For number one, the answer will be C because the ratio between the side and the perimeter of the Pentagon will be 1/5 or 2/10 or 3/15. For number 2, we know that the Pentagon had 5 sides, and the side of it is 8, so the perimeter of this Pentagon will be 8+8+8+8+8 or 40 inches, which is C. Hope it help!

Answer:

x=Sin-1(0.470584)

x=28.1°

Step-by-step explanation:

Sin90°/17 =Sin x°/8

0.058823 = Sin x°/8

8(0.058823)=Sin x°

x°=Sin-1(0.470584)

x=28.1°

The probability that a randomly selected person has high blood pressure (the event H) is P(H) = 0.3 and the probability that a r

Elena L [17]

Answer:

The probability of choosing a person with BP who is also a runner is 2/3.

Step-by-step explanation:

According to the given data:

P( Selecting a person with high blood pressure ) = 0.3

or, P(H) = 0.3

P( Selecting a person who is a Runner ) = 0.4

or, P(R) = 0.4

Now, P( Randomly Selecting a person who has high BP and is a runner) = 0.2

⇒ P(H∩ R) = 0.2

Now, we need to find the P(randomly selected person is a runner and has already has high BP)

or we need to find: P(R/H)

now, by BAYES THEOREM:

$P(R/H) = \frac{P(R\cap H)}{P(H)}$

$\implies P(R/H) = \frac{0.2}{0.3 } = \frac{2}{3}$

Hence, the probability of choosing a person with BP who is also a runner is 2/3.

Points Q and R are midpoints of the sides of triangle ABC.

givi [52]

we know that

In the figure triangle ABC and triangle AQR are similar triangles

so

by proportion

$\frac{QR}{AQ} =\frac{BC}{AB} \\ \\ \frac{2p+3}{4p} =\frac{6p-4}{8p} \\ \\ 2*(2p+3)=(6p-4)\\ \\ 4p+6=6p-4\\ \\ 6p-4p=6+4\\ \\ 2p=10\\ \\ p=5$

$AQ=4p\\ AQ=4*5\\ AQ=20\ units$

therefore

<u>the answer is</u>

AQ is $20\ units$
