Use the surface area formula of: $2 \pi rh+2 \pi r^2$ .
$2 \pi r^2$ refers to the two faces of the areas of the circle, and the first part ( $2 \pi rh$ ), refers to the side of the cylinder that is not the circles, which is the circumference times the height. By using this formula, you would get approximately 282.74 yards.

Houw would i factor this problem out completely?

kvasek [131]

You can factor out a 3t first, resulting in:
$3t(2t^2+3t-5)$

Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:
$\frac{-3\pm \sqrt{3^2-4(2)(-5)}}{2(2)} = -\frac{3\pm \sqrt{49}}{4} = -\frac{3\pm 7}{4}$

Simplify, you get your x's:
$x = 1, -\frac{5}{2}$

To write the equation in simplified form, you just write it this way:
$3t(x-1)(2x+5)$

That's your answer ^

I If the game with 3 hits is considered to be recorded in error, it might be removed from the data set. If that happens a. What

Flura [38]

Answer:

If the game with 3 hits is ignored the data becomes:

7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11

a) The mean will increase.

(3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9

<u>Without 3:</u>

(7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21

b) The median will remain as is.

With 3 and without the median is same = 9

Jax solved an equation and justified his steps as shown below. What reason would justify step 2?

koban [17]

Answer: The Subtraction Property of Equality

In the problem that Jax solved he subtract 5 from both sides of the equation. This is an example of the subtraction property of equality.

The property states that if you subtract the same amount from both sides of an equation the equation remains the same.
