2. What Is The Value Of X?

Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

The total degrees in a 4 sided polygon is 360°

360° = 51° + 51° + 2(28x - 11°)

56x - 22° + 51° + 51° = 360°

56x = 280°

x = 5

What is the probability that a randomly selected student
is a junior who takes the bus?
?
P(Junior' n Take the bus)

Answers

Answer:

The answer is 1/5

Step-by-step explanation:

Trust me.

The probability that a randomly selected student is a junior who takes the bus is  [tex]\frac{1}{5}[/tex] .

What is probability?

Probability or chance is how likely something is to happen. If something has a low probability, it is unlikely to happen. If something has a high probability, it is likely to happen.

[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]

Given,

Total number of students = 100

Number of students who are juniors and take bus = 20

[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]

Probability of junior students who take bus =  [tex]\frac{20}{100}[/tex]

Probability of junior students who take bus =  [tex]\frac{1}{5}[/tex]

Hence, The probability that a randomly selected student is a junior who takes the bus is  [tex]\frac{1}{5}[/tex] .

Write an expression to describe the sequence below. Use n to represent the position of a term in the sequence, where n = 1 for the first term.

10, 11, 12, 13

Answers

Answer:

[tex]9 + n[/tex]

Step-by-step explanation:

Well it's an arythmetic sequence, so it will look like:

[tex]a + d\cdot n[/tex]

Note that the first element is:

[tex]a + d\cdot 1[/tex]

and the second element is:

[tex]a + d \cdot 2[/tex]

So the difference between the two gives us d!

[tex]d = 11 - 10 = 1[/tex]

Now let's find the [tex]a[/tex]:

[tex]a + d\cdot 1 = 10\\a + 1 \cdot 1 = 10\\a + 1 = 10\\a = 9[/tex]

In order to prove triangle similarity by AAA what does X have to equal?

Answers

Answer:

x has to be equal to 12

Step-by-step explanation:

In other to prove that the triangles are similar, the values of the angles at certain points must be equal

for example, the angle at the top vertices should be equal

So, we have it that;

6x = 3x + 36

6x-3x = 36

3x = 36

x = 36/3

A TV has a listed price of $616.99 before tax. If the sales tax rate is 9.75%, find the total cost of the TV with sales tax included. Round your answer to the nearest cent, as necessary.

Answers

Answer:

The sales tax is determined by computing a percent of the purchase price. To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price.

A meteorologist in Seattle says there is a 75% chance of rain. A meteorologist in Tacoma says there is a 1/4 chance of rain. In which city is it more likely to rain?

A. Seattle
B. Tacoma
C. Batesville
D. Both have the same chance

Answers

Answer: A. Seattle

Steps:
1/4 = 25%

Which is more 25% or 75%?
The answer is 75%
Assuming both predictions are correct, converting the number forms into the same form, we can see that it is equally likely to rain in either city.
Explanation:
Firstly, we're going to assume that both predictions are correct, because, well, they're just predictions. Let's write them down:
Seattle Rain Chance
=
75
%

Tacoma Rain Chance
=
3
4

Now, we can see that both predictions are in different forms: one in the form of percentage, and the other in the form of a fraction. To compare, we could convert one of them... Let's convert the fraction into a percentage. But, how?
Well, what "percent" means is "per hundred". We could multiply the number by
1
, which shouldn't change anything...
... but then convert it to
100
100
(because they both divide out into
1
)...
... and finally, by definition, to
100
%
:
1
=
100
100
=
100
%

Tacoma Rain Chance
=
Tacoma Rain Chance

1
Tacoma Rain Chance

1
=
Tacoma Rain Chance

100
%
Let's evaluate it:
Tacoma Rain Chance
=
3
4

100
%
=
300
4
%
=
75
%
Now let's compare it to the Seattle rain chance:
Seattle Rain Chance
=
75
%

Whew, they're equal!
Seattle Rain Chance
=
Tacoma Rain Chance
Therefore, with the assumption that both predictions are correct, it is equally likely to rain in either city.

Suppose you had to decide between an apartment that cost $800/month for a month-to-month contract, or $650 for an annual contract. The annual contract includes a 2- month early termination penalty if you leave before 12 months

Answers

Answer:

Step-by-step explanation:

Incomplete question, but if my guess is correct, you're trying to determine which is a better deal between the two. I will go with the second one. The $650/month rent.

I choose so because, $800/month totals to $9600 at the end of the year. While $650/month totals to $7800 per year. Again, with the $650/month, if you try to leave before the end of the year, say 11 months even, you pay a penalty of $1300, which still leaves you on the profit side. And the whole idea of choosing is to find which is more beneficial and cost effective.

Number 6 would be (a) 88 degrees

Number 7 would be (c) 45 degrees

Step-by-step explanation:

What is this Geometry? I haven't done this in so long so i went to look it up online and was shocked because of how much i was overthinking it.

For number 6, since we already have the angle listed as 44 degrees, to find the arc degrees, we would multiply the 44 by two. The formula is basically mAB=2(m<C)=88.

For number 7, we already have the arc degrees, so we would have to divide by two in this case to find the angle. The formula for this would be m<X=1/2(mYZ)=45.
