To calculate the probability of Gretchen getting a roast beef sandwich on wheat bread and popcorn in her boxed lunch, we need to know the total number of possible boxed lunch combinations and the number of boxed lunches that contain roast beef on wheat bread and popcorn.

Let's assume there are 4 different types of sandwiches available: roast beef on wheat bread, turkey on white bread, ham on rye bread, and vegetarian on whole wheat bread. Also, let's assume there are 3 different snack options available: popcorn, chips, and fruit.

If each boxed lunch contains one sandwich and one snack, then there are 4 x 3 = 12 possible boxed lunch combinations.

Out of these 12 combinations, we need to determine how many contain roast beef on wheat bread and popcorn. Let's say there are 2 boxed lunches that contain roast beef on wheat bread and popcorn.

Therefore, the probability of Gretchen randomly choosing a boxed lunch with roast beef on wheat bread and popcorn is 2/12, which simplifies to 1/6, or approximately 0.1667.

So, there is a 16.67% chance that Gretchen will get a roast beef sandwich on wheat bread and popcorn in her box.

To create a confidence range for the population standard deviation, we can use the chi-square distribution. Finding the chi-square values that correlate to 10% and 90% in the right tail of the distribution is necessary given that we have 94 samples and want an 80% confidence range.

The chi-square value for the 10th percentile is 71.47, and the chi-square value for the 90th percentile is 112.31, according to a chi-square distribution chart with 93 degrees of freedom (n-1).

The confidence interval's calculation is:

((n-1)*s2)/sqrt(X), (n-1)*s2)/sqrt(Y))

Where:

The group number is n.

The sample's standard variation is s.

X represents the bottom limit of the confidence interval's chi-square value.

Y is the chi-square value for the upper bound of the confidence interval

Substituting the values we have:

(sqrt((94-1)*4.11^2)/sqrt(112.31)) = 5.63

(sqrt((94-1)*4.11^2)/sqrt(71.47)) = 4.81

Therefore, the 80% confidence interval for the population standard deviation of the widths of all doors in this factory is (4.81, 5.63).

Answer: y = (1/4)x^2 + 1

Step-by-step explanation:

The equation of a parabola in vertex form is given by:

y = a(x-h)^2 + k

Where (h,k) is the vertex of the parabola and "a" is a coefficient that determines the shape of the parabola.

In this case, the vertex is given as (0,1), so h=0 and k=1. Also, the parabola passes through the point (8,17), which means that when x=8, y=17. We can use this information to solve for "a".

Substituting the values of h, k, x, and y in the equation, we get:

17 = a(8-0)^2 + 1

Simplifying this equation, we get:

17 - 1 = 64a

16 = 64a

a = 16/64

a = 1/4

Now that we know the value of "a", we can substitute it in the vertex form equation to get the final equation of the parabola:

y = (1/4)(x-0)^2 + 1

Simplifying this equation, we get:

y = (1/4)x^2 + 1

Therefore, the equation of the parabola in vertex form is y = (1/4)x^2 + 1.

Explanation:

We start with the general equation of a parabola in vertex form and substitute the given values of the vertex and the point that the parabola passes through. Then, we solve for the coefficient "a" by simplifying the resulting equation. Once we have the value of "a", we substitute it in the vertex form equation to obtain the final equation of the parabola.

Answer:

2/7 is the right answer

14 and 21 are both divisible by 7, their GCF, so if you divide the numerator and the denominator by 7, you get the fraction 2/7

Part A:

First, we need to find the dimensions of the print by multiplying the dimensions of the original painting by the scale factor of 3.

The width of the print is 14 inches x 3 = 42 inches

The length of the print is 24 inches x 3 = 72 inches

To convert these dimensions into feet, we need to divide by 12 (since there are 12 inches in a foot):

Width of print = 42 inches / 12 = 3.5 feet

Length of print = 72 inches / 12 = 6 feet

Therefore, the dimensions of the print are 3.5 feet by 6 feet.

Part B:

To find the area of the print, we need to multiply the width by the length:

Area of print = (3.5 feet) x (6 feet) = 21 square feet

Therefore, the area of the print is 21 square feet

Answer:

Step-by-step explanation:

1 quarter = 25 cents

1 dime = 10 cents

Let

q = the number of quarters, q>=0, q is integer

d = the number of dimes, d>=0, d is integ

30 coins totaling $4.80 = 480 cents:

q + d = 30

25q + 10d = 480

q = 12 quarters

d = 18 dimes

12 quarters and 18 dimes.

Answer:

Let x be the number of dimes in the jar.

Then the number of quarters in the jar would be 30 - x.

The total value of the dimes in the jar would be 0.10x, and the total value of the quarters would be 0.25(30 - x) = 7.50 - 0.25x.

We know that the total value of the coins is $4.80, so we can set up the equation:

0.10x + 7.50 - 0.25x = 4.80

Simplifying and solving for x, we get:

0.15x = 2.70

x = 18

Therefore, there are 18 dimes and 30 - 18 = 12 quarters in the jar.

Step-by-step explanation:

The value of y when x is equal to 10 is 60.

Value in math is the numerical representation of a given quantity. It can be a literal number, a variable, or an expression. Values are used to solve equations, calculate statistics, and determine patterns. They can be used to measure physical quantities such as length, area, volume, and force. Values are also used to measure abstract concepts such as money, probability, and time. Values help us understand and make sense of the world around us.

The value of y when x is equal to 10 can be calculated by using y = mx + c, where m is the gradient and c is the y-intercept of the line. Using the given values, we can calculate the equation of the line to be y = 5x + 10.

Therefore, when x = 10, y = 5(10) + 10 = 60.

The point (2, 2) would end up at the point (1, 1) after the transformations.

Functions can be represented in different ways, including graphs, tables, and equations. A graph of a function is a visual representation of the relation between the inputs and outputs, usually plotted on a coordinate plane. A table of values lists the inputs and corresponding outputs of a function. An equation of a function expresses the rule for calculating the output in terms of the input variable.

To sketch the graph of the new function h(x), we can start by considering the effect of each transformation on the original function f(x).

First, we have a horizontal shift of 1 unit to the left, since we are subtracting 1 from the argument of f(x). This means that the graph of f(x+1) will be shifted 1 unit to the left compared to the graph of f(x).

Next, we have a vertical stretch by a factor of 2, since we are multiplying the output of f(x+1) by 2. This means that the graph of 2f(x+1) will be twice as tall as the graph of f(x+1).

Finally, we have a vertical shift downwards by 3 units, since we are subtracting 3 from the output of 2f(x+1). This means that the graph of h(x) will be shifted 3 units downwards compared to the graph of 2f(x+1).

To find where the point (2, 2) ends up after these transformations, we can first apply the horizontal shift of 1 unit to the left, which gives us the point (1, 2). Next, we apply the vertical stretch by a factor of 2, which gives us the point (1, 4). Finally, we apply the vertical shift downwards by 3 units, which gives us the point (1, 1).

Therefore, the point (2, 2) would end up at the point (1, 1) after the transformations.

To sketch the graph of h(x), we can start with the graph of f(x) and shift it 1 unit to the left, stretch it vertically by a factor of 2, and shift it 3 units downwards. The resulting graph will have the same shape as the graph of f(x), but will be shifted and scaled as described above. The point (1, 1) will be on this graph as well.

B. On the graph of h(x), the point (2,2) would be changed into the point (2,1).

A graph is a graphical representation of data, functions, or variable connections. It is a method of displaying information that is simple to analyse and comprehend.

Graphs are widely used in a variety of disciplines, including science, economics, business, engineering, and others. They make it simpler for researchers and analysts to visualise data and identify trends or patterns, allowing them to draw conclusions and make educated choices based on the data.

A. To include the spot (-2,2), we must shift the f(x) graph two units to the right and two units up. So far, we have:

g(x) = a f(x - (-2)) + 2

g(x) = a f(x + 2) + 2

We must now determine the worth of "a." Because the point (3,4) on the f(x) graph is transferred to the point (2,2) on the g(x) graph, we have:

g(3) = a f(3 + 2) + 2 = 2

4a + 2 = 2

4a = 0

a = 0

Therefore, the function g(x) is:

g(x) = 0 f(x + 2) + 2

g(x) = 2

As a result, independent of the values of b and c, the point (-2,2) is included in the graph of g(x).

B. The function h(x) has a slope of 2 and a y-intercept of -1. We plug x=2 into h(x) to determine where the point (2,2) would end up after the transformations and get:

h(2) = 2(2+1)-3 = 1

As a result, the point (2,2) on the graph of h(x) would be changed to the point (2,1).

The transformations applied to f(x) to produce h(x) are a one-unit horizontal shift to the left (x+1), a two-unit vertical stretch (2(x+1)), and a three-unit vertical shift downwards (-3).

Find the answer

Answer: (a) John spent 2/5 of the remainder of his money on a toy. Let's first find the remainder of his money after he spent 20% on food. If he spent 20% on food, then he has 80% of his money remaining. So, if he had $x initially, he has $0.8x remaining.

John spent 2/5 of the remainder on a toy, so we can set up the equation:

(2/5)(0.8x) = 12

Simplifying, we get:

0.32x = 12

Dividing both sides by 0.32, we get:

x = 37.5

So, John initially had $37.5.

To find the percentage of his money he spent on the toy, we can use the following formula:

Percentage = (amount spent on toy / initial amount) * 100%

The amount John spent on the toy is $12, and his initial amount is $37.5, so we get:

Percentage = (12 / 37.5) * 100% = 32%

Therefore, John spent 32% of his money on the toy.

Cost price (also known as CP) is the amount of money that is required to produce or purchase a particular product or service. It includes all the expenses incurred in the production or purchase of a product, such as the cost of raw materials, labor, transportation, rent, and other overhead expenses. The cost price is an important factor in determining the profit margin of a business, as it is used to calculate the selling price of a product or service. In general, the cost price is the amount that a seller pays to acquire a product, while the selling price is the amount that a buyer pays to purchase the same product.

Let's assume that the cost price is "C".

We know that the selling price (S) is $980, and the loss percentage is 12%.

We can use the formula for calculating the cost price:

C = S / (1 - Loss%)

where Loss% is expressed as a decimal (i.e., 12% = 0.12).

Substituting the values, we have:

C = $980 / (1 - 0.12)

C = $980 / 0.88

C = $1113.64

We can expect her to pick about 70 blue marbles in the next 200 rounds.

We must divide the number of blue marbles by the total number of marbles to determine the likelihood of selecting a blue marble in a single round:

P(blue) = 14/40 = 7/20

Since the experiment has been conducted 50 times, we may anticipate that the proportion of blue marbles will eventually be around 7/20. This suggests that in the subsequent 200 rounds, Zendaya will likely choose to focus on:

70 blue marbles result from P(blue) 200 = (7/20) 200.

So, in the following 200 rounds, we can anticipate her choosing roughly 70 blue marbles.
