Triangle MNO is similar to triangle RPO. Triangle M N O. Side M N is 20 kilometers and side M O is 32 kilometers. Triangle R P O. Side O R is 48 kilometers. Valek finds the distance between P and R. His work is shown below. Step 1 StartFraction 32 Over 48 EndFraction = StartFraction 20 Over P R EndFraction Step 2 20 P R = (32) (48) Step 3 20 P R = 1,536 Step 4 P R = 76.8 kilometers What is Valek’s first error? Valek did not correctly divide 1,536 by 20 going from step 3 to step 4. Valek did not find the correct product of 32 and 48 going from step 2 to step 3. Valek should have written the proportion in step 1 as StartFraction 32 Over 20 EndFraction = StartFraction P R Over 48 EndFraction. Valek should have written the cross-product in step 2 as 32 P R = (20) (48).

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
