Answer:
I think the answer would be 1
Step-by-step explanation:
Width=x-6
lenght=x
Perimeter of a parallelogram=2(lenght)+2(width)
Data:
Perimeter=60 m
Therefore:
2(x)+2(x-6)=60
2x+2x-12=60
4x=60+12
4x=72
x=72/4
x=18
Width=x-6=18-6=12
Lenght=x=18
Answer: the lenght would be 18 m, and the width 12 m
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
Answer: A is 200 + 45h = c B is $425
Step-by-step explanation:
45 * 5 = 225 Now add 200. 225 + 200 = $425
