we have the data set

3,1,7,0,4

step 1

Find out the sample mean

sample mean=(3+1+7+0+4)/5

sample mean=15/5

sa,ple mean=3

step 2

Complete the table

x (x-mean) (x-mean)^2 x^2

3 (3-3) (3-3)^2 0

1 (1-3) (1-3)^2 4

7 (7-3) (7-3)^2 16

0 (0-3) (0-3)^2 9

4 (4-3) (4-3)^2 1

--------------------------------------------------------------------------

15 30

Find out the standard deviation of the sample

SD=√(30/n-1)

SD=√(30/5-1)

SD=2.74

What is the equation of the line that has a slope of 3 and goes through point (4, 7)?
astra-53 [7]
<span>The slope of the line is equal to (y - 7) / (x - 4)
Then we can set up this equation:
(y - 7) / (x - 4) = 3
y - 7 = 3 * (x - 4)
y - 7 = 3x - 12
y = 3x - 5
This is the equation of the line.</span>

Bh+hr=25 solve for r please work it out step by step
denis23 [38]

So firstly, factor out h on the left side: h(b+r)=25

Next, divide both sides by h: b+r=\frac{25}{h}

Lastly, subtract both sides by b and your answer will be r=\frac{25}{h}-b

3(2v-1)=6v-4 can someone pls help me with this
ZanzabumX [31]

Answer:

Step-by-step explanation:

dy/dx= -(2x+3y+1)/(3x-2y+1)

Let x= X+p. and y = Y+q. then dy/dx = dy/dX.

dy/dX= -(2X+2p+3Y+3q+1)/(3X+3p-2Y-2q+1) =

dy/dX = -{2X+3Y+(2p+3q+1)}/{3X-2Y+(3p-2q+1)}

Now 2p+3q+1=0……………..(1)

3p-2q +1=0…………………………(2)

p/(3+2)=q/(3–2)=1/(-4–9)

Persia make a flower arrangement using the eight longest flowers which is the combined height of flowers Persia uses
andriy [413]

Answer:

Persia should measure the length of each flower that she used in creating this flower arrangement and add up all the values to get the total height (i.e., the combined height) of the eight flowers used. Make sure to keep the units consistent all throughout the calculation to avoid any errors. For example, if centimetres are used to measure height of one flower, use centimetres all throughout and not switch to using inches at any point.

Hope that answers the question, have a great day!
