4+5+6= 15

There's 5 red out of 15 total marbles

5/15 or simplify to 1/3 if you divide by 5 so the answer is

5/15 or 1/3

If you have 15 total marbles and you're looking for the probability of choosing a red do 5/11=x/100 so the answer would be 45

<span>12x-4y=-8
y=3x+2 can sub for y in the first equation: 12x - 4(3x+2) = -8

Then 12x - 12x - 8 = - 8

This is true for all x, so there are infinitely many sol'ns.

The perimeter of a rectangle is 73 inches. The perimeter equals twice the length of L inches, plus twice the width of 11 inches.

Sindrei [870]

In mathematical form. you can write it as:
73 = 2 ( l + 11)

We can solve it for length,
73 = 2l + 22
2l = 73 - 22
l = 51/2
l = 25.5

Hope this helps!

Answer:

$0.1375$ to $0.3624$

Step-by-step explanation:

Given :The owner of a restaurant is reviewing customer complaints. In a random sample of 227 complaints, 57 complaints were about the slow speed of the service.

To Find :Create a 95% confidence interval for the proportion of complaints that were about the slow speed of the service.

Solution:

n = 227

x = 57

Formula of confidence for proportion: $\widecap{p}-z_{\frac{\alpha}{2}}\sqrt{\frac{\widecap{p}\widecap{q}}{n}}$ to $\widecap{p}+z_{\frac{\alpha}{2}}\sqrt{\frac{\widecap{p}\widecap{q}}{n}}$
