Answer:

The correct answer is option B. 140

Step-by-step explanation:

From the figure we can see that,

AB ║ CD

<u>To find the value of x</u>

From the figure we can see that,

<CFE = <BEF      [Alternate interior angles are equal]

4x + 20 = 5x - 10

5x - 4x = 20 + 10

x = 30

<u>To find the measure of <BEF</u>

m<BEF = 5x - 10

 = (5*30) - 10

 = 150 - 10

 = 140°

Therefore the correct answer is option B. 140

Answer:

a) Robert, Juan, linda

b) Joel

c) Susan, Jan

d)    165.4

       173.4

       134.5

       156

       147.3  

       170.2

       

Step-by-step explanation:

The standardized normal distribution  N (0,1)  that expresion stands for normal distribution with mean 0 and standard deviation 1, therefore all positive values are above 0 and all negativa values are below 0

The sample n is 6 then we should use t-student distribution, we calculate t statistic as follow

t = (x-μ)/εε        where standard error is   εε = σ/√6      εε = 9.795  since         σ =24

Robert

0.96 * 9.795  = x - 156                 ⇒     x = 165.4

1.78 * 9.795  = x  - 156                          x = 173.4

-2.2 * 9.795   = x - 156                          x = 134.5

0 * 9.795        = x- 156                          x= 156

-0.89* 9.795   = x -156                          x = 147.3

1.45 * 0.9795  = x -156                         x = 170.2
