Based on the price of the stamp in 1996, and the increase in 2010, the following are true:
a. price in 2010 = $7,875.b. amount of GST on the stamp in 2010 = $515.19c. percentage increase in GST from 1996 to 2010 = 405%.How much has the price of the stamp changed in 2010?The price in 2010 was:
= 3,500 x 225/100
= $7,875
The GST in 2010 is:
= (7,875 / 1.07) x 7%
= $515.19
The GST in 1996 is:
= (3,500 / 1.03) x 3%
= $101.94
The increase in the GMT is:
= (515.19 - 101.94) / 101.94

Rebecca bought 15 cupcakes for her birthday party, each cupcake was 3$ plus tax, the total bill was $47.25 how much tax did she pay on each cupcake
The tax paid by Rebecca on each cupcake was $0.15 or 15 cents, in the buying of 15 cupcakes for $47.25, where the cost of each was $3 plus taxes.
The tax is the amount paid to the government for buying and selling of goods are services.
In the question, we are informed that Rebecca bought 15 cupcakes, where each cupcake cost $3 plus taxes and the total bill to Rebecca was $47.25.
It implies that the cost of 15 cupcakes along with their taxes = $47.25.
Therefore, the cost of 1 cupcake along with its taxes = $47.25/15 = $3.15.
The cost of 1 cupcake is given as $3 plus taxes.
The total cost of 1 cupcake was $3.15.
Thus, the tax on 1 cupcake = $3.15 - $3 = $0.15 = 15 cents.
Thus, The tax paid by Rebecca on each cupcake was $0.15 or 15 cents, in the buying of 15 cupcakes for $47.25, where the cost of each was $3 plus taxes.

Answer:
AB = 14
Step-by-step explanation:
We can add the segments together to find the total
AB + BC = AC
This will allow us to find x
4x+2 + 3x-1 = 22
Combine like terms
7x +1 = 22
Subtract 1 from each side
7x+1-1 = 22-1
7x = 21
Divide by 7
7x/7 = 21/7
x = 3
Now we can find the length of AB
AB = 4x+2 = 4(3)+2 = 12+2 = 14

The probability that both sides of the card is red is 0.33
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

How do you solve this?
It looks like your equations are
7M - 2t = -30
5t - 12M = 115
Solving by substitution
Solve either equation for one variable. For example,
7M - 2t = -30 ⇒ t = (7M + 30)/2
Substitute this into the other equation and solve for M.
5 × (7M + 30)/2 - 12M = 115
5 (7M + 30) - 24M = 230
35M + 150 - 24M = 230
11M = 80
M = 80/11
Now solve for t.
t = (7 × (80/11) + 30)/2
t = (560/11 + 30)/2
t = (890/11)/2
t = 445/11
Solving by elimination
Multiply both equations by an appropriate factor to make the coefficients of one of the variables sum to zero. For example,
7M - 2t = -30 ⇒ -10t + 35M = -150 … (multiply by 5)
5t - 12M = 115 ⇒ 10t - 24M = 230 … (multiply by 2)
Now combining the equations eliminates the t terms, and
(-10t + 35M) + (10t - 24M) = -150 + 230
11M = 80
M = 80/11
It follows that
7 × (80/11) - 2t = -30
560/11 - 2t = -30
2t = 890/11
t = 445/11

Point X is the incenter of ΔABC.
Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X. Lines are drawn from point X to the sides of the triangle to form right angles. Line segments X F, X G, and X E are formed.
If EX = 4z + 1, XF = 2z + 7, and mABC = 44°, find the following measures.
GX =
mABX = °
The length of GX is 13 and the value of ∠ABX is 22.
We know that the point at which the triangle's three interior angle bisectors converge is known as the incenter. It can be thought of as the intersection of the triangle's internal angle bisectors. Due to the junction point of the central axis being the center of the triangle's inscribed circle, this point will be equally spaced from each of the triangle's sides. The center of a triangle's inscribed circle, which is the biggest circle that can fit inside the triangle, is known as the incenter.
Given that EX = 4z + 1 and XF = 2z + 7.
Since X is the incentre of this triangle ΔABC, EX = XF = GX.
Now, 4z + 1 = 2z + 7
i.e. 4z - 2z = 7 - 1
i.e. 2z = 6
i.e. z = 6/2 = 3
Then GX = 2 * 3 + 7 = 6 + 7 = 13
Also given that ∠ABC = 44°.
Since X is the incentre of this triangle ΔABC, ∠ABX = ∠CBX
Let ∠ABX = ∠CBX = y
Now y + y = 44
i.e. 2y = 44
i.e y = 44/2 = 22
Then ∠ABX = 22°
Therefore, the length of GX is 13 and the value of ∠ABX is 22°.

One year, there were about 3,000 institutions of higher learning in the U.S. (including junior colleges and community colleges). As part of a continuing study of higher education, the Carnegie Commission took a simple random sample of 400 of these institutions. The average enrollment in the 400 sample schools was 3,700, and the SD was 6,500. The Commission estimates the average enrollment at all 3,000 institutions to be around 3,700; they put a give-or-take number of 325 on this estimate. There were about 600,000 faculty members at institutions of higher learning in the U.S. As part of its study, the Carnegie Commission took a simple random sample of 2,500 of these faculty persons. On the average, these 2,500 sample persons had published 1.7 research papers in the two years prior to the survey, and the SD was 2.3 papers. If possible, find an approximate 95%-confidence interval for the average number of research papers published by all 600,000 faculty members in the two years prior to the survey. If this isn't possible, explain why not.
Thus an approximate 95% confidence interval for the average enrollment of all 60,000 faculty members in the two years prior to the survey. which implies that the given statement is true.

Average sample =3700
SD sample =6500

EV average+1⋅SE average =3700+1⋅325=3700+325=4025
EV average−1⋅SE average =3700−1⋅325=3700−325=3375

Which value of a in the exponential function below would cause the function to shrink? f(x) = a(three-halves) superscript x
The value of a in the exponential function is 4/5.
Given the exponential function is f(x)=a(3/2)ˣ.
An function may be a mathematical relation of the subsequent form: f(x)=aˣ. where x may be a variable, and a could be a constant called the exponential of the function.
When multiplying the any function by a constant, we may expand or shrink the function in the y-direction.
y=a(b)ˣ
If a>1 then the function will enlarge.
If a<1 then the function will shrink.
When a=4/5
Then 4/5<1 means the function would shrink.
When a=5/4
Then 5/4>1 means the function would enlarge.
When a=3/2
Then 3/2>1 means the function would enlarge.
When a=7/4
Then 7/4>1 means the function would enlarge.
Hence, the given function f(x)=a(3/2)ˣ would shrink when a=4/5.

The grocery store charges a retail price of $6.99 for a 24-pack of juice boxes. If it is wholesale, the prices are presented on the graph below. What is the difference between the retail and wholesale unit
price
The difference between the retail and wholesale unit price is $ 0.99.
What is retail price?The retail price is the price that the item is sold for to the customer.
Here,
Coordinates extracted from the graph;
(4, 1) (12, 3)
Equation of straight line (Whole sale price)
(y - y₁) = m(x - x₁)
where, m = (y₂-y₁)/(x₂-x₁)
then, m = (3-1) / (12-4)
= 2/8
= 1/4
Now, (y - 1) = 1/4 (x - 4)
4y - 4 = x - 4
x = 4y
x - 4y = 0
Now, whole sale price for 24 boxes; x = 24
24 - 4y = 0
4y = 24
y = 24/4
y = 6
The wholesale price = $ 6
The retail price = $ 6.99
The difference between retail and wholesale = Retail - Wholesale
= 6.99 - 6
= $ 0.99
Thus, the difference between the retail and wholesale unit price is $ 0.99.
