Write the slope-intercept form of the equation for each line.

Answers

Answer 1

Answer: y=4/5x-1.5

Step-by-step explanation: slope intercept form is y=mx+b

m is going to be the slope of the line which in this case is 4/5 (rise over run)

b is going to be where the line intercepts the y-axis, in this case it looks to be at -1.5. Since the y-intercept is in the negatives, we subtract b.

x is an just a variable to be added in for if/when this equation is used.

Suppose that approximately 273,000,000 people live in the United States. Of these people, 31,200,000 speak a language other than English at home. Of those who speak another language at home, over 50 percent speak Spanish.
• E = speak English at home

Answers

The required probability is given by P(E') =4/35 .

Probability is the study of chance. It can also be defined as the ratio of the favorable outcomes to an event to the total number of outcomes of the event.

Given the total number of people in the USA = 273000000

Let E be the number of people who speak English at home.

Therefore the number of people who don't speak English at home is E'.

∴ E' = 31200000

S speak Spanish in their homes.

∴ S = 50% of 31200000 = 15600000

Now let us find the required probabilities.

We know that probability = favorable outcome ÷ total outcome

total outcome = 273000000

a) favorable outcome(E') = 31200000

P(E')=31200000/273000000

P(E') =4/35

b)favorable outcome(E) = 273000000 - 31200000 = 241800000

P(E) = 241800000/273000000

P(E)={31}/{35}

c)favorable outcome = 15600000

P(S)={15600000}/{273000000}

P(S)={2}/{35}

Therefore the required probability is given by P(E') =4/35 , [tex]P(E)=\frac{31}{35}[/tex] P(E)=31/35 and P(E)=2/35and .

The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). The cost for using 14 HCF of water is $32.62 , and the cost for using 48 HCF is $78.52 . What is the cost for using 40 HCF of water?

Answers

The cost for using 40 HCF of water is $67.72

What is the cost for using 40 HCF of water?

To solve this question, we use the following representations

x represents HCFy represents the amount

Using the above representations, we have the following points

(x, y) = (14, 32.62), (48, 78.52)

For 40 HCF of water, we have

(x, y) = (40, y)

The slope of a linear equation is calculated using

m = (y2 - y1)/(x2 - x1)

So, we have

m = (78.52 - 32.62)/(48 - 14) = 1.35

m = (78.52 - y)/(48 - 40)

Substitute m = 1.35 in m = (78.52 - y)/(48 - 40)

So, we have:

1.35 = (78.52 - y)/(48 - 40)

Evaluate the difference

1.35 = (78.52 - y)/8

Multiply both sides by 8

10.8 = 78.52 - y

This gives

y = 78.52 - 10.8

Evaluate the difference

y = 67.72

Hence, the cost for using 40 HCF of water is $67.72

What is the probability that the customer is at least 30 but no older than 60?

What is the probability that the customer is either older than 60 or younger than 40?

What is the probability that the customer is at least 60?

Answers

The probability that the customer is at least 30 but no older than 60 is o.45, that the customer is either older than 60 or younger than 40 is 0.68 and that the customer is at least 60 is 0.22.

We have the data:

Age Number of Customers

< 20 78

20 - 30 58

30 - 40 53

40 - 50 77

50 - 60 52

> 60 91

The probability that the customer is at least 30 but no older than 60 will be:

P = 182 / 409

P = 0.45

The probability that the customer is either older than 60 or younger than 40 will be:

P = 280 / 409

P = 0.68

The probability that the customer is at least 60 will be:

P = 91 / 409

P = 0.22

Therefore we get the probability that the customer is at least 30 but no older than 60 is o.45, that the customer is either older than 60 or younger than 40 is 0.68 and that the customer is at least 60 is 0.22.

A sample of ore is found to be 0.0022% gold and 0.059% diamond. What is the percentage of matter in the ore that is neither gold nor diamond? Round your answer to the nearest ten thousandth.

Answers

The percentage of matter in the ore that is neither gold nor diamond is 99.9388%.

In the question, we are given that a sample of ore is found to be 0.0022% gold and 0.059% diamond.

We are asked for the percentage of matter in the ore that is neither gold nor diamond.

We know that in any quantity, the total is shown as 100%.

If we assume the percentage of matter in the ore that is neither gold nor diamond to be x%, then using the above theory, we can say that;

x% + 0.0022% + 0.059% = 100%.

This can also be shown as:

x + 0.0022 + 0.059 = 100, which can be simplified as:

x + 0.0612 = 100, which can be solved by subtracting 0.0612 from both sides to get:

x = 100 - 0.0612 = 99.9388‬.

Thus, the percentage of matter in the ore that is neither gold nor diamond is 99.9388%.

The value of ab = 1 in the two given equations with no solutions.

What do we mean by equations with no solutions?When the two lines are parallel, a system of two linear equations in two variables has no solution. In terms of algebra, this means that when we solve the system, we get a false equation. On a graph, the lines never intersect because they have the same slope but different y-intercepts. There will be no solution if (a₁/a₂) = (b₁/b₂) (c₁/c₂). This is referred to as an inconsistent pair of linear equations.

So, it is said that the two equations (ax - y = 0) and (x - by = 1) have no solutions.

Answers

The equation that models the balance y after x months is given by y = 1500 -150x,

Apparently, we have to assume that the balance is a linear function of the number of months that the payment is boing made.

We are given 3 points:

(0, 1500), (6, 600) and (8, 300)

Any two of these can be used to write the equation of the line :

y = (y₂ - y₁) / (x₂ - x₁) (x - x₁) + y₁

y = (600 - 1500) / (6 - 0) (x - 0) + 1500

y = - 900 / 6 x + 1500

The points I, J, K and L all lie on the same line segment, in that order, such that the ratio IJ:JK:KL is equal to 2:5:5 IfIL=60, find KL.

Answers

The length of KL with the given ratio is 25 units

How to determine the length of KL?

The given parameters are:

IJ : JK : KL is equal to 2 : 5 : 5

IL = 60

Rewrite properly as:

IJ : JK : KL = 2 : 5 : 5

This means that the length of KL

KL = KL ratio/Sum of ratios * IL

So, we have

KL = 5/(2 + 5 + 5) * 60

Evaluate the sum

KL = 5/12* 60

Divide 60 by 12

So, we have

KL = 5 * 5

Evaluate the product

KL = 25

Hence, the length of KL with the given ratio is 25 units
