Answer:

y = x - 12

Step-by-step explanation:

slope = (-9 - (-5))/(3 - 7) = -4/(-4) = 1

y = mx + b

y = x + b

-5 = 7 + b

b = -12

y = x - 12

Answer:

145 degrees

Step-by-step explanation:

The side through L is at a 35 degree angle, and the side through N is at a 180 degree angle. Taking the difference, we get 145 degrees.

Lower Limit = 24.52

Upper Limit = 36.28

Error Bound = 5.88

Lower Limit: - The Lower Limit for every class is the smallest value in that class. For example: 5 is a lower lower limit for the set S= { 5,8,42,34}

Upper Limit: - A value that is greater than or equal to every element of a set of data. For example: - { 3,5,11,20,22} is a upper bound of 22.

Given that,

Population Mean,μ = 33.2

sample Mean, χ (x bar) = 30.4

sample Size, n = 25

α (Alpha) = 0.05

Population standard deviation,σ = 15

95% confidence interval:

μ ± z critical σ / √n

Putting the values, we get,

z critical at α0.05 = ± 1.96

30.4 ±1.96( 15/√25) = 30.4 ± 5.88 = (24.52,36.28)

a) Lower Limit = 24.52

b) Upper Limit = 36.28

c) Error Bound =

Margin of Error = z critical × σ /√n

                         =  1.96 × 15/√25

                          = 1.96  × 15/5

                          = 5.88

The possible numbers of additional miles that Lamar can run are all the solutions of the inequality:

0 ≤ x ≤ 15

We know that Lamar will run at most 37 miles this week, and he already did run 22 miles, then the (maximum) distance left this week is:

D = 37mi - 22mi = 15mi

So he can run at most 15 miles, this means that he can run any distance between 0 miles and 15 miles by the end of the week.

So, if we define x as the distance that he will run on the week (in miles), then we can write the inequality:

0 ≤ x ≤ 15

so the possible numbers of additional miles he will run on this week are all the values of x that are a solution for the above inequality.

2/5 fraction as a decimal is 0.4.

Any number that is expressed as a fraction has two components, the numerator and the denominator. Typically, we divide the numerator by the denominator to convert a fractional number to decimal form. The formula p/q, where q=0, is used to denote fractions. While the decimal numbers, such as 7.575, are created by joining the entire number and fractional parts with a decimal point. 

There are two methods to convert fraction to decimal which are given below:

For 2/5

We will divide them as mentioned above,

El precio final, esto es, el precio con descuento, del bolso es igual a $ 36.000.

En este problema debemos determinar el precio final de un bolso (C') adquirido por un cliente con descuento, igual al precio original (C) menos el descuento, descrito en la siguiente fórmula:

C' = C · (1 + r / 100)

Donde r es la tasa de descuento. Nótese que existe descuento para 0 < r < 100.

Si sabemos que C = 40.000 y r = - 10, entonces el precio final del bolso es:

C' = 40.000 · (1 - 10 / 100)

C' = 36.000

Caroline would have $36 more money in her account than Jaxon.

From the question, we have

Caroline amount,

A = P* e^rt

= 900*e^(71/100)

=$1830.59

Jaxon amount,

A = P* e^rt

= 900*e^(69*8)/800

= 900*e^(69/100)

Subtraction:

Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.

The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

The option that shows the equation for the line in the graph is

A graph is a pictorial representation of data. The graph shows a linear function which will be written in the slope intercept form  form as

y = mx + c

where

m = slope

c = intercept

x = input variables

y = output variables

calculation of slope

The points used for the slope is gotten from the graph as B(-5. 5)  (-2, -4)

m = (y₂ - y₁) / (x₂ - x₁)

substituting the values

= ( -4 - 5 ) / ( -2 - -5 )

= -9 / -2 + 5

= -9 / 3

= -3

y intercept, c

this is a point where the graph cuts the y axis

c = -10

hence the equation is written using y = mx + c and substituting the values

y = -3x - 10

1) [tex]1.4^{2}[/tex] is really just 1.4 * 1.4, which you can solve by long multiplication or a calculator to get 1.96

2) for this one, you can rewrite the expression as a fraction. you'll also want to use PEMDAS, starting with the parentheses

[tex]\frac{300}{ 2(0.5+4.5)^{2}}\\\\\frac{300}{2*(5)^2}\\\\\frac{300}{2*25} \\\\\frac{300}{50} = 6[/tex]

3) [tex](\frac{1}{2})^{3} = \frac{1}{2} *\frac{1}{2} *\frac{1}{2} = \frac{1}{8} \\[/tex]

you can rewrite the division as a fraction again, only this time. you can change the subtraction to the reciprocal of the denominator

The given function are

r(x) = 2 - x²    and     w(x) = x - 2

(w*r)(x) can be obtained by multiplying the both function together

So, (w*r)(x) = w(x) * r(x) = (x-2)*(2-x²)

(w*r)(x) = x (2-x²) - 2(2-x²)

           = 2x - x³ - 4 + 2x²

∴ (w*r)(x) = -x³ + 2x² + 2x - 4

It is a polynomial function with a domain equal to R

The range of (w*r)(x) can be obtained by graphing the function

To graph (w*r)(x), we need to make a table between x and (w*r)(x)

See the attached figure which represents the table and the graph of (w*r)(x)

As shown in the graph the range of (w*r)(x) is (-∞,∞)

The price range of the Chevrolet HHR retro will be $14,500.

The range of the data is defined as the difference between the maximum value of data and the minimum value of the data.

The given data as:

$8,500, $8,500, $8,500, $9,900, $10,800, 10,800, 11,000, 12,500, $12,500, $13,000, 13,000, $14,500, and $23,000

According to the given information, the required solution would be as:

The maximum value of data = $23,000

The minimum value of data = $8,500

The range of the data = The maximum value of data - The minimum value of data

Substitute the values in the above formula,

The range of the data = 23,000 - 8,500

Apply the subtraction operation to get the answer

The range of the data = 14,500

The compound interest earned by Evelyn in one year is $9.

Evelyn has a bank account. She deposited $90 in her account. She earns 10% interest on her deposited money. The interest earned is compounded annually. We need to calculate the interest earned by her in one year, to the nearest cent.

We need to calculate the compound interest. The formula is given below.

B = p(1 + r)^t

The variables 'B', 'p', 't', and 'r' represent the final amount, the initial amount, the time duration, and the rate of interest, respectively.

B = $90(1 + 0.1)^1

B = $90*1.1

B = $99

The final amount in her bank account after one year is $99. The interest earned is the difference between the final and the initial amount. Let the variable 'I' represent the interest earned.

I = B - p

I = $99 - $90

I = $9
