1/8 the fraction?
two eighths = 2/8=1/4
Answer:
The approximate probability that more than 360 of these people will be against increasing taxes is P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
The right answer is B.
Step-by-step explanation:
According to the given data we have the following:
sample size, h=600
probability against increase tax p=0.45
The probability that in a sample of 600 people, more that 360 people will be against increasing taxes.
We find that P(P>360/600)=P(P>0.6)
The sample proposition of p is approximately normally distributed mith mean p=0.45
standard deviation σ=√P(1-P)/n=√0.45(1-0.45)/600
If x≅N(u,σ∧∧-2), then z=(x-u)/σ≅N(0,1)
Now, P(P>0.6)=P(<u>P-P</u> > <u>0.6-0.45)</u>
σ √0.45*0.55/600
=P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600

Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft
