Find the slope of the line through the pair of points: ( − 3 , 4 ) and ( 0 , 2 ) .

Answers

Answer 1

Answer:

[tex]-\frac{2}{3}.[/tex]

Step-by-step explanation:

1) the required slope can be calculated if to use the ratio:

slope=(y(B)-y(A))/(x(B)-x(A)), where x(A)=-3; y(A)=4; x(B)=0 and y(B)=2;

2) according to the formula above:

s=(2-4)/(0+3)=-2/3.

Answer 2

The slope of the line through the given points is: -2/3.

What is the Slope of a Line?

Slope of a line= change in y / change in x = rise/run.

Given the points:

(-3, 4) = (x1, y1)

(0, 2) = (x2, y2)

Slope = (4 - 2)/(-3 - 0)

Slope = 2/-3

Slope of the line = -2/3

ASpoon is sold at a loss of 47%. If it was sold at 200
Calculate the Cost Price

Answers

Answer:

377.36(2decimal places)

Step-by-step explanation:

Solution

First write down all known info about problem

Loss(L) percent:47%

Selling price(SP):200

Cost Price is unknown but CP percent equals 100%(basic percent b'cos it represents the basic cost of the item)

When at a loss, the CP is higher than the SP so subtract the L% from the CP% to get the SP percent...

∴SP% equals CP%-L%

100%-47%:53% ∴SP%:53%

We can simply cross multiply now by saying,

If 53% equals 200

∴100% equals a variable(x)

Cross multiplying,we get:

53x equals (200×100) so dividing both sides by 53,

x equals 377.36(2 decimal places)

Therefore, the CP is 377.36

hope helpful~

Answer:

Value of k is 74

Step-by-step explanation:

Here we have been provided with the values of n and w that is 4 and -6 respectively.

Equation that we have,

k = 5n² + w

Substituting the values of n and w in the equation,

[tex] \implies \: \sf{k \: = \: 5(4) {}^{2} \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 5(4 \times 4) \: + \: ( - 6)}[/tex]

[tex] \implies \: \sf{k \: = \: 5 \: (16) \: + \: ( - 6)}[/tex]

Multiplying 16 by 5,

[tex]\implies \: \sf{k \: = \: 5 \: \times 16 \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 80 \: + \: ( - 6)}[/tex]

[tex]\implies \: \sf{k \: = \: 80 \: - \:6)}[/tex]

Subtracting 6 from 80,

Amount got as help;

An academic scholarship of $8,200.

Other scholarships and grants of $7.400.

Grandparents pay $1,000

Find the producer's surplus at market equilibrium for a product if its demand function is p = 121 − [tex]x^{2}[/tex] and its supply function is p = [tex]x^{2}[/tex] + 6x + 65. (Round your answer to the nearest cent.)

Answers

The market equilibrium is the point where the demand and supply functions are equal

The producer's surplus at market equilibrium for a product is #105

How to determine the producer's surplus

The functions are given as:

[tex]p = 121 - x^2[/tex]

[tex]p = x^2 + 6x + 65[/tex]

Equate both functions

[tex]x^2 + 6x + 65 = 121 - x^2[/tex]

Collect like terms

[tex]x^2 + x^2 + 6x + 65 - 121 = 0[/tex]

Evaluate the like terms

[tex]2x^2 + 6x -56 = 0[/tex]

Divide through by 2

[tex]x^2 + 3x -28 = 0[/tex]

Expand

[tex]x^2 + 7x - 4x - 28 = 0[/tex]

Factorize

[tex]x(x + 7) - 4(x +7)= 0[/tex]

Factor out x + 7

[tex](x - 4)(x +7)= 0[/tex]

Solve for x

x = 4 or x = -7

The number of units cannot be negative,

So, we have:

x = 4

Substitute 4 for x in [tex]p = 121 - x^2[/tex]

[tex]p = 121 - 4^2[/tex]

p = 105

Hence, the producer's surplus at market equilibrium for a product is #105

Graphing an interger function and finding its range for a given domain

Answers

For the function and given domain, the range is  {-9,-1,5,7}.

Linear Function

A linear function can be represented by a line. The standard form for this equation is: [tex]y=ax+b[/tex], for example, y=2x+7.

Domain and Range

The domain of a function is the set of input values for which the function is real and defined. On the other words, when you define the domain, you are indicating for which values x the function is real and defined.

While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

The equation of this exercise, 2x+1,  is a linear equation because it presents the form: ax+b. Thus, you already know that your graph will be a line.

Find values of y for given domain:

For this, you should replace -5,-1, 2,3 for x in the equation 2x+1.

For x=-5,  [tex]y=2*(-5)+1=-10+1=-9[/tex]

For x=-1, [tex]y=2*(-1)+1=-2+1=-1[/tex]

For x=2, [tex]y=2*(2)+1=4+1=5[/tex]

For x=3, [tex]y=2*(3)+1=6+1=7[/tex]

Therefore, the range is {-9,-1,5,7}

A scientist mixes water (containing no salt) with a solution that contains 20% salt. She wants to obtain 140 ounces of a mixture that is 5% salt. How many ounces of water and how many ounces of the 20% salt solution should she use?

Answers

Let x represent ounces of water.
Ounces of 30% salt solution required = 140 - x

(Percentage of salt solution)(ounces of 30% solution required) = (5% salt solution needed)(extra salt solution needed)

(20/100)(140-x) = (5/100)*140
(1/5)(140-x) = (1/20)*140
28-1/5x = 7
Multiply both sides of the equation by 5 to isolate x:
5*(28-1/5x = 7)*5
140-x = 35
-x = 35 - 140
-x = -105
x = 105

Ounces of salt solution = 140 - 105 = 35

Therefore, 105 ounces of water is required and 35 ounces of salt solution is required

The average number of words in a romance novel is 64,436 and the standard deviation is 17,071. Assume the distribution is normal. Let X be the number of words in a randomly selected romance novel. Round all answers to 4 decimal places where possible.

a. What is the distribution of X? X ~ N(
64436
Correct,
17071
Correct)

b. Find the proportion of all novels that are between 72,972 and 90,043 words.


c. The 75th percentile for novels is
words. (Round to the nearest word)

d. The middle 60% of romance novels have from
words to
words. (Round to the nearest word)

Answers

b. You're looking for the probability

Pr [72,972 ≤ X ≤ 90,043]

Transform X to Z ∼ Normal(0, 1) using the rule

X = µ + σ Z

with µ = 64,436 and σ = 17,071. Then the probability is

Pr [(72,972 - µ)/σ ≤ (X - µ)/σ ≤ (90,043 - µ)/σ]

≈ Pr [0.5000 ≤ Z ≤ 1.5000]

You probably have a z-score table available, so you can look up the probabilities to be about

Pr [Z ≤ 0.5000] ≈ 0.6915

Pr [Z ≤ 1.5000] ≈ 0.9332

and then

Pr [0.5000 ≤ Z ≤ 1.5000] ≈ 0.9332 - 0.6915 = 0.2417

c. The 75th percentile word count that separates the lower 75% of the distribution from the upper 25%. In other words, its the count x such that

Pr [X ≤ x] = 0.75

Transforming to Z and looking up the z-score for 0.75, we have

Pr [(X - µ)/σ ≤ (x - µ)/σ] ≈ Pr [Z ≤ 0.6745]

so that

(x - µ)/σ ≈ 0.6745

x ≈ µ + 0.6745σ

x ≈ 75,950

d. Because the normal distribution is symmetric, the middle 60% of novels have word counts between µ - k and µ + k, where k is a constant such that

Pr [µ - k ≤ X ≤ µ + k] = 0.6

Also due to symmetry, we have

Pr [µ - k ≤ X ≤ µ + k] = 2 Pr [µ ≤ X ≤ µ + k]

⇒   Pr [µ ≤ X ≤ µ + k] = 0.3

Transform X to Z :

Pr [(µ - µ)/σ ≤ (X - µ)/σ ≤ (µ + k - µ)/σ] = 0.3

⇒   Pr [0 ≤ Z ≤ k/σ] = 0.3

⇒   Pr [Z ≤ k/σ] - Pr [Z ≤ 0] = 0.3

⇒   Pr [Z ≤ k/σ] - 0.5 = 0.3

⇒   Pr [Z ≤ k/σ] = 0.8

Consult a z-score table:

Pr [Z ≤ k/σ] ≈ Pr [Z ≤ 0.8416]

⇒   k/σ ≈ 0.8416

⇒   k ≈ 14,367

Then the middle 60% of novels have between µ - k = 50,069 and µ + k = 78,803 words.
