For 9, do 0.5*6*9.2*5 to get the total area of the visual triangles, add that to 0.5*6*4.1*5 to get the area of the pentagon and you should get 199.5 cm^2for 10, do 0.5*6.9*8*12 to get the total area of the figure and you should get 331.2 cm^2
Associative property. (a•b)•c=a•(b•c)
Answer: (-2,-11)
Step-by-step explanation:
We looking for values that will satisfy the equation upon inspection, when x is -2, the equation gives y=-11 .
I.e y=4x-3 ,when x=2
Y= 4(-2)-3
Y= -8-3
Y= -11
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
3abc/abc = 3.
Simply put, the answer if you divide this equation by ABC, will quite literally transform into 3.
