Suppose that a student needs to buy 6 books for her history course. the number of books that she will be able to find used is a

binomial random variable x with n = 6 and p = 0.30. in other words, the probability that she will find any given book used is 0.30, and is independent from one book to the next. what is the probability that she will find more than 2 used books?0.6760.2560.3240.744

An electronics company just finished designing a new tablet computer and is interested in estimating its battery-life. A random
Alika [10]

Answer:

6 \pm 2.861(0.3354)

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 20 - 1 = 19

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.99}{2} = 0.995. So we have T = 2.861.

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 2.861\frac{1.5}{\sqrt{20}} = 2.861(0.3354)

In which s is the standard deviation of the sample and n is the size of the sample.

The format of the confidence interval is:

S_{M} \pm M

In which S_{M} is the sample mean

So

6 \pm 2.861(0.3354)

PLZ ANSWER FAST I HAVE TIME LIMIT Find exact values for all the solutions to the equation tan theta= - sqrt3/3 for, -2<img src="
galina1969 [7]

Answer:

Well, these simulation are based on the statistics (lognormal-distributed PE, χ²-distributed s²). If you believe that only the ‘gold-standard’ of subject-simulations are valid, we can misuse the function sampleN.scABEL.sdsims() – only for the 3- and 4-period full replicates and the partial replicate:

# define a reg_const where all scaling conditions are ‘switched off’

abe    <- reg_const("USER", r_const = NA, CVswitch = Inf,

                   CVcap = Inf, pe_constr = FALSE)

CV     <- 0.4

 2x2x4  0.05  0.4  0.4   0.95    0.8   1.25          34       0.819161          0.8

Since the sample sizes obtained by all simulations match the exact method, we can be confident that it is correct. As usual with a higher number of simulations power gets closer to the exact value.

Answer:

6 square units

Step-by-step explanation:

In oder to do this, you need graph paper to make it easier and then mark your graph paper with the quadrants.

I got 3 unites for the height and 4 units for the base

4 x 3 = 12 square units

however the formula for a triangle is Ab/2

so divide 12/2 = 6

So its 6 square units
