Answer:

The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%

Step-by-step explanation:

Given that

Mean = μ = 15 points

SD = σ = 3 points

For calculating probability for a data point, first of all we have to calculate the z-score of the value.

We have to find the probability of score greater than 24, then the z-score of 24 is:

z-score = (x-μ)/σ

z = (24-15)/3

z = 9/3

z = 3

Now we have to use the z-score table to find the probability of z<3 then it will be subtracted from 1 to find the probability of z>3

So,

P(z3) = 1 - P(z

Converting into percentage

0.0013 * 100 = 0.13%

Hence,

The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%

What is one of the solutions to the following system of equations? y2 + x2 = 53 and y − x = 5
Aneli [31]
Y2 + x2 = 53
y − x = 5
y = 5 + x

(5+x)^2 + x^2 = 53
(5+x)(5+x) + x^2 = 53
25 + 10x + x^2 +x^2 = 53
2x^2 + 10x - 28 = 0
(x-2)(x+7)=0
x = 2 , x = - 7

y = 5 + 2
y = 7

y = 5 +(-7)
y = 5 - 7
y = - 2

I have no idea how to slove this 5x-5 =2×+97​
galina1969 [7]

Answer: x=34

Step-by-step explanation:

1. You subtract 2x from 5x on the other side to get rid of the 2x leaving you with 3x.

2. Then you add 5 to 97 to get rid of the -5, giving you 102 on the opposite side.

3. divide 102 by 3x giving you 34.

5x-5=2x+97

-2x     -2x

3x-5=97                                                                      <u><em>X=102</em></u>

   +5  +5

3x=102

x/3   102/3
