The weight of a Great blue heron, a type of bird, can grow to around 4 pounds, but can vary. Let W be a random variable that represents the weight of a Great blue heron. The probability density function of W is given below. Move the left and right sliders so that the area of the blue shaded region represents the probability that a Great blue heron is at least 9 pounds, but no more than 10 pounds.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

the answer i believe is 27 units.

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

i think it will be 4feet long of what i comprehend
