Sav [38]

Answer: 86.64%

Step-by-step explanation:

Let x be a random variable that represents the diameter of metal samples.

Given : Population mean : \mu=10

Standard deviation: s=0.50

Specified tolerance on the diameter is 0.75 mm.

i.e. range of diameter = 10-0.75< x <10+0.75 = 9.25< x< 10.75

Formula to find the z-score corresponds to x: z=\dfrac{x-\mu}{s}

At x= 0.75,  z=\dfrac{9.25-10}{0.50}=-1.5

z=\dfrac{9.25-10}{0.50}=1.5

Using standard normal table for z-value,

P-value : p(-1.5

∴ Percentage of samples manufactured using this process satisfy the tolerance specification = 86.64%

What's the error? Jerry says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides t
disa [49]
The quick way to dispute something like this is to simply do the calculation and then create a ratio. 

Cube One (Large Cube)
The formula for a cube is V = e^3 
e = the measurement of an edge. In this case.
e = 10 cm
V = e^3
V = 10^3 = 10*10*10
V = 1000 cm^3

Cube 2 (Small Cube)
V = e^3
e = 5 cm
V = 5*5*5
V = 125 cm^3

Ratio
Large Cube / Small Cube = 1000 / 125 = 8/1.

The difference in size is 8 to 1 not 2 to 1.

Explanation
He's right if he sticks to one side. The ratio of one side of the large cube to the small one is 2 to 1. But once you put that into the formula for volume, three sides are multiplied together and that 2 shows up everytime you multiply the sides together.

What is the value of x in this diagram?
mixas84 [53]

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
