You multiply the denominator by the whole number then add the numerator. example: 2 2/5= 12/5

You see how many times the denominator can fit into the numerator, then that becomes a whole number and whatever's left over becomes the new numerator.

For example: 7/5

5 goes into 7 once with a remainder of 2

1 and 2/5 would be your mixed number

What are the values of a and b?

Helen [10]

A is 6 because so is the side across from it

And B is 8 because it the same size just flip it

Expand (3x+7)(3x-7) =

saveliy_v [14]

Answer:

$9 {x}^{2} - 49$

Step-by-step explanation:

Do FOIL, first outside inside last

3x × 3x = 9x^2

3x × -7 = -21x

7 × 3x = 21x

7 × -7 = -49

$9 {x}^{2} - 21x + 21x - 49 \: midde \: cancels \: each \: other \: out$

So it would just be 9x^2 - 49

Suppose the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes. W

butalik [34]

Answer:

C) Uniform distribution

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely. In this case, the probability of producing a defective light bulb from a production line is the same over an interval of 90 minutes, so the correct answer is C.

We can calculate the probability.

Uniform probability distribution

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 given by the following formula.

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