To find the volume of a triangular pyramid, the formula is:
So we start by finding the area of the base, which is in the shape of a right triangle in this case.
The area of a right triangle is equal to 1/2 x base x height.
We use this area to find the volume.
The volume of the triangular pyramid is 30 cubic feet.
Answer:
69.72 inches.
Step-by-step explanation:
The best point estimate for the average height if males in the United States is...
For large samples, as we have here, the best point estimate is the sample mean. In this question, the sample mean is of 69.72 inches, so the answer is 69.72 inches.
Answer:
41.40
Step-by-step explanation: 36*.15=5.40, 36+5.40=41.40
Answer:
You can toss 4 coins 55 times.
Step-by-step explanation:
Each coin would represent a child as there is an equal chance for a boy and girl, like the chance of heads and tails are equal.
You toss it 55 times as the question asks for 55 trials.
This is an isosceles triangle. The two angles opposite the two equal sides are equal. With this knowledge, we now know that the angles are 61, 61, x.
We also know that the sum of all the angles of a triangle is equal to 180 degrees.
61 + 61 + x = 180.
Combine like terms.
122 + x = 180
Subtract 122 from both sides.
x = 58 degrees
