The yearbook club has 5 members returning from last year. They set up a booth in the cafeteria to recruit more members, and an a

verage of 3 new members sign up each day. Which best describes why the graph relating the total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be continuous or discrete?

Answer:

The graph will be discrete.

Step-by-step explanation:

There are 5 members from last year in the yearbook club.

Each day, an average of 3 additional members join.

Consequently, the total number of members increases by 3 each day.

This can be modeled using the equation:

m=5+3d

The series of member counts forms the sequence: 5, 8, 11, 14, 17........

Thus, we conclude that the graph represents a discrete function since the number of members is whole and the booth operates once per day.

Zina [12379]

Answer: The loss percentage per gallon is 23.17%

Step-by-step explanation:Original price per gallon is $ 2.59

Discounted price per gallon is $ 1.99

Now, we will calculate the percentage loss per gallon, using the Direct Rule of Three as follows:

Price      Percentage

2.59           100

1.99               x*****************************

2.59 * x = 1.99 * 100

2.59x = 199

x = 199/2.59

x = 76.83

So the percentage loss = 100 - 76.83

The percentage loss is 23.17%

Josiah works at an electronics store as a salesperson. Josiah earns a 2% commission on the total dollar amount of all phone sale
tester [12383]

Response: the equations are

0.02x + 0.07y = 156

y = 300 + x

Step-by-step explanation:

Let x denote the dollar amount from phone sales made by Josiah.

Let y indicate the dollar amount from his computer sales.

Josiah receives a 2% commission on his phone sales total and 7% on his computer sales. He accumulated a total of $156 in commission, leading to the equation

0.02x + 0.07y = 156 - - - - - - - - - - -1

Furthermore, it’s given that Josiah had $300 more in computer sales than in phone sales, expressed as

y = 300 + x

zzz [12365]

Answer:

Range = 16

Inter\ Quartile\ Range = 6.75

Variance = 20.44

Standard\ Deviation = 4.52

Step-by-step explanation:

Provided

4, 17, 12, 9, 6, 10, 1, 5, 9, 3

Calculating the range;

Range = Highest - Lowest

From the data provided;

The highest value is 17 and the lowest is 1

Thus;

Range = 17 - 1

Range = 16

Calculating the inter-quartile range

The inter-quartile range (IQR) is computed as follows

IQR = Q_3 - Q_1

Where

Q3 = Upper Quartile and Q1 = Lower Quartile

Start by sorting the data in ascending order

1, 3, 4, 5, 6, 9, 9, 10, 12, 17

N = Total data points; N = 10

---------------------------------------------------------------------------------

Calculating Q3

Q_3 = \frac{3}{4}(N+1) th\ item

Substituting 10 for N

Q_3 = \frac{3}{4}(10+1) th\ item

Q_3 = \frac{3}{4}(11) th\ item

Expressing 8.25 as 8 + 0.25Q_3 = \frac{33}{4} th\ item

Q_3 = 8.25 th\ item

Converting 0.25 into fractions

Q_3 = (8 + 0.25) th\ item

Q_3 = 8th\ item + 0.25 th\ item

From the ordered dataset;

Q_3 = 8th\ item +\frac{1}{4} th\ item and

Q_3 = 8th\ item +\frac{1}{4} (9th\ item - 8th\ item)

8th\ item = 109th\ item = 12

Q_3 = 8th\ item +\frac{1}{4} (9th\ item - 8th\ item)

Q_3 = 10 +\frac{1}{4} (12 - 10)

Q_3 = 10 +\frac{1}{4} (2)

Q_3 = 10 +0.5

Q_3 = 10.5

Calculating Q1

Substituting 10 for N

Q_1 = \frac{1}{4}(N+1) th\ item

Expressing 2.75 as 2 + 0.75

Q_1 = \frac{1}{4}(10+1) th\ item

Q_1 = \frac{1}{4}(11) th\ item

Q_1 = \frac{11}{4} th\ item

Q_1 = 2.75 th\ item

Converting 0.75 into fractions

Q_1 = (2 + 0.75) th\ item

Q_1 = 2nd\ item + 0.75 th\ item

From the arranged dataset;

and Q_1 = 2nd\ item +\frac{3}{4} th\ item

Q_1 = 2nd\ item +\frac{3}{4} (3rd\ item - 2nd\ item)

2nd\ item = 33rd\ item = 4

Q_1 = 3 +\frac{3}{4} (4 - 3)

Q_1 = 3 +\frac{3}{4} (1)

Q_1 = 3 +0.75

Q_1 = 3.75

---------------------------------------------------------------------------------

Remember that

IQR = Q_3 - Q_1

IQR = 10.5 - 3.75

IQR = 6.75

Calculating Variance

Begin by determining the mean

Mean = \frac{1+3+4+5+6+9+9+10+12+17}{10}

Mean = \frac{76}{10}

Mean = 7.6

Then subtract the mean from each value and square the differences

(1 - 7.6)^2 = (-6.6)^2 = 43.56

(3 - 7.6)^2 = (-4.6)^2 = 21.16

(4 - 7.6)^2 = (-3.6)^2 = 12.96

(5 - 7.6)^2 = (-2.6)^2 = 6.76

(6 - 7.6)^2 = (-1.6)^2 = 2.56

(9 - 7.6)^2 = (1.4)^2 = 1.96

(9 - 7.6)^2 = (1.4)^2 = 1.96

(10 - 7.6)^2 = (2.4)^2 = 5.76

(12 - 7.6)^2 = (4.4)^2 = 19.36

(17 - 7.6)^2 = (9.4)^2 = 88.36

Sum up the squared results

43.56 + 21.16 + 12.96 + 6.76 + 2.56 + 1.96 + 1.96 + 5.76 + 19.36 + 88.36 = 204.4

Then divide that sum by the total number of observations;

Variance = \frac{204.4}{10}

Variance = 20.44

Calculating Standard Deviation (SD)

SD = \sqrt{Variance}

SD = \sqrt{20.44}

SD = 4.52 (Approximated)
