Answer:

The rectangle for the porch and most of the house is 15+ 10 = 25 by 30

25 x 30 = 750

The top triangles are 5 x 5 = 25. We don't need to divide because there are two triangles

The 5 and 5 from the triangle can subtract the bottom 30 to find the length of the rectangle

30-5-5=20 x from the height of the triangle = 100

100+750+25=875

hope this helps. Your answer is 875

Of all the people applying for a certain job 75% are qualified and 25% are not. The personnel manager claims that she approves q

Gwar [14]

Answer:

The probability is: 0.8889.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Approved

Event B: Qualified

Probability of a person being approved:

80% of 75%(qualified)

30% of 25%(not qualified). So

$P(A) = 0.8*0.75 + 0.3*0.25 = 0.675$

Probability of a person being approved and being qualified:

80% of 75%, so:

$P(A \cap B) = 0.8*0.75$

Find the probability that a person is qualified if he or she was approved by the manager.

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.8*0.75}{0.675} = 0.8889$

The probability is: 0.8889.

I need help on this equastion.

Anna [14]

Answer:

x = 10

Step-by-step explanation:

$3 + \frac{x}{5} = 5 \\ = > \frac{15}{5} + \frac{x}{5} = 5 \\ = > \frac{15 + x}{5} = 5 \\ = > 15 + x = 5 \times 5 \\ = > 15 + x = 25 \\ = > x = 25 - 15 \\ = > x = 10$
