It is assumed that the time customers spend in a record store is uniformly distributed between 3 and 12 minutes. Based on this i

monitta

Answer:

0% probability that a customer will be exactly 7.50 minutes in the record store.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

The uniform distribution is a continuous distribution, which means that the probability of an exact outcome is zero.

Uniformly distributed between 3 and 12 minutes.

This means that $a = 3, b = 12$

What is the probability that a customer will be exactly 7.50 minutes in the record store?

Continuous distribution, so:

0% probability that a customer will be exactly 7.50 minutes in the record store.

If 0.9x-1.3=-3.1, what is the value of x-0.8?

Butoxors [25]

−2.8
Okay so "0.9x-1.3=-3.1" x=-2

0.9x−1.3=−3.1

add 1.3 to both sides

0.9x−1.3+1.3=−3.1+1.3

0.9x=−1.8

divide both sides by 0.9

0.9x/0.9=−1.8/0.9

x=−2

So if you plug in -2 into "x-0.8" you get −2.8

=−2−0.8

=−2-0.8

=−2.8

Hope this helps.
