Answer:

  3)  D

  4)  D

  5)  B

  6)  B

Step-by-step explanation:

3) A "Pythagorean triple" is a set of 3 integers that could be the sides of a right triangle. The only triangle shown with integer side lengths is choice D.

__

5) The only triangle for which the square of the hypotenuse is the sum of the squares of the other two sides is choice D.

  11² +2² = (5√5)²

  121 + 4 = 125

__

6) The lengths of sides of each right triangle are 2/3 of those of choice D in problem 4. That is, they are a 7-24-25 triangle, multiplied by 2. That means the height is 24·2 = 48, and the area is ...

  A = 1/2bh

  A = 1/2(28 m)(48 m) = 672 m² . . . . matches choice B

__

7) The side lengths of a 30-60-90 triangle have the ratios 1 : √3 : 2. That is, the short leg is half the hypotenuse, a fact stated in A and D. Those true statements make it clear that statement B is false.

The average commute times for employees of a large company is 32 minutes. The commute time of 10employees are 40, 31, 32, 16, 25
Ira Lisetskai [31]

Given:

40,31,32,16,25,35,22,53,23 and 33.

a)

Sample mean:

\bar{x}=32

Population mean:

\mu=\frac{\Sigma(x_i)}{n}_{}\mu=\frac{40+31+32+16+25+35+22+53+23+33}{10}\mu=\frac{310}{10}\mu=31

b)

\sigma=\sqrt[]{\frac{\Sigma(x-\mu)^2}{n-1}}\sigma=\sqrt[]{\frac{81+0+1+225+36+16+81+484+64+4}{10-1}}\sigma=\sqrt[]{\frac{992}{9}}\sigma=\frac{\sqrt[]{992}}{3}\sigma=10.4987\text{Error}=\pm z\times\frac{\sigma}{\sqrt[]{n}}

z value is not given so taken as 95% on confidence level

z=1.96\text{Error}=\pm1.96\times\frac{10.4987}{\sqrt[]{10}}\text{Error}=\pm6.5072\text{Error}=\pm6.5
