Answer:

8 1/8 units ^3

Step-by-step explanation:

The volume is given by

V = Bh where B is the area of the base and h is the height

V = 16 1/4 * 1/2

Changing to an improper fraction

V = ( 4*14+1)/4 * 1/2

  = (65/4) * 1/2

  = 65/8

Changing back to a mixed number

  = 8 1/8

Answer:

The volume can be found by multiplying these two numbers, which is

65/4 x 1/2

65/8 units^3

Let me know if this helps!

nasty-shy [4]

First convert the equation in the form of <em>y= mx + </em><em>c</em>

The equation will be like = y = 6x-5

value of m = 6

The slope of perpendicular line will be = -1/m = -1/6

A production process is checked periodically by a quality control inspector. the inspector selects simple random samples of 30 f
777dan777 [17]

Answer:

Population Mean = 2.0

Population Standard deviation = 0.03

Step-by-step explanation:

We are given that the inspector selects simple random samples of 30 finished products and computes the sample mean product weight.

Also, test results over a long period of time show that 5% of the values are over 2.1 pounds and 5% are under 1.9 pounds.

Now, mean of the population is given the average of two extreme boundaries because mean lies exactly in the middle of the distribution.

So,   Mean, \mu = \frac{1.9+2.1}{2} = 2.0

Therefore, mean for the population of products produced with this process is 2.

Since, we are given that 5% of the values are under 1.9 pounds so we will calculate the z score value corresponding to a probability of 5% i.e.

             z = -1.6449 {from z % table}

We know that z formula is given by ;  

                Z = \frac{Xbar - \mu}{\frac{\sigma}{\sqrt{n} } } ~ N(0,1)

              -1.6449 = \frac{1.9 - 2.0}{\frac{\sigma}{\sqrt{n} } }     ⇒  \frac{\sigma}{\sqrt{n} }  = \frac{-0.1}{-1.6449}  

                                           ⇒ \sigma = 0.0608 * \sqrt{30}  {as sample size is given 30}

                                           ⇒ \sigma = 0.03 .

Therefore, Standard deviation for the population of products produced with this process is 0.0333.

A circle has a circumference of 452.16452.16 units. What is the radius of the circle?
ella [17]

Answer:

72 units

Step-by-step explanation:

A circle has a circumference of 452.16

The formula for circumference of circle = 2\pi r

Where r is the radius of circle

The approximate value of pi = 3.14

Given circumference C= 452.16

C = 2\pi r

452.16 = 2(3.14)r

452.16 = (6.28)r

Divide both sides by 6.28

r = 72

So radius of the circle 72 units
