Each input value can have only one output value for it to be a function. In other words, there should only be one y value for each x value. The only option that satisfies this is C.

The total number of apples and oranges that they place in a bowl is given as follows:

19 fruits.

The total number of apples and oranges that they place in a bowl is obtained applying the proportions in the context of the problem.

We have that Oliver's ratio is given as follows:

Apples/Oranges = 2/3.

He placed 6 oranges, hence the number of apples is given as follows:

A/6 = 2/3

3A = 12

A = 4.

Mike's ratio is given as follows:

Apples/Oranges = 1/2.

He placed 6 oranges, hence the number of apples is given as follows:

A/6 = 1/2

2A = 6

A = 3.

Then the total number of fruits is given as follows:

6 + 4 + 6 + 3 = 19 fruits.

If total cost of a pair of shoes and jacket is $46 and cost of shoes is $8 more than cost of jacket, cost of shoes is $27 and the system of equations to determine the cost of the shoes are x - y = 8 and x + y = 46.

Let the cost of the shoes be x and the cost of the jacket be y in dollars. As cost of shoes is $8 more than the jacket,

x = y + 8

Therefore, x - y = 8    (1)

Also the total cost of the shoes and jacket is $46, therefore

x + y = 46    (2)

Adding (1) and (2) we get

2x = 54

x = 27

Therefore, cost of shoes is $27.

Answer:

$200

Step-by-step explanation:

Given :

Cost of blender + import duty = $240

Import duty = 20% of cost price

Let :

Cost of blender = x

Import duty = 20% of x = 0.2x

Therefore,

x + 0.2x = $240

1.2x = 240

x = 240 / 1.2

x = $200

Cost of blender = $200

The approximate speed of sound will be 12 miles per minute.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula is given as,

Speed = Distance/Time

Sound can travel incredibly quickly: 1 mile in about 1/12 of a minute.

Based on that, the approximate speed of sound will be

Speed = 1 / (1/12)

Speed = 1 x 12

Speed = 12 miles per minute

The approximate speed of sound will be 12 miles per minute.

After considering the deposits and withdrawals, the account balance at the end of the month is $64.23.

To calculate the account balance at the end of the month, we need to add up all the deposits and withdrawals. The negative values represent withdrawals, while the positive values represent deposits.

Starting with an initial balance of $19.96, we can calculate the final balance by adding the amounts of the deposits and subtracting the amounts of the withdrawals.

Starting balance: $19.96

Deposits: $90.95, $11.16

Withdrawals: -$28.51, -$41.34, -$88.95

Adding the deposits: $19.96 + $90.95 + $11.16 = $122.07

Subtracting the withdrawals: $122.07 - $28.51 - $41.34 - $88.95 = $64.23

Therefore, the account balance at the end of the month is $64.23.

Answer:

The solution to the system of equations be:

(x, y) = (15, -25)

Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.

Step-by-step explanation:

Let us solve and check the 4th system of equations

2x+y=5

2x – y=55

solving the system of equations

\(\begin{bmatrix}2x+y=5\\ 2x-y=55\end{bmatrix}\)

subtracting

\(2x-y=55\)

\(-\)

\(\underline{2x+y=5}\)

\(-2y=50\)

so the system of equations becomes

\(\begin{bmatrix}2x+y=5\\ -2y=50\end{bmatrix}\)

solve -2y = 50

\(-2y=50\)

Divide both sides by -2

\(\frac{-2y}{-2}=\frac{50}{-2}\)

\(y=-25\)

\(\mathrm{For\:}2x+y=5\mathrm{\:plug\:in\:}y=-25\)

\(2x-25=5\)

Add 25 to both sides

\(2x-25+25=5+25\)

Simplify

\(2x=30\)

Divide both sides by 2

\(\frac{2x}{2}=\frac{30}{2}\)

simplify

\(x=15\)

Thus, the solution to the system of equations be:

(x, y) = (15, -25)

Therefore, the fourth system of equations i.e. 2x+y=5 and 2x – y=55 has the ordered pair (15, – 25) as its solution.

Answer:

B.) The interquartile range of the data is 2

Step-by-step explanation:

Answer:

(i) False

(ii) Selecting a 5 or a spade are not independent.

Step-by-step explanation:

(i)

Independent events are those events that occur at the same time, i.e. the occurrence of one event does not effects the occurrence of the other.

If A and B are independent events then: \(P(A\cap B)=P(A)\times P(B)\)

Whereas as if two events are mutually exclusive, then the probability of them both taking place at the same time is 0.

Then for events A and B: \(P(A\cap B)=0\)

Thus, the statement is False.

(ii)

In a standard deck of 52 cards there are:

Spades = 13

Diamond = 13

Heart = 13

Clubs = 13

And each of these 13 cards are:

K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A

If a card labelled as 5 is selected then it could also be a Spade.

And if a spade is selected then the card could be labelled as 5.

So, selecting a 5 or a spade are not independent.

Answer:

To three decimal places, The process capability index is 0.167

Step-by-step explanation:

We have to find the process capability index,

Upper specification = 16.5 ounces,

Lowe specification = 15.5 ounces

Mean = 16.0 ounces

Standard Deviation = S = 1 ounce

process capability index = (upper specification - lower specification)/6S

process capability index = (16.5 - 15.5)/6(1)

= 1/6

Process capability index = 1/6 = 0.16666667

To 3 decimal places, we get,

Process capability index = 0.167

The slope is 3, the function in the table has a slope of 3.5

Step-by-step explanation:

For the equation, you can just look at the number before x for the slope. For the table, you need to form an equation. (1,5.5) (2,9) are the points that I would use. The equation is y=3.5x-2, the slope is 3.5.

The function in the table has greater rate  of change .

Given,

Line equation : y = 3x - 6

Tabular data .

Now,

In line,

y = 3x - 6

Compare it with the standard form of line

y = mx + c

Hence the slope of line is 3 .

Now the slope of table,

m = y2 - y1 /x2 - x1

m = 9 - 5.5 / 2 - 1

m = 3.5

Slope of table is 3.5 .

Thus the table data has greater slope and thus have a greater rate of change than the line .

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.

Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.

Given the following:

m∠BFC = 75°

m∠GFC = 38°

∠EFB, ∠BFC,  and ∠GFC are angles on a straight line, therefore:

m∠EFB = 180 - m∠BFC - m∠GFC

Plug in the values

m∠EFB = 180 - 75 - 38

m∠EFB = 67°

Find the measure of angle FBC:

Angles FBC and EFB are alternate interior angles, therefore:

m∠FBC = m∠EFB = 67° [alternate interior angles theorem]

m∠FBC = 67°

In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

Answer:

20/27

Step-by-step explanation:

If there are 450 grams of element and half life is 8 minutes, then it will take 28.83 minutes the element to decay to 37 grams

Half life of radio active element = 8 minutes

Initial quantity of radio active element = 450 gram

Final quantity of radio active element = 37 grams

y = a(0.5)^(t/h)

Substitute the values in the equation

37 = 450 (0.5)^(t/8)

Move 37 to left hand side of the equation

37 / 450 = 0.5^(t/8)

Convert the terms to logarithm

t/8 = \(log_{0.5}\frac{37}{450}\)

t/8 = 3.60

t = 8 × 3.60

Multiply the numbers

t = 28.83 minutes
Therefore, the it will take 28.83 minutes to decay to 37 grams
