Donna is hanging a poster on her wall she wants to center it horizontally. The poster is 25 7/10 inches long, the space between the right edge of the poster and the right edge of the wall is 50 1/4 inches in the wall is 134 1/5 Inches long. Is the picture centered? Use the numbers given to find out, and use estimation to check if your answer is reasonable.

Step-by-step explanation:

In the image attached you can observe a representation of this situation.

First, we need to transform each mixed number to a fraction.

Now, if the poster is centers, then the distance to the wall on the right and on the left, must be equal. We know that the space on the right is 50.25 inches. Then, we subtract to find the other side

So, the space in the left side of the poster is 58.25 inches long.

Therefore, the poster is not centered.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
