Answer:
Option B. Pentagonal prism
Step-by-step explanation:
Option (A). Cube
Base of a cube is a square.
Option (B). Pentagonal prism
A prism is always defined by its base.
Example: triangular prism, rectangular prism
Therefore, pentagonal prism will have a base in the shape of a pentagon.
Option (C). Triangular prism
Triangular prism will have a triangular base.
Option (D). Rectangular prism
Rectangular prism will have a rectangular base.
Answer:
80
Step-by-step explanation:
Angle VSU = 100. Angles TSU is a linear pair with angle VSU so adding them together equals 180. 180-100=80.
Answer:
Below in bold.
Step-by-step explanation:
x^2 - y^2 = 11
2x^2 + y^2 = 97
From the first equation:
y^2 = x^2 - 11
Substituting in the second equation:
2x^2 + x^2 - 11 = 97
3x^2 = 108
x^2 = 36
x = 6, -6.
Substituting for x in the first equation:
(6)^2 - y^2 = 11
y^2 = 36 - 11 = 25
y = 5, -5.
A. X ~ N(66, 6.25)
b.
![z_{1} =\frac{65-66}{2.5}=-0.4](https://tex.z-dn.net/?f=%20z_%7B1%7D%20%3D%5Cfrac%7B65-66%7D%7B2.5%7D%3D-0.4)
![z_{2} =\frac{69-66}{2.5}=1.2](https://tex.z-dn.net/?f=z_%7B2%7D%20%3D%5Cfrac%7B69-66%7D%7B2.5%7D%3D1.2)
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524
![0.524=\frac{X-66}{2.5}](https://tex.z-dn.net/?f=0.524%3D%5Cfrac%7BX-66%7D%7B2.5%7D)
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
