The number of hours Ella worked before school was 8 hours and after school was 16 hours.

Hours worked is the number of hours actually worked, defined as the sum of all periods spent on direct and ancillary activities to produce goods and services.

Given that, Ella works two part-time jobs, before and after school, Before school, she earns $11.25/hour, and after school she earns $11.75/hour. Last week, she earned a total of $278. She works twice as many hours after school.

We are asked to find how many hours did she work at each job,

We will solve this question by using an equation,

Let the number of hours she worked before school be x and after school 2x,

Therefore, establishing the equations,

x(11.25)+2x(11.75) = 278

11.25x+23.5x = 278

34.75x = 278

x = 8

Hence, the number of hours Ella worked before school was 8 hours and after school was 16 hours.

Cost after markup = $62.05

Cost after discount = $29.18

Step-by-step explanation:

It is given that:

Cost of lizard = $36.50

Mark up = 70% = 70/100 = 0.7

Markup = 0.7 * 36.50

Markup = $25.55

Cost after markup = 36.50 + 25.55 = $62.05

Discount = 53%

Discount = 0.53 * 62.05

Discount = $32.87

Price after discount = 62.05 - 32.87 = $29.18

Therefore,

Cost after markup = $62.05

Cost after discount = $29.18

covariance is a measurement of correlation. Scaled covariance is what is referred to as correlation.

What is the connection between correlation and covariance?

Simply said, covariance is a measurement of correlation. Scaled covariance is what is referred to as correlation.

                         The linear relationship between variables is indicated by covariance, which also specifies its direction.

                          On the other hand, correlation quantifies the magnitude and direction of the linear relationship between two variables.

Formula of covariance

The covariance of x and y is 15.4. The correlation coefficient can be calculated as follows: r=Cov(x,y)/(σx∗σy) r = C o v ( x , y ) / ( σ x ∗ σ y )

Answer:

The solution is going to be the point where the two lines on a graph intersect.

Step-by-step explanation:

The solution of a system is going to be a ordered pair that satisfies all of the equations in the system. This translates to the lines intersecting on a graph since they all go through the same ordered pair.

Given:

A line passes through the points (2,-1) and (1,-5).

To find:

The equation of the line.

Solution:

If a line passes through the two points, then the equation of the line is

\(y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\)

The line passes through the points (2,-1) and (1,-5). So, the equation of the line is

\(y-(-1)=\dfrac{-5-(-1)}{1-2}(x-2)\)

\(y+1=\dfrac{-5+1}{-1}(x-2)\)

\(y+1=\dfrac{-4}{-1}(x-2)\)

\(y+1=4(x-2)\)

Using distributive property, we get

\(y+1=4(x)+4(-2)\)

\(y+1=4x-8\)

Subtract 1 from both sides.

\(y+1-1=4x-8-1\)

\(y=4x-9\)

The median weight of the players on the football team is approximately 160 lbs.

The box plot provides a visual summary of the data which shows the distribution of the weights of the players on the football team. The box plot consists of a box and two "whiskers" which represent the upper and lower quartiles of the data. The box is bounded by the upper quartile and lower quartile and the two whiskers represent the highest and lowest values in the data set, excluding any outliers. The median weight of the players is represented by the line in the middle of the box, which is approximately 160 lbs. The box plot is a useful tool for summarizing the data and provides a quick and easy way to visualize the distribution of the players' weights. The median weight of 160 lbs gives us an idea of the average weight of the players, which can be used to determine the overall strength of the team.

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

6 - 2x = 3

(You have to subtract 6 on both sides so it can cancel out)

6 - 6 - 2x = 3 - 6

-2x = -3

(Now, you divide -2 on both sides to isolate the x)

-2/(-2)x = -3/(-2)

x = 3/2

The surface area of the new box is 642 square inches, and the total cost for one box is $36.20.

To find the surface area of the new box, we first need to find the dimensions of the box. Since the volume of the original box is the same as the volume of the new box, we can set up the equation:

20 x 18 x h = 30 x 15 x 12

Solving for h, we get h = 24. Therefore, the dimensions of the new box are 20 x 18 x 24. The surface area of the new box can be found by adding up the areas of each face:

2(20 x 18) + 2(20 x 24) + 2(18 x 24) = 640 + 960 + 864 = 642 square inches.

To find the total cost for one box, we need to add up the cost of each material used. The cost of the cardboard is $0.02 per square inch, so the cost of the cardboard used for the box is:

642 x 0.02 = $12.84.

The cost of the tape is $1.75 per roll, and each roll contains 55 yards of tape (165 feet). Therefore, we need 4 rolls of tape, which cost a total of:

4 x $1.75 = $7.00.

Finally, the cost of the packing peanuts is $3.00 per cubic foot, and we need 8 cubic feet. Therefore, the cost of the packing peanuts is:

8 x $3.00 = $24.00.

Adding up these costs, we get a total cost of:

$12.84 + $7.00 + $24.00 = $36.20.

Lin should expect to sell 10 more cups of lemonade on Sunday compared to Saturday, assuming the high temperature on Sunday is 5 degrees warmer than on Saturday.



To determine the number of cups of lemonade Lin should expect to sell on Sunday compared to Saturday, we need to substitute the temperatures into the equation c = 2t - 89.

Let's assume the high temperature on Saturday is represented by t, which means the high temperature on Sunday will be t + 5 (5 degrees warmer). Substituting these values into the equation:

c(Saturday) = 2t - 89

c(Sunday) = 2(t + 5) - 89

Simplifying the equation for Sunday:

c(Sunday) = 2t + 10 - 89

c(Sunday) = 2t - 79

To find the difference in the number of cups sold, we need to subtract the equation for Saturday from the equation for Sunday:

c(Sunday) - c(Saturday) = (2t - 79) - (2t - 89)

c(Sunday) - c(Saturday) = 2t - 79 - 2t + 89

c(Sunday) - c(Saturday) = 10

Therefore, Lin should expect to sell 10 more cups of lemonade on Sunday compared to Saturday, given that the high temperature on Sunday is 5 degrees warmer than on Saturday.

The equation of the Amount paid for a trip is given by:

where x is the number of miles of the trip, while y is the total amount paid for the trip.

If we are to use a graph to solve the problem, we need a table of values first.

We shall choose 5 values for x which range from (0 to 10) in steps of 2.

The corresponding y values must be gotten by substituting these x values into the equation of the trip given above.

From the calculations done above, we have the coordinates of our graph to be:

(0, 3)

(2, 4)

(4, 5)

(6, 6)

(8, 7)

(10, 8)

Thus, we can create our table of values:

Thus, with this table of values, we can plot the graph. The plotted graph is shown below:

Therefore, the total number of miles you can travel with $20 is 34 miles

a. (2/3) ÷ (1/4) = 8/3

   √(27) ÷ √(3) = 3

b.   (4.5) × (4) = 18

   (3.6) ÷ (0.6) = 6

c.    (√2) × (√8) = 4√2

   (π) ÷ (e) = a irrational number but multiplied by an integer such as 2π/e would yield a rational number.

d.    (3+4i) × (3-4i) = 25

   log(-8) + log(2) = log(16) (using complex logarithms)

a. The first example, (2/3) ÷ (1/4) = 8/3, is an example where the inputs are not positive integers, but the result is a positive integer. This is because when we divide two fractions, we actually multiply the first fraction by the reciprocal of the second fraction. So, (2/3) ÷ (1/4) is the same as (2/3) × (4/1) = 8/3, which is a positive integer.

Therefore, For the second example, √(27) ÷ √(3) = 3, we can simplify the square root of 27 as √(3 × 9) = √3 × √9 = 3√3. Similarly, we can simplify the square root of 3 as √(3 × 1) = √3 × √1 = √3. Then, we can divide √(27) by √(3) to get 3√3 ÷ √3 = 3, which is a positive integer.

Step-by-step explanation:

If Juwad picked 30 bags of apples and only sold 26 of them for 3.45 each, then you would have to multiply the number of bags sold by the price, and you would get your answer. So in this case:

1. (#sold)* (price)= total amount of money made

2. 26*3.45= 89.70

3. And you can check by dividing 89.70(your answer) by the price of the apples

4. 89.70/3.45= 26

The given permutation (62848X) can be expressed as the product of disjoint cycles as (1 6 2 8 4) and as the product of transpositions as (1 6)(6 2)(2 8)(8 4).

To express the given permutation (62848X) as a product of disjoint cycles, we start by examining each element and its corresponding image under the permutation.

1 maps to 6.

6 maps to 2.

2 maps to 8.

8 maps to 4.

4 maps to 8 (since X represents a fixed point, meaning it remains unchanged).

Now, let's write these mappings as disjoint cycles:

(1 6 2 8 4)

The cycle notation indicates that 1 maps to 6, 6 maps to 2, 2 maps to 8, 8 maps to 4, and 4 maps back to 1.

Next, we'll express this permutation as a product of transpositions. A transposition swaps two elements.

We can achieve this by breaking down the cycle (1 6 2 8 4) into transpositions:

(1 6)(6 2)(2 8)(8 4)

Each pair of adjacent elements within the cycle forms a transposition. For example, (1 6) represents the transposition that swaps 1 and 6, (6 2) swaps 6 and 2, and so on.

Thus, the given permutation (62848X) can be expressed as the product of disjoint cycles as (1 6 2 8 4) and as the product of transpositions as (1 6)(6 2)(2 8)(8 4).

The equivalent ratio where the amount of stock is 100 mL is 80 mL

An equivalent ratio is a ratio that is equal to another ratio, but with the terms in a different order or with different values.

Since the recipe calls for 350 mL of Dashi in order to make a smaller batch using 280 mL of Dashi. Thus, we can say:

equivalent ratio = 280/350

Thus, an equivalent ratio where the amount of stock is 100 mL will be:

280/350 = x/100
