The percent of the purchase price that the sales price is 80%.

The number of jackets that should sold so that total sales can be at least $260 is 6.

The equation that can be used to determine the percent of the purchase price the sales price is:

Percent = (sale price / purchase price) - 1

($72 / $40) - 1 = 0.80 = 80%

The sales price of the $25 jackets if prices are increased by 80%

Sales price = (1 + percent) x purchase price

(1 + 0.8) x $25

1.8 x $25 = $45

The number of jackets to sell so that total jacket sales can be at least $260 is:

(sales price per jacket x number of jackets) ≥ $260

($45 x j) ≥ $260

$45j ≥ $260

j ≥ $260 / $45

j ≥ 5.8 ≈ 6

The probability that a person gets there in less than 3 minutes on at least 4 of the next 6 days is 0.3969.

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities. By dividing the number of positive outcomes by the entire number of possible outcomes, probability—the likelihood that an event will occur—is determined. The most basic illustration is a coin toss. There are only two outcomes when you flip a coin: either it comes up heads or tails.

Given,

Mean = 4 minutes

= 1/4

= 0.25

The probability that someone will be attended to in less than three minutes on any given day is:

P( X ≤3)

= 1- e⁻⁰²⁵⁽³⁾

= 0.5267

The probability is:

P( X ≥ 4)

= P( X = 4) +P( X = 5 ) + ( X = 6)

= 0.2594 + 0.1159 + 0.216

= 0.3969

Equations B and D are true.

The equation of line parallel to the given line is found as y = -6x + 13.

The equation of the line is-

y = -6x + 1

The second line is parallel to the above line, thus the slopes of both the line are equal.

m1 = m2 = -6

The new line also passes from the point (1, 7)

(x1, y1) = (1,7)

Thus, the equation of the line will be calculated as-

y - y 1 = m2(x - x1)

y - 7 = -6(x - 1)

y - 7 = -6x + 6

Solve for f by simplifying both sides of the equation, then isolating the variable.

The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.

We have following information,

the demand for the polymer is distributed normally .

Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons

Selling price of poymer = $25 per gallons

cost price of raw material for polymer= $ 10 per gallons

Salvage value = $(-5)/ gallon

Now, Using the formula for normally distributed sample,

Z = ( X - μ ) /σ

where , X---> sample mean

μ ----> population mean

σ----> standard deviations

Z -----> Z-value

from question it is clear X = 150

putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125

= - 0.8

(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.

They will run out of raw material if demands exceds this quantity or

Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%

Answer:

y = 119

30 =x

Step-by-step explanation:

61 and y are same side interior angles and they add to 180

61+y = 180

y = 180-61

y = 119

y and 6x-61 are vertical angles and they are equal

y = 6x-61

119 = 6x-61

Add 61 to each side

119 + 61 = 6x

180 = 6x

Divide each side by 6

180/6 = x

30 =x

Answer:

y = 119°

x = 30°

Step-by-step explanation:

We know that if two lines are parallel, the co - interior angles are added up to 180°°.

Accordingly,

y + 61 = 180

y = 180 - 61

y = 119°

Also, we know that, vertically opposite angles are equal to each other.

y = 6x - 61

119 = 6x - 61

Now, we have to make x the subject.

For that, first, add 61 for both sides.

119 + 61 = 6x

180 = 6x

Now, divide both sides by 6.

30° = x

The factory produced 1.404 x 10⁶ sweets in a year

Standard form is a way of writing very large numbers or very small numbers in a simpler form. It is also called scientific notation

Given that: The factory produces 270000000 sweets every

week.

To know how many sweets the factory produces in a year, we will multiply the quantity produced in a week by 52 since there are 52 weeks in a year. Thus:

Number of sweet in a year = Weekly production x 52

                                 = 270000000 x 52 = 14040000000 sweets

To express 140400000000 in standard form, we will move the position of the decimal point to the back of the first number(1) and take note of the number of steps we take to get there. The  number of steps will then be  used as the power of 10:

14040000000 = 1.404 x 10⁶

Therefore, the number of sweets produced by the factory in a year in standard form is 1.404 x 10⁶ sweets

A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.

Right-shift a function

Inside the function's argument, subtract. For instance, is essentially moved b units to the right.

You go to the right while subtracting from the parameter of the function.

Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).

also to advance a function

Outside of the function, add. For instance, is essentially shifted up units.

G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.

Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).

Therefore, choice C is right.
