90≤4x+30
Yes she will have enough. 4 multiplied by 18 is 72. 72+30=102.
Hope this helped.
Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

Maybe step 3 because you try to get rid of the x on both sides
Answer:
(2,3)
Step-by-step explanation:
The solution to a linear system is always where both of the lines intersect.
Answer:
v = C/p^2.
Step-by-step explanation:
C = v * p ^ 2
Divide both sides by p^2:
v = C/p^2.
