Answer:
5
Step-by-step explanation:
We can subtract both sides of the equation by 3, getting 3 + p - 3 = 8 - 3.
Then we can evaluate, getting p = 8 - 3 = 5.
Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
Answer:
x = 0, x = 0.5 or 1/2 The points on the graph are ( -1/2 or -0.5,0 ) and ( 1,0 )
Step-by-step explanation:
2x^2-x-1 = -1
2x^2-x = 0
x(2x-1) = 0
x=0
x=0.5 or 1/2
Answer:
1. 6, 4. 27s, 6. 11mn/ 7. 12(3x+2), 8. 3(2+x), 11. 2(x-2)
Step-by-step explanation:
the GCF is the highest factor that can go into each monomial, 27s factors are 27 and 1 as well as s, 57st factors are 26 and 2 as well as 57 and 1, with s and t. the highest factor is 27 with s, or 27s. the same thing applies with factoring monomias just take out the GCF and multiply it by what's left. 6 has factors of 6 and 1 as well as 2 and 3, 3x has factors of 3 and 1 with x take the common 3 out and your left with 3(2+1x) or 3(2+x).
Answer:
Uhh I think in between t and v?
