The box has 18 glazed donut hole that Chad bought.
The percentage of glazed donut holes = 60%
The percentage of powdered sugar donut hole = (100 - 60) % = 40%
Let us consider the total number of donut hole in the box bought by Chad to be 'x'
Number of powdered sugar donut hole = 12
Hence, we can say that the number of powdered sugar donut hole in the box Chad bought is:
(40% of x) = 12
Therefore, x = (12 x 100) / 40 = 30
Since the total number of donut hole in the box = 30
The number of glazed donut hole = 30 - 12 = 18
Thus, the box that Chad bought had 18 glazed donut hole.

The correct statements regarding the diagram include all the statements except: △RWS ≅ △UWT by AAS.
Given the image attached below, let's analyze each of the options given to determine whether they are correct or not.
Statement 1 is correct because based on reflexive property, ST in ΔRST is congruent to ST in ΔUTS.
Statement 2 is also correct because ∠RWS is vertically opposite to ∠UWT, so they are vertical angles.
Statement 3 is also correct because ΔRWS and ΔUWT have two pairs of congruent angles (∠SRW ≅ ∠TUW and ∠RWS ≅ ∠UWT) and one pair of non-included congruent sides (SR ≅ TU).
Statement 4 is incorrect because ΔRST and ΔUST do not have a pair of included congruent angles to meet the SAS Congruence Criterion.
Statement 5 is correct because since ΔRWS ≅ ΔUWT, ∠WTU ≅ ∠WSR based on the CPCTC theorem.
Therefore, the correct statements regarding the diagram include all the statements except: △RWS ≅ △UWT by AAS.Learn more about congruence theorem on:

In a survey of 1800 people who owned a certain type of car, 1260 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
70%
Step-by-step explanation:
To find the percentage, we divide the number by the total.
The amount of people who said they'd buy it again is 1260, and the total is 1800.
1260/1800=0.7.
This means that 70% were satisfied with the car.
Answer:
70% you just take the amount of people that were satisfies divided by the overall amount of people. you'll get e decimal but just move the decimal place to get the percent.

When given an inverse variation, how do you find k?
Considering an inverse proportional relationship, you find k taking a point (x,y), and multiplying the values of x and y.
What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For an inverse relationship, the function is:
[tex]y = \frac{k}{x}[/tex].
Then:
k = xy.
Which means that to find k, you take a point (x,y), and multiply the values of x and y.

In this diagram, we have KN and LM as opposite sides. For any parallelogram, the opposite sides are parallel (as shown by the arrow markers) and they are congruent to each other. In other words, KN and LM are the same length.
This means KN = LM and we can solve for x like so
KN = LM
3x-11 = x+15
3x-x = 15+11
2x = 26

If the term of arthematic progression decrease in magnitude then common difference must be
We can say that if the term of arithmetic progression decrease in magnitude then the common difference must be negative.
An arithmetic progression is a sequence where every term is a sum of the previous term and a common difference.
If we suppose the first term of an arithmetic progression to be a, and the common difference to be d, then the arithmetic progression goes like this:
The first term, a₁ = a,
Second term, a₂ = a₁ + d = a + d,
Third term, a₃ = a₂ + d = a + 2d,
Fourth term, a₄ = a₃ + d = a + 3d, and it goes so on up to,
The n-th term, aₙ = aₙ₋₁ + d = a + (n - 1)d.
In the question, we are asked if the term of arithmetic progression decrease in magnitude then what can we say about the common difference.
As the magnitude of the term decreases, we can show that as:
The n-th term < The first term,
or, aₙ < a₁,
or, a + (n - 1)d < a,
or, a + (n - 1)d - a < a - a {Subtracting a from both sides},
or, (n - 1)d < 0.
Since, n > 1, (n - 1) > 0, thus we get the common difference, d < 0, that is, the common difference is negative.
Thus, we can say that if the term of arithmetic progression decrease in magnitude then the common difference must be negative.

Move the red distribution at the top so that it aligns with the blue distribution. Now look at the green distribution at the bottom. How would you best interpret the green (bottom) distribution?
A- The distribution of differences between the sample means of each group has a mean at or near zero making it likely the two groups are not statistically different.
B- The distribution of differences between the sample means of each group has a mean at or near 325 making it likely the two groups are not statistically different.
C- The distribution of differences between the sample means of each group has a mean at or near zero making it likely the two groups are statistically different.
D- The distribution of differences between the sample means of each group has a mean at or near 325 making it likely the two groups are statistically different.
Answer:
A- The distribution of differences between the sample means of each group has a mean at or near zero making it likely the two groups are not statistically different.
Step-by-step explanation:
The distribution of both the red and blue is identical although the skewness differs slightly. The distribution of the two groups is identical and their mean is near to zero. The distribution of observation of the group provides clear view that these two groups are not statistically different.

An economist is studying salaries for high technology companies and wants to test the claim that the average salary for high
tech employees is less than $70,000.
The economist selects a sample of 35 random employees from various high tech companies and records their salaries.
Based on past studies, the economist determines that the population standard deviation is $8,500.
The economist conducts a one-mean hypothesis test at the 5% significance level to test the claim that the average salary for
high tech employees is less than $70,000.
The setup for the null and alternative hypothesis is given as:
Hoμ = 70,000; Ha < 70,000, which is a left-tailed test.
The sample data for 35 salaries is shown in the dataset below.
Use Excel to test the claim that the average salary for high tech employees is less than $70,000, where a = 0.05. Calculate
the test statistic, z, and the p-value, rounding to three decimal places.
The decision would be to fail to reject the null hypothesis and conclude that there is insufficient evidence.
How to solve for the mean of the data setThe formula is fx/n
To get fx we have to sum all of the values of x = 2430161
The total number in the data set = 35
Mean = 2430161/35
= 69433.17
This test is a left tail test.
sd = 8500
We have to make the hypothesisH0: u = 70000
H1 : U < 70000
z0.05 = 1.645
The decision would be to reject if z < critical value
Z= (69433.17 - 70000)/(8500/√35)
= -0.395
P-value can be gotten from the z score = 0.348
Given that the p value is > 0.05, we would have to fail to reject the null. The conclusion would be that there is insufficient evidence to support claim.

Function g is defined as g(x) = k f(x). What is the value of k?
What is the value of k?
Answer: Pick an x value like x = 2
Note that f(2) = 1 and g(2) = 2. This shows we've doubled the f(x) value to get g(x). Therefore k = 2.
Or you could pick on x = 4 to see f(4) = 2 and g(4) = 4. The output of f(x) has been doubled as well.
It doesn't matter what x is since we'll have this doubling effect go on. I recommend picking x values where the points on the blue graph land perfectly on a grid location. Something like x = 5 seems a bit tricky.
