Answer:
The diagonal length of the square equals:
diagonal ^ 2 = 7^2 + 7^2
diagonal ^ 2 = 49 + 49
diagonal ^ 2 = 98
diagonal = 9.899 cm
The diagonal is smaller than the circle's diameter and so it will ft inside the circle.

Given : Sample size
Sample mean :
Sample standard deviation :
Let be the population mean of "like" ratings of male dates made by the female dates.
As per question ,
Null hypothesis :
Alternative hypothesis : , It means the test is a one-tailed t-test. ( we use t-test when population standard deviation is unknown.)
Test statistic:
For 0.05 significance and df =188 (df=n-1) p-value = .001582. [By t-table]
Since .001582< 0.05
Decision: p-value < significance level , that means there is statistical significance, so we reject the null hypothesis.
Conclusion : We support the claim at 5% significance that t the population mean of such ratings is less than 8.00.

Answer:
15 square feet
Step-by-step explanation:
Y2-Y1 over X2-X1 to find slope first
-7-(-2)/4-5=-5/-1 or 5 since a negative and a negative makes a positive
Your slope is 5 now you use mid point formula to find your actual equation
Y-Y1=M(X-X1)------Sub in 5 for M in mid point formula--your first cord points (5,-2) will be used
Y-(-2)=5(X-5)----a negative and a negative makes a positive -(-2) Y+2=5(X-5)--then you distribute 5 into X and -5 which will be 5X-25
now you should have Y+2=5X-25
Subtract 2 from both sides and then you should have your equation passing through (5,-2) and (4,-7)
Y=5X-27
