numbers.
Answer:
Step-by-step explanation:
Let the two whole numbers be 5x and 2x then
by the question
5x - 2x = 33
3x = 33
x = 33/3
x = 11
Therefore the numbers are
5x = 5*11 = 552x = 2*11 = 22hope it helps:)

A high school physics teacher was conducting an experiment with his class on the length of time it will take a marble to roll down a sloped chute. The class ran repeated trials in order to determine the relationship between the length, in centimeters, of the chute and the time, in seconds, for the marble to roll down the chute. A linear relationship was observed and the correlation coefficient was 0.964. After discussing their results, the teacher instructed the students to convert all of the length measurements to meters but leave the time in seconds. What effect will this have on the correlation of the two variables
Answer:
Step-by-step explanation:
Because changing from centimeters to meters does not affect the value of the correlation, the correlation will remain 0.964.
The effect does have on the correlation of the two variables should be that it remain the same i.e. 0.964.
Impact on the correlation of the two variables:Since there is the changing from centimeters to meters so this does not impact the correlation value due to which it remain the constant i.e. 0.964.
Also, the correlation coefficient should be unit -less and the value should always ranged between -1 to 1.
Therefore, it remains the constant.

can u help me find the area
Answer:
640 units squared
Step-by-step explanation:
The shape below is a trapezoid.
The formula for the area of a trapezoid is average of the bases times the height.
The bases are the parallel lines that make up 2 of the sides of the trapezoid.
The height is the line dotted line that creates right angles and is the distance between the two bases.
The bases are 24 and 40.
To find the average, we add them together and divide by 2
(24+40)/2=64/2=32
Now, we multiply 32 by the height, which is given as the length of 20.
32*20=640
the area of the trapezoid is 640 units squared
