Suppose the heights (in inches) of men (ages 20–29) years old in the United States are normally distributed with a mean of 69.3 inches and a standard deviation of 2.92 inches. 1. The percent of men who are between 63.46 inches and 75.14 inches tall.

2. The percent of men who are taller than 72.22 inches.

3. The percent of men who are between 60.54 inches and 78.06 inches tall.

4. The percent of men who are shorter than 60.54 inches.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

if she was to only spend a dollar she can get 1lb

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
