Answer: 1.5 cakes per hour

Answers:

For each row, you're adding the values of 'a' and 'b'. The first row has 1+2 = 3.

When adding two negatives, add the positive versions of each number, then make the result negative. So -1 + (-2) can be thought of as 1+2 = 3, then you make everything negative.

When adding a negative to a positive, you'll subtract the positive version of each number. The final result is positive if the larger absolute value is positive, or otherwise it's negative. We have -4+1 that can be thought of as 4-1 = 3, but since the '4' is larger and it is negative, this means -4+1 = -3.

Step-by-step explanation:

In this problem we are expected to sum up the number of lines recorded during all court sessions for the day.

Also we know that the court report, reported for two (2) court session for that day.

Hence all the number of line is going to be from the 2 court sessions she reported

in the first court session we wrote 47 lines

in the second court session we reported 33 line

the total lines in all is 47+33= 80 lines

The total line recorded for the day is 80 lines

Answer:

Domain: (-5, 6]

Range: [-3, 6]

Step-by-step explanation:

Domain is all x-values that can be inputted into function f(x).

Range is all the y-values outputted by function f(x) when we plug in x.

We see that our x-values span from -5 to 6. Since -5 is a open dot, we cannot input -5. Therefore, we have:

Domain: (-5, 6]

Parenthesis on -5 shows that it is not included and bracket on 6 shows it is included.

We see that our y-values span from -3 to 6. Since both points are closed dots, we can include both. Therefore, we have:

Range: [-3, 6]

Brackets on both numbers signify that both values are included in the graph.

Answer:

D. 16

Step-by-step explanation:

[tex] GH^2 = GF \times GE[/tex]

[tex] 12^2 = 9 \times (9+x - 2)[/tex]

[tex] 144= 9 \times (7+x)[/tex]

[tex] \frac{144}{9}= (7+x)[/tex]

[tex] 16= 7+x [/tex]

[tex] 16-7=x [/tex]

[tex] 9=x [/tex]

GE = 9 + x - 2 = 9 + 9 - 2 = 18 - 2

GE = 16

Answer:

D.16

Step-by-step explanation:

GE × GF = GH^2

9 × (9 + x - 2 ) = 12^2

63 + 9x = 144

9x = 81

x = 9

so, GE = 9 + x - 2

= 7 + 9

Disclaimer: The given question was incomplete, with the data missing. The complete question can be seen in the picture attached.

Analyzing and interpreting the given data, we can say that Amy took 18 1/4 minutes in total to run her slowest and fastest mile combined.

The process of attributing meaning to the acquired data and deciding the conclusions, relevance, and consequences of the results is known as data analysis and interpretation.

We are given a data set, representing the time taken by Amy to run each mile while running 8 miles, nearest to 1/4th of a minute.

We are asked to find how long did it take Amy to run her slowest and fastest mile combined.

Analyzing the data, we can say that her slowest mile will be the one for which she took the maximum time, that is, 9 2/4 minutes. Whereas her fastest mile will be the one with the minimum time, that is, 8 3/4 minutes.

We are asked to tell the combined time for her slowest and the fastest mile, so we add times for both, to get

Combined time = 9 2/4 + 8 3/4

or, Combined time = 38/4 + 35/4

or, Combined time = 73/4

or, Combined time = 18 1/4.

∴ Analyzing and interpreting the given data, we can say that Amy took 18 1/4 minutes in total to run her slowest and fastest mile combined.

Answer:

For a given length l and width w, the new perimeter is....

2(l + w) + 8

Step-by-step explanation:

Currently, the rectangle's perimeter is 2(l + w). You knew that.

Now, the question asked you to change l into l + 7, and w into w - 3. Substitute them, so we get

Perimeter New = 2(l + 7 w - 3) = 2 (l + w + 4)

Then, I chose to "pull out" + 4, so I multiply it with the 2. Hence, we get

Perimeter New = 2 (l + w) + 8

Answer:

we know that,

y-y1=m(x-x1)

or, y-1=-3(x-5)

or, y-1=15-3x

or 3x+y-16=0 is the required equation

The graph of the line with slope -3 passing through the point (5,1) is attached.

The equation of the line in the slope-intercept form is y = -3x + 16.

The equation of the line in the standard form is 3x + y = 16.

The equation of a line is the representation of a line on a coordinate plane (x-y plane), which shows the relation between x and y, for every point on the particular line.

The standard form of a line is ax + by = c, where x and y are variables and a, b, and c are constants.

The slope-intercept form of a line is y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept of the line.

The equation of a line passing through the point (x₁, y₁), having a slope m, is represented by the one-point formula: y - y₁ = m(x - x₁).

We are asked to graph a line with a slope = -3, passing through the point (5, 1).

We use the one-point formula to determine the equation of this line, with slope m = -3, (x₁, y₁) = (5, 1).

Substituting these values in the equation y - y₁ = m(x - x₁), we get

y - 1 = -3(x - 5)

or, y = -3x + 15 + 1

or, y = -3x + 16.

or, 3x + y = 16

The equation of the line in the slope-intercept form is y = -3x + 16.

The equation of the line in the standard form is 3x + y = 16.

To graph this line we plot the points (5, 1) (as it is given that it passes through this point) and (0, 16) (as the y-intercept is at 16, so the line passes through the point (0, 16)). We join these points by a line and extend this line on both sides to get the required line.

Step-by-step explanation:

If you look at the objects thrown as garbage, it's a two- or three-dimensional item that takes up space and also has mass and this is a solid waste.

And the landfill that dumps such garbage is also three-dimensional.

Hence, the volume module, if the object inside is a solid, either would be

Answer:

Null hypothesis : top speed = height

Alternative hypothesis : top speed ≠ height

Dependent variable : speed

Independent variable : Height

Step-by-step explanation: The experiment aims to determine the relationship between the height of ramp and the top speed reached by her skateboard.

The Null hypothesis: top speed = height

while the alternative hypothesis will negate the Null.

Alternative hypothesis : top speed ≠ height

The dependent variable in the experiment will be her top speed, because it is the variable we want to evaluate. We want to determine if thwre will be a change in the top speed of the skateboard if there is change in another variable 'height' of ramp. The variable which might cause a change in value of our dependent variable is called the independent or predictor variable, which in this case is the height variable.

Answer:

Hector's kite is 61.84 feet from the ground.

Step-by-step explanation:

The angle of elevation of the kite is 42°15’30” when converted to decimals, it is [tex]42.258333^{0}[/tex] ≅ [tex]42.26^{0}[/tex]

Let the height of the kite to the horizontal of angle of elevation be represented as x. Applying the trigonometric function to the sketch of Hector's kite,

Sin θ = [tex]\frac{opposite}{hypotenus}[/tex]

Sin [tex]42.26^{0}[/tex] = [tex]\frac{x}{86}[/tex]

⇒ x = 86 x Sin [tex]42.26^{0}[/tex]

      = 86 x 0.6725

     = 57.835

x ≅ 57.84 feet

The height of Hector's kite from the ground = x + 4

                                    = 57.84 + 4

                                   = 61.84 feet

Answer:

Below.

Step-by-step explanation:

A measure of variation is an estimate of the spread of the numbers.

For example the set of numbers 1 2 3 19 78 has a greater measure of variation than the set 1 2 3 5 9.

The interquartile range and the mean absolute deviation are measures of variation.

3 6 8 15 21 22 23

The median of the data is the middle number 15..

The lower quartile is 6 and the higher quartile is  22

The interquartile range is 22 - 6 = 16.

The mean absolute deviation (M.A.D.) is calculated as follows:

Mean = (3+6+8+15+21+22+23) / 7 = 98/7

= 14.

List the absolute differences from the mean

14 - 3 = 11

14-6 = 8

15-14 = 1

21-14= 7

22-14 = 8

23-14 = 9   ( all these have to be positive)

The sum of the differences is 11+8+1+7+8+9 = 44

So the MAD = 44/7 = 6.3 to nearest tenth.

Answer:

2. Kayla's opportunity cost to go to the movie is $9.50

4. Tara's total cost of attending the movie is $50.5

Step-by-step explanation:

Complete question below:

Tara earns $8.50 an hour (after taxes) at the pizza place. She is scheduled to work four hours this afternoon. However, her friend Kayla called and asked her if she wants to go to the movie. A ticket to the movie costs $9.50. In addition, she always spends about $7 on snacks.

Which of the following statement are true? Select all that apply.

1. Tara's opportunity cost if she goes to work instead of the movie is $34.

2. Kayla's opportunity cost to go to the movie is $9.50.

3. There is no opportunity cost for Tara to go to the movie.

4. Tara's total cost of attending the movie is $50.5

5. Tara's opportunity cost if she goes to the movie instead of working is $34

Solution

Tara earns $8.50 per hour

She is scheduled to work for 4 hours

Total earnings=$8.50 × 4

=$34

Tara's opportunity cost of attending the movie instead of working is $34

Since, a ticket cost $9.50

And she always spend about $7 on snacks

Tara's total cost of going to the movies = opportunity cost of attending the movie + cost of tickets + cost of snacks

=$34 + $9.50 + $7

=$50.5

Opportunity cost refers to the cost of satisfying a want at the expense of another want. It can also be called REAL COST or TRUE COST.

Therefore,

2. Kayla's opportunity cost to go to the movie is $9.50

4. Tara's total cost of attending the movie is $50.5
