A citys annual rainfall totals are normally distributed and the probability that the city gets more than 43.2 inches of rain in

a year is given by P(z < 1.5) = 0.0668. If the standard deviation of the city's yearly rainfall total is 1,8 inches, what is the city mean annual rainfall?

What is the equation of the line that passes through the point (5, -2)<br> and has a slope of 6/5
liubo4ka [24]

Answer:

        y + 2 = ⁶/₅(x - 5)     {the point-slope form of the equation}

        y = ⁶/₅x - 8            {the slope-intercept form of the equation}  

         6x - 5y = 40           {the standard form of the equation}

Step-by-step explanation:

The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.

m = ⁶/₅

(5, -2)    ⇒   x₀ = 5,  y₀ = -2

So, the point-slope form of the equation:

y + 2 = ⁶/₅(x - 5)

Therefore:

y + 2 =  ⁶/₅x - 6          {subtract 2 from both sides}

y = ⁶/₅x - 8              ←  the slope-intercept form of the equation

-⁶/₅x + y = - 8                    {multiply both sides by (-5)}

6x - 5y = 40               ←  the standard form of the equation

The least total cost method (LTC) lot-sizing technique calculates the order quantity by comparing the carrying cost and the setu
rewona [7]

Answer:

True

Step-by-step explanation:

The least total cost method is the method in which the total cost of the ordering cost and the total carrying cost is equal among various lot size available.

The order quantity should be choose when the total ordering cost and the total carrying cost equal to each other

The formula to compute the economic order quantity is shown below:

a. The computation of the economic order quantity is shown below:

= \sqrt{\frac{2\times \text{Annual demand}\times \text{Ordering cost}}{\text{Carrying cost}}}

It is always be expressed in units

The formula to compute the ordering cost is

= \frac{Annual\ demand}{Economic\ order\ quantity}\times ordering\ cost\ per\ order

And, the formula to compute the carrying cost is

= \frac{Economic\ order\ quanity}{2}\times carrying\ cost\ per\ unit

Hence, the given statement is true

zavuch27 [327]

Answer:

i) Assigning women at random ensures that the two groups are comparable.

iv) A control group provides a baseline for comparisons to determine treatment effects.

Step-by-step explanation:

(a)

It is pertinent that there two comparable groups. In light of the fact that it will help in making better decisions since there will be some people who have blood pressure as a result of uncontrolled physical characteristics such as anger, positive attitude, lower blood pressure. etc Thus, there is a need to consider two equivalent groups.

(b)

A control group is used as a benchmark for determining the cause and effect of a treatment on a given experimental group. This may be in regard to the social aspect of meeting other individuals involved that make up the physical changes.
