x^2+4-5
Step-by-step explanation:
the first box multiply the next box
x^2-1x+5x-5
x^2+4x-5
2 dollars is 17% converted
Answer:
good questiion
Step-by-step explanation:
Please don't ask 2 questions in 1 question
remember that percent is parts out of 100 so x%=x/100
basically just remove the percent sign and move the decimal place 2 places to the left to convert to fraction
the first one
20 dollars
4.75% tax
15% tip
it depends if you want to tip on the total with tax or without tax
it is better to top on the without-tax value since tax comes from you so
find 4.75% of 20 and add that to 15% of 20 then add that to 20 to get the proper value
scenarios
1. 20+(20 times 4.75%)+(20 times 15%)=23.95
2. ([(20 times 104.75%)] times 115%)=24.09
both are bellow $25 so $25 shoudl be enough to cover it
total cost of a spa treatment of 42 with 6% tax and 20% tip
so you could again do two things:
1. apply tax and give tip on the new amount
2. find the tip and add that to the tax of only 42
scenarios:
1.(42 times 106%) times 120%=$50.4
2. (42 times 20%) +(42 times 106%)=$52.92
it depens on what you tip on
Answer:
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
Step-by-step explanation:
Given that an experimental drug is administered to 90 randomly selected individuals, with the number of individuals responding favorably recorded.
We find here the no of trials are 90 but we cannot say the probability is the same for all trials.
In other words, each individual may have a different probability to respond.
Since p , the success for each trial may differ for each trial binomial cannot be accepted
C. No, because the trials of the experiment are not independent because the probability of success differs from trial to trial.
