A 6 sided cube with sides labeled 1,2,3,4,5 and 6 is rolled 50 times. What is a good prediction for the number of times 5 will b

Liono4ka [1.6K]

Answer:

A good prediction is that the number 5 will be rolled 8 times

Step-by-step explanation:

Here, we want to get the number of times 5 would occur in a roll of 50

firstly, we need the probability of having a 5 come up

To do this, we have to divide the number of 5’s by the count of possible numbers

We have this simply as 1/6

Now, we have to multiply this by 50

we have this as;

1/6 * 50 = 8.333

This is approximately 8

so we have it that in 50 rolls, we can have the number 5 coming up 8 times

-2 = -5t + 10t + 2t<br><br> t = ? <br> Help!

romanna [79]

Hello there!

$-2 = -5t + 10t + 2t\\$

Explanation:

↓↓↓↓↓↓↓↓↓

First you had to switch sides.

$-5t+10t+2t=-2$

Then you add similar elements.

$7t=-2$

Divide by 7 from both sides of the equation.

$\frac{7t}{7}=\frac{-2}{7}$

Simplify it should be the correct answer.

$t=-\frac{2}{7}$

Answer⇒⇒⇒⇒⇒t=-2/7

Hope this helps!

Thank you for posting your question at here on Brainly.

Can someone help me with this please?

Answer:

b. 28.1

Step-by-step explanation:

By the property of intersecting secant and tangent out side of the circle.

$20 \times (20 + x) = {31}^{2} \\ 20(20 + x) = 961 \\ 20 + x = \frac{961}{20} \\ 20 + x = 48.05 \\ x = 48.05 - 20 \\ x = 28.05 \\ \huge \red{ \boxed{ x = 28.1}}$
