All students = 700
Sedaia [141]

Answer:

  • See below

Step-by-step explanation:

<u>Given:</u>

  • Total number = 700
  • Off grid class = 450
  • Online class = 320
  • Both = 275

<u>Based on the given we find the following</u>

1) <u>Off-grid class only:</u>

  • 450 - 275 = 175

3) <u>Online class only:</u>

  • 320 - 275 = 45

2) <u>None of the classes:</u>

  • 700 - (175 + 275 + 45) = 205

4) <u>Not online:</u>

  • 700 - 320 = 380

5) <u>Not off-grid:</u>

  • 700 - 450 = 250

2. Write a recursive formula for the sequence 5, 18, 31, 44, 57, ... Then find the next term.
ludmilkaskok [199]

Answer: a6=70

Step-by-step explanation:

we know that

In the Arithmetic Sequence the formula is:

an= a1 + d(n−1)

where

a1 is the first term

d is the common difference

n is the number of terms

in this problem

a1=5

a2=18

a3=31

a4=44

a5=57

so

d=a2-a1 or a3-a2 or a4-a3 or a5-a4

d=57-44----> 13

find a6

a6= a1 + d(n−1)

n=6

d=13

a1=5

a6=5+13*(6-1)----> a6=5+13*5----> a6=70

You purchased a new car for 17,999 in the year 2015. It is now 2020 and you want to sell your car for a fair price. If your car
salantis [7]

Answer:

$7,986.25

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value</em>

<em>r = rate (decimal)</em>

<em>t = time (years)</em>

<em />

First, change 15% into a decimal:

15% -> \frac{15}{100} -> 0.15

Since 2015 and 2020 are 5 years apart, we will use 5 for t. Now, plug the values into the equation:

A=17,999(1-0.15)^5

A=7,986.25

Your car would be worth $7,986.25
