Answer is a if I am not mistaken
Answer:
B
Step-by-step explanation:
x² - 4x - 7 = 0
(x - 2)² = 11
Answer:
0.83193
Step-by-step explanation:
Probability of having the Rhesus (Rh) factor present in their blood; p = 0.3
Sample size; n = 5
We want to find the probability the probability that at least one does not have the Rh factor.
This will be;1 - P(X < 1)
This is a binomial probability distribution. Thus;
P(X = k) = C(n, k) × p^(k) × (1 - p)^(n - k)
P(X < 1) = P(X = 0)
Thus;
P(X = 0) = C(5, 0) × 0.3^(0) × (1 - 0.3)^(5 - 0)
P(X = 0) = 1 × 1 × 0.16807
P(X = 0) = 0.16807
Thus;
1 - P(X < 1) = 1 - 0.16807 = 0.83193
You may write them separating the units and tens digits, and then use FOIL to add 4 easy tems. For example, let's compute :
Answer:
2203.20 pesos
Step-by-step explanation:
Joe's original amount was $200
#We convert this amount to $CDN:
Joe now has to convert the Canadian dollars to Mexican pesos(at a rate of 10.8 pesos per $1 CDN):
Hence, he gets a total of 2203.20 pesos in exchange for his Canadian dollars.
