Answer:
We know that n = 50 and p =0.78.
We need to check the conditions in order to use the normal approximation.
Since both conditions are satisfied we can use the normal approximation and the distribution for the proportion is given by:
With the following parameters:
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
We know that n = 50 and p =0.78.
We need to check the conditions in order to use the normal approximation.
Since both conditions are satisfied we can use the normal approximation and the distribution for the proportion is given by:
With the following parameters:
Answer:
= - 95n
Step-by-step explanation:
Note the difference between consecutive terms in the sequence is constant
- 190 - (- 95) = - 190 + 95 = - 95
- 285 - (- 190) = - 285 + 190 = - 95
- 380 - (- 285) = - 380 + 285 = - 95
This indicates that the terms are an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 95 and d = - 95, thus
= - 95 - 95(n - 1) = - 95 - 95n + 95 = - 95n
Answer:
0.2 × 10^-5 31.4
Step-by-step explanation:
Answer:
X= 4c The absolute value you can find witht the equation |4c|
Oh, use SOH - CAH - TOA
Sin x = Opposite / Hypotnuse
Cos x = Adjacent / Hypotnuse
Tan x = Opposite / Adjacent
So for #1, for example:
Sin A = 15/17
15/17 would be your answer.
