If the Pr (A)=0.3 what is Pr (A’)

Answers

Answer:

0.7

Step-by-step explanation:

I assume Pr is for Probability and A' is "not A" (complementary probability)

Pr(Anything)=1

Pr(A)=0.3

Pr(A')=1-Pr(A) (anything but A)

Pr(A')=1-0.3

In mathematics, input and output are terms that relate to functions. Both the input and output of a function are variables, which means that they change. ... A simple example is y = x2 (which you can also write f(x) = x2). In such cases, x is the input and y is the output.

Answers

w-13=15|+13
w=15+13

The terms are 4/10, n/30. The net price is $919.60. What is the cash price using the complement method? '

Answers

Answer:

Cash price using complement method id $882.8

Step-by-step explanation:

When a vendor includes terms of 4/10, n/30 , the '4' represents 4% of the amount owed , the '10' represents 10 days, the 'n' represents net and the '30' represents 30 days.

So the terms 4/10, n/30 indicate that the buyer may take an early discount of 4% of the amount owed is remitted in 10 days instead of normal 30 days.

In other words, buyer can choose any one of the following:

1) Pay within 10 days and deduct 4% of the net amount owed.

2)Pay in 30 days and take no discount.

For finding cash price using complement method, we have to find the complement of discount percentage= 100-discount percentage=100-4=96

So cash price using complement method = net price X complement of discount percentage in decimals

= 919.6 X 0.96

= $882.8

5a -5=7+2+2a I really need help

Answers

5a-2a=7+2+5
a(5-2)=14
a=14/5-2
a=14/4
a=3.5

Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)
