Answer:
20
Step-by-step explanation:
Answer:
Prob = 95.0%
Explanation:
There are 382 people in total
69 respond and are in the 18-21 age bracket
12 refuse to respond and are in the 18-21 age bracket
282 respond and are in the 22-29 age bracket
19 refuse to respond and are in the 22-29 age bracket
Then, the number of people that are in the 18-21 age bracket or agreed to respond is
69 + 12 + 282 = 363
Therefore, the probability of getting someone in the 18-21 age bracket or someone who agreed to respond is
P = 363/382
P = 0.9502
P = 95.0 %
Answer:
x = 6
Step-by-step explanation:
I think it's supposed to be
y = x² - 12x + 36
Set the equation equal to zero and solve...
0 = x² - 12x + 36
Now factor. What 2 numbers add to -12, and multiply to 36?
-6 and -6, so our factors are
0 = (x - 6)(x - 6)
So
0 = x - 6, then
6 = x
A ratio that is equivalent to 8/3 is 16/6.
Because:- 8*2= 16
3*2=6
16/6 is equivalent to 8/3
Writing a proportion:-
8/3=16/6
