If P(A) = .80, P(B) = .65, and P(A ∩ B) = .78, then P(B | A) =

Answers

Answer:

P(B | A) = 1.2

Step-by-step explanation:

Given

P(A) = .80P(B) = .65P(A ∩ B) = .78

To determine

P(B | A) = ?

Using the formula

P(B | A) = P(A ∩ B) / P(B)

= .78 / .65

= 1.2

Therefore,

P(B | A) = 1.2

Answers

Answer:

Step-by-step explanation:

Given function is,

f(x) = [tex]x\sqrt{x}[/tex]

We can rewrite this function as,

f(x) = [tex]x^{\frac{3}{2}}[/tex]

a). Domain of the function is [0, ∞)

Derivative of the function in this domain,

f'(x) = [tex]\frac{3}{2}x^{(\frac{3}{2}-1)}[/tex]

= [tex]\frac{3}{2}x^{\frac{1}{2}}[/tex]

Since, f'(x) > 0 in the interval [0, ∞)

Function is increasing in the interval [0, ∞)

b). For local maxima and local minima,

Second derivative of the function,

f"(x) = [tex]\frac{3}{2}(\frac{1}{2})x^{\frac{1}{2}-1}[/tex]

= [tex]\frac{3}{4}x^{-\frac{1}{2}}[/tex] > 0

So the function should have a local minima.

But the function is continuous in the interval x ≥ 0,

There is no local minima (only absolute minima).

c). Since, second derivative is undefined at x = 0,

There are no inflection points.

d). Since, f"(x) > 0 in the interval [0, ∞)

Concavity of the curve is UPWARDS.

Answer: x=59, angle 1= 44˚, angle 2= 136˚

Step by step explanation:

Linear pairs add to make 180˚.

So angle 1 + angle 2= 180˚

Therefore x-15+x+77= 180

Add the x’s to get 2x
And then -15+77 to get 62.

So 2x+62=180
Subtract 62 to get 2x=118
Then divide by 2 to get x=59

Then substitute the x value into the angle equations

So angle 1 will be 59-15 which is 44˚
And angle 2 will be 59+77 which is 136˚

8x-6y=36
solve the linear equation

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

The shadow of a 60 foot pole is a 100 feet long. What is the angle of evaluation from the end of the shadow to the top of the pole?

Answers

Answer:

The angle is approximately [tex]31^{o}[/tex].

Step-by-step explanation:

The description i the given question can be represented with the sides of a right angled triangle.

Applying the appropriate trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

In the question, opposite side = 60 feet, and adjacent side = 100 feet.

Tan θ = [tex]\frac{60}{100}[/tex]

= 0.6

θ = [tex]Tan^{-1}[/tex] 0.6

= [tex]30.964^{o}[/tex]

θ = [tex]31^{o}[/tex]

The angle of elevation from the end of the shadow to the top of the pole is [tex]31^{o}[/tex].

Their plans indicate that each unit of the new product requires the following: Direct Material 4 lb. of a material costing $7 per lb. Direct labor 2 hrs. of a metal former's time at $15.40 per hr. 0.6 hr. of an assembler's time at $11.20 per hr. Major items of production overhead would be annual rent of $65,044 for a factory building, $40,124 rent for machinery, and $30,380 of indirect material. Other production overhead is estimated to be $326,592. Selling expenses are an estimated 30% of total sales, and non-factory administrative expenses are 20% of total sales.The consensus at Innovation is that during 2016 10,000 units of product should be produced for selling and another 2.000 units should be produced for the next years beginning inventory. Also, an extra 3,000 pounds of material will be purchased as beginning inventory for the next year. Because of the nature of the manufacturing process, all units started must be completed, so work in process inventories are negligible.Required Incorporate the above data into a schedule of estimated total manufacturing costs and compute the unit production cost for 2016.
