Step-by-step explanation:

Answer:

34

Step-by-step explanation:

$1.25 = 125 cents.

$42 = 4200 cents

Tickets sold at 75 cents = x

Tickets sold at 125 cents = y

x + y = 40

75x + 125y = 4200

Multiply the first equation by 75

75x + 75y = 3000

75x + 125y = 4200

Subtract the the second equation from the first.

75x + 75y = 3000

- 75x + 125y = 4200

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

0 - 150y = - 1200

Divide both sides by - 150

-150y/-150 = -1200/-150

y = 8

Substitute y = 8 into the first equation

x + y = 42

x + 8 = 42

x = 42 - 8

x = 34

34 tickets were sold for 75 cents

8 tickets were sold for $1.25

Answer:

Waiter’s B Large Smoothies showed less variability.

Step-by-step explanation:

First, we have to find the mean for Waiter A’s and Waiter B’s Large Smoothies.

1) Mean

Waiter A

19.1 + 20.1 + 20.9 + 19.6 + 20.9 + 19.5 + 19.2 + 19.4 + 20.3 + 20.9 = 199.9

199.9 / 10 = 19.99

Waiter B

20.1 + 19.6 + 20.0 + 20.5 + 19.8 + 20.0 + 20.1 + 19.7 + 19.9 + 20.4 = 200.1

200.1 / 10 = 20.01

Now, we have to use the Mean Absolute Deviation (MAD) to find which waiter’s smoothies showed less variability.

Waiter A

I19.99 - 19.1I = 0.89

I19.99 - 20.1I = 0.11

I19.99 - 20.9I = 0.91

I19.99 - 19.6I = 0.39

I19.99 - 20.9I = 0.91

I19.99 - 19.5I = 0.49

I19.99 - 19.2I = 0.79

I19.99 - 19.4I = 0.59

I19.99 - 20.3I = 0.31

I19.99 - 20.9I = 0.91

0.89 + 0.11 + 0.91 + 0.39 + 0.91 + 0.49 + 0.79 + 0.59 + 0.31 + 0.91 = 6.3

6.3 / 10 = 0.63

Waiter B

I20.01 - 20.1I = 0.09

I20.01 - 19.6I = 0.41

I20.01 - 20.0I = 0.01

I20.01 - 20.5I = 0.49

I20.01 - 19.8I = 0.21

I20.01 - 20.0I = 0.01

I20.01 - 20.1I = 0.09

I20.01 - 19.7I = 0.4

I20.1 - 19.9I = 0.2

I20.1 - 20.4I = 0.3

0.09 + 0.41 + 0.01 + 0.49 + 0.21 + 0.01 + 0.09 + 0.4 + 0.2 + 0.3 = 2.2

2.2 / 10 = 0.22

Now, we just have to compare those numbers.

0.63 > 0.22

So, Waiter B’s smoothies show less variability.

6) a, b

7) a

8) b, c

10) I'm not sure but I believe it is C.

Step-by-step explanation:

Answer:

C. $16.99

Step-by-step explanation:

The shirt cost after the discount will be $16.99. thus option C is correct.

Third party discount is the multiplication result of the maturity value of the original rate to the rate of interest and time period.

Thus, we get:

Third party discount = Maturity value × R × T (R in decimal form).

We have been given that a shirt that normally costs $19.99 is on sale for 15% off. we are asked to find the discount on the shirt.

Therefore,

19.99 x 15/100

19.99 x 0.15 = 2.99

Then subtract from the total amount;

19.99 - 2.99 = 16.99

Therefore, the  shirt cost after the discount will be $16.99. thus option C is correct.

Answer:x = < 12/7

Step-by-step explanation:

Add 2 to both sides:

7x - 2 (+2) < 10 (+2)

7x < 12

Divide both sides by 7:

7x/7 < 12/7

X < 12/7

The solution to the inequality 7x - 2 < 10 is x < 12/7.

Given that an inequality 7x - 2 < 10 we need to solve the inequality,

we know that,

Inequality in mathematics refers to a mathematical statement that compares two quantities, expressing that one quantity is greater than, less than, or not equal to the other.

Inequality is denoted using various symbols, such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).

To solve the inequality 7x - 2 < 10, we'll isolate the variable x.

Let's start by adding 2 to both sides of the inequality:

7x - 2 + 2 < 10 + 2

Simplifying the expression:

7x < 12

Next, divide both sides of the inequality by 7 to solve for x:

(7x)/7 < 12/7

Simplifying further:

x < 12/7

Therefore, the solution to the inequality 7x - 2 < 10 is x < 12/7.
