Answer:
Red
Step-by-step explanation:
Blue: $127.75 ÷ 7 = $18.25
Red: $73.52 ÷ 4 = $18.38
<u>Blue's cost per chair:</u> $18.25
<u>Red's cost per chair:</u> $18.38
Given:
The height of a right cone = 14 in
Base diameter = 17 in
To find:
The diagram of the cone and its lateral surface area.
Solution:
(a)
The diagram of a right cone with height 14 in and base diameter of 17 in is shown below.
Diagram is not to scale.
(b)
We know that lateral surface of the cone is

...(i)
Where, r is the base radius, h is vertical height and l is the slant height of the cone.
Base radius of the cone = 


Now,
Putting r=8.5, h=14 and π=3.14 in (i), we get





Therefore, the lateral surface area of the cone is 437 sq. inches.
Answer:
40.75 (40 3/4) Miles per hour
Step-by-step explanation:
(2/3) (3/2) = 1, so
30.5 x (3/2) = 40.75
Answer:
6.67meters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid = Length × Width × Height
From the question
Volume = 200m³
Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m
To find the height of the pyramid = Volume/Length × Width
Height = 200m³/ 6m × 5m
Height = 6.67m
Height of the rectangular pyramid in meters = 6.67 m
Answer: (D) you reject it 5% of the time
Step-by-step explanation:
- In hypothesis testing ,Type 1 error is the situation when the null hypothesis is true but we reject it.
Given : A test of hypothesis has a Type I error probability of 0.05
Which can be written as 5%.
It means that if null hypothesis is true, <u>you reject it 5% of the time.</u>
