Answer: Distributive Property

The term "distribution" is also used in place of "distributive"

This property says

x*(y+z) = x*y + x*z

We multiply the outer term x with each inner term (y and z). Then we add the results.

In this case,

x = 5

y = a

z = 3b

So,

5(a+3b) = 5*a + 5*3b = 5a+15b

assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob

melamori03 [73]

Answer:

$P(x$

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

$P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}$

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

$P(x$

Then:

$P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}$

$P(x\leq3)=0.0994$

X+2.6=1.7 how do you do this

Genrish500 [490]

X+2.6=1.7
x+12=7
x+12-12=7-12 (subtract 12 from both sides)
x=-5

alukav5142 [94]

Answer:

10 more girls

Step-by-step explanation:

So here 2/3 of 24 ran for first race

Then it gives us that 16 girls ran for first race.

Next, 1/4 of 24 ran for second race

That is 6 girls

The remaining girls ran for the third race,

24 - 22

2 girls

16 - 6 = 10

So for first race 10 more girls ran
