When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram
Answer:
Step-by-step explanation:
Given that X the time to complete a standardized exam in the BYU-Idaho Testing Center is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
We have 68 rule as 2/3 of total would lie within 1 std deviation, and 95 rule as nearly 95% lie within 2 std deviations from the mean.
We have std deviation = 10
Hence 2 std deviations from the mean
= Mean ±2 std deviations
=
±20
= 
Below 50, 0.25 or 2.5% would complete the exam.
Answer:
Center of the Sphere is a fixed point in its interior which is equidistant from each point on sphere. Option 1 is not right because it says center is line segment. Option 3 is right as it says it is fixed and equidistant from point of surface.
Step-by-step explanation:
1 The center of a sphere is
2 a line segment from the center point to the surface of the sphere.
3 a fixed point equidistant from all points on the surface of the sphere.
4 a three-dimensional circle in which all points are equidistant from a fixed point.
5 the same as the base of the sphere
nvm too late :D
the answer is number 3
First, the rectangle:
We have the measurements of a length of 4, and width of 2. The area of a rectangle is Length times Width, therefore:
4x2=8 ft squared for the rectangle.
Now the Triangle:
We see that the whole left side is 4ft, and that the rectangle's width is 2ft; therefore, the left side of the triangle is 2 ft (4-2).
The area of a triangle is 1/2Base times Height. The base is 4, and the height is 2; therefore:
1/2x4x2=4 ft squared.
Now we add our areas for the total:
4+8=12 ft squared
I hope this Helps!
