A company charting its profits notices that the relationship between the number of units sold, x, and the profit, P, is linear.
scoundrel [369]

Answer:

P(x) = 58x - 8,500

Step-by-step explanation:

The profit function can be modeled based on the two given points of format (P, x) that are ($1360, 170) and ($4260, 220). The slope of the function is:

m=\frac{4,260-1,360}{220-170}\\ m=58

Applying the general form of a linear equation, the profit function is:

P-P_0 = m*(x-x_0)\\P - 1,360=58*(x-170)\\P(x) = 58x -8,500

The profit as a function of units sold is P(x) = 58x - 8,500.

A manufacturer knows that their items have a normally distributed length, with a mean of 16.2 inches, and standard deviation of
statuscvo [17]

Answer:

57.926%

Step-by-step explanation:

Calculation for the probability that it is less than

16.4 inches long

Using this formula

z = (X - μ) / σ

Where,

X represent Date=16.4

μ represent Mean=16.2

σ represent Standard deviation=0.9 inches

Let plug in the formula

z = (16.4 - 16.2) /0.9 inches

z=0.2/0.9 inches

z = 0.2

Using Z-score table to find the area of 0.2

z=0.57926*100

z=57.926%

Therefore the probability that it is less than

16.4 inches long is 57.926%

Can you please help me out with a question
uranmaximum [27]

ANSWER

\begin{gathered} \text{Radius}=13.5\text{ yards} \\ \text{Diameter=27 yards} \end{gathered}

EXPLANATION

We want to find the radius and diameter of a circle given that its circumference is 84.823 yards.

The circumference of a circle is given as:

C=2\pi r

where r = radius

Therefore, the radius is:

\begin{gathered} 84.823=2\cdot\pi\cdot r \\ \Rightarrow r=\frac{84.823}{2\cdot\pi} \\ r=13.5\text{ yards} \end{gathered}

Diameter is twice the radius.

Therefore, the diameter is:

\begin{gathered} D=2\cdot r \\ D=2\cdot13.5 \\ D=27\text{ yards} \end{gathered}
