Answer: the area of a figure is 85.13 in²

Step-by-step explanation:

The area of a figure S consists of the area of a semicircle S₁ and the area of a parallelogram S₂

$\displaystyle\\S_1=\frac{\pi D^2}{4*2} \\\\S_1=\frac{\pi (8)^2}{8} \\\\S_1=\frac{64\pi }{8} \\\\S_1=8\pi \\\\S_1\approx25.13\ in^2\\\\S_2=10*6\\\\S_2=60\ in^2\\\\Thus,\\\\S=25.13+60\\\\S=85.13\ in^2$

Answer:

b) yes

The manufacturer has the right to state that the light bulbs last on average 400 hours

Step-by-step explanation:

Explanation:-

Given sample size 'n' = 64

Given standard deviation of the Population (σ)=100

Mean of the sample (x⁻) = 350 hours

95% of confidence interval is determined by

$(x^{-} -Z_{0.95} \frac{S.D}{\sqrt{n} } , x^{-} +Z_{0.95} \frac{S.D}{\sqrt{n} } )$

( $(350 -1.96 \frac{100}{\sqrt{64} } , 350+1.96\frac{100}{\sqrt{64} } )$

(350-24.5 , 350+24.5)

(325.5 , 374.5)

Conclusion:-

Yes

The manufacturer has the right to state that the light bulbs last on average 400 hours
