Given triangle XYZ with ZX = 30°, ZY= 20° and ZZ = 2aº, what is the value of a?
A. 130
B. 65
C. 40
D. 20
According to the question, we are given a triangle XYZ
where,
∠X = 30° ∠Y = 20° ∠Z = 2a°Angle sum property states that sum of all the angles of triangle is 180°. So by adding all the three angles we will get the required value of a.
∠X + ∠Y + ∠Z = 180°
30° + 20° + 2a° = 180°
50° + 2a° = 180°
2a° = 180° - 50°
2a° = 130°
a° = 130/2
a° = 65°
Therefore, required value of a is 65°
Answer:
B
Step-by-step explanation:
remember : the sum of all angles in a triangle is always 180°.
are you sure the third angle is called ZZ ?
I am rather sure it would be called XY !
so,
180 = ZX + ZY + XY = 30 + 20 + 2a
130 = 2a
a = 130/2 = 65°
if 80% of people can read and you have a sample size of 11 people. how many people would you need to interview to be 87% sure that 7 of the 11 people could read
There are 11 people in your sample size and 80% of them can read.
To be 87% sure that 7 of the 11 people could read, you would need to interview eight people.
To calculate this, you need to use a binomial probability formula.
This formula will allow you to calculate the number of successes (people who can read) that must be achieved in order to have an 87% certainty that the sample size of 11 people is representative of the population.
The formula you need to use is P(x) = n! / (x! (n - x)!).
You'll want to plug in x = 7, n = 8. This will give you the probability of 8 successes in 8 trials, which is equal to 0.87. Therefore, you will need to interview 8 people in order to be 87% sure that 7 of the 11 people could read.

the gnollish language consists of $3$ words, ``splargh,'' ``glumph,'' and ``amr.'' in a sentence, ``splargh'' cannot come directly before ``glumph''; all other sentences are grammatically correct (including sentences with repeated words). how many valid $3$-word sentences are there in gnollish?
There are $22$ valid $3$-word sentences in gnollish.
We can count the number of valid sentences by counting the number of all possible 3-word sentences and subtracting the number of invalid sentences where "splargh'' comes directly before "glumph.''
The total number of possible 3-word sentences is 3³ = 27, as there are 3 choices for each word.
To count the number of invalid sentences where splargh'' comes before glumph,'' we can fix splargh'' in the first position and then there are only 2 choices for the second position and 2 choices for the third position (since we cannot use splargh'' or glumph'' again). Thus, there are 2 * 2 = 4 invalid sentences where splargh'' comes before ``glumph.''
Therefore, the number of valid sentences is 27 - 4 = 23. However, we must also exclude the sentence where all three words are the same (i.e., ``splargh splargh splargh''), since this sentence is not valid according to the given condition. Thus, the final answer is 23 - 1 = 22.

the sampling distribution becomes approximately normal, for all statistics, if there is a large enough sample size. a. false b. true
The given statement "the sampling distribution becomes approximately normal, for all statistics, if there is a large enough sample size" is True as it is proved by the central limit theorem.
The central limit theorem (CLT) states that for large enough sample sizes, the distribution of the sample means approximates a normal distribution regardless of the shape of the initial population distribution.
It is a statistical theory that clarifies how the mean of a random sample of independent observations drawn from a non-normal population converges in distribution to a normal population.
According to this theory, the sample size should be at least 30 for the sample mean to have an approximately normal distribution. The following are the fundamental assumptions of the central limit theorem:
A large enough sample size is requiredPopulation must be random and independentThe variance of the population must be finiteThe sampling must be done with replacement.Therefore, we can say that the sampling distribution becomes approximately normal, for all statistics, if there is a large enough sample size.

What is linear function ?
A linear function is a mathematical function that can be represented by a straight line on a graph. It has the form of:
y = mx + b
where m is the slope of the line, which determines how steeply the line rises or falls, and b is the y-intercept, which is the point where the line crosses the y-axis.
According to the question:
If Daisy calls in sick, then Lisa will be the only stylist at the salon, and all customers will go to her. Let's use x to represent the number of Lisa's customers. Then the income generated by Lisa's customers can be represented by the equation:
18x = projected income
We can solve for x by dividing both sides of the equation by 18:
x = projected income / 18
Substituting the given projected income of $216, we get:
x = 216 / 18 = 12
Therefore, Lisa would need to serve 12 customers to attain the projected income if Daisy calls in sick that day.

the difference between a two digits number and its two digits reverse is 72. how many numbers of this type exist?
The two numbers that fit the description are 27 and 99.
There are two numbers that fit this description. To find them, we can solve the equation:
Difference = Number - Number’s Reverse
Difference = 72
Number - Reverse = 72
Let’s call the two-digit number “x” and its reverse “y”. So, we can rewrite the equation as:
x - y = 72
Now, we can solve the equation using algebraic methods. First, add “y” to both sides of the equation:
x - y + y = 72 + y
x = 72 + y
Next, let’s solve for “y” by subtracting “72” from both sides of the equation:
x - 72 = 72 + y - 72
x - 72 = y
Therefore, we can rewrite the equation as:
x - 72 = y
Now, we can solve for “x” and “y” by plugging in possible values for “x” and “y” and seeing which ones work. Since we’re dealing with two-digit numbers, let’s start with numbers between 10 and 99.
First, let’s try x = 10 and y = 82.
10 - 82 = -72
This doesn’t work, since the difference cannot be negative.
Next, let’s try x = 15 and y = 87.
15 - 87 = -72
Again, this doesn’t work.
Finally, let’s try x = 27 and y = 99.
27 - 99 = -72
This works! So, the two numbers that fit the description are 27 and 99.

Even though the table appears to have varied shapes depending on the angle from which it is seen, Baby Mary recognizes the table as having the same shape. Shape constancy can be seen in this situation.
What is Shape Constancy?Shape constancy is the ability of an object to retain its shape, size, and orientation even when viewed from different perspectives or angles. In essence, when the shape of an object is known, this allows an individual to recognize the object as a whole.
It's an important part of perception, and it's what allows us to recognize objects even when they're partially obscured or viewed from a different angle. A child can recognize objects as having the same shape, regardless of the angle from which they are viewed. As the object is observed from a variety of angles, its proportions and the shapes of its edges and sides change. Even so, the child perceives the object as having a consistent shape, size, and orientation.
This can be attributed to the ability of a child's brain to maintain a mental image of the object's actual shape, even when presented with an altered image.
As a result, a child may perceive an object as having a consistent shape, even if it appears to be different from one angle to another.

The height οf the juice can is apprοximately 9.98 inches.
What is cylinder?A cylinder is a three-dimensiοnal geοmetric shape that cοnsists οf twο cοngruent and parallel circular bases, and a curved lateral surface that cοnnects the twο bases. The twο bases are usually circular, but they can be any οther shape as well. The lateral surface οf a cylinder is curved, and it has the same crοss-sectiοn alοng its entire length.
The volume of a cylinder is given by the formula [tex]\rm V = \pi r^{2}h[/tex], where V is the volume, r is the radius, and h is the height.
Since the diameter of the juice can is 4 inches, the radius is half of that, or 2 inches.
We are given that the volume of the can is 125 cubic inches, so we can set up the equation:
[tex]\rm 125 = \pi (2)^{2}h[/tex]
Simplifying this equation, we get:
125 = 4πh
Dividing both sides by 4π, we get:
h = 125 / (4π)

Based on the given circle with center Y and line AD is perpendicular to line DB, we can reasonably infer and logically deduce that arc AC is equal to arc BC;
mAC = mBC = 71 degrees.
mAB = mAC + mBC
mAB = 71 + 71
mAB = 142 degrees.
Since line DC is the perpendicular bisector of line AB, the measure of line AB and line BD can calculated as follows;
AD = BD = AB/2
AD = BD = 60/2
AD = BD = 30 units.
Note: YB is the radius of this circle and the hypotenuse of right-angle triangle YDB, which is equal to 34 units.
In order to determine the length of YD, we would have to apply Pythagorean's theorem as follows;
x² + y² = z²
BD² + YD² = YB²
30² + YD² = 34²
YD² = 1156 - 900

When the polynomial p(x)=-x^5-2x^3+4x-3, then the value of p(-1) is 3
The Remainder Theorem is a fundamental concept in algebra that relates the value of a polynomial at a certain point to the remainder of the polynomial's division by a linear factor.
The remainder theorem states that when a polynomial p(x) is divided by (x - a), the remainder is equal to p(a).
In this case, we are asked to find p(-1) when p(x) = -x^5 - 2x^3 + 4x - 3.
To use the remainder theorem, we need to divide p(x) by (x - (-1)), which is the same as (x + 1).
We can perform polynomial long division to find the quotient and remainder
The remainder is -x + 2, which means that p(-1) = -(-1) + 2 = 3.

Given that the water is being drained from a container which has the shape of a right circular cone. The cone has a radius of 3 inches at the top and a height of 6 inches. When the water is 3 inches deep, the surface level is falling at a rate of 2 inches per second. We need to find the rate at which the water is being drained from the container.
Step 1: Calculate the volume of the cone. Consider the cone with the height h = 6 inches and radius of the base r = 3 inches. Let H be the height of the water and V be the volume of the water in the cone. Let V0 be the volume of the cone.
Cone Volume formula: $V=\frac{πr^{2}h}{3}$V0 = πr²h/3 = (3.14) (3²) (6)/3 = 56.52 cubic inches
Step 2: Find the rate at which the water level is falling. Let the rate at which the water level is falling be dh/dt. When the water is 3 inches deep, the surface level is falling at a rate of 2 inches per second. Thus, dh/dt = -2.
Step 3: Find the rate at which the water is being drained from the containerLet dv/dt be the rate at which the water is being drained from the container. To find this rate we need to differentiate the volume of water with respect to time V = (1/3)πr²H.H²dv/dt = (2/3)πr² dh/dtdv/dt = (2/3)π(3²)(-2) = -12.56 cubic inches per second.
Hence, the rate at which the water is being drained from the container is -12.56 cubic inches per second.

Choose any x value, let's say x=0, and find the corresponding y value by substituting it into the equation: y=5(0) = 0. This gives us the point (0,0).
Choose another x value, let's say x=1, and find the corresponding y value: y=5(1) = 5. This gives us the point (1,5).
Therefore, A steep slope of 5 means that the line for y=5x climbs 5 units for every 1 unit to the right and passes through the origin (0,0). The line for [tex]y=4x-1[/tex] has a slope of 4, which means it rises 4 units for every 1 unit to the right, and it meets the y-axis at -1.
