3(v + 2) + 4 = 13 HELP ME!!

Zolol [24]

3(v + 2) + 4 = 13

Mutiply the bracket by 3

(3)(v)= 3v

(3)(2)= 6

3v+6+4= 13

3v+10=13

Move +10 to the other side

Sign changes from +10 to -10

3v+10-10= 13-10

3v= 13-10

3v= 3

divide both sides by 3

3v/3= 3/3

v= 1

Answer : v= 1

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is

Talja [164]

Answer:

The standard error of the mean = 2

Step-by-step explanation:

Given that:

The standard deviation σ = 14

The sample size n = 49

The sample mean $\overline x$ = 56

The formula for calculating the standard error can be expressed as:

$S.E = \dfrac{\sigma}{\sqrt{n}}$

$S.E = \dfrac{14}{\sqrt{49}}$

$S.E = \dfrac{14}{7}$

S.E = 2

Therefore, the standard error of the mean = 2

Answer:

$33.25

Step-by-step explanation:

Taking Eric's hours as a ratio to the total hours :

3.5 : 3.5 + 2
3.5 : 5.5
3.5 x 2 = : 5.5 x 2
7 : 11

Multiply the ratio into the amount paid :
