The mean of the given data is 22.6

In the given question, the following data reflects the overall enrollment in 10 universities of the open skies state in 2019:

23, 14, 27, 35, 7, 16, 25, 23, 35, 21.

We have to compute the mean.

As we know that;

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.

To find the mean we firstly add the given data then we divide the sum of data by the total number of data.

Mean = Sum of all data/ Total number

Mean = 23 + 14 + 27 + 35 + 7 + 16 + 25 + 23 + 35 + 21/10

Mean = 226/10

Mean = 22.6

The statement that describes why this sequence is a function is given as follows:

A.The graph of the sequence would pass the vertical line test.

A relation represents a function when each value of the input is mapped to a single value of the output.

In this problem, the input is the number of days, while the output is the number of cans. There are no repeated inputs, which means that this relation is a function.

On the graph, a relation being a function means that a vertical line will intercept the graph of the function only once, and thus option A is correct.

Answer:

f1= -2+1/3

f2= 0

Step-by-step explanation:

3f^2+7f=0

a = 3; b = 7; c = 0;

Δ = b2-4ac

Δ = 72-4·3·0

Δ = 49

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

f1=−b−Δ√2af2=−b+Δ√2a

Δ−−√=49−−√=7

f1=−b−Δ√2a=−(7)−72∗3=−146=−2+1/3

The linear equation that is parallel to 8x - 10y = -2 and contains (1, -2) is:

4x - 5y = 14

So the last option is the correct one.

Remember that two linear equations are parallel only if both lines have the same slope (or coefficients if it is written in standard form) and different y-intercept.

Here our line is:

8x - 10y = -2

If we divide all the equation by 2, we will get:

(8x - 10y)/2 = -2/2

4x - 5y = -1

So any equation of the form:

4x - 5y = c, where c ≠ -1

Is parallel to 8x - 10y = -2

Now we want our line to pass through (1, -2), replacing these values in our line we get:

4x - 5y = c

4*1 -  5*-2 = c

4 + 10 = c

14 = c

Then the linear equation is:

4x - 5y = 14

So the correct option is the last one.

In 5th year, Anisa and Keith have the same amount of stock value. Anisa bought $100 worth of stock and gained $25 per year. Kevin bought $400 worth of stock and lost $35 per year.

In mathematics, an equation is a relationship between two expressions that is expressed as an equality on each side of the equal to sign. An equation would be 3y = 16, for instance.

Given

1. For Anisa

For our problem, we know that she will make $25 annually, thus if x denotes the number of years in which she will make this gain 25x. She made a $100 initial deposit, which is also known as y. The following equation can be used to link the quantities if we assume that the stock value will remain constant throughout time:

y = 25x + 100

2. For Kevin

He is currently losing $35 annually. Let the x years be represented. He will lose -35 times year because we know that losses are represented by a minus sign. We now know that her initial investment y in our situation was $400. The following equation can be used to link the quantities if we assume that the stock value will remain constant throughout time:

y = -35x + 400

On year 5th

For Anisa

y = 25(5) + 100

y = 125 + 100

y = 225

For Kevin

y = -35x + 400

y = -35(5) + 400

y = -175 + 400

y = 225

In 5th year, Anisa and Keith have the same amount of stock value.

Rounding to the nearest whole number, the limits for a 'b' grade are 75 and 81

In this question we have been given a philosophy professor assigns letter grades on a test according to the given scheme.

We need to find the numerical limits for a b grade.

b: scores below the top 12 % and above the bottom 63 % which means scores between the  63th and 88th percentile.

Given that the scores on the test are normally distributed with a mean of 72 and a standard deviation of 8.1

μ = 72, σ = 8.1

z-score at the 63th percentile: 0.332

z-score at the 88th percentile: 1.175

The lower limit of a 'b' grade is:

0.332 = X - μ/σ

0.332 = (X - 72)/8.1

2.67 = X - 72

X = 74.67

X ≈ 75

The upper limit of a 'b' grade is:

1.175 = X - μ/σ

1.175 = (X - 72)/8.1

9.52 = X - 72

X = 81.52

X ≈ 81

Therefore, you get a 'b' if you have a grade between 75 and 81

Data distribution in reference to the mean is measured by a standard deviation, or. Samples are said to be more narrowly collected around the mean when the standard deviation is minimal and more dispersed when the standard deviation is higher.

While a high or low standard deviation implies that data points are, respectively, above or below the mean, a standard deviation that is close to zero suggests that data points are, on the other hand, relatively close to the mean.

Answer: $5

Step-by-step explanation: To calculate how much she spent on the 4 boxes of candy, we need to subtract 5 from 25, because we won't be including the cost of the magazine. So, therefore 25-5 is 20. So, now to find the cost for one, we need to set up a proportional relationship like this:

[tex]\frac{20}{4}[/tex] = [tex]\frac{?}{1}[/tex]

So, with that, we need to divide 4 by 20 to find the cost of 1. So, if you know, 20 divided by 4 = 5. So, therefore the cost of each candy box is $5. We can check our answer if we use the inverse operations, so our new equation would look like this:

5(4) + 5 = 25

We can check this, because we know 5 x 4 = 20, and 20 + 5 = 25. So 25 = 25, so it is $5.00

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

An item is connected to a spring that is extended and delivered. The condition d= - 8cos [(π/6) t] the distance, d, of the item creeps above or underneath the rest position as an element of time, t, in a flash.

d= - 8cos [(π/6) t]

If d = 6, then the value of the variable 't' is calculated as,

6 = - 8cos [(π/6) t]

- 3/4 = cos [(π/6) t]

cos [(77/100)π] = cos [(π/6) t]

As x approaches positive infinity, the function r(x) approaches negative infinity.

What is a function approaches infinity?

In general, a fractional function will have an infinite limit if the limit of the denominator is zero and the limit of the numerator is not zero.

As x approaches positive infinity, the term x^3 becomes dominant, and the value of the function p(x) approaches positive infinity as well.

In general, when the highest-order term in a polynomial function has a positive coefficient, the function will approach positive infinity as x approaches positive infinity.

Similarly, if the highest-order term has a negative coefficient, the function will approach negative infinity as x approaches positive infinity.

For example, consider the function q(x) = 3x^3 - 2x^2 + x - 5. As x approaches positive infinity, the term 3x^3 becomes dominant, and the function q(x) approaches positive infinity. On the other hand, if we consider the function r(x) = -3x^3 + 2x^2 - x + 5, the highest-order term is -3x^3, which has a negative coefficient.

Therefore, as x approaches positive infinity, the function r(x) approaches negative infinity.

Humans are drawn to foods that are fatty, sweet, rich and complex. Pizza has all of these components.

Notice that I expressed cost in terms of cents so

that we can avoid having to deal with decimals.

In our second equation, 4 slices of pizza and

10 sodas cost $37, that's 4p + 10s = 3700.

Now let's rewrite our two equations on top of one another.

8p + 5s = 3650

4p + 10s = 3700

To solve this system of equations, I would use addition.

I would multiply the bottom equation by -2

to create a situation where our p's will cancel.

When we do that, we get -8p - 20s = -7400.

Now rewrite the equations once again ~

8p + 5s = 3650

-8p - 20s = -7400

Now add the equations together.

So we have -15s = -3,750.

Divide both sides by -15 and s = 250.

Remember that I expressed cost in terms of cents so

since s = 250, it really means that a soda is $2.50.

Now just plug an s back in for the s in one equation.

When we do this, we find that p = 300.

So a pizza is $3.00
