Answer:
64.80
Step-by-step explanation:
The new price will equal the original price plus the markup.
The markup equal the original price * the markup percentage
markup = 54*.2
markup = 10.8
New price = original + markup
New price = 54+10.8
New price = 64.80
Answer:
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee hi
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. isolate x by adding 7 to the other side (7+4)
5x - 7 = 4
5x = 11
2. divide by 5 to get x alone
x = 11/5
<span>Formula: probability = number of positive outputs / total number of possible events
Randomly
picking a green card from a standard deck of playing cards.
A standard deck of playing cards does not have green cards, so the probability is 0.
3. randomly
picking a red card from a standard deck of playing cards
Half of the cards from a standard deck of playing cards are red, so the probability is 0.5.
4. picking a
number less than 15 from a jar with papers labeled from 1 to 12
All the papers have a number less than 15, so the probability of picking a number less than 15 is 1.
5.
picking a number that is divisible by 5 from a jar with papers labeled
from 1 to 12
The numbers divisible by 5 from 1 to 12 are 5 and 10, so there are two positive outputs from a total of 12 possible events and the probabily of picking a number that is divisible by 5 is 2 / 12 = 1/6.
Answr: 1/6.
use the complement to find each probability. (example 3)
8.
what is the probability of not rolling a 5 on a standard number cube?
The probability of rolling a 5 is 1 out of 6 = 1/6
The complement is 1 - 1/6 = 5/6.
Therefore, the probability of not rolling a 5 is 5/6.
9.
a spinner has 3 equal sections that are red, white, and blue. what is
the probability of not landing on blue? 1
The probability of landing on blue is 1 / 3. The complement is 1 - 1/3 = 2/3.
Therefore, the probability of not landing on blue is 2/3.
2. describe an event that has a
probability of 0% and an event that has a probability of 100%.
essential question check-in ??
Rolling a 7 with a standard cube has probability 0%.
Rolling a number different from 7 from a standard cube has a probability of 100%.
10. a spinner has 5 equal sections marked
1 through 5. what is the probability of not landing on 4?
Each section has a probability of 1/5.
So not landing on 4 has a probability of 1 - 1/5 = 4/5.
11. there are
4 queens in a standard deck of 52 cards. you pick one card at random.
what is the probability of not picking a queen?
Picking a queen has probability of 4/52 = 1/13.
The complement is 1 - 1/13 = 12/13.
Therefore, the probability of not picking a queen is 12/13.
