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.

okay wait before i answer, is this for your points on a graph?

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
