x = 43, AB = 49, BC = 49 and AC =98.

Solution:

Given data:

AC = 3x - 31  and AB = x + 6

B is the midpoint of AC.

Therefore AB = BC .

BC = x + 6

AB + BC = AC

x + 6 + x + 6 = 3x - 31

2x + 12 = 3x - 31

Add 31 on both sides, we get

2x + 43 = 3x

Subtract 2x from both sides, we get

43 = x

AB = x + 6

     = 43 + 6

AB = 49

BC = 49

AC = 3x - 31

     = 3(43) - 31

     = 129 - 31

AC = 98

Therefore x = 43, AB = 49, BC = 49 and AC =98.

Artemon [7]

Answer:

Part A

The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036

Part B

Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level

Part C

The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process

What is the area of this trapezoid
balandron [24]

Answer:

640.5 cm^2

Step-by-step explanation:

So the formula for trapezoid is height times the average of the bases. So 25+36=61, and then we divide that by 2 to get 30.5 as our average. Then, we take 30.5 and multiply it by 21 and we get 640.5.
