6 0

Answer:

9. 36.87°, 53.13°, 90°

10. 22.62°, 67.38°, 90°

Step-by-step explanation:

9. From the diagram given with the question.

\tan KLJ =\frac{4y}{3y} =\frac{4}{3}

⇒ ∠ KLJ = \tan^{-1} (\frac{4}{3} )= 53.13 Degree.

Similarly, \tan KJL =\frac{3y}{4y} =\frac{3}{4}  

⇒ ∠ KJL = \tan^{-1} (\frac{3}{4} )= 36.87 Degree.

Therefore, the angles of the Δ KJL will be 36.87°, 53.13°, and 90°. (Answer)

10. From the diagram given with the question.

Similarly,  \tan SQR =\frac{5}{12}

⇒ ∠ SQR = \tan^{-1} (\frac{5}{12} )= 22.62 Degree.

Similarly, \tan QSR =\frac{12}{5}

⇒ ∠ QSR = \tan^{-1} (\frac{12}{5} )= 67.38 Degree.

Therefore, the angles of the Δ SRQ will be 22.62°, 67.38°, and 90°. (Answer)

Solve the equation.<br><br>-4 (y - 2) = 12<br><br>y = ?​
inna [77]
First you distribute what’s outside the parentheses (the -4)

-4•4= -4y
-4•-2= 8

New equation: -4y+8=12

Now you solve like a normal equation
12-8 is 4

New equation: -4y=4

Now divide

Suppose there is a 13.9 % probability that a randomly selected person aged 40 years or older is a jogger. In​ addition, there is
Blababa [14]

Answer:

There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.

It would be unusual to randomly select a person aged 40 years or older who is male and jogs.

Step-by-step explanation:

We have these following probabilities.

A 13.9% probability that a randomly selected person aged 40 years or older is a jogger, so P(A) = 0.13.

In​ addition, there is a 15.6% probability that a randomly selected person aged 40 years or older is male comma given that he or she jogs. I am going to say that P(B) is the probability that is a male. P(B/A) is the probability that the person is a male, given that he/she jogs. So P(B/A) = 0.156

The Bayes theorem states that:

P(B/A) = \frac{P(A \cap B)}{P(A)}

In which P(A \cap B) is the probability that the person does both thigs, so, in this problem, the probability that a randomly selected person aged 40 years or older is male and jogs.

So

P(A \cap B) = P(A).P(B/A) = 0.156*0.139 = 0.217

There is a 2.17% probability that a randomly selected person aged 40 years or older is male and jogs.

A probability is unusual when it is smaller than 5%.

So it would be unusual to randomly select a person aged 40 years or older who is male and jogs.
