Answer:

×=40

Step-by-step explanation:

The total value of all the angles on any line is 180

so x+(4x-20)=180

40+(4×40-20)=180

Answer:

40°

Step-by-step explanation:

The sum of angles x and (4x - 20) is 180°

x + (4x - 20) = 180

5x = 200

x = 40°

A person rolls a standard six-sided die 9 times. In how many ways can he get 3 fours, 5 sixes, and 1 two?

marin [14]

Answer:

There are 5040 ways he get 3 fours, 5 sixes, and 1 two.

Step-by-step explanation:

Given : A person rolls a standard six-sided die 9 times.

To find : In how many ways can he get 3 fours, 5 sixes, and 1 two?

Solution :

A person rolls a standard six-sided die 9 times.

So, total number of ways die roll is 9! ways.

In die 4 comes 3 times.

So, ways of getting 4 is 3!

In die 6 comes 5 times.

So, ways of getting 6 is 5!

In die 2 comes 1 times.

So, ways of getting 2 is 1!

Total number of ways is given by,

$T=\frac{10!}{3!\times 5!\times 1!}$

$T=\frac{10\times 9\times 8\times 7\times 6\times 5!}{3\times 2\times 5!\times 1}$

$T=10\times 9\times 8\times 7\times$

$T=5040$

Therefore, there are 5040 ways he get 3 fours, 5 sixes, and 1 two.

Debbie has $460 in a savings account that earns 8% annually. If the interest is not compounded, how much interest will she earn

Viktor [21]

Compound interest means that the interest earned each year is added to the principal meaning that future interest is earned from the original amount + past interest.

In this case, it is NOT compounded meaning that we just have to find how much interested is earned in a year and multiply it by 5 years.

8% of $460 is 460*0.08 = 36.8

36.8*5 = 184

The answer is C) $184.00

NEED HELP ASAP!!!!! What is theoretical probability and experimental probability?

SVETLANKA909090 [29]

On the basis of mathematical theory, the chance of occurrence of any event is called theoretical probability.

For example if we toss a coin then the probability of a head and a tail is half half i.e 0.5.

But the probability calculated by repeated experiments and examine the outcomes are called experimental probability.

For example if we toss a coin 20 times and got 9 times head and 11 times head then the probabilities are given by

$P(\text{head})= \frac{9}{20} \\
\\
P(\text{head})= \frac{11}{20}$

These probabilities are different what we got in case of theoretical probabilities.
