Answer:
0.19975
Step-by-step explanation:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
Given:
n = 11
r = 9
p = 0.7
q = 0.3
Plugging in values:
P = ₁₁C₉ (0.7⁹) (0.3¹¹⁻⁹)
P = 0.19975

Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Find the value of XY
see the attached figure to better understand the problem
we know that
-----> by segment addition postulate
If X is the midpoint WY
then
substitute in the formula above
substitute the given values and solve for XY
Subtract 6 both sides
Divide by 2 both sides
Rewrite
