?A circle is a closed, two-dimensional object made up of a collection of points that are all equally spaced apart from the center. The distance from any point on the circle to its center is known as the radius of the circle. The center of every point in a plane that is isolated from another point by a certain distance is referred to as a circle.
Since P, Q, and R are points on a circle with center O, we know that the measure of ∠POQ is equal to 360° (the total angle measure of a circle).
Therefore, we have:
∠POR + ∠ROQ + ∠OPQ = 360°
Since ∠OPQ is given as 36°, we can substitute this value in and simplify:
∠POR + ∠ROQ + 36 = 360°
∠POR + ∠ROQ = 324°
Now, we use the fact that angles formed by chords that intersect within a circle are equal.
Since PQ is a chord that intersects chord PR at point O, we know that ∠POR is equal to angle ∠OQP. Similarly, ∠ROQ is equal to ∠OPQ.
Substituting these equalities in, we have:
∠OQP + ∠OPQ + ∠OPQ = 324°
2(angle ∠OPQ) + ∠OQP = 324°
But we also know that the sum of the angles in triangle OPQ is 180° degrees. Thus:
∠OQP + ∠OPQ + ∠POQ = 180°
∠OQP + 36 + 180 = 180°
∠OQP = 144°
Therefore, the measure of ∠PRO is:
∠PRO = ∠POR + ∠OQP
∠PRO = ∠OQP + ∠POR
∠PRO = 144 + 36
∠PRO = 180°

the summit of mount everest is approximately 29,035 ft above sea level. what is the distance from the summit to the horizon, rounded to the nearest mile? assume that the distance from the earth's center to any point on earth's surface is 4,000 miles.
Distance from the summit of Mount Everest to the horizon, Rounded to the nearest mile, the distance from the summit of Mount Everest to the horizon is 210 miles.
What is the distance?Distance refers to the space between two points or the length of a line between them. It may also refer to a range, extent, or magnitude that separates one point from another. Distance may be a physical concept, such as the distance between two cities or the distance traveled by a moving object.
The distance between two points can be calculated using a number of mathematical techniques, including the Pythagorean theorem, the distance formula, and vector addition.
d = √(2Rh + h²)
where d is the distance to the horizon, R is the radius of the Earth (4000 miles), and h is the height of the observer (in this case, the height of the summit of Mount Everest, which is 29,030 feet).
We need to convert the (h) height of the summit to miles:
29,030 ft = 29,030/5280 miles ≈ 5.49 miles
Now we can plug in the values and solve for d:
d = √(2 × 4000 × 5.49 + 5.49^2) =209.64288 ≈ 210 miles
Therefore, the distance from the summit of Mount Everest to the horizon is approximately 210 miles when rounded to the nearest mile.
