Answer:
Domain: [-5, 1)
Range: (5, 1]
General Formulas and Concepts:
<u>Algebra I</u>
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
According to the graph, our x-values span from -5 to 1. Since -5 is a closed dot, it is inclusive in the domain. Since -1 is an open dot, it is exclusive in the domain:
[-5, 1)
According to the graph, our x-values span from -5 to 1. Since -5 is an open dot, it is exclusive in the range. Since 1 is a closed dot dot, it is exclusive in the range:
(5, 1]
Answer: 
Step-by-step explanation:
Given : Significance level : 
Critical value : 
Sample size : n=1305
The proportion of tenth graders read above the eighth grade level. =
The confidence interval for population proportion is given by :-
Hence, the 99% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level is (0.771,0.829) .
85% will be correct i feel like
She is wrong. The way we know this is by this. If you are going 70 mph for 30 miles than you have to spilt the mph sign in half so 35 miles in 30 minutes.The you subtract 4 from each getting 31 miles in 26 minuets. Therefore Lethna is wrong.
Answer:
Probability = 0.2865
Step-by-step explanation:
There are 65 accidents per year. We know that there are 52 weeks in a year, so let us determine the number of accidents in a week.
65/52 = 1.25 accidents in a week
If we use Poisson distribution, remember that X = the number of occurrences of a particular event in an interval of time or space. In this case X = 0, as we need to find the probability of there being no accidents. Our set up...
P(X = x) = λ^x * e^-λ / x!,
1 week => λ = 1.25,
P(X = 0) = 1.25^0 * e^-1.25/0!
= 1 * e^-1.25
= 1/e^1.25 ≈ 0.2865
