Explain your reasoning.

Answers

Answer:

A function defines one variable in terms of another. The statement "y is a function of x" (denoted y = y(x)) means that y varies according to whatever value x takes on. A causal relationship is often implied (i.e. "x causes y"), but does not *necessarily* exist.

Timed test

Answers

Answer:

profit = revenue - cost

10 = 20x - (4.5 + 2.5)

10 = 20x - 7

10 + 7 = 20x

17 = 20x

17/20 = x

0.85 = x

check...

profit = revenue - cost

10 = 20(0.85) - 7

10 = 17 - 7

10 = 10 (correct)

so he would have to sell each cup at 0.85 ccents to make a profit of $ 10

168 Inches. One is three times the length of the other so, the bigger piece is 3/4 while the shorter is 1/4. Simply multiply 1/4 by 168. You get 42.

point Q was rotated about the origin (0,0) by 180

Answers

Answer:B

Step-by-step explanation:

The coordinates of the image of the rotation of the point Q is:

Q' = (4, 2)

What is the image of the rotation?

We can see that the original coordinates of point Q are (-4, 0).

If we apply a rotation of 180° about the point (0, 0), it is equivalent to a reflection around the y-axis.

It only changes the sign of the x-component.

Then the image of the rotation is:

Q' = (4, 0)

Consider the following probability distribution function of the random variable X which represents the number of people in a group (party) at a restaurant: X P(X) 1 0.10 2 0.25 3 0.20 4 0.20 5 0.10 6 7 0.05 8 0.05 a. Find the population mean of X. b. Find the population variance and standard deviation of X. c. Find the probability that the next party will be over 4 people. d. Find the probability that the next three parties (assuming independence) will each be over 4 people.

Answers

Answer:

(a) 3.55

(b) 3.45 and 1.86

(c) 0.25

(d) 0.016

Step-by-step explanation:

The random variable X denotes the number of people in a group (party) at a restaurant.

(a)

The formula to compute the mean is:

[tex]\mu=\sum {x\cdot P(X=x)}[/tex]

Consider the Excel sheet attached.

The mean is, 3.55.

(b)

The formula to compute the variance is:

[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}[/tex]

Consider the Excel sheet attached.

Compute the variance as follows:

[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}\\\\=16.05-(3.55)^{2}\\\\=3.4475\\\\\approx 3.45[/tex]

The variance is, 3.45.

Compute the standard deviation as follows:

[tex]\sigma=\sqrt{\sigma^{2}}\\\\=\sqrt{3.45}\\\\=1.85742\\\\\approx 1.86[/tex]

The standard deviation is, 1.86.

(c)

Compute the probability that the next party will be over 4 people as follows:

[tex]P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\=0.10+0.05+0.05+0.05\\\\=0.25[/tex]

Thus, the probability that the next party will be over 4 people is 0.25.

(d)

Compute the probability that the next three parties will each be over 4 people as follows:

It is provided that the three parties are independent.

P (Next 3 parties will be each over 4) = [P (X > 4)]³

                                                           [tex]=(0.25)^{3}\\=0.015625\\\approx 0.016[/tex]

Thus, the probability that the next three parties will each be over 4 people is 0.016.

Step-by-step explanation:

Tia bought less expensive printer.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Vanessa and Tia buy a printer. Vanessa pays $90 for her printer and each replacement ink cartage cost $25. The equation T = 80 + 20c can be used to find the total cost, T, Tia pays for her printer plus C number of ink cartridges.

Equation that represents the cost for Vanessa's printer is -

V = 90 + 25c

Equation that represents the cost Tia's printer is -

T = 80 + 20c

For {c} = 1, the cost for Vanessa's printer is -

V(1) = $115

For {c} = 1, the cost for Tia's printer is -

T(1) = 80 + 20 = $100

Therefore, Tia bought less expensive printer.

The situation is a linear equation, and the equation that describes the situation is 2n + 1 = 253

How to determine the equation of the situation?

Let the smaller number be n.

So, the consecutive numbers are n and n + 1

When the numbers are added, we have:

Sum = n + n + 1

This gives

Sum = 2n + 1

The sum is 253.

So, we have:

2n + 1 = 253

Hence, the equation that describes the situation is 2n + 1 = 253

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial population P0 has doubled in 5 years. Suppose it is known that the population is 9,000 after 3 years.

Required:
a, What was the initial population P0?
b. How fast is the population growing at t = 10?

Answers

Step-by-step explanation:

Let the initial population of a community be P0 and the population after time t is P(t).

If the population of a community is known to increase at a rate proportional to the number of people present at time t, this is expressed as:

[tex]P(t) = P_0e^{kt}[/tex]

at t = 5 years, P(t) = 2P0

substitute:

[tex]2P_0 = P_0e^{5k}\\2 = e^{5k}\\ln2 = lne^{5k}\\ln2 = 5k\\k = \frac{ln2}{5}\\k = 0.1386[/tex]

If the population is 9,000 after 3 years

at t = 3, P(t) = 9000

a) Substitute into the formula to get P0

[tex]9000 = P_0e^{0.1386\times 3}\\9000 = P_0e^{0.4158}\\9000 = 1.5156P_0\\P_0 = \frac{9000}{1.5156}\\ P_0 = 5938.24[/tex]

Hence the initial population is approximately 5938.

b) In order to know how fast the population growing at t = 10, we will substitute t = 10 into the formula as shown:

[tex]P(10) = 5938.24e^{0.1386(10)}\\P(10) = 5938.24e^{1.386}\\P(10) = 5938.24(3.9988)\\P(10) = 23,745.97[/tex]

Hence the population of the community after 10 years is approximately 23,746

Enter your answer by filling in the boxes.

Answers

Answer:

[tex]\left[\begin{array}{ccc}-3&8&5\\-9&26&11\end{array}\right][/tex]

Step-by-step explanation:

Given the matrix A

[tex]\left[\begin{array}{ccc}-3&8&5\\-1&2&3\end{array}\right][/tex]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = -1

a₂₁ = -3R2+4R1

a₂₁ = -3(-1)+4(-3)

a₂₁ = 3-12

a₂₁ = -9

For a₂₂

If R1 = 8, R2 = 2

a₂₂ = -3R2+4R1

a₂₂ = -3(2)+4(8)

a₂₂ = -6+32

a₂₂ = 26

For a₂₃

If R1 = 5, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(5)

a₂₃ = -9+20

a₂₃ = 11

Hence the resulting matrix will be:

[ 8 -1   3]

We are to find the matrix that results from the elementary row operations represented by −3R2+4R1

R2 means row 2

R1 means row 1

Applying the elementary row operation will change the second row of the matrices.

For the first column, second row (a₂₁)

If R1 = -3, R2 = 8

a₂₁ = -3R2+4R1

a₂₁ = -3(8)+4(-3)

a₂₁ = -24-12

a₂₁ = -36

For a₂₂

If R1 = 5, R2 = -1

a₂₂ = -3R2+4R1

a₂₂ = -3(-1)+4(5)

a₂₂ = 3+20

a₂₂ = 23

For a₂₃

If R1 = 2, R2 = 3

a₂₃ = -3R2+4R1

a₂₃ = -3(3)+4(2)

a₂₃ = -9+8

a₂₃ = -1

Hence the resulting matrix will be:

[-3       5  2]
