Answer:

You would do the change in y over the change in x.

That means you subtract your y values and that's the numerator. Subtract your x values and that is your denominator. Then simplify.

A bathtub is the shape of a rectangular prism. The dimensions are 5 1/2 ft times 2 1/2 ft times 2 3/4 ft. What is the volume of

Sav [38]

Answer:

$37 \frac{13}{16} ft^3$

Step-by-step explanation:

A rectangular prism is also know as a cuboid.

The dimensions of the rectangular prism shaped bath tub are 5½ ft * 2½ ft * 2¾ ft.

The volume of a cuboid (rectangular prism) is given as:

V = L * B * H

Hence, the volume of the bath tub is:

V = 5½ * 2½ * 2¾

V = 11/2 * 5/2 * 11/4

V = 605 / 16 = $37 \frac{13}{16} ft^3$

The volume of the bath tub is $37 \frac{13}{16} ft^3$

Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance

Feliz [49]

Answer:

9.5

Step-by-step explanation:

Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance.

Step 1

We find the Mean of the numbers

Mean = Sum of terms/ Number of terms

Mean = 9+12+9+14+6/5

= 50/5

= 10

Step 2

We find the sample variance

Formula =

(x - Mean)²/n - 1

n = 5

= (9 - 10)²+(12 -10)²+(9- 10)²+(14-10)²+(6-10)²/5 - 1

= 1+ 4+ 1+ 16+16/5 - 1

= 38/5 - 1

= 38/4

= 9.5

Therefore, Sample variance = 9.5

Graph the linear equation using the slope and y-intercept.<br> Y=4X+3

JulsSmile [24]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have y = 4x + 3

m = 4 - slope

3 - y-intercept

$m=\dfrac{\Delta Y}{\Delta x}\to4=\dfrac{4}{1}$

4 units up and 1 unit right
