Answer:

The distance between E and F is 5 units

Step-by-step explanation:

E and F are share the same y-coordinates. So for this part it is okay to not use the distance formula. 

So you will be having:

E (5,8) and F (5,3)

EF = 8-3=5

OR 

YOU CAN USE THE DISTANCE FORMULA AS INDICAYED IN THE PICTURE.

Hopefully the picture is clear and understandable and younger the explanation.

Dafna11 [192]

Answer:

Average salary: 56

Standard deviation of the salary: 8

Step-by-step explanation:

$56,000 dollars is 56 thousand dollars.

$8,000 is 8 thousand dollars.

The mean is the average. So the average, measured in thousands of dollars, is 56.

The standard deviation is $8,000. So, the standard deviation measured in thousands of dollars, is 8.

Find a formula for the nth term of the geometric sequence. Assume the n begins with 1. a1=18, a2=9

LUCKY_DIMON [66]

Answer:

Option E

Step-by-step explanation:

Explicit formula of a geometric sequence is,

$T_n=a_1(r)^{n-1}$

Here, $a_1=$ First term

$r=$ common ratio

$n=$ number of terms

If, $a_1=18$ and $a_2=9$

Common ratio of the sequence $r=\frac{a_2}{a_1}$

$r=\frac{9}{18}$

$r=\frac{1}{2}$

By substituting these values in the formula,

$T_n=18(\frac{1}{2} )^{n-1}$

Therefore, Option E is the answer.
