ratelena [41]

Answer:

14:6

7 x 3 = 21

3 x 3 = 9

What’s is x=5y for y
Margarita [4]

Answer:

y=\frac{x}{5}

Step-by-step explanation:

\frac{x = 5y}{5}

For the y to cancel out, you would have to divide y by 5. Whenever you do one thing to a side, you <u><em>have</em></u> to do the same on the other side. Once you do so, you'll get : \frac{x}{5}

<em>Hope this helps!!</em>

Can anyone help me on the last question?
Novosadov [1.4K]

Answer:

<h2>           0.7</h2>

Step-by-step explanation:

A' is everything what is not A

So:

    A' = {9, 10, 11, 12, 13, 15, 16}

Number of ways it can happen: |A'| = 7

Total number of outcomes: |Ω| = 10

Probability of an event happening:

                                         \bold{P(A')=\dfrac{|A'|}{|\Omega|}=\dfrac7{10}=0.7}
