Step-by-step explanation:

anonymous is another word for unknown, i learned this in gamer talk ;P

Answer: Unknown.

Step-by-step explanation: When any author is anonymous whether they write myths, legends, short stories, etc, it means that their name is hidden or unknown.  If you looked it up online, it would tell you this, "(of a person) not identified by name; of unknown name."  Therefore, anonymous means an author not identified who is unknown.

84.78 inches cubed  - hope this helped :)

Step-by-step explanation:

formula - πr^2[tex]\frac{h}{3}[/tex]

3 x 3 x 3.14 = 28.26

28.26 x 9/3

28.26 x 3

answer = 84.78

Answer:

84.78 inches cubed

Step-by-step explanation:

You need to comprehend the volume formula for cones

Volume Formula for Cones: V=1/3hπr²

Your measurements:

9 inches for height

3 inches for radius

**Radius is half of a circle and diameter is full of the circle/base.***

Equation:V=1/3 x 9in x π x 3²

You should do 3 squared first so that you can input it into your calculator easily.

V=1/3 x 9in x π x 9

Now on a calculator do 1 divided by 3 which is the "1/3" in the formula.

Then multiply 9, 3.14 for pi, and 9 for radius.

Note: You should do 3.14 for pi not the whole pi symbol on the calculator.

Your answer: 84.78 in cubed

Using proportions, it is found that:

A proportion is a fraction of a total amount.

Item a:

The sum of the frequencies is of 1, hence, the table is completed with 1 - (0.55 + 0.35) = 0.1.

Item b:

Considering that there were n games, we have that:

The difference was of 15, hence:

0.55n - 0.35n = 15

0.2n = 15

n = 15/0.2

n = 75

Answer:

60 marshmallows and 30 crackers

Step-by-step explanation:

Each girl brought a bag of marshmallows containing 30 marshmallows inside. 2 x 30 = 60 marshmallows altogether.

Since there are 15 s'mores, we have to distribute the marshmallows equally.

60 ÷ 15 = 4 marshmallows in each. But if we multiply that again ( 15 x 4 ) we get 60 again. Thus, they used 60 marshmallows altogether.

The girls make 15 smores. A s'more has two crackers inside one.

2 x 15 = 30 crackers.

Hope this helped.

Answer:

60 marshmallows and 30 crackers

explanation:

1. 15 x 4 = 60

60 divided by 15 = 4

2. 15 x 2 = 30

Answer: 30 degrees

Step-by-step explanation:

90 degrees / 3 angles = 30 degrees

Answer:

First, the student performed what was inside of the parentheses and was exponential, which is correct. We know this because of the rules called order of operations, outlined by PEMDAS, which tells us to perform mathematical operations in the following order: parentheses, exponents, multiplication, division, addition, subtraction.

So by the rules I just outlined, next the student should have performed the multiplication, but instead performed subtraction, which is incorrect.

The following is the correct simplification of the expression:

23 - 8 times 2 + 3 by the power of 2

So first we should perform parentheses, but there are none. So we move to the next option in the list, which is exponents, which we do have (3^2).

23 - 8 * 2 + 3^2

23 - 8 * 2 + 9

Next in PEMDAS comes multiplication and division. This means the next step in simplifying the expression is to evaluate 8*2.

23 - 16 + 9

Next in PEMDAS is addition, so we should perform the operation -16 + 9.

23 - 7

Finally, the last step in PEMDAS is to simplify the remaining operation (subtraction).

16

Therefore, the student did the first step correctly but performed the second step incorrectly. The final answer should be 16 after simplification.

Hope this helps!

Answer:

This method is incorrect.

Step-by-step explanation:

The student's understanding of an exponent -1 is correct, but applying it to the inverse function f^-1(x), is wrong.

The method to find inverse function is to replace f(x) with y, switch x and y, then solve for y.

To use the (incorrect) "simple method" Put a 1 on top and move the function to the bottom (denominator).

For example, let's look at the function f(x) = x+3

Write y in place of f(x).

y = x + 3

Switch x and y.

x = y + 3

Solve for y.

Subtract 3.

x - 3 = y

Rewrite.

y = x - 3

This is the proper inverse function.

f^-1 (x) = x - 3

Using the (incorrect) "simple method"

f(x) = x + 3

f^-1(x) = 1/(x+3)

This shows that the shortcut doesnot work, its wrong. To do it correctly, switch x and y and solve for y.

Answer:

B.

Mean: 16.1

Median: 16

Mode: 16

Step-by-step explanation:

First, order the numbers in the data set from least to greatest:

[tex]14 , 14 , 14 , 14 , 15 , 15 , 15 , 15 , 15 , 16 , 16 , 16 , 16 , 16 , 16 , 17 , 17 , 17 , 19 , 19 , 19 , 19[/tex]

First, find the mean. The mean of a data set can be found by adding all the numbers together and dividing by the amount of numbers in the set:

[tex]\frac{14 + 14 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 16 + 16 + 16 + 16 + 17 + 17 + 17 + 19 + 19 + 19 + 19}{22} = \frac{354}{22}[/tex]

Next, simplify by dividing:

[tex]\frac{354}{22} = \frac{177}{11} = 16 \frac{1}{11} or ~16.1[/tex]

Mean: 16.1

Next, find the median. The median is the number(s) directly in the middle. If there is a even amount of number in the data set, find the mean of the two median numbers:

Median: 16 , 16

Median = [tex]\frac{16 + 16}{2} = \frac{32}{2} = 16[/tex]

Median = 16

Next, find the mode. The median is the number that shows up the most. In this case, it is 16, which appears 6 times, 1 more time then the next number that appears the most 15, which appears 5 times.

Mode: 16

The function is a linear function, and the equation of the function when squared is (f(x))² =25(4x²)

The equation of the function is given as:

f(x) = 5(2x)

When the function is squared, we have:

(f(x))² =(5(2x))²

Evaluate the exponent

(f(x))² =25(4x²)

Hence, the equation of the function when squared is (f(x))² =25(4x²)
