Nuetrik [128]

Answer:

Unit rate is 3 ounce of water per ounce of mix

Step-by-step explanation:

you combine 12 ounces of mix with 36 ounces of water.

12 ounces of mix for 36 ounces of water

For unit we need to find the ounces of water for 1 ounce of mix

12 ounces of mix for 36 ounces of water

so 1 ounces of mix for 36 / 12 = 3 ounces of water

3 ounces of water for 1 ounce of mix

Hence, 3 ounces of water per ounce of juice

The mean number of accidents a week at a company is 6.4 with a standard deviation of 1.5. What proportion of weeks would you exp

julia-pushkina [17]

Answer:

0.17619

Step-by-step explanation:

We solve using z score formula

= z = (x-μ)/σ,

where x is the raw score = 5 accidents

μ is the population mean = 6.4 accidents

σ is the population standard deviation = 1.5

z = 5 - 6.4/1.5

= -1.4/1.5

= -0.93333

Approximately to 2 decimal places = -0.93

Determining the probability value from Z-Table:

P(x< 5) = P(z = -0.93) = 0.17619

Converting this to percentage =

The probability of weeks you would expect to have less than 5 accidents is

0.17619

We are asked in the question:

What proportion of weeks would you expect to have less than 5 accidents?

Proportion is also the same as:

Therefore, the proportion of weeks that you expect to have less than 5 accidents = 0.17619

To find the radius of the circular storage shed, you will use the formula for finding the volume of a cone (V=1/3 x pi x r^2 x h, where r is the radius and h is the height.

You will substitute in the information you know and then solve for the radius(r).

Please see the attached picture for the steps necessary to get an approximate radius of 2.02 ft as the radius.
