Answer 1

Answer:

a. To find the relative frequency of people that chose romance, we need to count the number of times the letter "R" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "R" appears in the sequence is: R, R, R, R, R, R, H, R = 7

The total number of letters in the sequence is: 26

Relative frequency of people choosing romance = 7/26 = 0.269 or approximately 0.27.

b. To find the relative frequency of people that chose comedies, we need to count the number of times the letter "C" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "C" appears in the sequence is: C, C, C, H, C, C, H, H, C, C = 9

The total number of letters in the sequence is: 26

Relative frequency of people choosing comedies = 9/26 = 0.346 or approximately 0.35.

c. To find the relative frequency of people that chose horror, we need to count the number of times the letter "H" appears in the given sequence and divide it by the total number of letters in the sequence.

The number of times "H" appears in the sequence is:

H, H, H, H, H, H, H = 7

The total number of letters in the sequence is: 26

Relative frequency of people choosing horror = 7/26 = 0.269 or approximately 0.27.

g. Based on the relative frequencies calculated, it can be seen that comedies is the most popular movie genre among the class, as it has the highest relative frequency of 0.35.

h. Based on the relative frequencies, it can be seen that romance is the least popular movie genre among the class, as it has the lowest relative frequency of 0.27. Hence, if we were having a party for the class, we would be least likely to pick romance as the genre of movie to watch.

Use the graph of f to evaluate the following
The average rate of change of f from 2 to 5

Answers

By using the graph, the average rate of change of the function f from 2 to 5 is equal to -1.

How to determine the average rate of change?

In Mathematics, the average rate of change of f(x) on a closed interval [a, b] is given by this mathematical expression:

Average rate of change = [f(b) - f(a)]/(b - a)

Next, we would determine the average rate of change of the function f from the graph over the interval [2, 5]:

a = 2; f(a) = 4

b = 5; f(b) = 1

Substituting the given parameters into the average rate of change formula, we have the following;

Average rate of change = (1 - 4)/(5 - 2)

Average rate of change = -3/3

Average rate of change = -1.

Mike bought several packs of lacrosse trading cards to add to his collection
to pay for his cards packs , he paid with 1 quarter, 2 dimes 4 nickels and 4 pennies
What was the cost of the packs of cards that mike bought ?

Answers

The cost of the packs of cards that Mike bought can be calculated by adding up the value of the coins he used to pay for them.

1 quarter is worth 25 cents.

2 dimes are worth 2 * 10 cents = 20 cents.

4 nickels are worth 4 * 5 cents = 20 cents.

4 pennies are worth 4 cents.

So, the total value of the coins that Mike used to pay for the packs of cards is 25 + 20 + 20 + 4 = 69 cents.

Therefore, the cost of the packs of cards that Mike bought was 69 cents.

A bakery is selling breakfast platters. A platter of 12 bagels costs $10.20. Additionally, it costs $4.65 for a gallon of coffee. What is the slope of this situation? 10.20 4.65 0.85 0.12

Answers

The slope of the given situation of selling breakfast platters is 0.90.

What is slope?

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

Given, the platter of 12 bagels costs $10.20.

The extra cost of  $4.65 for a gallon of coffee.

To find the slope of the situation, we convert the situation into the equation of the line.

y=mx+c

here c is the extra cost that is 4.65

12m=10.20

For 12 bagels , the cost is 10.20,

then the slope will be the cost of each bagel.

m=10.20/12

m=0.85

m=$0.85

Therefore, option c 0.85 is the slope of the given situation of the bakery selling the breakfast platter of 12 bagels and a gallon of coffee.

Answers

Solution of 1 1/2 + 2 3/7 is 3 13/14

What is mixed number?

A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given expression,

1 1/2 + 2 3/7

it can be written as

= 3/2 + 17/7

= (21 + 34)/14

= 55/14

= 3 13/14
