Let the number of weeks be x
38x + 209 = 1197
Subtract 209 on both sides
38x = 1197
Divide 38 on both sides
x = 31.5 weeks

Math workshops and final exams: The college tutoring center staff are considering whether the center should increase the number
ludmilkaskok [199]

Answer:

2. Number of workshops attended.

Step-by-step explanation:

The variable of interest for predicting the final exam score and doing regression analysis is workshop attendance.  Therefore, the response variable should be the number of workshops attended by each student.

This also agrees with what the college tutoring center staff are considering, which forms the research question: "should the center increase the number of math workshops they offer to help students improve their performance in math classes?"

Is 26 a perfect square? explain.
Aloiza [94]
No because if you were to square it you would get 5.099 and a perfect square is when it is the same number times each other to get a number for example: the square root of 9 is 3 so 3 times 3 is 9. 
 
Hope that helps!

The rate of change of the plane's altitude is 2250 feet per minute.

<h3>How to calculate the rate?</h3>

The rate of change of the plane's altitude will be:

= (35000 - 17000)/8

= 18000/8

= 2250 feet per minute.

When graphing the descent of the plane, the starting value for its altitude be 35000 feet.

The linear function will be:

y = mx + b

35000 = 2250x + b

35000 = 2250(0) + b

b = 35000

y = -2250x + 35000

The information given in this problem that did not need to write an equation for the descent is the initial details about how long that the plane travelled.
