Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 138
Average = 32.6 inch
Population variance,
We have to find a point estimate for the population variance of the height.
The point estimate for the population variance is the population variance itself.
Thus, the point estimate of population variance is the population variance that is 2.8.
Answer:
Step-by-step explanation:
0.5x=208.8
x=417.6
Answer:
9x+14y
Step-by-step explanation:
First Multiply the number outside of the brackets with the numbers inside the brackets. Ex:3 x 3x and 3 x -y
17y-2x+3(3x-y)+2x
That should get you to this.
17y-2x+9x-3y+2x
Next combine like terms.
14y+9x
Hope this helps!
In a triangular prism, B usually stand for the triangular base of the prism. It is the area of the triangle.
Area of a right triangle = ab/2
a = long leg ; b = short leg
Given measures are:
a = 4 yd ; b = 3 yd
A = (4 yd * 3 yd)/2 = 12 yd² / 2 = 6 yd² is the value of B.
the hypotenuse is 5 yd but it is not needed to get the area of the right triangle base. 7 yd is the measure of the height of the triangular prism.
