Tara had just finished her first quilt. She marveled at the number of rectangles in the design. Tara showed the quilt to her sister, Alicia. "Look at all of the rectangles in the quilt," exclaimed Tara. "Rectangles?" asked Alicia. "I see five rows with five squares in each row. That's 25 squares. And, since a square is a special type of rectangle, there are 25 rectangles. Are there more that that?" Asked Alicia. How many rectangles are there in the quilt?

25.

Step-by-step explanation:

We can make this conclusion because from the question there was no mention of the number of columns in the quilt, and so we can make the assumption that the columns are one, that 1x1 (1 row, 1 column).

Hence, the rectangles in the quilt are going to be 25 (5 * 5 squares).

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.
