Answer:
75%
Step-by-step explanation:
You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Given the following
Total cards = 4 (6,7,8,9)
If the card is not 9, the required card will be (6,7,8)
Number of cards that are not 9 is 3
Probability = expected/total
Pr(not 9) = 3/4
express as percent
Pr(not 9) = 3/4×100
Pr(not 9) = 75%
Answer:
4
Step-by-step explanation:
Let the smaller number be x and the larger one be y
x + y = 77
y = x + 5
Substituting into the first equation
x + (x + 5) = 77
2x + 5 = 77
Subtracting 5 to both sides
2x +5 -5 = 77-5
2x = 72
Divide both sides by 2
2x/2 = 72/2
x = 36
A) 2.85g+3.15c
B)2.85(8.4)+3.15(6)=$42.84
