The number of paper clips that Crystal has is 42 divided by the number of paper clips that Gayle has. If

Nikolay [14]

Answer:

The number of paper clips that Crystal has is 3 and the number of paper clips that Gayle has is 14

Step-by-step explanation:

Let

x----> the number of paper clips that Crystal has

y ---> the number of paper clips that Gayle has

we know that

$y=x+11$ ----> equation A

$x=42/y$ ----> equation B

substitute equation A in equation B

$x=\frac{42}{x+11} \\ \\x^{2} +11x=42\\ \\x^{2} +11x-42=0$

Solve the quadratic equation by graphing

The solution is $x=3\ paper\ clips$

see the attached figure

Find the value of y

$y=3+11=14\ paper\ clips$

therefore

The number of paper clips that Crystal has is 3

The number of paper clips that Gayle has is 14

1) The probability of rolling a 1 is 10/40 and the probability of rolling a 5 is 6/40. Add these together to get 16/40 which simplifies to 2/5 probability of rolling a 1 or 5.

2) The probability of the spinner landing on section 2 is 36/80 which simplifies to 9/20

3) To find the relative frequency, divide each number by the total number of trials. In this case we're only look at the clubs so divide 8/40, which is 0.2 or 20%

4) There were 60 trials total and since we're finding the relative frequency of red, divide 13/60 which is 0.216 rounded to 0.22 or 22%

5) The spinner is spun 84 times and it lands on A 14 times so the probability of it landing on A is 14/84 which simplifies to 1/6 or 0.166 rounded to 0.17 or 17%

I hope this helps you!
