Answer:
Step-by-step explanation:
Since we are dealing with binomial probability in this scenario, then the outcome is either a success or a failure. A success in this case means that a chosen adult has a bachelor's degree. The probability of success, p would be 20/100 = 0.2
The number of adults sampled, n is 100
The number of success, x is 60
The probability that more than 60 adults have a bachelor's degree P(x >60) would be represented as
d. P(x<60)=binomcdf (100.0.20.60)
binompdf is used when we want to determine P(x = 60)
Answer:
I am going to show you the first steps to complete squares for the given equation: 1) Starting equation: 3x^2 + 9x -4 = 0 2) Add 4 to both sides => 3x^2 + 9x - 4 + 4 = 4 => 3x^2 + 9x = 4 3) Extract common factor 3 in the left side => 3 (x^2 + 3x). Now, compare with a(x^2 + 3x) and you get a = 3. Answer: a = 3.
Answer:
100+0.30p
hope this helps
have a good day :)
Step-by-step explanation:
(184-94)/5=18
This means that she fills up 18 liters every minute. Thus she will be done in->
184(original amount)+(2 minutes (time passed during first data point)*18(rate of water)=184+36=220
To find the total time taken we divide 220 by 18 which is 220/18=12 2/9
