Answer:
A (0,-6)
Step-by-step explanation:
Y intercept is the point where x = 0
y = 4(0) - 6 = -6
(0,-6)
Answer:
1. 5.25 - 5= 0.25
2. 5.5 - 4 = 1.5
Step-by-step explanation:
<h3>Find the mean: </h3>
- Add all values
- Divide by how many numbers there are
Last week:
2 + 3 + 3 + 3 + 4 + 4 + 7 + 7 + 7 + 7 + 8 + 8 = 63
63/12 = 5.25
This week:
2 + 2 + 2 + 3 + 3 + 4 + 4 + 6 + 8 + 8 + 9 + 9 = 60
60/12 = 5
<h3>Last week mean - This week mean: </h3>
Mean of strikes last week - Mean of strikes this week =
5.25 - 5 = 0.25
<h3>Find the Median: </h3>
- Put all values in order
- Find the middle value (If there are two numbers in the middle then find the mean of the two values)
Last week:
2 3 3 3 4 <u>4 7</u> 7 7 7 8 8
4 + 7 = 11
11/ 2 = 5.5
This week:
2 2 2 3 3 <u>4 4 </u> 6 8 8 9 9
4 + 4 = 8
8/2 = 4
<h3>
Last week median - this week median: </h3>
5.5 - 4 = 1.5

Answer: 100
500 Is 100%
500 ÷ 100 = 5
5 Is 1%
5 x 20 = 100
100 Is 20%
Answer: 414.48
Step-by-step explanation:
r: the radius of the base
h: height
The volume of a cone is given by:
V = π ∙ r2 ∙ h / 3,
where π ∙ r2 is the base area of the cone.
π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.
