Answer:

91

Step-by-step explanation:

|x − 10| = 3

x - 10 has two possibilities ----> +3 or -3

If x is +3 then the equation |x − 10| = 3 has the solution of x = 13

if x is -3 then the equation |x − 10| = -3 has the solution of x = 7

Now, multiply both to find the final answer.

7 × 13 = 91

You roll a 6-sided die.<br>What is P(prime)?<br>Write your answer as a percentage.<br>Submit​
Cloud [144]

You roll a 6-sided die. The probability of getting prime is 50%.

<u>Solution:</u>

Given, that we have rolled a 6 – sided die.

We have to find the P(prime) as percentage.

Now, It means that we have to find the probability of getting a prime number on the face.

On rolling a six sided die, the total possible outcomes are 1, 2, 3, 4, 5, 6

Number of possible outcomes = 6

We have to get a prime number on rolling a die

The prime numbers in possible outcomes are 2, 3, 5

So number of favorable outcomes = 3

\text {Probability of an event as percentage }=\frac{\text { favourable number of outcomes }}{\text { total number of outcomes }} \times 100

\text {Probability of getting prime number on face of die }=\frac{3}{6} \times 100

\begin{array}{l}{\text { P(prime) }=\frac{1}{2} \times 100} \\\\ {\text { P(prime) }=50 \%}\end{array}

Hence, probability of getting prime is 50%.
