Answer: A. Contractor A. The probability that both conditions are met is 0.93

Step-by-step explanation:

Probability of two independent events happening can be found by multiplying them.

Probability of A doing the job on time and on budget:

= Probability that job is done on time * Probability it is done on budget

= 0.97 * 0.96

= 0.93

Probability of B doing the job on time and on budget:

= 0.93 * 0.98

= 0.91

<em>Contractor A has the better probability at 0.93 so should be chosen. </em>

What was the price of the car before the sales tax was added?
Illusion [34]

Answer:

One big reason why a car’s total price won’t match the price on its window sticker relates to fees charged by a car dealership and the automaker. For example, although a car may cost $19,995 according to the window sticker, that figure might be the price before the addition of a destination charge, which is a pricy manufacturer’s fee that can add up to $1,000 to the price. A dealer may also charge a documentation fee to prepare the vehicle’s documents for sale, and this figure can sometimes cost as much as $500. There are mandatory government fees too, such as the cost to process the car’s title work or change the registration to your name.

Step-by-step explanation:

Dealer and manufacturer fees usually aren’t the biggest add-ons to a car’s purchase price. The priciest addition typically comes in the form of taxes, since most states levy a sales tax on the entire price of a new or used vehicle. Since sales taxes can range as high as 8-10 percent in some areas, this can easily add thousands of dollars to your vehicle’s purchase price. For example, a $20,000 car purchased in an area with a 7 percent sales tax will cost an extra $1,400 on top of the purchase price, while a $30,000 car bought in a place with a 9 percent sales tax will see a whopping $2,700 price boost before you can drive it home.

A trapezoid has an area of 42 square miles. One base is 4 miles long. The height measures 6 miles. What is the length of the oth
loris [4]

The length of other base of trapezoid is 10 miles

Step-by-step explanation:

The formula for area of trapezoid is:

A=\frac{h}{2}(b_1+b_2)

We know that

A = 42 square miles

b_1 = 4 miles

h = 6 miles

Putting the values

42=\frac{6}{2}(4+b_2)\\42=3(4+b_2)\\42=12+3b_2\\Subtracting\ 12\ from\ both\ sides\\42-12=12+3b_2-12\\3b_2=30\\Dividing\ both\ sides\ by\ 3\\\frac{3b_2}{3}=\frac{30}{3}\\b_2=10\ miles

The length of other base of trapezoid is 10 miles

a freight elevator CAN safely hold no more than 2000 Pound. an elevator operator must take 55lb boxes to a storage área. if he w
BARSIC [14]

Answer:

33 boxes.

Step-by-step explanation:

We have been given that a freight elevator can safely hold no more than 2000 pound. Weight of elevator operator is 165 pound. Weight of each box is 55 pound.

Let n be number of boxes. We will write an inequality as weight of elevator operator and weight of all boxes should be no more than 2000 pound.

55*n+165\leq 2000

Now we will solve our inequality to find number of boxes that could be moved safely at one time.

55*n\leq 2000-165

55*n\leq 1835

n\leq \frac{1835}{55}

n\leq 33.363636

Therefore, 33 boxes can be moved safely at one time.

By finding the size of each exterior angle of a regular polygon with 24 sides, calculate the size of each interior angle of the
Dima020 [189]

We can find the sum of the interior angles of a regular polygon using the formula : (n-2) x 180, where n is the number of sides.

We replaced in : (24-2) x 180 = 3960

So, all the interior angles in this polygon add up to 3960.
-> Each interior angle is equal to 3960 : 24 = 165.
