Suppose the x-axis of a density graph represents someone's weight in pounds. if the area under the density graph from 120 pounds to 160 pounds is 0.46, what is the probability of someone's weight being anywhere from 120 pounds to 160 pounds?

Another Apex Question Like This:

Suppose the x-axis of a density graph represents someone's weight in pounds. If the area under the density graph from 120 pounds to 140 pounds is 0.28, what is the probability of someone's weight being anywhere from 120 pounds to 140 pounds?

(28% Is answer to this question)

Step-by-step explanation:

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
