A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weig

ht is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. Find the probability that the mean actual weight for the 100 weights is greater than 24.9. (Round your answer to four decimal places.)

Answer:

0.45

Step-by-step explanation:

For a uniform distribution,

f(x) = \frac{1}{b - a} \\

where a is the minimum and b the maximum\\

cumulatively, F(x) = \frac{x - a}{b -a}

F(x >= 24.9) = \frac{24.9 - 24}{26 - 24} = \frac{0.9}{2} = 0.45

It’s for my geometry class and I don’t know how to solve it. Can someone please help me?
dusya [7]

Answer:

Below in bold.

Step-by-step explanation:

Because the 2 sides marked with the double lines are equal:

5y-1 = 2y+11

3y = 12

y = 4.

Also :

3x-5 + 2(2x+5) = 180

3x - 5 + 4x + 10 = 180

7x = 180 + 5 -10

7x = 175

x = 175/7 = 25.
