Answer:

m=665+4h

Step-by-step explanation:

Profits of the local bakery is given by

P=m-(250+4h)

where

m = Amount of money to be received

P = Profit

h = Number of hours worked

Now P = $415

So,

P+(250+4h)=m\\\Rightarrow m=P+250+4h\\\Rightarrow m=415+250+4h\\\Rightarrow m=665+4h

The equation to calculate the amount of money, m, the bakery should receive if the desired profit is $415 is m=665+4h.

A ladder is leaning against the side of a building. The
cupoosta [38]

Answer:

16 ft

Step-by-step explanation:

Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:

c = √( a² + b²)

In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.

c² = a² + b²

a² = c² - b²

a = √( c² - b² )

a = √( 20² - 12² )

a = 16

The unit is in ft.

Correct me if I'm wrong. I hope it helps.

Which of the following is NOT a property of a kite?
jonny [76]
The correct answer is <span>C. Diagonals bisect each other

That is not a property of a kite because its diagonals intersect at right angles. Diagonals that bisect each other appear on things such as rectangles.  </span>

A diagnostic test for a disease is such that it (correctly) detects the disease in 90% of the individuals who actually have the
mart [117]

Answer:

0.1552

Step-by-step explanation:

Hi!

Give a random person, lets call:

D = the person has the disease

¬D = the person doesnt have the disease

T = the test on this person is positive (detects the disease)

¬T = the test on this person is negative

We are give the conditional probabilities:

P(T | D) = 0.9

P(¬T | ¬D) = 0.9

P(D) = 0.02

From those we know that:

P(T | ¬D) = 0.1

P(¬T | D) = 0.1

We must find P(D | T). For that we use Bayes theorem:

P(D|T) = \frac{ P(T|D)P(D)}{P(T|D)P(D) +P(T| \neg D)P(\neg D) }

P(D | T) = \frac{0.9*0.02}{0.9*0.02 + 0.1*0.98} = 0.1552
