Answer:
C = 20
Step-by-step explanation:
What happens if simultaneous Equations have two of the same variable like below? How would I solve it?
6A + 4B + 5C = 390
6A + 4B + 5.75C = 405
Step 1
We solve for C first
6A + 4B + 5C = 390....Equation 1
6A + 4B + 5.75C = 405... Equation 2
We substract Equation 1 from Equation 2
0.75C = 15
C = 15/0.75
C = 20
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.
I think the answer is (x,y)=(3,2)
Answer:
a. should not be rejected
Step-by-step explanation:
H0 : σ² = 0.003
H1 : σ² > 0.003
We obtain the test statistic :
χ² = [(n - 1) * s²] ÷ σ²
s = sample standard deviation = 0.06
n = sample size = 26
σ² = 0.003
χ² = [(26 - 1) * 0.06²] ÷ 0.003
χ² = (25 * 0.06²) / 0.003
χ² = 30
Using the Pvalue from χ² calculator :
Pvalue = 0.2242
Using α = 0.05
Pvalue > α; we fail to reject the Null
