Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of th

krek1111 [17]

Answer:

$3 \sqrt{11}$

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

${a}^{2} + {b}^{2} = c {}^{2}$

where a and b are the legs and c is the hypotenuse l.

Let plug it in

${a}^{2} + 15 {}^{2} = {18}^{2}$

${a }^{2} + 225 = 324$

${a}^{2} = 99$

$a = \sqrt{99}$

$a = \sqrt{9 \times 11}$

$a = 3 \sqrt{11}$

The distribution of the number of graduate students over the past 13 years in the math department was: 1 69 2 445 3 347 4 0269 5

Sergio [31]

Answer:

largest number os students = 73

smallest number of students is 16

Step-by-step explanation:

Distribution of student over the period of 13 year is given in the following table

first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.

1 6 9

2 4 4 9

3 3 4 7

4 0 2 6 9

5

6

7 3

8

9

hence the graduate student number is calculated as

16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.

hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate

largest number os students = 73

smallest number of students is 16
