Five whole numbers are written in order

xenn [34]

Answer:

The values of x and y is given by the equation $4x-y=20+y$ .

Step-by-step explanation:

Given : Five whole numbers are written in order 4 6 x y 10 , the mean and median of the five numbers are the same.

To find : The values of x and y ?

Solution :

Observations 4, 6, x, y, 10.

Mean is summation of observation divided by number of observation.

i.e. $m=\frac{\sum x_n}{n}$

$m=\frac{4+6+x+y+10}{5}$

$m=\frac{20+x+y}{5}$

Median is middle term of observations.

Median of odd terms $M=\frac{n+1}{2}^{th}$ term

$M=\frac{5+1}{2}^{th}$

$M=3^{rd}$ term

$M=x$

The mean and median of the five numbers are the same.

i.e. $\frac{20+x+y}{5}=x$

$20+x+y=5x$

$4x-y=20+y$

The values of x and y is given by the equation $4x-y=20+y$ .

A paper company needs to ship paper to a large printing business. The paper will be

Tcecarenko [31]

Answer:

10 small boxes and 12 large boxes

Step-by-step explanation:

Let x = number of large boxes

Let y = number of small boxes

We are told that;

volume of each small box = 6 cubic feet

volume of each large box = 22 cubic feet.

Total volume = 324 ft³

Thus;

6x + 22y = 324 - - - (eq 1)

We are told that 22 boxes of paper were shipped.

Thus; x + y = 22 - - - (eq 2)

Making x the subject in eq 2 gives;

x = 22 - y

Put 22 - y for x in eq 1;

6(22 - y) + 22y = 324

132 - 6y + 22y = 324

16y = 324 - 132

16y = 192

y = 192/16

y = 12

So, x = 22 - 12 = 10

Given f(x)=x^2-4x+5, what's the value when f(2)

Reil [10]

If you were to replace the x's with 2, your equation would turn into:

(2)^2-4(2)+5

From there, you'd just solve.

4-8+5=1

Your answer would be 1.

Plzz help. Giving everything.<br> D. 24.5

Lemur [1.5K]

Answer:

$\frac{8}{14} = \frac{14}{x+2}$ (since they're similar, set them up as a proportion to find x)

14*14 = 8(x+2) (cross multiply, solve the left side, and distribute the right side)

196 = 8x +16 (subtract 16 from both sides)

180 = 8x (divide both sides by 8)

x= 22.5 (is your answer, or C)
