IRISSAK [1]

Answer: B. 31

Step-by-step explanation:

This linear regression was constructed by relating the hours practiced per week and the number of competitions won.

Going by this graph, the number of competitions they can expect to win at 5 practices a week is 31.

This is derived by looking for the point where 5 competitions on the x-axis intersects with the line. This point is at 31 competitions on the y axis which would make it the answer.

Megan went to the beach 34 times last summer. She went 6 more times in July than she did in June. She went twice as many times i

Irina-Kira [14]

<span>Megan went to beach 34 times last summer.
June = x
July = 6 * june
August = 2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
