Answer:

AC = 6 cm

Step-by-step explanation:

First, realize that these are two identical triangles. We just have to use the pythaogrean theorem on one side to find AD or DC, then multiply that by 2 to get AC.

a^2 + b^2 = c^2

8^2 + b^2 = 10^2

64 + b^2 = 100

100 - 64 = b^2

b^2 = 36

b = 6

YW bisects <XYZ. m<XYW=(2x+7) and m<XYZ= (6x-8). find the value of the X and the measure of <XYZ

Alina [70]

See Image first.

Finding X
2. 2(2x+7) = 6x-8
3. 4x + 14 = 6x -8
4. 22 = 2x
5. x = 11

Finding m<XYW
2x + 7
2 ( 11) +7
29 degrees

Finding m<XYZ
2(2x+7)
4x + 14
4 * 11 + 14
58 degrees

CHECK:
6x -8
6 (11) - 8
58 degrees (CHECK!)

ANSWER: x= 11
m<XYZ = 58 degrees

1) Suppose the heights of 18-year-old men are approximately normally distributed, with mean 71 inches and standard deviation 5 i

Luba_88 [7]

Answer:

Suppose the heights of 18-year-old men are approximately normally distributed, with mean 71 inches and standard deviation 4 inches.

(a) What is the probability that an 18-year-old man selected at random is between 70 and 72 inches tall? (Round your answer to four decimal places.)

z1 = (70-71)/4 = -0.25

z2 = (72-71/4 = 0.25

P(70<X<72) = p(-0.25<z<0.25) = 0.1974

Answer: 0.1974

(b) If a random sample of thirteen 18-year-old men is selected, what is the probability that the mean height x is between 70 and 72 inches? (Round your answer to four decimal places.)

z1 = (70-71)/(4/sqrt(13)) = -0.9014

z2 = (72-71/(4/sqrt(13)) = 0.9014

P(70<X<72) = p(-0.9014<z<0.9014) = 0.6326

Answer: 0.6326

What is the total weight for each group of weight of clay lumps

Verizon [17]

Hey, me again! So, I'll be giving you the totals for EACH group.

For the first group, multiply 1/8 by 3 to get the answer;
3/8 lbs

Do the same for this group (and all of the others) so that the answers are:
Group 2 - 3/4lbs
Group 3 - 2/2 = 1lb
Group 4 - 5/8lb
Group 5 - 7/8
