Answer:
The required probability is 0.0155.
Step-by-step explanation:
We are given that the one-year survival rate for pancreatic cancer is 20%.
Of 12 people diagnosed with pancreatic cancer at one hospital, 6 survived one year.
The above situation can be represented through binomial distribution;
where, n = number of trials (samples) taken = 12 people
r = number of success = 6 survived
p = probability of success which in our question is probability of
one-year survival rate for pancreatic cancer, i.e; p = 20%
Let X = <u><em>Number of people survived one year</em></u>
So, X ~ Binom(n = 12 , p = 0.20)
Now, the probability that 6 survived one year is given by = P(X = 6)
P(X = 6) = 
= 
= <u>0.0155</u>
15% * 8 cups
= 0.15 * 8 cups
= 1.2 cups
Answer:
Marisa can rent 10 movies this month including the $5.00 membership fee. Not including the membership fee she could rent 14 movies this month. Her mistake is was rounding the 10.8 up when she should have rounded it down, unless she can get 10 8/10 of a movie.
Step-by-step explanation:
Answer:
So,
2t + 7 = -1
-7 -7
2t = -8
2t/2 = -8/2
<u>t = -4</u>
Step-by-step explanation:
Answer:
f(1)=-4
Step-by-step explanation:
f(1) means what is the y in the point on the curve of f so that x=1.
So I go to x=1 on the x-axis.
So I go right one from the origin.
I notice the curve is below the x-axis so I go down to the curve til I get to the curve.
Once I get to the curve, I look at the y-axis to tell what that number is for that ordered pair there at x=1.
That y-value is -4.
A graph/picture is probably worth a lot more to you then my words.
Other examples:
f(2)=-5
f(3)=0
f(-1)=4
f(-2)=5
f(-3)=0
