Answer: 3 were blue
Step-by-step explanation:
Blue + Red = 18....so.....
B + 5B = 18
6B = 18
B =18 / 6 = 3 blue
Answer:
C. 0.403
Step-by-step explanation:
Binomial distribution has two parameter n and p. Here, n=15 and p=0.60.
We have to find the probability of 10 or more will show that the hamburger, French fries and a drink were ordered. P(X≥10)=?
The binomial probability distribution function for random variable X is
where q=1-p=1-0.6=0.4,n=15 and p=0.6.
P(X≥10)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)
=0.185938
=0.126776
=0.063388
=0.021942
=0.004702
=0.000470
P(X≥10)= 0.185938
+0.126776
+0.063388
+0.021942
+0.004702
+0.000470
P(X≥10)=0.403216
So, the probability of 10 or more will show that the hamburger, French fries and a drink were ordered is 0.403.
Answer:
Step-by-step explanation:
Given function f(x) = 3x + 2
The inverse of f(x) is f⁻¹(x)
Follow the steps below to solve for f⁻¹(x).
1. Replace function f(x) with function y in the given equation
y = 3x + 2
2. Interchange the variables
x = 3y - 2
3. Solve for y
3y = x + 2
4. Replace y with f⁻¹(x)
