The table below shows the probability distribution of student ages in a high school with 1500 students. What is the expected value for the age of a randomly chosen student? Age 13 14 15 16 17 18 Probability 0.01 0.27 0.30 0.25 0.16 0.01 O A. 15.38 OB. 15.31 O C. 15.50 D. 15.35 SUBNET​

According to me it should be Option B, 15.31

Hope this helps!

B, 15.31

Step-by-step explanation:

Expected value is just probabilty*outcome

so it's just the sum of probability*age

.01*13+14*.27+15*.3+16*.25+17*.16+18*.01= 15.31

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
