Increase is a term used for add. So we have to find the number that is increased by 10 to make 114. So take 10 from 114 and you will get the answer.
Answer:
30 one-dollar bills and 12 five-dollar bills.
Step-by-step explanation:
Let x represent number of one-dollar bills and y represent number of five-dollar bills.
We have been given that a tip jar contains x one-dollar bills and y five- dollar bills. There are 42 bills in the jar. We can represent this information in an equation as:
We are also told that the total value of all bills is $90.00. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, there are 12 five-dollar bills in the tip jar.
Upon substituting in equation (1), we will get:
Therefore, there are 30 one-dollar bills in the tip jar.
Answer: the normal curve can be used as an approximation to the binomial probability considering the following condition: when the sample is large, in this case n=112
Step-by-step explanation:
for a binomial experiment to be approximated to normal distribution, the following conditions must be present:
i. sample size must be large, in this case sample size is 112
ii. the mean must be equal to np,where n is sample size and p is probability of success
iii. the standard deviation must be equal to npq,where q is the probability of failure
First one subtract 4/5 and 3 3/4 then divide both sides by the number you get from subtracting.
13.7*1/10=1.37 So far she has hiked 1.37 miles.
