If it reaches 250 bus stop shelters per month, then only the country can achieve their goal of 12000 bus stop shelters in 48 months.

Given,

The number of bus stop shelters a Country should built = 12,000

Time period for achieving the goal = 48 months

The average bus stop shelters the country can build in a month = more than 215

We have to explain that if they follow the above given format, will they achieve the goal in 48 months.

We can find it by using division operation;

Lets see;

Number of bus stop shelters they should build in one month = 12000/48 = 250

Here,

They are building more than 215 bus stop shelters per month.

If it reaches 250 bus stop shelters per month, then only the country can achieve their goal of 12000 bus stop shelters in 48 months.

1) The equivalent fraction is 27/8, so the correct option is A.

2) The value of the exponent in the right side must be y = 2, the correct option is C.

1) First we want to find an equivalent fraction to (2/3)^(-3)

Remember that a negative exponent means that we nee to take te inverse, we can write:

(2/3)^(-3) = (3/2)^3

Now we can just distribute the exponent along the numerator and denominator.

(3/2)^3 = (3^3)/(2^3) = 27/8

The correct option is A.

2) How to find the value of y?

Here we have the equation:

(3^3)^2/9^2 = 3^y

If we move the denominator to the right side, we can write:

(3^3)^2 = 9^2*3^y

Now, remember that:

9 = 3^2

Then we can write the right side as:

(9^2)*3^y = (3^2)^2*3^y = 3^(2*2)*3^y = 3^(4 + y)

Replacing that in the original equation we get:

(3^3)^2 = 3^(4 + y)

The exponent in the left side can be rewritten as:

(3^3)^2 = 3^(3*2) = 3^6

The the equation becomes:

3^6 = 3^(y + 4)

This is only true if:

6 = y + 4

6 - 4  =y

2 = y

The correct option is C.

If FC bisects ∠ACD and ∠ACD is a straight angles, then proved that the ∠ACF is a right angle

The ∠ACD is a straight angles

We know the angles on a straight line add up to 180 degree

Therefore,

The measure of angle ACD = 180 degrees

Here it is given that the line FC bisects angle ACD

Therefore, The angle ACF is equal to Angel DCF

Angle ACF = Angel DCF

Angle ACF + Angle DCF = 180 degrees

Then,

Angle ACF = Angel DCF  = 90 degrees

Hence, if FC bisects ∠ACD and ∠ACD is a straight angles, then proved that the ∠ACF is a right angle

What other external angles are there?

The alternate exterior angle theorem states that when two parallel lines cross, the exterior angles formed on either side of the transversal are equal. The distance between two intersecting lines or surfaces at or around their meeting point is referred to as the angle.

Since (2x - 30°) and (x+3)° are alternate exterior angles, they will be equivalent to one another.

(2x - 30)° = (x+3)°
Separate all similar phrases, then determine the value of x:
(2x - 30)° = (x+3)°
2x - x = 33 + 3
x = 33

Answer

500 tickets were sold

Step-by-step explanation:

Since 100 main floor tickets were sold, and each cost $7.50, we multiply it by 100 which equals $750, then since revenue was $3250, we do $3250 - $750 = $2500. Now that we got the extra tickets taken out of the way, time to find the rest. First, we add the prices of both tickets together, $7.50 + $5 = $12.50, then divide it by the remaining revenue, $2500 divided by $12.50 = 200 tickets, so 200 of each ticket were sold, + 100 main floor tickets. So now we do 300 main floor tickets + 200 balcony tickets, which is 500 tickets in total. Maybe you didn't read this but that's alright :)

Index (indices) in Maths is the power or exponent which is raised to a number or a variable. For example, in number [tex]2^{4}[/tex], 4 is the index of 2. The plural form of index is indices. In algebra, we come across constants and variables. The constant is a value which cannot be changed.

In the expression [tex]\frac{2^{3} . 2^{4} }{2^{12} }[/tex] all the indices have a common base 2

From numerator [tex]2^{3}[/tex] x [tex]2^{4}[/tex] = [tex]2^{3 + 4}[/tex]  which [tex]2^{7}[/tex]

so since the base at the numerator is same as that at the denominator we subtract their exponents

Step-by-step explanation:

A two sigma confidence interval is created whenever our alternate hypothesis does not equal a value.

For example if

[tex]h_{o} = 0.36[/tex]

and

[tex]h _{a} ≠0.36[/tex]

We used a two sigma confidence interval because we are thinking a portion is either below 0.36 or above 0.36.

When solving these probability for the p value, multiply the inital result by 2 to get the p value

The 2 sigma confidence interval is a principle that states that a result will be considered significant if 95% of the population is two standards deviation from the average value.

The two-sigma confidence level states that 95% of the values obtained in the results from a population should be within2 deviations from the mean. Anything below this acceptable percentage is not considered the 2-sigma confidence level.

If 68% of the score are within 1 standard deviation from the mean, then that will be considered the 1-sigma rule. If 99.7% of the score is 3 standard deviations from the mean then we can refer to that as the 3-sigma confidence interval.
