Answer:
Cross section
Step-by-step explanation:
When we slice a three-dimensional object, we expose new faces that are two dimensional. The two-dimensional face is a cross section.
Answer:
888
Step-by-step explanation:
let the number be n then divide by 8 , that is
now add 8 to this
+ 8 and finally multiply this by 8 and equate to 952
8( + 8) = 952 ( divide both sides by 8 )
+ 8 = 119 ( subtract 8 from both sides )
= 111 ( multiply both sides by 8 to clear the fraction )
n = 888
the number chosen was 888
A point estimate of the mean is a number that is used to approximate the true value of said population parameter.
To find the point estimate of the mean we will use the associated sample parameter X-bar.
Since Xbar is an unbiased estimator of μ, then:
μ_X-bar = μ.
X-bar = 16.6
So:
The estimate of population mean = X-bar = 16.6

Convert to improper fractions first:
15/8 x 7/3
Cross- cancel common factor (3):
5/8 x7/1
Multiply fractions:
5x7 / 8x1
Solve:
35/8
Simplify:
4 3/8
Step-by-step explanation:
angle MRP
angle PRS=angle RPN (alternate angles)
2x+x+x+78°=180°(sum of angles of a triangle)
4x+78°=180°
4x=180°-78°
4x=102°
4x/4=102°/4
x=25.5
