calcula la diagonal de un cuadrado cuyo lado tiene cada una de las siguientes medidas en centímetros. a.4 b.7 c.13

The length of diagonal is for (a=4) is , for(a=7) is and for (a=13) is.

Given side of squares.

We have to calculate the length of diagonal.

We know that in square shape,

length of diagonal , here a is the side of square.

So when square has a side of 4 then its diagonal becomes .

when square has a side of 7 then its diagonal becomes .

when square has a side of 13 then its diagonal becomes .

Hence the length of diagonal is for (a=4) is , for(a=7) is and for (a=13) is.

Step-by-step explanation:

Well the diagonal using pythagora's theorem:

where x is the lenght is the side of the square

so when x=4

when x=7

when x=13

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.
