Find the slope of the line

Answer:

Vanessa, she only needs to buy one ink cartridge according to the question

where Tia has to buy more? I need more info on the question

Step-by-step explanation:

Tia bought less expensive printer.

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.

Step-by-step explanation:

Did on edge

The solution to the equation is:

10° , 110° , 130°

Given,

cos(3x - 180) = -√3/2

Now,

To solve the trigonometric function,

cos(3x - 180) = -√3/2

Taking inverse of cos,

3x - 180° = [tex]cos^{-1} (-\sqrt{3}/2 )[/tex]

[tex]cos^{-1} (-\sqrt{3}/2 )[/tex] = 150°

3x - 180° = 150°

x = 10°

Hence the solutions of equation is the value of x that satisfies the relation .

x = {10° , 110° , 130° }

Answer:

A. y = square root of 2x

We are given the function

y = 2 √x

We are asked for the function that has the same domain as the given function

First, the domain for the given function is this

{ x | x ≥ 0 }

So, any function that has a domain of x that is equal to or greater than 0. Some examples:

f(x) = √x  -  2

f(x) = 5 √x

Step-by-step explanation:

The order of the numbers doesn't matter, so we'll use combinations instead of permutations.  The number of combinations is:

₄₅C₈ = 215,553,195

So the probability of a ticket having the winning combination is 1 / 215,553,195.

The expected value to the state is:

E(X) = 10,000 (1) ($2) + 10,000 (1 / 215,553,195) (-$1,000,000)

E(X) = $19954

The expected value to you is:

E(X) = 10,000 (1) (-$2) + 10,000 (1 / 215,553,195) ($1,000,000)

E(X) = -$19954

Hi, you've asked an incomplete question. The full question reads;

Because of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour. A research study will measure the cost of the new method over a sample production period.

a. Develop the null and alternative hypotheses most appropriate for this study.

b. Comment on the conclusion when H0 cannot be rejected.

c. Comment on the conclusion when H0 can be rejected

Explanation:

Remember, the null hypothesis usually represents the view the researcher has and that he wants to test or verify, while the alternative hypothesis refers to the opposite expected outcome.

a) Therefore, the null hypothesis is that the newly proposed manufacturing method will reduce the mean cost to lesser than $220.

While the alternative hypothesis is that the newly proposed manufacturing method will not reduce the cost to lesser than $220.

b) When H0 (null hypothesis) cannot be rejected, it means that indeed the research data proved to show that the newly proposed manufacturing method will reduce the mean cost to lesser than $220.

c) When H0 (null hypothesis) can be rejected it means that research data proved to show that the newly proposed manufacturing method would not reduce the mean cost to lesser than the current mean cost of $220.  Hence, the manager's proposal would not be accepted.

Answer:

Step-by-step explanation:

In order to get the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty, we need to calculate the power of the set having four elements. Let the set containing the element be A as shown;

Let set A = {a, b, c, d}

Power of the set P(A) = [tex]2^n[/tex] where:

n is the total number of element in the set. Since we have four elements in the set, n = 4

[tex]P(A) = 2^4\\P(A) = 16[/tex]

This means that the set A have 16 subsets. The subsets of the set are:

{}, {a}, {b}, {c}, {d}, {a, b}, {a, c}, {a, d}, {b, c}, {b, d}, {c, d}, {a, b, c}, {a, b, d}, {b, c, d}. {a, c, d}, {a, b, c, d}.

From all the subsets, it can be seen that intersection of set {a} and {b}, {a} and {c}, {c} and {d} are empty.

Hence the max number of 4-element-subsets of we can select, such that intersection of any 3 of them is empty is 16

I just took the quiz and I got it right

Statement describes how to geometrically divide a complex number z by a second complex number w is Option (C) Scale z by the reciprocal of the modulus of w, then rotate clockwise by the argument of w.

In mathematics, a complex number is an element of a number system that contains the real numbers and a specific element denoted i, called the imaginary unit

Modulus of the complex number is the distance of the point on the argand plane representing the complex number z from the origin

Given,

Complex number z divides by a second complex number w

To divide a complex number a complex number then multiply the conjugate with the numerator and the denominator of the complex fraction

From the given statements Scale of z by the reciprocal of the modulus of w, then rotate clockwise by the argument of w

Hence, Statement describes how to geometrically divide a complex number z by a second complex number w is Option (C) Scale z by the reciprocal of the modulus of w, then rotate clockwise by the argument of w.

Answer: Nearest hundredth

Step-by-step explanation:

Answer: 10 tulips, 10 lilies and 23 roses.

Step-by-step explanation:

Let's define the variables:

T = number of tulips that Jennifer bought

L = number of lilies that Jennifer bought

R = number of roses that Jennifer bought

Each tulip costs $0.18

Each lily costs $0.27

Each rose costs $0.55

We know that:

"She bought the same number of tulips as lilies."

T = L

" She bought three more roses than tulips and lilies combined."

R = T + L + 3

"she paid $17.15 in all"

T*$0.18 + L*$0.27 + R*$0.55 = $17.15

Then we have a system of 3 equations:

T = L

R = T + L + 3

T*$0.18 + L*$0.27 + R*$0.55 = $17.15

The first step to solve this is to replace the first equation into the other two, and get:

R = 2*L + 3

L*$0.18 + L*$0.27 + R*$0.55 = $17.15

Now we can replace the first equation into the second:

L*$0.18 + L*$0.27 + (2*L + 3)*$0.55 = $17.15

Now we can solve this for L.

L*($0.18 + $0.27 + 2*$0.55) + 3*$0.55 = $17.15

L*$1.55 + $1.66 = $17.15

L*$1.55 = $17.15 - $1.66 = $15.50

L = $15.50/$1.55 = 10

Then Jennifer bought 10 lilies.

And by the other two equations:

T = L = 10

She bought 10 tulips.

R = L + T + 3 = 10 + 10 + 3 = 23

She bought 23 roses

There is a sale tax on the item to be purchased, and the tax is 4.5% of the amount of the flag i.e 4.5% × $48.00 = $2.16

After the rate of the sale tax has been changed to dollars, we then add the amount of the sales to the amount of the flag to give the total amount to be paid i.e $2.16 + $48.00 = $50.16
