Can someone please help me

stepladder [879]

5)

x = 132 - 42

x = 90

Answer

90 degrees, right angle

6)

180 - 126 = 54

The other two are congruent so 54/2 = 27

Answer

27

7)

An exterior angle of a triangle is equal to the sum of the opposite interior angles

So

6x = 38 + 82

6x = 120

x = 20

Answer

20

8)

Sum of interior in a triangle = 180 degrees

So

2x - 3 + 23 + 128 = 180

2x + 148 = 180

2x = 32

x = 16

Answer

16

The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches. Use the Empiric

maks197457 [2]

Answer: c)[50,60]

Step-by-step explanation:

The Empirical rule says that , About 68% of the population lies with the one standard deviation from the mean (For normally distribution).

We are given that , The heights of students in a class are normally distributed with mean 55 inches and standard deviation 5 inches.

Then by Empirical rule, about 68% of the heights of students lies between one standard deviation from mean.

i.e. about 68% of the heights of students lies between $\text{Mean}\pm\text{Standard deviation}$

i.e. about 68% of the heights of students lies between $55\pm5$

Here, $55\pm5=(55-5, 55+5)=(50,60)$

i.e. The required interval that contains the middle 68% of the heights. = [50,60]

Hence, the correct answer is c) (50,60)
