10(1/2x + 5) = 7
That's the way to write the description of that equation. Good luck!!
Answer:
17.0
Step-by-step explanation:
right angle with angles 45, 45 and 90
SOHCAHTOA
cos 45 = A/H
Cos 45 = 12/r
r= 12/cos 45
r= 16.97
Answer:
225 in3

Answer:
The right answer is:
"The one-day SAT prep class produces statistically significant improvements in SAT writing performance."
Step-by-step explanation:
The P-value gives us the probability of getting the sample results, given that the null hypopthesis is true. That is why, it the P-value is small enough (smaller than the level of significance) is an indicator that the null hypothesis may not be true.
In this case, the P-value (0.028) is smaller than the level of significance (0.05), so the null hypothesis is rejected and we can conclude that there is significant difference for the studentes that take the SAT prep-class.
The population only include the students that take teh SAT prep-class, so it is not useful to compare to the performance of students that didn't take the class.
The right answer is:
"The one-day SAT prep class produces statistically significant improvements in SAT writing performance."
Answer:
The standard deviation of the distribution is 21.7 students.
Step-by-step explanation:
We are given the following in the question:
We treat college student living on campus as a success.
P(college student living on campus) = 0.38
Then the number of students follows a binomial distribution.
Sample size, n = 2000
We have to evaluate the standard deviation of the distribution.
Formula:
Putting values, we get,
Thus, the standard deviation of the distribution is 21.7 students.
