So with the expression 3 + 4 x 3 - 3 x 5 we know to multiply first. So let's multiply 4 x 3 and -3 x 5 first:

3 + 4 x 3 - 3 x 5

= 3 + 12 - 15

Then let's work out the rest of the expression!

3 + 12 - 15

= 15 - 15

= 0

Therefore we can determine that 3 + 4 x 3 - 3 x 5 = 0

Answer:

Below in bold.

Step-by-step explanation:

R(x) = 8x/(x + 19)

When x = -19 the denominator = zero so there is a vertical asymptote which is

x = -19.

If we divide 8x by x + 19 we get  8 remainder -152.

So horizontal asymptote is R(x) = 8.

As the degree of the numerator and denominator are the same ( both 1) there is no oblique asymptote.

Answer:

a) Revenue function = 1.299r + 1.379p

where: r = gallon of unleaded regular gasoline and p = gallon of regular unleaded premium gasoline

b) cost function = 1.219f + 1.289p

c) profit function = (1.299r + 1.379p) - (1.219f + 1.289p) = 1.299r - 1.219r + 1.379p - 1.289p = 0.08p + 0.09p

d) total profit = (0.08 x 100,000) + (0.09 x 40,000) = $8,000 + $3,600 = $11,600

The mean of this probability distribution is 1.55.

To find the mean of a probability distribution, we need to multiply each possible value by its corresponding probability, and then add up these products. So, the mean is:

mean = (0)(0.19) + (1)(0.37) + (2)(0.16) + (3)(0.26) + (4)(0.02)
    = 0 + 0.37 + 0.32 + 0.78 + 0.08
    = 1.55

Therefore, the mean of this probability distribution is 1.55.

Linear regression is a technique used in statistics and machine learning to understand the relationship between two variables and how one affects the other.

In this case, we are interested in understanding the relationship between sales and seasonality. We can use linear regression to create a model that predicts sales based on seasonality. Here's how we can do it First, let's plot the data to see if there is a relationship between sales and seasonality.

We can see that there is a clear pattern that repeats every year. This indicates that there is a strong relationship between sales and seasonality. We can use the following equation: y = mx + b, where y is the dependent variable (sales), x is the independent variable (seasonality), m is the slope of the line, and b is the intercept of the line.

Answer:

When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. In general if r represents the growth or decay factor as a decimal then: b = 1 - r Decay Factor. b = 1 + r Growth Factor. A decay of 20% is a decay factor of 1 - 0.20 = 0.

Step-by-step explanation:

The growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

It is defined as the factor that represents the increase and decreases in value by that factor. For the growth add one as a decimal and for the decay subtract one as a decimal.

For the growth factor:

F(g) = 1+r

Here r = 24% = 0.24

F(g) = 1+0.24 = 1.24

For the decay factor:

F(d) = 1-r

Here r = 24% = 0.24

F(d) = 1-0.24 = 0.76

Thus, the growth factor is 1.24, and the decay factor is 0.76 for the 24% growth add one as a decimal and for decay subtract one as a decimal.

The volume of the right prism with a base area of 10 square feet and a height of 6 feet is 60 cubic feet.

A prism is a polyhedron that has a base and a top face that are the same in size and shape, with sides connecting them that are rectangles in a right prism.

A right prism is a prism in which all of the side faces are perpendicular to the base.

Therefore, the height of the right prism is perpendicular to the base as well.

A right prism has a volume equal to the product of the base area and the height.

This formula can be represented as:

V = Bh

Here, B represents the area of the base, and h represents the height.

The volume of the right prism can be found by multiplying the area of the base by the height of the prism, according to the formula:

V = Bh.

In this problem, the area of the base of the prism is given to be 10 square feet.

The height of the prism is 6 feet.

We can simply substitute these values into the formula to obtain the volume of the right prism as follows:

V = BhV

   = 10 × 6V

   = 60

Therefore, the volume of the right prism is 60 cubic feet.

Answer:

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

Both company 1 and 2 charge $153.75 for cleaning 25 garment

Step-by-step explanation:

Equation 1

\(\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55\)

y-62.75=4.55(x-5)

y-62.75=4.55x-22.75

c(n)=4.55x + 40

Equation 2

\(\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75\)

y-38.75=5.75(x-5)

y-38.75=5.75x-28.75

c(n)=5.25x + 10

The system will be

f(x)=4.55x+40

g(x)=5.75x+10

30=1.2x

x=25

Answer:

The answer is 1/3.

Answer: She should run 1 1/3 miles 5 times a week.

Step-by-step explanation:  I converted 3/4 to a decimal to have 1.75 and I multiplied it by 5 because that is how many times she will be running 1.75 miles in a week, I got 8.75. So that means if she runs 1.75 miles for 5 days she will run a total of 8.75 miles. Then I converted 1/4 into a decimal and now have 2.25, then I multiplied 2.25 by 3 and got 6.75. So I saw that 8.75 is greater than 6.75,

So the correct answer is: she should run 1 3/4 miles 5 times a week

The zeros of the quadratic function f(x) = 8x² - 16x - 15 are x = 1 – and x = 1.A quadratic function is a type of polynomial function where the highest exponent of the variable (usually x) is 2.

In the standard form of a quadratic function, it is represented by f(x) = ax² + bx + c, where a, b, and c are constants.How to find the zeros of a quadratic function, The zeros of a quadratic function can be found by solving the quadratic equation ax² + bx + c = 0. The solutions of the quadratic equation are the x-intercepts or the zeros of the quadratic function. In the given quadratic function, f(x) = 8x² - 16x - 15, a = 8, b = -16, and c = -15.

Answer : y = - 8

3/4y+6=0

Step 1: Subtract 6 from both sides :

3/4y + 6 - 6 = 0 - 6

3/4y = -6

Step 2: Multiply both sides by 4/3 :

( 4/3 ) × ( 3/4y ) = ( 4/3 ) × ( -6 )

Final answer is y = - 8

At least 68% of the data falls between 62 and 78, and at least 95% of the data falls between 54 and 86.

To answer this question, we can use the empirical rule, also known as the 68-95-99.7 rule, which tells us that for a normal distribution:

Using this rule, we can estimate the fraction of the data that falls between the following pairs:

Between 54 and 86:

To find the range of values that is within two standard deviations of the mean, we can subtract and add two standard deviations from the mean:

Lower bound: 70 - 2*8 = 54

Upper bound: 70 + 2*8 = 86

So, about 95% of the data falls between 54 and 86.

Between 62 and 78:

To find the range of values that is within one standard deviation of the mean, we can subtract and add one standard deviation from the mean:

Lower bound: 70 - 8 = 62

Upper bound: 70 + 8 = 78

So, about 68% of the data falls between 62 and 78.

Therefore, we can conclude that at least 68% of the data falls between 62 and 78, and at least 95% of the data falls between 54 and 86.
