Answer:
39/64 pounds or 0.61 pounds.
Step-by-step explanation:
According to the image, the heaviest soccer ball weights 15 ounces, and the heaviest baseball weights 5.25. So the difference is:
15 - 5.25 = 9.75 ounces
Since the question is how many more pounds, you have to convert ounces to pounds. 1 pound is equal to 16 ounces, so you have to devide the result by 16.
9.75 / 16 = 39/64 pounds or 0.61 pounds.

What sample size is needed to give a margin of error within ± 13 in estimating a population mean with 99% confidence, assuming a previous sample had s=116
Answer:
The sample size n = 530 samples
Step-by-step explanation:
Margin of Error formula = z × standard deviation/√n
Margin of Error = ± 13
Standard deviation = 116
z = z score of 99% = 2.58
±13 = 2.58 × 116/√n
Cross Multiply
±13 × √n = 2.58× 116
±13 × √n = 299.28
√n = 299.28/±13
√n = ± 23.0215384615
Square both sides
(√n)² = (±23.0215384615)²
n = 529.991233134
Approximately , n = 530 samples
X=109
The polygon has 5 sides which makes it a pentagon
The sum of all of the angles of a pentagon equal 540 degrees.
Add all given angles (431 degrees)
Subtract 431 from 540 and you will get 109 which is X
Point-slope form is y - y1 = m (x + x1)
First you need to find m [slope] by subtract y2 and y1 and divide it by the outcome of x2 - x1
13 - (-9) = 22
-2 - 9 = -11
22/-11 = -2
Plug in the first point (as instructed) into the equation.
y - (-9) = -2 (x - 9)
Simplify the beginning.
y + [9] = [-2] (x + [-9])
