Answer:
4.
l=22cm
b:16cm
h:10cm
surface area =2(lb+bh+lh)=2(22*16+16*10+22*10)
=1464cm²
5.
a=2.5dm
area cubical soda cracker box=6a²=6*2.5²=37.5dm²
6.
r=1.5dm
area of ball=4πr²=4π×1.5²=28.27dm² per ball
for 10 bal =28.27×10=282.6dm²
To answer this question you will need to calculate what 70% of the value of the house is because this is what the tax is based on.
0.7 x $132000 = $92400 tax basis
They pay $80 per $1000 in tax basis, so $92400 would be 92.4 groups of $1000.
$80 x 92.4 = $7424 in taxes based on an 80 mills tax rate.
The confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
<h3><u>Confidence interval</u></h3>
To determine what is the 92% confidence interval for the population mean of drivers that do not like driving at night, the following calculation must be performed:
- 1500 = 100
- 900 =X
- 900 x 100 / 1500 = X
- 60 = X
- 60 x 0.92 = 55.2
- 60 x 1.08 = 64.8
Therefore, the confidence interval for the mean population of drivers who do not like driving at night is 57.79% - 62.21%.
