Answer:
The chart A is correct
Pareto Chart
Step-by-step explanation:
Given chart is missing (Attached)
Find:
- Which chart represents the correct data.
- What other chart can be used to express the given data
Solution:
- Use the given values for each color and compare with the three charts A,B and C given.
For Blue = A (12) , B(12) , C(11)
For Green = A(7) , B(13) , C(12)
- Hence, The chart A is correct.
- Any other chart which can correctly express the information given should be a chart that uses bars or frequency to expresses the percentages. Pareto Chart expresses both bars and line chart(curve) to express the frequency of the data.
Answer:
It's y=3x
Step-by-step explanation:
The y-intercept is 0, it's direct variation. The slope(rise/run) is 3.
there are 4 aces and 4 9's for a total of 8 cards
there is a total of 52 cards
so 9/52 is the probability
Answer:
1. 
3. 
(undefined slope)
5. 
7. 
Step-by-step explanation:
slope (m)
rate of change (r)
1. m = 
3. m = 
(undefined slope)
5. m = 
7. r =

Answer:
The cylinder is cheaper to make because it has less surface area.
Step-by-step explanation:
In order to find the surface area of a cylinder, you do 2πrh+2πr²
We need the radius, which is half of the diameter, so then we have 2π(3·12)+2π·3² which gets us 282.72
We also need the surface area of the rectangular prism which we can get by 7x4 + 7x4 + 12x7 + 12x7 + 12x4 + 12x4 which gets us 320
282.72 < 320
