Kai took five tests this semester. His scores are listed below.
92, 88, 90, 96, 84
What is the mean absolute deviation of Kai's test scores?

Answers

Answer 1

Answer: 16

Step-by-step explanation:

Find the mean absolute deviation of the data:

X : 92, 88, 90, 96, 84

Find the mean(m) of the data:

m = Σ(X) / n

n = number of samples

(92 + 88 + 90 + 96 + 84) / 5

m = 450 / 5

m = 90

Absolute Deviation of each value of the mean:

|x - m| :

|92 - 90| = 2

|88 - 90| = 2

|90 - 90| = 0

|96 - 90| = 6

|84 - 90| = 6

Σ|x - m| = 2 + 2 + 0 + 6 + 6 = 16

A friend asks to borrow $250 for 100 days and agrees to pay 36.5% annual simple interest. How much interest will you earn? Assume that one year has 365 days

Answers

Answer:

$25

Step-by-step explanation:

We express the interest rate r in decimal form, so we have r=36.5%=36.5100=0.365. We express the time t in years, so we have t=100365. The principal is P=250, so the interest is I=Prt=(250)(0.365)(100365)=$25. The interest earned is $25.

Find the slope of the line that passes between the points (4, 3/8) and (6, 7/8)

Answers

Answer:

1/4

Step-by-step explanation:

We have two points, so we can use the slope formula

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

    = ( 7/8 - 3/8 ) / ( 6-4)

     = ( 4/8) /2

     = 1/2 / 2

13 - 2n = 19

Answers

Answer:

n=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

13−2n=19

13+−2n=19

−2n+13=19

Step 2: Subtract 13 from both sides.

−2n+13−13=19−13

−2n=6

Step 3: Divide both sides by -2.

−2n/−2=6/−2

[tex]13 - 2n = 19[/tex]

Subtract sides -13

[tex]13 - 13 - 2n = 19 - 13[/tex]

[tex] - 2n = 6[/tex]

Divided sides by -2

[tex] \frac{ - 2}{ - 2}n = \frac{ 6}{ - 2} \\ [/tex]

Data were collected on two variables, x and y, to create a model to predict y from x. A scatterplot of the collected data revealed a curved pattern with a possible cubic relationship (y=ax^3, where a is a constant) between the variables. Which of the following transformations would be most appropriate for creating linearity between the variables?

A - Taking the cube of y
B - Taking the cube root of y
C - Taking the cube root of both y and x
D - Taking the log of y
E - Taking the log of both y and x

Answers

Answer:

B - Taking the cube root of y

Step-by-step explanation:

Data provided in the question

y = ax^3

Based on the above information

Now we take the cube root of y

So, it would be calculated below:

y1/3 = a1/3 × x

So

As it can seen by the above equation there is a linear relationship between the cube root of y and x

Therefore, the correct option is B.

Hence, all the other options are wrong

Linearity is the concept used to describe linear relationships between variables.

The appropriate method for creating linearity between the variables is: (e) Taking the log of both y and x

The function is given as:

[tex]\mathbf{y = ax^3}[/tex]

The function is a power function (i.e. cube of x)

To create linearity between power function, we simply take the logarithms of both variables

So, we have:

[tex]\mathbf{\log(y) = a\log(x^3)}[/tex]

Apply law of logarithm

[tex]\mathbf{\log(y) = 3a\log(x)}[/tex]

Hence, the appropriate method for creating linearity between the variables is: (e) Taking the log of both y and x

Round to the nearest tenth: 0.087

Answers

Answer:

0.1

Step-by-step explanation:

When rounding, look at whether or not the number is less than 5, or greater than or equal to 5.

If it is greater than 5, you will round up to the next number.

In this number, 8 is greater than 5. This means to the nearest tenth, it will be rounded to 0.1

Answer:

0.1

Step-by-step explanation:

0.087

The number to the right of the decimal is always the tenth's place. To the left of the decimal is the one's place 8 is a high number, so you are rounding up because 5 or higher is always a high number. If it was a low number, you  round down because a low number is 4 and under.

B. {−3, 6, 24, 33}


C. {−63, −9, 99, 153}

D. {−0.5, 1, 4, 5.5}

Answers

Answer:

A. {−3.5, −2, 1, 2.5}

Step-by-step explanation:

Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:

y=9+6x

6x=y-9

[tex]x=\frac{y-9}{6}[/tex]

So we just insert the values, the first one being -12.

[tex]x=\frac{y-9}{6}\\x=\frac{-21}{6}\\x=\frac{-12-9}{6}\\x=-3.5[/tex]

So since from the options only A has -3.5 as an option that's the correct answer.

After a quick meeting with the chef, her first task was to make the broccoli quiches for the lunch special. By 6:15 AM, she had collected all the ingredients. She set salt, eggs, cream, butter, and cheese on the prep table. On her last trip to the cooler, she got the broccoli. It took over an hour to wash and chop it. Finally, Annie was able to make the quince filling. Leaving the leftover eggs and cream on the table, she got out the premade quiche crusts from the freezer and poured the filling. By the time she got the quiches in the oven, it was 10:45 AM.Twenty-five minutes later, Annie checked the quiches. They were supposed to bake for around 30 minutes. However, she did not want to overcook them. The chef said their internal temperatures needed to be 155. Annie used an infrared thermometer to check the temperature of one of the quiche in two places. The readings were in the correct range. She took the quiches out of the oven and set them on a table to cool.While the quiches cooled, Annie went to work making fruit salad. She washed her hands and put on gloves. As she headed back to the prep table with the melon, strawberries, and grapes, she noticed the eggs and cream she left out. She quickly put them back in the cooler. Then she wiped down the table and started prepping the melon.What did Annie do wrong? Hint: There are about 6-7 mistakes. 2.
