Answer:
a=86
Step-by-step explanation:
180=(a-42)+(a-3)+(180-(a+41))
180=2a-45+139-a
180-139=a-45
41=a-45
a=86
Answer:
Step-by-step explanation:
From the given information:
The null hypothesis and the alternative hypothesis can be computed as:
(i.e. there is no difference between the SAT score for students in both locations)
(i.e. there is a difference between the SAT score for students in both locations)
The test statistics using the students' t-test for the two-samples; we have:
t = 2.06
degree of freedom = (
) -2
degree of freedom = (45+38) -2
degree of freedom = 81
Using the level of significance of 0.05
Since the test is two-tailed at the degree of freedom 81 and t = 2.06
The p-value = 0.0426
Decision rule: To reject 
if the p-value is less than the significance level
Conclusion: We reject the , thus, there is no sufficient evidence to conclude that there is a significant difference between the SAT math score for students in Pennsylvania and Ohio.
Ok so the constant is 3:2 so if we do x for women then it would be x:40. To find x we do 40/2 which is 20 so then you multiply 20 to 3 to get the amount of women for every 40 men which is 60 women
B)60
40:60
I hope that helps
It is a rational number in the form of a decimal fraction.
Answer:
w = sa
Step-by-step explanation:
Given
s = 
( multiply both sides by a to clear the fraction )
sa = w
