Answer:
B
Step-by-step explanation:
First off, we see that x ≥ -2. That little horizontal line right under the > sign indicates that x is "greater than or equal to" -2. Because we want to include -2 in the solution set, the dot on the number line at -2 should be shaded in.
This already eliminates A and D.
Now, we're left to choose between B and C.
Well, we know that x is greater than or equal to -2, so possible values of x should be numbers that are more positive than -2, or that point in the positive direction. That's exactly what B illustrates, so that's our answer.

Answer: 141
Step-by-step explanation:
Let p be the population proportion of adults over 50 never graduated from high school.
As per given , we have
Prior estimate of proportion for adults with 5 to 30 age graduated from high school group : p= 0.25
Significance level :
Critical z-value :
Margin of error : E= 0.06
Sample size will be :-
Simplify ,
Hence, the required sample size younger age group be surveyed = 141
