The box plot above summarizes the resting heart rates, in beats per minute, of the members at a gym.
Which of the following could be the range of resting heart rates, in beats per minute ?
The range of resting heart rates is 70 beats per minute. Subtracting the lowest value from the highest value will give us the range.
What is range?It is a set of data which is the difference between the highest and lowest values.
The range of resting heart rates, in beats per minute, is calculated by subtracting the minimum value of the data set from the maximum value. In this case, the minimum value = 35
and the maximum value = 105,
so the range of resting heart rates = 105 - 35
= 70 beats per minute
The other answers cannot be the range of the resting heart rates because they are not calculated correctly.
The answer 16 beats per minute (105 - 89 = 16) is the difference between the maximum and the 90th percentile, and the answer 31 beats per minute (85 - 54 = 31) is the difference between the 85th percentile and the median.

The average rate of change of P between t = 3 and t = 5 is -18 people/hour.
A possible value of people in line at t = 6, given the average rate of change would be 50.
How to find the average rate of change ?To find the average rate of change of P between t = 3 and t = 5, we can use the formula:
Average rate of change = (P(5) - P(3)) / (5 - 3)
From the table, we know P(3) = 85 and P(5) = 49.
Average rate of change = (49 - 85) / (5 - 3) = (-36) / 2 = -18 people/hour
To find the possible number of people at t = 6, Let P(6) = x. First, we will find the average rate of change between t = 3 and t = 6:
(P(6) - P(3)) / (6 - 3) = (x - 85) / 3
This value must be negative. Now, we will find the average rate of change between t = 5 and t = 6:
(P(6) - P(5)) / (6 - 5) = (x - 49) / 1
This value must be positive. Since (x - 49) is positive, we know that x > 49. Now we need to find a value for x that also satisfies the condition that the average rate of change between t = 3 and t = 6 is negative. Since (x - 85) / 3 is negative, we know that x < 85.
So, a possible value for P(6) is between 49 and 85. For example, we could choose P(6) = 50, which satisfies both conditions.

The arc length of a semicircle with radius 'r' is equal to rπ or approximately 3.14r units.
What is an arc?
An arc is part of a circle's circumference. It is a segment of a curved line that is formed when a straight line intersects a circle or a curved shape. Arcs can be measured in length, angle, or radius, depending on the context.
To find the arc length of a semicircle, we need to know the radius of the circle and the angle subtended by the arc at the center of the circle.
Let's assume the radius of the semicircle is 'r'. Since it is a semicircle, the angle subtended by the arc at the center of the circle is 180 degrees or π radians.
The formula for arc length is given by:
arc length = radius x angle in radians
In this case, the angle is π radians and the radius is 'r'. Therefore, the arc length of the semicircle is:
arc length = r x π
We can leave the answer in terms of π or substitute the value of π to get a numerical answer. For example, if the radius of the semicircle is 4 units, the arc length will be:
arc length = 4 x π
arc length ≈ 12.57 units (using π ≈ 3.14)
Therefore, the arc length of a semicircle with radius 'r' is equal to rπ or approximately 3.14r units.

Answer: y = x + 6
Step-by-step explanation: "y = m x + b" is the format used to find the equation of a line on a graph.
Y and X remain the same in the equation, however you replace "m" with the value of the slope. In this problem, the slope is "1" because the rise is 1 and the run is 1, making it 1/1 or 1. Because the slope is "1", we do not need to include the number "1" in our equation.
Finally, "b" is the y-intercept (in other words, the place where the line crosses the y-axis). In this problem, the line crosses at "6"; therefore, 6 will replace b in the equation completing it.

The complete table that shows the proportional relationship is:
x y

How to find the proportional relationship?The ratio of the given y-value and x-value is calculated as:
y/x = 4/0.8 = 5
Thus, the ratio of the next terms must all be 5.
The second x coordinate is 3.2. Thus:
y/3.2 = 5
y = 3.2 * 5
y = 16
Difference of the first 2 x-values = 3.2 - 0.8 = 2.4
Thus, the third value of x will be:
3.2 + 2.4 = 5.6
Thus, the third y-coordinate = 5.6 * 5 = 28
Similarly, the fourth value of x will be:
5.6 + 2.4 = 8.0
Thus, the fourth y-coordinate = 8 * 5 = 40
The sixth value of x will be:

at an amusement park 25 people ride the cras every 30 mins and 20 people rid the spinning swings which one will have more rides how many more
Answer:
Spinning Swings
10 more riders
Step-by-step explanation:
To find which ride will have more riders each hour, we need to first convert an hour into minutes.
[tex]\text{1 hour = 60 minutes}[/tex]
Now we let's first find how many riders there will be in the race cars.
So there are 25 riders every 30 minutes.
in 60 minutes there will be:
[tex]25 \times 2 = 50 \ \text{Riders}[/tex]
Now for the spinning swings there are 20 riders every 20 minutes.
In 60 minutes there will be:
[tex]20 \times 3 = 60 \ \text{Riders}[/tex]
Therefore, the spinning swings will have more riders as [tex]60 > 50[/tex].
Now to find how many more riders there will be in the spinning swings.
We simply subtract the total number of riders of each ride from each other.
[tex]\text{Race Cars = 50}[/tex]
[tex]\text{Spinning Swings = 60}[/tex]
[tex]60 - 50 = 10[/tex]
There will be 10 more riders in the spinning cups than the race cars.

Omar recorded the number of hours he worked each week for a year. Below is a random sample that he took from
data.
13, 17, 9, 21
What is the standard deviation for the data?
Answer:
Approx. 4.47
Step-by-step explanation:
To calculate the standard deviation for the data, we need to follow these steps:
1. Calculate the mean (average) of the data:
mean = (13 + 17 + 9 + 21) / 4 = 15
2. Calculate the difference between each data point and the mean:
13 - 15 = -2
17 - 15 = 2
9 - 15 = -6
21 - 15 = 6
3. Square each difference:
(-2)^2 = 4
2^2 = 4
(-6)^2 = 36
6^2 = 36
4. Calculate the variance by taking the average of the squared differences:
variance = (4 + 4 + 36 + 36) / 4 = 20
5. Calculate the standard deviation by taking the square root of the variance:
standard deviation = sqrt(variance) = sqrt(20) ≈ 4.47
Therefore, the standard deviation for the data is approximately 4.47.

How much interest was earned during the third month of the 7th year?
The interest earned during the third month of the 7th year is $3,613.55.
What is interest rate?
The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.
Let PMT be the monthly payment, r be the monthly interest rate, and n be the total number of payments. Then:
FV = PMT × [(1 + r)n - 1]/r
In this case, we want to find PMT, given that FV = $900,000, r = 0.038/12, and n = 10 × 12 = 120:
[tex]$900,000 = PMT * {[(1 + 0.038/12)}^{120} - 1]/(0.038/12)[/tex]
Solving for PMT, we get:
PMT = $682.48
[tex]FV = $682.48 * [(1 + 0.038/12)^87 - 1]/(0.038/12)\\\\ = $89,324.47\\\\PV = $682.48 * [(1 + 0.038/12)^83 - 1]/(0.038/12) \\\\= $85,710.92[/tex]
The interest earned during the third month of the 7th year is:
$89,324.47 - $85,710.92 = $3,613.55
Therefore, the interest earned during the third month of the 7th year is $3,613.55.

What is curve?
In mathematics, a curve is a continuous and smooth (i.e., differentiable) mathematical object that represents a path or a trajectory. Curves can be defined in different ways, depending on the context in which they are used.
What is area of curve?
The area of a curve refers to the amount of space enclosed by a curve on a two-dimensional plane. Finding the area of a curve can be a challenging problem, especially when the curve is not a standard geometric shape such as a circle or rectangle.
According to given minformation:To find the area of the shaded region under the standard normal curve with z = 0.49, we need to use a standard normal distribution table or a calculator with a normal distribution function.
Using a standard normal distribution table, we find that the area to the left of z = 0.49 is 0.6864. This means that the area to the right of z = 0.49 is 1 - 0.6864 = 0.3136.
Since the normal curve is symmetric about the mean (z = 0), the area to the left of z = -0.49 is also 0.6864. Therefore, the area between z = -0.49 and z = 0.49 is:
0.6864 (area to the left of z = 0.49) + 0.3136 (area to the right of z = 0.49) = 1
So the area of the shaded region under the standard normal curve with z = 0.49 is 1.

[tex]=(CD)^2\\\\=(4)^2\\\\=16[/tex]
Area of the EDH triangular [tex]=\frac{1}{2} \times BC\times DH[/tex]
Substitute values in the above equation
[tex]=\frac{1}{2} \times 4\times 5\\\\=10[/tex]
Total area = 16 + 10
= 26
The shaded region is then calculated as follows:
CDEF square shaded region = 25% x 16
= 4
Total shaded area = 4
Finally, compute the shaded-to-unshaded area ratio in the figure:
Unshaded area = 26 - 4
= 22
Shaded to unshaded region ratio = 4 : 22
= 1 : 5.5
As a result, the shaded area to unshaded area ratio in the image is 1: 5.5.

Can someone please show me step by step how to answer this question.
now, if we take a looksie at the denominators on all sides, hmmm 2 and 3, so we can get an LCD of 6, so let's multiply both sides by 6 to do away with the denominators.
[tex]4-\cfrac{x-2}{2}=x+\cfrac{1-2x}{3}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{6}}{6\left( 4-\cfrac{x-2}{2} \right)~~ = ~~6\left( x+\cfrac{1-2x}{3} \right)} \\\\\\ 24-3(x-2)~~ = ~~6x+2(1-2x)\implies 24-3x+6~~ = ~~6x+2-4x \\\\\\ 30-3x=2x+2\implies 30=5x+2\implies 28=5x\implies \cfrac{28}{5}=x\implies 5\frac{3}{5}=x[/tex]
4: The radius of a cylinder is 3x-2 cm. The height of the cylinder is x + 3 cm. What is the
surface area of the cylinder? Use the formula A = 2²²² +2arh.
02 (3x²+10x-8)
O 27(12x² +7x-2)
O27(12x² - 2x+13)
O 27 (12x²-5x-2)
The surface area (A) of a cylinder is given by the formula A = 2πr² + 2πrh, where r is the radius of the cylinder and h is its height.
In this case, the radius of the cylinder is 3x - 2 cm, and its height is x + 3 cm. Substituting these values into the formula, we get:
A = 2π(3x - 2)² + 2π(3x - 2)(x + 3)
Simplifying this expression, we get:
A = 2π(9x² - 12x + 4) + 2π(3x² + 7x - 6)
A = 18πx² - 24πx + 8π + 6πx² + 14πx - 12π
A = 24πx² - 10πx - 12π
So the surface area of the cylinder is 24πx² - 10πx - 12π.

18. Find the 21st term if a₁ = 3/5 and
d = -1/3
(a) -6.07
(b) 11.67
Answer:
a
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n[/tex] a₁ + (n - 1)d
here a₁ = [tex]\frac{3}{5}[/tex] and d = - [tex]\frac{1}{3}[/tex] , then
a₂₁ = [tex]\frac{3}{5}[/tex] + (20 × - [tex]\frac{1}{3}[/tex] )
= [tex]\frac{3}{5}[/tex] - [tex]\frac{20}{3}[/tex]
= 0.6 - 6.67
= - 6.07 ( to 2 decimal places )

Given 2^a = 16 find the value of a.
Please explain thanks.
Step-by-step explanation:
[tex]2 {}^{a} = 16[/tex]
Since our variable is in the exponent, we take the logarithm of both sides in order to solve for a.
The log base is 2 In order to cancel out base 2,
[tex]a = log_{2}(16) [/tex]
[tex]a = 4[/tex]
Let p and q be prime numbers satisfying
p^3-pq^2=42024
Find the sum of the digits of the product pq.
The sum of the digits of the product p×q is 8
Define the prime numbers?A positive integer bigger than one that can be divided only by itself and by one is referred to as a prime number.
Given that: p³ - pq² = 42024
p (p² - q²) = 42024
Since factors, 42024 = 2³ x 3 x 17 x 103, and p and q are prime numbers, we can see that p must be 3, 17 or 103, We can try each case:
If p = 3 then we have:
3 (9 - q²) = 42024
q² = -13,999
This equation has no real solutions for q, so p cannot be 3.
If p = 17, then we have:
17 (289 - q²) = 42024
q² = -2183
This equation also has no real solutions for q, so p cannot be 17 either.
If p = 103, then we have:
103 (10609 - q²) = 42024
10609 - q² = 408
q² = 10201
q = 101
This equation also has a solution for q = 101, so p = 103
Product of pq = 103×101 = 10403
So, the sum of the digits of the product pq = 1+0+4+0+3 = 8
