Aspinner with 4 colors is spun for a total of 50 trials. yellow was selected 10 times. what is the experimental probability of the spinner landing on yellow?

I’m pretty sure the answer is 1/5 since yellow is selected 10 out of the 50 trials so if u simplify the fraction then 1/5 is the answer

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
