A) 90-55=35 since a right angle is 90 total\
b)ii
Answer:
A.

Step-by-step explanation:
From the given information.
The proportion of American Millennials still with their parents = 0.36
The sample size = 300
Sample proportion = 0.43
Level of significance = 0.006
P-value = 0.006
Null hypothesis:



The required task is to determine the assumption about the sample that underlies the hypothesis test from the given options.
A.

This is because the student wants to check if the null hypothesis ( which states that of Millennial students at their campus, 36% live at home with their parents) is correct or not.
Answer:
x = 2
y = -1
Step-by-step explanation:
Since it gives you the value of y already, just plug that into the equation, like so:
y = 4x - 9
x - 3 = 4x - 9
<em><u>Subtract the x from both sides:</u></em>
x - 3 = 4x - 9
-x - x
__________
-3 = 3x - 9
<em><u>Then, add 9 to both sides:</u></em>
-3 = 3x - 9
+9 + 9
________
6 = 3x
<em><u>Divide both sides by 3:</u></em>
2 = x
<em><u>Now plug in x for y:</u></em>
y = x - 3
y = 2 - 3
y = -1
