Answer:

2.5 inches per year

Step-by-step explanation:

We can deduce the rate of change by obtaining the slope or gradient of thw points given :

Gradient = Rise / Run.

Point A (2, 5) ; point B (4, 10)

x1 = 2 ; y1 = 5 ;x2 = 4 ; y2 = 10

Rise = y2 - y1 = 10 - 5 = 5

Run = x2 - x1 = 4 - 2 = 2

Rate of change = Gradient = 5 /2 = 2.5

Which is 2.5 inches per year

<h3>What is arithmetic?</h3>

Mathematics' arithmetic discipline focuses on the study and application of numbers, their relationships, and observations on them.

The word "arithmetic," which is derived from the Greek word "arithmos," or "number," generally refers to the fundamental concepts in number theory, measurement, and computation (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

However, how it has been applied mathematically has not always been consistent. Carl Friedrich Gauss, a renowned German mathematician, first used the term to refer to more complex topics in his Disquisitiones Arithmeticae (1801), and other mathematicians still use it today.

Referrals to the article number theory are made to readers who are interested in the latter.

Our monthly gross salary is $2770.22

So our semi-monthly salary = 2770.22/2

                                             = 1385.11

Social security payment = 6.2% × 1385.11

                                         = $85.87

                                         =  171.74

Medicare payment = 1.45%  × 1385.11

                                = $20.08

=                                   = 40 .16

Monthly expenses = $1200

State tax semi monthly = $52

State tax Monthly = $104

Federal tax semi monthly = $101

Federal tax monthly  = $202

Adding all these monthly expense we get a total of

171.74 + 40 .16 + 1200 + 104 + 202

=  1717.9

His saving every month = 2770.22 - 1717.9

                                        = 1052.32

Salary saved in 7 months = 1052.30 × 7

                                           = 7366.10

Thus, The correct option is A. 7366.10, Yes, we have saved enough money to visit Spain in august.

Mean = sum of the score/Total math subjects offered

Mean = 95+ 90+85+40+100+100+85+90/8

Mean = 685/8

Mean = 85.6

Hence her overall performance is 85.6%

The measure of central tendency used is 85.6%
