It means to multiply those numbers. The answer is the first one.
(Look at image)
If your surveys are the following:
A. A survey of 110 teachers showed that 28 of them have a second job.
<span>B. A survey of 90 teachers showed that 27 of them have a second job. </span>
<span>C. A survey of 70 teachers showed that 21 of them have a second job. </span>
<span>D. A survey of 80 teachers showed that 32 of them have a second job.
</span>
Then the answer is B and C
<span>E[Y] = 0.4·1 + 0.3·2 + 0.2·3 + 0.1·4 = 2
E[1/Y] =0.4·1/1 + 0.3·1/2 + 0.2·1/3 + 0.1·1/4 = 0.4 + 0.15 + 0.0666 + 0.025?0.64
V[Y] =E[Y2]-E[Y]2= (0.4)·12+(0.3)·22+(0.2)·32+(0.1)·42-22= 0.4+1.2+1.8+1.6-4= 5-4 = 1</span>
YAAS! I literally learned this just a few weeks ago. (I am not actually a high school senior) First, convert 7% to a decimal, which is 0.07. Then multiply 0.07 by 23,000, giving you 1,610. This is your unit rate. I will though, need you to be more specific on "compounding quarterly" because I actually do not know what that means.
Answer:
44 dollars
Step-by-step explanation:
If you subtract 50 from 270 you get 220. Then you would divide 220 by 5 and get 44 dollars per day.
