Answer:
Area of the hub = 470.42 cm² (Approx.)
Step-by-step explanation:
Missing information;
Circumference of the hub = 76.87 cm
Value of π = 3.14
Find:
Area of the hub
Computation:
Circumference of the hub = Circumference of circle
2πr = 76.87
2(3.14)r = 76.87
6.28r = 76.87
Radius of hub = 12.24 cm
Area of the hub = Area of circle
Area of the hub = πr²
Area of the hub = (3.14)(12.24)²
Area of the hub = (3.14)(149.8176)
Area of the hub = 470.42 cm² (Approx.)
Yes, If the circumference of the hub cap were smaller, Area will be small too.
Answer:
1. 2.9
2. 51 inches
3. (if you can send a picture of the question, I can tell you an answer.
Step-by-step explanation:
for number 1:
You have to add the scores on the left and divide it by the total. What I did was multiply each number on the right with it's pair and added it up. I got 111. Afterwards, I totalled the number of students (I got 38) and divided the scores by the number of students to get 2.9.
for number 2:
You do the same thing as number one but instead of multiplying pairs, you add the heights. I got 255 and then divided it by 5 total heights. I got 51 inches.
for number 3: I didn't get the graph to tell you the answer but I can tell you what everything means.
Symmetric means that both sides of the graph are equal and if you fold the graph in half horizontally, you should get the same shape.
Gaps are where you see blanks in the graph where the data gets cut off and then has stats again.
Cluster is when a huge amount of data is gathered in one area.
Peak is where the data (x-axis) reaches it's highest point (highest y-axis point).

Answer:
(a) One count is only 7, and the guidelines for using the large-sample method call for all counts to be at least 10.
Step-by-step explanation:
Attached is the solution to b and c
Answer-
The number is 5
Explanation-
let the number be x
according to the condition
2x-(x-7)= 12
2x-x+7=12
x+7=12
x+7-7=12-7
x=5
therefore the required number is 5
