Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 133 to 192 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x overbarequals167.21 cm, y overbarequals81.33 kg, requals0.326, P-valueequals0.001, and ModifyingAbove y with caretequalsnegative 108plus1.01x. Find the best predicted value of ModifyingAbove y with caret (weight) given an adult male who is 158 cm tall. Use a 0.05 significance level.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

answer is  

c.

36

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
