A dilation is a transformation that changes the size of an object by a scale factor. To dilate a triangle by a scale factor of 2/3, you will need to follow these steps:
Identify the center of dilation: The center of dilation is a fixed point around which the dilation takes place. This point is usually denoted by the letter "C".Identify the vertices of the triangle: The vertices of the triangle are the points that determine the shape and position of the triangle.Calculate the new coordinates of the vertices: To dilate a triangle by a scale factor of 2/3, you need to multiply the coordinates of each vertex by the scale factor. For example, if the coordinates of a vertex are (x, y), the new coordinates will be (2/3x, 2/3y).Plot the new coordinates: Once you have calculated the new coordinates of the vertices, you can plot them on the coordinate plane to create the dilated triangle.Connect the new points to form the new triangle: Connect the new points with lines to form the new triangleNote that the center of dilation C and the dilation factor are the same for all points on the triangle, also if the dilation factor is less than 1, the image is smaller than the original and if the dilation factor is greater than 1, the image is larger than the original.

what is the measure of the largest side of an isosceles acute, if one side is 36
The measure of the largest side of an isosceles acute triangle with one side of 36 degrees is 72 degrees.
What is an isosceles triangle?A triangle with two sides and angles of equal length and degrees is an isosceles triangle.
Acute Triangle:-
A triangle whose all angels are greater than and less than 90° i.e., all angels are acute is called an acute triangle.
Therefore, all the three angles are less than 90 degrees and two angles are equal.
If one angle is 36 degrees, the other two angles will be 72 degrees each.
If the two angles are 36 degrees each, the last angle will be 108 degrees. 108 degrees is greater than 90 degrees..
Therefore, the angles will be 36°, 36° and 72°.
Hence, the measure of the largest side of an isosceles acute triangle with one side of 36 degrees is 72 degrees.

A farmer claims that the average mass of an apple grown in his orchard is 100g. To test this claim, he measures the mass of 150 apples that are grown in his orchard and determines the average mass per apple to be 98g. The results are calculated to be statistically significant at the 0.01 level. What is the correct interpretation of this calculation
The data is significant at a significance level of 0.01 indicating that the average mass of apples in a farmer's orchard differs from 100g to a level of 0.01. Option C is correct.
Given as the farmer states that the average mass of an apple grown in his orchard is 100g, he measures the mass of 150 apples grown in his orchard and finds that the average mass per apple is 98g and the results are calculated as statistically significant at the 0.01 level.
The null hypothesis is:
H₀ = 100
Because of the farmer's claim.
The alternative hypothesis is:
H₁ ≠ 100
The alternative hypothesis tests the farmer's claim at a level of significance. Results are calculated as statistically significant at the 0.01 level.
This means that at the 0.01 level, the null hypothesis is rejected, i.e. H the average mass of the farmer's orchard differs from 100. Since it is significant at the 0.01 level, it will be significant at the 0.05, 0.1 and increasing levels.
Thus, at the significance level of 0.01, the average mass of apples grown in the farmer's orchard differs by 100 g. The correct answer is therefore given by option C.

Consider the given set of numbers 70, 81, 91, 83, 88, and 55. A new number equal to a 12% increase in the median of this set is added to the list. What percentage larger is the mean of the new list in comparison with the original
New mean is 2.53% larger than the original mean.
What is mean?
Mean is nothing but the average of the given set of values. It denotes the equal distribution of values for a given data set.
We can find the percentage larger is the mean of the new list in comparison with the original as shown below:
Given, set of number 55, 70, 81, 83, 88, 91
Median= (81+83)/2
= 164/2
= 82
Mean = (55+70+81+83+88+91)/6
= 468/6
= 78
New value which is added = 82*1.12
= 91.84
New Mean = (55+70+81+83+88+91+91.84)/7
= 559.84/7
= 79.97
Increase in mean = 79.97-78
=1.97
increase percentage (1.97/78) *100
= 2.53%
Hence, new mean is 2.53% larger than the original mean.

Luiza wants to go on a popular talent TV show. In order to be accepted, her audition must get at least 60%
positive votes from the people in the crowd. She was afraid she will not get enough votes, so she made a
video of her act and showed it to 60 random people from the crowd before the show. 50% of the people
said they would vote for her.
Let's test the hypothesis that the actual percentage of positive votes among the crowd is 60% versus the
alternative that the actual percentage is lower than that.
The table below sums up the results of 1000 simulations, each simulating a sample of 60 votes, assuming
there are 60% positive votes.
According to the simulations, what is the probability of getting a sample with 50% positive votes or less?
Let's agree that if the observed outcome has a probability less than 1% under the tested hypothesis, we
will reject the hypothesis.
What should we conclude regarding the hypothesis?
Choose 1 answer:
We cannot reject the hypothesis.
We should reject the hypothesis.
We cannot reject the null hypothesis as the p value is less than 0.01.

Suppose the daily customer volume at a call center has a normal distribution with mean 4,900 and standard deviation 700. What is the probability that the call center will get fewer than 4,400 calls in a day
The probability that the call center will get fewer calls than 440 is 0.26115.
Given mean of 4900 and standard deviation of 700.
We have to calculate the probability that the call center will get fewer than 4400 calls.
Probability lies between 0 and 1.
μ=4900
σ=700
We can apply z as well as t statistics because the sample size is not given.
We are applying z statistics.
P(X<4400)=0.5-P(4400<X<4900)
z=X-μ/σ
where μ= mean
σ=standard deviation
z=4400-4900/700
=-500/700
=-0.71
p value of -0.71 is 0.23885.
So the p value of calls less than 4400 is 0.5-0.23885=0.26115.
Hence the probability that the call center will get calls less than 440 is 0.26115.

Suppose there is a triangle with sides a, b, and c and angles A, B, and C. Using the known given information below and the law of cosines, what is the measure of angle C? Round your answer to the nearest whole number, if necessary.
A=29
C=24
B=101
The measure of angle C is obtained as 35 degrees
What is the angle C?Give that;
b^2 = a^2 + c^2 - 2ac Cos B
a = 29
c = 24
B = 101 degrees
b^2 = (29)^2 + (24)^2 - [2 * 29 * 24 cos 101]
b^2 = 841 + 576 + 266
b = 41 cm
Now;
b/sinB = c/sinC
bsinC = csinB

Variable m cannot be equal to any of the values −2,4 as division by zero is undefined. Multiply both sides of the equation by (m − 4)(m + 2), the lowest common denominator of 4−m,m + 2.
−(2 + m) ×5 = (m −4 )( −3 )To find the opposite of 2+m, find the opposite of each term.
(−2 −m) ×5 = ( m−4 )( −3 )Use the distributive property to multiply −2−m by 5.
−10 −5m = ( m−4 )( −3 )Use the distributive property to multiply m−4 by −3.
−10 −5m =−3m + 12Add 3m to both sides.
−10 − 5m + 3m =12Combine −5m and 3m to get −2m.
−10 −2m = 12Add 10 to both sides.
−2m = 12 + 10Add 12 and 10 to get 2.
−2m = 22Divide both sides by −2.
m = 22 / -2Divide 22 by −2 to get −11.
m = −11Therefore, the correct option is "B".
