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
Answer:
y=2
Step-by-step explanation:
Answer:
p= a +2b
Step-by-step explanation:
Making p the subject of the equation means that we need to arrive at the final answer of p= ____.
a= p -2b
a +2b= p <em>(</em><em>+</em><em>2b</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
p= a +2b
So if x= number of trees, and y= rental applications, the owner wants to see if increasing x will increase y. The correlation coefficient is between -1 and 1. If the number of trees really does have a positive impact on rental applications, the correlation coefficient would be close to 1. If there is absolutely no relationship, the coefficient would be near zero. If planting trees causes a DECLINE in rental applications, the coefficient would be close to -1.
Answer:
Step-by-step explanation:
Area of the shaded region = Area of the square with side 25 ft - Area of the semicircle with radius (25/2) = 12.5 ft.
