Find the slope of the line by comparing the change in y to the change in x.

Answer:

B

Step-by-step explanation:

so your starting value (10) is not going to have the x by it. instead he is feeding his dog so it will be subtracted from.

x is the number of days he can feed his dog. this will be mulitplied with something.

0.5 is how much he feeds his dog each day. this will be times the number of days or x.

so it makes your answer [tex]y=10-0.5x[/tex]

Step-by-step explanation:

Morgan's approximate APR is approximately 1.0%.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the given formula:

Approximate APR = (Finance Charge ÷ Months) x 12 / Amount Financed

We know that the amount financed is the total cost of the sofa minus the finance charge, which is:

Amount Financed = $216.00 - $25.00 = $191.00

We also know that the finance charge was $25.00 and she paid for it over 15 months, so:

Finance Charge ÷ Months

= $25.00 ÷ 15

= $1.67

The approximate APR is:

Approximate APR = ($1.67 x 12) ÷ $191.00 = 0.1393

Rounding this to the nearest tenth gives us 0.1, which is equivalent to 1.0% as the nearest percentage.

Therefore,

Morgan's approximate APR is approximately 1.0%.

Answer:

450 x 1.08 ^ X = N

Step-by-step explanation:

Since in 2002, there were 450 households in the city of Klean that recycled, and each year since 2002, the number of households that recycle has grown by 8%, to write a function to represent the number of households in Klean that recycle X years since 2002 the following mathematical reasoning should be raised:

450 (initial number) x 1.08 (8% is added to the initial number) ^ X (years) = Number of households that recycle

450 x 1.08 ^ X = N

Thus, for example, if said number were calculated in 2007, that is, 5 years after 2002, the equation would apply as follows:

450 x 1.08 ^ 5 = N

450 x 1.4693 = N

661.20 = N

Answer:

If a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Step-by-step explanation:

Taking into account the educational table provided, if a resident who is 30-49 years old is chosen at random, to determine what is the probability that they have completed a bachelor's degree and no more the following calculation must be performed:

30-39 Bachelor's degree = 1576

40-49 Bachelor's degree = 443

30-39 Total = 4062

40-49 Total = 2869

4062 + 2869 = 100

1576 + 443 = X

6931 = 100

2019 = X

2019 x 100/6931 = X

201900/6931 = X

29,129 = X

Therefore, if a resident who is 30-49 years old is chosen at random, the probability that they have completed a bachelor's degree and no more is 29.13%.

Answer:18

Step-by-step explanation:

18 inches represent 225 miles.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

Given that,

2 inches on a map represents 25 miles.

We have to calculate the value of inches that correspond to 225 miles.

Let x be the unknown value of inches that correspond to 225 miles.

Using proportional concept,

2 : 25 = x : 225

This can also be written as,

2 / 25 = x / 225

Cross multiplying,

2 × 225 = 25 x

x = (2 × 225) / 25

x = 18

Hence the value of the unknown inch is 18 inches.

Answer:

H0 : σ²= 7.2²

H1 : σ² < 7.2

We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Step-by-step explanation:

H0 : σ²= 7.2²

H1 : σ² < 7.2²

The test statistic :

X² = [(n - 1)*s² ÷ σ²]

s² = 3.5

n = sample size = 25. ; s²

X² = [(25 -1)*3.5² ÷ 7.2²

X² = (24 * 3.5^2) / 7.2^2

X² = 5.67

Pvalue from Chisquare statistic :

P(X² < 5.67) = 0.000042

Pvalue < α ; we reject the Null.

Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Step-by-step explanation:

|-7| - |-3 1/2| = 3 1/2

Step-by-step explanation:

The endpoints of the diameter are A(-4,1) and B(4,2) . For finding the equation of circle we need to find the centre and the radius.

Coordinates of centre can be find out by the midpoint formula.

[tex] \implies Center = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\implies Centre = \bigg(\dfrac{-4+4}{2},\dfrac{1+2}{2}\bigg)\\\\\implies \boxed{\boxed{Centre = (0 , 1.5)}}[/tex]

Now the measure of radius can be obtained by half the distance between them.

[tex]\implies D = \sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\implies D =\sqrt{ (4+4)^2+(2-1)^2}\\\\\implies D = \sqrt{ 64 + 1 }\\\\\implies D =\sqrt{65} \\\\\implies \boxed{\boxed{ Radius = \dfrac{\sqrt{65}}{2} }}[/tex]

We know the general equation of circle as ,

[tex]\implies (x-h)^2+(y-k)^2= r^2[/tex]

[tex]\implies (x-0)^2+ (y-1.5)^2 = \bigg(\dfrac{\sqrt{65}}{2} \bigg)^2\\\\\implies x^2 + (y-1.5)^2=\dfrac{65}{4} \\\\\implies\boxed{\boxed{ 4x^2+4(y-1.5)^2 = 65 }}[/tex]
