Answer:
A, B
Step-by-step explanation:
The flag has 180° rotational symmetry, so rotation by that amount around the center will map either triangle to the other.
The legs of the triangles are different lengths, so no rotation of 90° or 270° can map one to the other.
The two choices shown below are applicable.
Answer:
x = 13/7 or x = 1 6/7
Step-by-step explanation:
V=(pi)r 2 h. ( volume is equal to pi times radius squared times height). V= pi 2^2 x8
Pi times 4times8= pi times 32. Put in a calculator pi times 32 and you get 100.5 cubic inches ( I haven’t done this in awhile but I think this is correct)
Answer: 40.68 %
Step-by-step explanation:
We need to find the interval between the values 0.2 and 2.2
0.2 ≤ z ≤ 2.2
Since in the standardized normal curve the mean 5.8 will be 0
Area for z values ≥ 0.2 ⇒ 0.0793 and area for z ≤ 2.2
area between 0 and 0.2 is 0.0793 ; and area between 0 to 2.2 is 0.4861
this last value includes the previous value at the left of z = 0.2
As we are looking for participants in the interval 0.2 ≤ z ≤ 2.2 we need to subtract areas 0.4861 - 0.0793 = 0.4068 express in % is 40.68 %
