You Spin a spinner it has 4 spaces. What is the probability that you spin a 3 and flipping heads
Anettt [7]

Answer:

12.5% or 1/8

Step-by-step explanation:

To find a compound probability multiply the likelihood of both events with each other.

Probability is how many things wished to be gotten over the total amount of possibilities for the event.

Spin a 3 on the spinner: 1/4 or 25% 1 space out of 4 spaces.

Flip the head side of the coin: 1/2 or 50% 1 side wish out of 2 sides.

1/4 x 1/2 = 1/8

1 divided by 8 = 0.125

0.125 x 100 = 12.5

12.5 is the the percentage.

If y varies directly as x and given y =9 when x= 5, fInd:
True [87]

Step-by-step explanation:

The statement

y varies directly as x is written as

<h3>y \:  \:  \alpha  \:  \: x</h3>

So we have

<h3>y = kx</h3>

First of all we must find the relationship between them

when

x = 5 and y = 9

We have

9 = 5k

Divide both sides by 5

k =  \frac{9}{5}

So the equation for the variation is

y =  \frac{9}{5} x

<h2>b).</h2>

when x = 15

y =  \frac{9}{5}  \times 15 \\  = 9 \times 3

We have the answer as

<h3>y = 27</h3>

<h2>c).</h2>

when y = 6

6 =  \frac{9}{5} x \\ 30 = 9x \\ x =  \frac{30}{9}

We have the answer as

x =  \frac{10}{3}

Hope this helps you
