To answer this, you first need to find 1%. You do this by dividing 102 by 85, which is 1.2. If 1.2 is 1%, then 1.2 × 100 is 100%. 1.2 × 100 = 129, which is your answer. I hope this helps!

You randomly draw a marble from a bag of marbles that contains 7 blue marbles, 2 green marbles, and 1 red
statuscvo [17]

Answer:

0.3 chance of not drawing a blue marble.

Step-by-step explanation:

This problem can be found using the theoretical probability formula.

The formula is: P (desired outcome) = <u># of desired outcomes</u>

                                                             total number of outcomes

Now all you have to do is input the numbers into the equation.

P(not drawing a blue marble) = <u>3</u>

                                                  10

3/10 is equal to 0.3 as a decimal.

Can someone help with factoring the trinomial
larisa [96]
X^2 - 13x + 40

as you know 40 = 5 x 8 or 40 = (-5) x (-8)
since -13x has -13 as coefficient so they should be (-5) and (-8)

x^2 - 13x + 40 = (x - 5)(x - 8)

(x - 5)(x - 8)
= x ^ 2 - 5x - 8x + 40
x ^ 2 - 13x + 40

so answer
D. (x - 5)(x - 8)
