Help me please! Ray BD is the angle bisector.What is the value of x?
Montano1993 [528]

Answer:

x = 4

Step-by-step explanation:

An angle bisector divides an angle into two equal parts.  This means that you can set the two parts equal to each other and solve for x.

8x + 35 = 11x + 23

(8x + 35) - 35 = (11x + 23) - 35

8x = 11x - 12

8x - 11 x = (11x - 12) - 11x

-3x = -12

(-3x)/-3 = -12/-3

x = 4

The researcher has limited resources. He sends 9 emails from a Latino name, and 14 emails from a non-Latino name. For the Latino
deff fn [24]

Answer: 38.41 minutes

Step-by-step explanation:

The standard error for the difference in means is given by :-

SE.=\sqrt{\dfrac{\sigma_1^2}{n_1}+\dfrac{\sigma^2_2}{n_2}}

where , \sigma_1 = Standard deviation for sample 1.

n_1= Size of sample 1.

\sigma_2 = Standard deviation for sample 2.

n_2= Size of sample 2.

Let the sample of Latino name is first and non -Latino is second.

As per given , we have

\sigma_1=82

n_1=9

\sigma_2=101

n_2=14

The standard error for the difference in means will be :

SE.=\sqrt{\dfrac{(82)^2}{9}+\dfrac{(101)^2}{14}}

SE.=\sqrt{\dfrac{6724}{9}+\dfrac{10201}{14}}

SE.=\sqrt{747.111111111+728.642857143}

SE.=\sqrt{1475.75396825}=38.4155433158\approx38.41

Hence, the standard error for the difference in means =38.41 minutes
