The relationship between the given data can be described in

terms of functions.

Correct response:

1. 60 °F

2. Day 2, Day 4, and Day 6

3. The high temperature is a function of the day

4. The day is not a function of the high temperature

The relationship between the Day and the high temperature

is given by the information in the table, and the definition from

the definition of functions.

The probable table in the question as obtained from a similar question posted online is presented as follows;

[tex]\begin{tabular}{|l|c|c|c|c|c|c|c|c|c|c|}Day&1&2&3&4&5&6&7&8&9&10\\Temperature (degrees F)&60&61&63&61&62&61&60&65&67&63\end{array}\right][/tex]

Please find attached the graph of the above table created with MS Excel

The probable questions are;

1. The high temperature on Day 7

Solution;

2. The days on which the high temperature was 61 °F

Solution;

From the table, the days on which the high temperature was 61 °F are;

3. A function is a relationship in which an input has exactly

one output, and a variable y is said to be a function of a

variable x if each value of x gives one value of y.

Where x = The day, and y = The high temperature, we have;

Each day has exactly one output of high temperature,

Each value of x, the day, gives one value of y, the high

temperature.

Therefore;

4. When the input variable x is the high temperature, and the

output variable, y is the day, we have;

At high temperatures, x, of 61° F, the days y are Day 2, Day 4,

and Day 6.

Therefore;

Some values of high temperature, x, have more than one value of the Days y.

Therefore;

Answer:

  6×5×4×0 = 0

Step-by-step explanation:

In order for a product to be zero, one (or more) of the factors must be zero. You can pick any numbers you like for the factors, but one of them must evaluate to zero.

  0 = 0·3·2·1

  0 = -85·(3 -2 -1)

Answer: (5,5)

Step by step explanation:

We have the two equations

-7x + y = -30 and y = 2x - 5

one of the equations "define" y therefore we can plug the value of y into the other equation and solve for x

-7x + y = -30

plug in y = 2x - 5

-7x + 2x - 5 = -30

combine like terms

-5x - 5 = -30

add 5 to both sides

-5x = -25

divide both sides by -5

-5x/-5 = x and -25/-5 = 5

we're left with x = 5

we now plug in the value of x into one of the equations and solve for y

2x - 5 = y

x = 5

2(5) - 5 = y

multiply 2 and 5

10 - 5 = y

subtract

y = 5

the solution is (5,5)

Step-by-step explanation:

The value of the expression for the given value of z is 16

From the question, we are to evaluate the given expression for the given value of unknown

The given expression is 6z - 2z

We are to evaluate this expression for z = 4. To do this, we will put in the value of 4 for z in the expression and simplify.

That is,

6z - 2z becomes

Answer: A.   165

=================================================

Explanation:

Step one is to convert the mixed number to an improper fraction

[tex]a \frac{b}{c} = \frac{a*b+c}{c}\\\\82 \frac{2}{3} = \frac{82*3+2}{3}\\\\82 \frac{2}{3} = \frac{248}{3}\\\\[/tex]

We'll divide that result by 1/2

[tex]\frac{248}{3} \div \frac{1}{2}\\\\\frac{248}{3} \times \frac{2}{1}\\\\\frac{248\times 2}{3\times 1}\\\\\frac{496}{3}\\\\[/tex]

Dividing by 1/2 is the same as multiplying by 2.

Then use your calculator to find that

[tex]\frac{496}{3} \approx 165.333\\\\[/tex]

Answer:

  A) 12 cm

  B) 520 cm² (just sides); 720 cm² (sides and base)

Step-by-step explanation:

The volume of a triangular prism is given by the formula ...

  V = 1/2LWH . . . L = length, W = width, H = height

Filling in the given dimensions, we can find the height.

  1200 cm³ = 1/2(20 cm)(10 cm)H

  1200 cm³/(100 cm²) = H = 12 cm . . . . divide by the coefficient of H

The height of the box is 12 cm.

__

Only the two rectangular faces with dimensions 13 cm by 20 cm are described in this problem statement as "sides." The area of each of those two faces is ...

  A = LW

  A = (20 cm)(13 cm) = 260 cm²

So, the area of the two sides is ...

  2 × 260 cm² = 520 cm² . . . . area of sides

__

If we also describe the base as a side of the box, its area is ...

  A = LW = (20 cm)(10 cm) = 200 cm²

Added to the area of the other two sides, the total "side" area is 720 cm².

Answer:

a = 2√11

Explanation:

Using Pythagoras theorem:

           a² + b² = c²

          a² + 10² = 12²

          a² = 144 - 100

          a² = 44

          a = √44

          a = √2*2*11

          a = 2√11

Answer:

a = 2√11

Answer:

The age of the person who walked in the room is 44.

Step-by-step explanation:

The original mean age is 38 which means the total ages combined divided by the 5 people.

5 people x 38 (the mean age) = x

x = Total ages combined

x = 190 years old

Then another person came in, now totaling 6 people, and the mean age changed to 39 years old, an increase.

6 people x 39 (the new mean age) = y

y = Total ages combined

y = 234 years old

So, we are trying to figure out the age of the new person who came in. We have to subtract the new total age (y) by the original total age (x).

y - x = Age of new person in room

234 years old - 190 years old =

44 years old

pls mark brainliest

Step-by-step explanation:

let the number be x

so,

25% of x = 16

→ 25/100 × x = 16

→ x = 16 × 100/25

→ x = 1600/25 → 64

therefore,

25% of 64 is 16.

Hope this answer helps you dear!

16 is 25% of 64.

Percentage is the fraction of an amount that is usually expressed as a number out of hundred. Percentages are a measure of frequency.

In order to determine the number, divide 16 by 25%

16 / 25%

16 / 0.25 = 64

Answer:

[tex]x[/tex] = 24.57 to the nearest hundredth

Step-by-step explanation:

The three sides of a right-angled triangle have specific names:

The 3 trigonometric ratios are:

[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]

For the given triangle we are given the angle, the hypotenuse, and need to find the side that is ADJACENT to the angle.

Therefore, we would use the trig ratio:  [tex]cos(\theta)=\frac{A}{H}[/tex]

Substituting the values from the triangle:  [tex]cos(35)=\frac{x}{30}[/tex]

Multiply both sides by 30:  [tex]30cos(35)=x[/tex]

Therefore, [tex]x=24.57456133...[/tex]

So [tex]x[/tex] = 24.57 to the nearest hundredth

Answer:

r=6

Step-by-step explanation:

(r-(-3))/(2-(-1)) = (r+3)/3

r+3/3 = 3/1

cross-multiply:

r+3 = 9

r = 6

Check:

6-(-3)/2-(-1) should equal 3

9/3 = 3

checks out correctly

Answer:

r = 6

Step-by-step explanation:

Formula

m = (y2 - y1)/(x2 - x1)

Givens

x1 = - 1

x2 = 2

y1 = - 3

y2 = r

m = 3

Solution

3 = (r - -3) / (2 - - 1)         Combine

3 = (r + 3) / 3                 Multiply both sides by 3

9 = r + 3                       Subtract 3 from both sides

6 = r + 3 - 3

6 = r

Answer:

The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100

Step-by-step explanation:

Let

x ------> the amount of money that should be invested at the rate of 12%

3,000-x -----> the amount money that should be invested at the rate of 10%

we know that

The sum of the interest on each of the accounts must be equal to the total interest.

Solve for x

therefore

The amount of money that should be invested at the rate of 12% is $900 and the amount of money that should be invested at the rate of 10% is $2,100

Answer:

Step-by-step explanation:

Answer: Mary makes $374 for 17 hours of work.

Step-by-step explanation:

Begin by getting the hourly pay. Do this by dividing the amount they made by how many hours they worked:

$176 / 8 hours = $22 / hour

Now you know the hourly rate, multiply it by how many hours she would've worked:

$22 * 17 hours = $374 for 17 hours of work.

take the second equation and plug it into the first one after you set it equal to x.

so y+4=x then plug it into the first equation.

y=y+4-4

then 4-4=0

so your answer would be y=y which would make it be no solution

3x = x - 4

x = -2

Since y = 3x, then y = 3(-2) = -6. It also satisfies the second equation

how do you solve

y=3x

y=x-4

using substitution

----------

3x = x-4

2x = -4

x = -2

--------

y = -6
