Insert three arithmetic means between 25 and 9

Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = $\frac{25+9}{2}$ = $\frac{34}{2}$ = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = $\frac{25+17}{2}$ = $\frac{42}{2}$ = 21 and

mean = $\frac{17+9}{2}$ = $\frac{26}{2}$ = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy. A carton o

Lemur [1.5K]

Given :

A carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.

To Find :

What was her first error.

Solution :

Her first error is to find Unit price of egg in each carton.

To find, unit price we should divide total amount by number of units :

Unit price for carton of 12 eggs, $ (2.39)/12 = $0.199 .

Hence, this is the required solution.

Find the slope of the line through the pair of points a (2,-3) p(2,9)

Katarina [22]

(x₁,y₁) = (2,-3)
(x₂,y₂) = (2,9)

To determine the slope using two points lie on the line, we could use the following formula
m = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

plug in the numbers
m = $\dfrac{9-(-3)}{2-2}$
m = $\dfrac{9+3}{0}$
m = $\dfrac{12}{0}$
m = undefined

The slope is undefined, the line is vertical
