Answer:

Step-by-step explanation:

There are 7 pieces of data. So you can eliminate B and D immediately because they only have 6 data points on them.

Now if you look closely at A and C, the only difference is the point near the 14. In the list of data, the point near 14 is 14.125, so the point should be near BUT PASSED (above, to the right of) 14.

C is not the answer because the point near 14 is more like on 13.75. So A is the best answer.

Answer: The answer is C.

Step-by-step explanation:

If you look at C. you can see three dots 11.25, one dot 10. 5, one dot 12, one dot 12.5, and one dot 14.125. That correctly places all number on the line. I hope i help if im wrong sorry.

Use the given conditions to write an equation for the line in point-slope form.

Alex17521 [72]

Step-by-step explanation:

Hey there!

The given slope is; 3. And passing through point (-7,8).

Now,

Using one point formula.

$(y - y1) = m(x - x1)$

Put all values to find equation.

$(y - 8) = 3(x + 7)$

Simplify them to get answer.

$(y - 8 )= 3x + 21$

$3x - y + 21 + 8 = 0$

$3x - y + 29 = 0$

Therefore the required equation is 3x-y+29=0.

Hope it helps...

A solid piece of wood shaped as a cylinder with an 8-centimeter diameter is cut as shown. What is the surface area of the figure

aliina [53]

The surface area of the figure is 96 + 64π ⇒ 1st answer
Step-by-step explanation:
* Lats revise how to find the surface area of the cylinder
- The surface area = lateral area + 2 × area of one base
- The lateral area = perimeter of the base × its height
* Lets solve the problem
- The figure is have cylinder
- Its diameter = 8 cm
∴ Its radius = 8 ÷ 2 = 4 cm
- Its height = 12 cm
∵ The perimeter of the semi-circle = πr
∴ The perimeter of the base = 4π cm
∵ The area of semi-circle = 1/2 πr²
∴ The area of the base = 1/2 × π × 4² = 8π cm²
* Now lets find the surface area of the half-cylinder
- SA = lateral area + 2 × area of one base + the rectangular face
∵ LA = perimeter of base × its height
∴ LA = 4π × 12 = 48π cm²
∵ The dimensions of the rectangular face are the diameter and the
height of the cylinder
∴ The area of the rectangular face = 8 × 12 = 96 cm²
∵ The area of the two bases = 2 × 8π = 16π cm²
∴ SA = 48π + 16π + 96 = 64π + 96 cm²
* The surface area of the figure is 96 + 64π

Please only math geniuses help, what is x+1/5y=-6 in slope intercept form?

weeeeeb [17]

Y=-5x-30.

Subtract from each side (1/5y=-x-6 )
Then multiply by 5/1 on both sides to get rid of the 1/5 (y=-5x-30)
