Answer:
is there something suggested?
The American College Testing Corporation has a test called the ACT that is used for admissions to college. The American College Testing Corporation reports that students who attend 2-year colleges in the Midwest United States have an average ACT score of 21.5, with a standard deviation of 3.17. The president of the Minneapolis Community College wonders if students who attend her college have a ACT scores that are significantly different from the ACT scores reported by the American College Teaching Corporation. The president would perform a ___________ test, and use a z-critical value of _____.
Answer:
Two tailed test
+/-1.96
Step-by-step explanation:
Following this claim, the president would have to perform a two tailed test. Since he wants to know if the Act scores of students in her school are significantly different from what is reported by the ACT corporation.
At a confidence level that is 95%, the level of significance is = 0.05. then the z critical value to be used would be +/- 1.96

What is the probability of the outcome being an A?
Answer:
The probability of the outcome being an A is 1/2.
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] probability of the outcome being an A, option D.
---------------------------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.
The spinner is divided into 8 regions, thus, there are 8 total outcomes.4 of those regions are A, so there are 4 desired outcomes.---------------------------------------------
The probability of the outcome being an A is:
[tex]p = \frac{4}{8} = \frac{1}{2}[/tex]
Thus:
[tex]\frac{1}{2}[/tex] probability of the outcome being an A, option D.

Solve the equation and check your solution.
3x − 6 = 4(2 − 3x) − 8x
Answer:
x = 14/23
Step-by-step explanation:
3x − 6 = 4(2 − 3x) − 8x
3x − 6 = 8-12x − 8x
3x=14-20x
23x=14
x= 14/23
3(14/23)-6=4(2 − 3(14/23) − 8(14/23)
And solve hope this helps. Remember to isolate the variable when finding x for next time.
The solution to the given equation is x = 14/23.
To solve the equation 3x - 6 = 4(2 - 3x) - 8x, we will simplify and solve for x:
First, let's distribute 4 to the terms inside the parentheses on the right side of the equation:
3x - 6 = 8 - 12x - 8x
Next, let's combine like terms on the right side of the equation:
3x - 6 = -20x + 8
Now, let's bring all the x terms to one side of the equation by adding 20x to both sides:
3x + 20x - 6 = -20x + 20x + 8
This simplifies to:
23x - 6 = 8
Next, let's isolate the x term by adding 6 to both sides:
23x - 6 + 6 = 8 + 6
This simplifies to:
23x = 14
Finally, divide both sides by 23 to solve for x:
x = 14/23
So, the solution to the equation is x = 14/23.
To check the solution, substitute x = 14/23 back into the original equation:
3(14/23) - 6 = 4(2 - 3(14/23)) - 8(14/23)
This simplifies to:
42/23 - 6 = 8/23 - 12(14/23) - 112/23
-132/23 = -132/23
Both sides of the equation are equal, confirming that x = 14/23 is the correct solution.

Suppose a binomial trial has a probability of success of 0.3, and 500 trials are performed. What is the standard deviation of the possible outcomes? Round
your answer to two decimal places.
O A. 10.25
OB. 8.94
O c. 6.71
D. 10.95
The standard deviation of the possible outcomes is to be considered as the 10.25.
Calculation of the standard deviation:Since there is a binomial trial has a probability of success of 0.3, and 500 trials are performed.
So here
q = 1 - P
= 1 - 0.3
=0.7
Now the standard devation be like
[tex]= \sqrt{500\times 0.3 \times 0.7}[/tex]
= 10.25
hence, The standard deviation of the possible outcomes is to be considered as the 10.25.

Answer:
150 and -150
Step-by-step explanation:
For question number 2...
You started off with an energy level of 250 and something was added to make it 400.
To figure out what this "something" was, you simply subtract the numbers.
400 - 250 = 150
For question number 3...
You start off with 325 and end with 175. Here, the outcome is smaller or less than what you started with. So, you know that you took away a certain amount of energy. To figure that out, you again subtract.
325 - 175 = 150
To make the equation make sense, you would subtract 150.
So the answer would -150.

Answer:
9 cm.
Step-by-step explanation:
First, let's form an equation. We'll represent the final depth of snow on Cherry Street with the variable d. We'll represent the hours with the variable h.
10 - 1/3h = d
Now, you already know what h equals so you can replace h with 3 for 3 hours.
10 - 1/3(3) = d
1/3 * 3 = 1.
10 - 1 = d
10 - 1 = 9
Now, we know what d equals.
10 - 1/3(3) = 9.
Do NOT forget the unit of measurement in your final answer, cm. In the photo, it looks as though it has already been provided.
The final answer is 9 cm.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of grams and a standard deviation of grams while babies born after a gestation period of 40 weeks have a mean weight of grams and a standard deviation of grams. If a -week gestation period baby weighs grams and a -week gestation period baby weighs grams, find the corresponding z-scores. Which baby weighs relative to the gestation period?
Complete question :
Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900 grams while babies born after a gestation period of 40 weeks have a mean weight of 3100 grams and a standard deviation of 410 grams. If a 32 -week gestation period baby weighs 3300 grams and a 40 -week gestation period baby weighs 3600 grams, find the correspondingz-scores. Which baby weighs more relative to the gestation period? Find the corresponding z-scores. Which baby weighs relatively more?
Answer:
32 - 35 weeks = 0.56
40 weeks : 1.22
40 weeks babies weigh more
Step-by-step explanation:
Given that :
32 - 35 weeks babies :
Mean (m) = 2800
Standard deviation (s) = 900
Weight (x) = 3300
40 weeks babies :
Mean (m) = 3100
Standard deviation (s) = 410
Weight (x) = 3600
Obtain the standardized score for both categories :
Zscore = (x - m) / s
32 - 35 weeks :
Zscore = (3300 - 2800) / 900
Zscore = 0.555555 = 0.56
40 weeks :
Zscore = (3600 - 3100) / 410
Zscore = 1.2195121 = 1.22
Zscore for 40 weeks is higher than 32-35 weeks.
Hence, 40 weeks babies weigh more.
