Answer: $49

Step-by-step explanation: 5% of 980 = 0.05 × 980 = 49

Answer:

$931

Step-by-step explanation:

Discount = less money paid

100% - 5% = 95%

95% = 0.95

980 * 0.95 = 931

Answer:

a = -b - c + 8

Step-by-step explanation:

8 = a + b + c.  Solve for a.

Subtract b from both sides

8 - b = a + c

Subtract c from both sides

8 - b - c = a

It is customary to rearrange so that the variable we solved for is on the left side

a = -b - c + 8

By using factor theorem it is obtained that,

x - 1 is not a factor f(x) =[tex]2x^5-9x-6[/tex]

What is factor theorem?

At first, it is important to know about remainder theorem

Remainder theorem states that if f(x) is divided by (x - a), then the remainder is f(a)

If the remainder is zero, then f(a) is a factor of f(x)

Factor theorem states that if f(a)  = 0, then (x - a) is a factor of f(x).

Here,

[tex]f(x)=2x^5-9x-6[/tex]

Divisor = x - 1

x - 1 = 0

x = 1

By remainder theorem,

Remainder = f(1)

f(1) =

Rochelle can make 2 party favors with 3/4 yards of wine.

According to the question,

We have the following information:

Rochelle had 3/4 yard of wine. Each party favor requires 3/8 yard.

Now, we will find how many parts of a party can 1 yard of wine favor using division.

So, we have the following expression:

1 party = 3/8 yards

1 yard = 8/3 party

Now, Rochelle has 3/4 yards of wine in total. So, we can find the number of party favors using multiplication.

3/4 yards = (3/4)*8/3

3/4 yards = 2 parties

Hence, Rochelle can make 2 party favors with 3/4 yards of wine.

In the making of 22 oz of bread rye flour and whole wheat requirements are 4.4 0z and 17.6 oz.

A ratio is a comparison between two quantities in simplest form.

A ratio of the from a : b can be written as a/(a + b) and b/(a + b).

Given, A recipe for whole grain bread calls for 1 oz of rye flour for every 4 oz of whole wheat flour.

∴ In the making of 22 oz of bread rye flour needed is 1/(1 + 4)×22

= (1/5)×22.

= 4.4 oz.

In the making of 22 oz of bread whole wheat needed is 4/(1 + 4)×22.

The probability that she will get the station between 9:25 and 9:30 is 1/2.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given: The time it takes a woman to travel from her apartment to the bus station follows a uniform distribution over the interval from 20 to 30 minutes.

She leaves home at 9:05 a.m.

Let x be the random variable denoting that travel time of a women from apartment to bus stop.

Here x ≈ U (20, 30)

⇒  F(x) = (x - 20) / (30 - 20)

To find, she leaves home at 9:25 at reach bus stop at 9:25 to 9:30

⇔ P(20 < x < 25)

First, let us understand the set:

A set is a mathematical model for a collection of different things; a set contains elements or members that can be any mathematical object: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets.

We are given;

A ⊂ B

We need to find A ∩ B.

Let us understand the given set;

A ⊂ B means A is a proper subset of B.

All the elements of set A are in set B.

So, A ∩ B = A

The largest possible total area of the four pens is 14,062.5 ft.²

What is the area?

A two-dimensional figure's area is the amount of space it takes up. In other terms, it is the amount that counts the number of unit squares that span a closed figure's surface. In general, square units such as square inches, square feet, etc. are used as the standard unit of area.

Diagrams illustrating the situation can be formed adjusting the width of the included diagram illustrating the general situation.

The expression for the total area is  A=( 150- (2Y)/5 ) Y

Reasons:

The given parameter are;

Length of fencing available = 750 ft.

Area to be enclosed = Rectangular

Number of included pens with parallel fencing = Four

Let Y represent the width of the area and let X represent the breadth

Therefore, we have;

2·Y + 5·X = 750

Which gives;

X=(750/5)-(2Y/5)=150-(2Y/5)

The area is therefore;

A=Y [150-(2Y/5)] = 150Y-(2Y²/5)

Differentiate with respect to Y and equate to zero

dA/dY = 150- (4Y/5)=0

Y=(150*5)/4 = 187.5

The width of the maximum area, Y = 187.5 ft.

Which gives;

X=150- (2*187.5)/5 = 75

The breadth of the area, X = 75 ft.

The maximum area,  = Y × X, which gives;

= 187.5 ft. × 75 ft. = 14,062.5 ft.²

Answer:

Step-by-step explanation:

You want the steps to writing the equation of a line parallel or perpendicular to a given line through a given point.

Given line ax+by=c and point (h, k), you can write equations for the desired lines using the forms:

  a(x -h) +b(y -k) = 0 . . . . . . parallel line

  b(x -h) -a(y -k) = 0 . . . . . . . perpendicular line

If you eliminate parentheses and collect terms, you will have the general form equation of the desired line(s). If you solve for y, you will have the slope-intercept form of the equation.

To use these forms, it is helpful to start with the equation of the given line in standard form, as shown. (It could also be in general form ax+by-c=0.)

Using the above solution, the steps are ...

You will note that the same coefficients are used on the same variables for a parallel line. This is because parallel lines have the same slope.

The coefficient of the variables are swapped, and one of them is negated in the equation for the perpendicular line. This is because perpendicular lines have opposite reciprocal slope.

When the given line is in slope-intercept form, y = mx +b, the slope is readily identified as m, the coefficient of x. For the parallel line, this slope can be used directly in the point-slope equation for a line through a given point:

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

This can be rearranged to the slope-intercept form:

  y = mx +(k -mh)

The perpendicular line has opposite reciprocal slope. The line perpendicular to the given line with slope m will have slope -1/m. Then the two forms of equation are ...

  y -k = -1/m(x -h) . . . . . . . . . point-slope form

  y = (-1/m)x +(k +h/m) . . . . . slope-intercept form

__

Additional comment

A standard form equation (ax +by = x) has mutually prime integer coefficients, with a positive leading coefficient. When you have written your equation, you may find it necessary to multiply the equation by some value to put it in this form. For example, -2x +4y = -8 must be multiplied by -1/2 to get the standard form equation x -2y = 4.

You need to be aware of the form required by your grader. The wording "the equation" often means slope-intercept form, or the form matching the given equation or the answer box format.

Assuming that other factors are held constant, the sample means difference Increases. (option C)

The null hypothesis and the alternative hypothesis are the two types of hypotheses for a test.

Step 1: The null hypothesis is based on the assumption that there is no difference between the true mean (µ) and the compare value ([tex]m_{o}[/tex]). The alternative hypothesis is based on this assumption.

Step 2: Increasing the sample mean difference would probably make it more likely that the null hypothesis will be rejected, as long as other factors stay the same.

From the given mean and standard deviation the closest minimum annual profit, for a store that had a reward party is equal to $102,300.

As given in the question,

Given distribution of annual profit :

Approximately normal with mean μ = $66,000

Standard deviation σ = $22,000

Profits in the top 5 percent

Apply z-score formula :

z = ( x - μ) / σ

Top 5% mean 95% and more.

Using normal distribution table,

z -score corresponding to 95% or 0.95 is equal to 1.65.

Substitute all value in the formula we get,

1.65 = ( x - 66,000 ) / 22,000

⇒ x - 66,000 = 1.65 × 22,000

⇒ x = 36,300 + 66,000

⇒ x = 102,300

Therefore, from the given mean and standard deviation the closest minimum annual profit, for a store that had a reward party is equal to $102,300.
