Answer:
8 white shirts22 colored shirtsStep-by-step explanation:
Let c represent the number of colored shirts sold. Then c-14 is the number of white shirts sold. The total revenue is ...
10.50c +9.95(c -14) = 310.60
20.45c -139.30 = 310.60 . . . . . . simplify
20.45c = 449.90 . . . . . . . . . . add 139.30
c = 22 . . . . . . . . . . . . . . . . . divide by 20.45
c-14 = 8
22 colored shirts and 8 white shirts were sold.

According to the admissions director of a certain college, approximately 11% of the 250 freshmen admitted had
applied using the early decision option. Suppose that we took random samples of 20 freshmen from this
population and computed the proportion of freshmen in each sample who had applied using the early decision
option. We can assume the admissions director's claim is true.
What will be the shape of the sampling distribution of p?
Answer:
Skewed to the right
Step-by-step explanation:
We have a right-skewed sampling distribution because the population proportion is so extreme relative to the sample size that there are fewer than 10 expected successes per sample.
The shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample.
What is a histogram?It is defined as the numerical data representation in the graph with the help of a bar without space. The histogram gives an idea about the data's approximate distribution.
We have:
11% of the 250 freshmen admitted had applied using the early decision option.
Total number of samples = 20
It is given that the admissions director's claim is true.
As we can see from the data shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample since the population proportion is so excessive in comparison to the sample size.
Thus, the shape of the sampling distribution of p is skewed to the right because there are fewer than 10 projected successes per sample.

Which equation has a solution of 4? Select all that apply. A 12x = 3 C10 + x = 14 B 6x = 24 DX-4 = 8
Answer:
C and B
Step-by-step explanation:
A. 12x = 3, x =1/4
C. 10 + x = 14, x = 4
B. 6x = 24, x =4
D. x -4 = 8, x =12
Only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
A
12x = 3
Simplifying the above expression,
12x = 3
x = 3 / 12
x = 1 / 4
Similarly simplifying all the expressions gives,
B. x = 4
C. x = 4
D. x = 12
Thus, only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.

There would be 58 1/3 campers at the camp.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that camp orders 200 badges. The plan to give 25 badges to counselors and ordered at least 3 badges for each camper.
Therefore, the difference would be;
200-25= 175
Then we get;
175÷3= 58 1/3
Hence, There are 58 1/3 campers

Why do you think we need to convert normal distribution to standard normal distribution?
Answer:
The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions

-55 5/10000
Step-by-step explanation:
We can break each word down. Negative would be the negative sign (-), fifty-five would be 55, and five ten-thousandths would be 5/10000. If we put them together, we would get -55 5/10000, which is the answer.
Why is stock data calculated using the subtraction and addition method instead of a simple moving average? PLEASE HURRY I AM TAKING A TEST
Answer:
The moving average (MA) is a simple technical analysis tool that smooths out price data by creating a constantly updated average price. The average is taken over a specific period of time, like 10 days, 20 minutes, 30 weeks or any time period the trader chooses. There are advantages to using a moving average in your trading, as well as options on what type of moving average to use. Moving average strategies are also popular and can be tailored to any time frame, suiting both long-term investors and short-term traders.
Step-by-step explanation:
One disadvantage to solving systems using substitution is that isolating a variable often involves dealing with messy fractions. There is another method for solving systems of equations: the addition/subtraction method.
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. In order for the new equation to have only one variable, the other variable must cancel out. In other words, we must first perform operations on each equation until one term has an equal and opposite coefficient as the corresponding term in the other equation.

Answer:
5 out of 25
Step-by-step explanation:
The amount of apple fritters is 2 out of ten orders. 2/10 simplifies to 1/5. If u put 1/5 next to x/25 on a piece of paper, u can see that 5 times 5 will give u 25. This means that u should also multiply 1 times five to find the value of x. 1x5=5. So, 5 out of 25 pastries should be apple fritters. Hope this is right, let me know!

A triangle has a base of 10 inches and a height of 4.5 inches. What is the area of the triangle in square inches?
Answer:
22.5
Step-by-step explanation:
10 x 4.5 = 45 divided by 2 is 22.5
Answer:
22.5inch²
Step-by-step explanation:
area of a triangle = 1/2 base × height
base = 10 inches, height = 4.5inches
area = 1/2× 10 × 4.5
area = 5×4.5
area = 22.5inch²
