A microchip manufacturer has determined that 6% of the processors they produce are defective. A quality technician performs the

experiment of having each unit from an assembly line inspected until a defective unit is found. When a defective unit is found, the assembly line's production will be stopped. What is the expected value for the number of inspections until a defective unit is found

Answer:

The expected value for the number of inspections until a defective unit is found 17.

Step-by-step explanation:

Percentage of defective microchips = 6%

Let the total number of inspection = x

number of defective microchip = 1

As we know

1/x = 6%

1/x = 0.06

x = 1/ 0.06

x = 16.67 inspections

x = 17 ( rounded off to nearest whole number )

17 inspection is done until the defective microchip is found.

A bicyclist is finishing his repair of a flat tire when a friend rides by with a constant speed of 3.63 m/s. Four seconds later,
castortr0y [4]

From the moment the friend passes the bicyclist, his friend covers a distance over time t of (3.63 m/s)*t.

The bicyclist covers a distance of 1/2*(2.11 m/s^2)*t^2. They meet when these distances are equal:

3.63 t = 1.055 t^2  ==>  1.055 t^2 - 3.63 t = 0

==>  t = 0 s   or   t = 3.44 s

How can u convert a fraction to a decimal if the fraction has a multiple of 10 in the denominator
jonny [76]

So what you would do is you would divide the top number (numerator) by the bottom number (denominator) Like you would normally. So take 3/10 for example you would punch into a calculator 3 divided by 10 or do the work which would be

0.3

and that is how you convert a fraction into a decimal with a denominator of 10

I hope that this helped you. (:

A convertible is traveling at 45 miles per hour, and its wheels have a diameter of 48 inches. How many complete revolutions do t
neonofarm [45]
To answer this question you will need to know how many inches the car travels Per minute.

1. To find this out you will first divide 45 miles by 60 to get the number of miles per minute.

The convertible travels 0.75 mi./min.

2. Next you will convert this number of miles to inches.

There are 63,360 inches per mile.

0.75 x 63360 = 47520 inches per minute.

3. You then need to find the distance the wheel travels in one rotation. You will need to find the circumference of the wheel.

C = pi x d
3.14 x 48
C = 150.72 inches
Each rotation is about 150.72 inches.

4. Finally, divide the total distance traveled in a minute by the circumference(distance of one rotation) to get the total number of rotations in a minute.

47520/150.72 is about 315.3 rotations per minute.
