The value of g, for a 30-sided regular polygon has an angle measure represented as 6g° is calculated to be 28
How to find the value of gThe problem is solved using the formula for number of angles for n sided polygon
The formula is (n - 2)180
where n = number of sides
for 30-sided polygon the angles is solved as below
= (n - 2)180
= ( 30 - 2 ) * 180
= 28 * 180
= 5040
this is represented as 6g
each angle is measured 5040 / 30 = 168
6g = 168
g = 28

Now we will calculate the actual probability that all a randomly chosen student has a schedule that excludes music theory. We have found that the probability is given as P=4C38C3 Express your answer as a fraction in simplest form.
The probability that all a randomly chosen student has a schedule that excludes music theory, using the combination formula, is of:
p = 1/14.
What is the combination formula?The number of different combinations of x objects from a set of n elements is obtained with the formula presented as follows, using factorials.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Without simplifying it, the probability that all a randomly chosen student has a schedule that excludes music theory is of:
[tex]p = \frac{C_{4,3}}{C_{8,3}}[/tex]
The numeric value for each of these combinations is given as follows:
[tex]C_{4,3} = \frac{4!}{3!1!} = 4[/tex][tex]C_{8,3} = \frac{8!}{3!5!} = 56[/tex]Hence the probability is given as follows:
p = 4/56.
The division of 56 by 4 has a quotient of 14, hence the simplified probability is of:
p = 1/14.

The Magazine Mass Marketing Company has received 16 entries in its latest sweepstakes. They know that the probability of receiving a magazine subscription order with an entry form is 0.4. What is the probability that no more than 3 of the entry forms will include an order? Round your answer to four decimal places.
Answer: The probability that more than 12 of the entry forms will include an order is 0.624.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The Magazine Mass Marketing Company has received 16 entries in its latest sweepstakes.
The probability that more than 12 of the entry forms will include an order can be found as:
P(X > 4) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P( X = 3) - P(X = 4)
P(X > 4) = 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3) - P(X = 4)
P(X > 4) = 1 - 0.0009 - 0.0097 - 0.043 - 0.117 - 0.205
P(X > 4) = 0.624
Thus, the probability that more than 12 of the entry forms will include order is 0.624.

A apple and a blueberry muffin now cost as much as a cherry muffin. A cherry muffin and two damson ones now cost the same as two apple and one blueberry. How much would Aanya now spend to buy one of each?
Aanya will now buy each at the cost below
A cherry muffin costs 350 shillings
A blueberry muffin costs 210 shillings
An apple costs 140 shillings
damson ones costs 70 shillings
How to determine the cost of eachThe information given in the question is interpreted as below
A cherry muffin = 350 shillings
A blueberry muffin = 3 * damson ones
An apple + a blueberry muffin = 1 cherry muffin
A cherry muffin + 2 damson ones = 2 apple + 1 blueberry
from: 1 blueberry muffin, B = 3 * damson ones, D
D = B / 3
Also, An apple, A + B = 1 cherry muffin, C
A = C - B
C + 2D = 2A + B
substituting the values
350 + 2 * (B/3) = 2 * (350 - B) + B
350 + 2B/3 = 700 - 2B + B
collecting like terms
2B/3 + B = 700 - 350
5B/3 = 350
5B = 1050
B = 1050/5
B = 210
Solving for cost of apple
A = C - B = 350 - 210 = 140

Because of market demand the farmer will grow twice as many acres of wheat as of corn. He has allocated $67,050 for the cost of growing his crops. How many acres of each crop should he plant?
If he has allocated $67,050 for the cost of growing his crops. The number of acres of each crop that should plant is Corn 270, Wheat 540, Soybeans 450.
How to determine the number of acres?Let c = corn
Let w = wheat
Let s = soybeans
C+W+S = 1260
45C + 60W + 50S = 67050
W =2C
Substitute equation 1 into equation 2
C + 2C +S = 1260
3C + S =1260
45C + 120C + 50S =67050
165C +50S =67050
Let eliminate S
165C+ 50(1260-3C) =67050
165C + 63000 - 150C= 67050
15C= 4050
Divide both side by 15c
c =4050/15
c = 270 (corn)

W=2C
w = 2(270)
w= 540
S= 1260 - 3C
S= 1260- 3(270)

To add fractions, they must have a common denominator. To set one, find a common multiple of both denominators. Simply multiply them together if it proves difficult.
7 x 39 = 253
Now set the denominators to this number and multiply the numerators by the opposite fraction's denominator.
39/259 + 7/253 = 46/253
