-8x-2(5+4x)
Step-by-step explanation:
-8x-10-8x -8x-8x-10 -16x-10
Answer:
The null hypothesis is 
Step-by-step explanation:
According to the Centers for Disease Control and Prevention, the proportion of U.S. adults age 25 or older who smoke is .22
This means that at the null hypothesis, it is tested if the proportion is in fact 0.22, that is:
A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree or higher education level.
At the alternative hypothesis, it is tested if the proportion is lower than 0.22, that is:
The correct ratio for this problem is 3:4
<h2>The steps:</h2><h2>1) make 45 and 60 a fraction </h2><h2>2)45/60 simplify </h2><h2>3) once you simplfy you should get 3/4</h2><h2 /><h2>Steps in Numbers:</h2><h2>45/60 =3/4</h2><h2>60/45=4/3 convert 3/4</h2><h2>3/60=1/20 </h2><h2>3/45=1/15</h2><h2>Step 3:</h2><h2>60 divided into 48 as a fraction and simplify it </h2>
Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !
checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance
answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance
answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance
Conclusion : answer A
