Answer:
0.18173219.
Step-by-step explanation:
We have been asked to find what will be the probability that at least 6 of 9 adults use their smartphones in meetings or classes.
We will find our answer using Bernoulli's trails.
First of all we will find the probabilities when r is 6, 7,8 and 9 then we will add them all.
When r=6,
Similarly we will find Probabilities when r=7, 8 and 9.
When r=7
When r=8
When r=9,
Now let us add all the probabilities to get the final answer.
Therefore, probability that at least 6 of 9 adults use their smartphones in meetings or classes is 0.18173219.
The answer is cot² ∅ - csc² ∅ = -1
Referring to Pythagorean identities:
sin² ∅ + cos² ∅ = 1
1+cot² ∅ = csc² ∅
tan² ∅ + 1 = sec² ∅
1+cot² ∅ = csc² ∅
⇒ transposing 1 and csc² ∅ we will have now
cot² ∅ - csc² ∅ = -1
Answer:

Answer:
(0, 3)
Step-by-step explanation:
(0, 3) is the following is the midpoint between (3, 2) and (-3, 4)
Answer:
An exponential function is a function in the form of f(x) = bx or y = bx (if we wish to express the function in terms of y instead of f(x)), where b > 0, b ≠ 1 and x is a ... the interval (-∞, ∞) is because any real number can be put in for x the function f(x) ... zero and negative numbers are not part of the range is because any positive
