Kara compared the number of text messages 100 students sent in one day and the grade point average (GPA) of each student. The correlation coefficient among the
data is -0.9 rounded to the nearest tenth. Based on this information, which statement is MOST likely true?
OA. There is correlation but not causation between GPA and the number of text messages.
B. There is causation but not correlation between GPA and the number of text messages.
OC There is both correlation and causation between GPA and the number of text messages.
D. There is neither correlation nor causation between GPA and the number of text messages.

Answers

Answer 1

There is correlation but not causation between GPA and the number of text messages. that is option A is correct.

The correlation coefficient is defined.

How one variable changes in relation to another is indicated by the correlation coefficient. A score of 1 shows a complete positive correlation, with a positive correlation being one where both variables move in the same direction. While 0 indicates there is no linear connection, a number of -1 indicates a complete negative correlation.

Given to us is that The data have a -0.9 correlation coefficient.

That is, there is a significant inverse relationship between the quantity of texts and each student's grade point average (GPA).

Hence, choice A is right.

There is correlation but not causation between GPA and the number of text messages.

option B,C,D are incorrect because we know that correlation does not imply causation that is correlation does not imply  a cause and effect between the two variable. correlation between variables means that relationship between two variables not the change in one variable , is the cause of the change in the variable. causation indicates that one event is the result of the occurrence of the other event.

Sebastian has x nickels and y pennies. He has at least 20 coins worth at most $0.65 combined.

Answers

If Sebastian has x nickels and y pennies. He has at least 20 coins worth at most $0.65 combined then he has 27 nickels.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

x represents nickels and y represents dimes.

x+y=20...(1)

0.05x+0.10y=0.65...(2)

From equation 1,

y=20-x

0.05x+0.10y=0.65

0.05x+0.10(20-x)=0.65

0.05x+2-0.10x=0.65

2-0.05x=0.65

Subtract 2 from both sides

-0.05x=0.65-2

-0.05x=-1.35

Divide both sides by -0.05

x=27

x+y=20

27+y=20

y=20-27

y=-7

Hence the number of nickels are 27 and dimes are minus seven.

Answers

Using percentages we know that the next score Michelle is hoping to obtain is 1,350.

What is the percentage?

In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.

Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.

A% is a number that has neither dimensions nor a defined unit of measurement.

So, we know that:

Michelle received a score of 1080.

Her exam will be retaken in a few months.

She wants to increase her grades by 25%.

Scores Michelle is hoping for:

(1080/100 * 25) + 1080

270 + 1080

1,350


Therefore, using percentages we know that the next score Michelle is hoping to obtain is 1,350.

United Parcel Service has contracted you to design an open box with a square base that has a volume of 5000 cubic inches. Express the surface area S of the box as a function of x.

Answers

The surface area of the box as a function of x will be f(x) = x² + 20000/x² where x is the length of the square base's edge.

Here it is given that the box has a square base.

This implies that length = breadth

Now, the volume of a box = lbh = 5000 cu in

where l is the length of the box. b is the breadth of the box, and h is the height of the box.

or, x²h = 5000

or, h = 5000/x²

Let the surface area function be f(x) where x is the length of the edge of the square base.

Since the box is open, the surface area will be

lb + 2bh + 2lh

= x² + 10000/x² + 10000/x

= x² + 20000/x²

Hence the surface area as a function of x will be

Answers

The given statement that 'the batter's distance from the first base bag is a function of time.' is false.

If we need to call any quantity a function of any other quantity, we need to know what it means first. For this, we take the example of velocity. If we say that velocity is a function of time, what we mean is that the function is such that we input time and get velocity as the output. That quantity changes as the input increases or decreases.

We can deem distance as a function of time when it changes with respect to it. Here, it is evident that the distance between the batter and the first base is not going to change. Thus, it is not a function of time and the given statement is false.

How do you factor polynomials with 4 terms without grouping?

Answers

We can factor this polynomial with 4 terms without grouping.

What is factor?

Factor is a thing that influence decision or the situation.

How to factor polynomials with 4 term without groupingLet P(x) be a polynomial with four terms.

To factor P(x) without grouping, substitute

x = -1, 1, -2, 2, -3, 3.......

P(-1) = 0 ----> (x + 1) is a factor of P(x)

P(1) = 0 ----> (x - 1) is a factor of P(x)

P(-2) = 0 ----> (x + 2) is a factor of P(x)

P(2) = 0 ----> (x - 2) is a factor of P(x)

If P(-1) ≠ 0, then (x + 1) is not a factor of P(x).

Then, try x = 1, x = -2, x = 2 and so on.

Once one of the linear factors of P(x) is found, the other factors can bound easily (the rest of the process has been explained in the following examples).

Factor the following polynomials without grouping :

d as (x2 + ax + b).

Then,

(x + 1)((x2 + ax + b) = x3 - 2x2 - x + 2

Comparing the coefficients of x and constants,

b + a = -1 ----(1)

b = 2

Substitute b = 2 in (1).

2 + a = -1

a = -3

x2 + ax + b = x2 - 3x + 2

Factors of (x2 - 3x + 2) are (x - 1) and (x - 2).

Therefore,

x3 - 2x2 - x + 2 = (x + 1)(x - 1)(x - 2)

For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.

So, we have the equation:

x⁴ + 95x² – 500 = 0

Factorizing the above equation:

x⁴ + 100x² - 5x² - 500 = 0

x²(x² + 100) - 5(x² + 100) = 0

(x² - 5)(x² + 100) = 0

Solving further:

x² = 5

x² = -100

x = ±√5

x = √-100

Factors: ±√5 and ±10i

Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.
