Answer: 155 fifth grader students.
Step-by-step explanation:
Given that 80% = 124 fifth grader students, the difference between 80% and total number of fifth grader students is 100% - 80%, which is 20%.
Therefore, if 80/100 = 124
(100/100- 80/100) = x
We cross multiply:
0.8x = 0.2 x 124
0.8x = 24.8
Divide both sides by 0.8
x = 24.8/0.8
x = 31
Total number of fifth grader students is 124 + 31 = 155
Answer:
The first option: As the x-values go to positive infinity, the function's values go to negative infinity.
Step-by-step explanation:
Let's focus on the right part of the graph. Notice that at x = 1, the line is on the negative y-axis. The same thing happens to when we locate x = 2, it still continues to go down approaching negative infinity.
Answer: 33x square units
Step-by-step explanation:
We don't know what x is but we can still place it as our answer.
11 times 3x is 33x.
33x/3 =11 (check)
The number of payments per year is 12
The number of payments is 36 which means that the term lasted for 3 years.
The total interest is $158.15 and the amount financed is $2500.
The interest rate is
158.15/2500 = 6.33%
In nominal month, that is
(1 + r/12)^12 - 1 = 0.0633
Solve for r
Answer:
The probability is
Step-by-step explanation:
We are going to modeled this problem from the number of heads.
Let be H : ''The number of heads after five flips''
H can assume the following values :
h = 0
h = 1
h = 2
h = 3
h = 4
h = 5
H ~ Bi (n,p)
H ~ Bi (5,0.5)
H can be modeled as a Binomial random variable.
In which p = 0.5 is the success probability (the probability of head in one flip of a fair coin)
n = 5 is the number of times that we flip the coin.
We are also assuming independence in each flip.
The probability function for H is
For all the possible values of H
H ≥ 3 is the event that puts Polya on the 7th floor or higher.
Now we calculate the probability of H ≥ 3
Therefore, the probability of each of her next five stops is on the 7th floor or higher is
