Emanuel surveyed a random sample of 505050 subscribers to Auto Wheel magazine about the number of cars that they own. Of the sub

Anna [14]

Answer:

The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102

Step-by-step explanation:

We can build an estimate from a sample, and this estimate will be the best estimate for the proportion of the population.

Sample:

50 subscribers

15 own fewer than 2 vehicles

Proportion:

15/50 = 0.3 = 30% own fewer than 2 vehicles.

Based on the data, what is the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles?

340 subscribers

The most reasonable estimate for this number is 0.3*340.

0.3*340 = 102

The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102

Drainage tubing comes in large rolls. At your hardware store, you cut tubing to the lengths the customers want. You also provide

MrRa [10]

Answer: $\frac{1}{36}\pi L$

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

$V=\pi r^2h$

Where "r" is the radius and "h" is the height.

Make the conversion from inches to feet. Since $1\ ft=12\ in$ ,you get:

$(2\ in)(\frac{1\ ft}{12\ in})=\frac{1}{6}\ ft$

So in this case you can identify that:

$r=\frac{1}{6}\\\\h=L$

Then, substituting them into the formula and simplifying you get:

$V=\pi(\frac{1}{6})^2L\\\\V=\frac{1}{36}\pi L$

Therefore, the expression for the volume of L feet of drainage tubing, in cubic feet is:

$\frac{1}{36}\pi L$

Erica earns $11.00 per hour and works a 40 - hour workweek. She is paid time and a half for every hour worked over 40 hours duri

GREYUIT [131]

Base pay = $11 x 40 or $440

$605 - 440 = $165 in overtime
Overtime is 1.5 (1 and a half times) her usual salary

11 x 1.5 = $16.50

$165 ÷ $16.50 = 10 hours of overtime.

What is the perimeter of the trapezoid with vertices Q(8, 8), R(14, 16), S(20, 16), and T(22, 8)? Round to the nearest hundredth

uysha [10]

Answer:

The perimeter of the trapezoid is $38.25\ units$

Step-by-step explanation:

we know that

The perimeter of the trapezoid is the sum of its four side lengths

In this problem

$P=QR+RS+ST+QT$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$Q(8, 8), R(14, 16), S(20, 16),T(22, 8)$

step 1

Find the distance QR

$Q(8, 8), R(14, 16)$

substitute the values in the formula

$d=\sqrt{(16-8)^{2}+(14-8)^{2}}$

$d=\sqrt{(8)^{2}+(6)^{2}}$

$d=\sqrt{100}$

$QR=10\ units$

step 2

Find the distance RS

$R(14, 16), S(20, 16)$

substitute the values in the formula

$d=\sqrt{(16-16)^{2}+(20-14)^{2}}$

$d=\sqrt{(0)^{2}+(6)^{2}}$

$d=\sqrt{36}$

$RS=6\ units$

step 3

Find the distance ST

$S(20, 16),T(22, 8)$

substitute the values in the formula

$d=\sqrt{(8-16)^{2}+(22-20)^{2}}$

$d=\sqrt{(-8)^{2}+(2)^{2}}$

$d=\sqrt{68}$

$ST=8.25\ units$

step 4

Find the distance QT

$Q(8, 8),T(22, 8)$

substitute the values in the formula

$d=\sqrt{(8-8)^{2}+(22-8)^{2}}$

$d=\sqrt{(0)^{2}+(14)^{2}}$

$d=\sqrt{196}$

$QT=14\ units$

step 5

Find the perimeter

$P=10+6+8.25+14=38.25\ units$
