4/5 ÷ 12 = 4/5 x 1/12 = 4/60 = 1/15
Answer: 1/15 m
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18
Answer:
If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. If it is not a binomial experiment, explain why. You darw 5 cards one at a time from a standard deck you do not replace a card once it is drawn. The
Approximately 3365 students will score less than 66.
The z-score is calculated using the formula
z=(X-μ)/σ, where μ is the mean and σ is the standard deviation.
For this problem, we have
z=(66-57)/9 = 9/9 = 1.00
Using a z-table (http://www.z-table.com) we see that the area to the left of, or probability less than, this is 0.8413.
To find the number of students out of 4000 that will score in this range, we multiply this probability by 4000:
0.8413(4000) = 3365.2 ≈ 3365
