Calculate f(4) for each function below.

Answers

Answer:

f (4) = 3(4) - 12

Step-by-step explanation:

if x = 4 just substitute the x for the 4 .

f(x) = 3x - 12

f(4) = 3 (4) - 12

f(4) = 12 - 12

and that cancels itself out.

Step-by-step explanation:

The question is attached

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

Answer options:

A. Players at school 1 typically spent more time in the weight room than players at school 2

False, as per plot boxes up to 75% of players from school 1 spend up to 10 hours but up to 75% of players from school 2 spend up to 12 hours in the weight room

B. The middle half of the data for school 1 has more variability than the middle half of the data for school 2

True. 4 hours variation for school 1 vs 3 hours variation for school 2

C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal

True as it is 8 hours for school 1 and 9 hours for school 2

D. The total number of hours spent in the weight room for players at school 2 is greater than the total number of hours for players at school 1

True. Taking into account a sum of 5 numbers of the plot box. For School 1 it is: (3+4+8+10+16)= 41 and for school 2 it is: (3+6+9+12+14) = 44. Totals will have similar ratio.

The altitude of an airplane is represented in the graph below. A graph with time (minutes) on the x-axis and altitude (feet) on the y-axis. Points are at (0, 0), (20, 12,000), (40, 24,000), (60, 36,000), (80, 36,000), (100, 36,000), (120, 36,000), (130, 36,000), (140, 24,000), (160, 12,000), and (180, 0). Is the airplane’s altitude a function of time? Yes, because any input of time results in only one output of altitude. Yes, because the airplane increases and decreases in altitude at the same rate. No, because each output of altitude has more than one input of time. No, because the altitude is constant between 60 minutes and 130 minutes.

The sum of twice a number and 7 is -19

Answers

Answer:

The number will be -13

Step-by-step explanation:

Let the no. be x

Its twice will be = 2x

According to the question ,

[tex]2x + 7 = -19\\=> 2x = -19 - 7 = -26\\=> x = \frac{- 26}{2} = - 13[/tex]

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of the number is -13.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The sum of twice a number and 7 is -19.

Let the number be M.

Now,

2M + 7 = -19

We will solve for M.

2M + 7 = -19

Subtract 7 on both sides.

2M + 7 - 7 = - 19 - 7

2M = -19 - 7

2M = -26

Divide both sides by 2.

M = -26/2

M = -13

We can cross-check.

2M + 7 = -19

2 (-13) + 7 = -19

-26 + 7 = -19

-19 = -19

Proved

Thus.,

The value of the number is -13.

The data set gives the number of bottles filled by each of the workers in a bottling plant in one day. {36, 18, 16, 28, 68, 35, 37, 66, 38, 40, 41, 44, 72, 29}

Answers

Answer:

The best measure of center is median = 37.50.

Step-by-step explanation:

The complete question is:

The data set gives the number of bottles filled by each of the workers in a bottling plant in one day.

{36, 18, 16, 28, 68, 35, 37, 66, 38, 40, 41, 44, 72, 29}

The best measure of center for this data set is the , and its value expressed up to one decimal place is?

Solution:

The three measures of center are:

MeanMedianMode

The mean is the average value of the data set and uses all the values of the data set.

The median is the middle value of the data set.

Mode is the value of the data st with the highest frequency or number of occurrence.

Compute the mean, median and mode of the data set provided as follows:

[tex]\text{Mean}=\frac{1}{n}\sum X=\frac{1}{14}\times [36+18+....+72+29]=40.57[/tex]

So, the mean is 40.57.

The data set in ascending order is:

{16 , 18 , 28 , 29 , 35 , 36 , 37 , 38 , 40 , 41 , 44 , 66 , 68 , 72}

There are 14 values in the data set. That is an even data set.

The median for an even data set is the average of the middle two values.

The middle two values are: 37 , 38

Average of {37 , 38} = [tex]\frac{37+38}{2}=37.50[/tex]

So, the median is 37.50.

None of the values are repeating itself. Thus, the data does not have a mode.

For the provided data:

Mean > Median

Implying that the data set is right-skewed.

For a skewed distribution or data set the median is the measure of center.

Thus, the best measure of center is median = 37.50.

What is the image of (9,0) after a dilation by a scale factor of 2 centered at the origin?

Answers

Answer:

(-18,0)

Step-by-step explanation:

Dilation involves changing the size of a point.

The image of (9,0) after a dilation by a scale factor of 2 centered at the origin is (18,0)

The point (P) is given as:

[tex]P = (9,0)[/tex]

The scale factor (k) is given as:

[tex]k = 2[/tex]

The image after a dilation centered at the origin is the product of the coordinates of the point and the scale factor.

So, we have:

[tex]P' = P \times k[/tex]

This gives

[tex]P' = (9,0) \times 2[/tex]

Expand

[tex]P' = (9\times 2,0\times 2)[/tex]

Evaluate the products

[tex]P' = (18,0)[/tex]

Hence, the image of (9,0) is (18,0)

The Frog, one day intent on mischief, bound the foot of the Mouse tightly to his own. Thus joined together, the Frog first of all led his friend the Mouse to the meadow where they were accustomed to find their food. After this, he gradually led him towards the pool in which he lived, until reaching the very brink, he suddenly jumped in, dragging the Mouse with him. The Frog enjoyed the water amazingly, and swam croaking about, as if he had done a good deed. The unhappy Mouse was soon suffocated by the water, and his dead body floated about on the surface, tied to the foot of the Frog. A Hawk observed it, and, pouncing upon it with his talons, carried it aloft. The Frog, being still fastened to the leg of the Mouse, was also carried off a prisoner, and was eaten by the Hawk.1.
