Answer:

75 degrees

Step-by-step explanation:

1. Find angle J.

The outside angle and angle J are supplementary, which means they add up to 180 degrees.

180 - 130 = 50.

So angle J is 50 degrees.

2. The angles in a triangle add up to 180. Add up angles J and K and subtract that from 180

50 +65 = 105

180- 105 = 75

IF PROBABILITY RANDOMLY CHOSEN ATHLETE IS A SWIMMER IS 0.65, THEN WHAT IS THE PROBABILITY CHOSEN ATHLETE IS NOT A SWIMMER? GIVE

Vsevolod [243]

Answer:

0.35

Step-by-step explanation:

a randomly chosen person's chance of being an athlete is 100%, or 1.00

Therefore: if the probability of a randomly chosen athlete is a swimmer is 0.65 or 65%, The probability of a randomly chosen athlete to NOT be a swimmer is:

1.00 - 0.65 = 0.35 or 35%

If paul puts 300 dollars in a saving account that earns 3% interest how much interest will he earn after 2 years?

Evgesh-ka [11]

Answer:

<h2> $\boxed{18 \: dollars}$ </h2>

Step-by-step explanation:

Principal ( P ) = $ 300

Rate ( R ) = 3%

Time ( T ) = 2 years

Now, let's find the simple Interest:

I = $\mathsf {\frac{PTR}{100} }$

$\mathsf{ = \frac{300 \times 2 \times 3}{100} }$

$\mathsf{ = \frac{1800}{100} }$

$\mathsf{ = 18}$

Extra information:

Simple Interest

In our daily life when we borrow a sum of money either from a moneylender or from any financial company, we have to pay the money back by adding with extra sum of money. This borrowed money is called principal. The extra money to be paid for the borrowing money is called interest , which is paid after certain duration in certain rate. At last, the borrowed money should be paid back along with interest which is called amount.

Interest is based on three factors : Principal ( P ) , Rate of interest ( R ) and Time ( T ). While computing the interest, the rate must be in percent and time in years.

$\mathsf{ \: simple \: interest \: = \frac{PTR}{100} }$
