Genetic experiment with peas resulted in one sample of offspring that consisted of 409 green peas and 152 yellow peas.
(a) construct a 90%confidence interval to estimate of the percentage of yellow peas.
(b) it was expected that 25% of the offspring peas would be yellow.
given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations?

is there answer choices?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

step-by-step explanation: i dont

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
