If 2 books cost $14 each, 14 x 2 = 28 and with the $2 tax, it would be 28 + 2 = 30

She payed $30 in all

Each book is $14, so two books would be $28. Add $2 in tax, and you get $30. She payed $30. Hope this helps!

The tiles that Bruce used were each of a square foot in the area. The table shows the area covered by Felicia’s tiles in terms o

Allisa [31]

Answer:

Step-by-step explanation:

We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.

Let x= Number of tiles

y=Area covered by Felicia's tile

$x_1=9, x_2=18, x_3=27$

$y_1=1, y_2=2,y_3=3$

$\frac{x_1}{y_1}=\frac{9}{1}=9$

$\frac{x_2}{y_2}=\frac{18}{2}=9$

$\frac{x_3}{y_3}=\frac{27}{3}=9$

The ratio of x and y remains constant.Therefore, it is direct proportion .

Equation of direction proportion is given by

$\frac{x}{y}=k$

Where

k=The value of ratio of x and y

x and y are variables

We have k=9

Substitute the values in the equation

Then, we get

$\frac{x}{y}=9$

$x=9y$

$y=\frac{1}{9}x$

This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.

Find the difference. (k2−7k+2)−(k2−12)

Ostrovityanka [42]

Answer:

-7k + 14

Step-by-step explanation:

(k² - 7k + 2) - (k² - 12)

k² - 7k + 2 - k² + 12

k² - k² - 7k + 2 + 12

-7k + 14

Exclude leap years from the following calculations. (a) Compute the probability that a randomly selected person does not have a

Scrat [10]

Answer:

a) 99.73% probability that a randomly selected person does not have a birthday on March 14.

b) 96.71% probability that a randomly selected person does not have a birthday on the 2 nd day of a month.

c) 98.08% probability that a randomly selected person does not have a birthday on the 31 st day of a month.

d) 92.33% probability that a randomly selected person was not born in February.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

A non-leap year has 365 days.

(a) Compute the probability that a randomly selected person does not have a birthday on March 14.

There are 365-1 = 364 days that are not March 14. So

364/365 = 0.9973

99.73% probability that a randomly selected person does not have a birthday on March 14.

(b) Compute the probability that a randomly selected person does not have a birthday on the 2 nd day of a month.

There are 12 months, so there are 12 2nds of a month.

(365-12)/365 = 0.9671

96.71% probability that a randomly selected person does not have a birthday on the 2 nd day of a month.

(c) Compute the probability that a randomly selected person does not have a birthday on the 31 st day of a month.

The following months have 31 days: January, March, May, July, August, October, December.

So there are 7 31st days of a month during a year.

Then

(365-7)/365 = 0.9808

98.08% probability that a randomly selected person does not have a birthday on the 31 st day of a month.

(d) Compute the probability that a randomly selected person was not born in February.

During a non-leap year, February has 28 days. So

(365-28)/365 = 0.9233

92.33% probability that a randomly selected person was not born in February.
