-4 1/2 x -3 3/4 <br> Does anyone know how to get the answer to that
taurus [48]
Hello there! Given the equation, we can solve through a series of steps:

1. Convert

In this step, we convert the mixed numbers to make them improper:

2 x 4 + 1 = 9, which means -4 1/2 = -9/2

4 x 3 + 3 = 15, which means -3 3/4 = -15/4

2. Multiply

Now that we have the improper fractions, we can multiply accordingly:

(-9/2 • -15/4) = -135/8

3. Simplify

Since we have our result, we can simplify to a mixed number:

-135/8 = 16 7/8

Your final answer is 16 7/8. Hope this helps!

A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 47.047.0 and
alisha [4.7K]

Answer:

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is between c and d is given by the following formula

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

For this problem, we have that:

a = 47, b = 57, c = 51.5, d = 51.75. So

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

P(51.5 \leq X \leq 51.75) = \frac{51.75 - 51.5}{57 - 47} = 0.025

0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
