1.31-1.00=.31 move the decimal place to the left 31%
Answer: B. binomial.
Step-by-step explanation:
1. You can classify polynomials based on the number of terms the polynomial has:
- If it has one term is classified as a monomial.
- If it has two term is classified as a binomial.
- If it has three terms is classified as a trinomial.
2. The polynomial
has two terms. Therefore, the correct clasification is: binomial.
3. Then, the correct answer is the option B.
Answer:
x = 55.866 ft.
Step-by-step explanation:
39^2 + 40^2 = x^2
1521 + 1600 = 3121
sqrt(3121) = 55.8659
Rounded = 55.866
Make sure to add the ft.
Answer:
0.082
Step-by-step explanation:
Number of attempts = n = 100
Since there are only two outcomes and in-dependent of each other, the probability of missing a shot = 1 - Probability of making each shot
p = 1 - 0.95 = 0.05
Possion Ratio (λ) = np where n is the number of events and p is the probability of the shot missing
λ = 100 x 0.05 = 5
Define X such that X = Number of misses and X ≅ Poisson (λ = 5)
P [X ≤ 2] = P [X = 0] + P [X = 1] + P [X = 2]
P [X ≤ 2] = e⁻⁵ + e⁻⁵ x 5 + e⁻⁵ x 5²/2!
P [X ≤ 2] = e⁻⁵ [1 + 5 + 5²/2!]
P [X ≤ 2] = e⁻⁵ x 12.25 = 0.082
The required probability that there are at most 2 misses in the first 100 attempts is 0.082
Using the z-distribution, the 95% confidence interval for the proportion is given as follows:
(0.4576, 0.5824).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
The other parameters for the interval are given as follows:
.
The lower and upper bound of the interval, respectively, are given by:
