Find the value of x in the triangle shown below
tino4ka555 [31]

Answer:

<em>x = 32</em>

Step-by-step explanation:

This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.

x + x + 116 = 180

2x + 116 = 180

2x = 64

x = 32

How do I solve this problem?
yulyashka [42]

Answer:

$10,000

Step-by-step explanation:

You can define a variable that represents the answer to the question: the amount invested at 3.5%. Let's say that is x. Then the amount invested at 5% is 16000-x, and the total interest earned is ...

0.035·x + 0.05·(16000 -x) = 650

-0.015x +800 = 650 . . . . . . . . . . . . simplify

-0.015x = -150 . . . . . . . . . . . . . . . . . subtract 800

x = 10,000 . . . . . . . . . . . . . . . . . . . . divide by -0.015

The amount that should be invested at 3.5% is $10,000.

A skilled chess player believes that when they play a novice opponent, there is a 90% probability they will be able to beat them
zavuch27 [327]

Answer:

b) Binomial

c) Poisson

Step-by-step explanation:

The geometric distribution is the number of trials required to have r successes. The measures the number of sucesses(wins), not the number of trials required to win r games. So the geometric distribution does not apply.

For each match, there are only two possible outcomes, either the skilled player wins, or he does not. The probability of the skilled player winning a game is independent of other games. So the binomial distribution applies.

We can also find the expected number of wins of the skilled player, which is 15*0.9 = 13.5. The Poisson distribution is a discrete distribution in which the only parameter is the expected number of sucesses. So the Poisson distribution applies.

So the correct answer is:

b) Binomial

c) Poisson
