N+1-3n=5+n+1-2

Simplify it

-2n+1 = n+4

Add 2n to both sides

1 = 3n+4

Subtract 4 from both sides

-3 = 3n

Divide by 3

n = -1

N + 1 - 3n = -5 + n + 1 - 2

Combine like terms:

n - 3n = -2n

-2n + 1 = -5 + n + 1 - 2

Combine like terms:

-5 + 1 - 2 = -6

-2n + 1 = n - 6

Subtract 'n' to both sides:

-3n + 1 = -6

Subtract 1 to both sides:

-3n = -7

Divide -3 to both sides:

n = 2 1/3 or 7/3

In statistics, you may test a hypothesis using different statistical techniques like ANOVA or the F-test. You should have the null hypothesis, denoted as H0 and the alternative hypothesis, denoted as H1. Null hypothesis is the hypothesis you would like to test on. This is called as such because this is the hypothesis statisticians would like to test to nullify. This would be p < 5.8%. On the other hand, the alternative hypothesis is the contrary of the null hypothesis. Hence, the alternative hypothesis is p ≥ 5.8%. The answer is C.

beks73 [17]

Answer:

$675

Step-by-step explanation:

Let

x = original price of laptop

Discount = 10%

Actual price paid = x - 10% of x

= x - .10x

= .90x

Cost of mouse = $13.99

Total amount paid = $621.49

Total amount paid = actual cost of laptop + Cost of mouse

621.49 = .90x + 13.99

621.49 - 13.99 = .90x

607.5 = .90x

x = 607.5 / .90

= 675

Original cost of the laptop = $675
