During the spring and summer, a concession stand at a community Little League baseball game field sells soft drinks and other refreshments. To prepare for the season, the concession owner refers to the previous year's files, in which he had recorded the daily soft drinks sales (in gallons) and the average daily temperature (in degrees Fahrenheit). Using the coordinates of the two points (84,80) and (74,65), determine the slope of the line of best fit.

Answers

Answer 1

Answer:

  1.5

Step-by-step explanation:

The slope is given by ...

  (change in dependent variable)/(change in independent variable)

  = (65 -80)/(74-84) = -15/-10 = 1.5

The slope of the line of best fit is 1.5.

Answer 2

Answer:

The slope of the line of best fit is 1.5 degrees Fahrenheit per gallon.

Step-by-step explanation:

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The given two points are (84,80) and (74,65).

The slope of the line of best fit is

[tex]m=\frac{65-80}{74-84}[/tex]

[tex]m=\frac{-15}{-10}[/tex]

[tex]m=1.5[/tex]

Therefore the slope of the line of best fit is 1.5 degrees Fahrenheit per gallon.

Is the work shown in the simplification below correct? explain. csc(t) sec(t) = 1 cos(t) ÷ 1 sin(t) = 1 cos(t) • sin(t) 1 = 1 sin(t) = tan(t)?

Answers

Answer:

The work shown in the simplification below is incorrect.

Step-by-step explanation:

To start; we have to know  what csc(t) and sec(t) is.

csc(t) = 1/sin(t)      and    sec(t)= 1/cos(t)

So in the above simplification it was all mixed up, csc(t) was substituted with 1/cos(t) instead of 1/sin(t) and sec(t) was substituted with 1/sin(t) instead of 1/cos(t).

So, we are going to solve it the right way;

csc(t) sec(t) = [tex]\frac{1}{sin(t)}[/tex]   ÷   [tex]\frac{1}{cos(t)}[/tex]

                   =  [tex]\frac{1}{sin(t)}[/tex]   ×   [tex]\frac{cos(t)}{1}[/tex]

                    =[tex]\frac{cos(t)}{sin(t)}[/tex]

                    = cot(t)

Therefore csc(t) sec(t) = cot(t)   and not tan(t).

Final answer:

The simplification shown is not correct because the steps used are incorrect and the resulting expression is not equivalent to the original. The correct simplification is csc(t) sec(t) = 1/(sin(t) * cos(t)).

Explanation:

The simplification shown is not correct. Let's break it down step by step:

csc(t) sec(t) = 1/sin(t) * 1/cos(t) = (1/cos(t)) * (1/sin(t)).Using the commutative property of multiplication, we can switch the order: (1/sin(t)) * (1/cos(t)) = (1/cos(t)) * (1/sin(t)).Multiplying the fractions together, we get 1/(cos(t) * sin(t)).However, 1/(cos(t) * sin(t)) is not equal to 1/sin(t). Therefore, the simplification is incorrect.

To simplify the expression correctly, we can use the reciprocal identities: csc(t) = 1/sin(t) and sec(t) = 1/cos(t). When multiplying these together, we get:

csc(t) * sec(t) = (1/sin(t)) * (1/cos(t)) = 1/(sin(t) * cos(t)).

So, the correct simplification is csc(t) sec(t) = 1/(sin(t) * cos(t)).

Chuck is making a salad to go with his soup. The recipe calls for 2.1 cups of lettuce per person and 0.56 ounces of salad dressing per cup of lettuce. If 11 dinner guests want salad, how many ounces of dressing will be necessary? Round the answer to the nearest whole ounce. 1 ounce 2 ounces 6 ounces 13 ounces

Answers

Hello!

The answer is:

There will be necessary 13 ounces of salad dressing.

Why?

Since we already know that there will be needed 0.56 ounces of salad dressing per cup, and the recipe calls 2.1 cups of lettuce per person, we need to calculate the total ounces of salad dressing per each person, and then, calculate it for 11 persons.

So, calculating we have:

[tex]SaladDressingPerPerson=Cups*SaladDressing=2.1*0.56oz\\\\SaladDressingPerPerson=1.176oz[/tex]

Therefore, we know that there will be needed 1.176 ounces of salad dressing per person.

Then, calculating the ounces of dressing for 11 dinner guests, we have:

[tex]TotalOunces=SaladDressingPerPerson*NumberOfPersons\\\\TotalOunces=1.176ounces*11=12.94ounces=13ounces[/tex]

Hence, we have that there will be necessary 13 ounces of salad dressing.

Answers

Answer:

D

Step-by-step explanation:

y = -0.2 x²

This has a negative sign, as opposed to y = x², so it will point in the opposite direction.

The leading coefficient (0.2) is less than 1.  This means the parabola is shrunk vertically, or stretched horizontally.  So the parabola is wider than y = x².

Final answer:

The graph of y = -0.2x² is wider than and opens in the opposite direction of the graph of y = x² due to the negative and smaller in absolute value coefficient.

Explanation:

The comparison of the graphs of y = -0.2x² and y = x² is affected by the coefficients of the x² term. In the case of y = x², the coefficient is positive (1), implying the graph is a parabola that opens upwards. On the other hand, the negative coefficient (-0.2) in y = -0.2x² indicates the graph is also a parabola but opens downwards.

Furthermore, the absolute value of the coefficient affects the width of the parabola. A coefficient smaller in absolute value than 1, such as -0.2, makes the parabola wider than the parabola of y = x², which is the standard case. Therefore, the graph of y = -0.2x² is wider than and opens in the opposite direction of the graph of y = x².

Question 24 (1 point)

Leanne has a gas card that has $150 on it. She spends $25 a week on gas. Write a recursive

rule that represents the amount of money she has on her gas card after the first week.

Answers

Answer:

[tex]A_{(x)}[/tex] = 150 - 25x

Step-by-step explanation:

Let Leanne uses gas for x weeks.

Since expenditure on gas for one week = $25.00

Therefore, Leanne will spend on gas for x weeks = $25x

It is given in the question that she has total amount = $150.00

So the amount Leanne is left with after x weeks = 150 - 25x

If we represent amount left, by [tex]A_{(x)}[/tex]

so the recursive formula will be

[tex]A_{(x)}[/tex] = 150 - 25x

Now for x = 1 week

[tex]A_{(1)}[/tex] = 150 - 25 = $125

Therefore, Leanne will have $125 in her gas card after the first week.

Select the values for p, q, and r that will make the following equation true.
px2 + qx + r = (3x + 1)(x - 5)
A. p = 3
B. p = 4
C. q = -16
D. 9 = -14
E. r = -5
F. r = -4

Answers

Answer:

P= 3

Q= -14

R= -5

Step-by-step explanation:

Just solve the equation on the right side, you'll get:

=3x^2 -15x +x -5

=3x^2 -14x -5

Now compare it to the equation on the left side,

The coefficient of x^2 on the left is "p", on the right that we just solved is 3.

Same for "q" which is the coefficient on the left, on the right it's -14.

And for "r" it's -5 from the equation on the right.

Final answer:

Expanding the right side of the equation (3x + 1)(x - 5), we get 3x^2 - 14x - 5. Matching coefficients, we find that p = 3, q = -14, and r = -5.

Explanation:

To solve for the values of p, q, and r that will make the equation px2 + qx + r = (3x + 1)(x - 5) true, we need to expand the right side and then compare coefficients. Expanding the right side, we have:

3x2 - 15x + x - 5

This simplifies to:

3x2 - 14x - 5

Now, we match the coefficients from the expanded form to the left side of the equation:

p must match the coefficient of x2, which is 3.

q must match the coefficient of x, which is -14.

r must match the constant term, which is -5.

Therefore, the correct values are:

A. p = 3

D. q = -14

E. r = -5

Avery and Caden have saved $27,000 towards a down payment on a house. They want to keep some of the money in a bank account that pays 2.4% annual interest and the rest in a stock fund that pays 7.2% annual interest. How much should they put into each account so that they earn 6% interest per year

Answers

Answer:

They should put $6750 in the bank account and $20,250 in the stock fund.

Step-by-step explanation:

Consider the provided information that Avery and Caden have saved $27000.

Let x is the money deposit in the bank and y is the money deposit in stock fund.

Therefore,

x + y = 27000

x  = 27000 - y

The bank account will pay 2.4% annual interest.

[tex]\frac{2.4}{100}x+x=1.024x[/tex]

Stock fund pays 7.2% annual interest.

[tex]\frac{7.2}{100}y+y=1.072y[/tex]

Therefore,

1.024 x + 1.072 y = 1.06 × 27000

Substitute the x  = 27000 - y in above equation.

1.024 (27000 − y) + 1.072 y = 1.06 × 27000

27648 − 1.024 y + 1.072 y = 28620

0.048 y = 28620-27648

0.048 y = 972

y = 20250

Now, substitute the y = 20250 in x  = 27000 - y.

x = 27000 − 20250

x = 6750

Hence, they should put $6750 in the bank account and $20,250 in the stock fund.

26 = (2w - 5) + (2w - 5) + w + w

Now you must solve for w

26 = 2w - 5 + 2w - 5 + w + w

Combine like terms

26 = 2w - 5 + 2w - 5 + w + w

26 = 6w - 5 - 5

26 = 6w - 10

Bring -10 to the other side by adding it to both sides

26 + 10 = 6w + (-10 + 10)

36 = 6w + 0

36 = 6w

Isolate w by dividing 6 to both sides

36/6 = 6w/6

6 = w

Width is 6 cm

To find length plug 6 in for w in the equation 2w - 5

2(6) - 5

12 - 5

7

Length is 7 cm

Hope this helped!

Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches , which best describes the values of x and y

Answers

Answer:

X would be the unit of measure (weight) and Y would be the ammount. In a equation that would be, 2x = y.

Answer:

The values of both x and y will be greater than or equal to zero.

Step-by-step explanation:

We are given that

Cost of 1 pound of peaches=$2

If x represents the number of pounds of peaches bought.

Total cost of the peaches represented by y.

We have to find the the values of x and y which describes the best.

To find the total cost of peaches we will multiply the cost of one pound with total number of pounds of peaches.

If cost of  1 pound of peaches=$2

Cost of x pounds of peaches=[tex]2\times x=2x[/tex]

Therefore, the total cost of x pounds of peaches, [tex]y=2x[/tex]

Weight of a thing  is always greater than 0 or equal to .

The total cost of a thing   is always greater than or equal to zero.

Therefore,the values of both x and y will be greater than or equal to zero.

Please explain how to get the answer, with step by step explination. I would like to know, so I can do it by my self in the future.

Answer:

(-8, 135°)

Step-by-step explanation:

(8, -45°) has magnitude 8 and direction -45°.

If we add 180° to the direction and change the sign of the magnitude, we'll have the same point.

(-8, -45° + 180°) = (-8, 135°)

SAFF (Students against Fatty Food) is a group of students who are protesting the food in high school cafeterias. At a recent rally, the students covered the first 40 yards by 40 yards of the football field. There were 24 students in each 8 feet by 8 feet square. What steps would you take to determine how many students were present at the rally?
Convert yards to feet, then divide by feet square and multiply by the number of students.


Multiply the feet by the number of students.


Multiply yards by feet and divide by the number of students


Multiply the number of students by the yards of the football field.

Answers

Answer:

The total area covered by students is 40 yd x 40 yd = 1600 yd^2

 

24 students covered 8 ft x 8ft  or (8 ft x 1 yd/3 ft)^2 = [(8/3) yard]^2 = (64/9) yd^2

 

Therefore, you need the amount of students per yard or 24 students/(64/9) yd^2

 

and multiply (students/yd^2)  x  (area covered by students) = number of total students present

 

Therefore:   number of students present = 24 students/(64/9) yd^2 x 1600 yd^2 = 5400 students
