The diameter of the wheels on your car is 25 inches. You are going to drive 458 miles today. Each of your wheels is going to tur

Kipish [7]

d = Diameter of wheels = 25 inches

s = Distance to be traveled by the wheels = 458 miles

Converting the miles to inches

$s=458\times 5280\times 12=29018880\ \text{inches}$

The distance traveled by the wheels in rotation is the circumference

$D=\pi d\\\Rightarrow D=\pi\times 25$

The number of rotations required to cover the distance would be

$\dfrac{s}{D}\\ =\dfrac{29018880}{\pi\times 25}\\ =369479.855599$

$1$ rotation is $360^{\circ}$ so

$369479.855599\times 360=133012748.016^{\circ}$

The number of rotations to cover the required distance is $133012748.016^{\circ}$

What is the value of the function f(x) = 1.5x + 7.6 when x = 1.1?

dangina [55]

f(x) = 1.5x + 7.6
f(1.1) = 1.5(1.1) + 7.6
f(1.1) = 1.65 + 7.6
f(1.1) = 9.25

Find the volume of the rectangular prism. IN in. 4 in. 9-in. 2 I

prisoha [69]

Answer:

V = 36 in³

Step-by-step explanation:

The volume of a rectangular prism is given by the formula V = l × w × h

Here our length is $9\frac{1}{2}$ , our width is 4, and our height is $4\frac{1}{2}$

Plugging in these values to our formula give us $V=(9\frac{1}{2})(4)(4\frac{1}{2})= 36$

V = 36 in³

A manufacturer of small appliances purchases plastic handles for coffeepots from an outside vendor. If a handle is cracked, it i

sp2606 [1]

Answer: 119

Step-by-step explanation:

Since the prior estimate of population proportion of defective handles (p) is unknown , so we take p= 0.5

Given : Margin of error : E=0.09

Critical value for 95% confidence interval : $z_{\alpha/2}=1.96$

Required sample size :-

$n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.96}{0.09})^2\\\\=118.567901235\approx119$

Hence, the minimum sample size required = 119

i.e. 119 handles from the shipment should be inspected.
