Percentage of the cupcakes that had sprinkles = 30 %

Percentage

Percentage, often referred to as percent, is a fraction of 100. Percentage means "per 100," and denotes part a total amount. For example, 45% represents 45 out of 100.

Proportion

The proportion formula is used to depict if two ratios or fractions are equal. We can find the missing value by dividing the given values. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The first step is to divide 12 by 40 to get the answer in decimal form:

12 / 40 = 0.3000

Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.3000 * 100 = 30.00%

Percentage of the cupcakes that had sprinkles = 30 %

The linear function to model the amount of money in her checking account at any time t is 185 + 5.55t.

An interest simply means the extra amount that's borrowed when one borrows money or when one saves.

In this case, the checking account pays simple interest at 3% per year. She has $185 in her account.

The amount of money in the account at anytime will be:

= 185 + (PRT/100)

P = principal

R = rate

T = time

= 185 + [(185 × 3 × t)/100]

= 185 + 5.55t

we  know [tex]i^{2}[/tex] = -1

((-1²))⁵  [tex](i^{2} .i)[/tex]

we know that -1² = 1

Answer: 4374

If Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras

The distance traveled by Mr. Giordano = 4.5 miles

The time taken = 5 minutes

Speed = Distance / Time

Substitute the values in the equation

Speed = 4.5/5

= 0.9 miles per minutes

The distance traveled by Mr. Baras = 6.3 miles

The time taken = 8 minutes
Speed = Distance / Time

Substitute the values in the equation

Speed = 6.3/8

= 0.78 miles per minutes

Hence, if Mr. Giordano's drove 4.5 miles in 5 minutes and Mr. Baras drove 6.3 miles in 8 minutes, then the Mr. Giordano drove fast because speed of Mr. Giordano is greater than Mr. Baras

The area in square inches of the tile is 9 / 4 t .

She makes rectangular kitchen tiles with an area of t square inches.

Therefore,

area of the rectangular kitchen tiles = lw

t = lw

l = t / w

w = t / l

Therefore, the tile is 3 / 4 as long and 3 times wide as her kitchen tiles.

Hence,

area of the tile = 3 / 4 t / w × 3(t / l)

area of the tile = 9 / 4 × t² / lw

where

lw = t

Hence,

area of the tile  = 9 / 4 × t² / t

area of the tile  = 9 / 4 × t

P(A). P(Y)= 0.5*0.6=0.3

Probability: - Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

Number of cases of A, N(A)= 250,

So,

     P(A)=250/500 =0.5

and

      N(Y)= 300, so P(Y)=300/500 =0.6

N(A and Y)= 175 so P(A and Y)= 175/500=0.35

A and Y are mutually exclusive implies A and Y donot have any elements in common, but here there are 175 people who are below 30 years and under the influence of alcohol, So they are not mutually exclusive!!

For A and Y to be independent, the Probability of A intersection Y should be equal to the product of their respective probabilities,

in this case P(A). P(Y)= 0.5*0.6=0.3 which is not equal to P( A intersection Y) (0.35)

What do you mean by linear equations with one variable?

A linear equation with one variable is one that can be written as ax+b = 0, where a and b are two integers, and x is a variable. This type of problem only has one solution. For instance, the linear equation 4x+4=8 only has one variable.

We are given that,

the total money raised by the lacrosse team is given to be $2863.50

bus rented at a cost of $1087.50

meal budget per person is calculated to be $74

let us assume the number of players the team can bring to the tournament to be "x".

bus rent + (meal budget * number of players) = total money raised

= 1087.50 + (74*x) = 2863.50

= 1087.50 + 74x = 2863.50

= 74x = 2863.50 - 1087.50

= 74x = 1776

= x = 1776 ÷ 74

= x = 24

Thus the team can bring its 24 players.

The probability of making no sales in 100 tries is 0.97^100. That's equal to about 0.0476, so the probability of getting at least one sale is 0.9524. About 95%.

If the probability of making a sale is 0.03 then the probability of not making a sale must be 1-0.03 which is 0.97.

So looking at contacting 100 prospects, you could say there are two general outcomes. Either the salesman makes no sales at all, or he makes at least one sale. There are no other possible outcomes, so the probability of those two outcomes must add up to 1.

So the probability of making of at least one sale is 1 minus the probability of making no sales.

The probability of making no sales in 100 tries is 0.97^100. That's equal to about 0.0476, so the probability of getting at least one sale is 0.9524. About 95%.

The value of b for which the difference between the fractions

 (2b - 1) / 2 and  (1 + 5b) / 4 negative will be;

⇒ b < -3

What is Fraction?

A fraction is a part of whole number, and a way to split up a number into equal parts.

Given that;

Two fractions are,

⇒ (2b - 1) / 2 and  (1 + 5b) / 4

Since, The difference between the fractions  (2b - 1) / 2 and  (1 + 5b) / 4 negative.

So, we can formulate;

⇒ (1 + 5b) / 4 - (2b - 1) / 2 < 0

Solve for b, as;

⇒ 1 + 5b - 2 (2b - 1) < 0 x 4

⇒ 1 + 5b - 4b + 2 < 0

⇒ b + 3 < 0

Subtract 3 both side;

⇒ b + 3 - 3 < 0 - 3

⇒ b < -3

Therefore, The value of b for which the difference between the fractions  (2b - 1) / 2 and  (1 + 5b) / 4 negative will be;

Slope of the line graph here is undefined.

When a line is vertical, its slope is ambiguous. A vertical line lacks the horizontal distance required for a positive, negative, or zero slop to exist. Since there is no horizontal change, there is no slope for vertical lines because 0 cannot be divided into any integer.

It is obvious that the x-coordinates are the same if we have a pair of coordinates, (x1, y1) and (x1, y2) through which a line passes. They are the same vertical line's points. As a result, the slope of such a line will be ambiguous.

Examples of undefined slope in real-world situations include elevators that only go up and down, and a mountain cliff that is vertical for a certain amount of height but impossible for climbers to scale.

Step-by-step explanation:

Answer:

Maximum area enclosed will be 101250 meter².

Step-by-step explanation:

Let the length of the rectangular plot is x meters and the width is y meters.

900 meters is the length of the fence which represents the length of the three sides of the plot.

Therefore,

x + 2y = 900

y =  meters

Now the area of the rectangular plot will be

A = Length × Width

  = (x)(y)

  = 

  = 450x - 

We know for the maximum area we will differentiate the area and equalize it t the zero.



= 450 - x

For the maximum area, 

Therefore, 450 - x = 0

x = 450

and y = 

y = 

y = 450 - 225

Jonas have to repay $13888 after 4 years.

Given

Principle amount of loan (P) = $12,400

Rate of interest (R) = 3%

Time period (T) = 4 years

Also the interest is not compounded, hence it is simple interest.

The formula for simple interest is (PTR)/100

Where,

P = Principle amount

T = time period

R = rate of interest

By substituting the values in the formula we get,

Simple interest =  (12400 x 4 x 3) / 100

Simple interest = 1488

Hence adding this interest to Principle sum we get

12400 + 1488 = 13888
