The mean cost of a five pound bag of shrimp is 40 dollars with a standard deviation of 7 dollars. If a sample of 51 bags of shri

damaskus [11]

Answer:

$P(|\bar{x}-40| > 0.6)=0.5404$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 40 dollars

Standard Deviation, σ = 7 dollars

Sample size,n = 51

We are given that the distribution of cost of shrimp is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling =

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{7}{\sqrt{51}} = 0.9801$

P(sample mean would differ by true mean by more than 0.6)

$P(|\bar{x}-40| > 0.6)\\\Rightarrow = 1-P(39.4$

$P(39.4 \leq x \leq 40.6) \\\\= P(\displaystyle\frac{39.4 - 40}{0.9801} \leq z \leq \displaystyle\frac{40.6-40}{0.9801})\\\\ = P(-0.6121 \leq z \leq 0.6121)\\= P(z \leq 0.6121) - P(z < -0.6121)\\= 0.7298 - 0.2702 =0.4596$

$P(|\bar{x}|-40 > 0.6)\\= 1-0.4596=0.5404$

0.5404 is the required probability.

Please help me with this question

Tanzania [10]

Answer:

∠BFA = 75º

Step-by-step explanation:

First, let's add the three angle degrees provided.

$30+45+60 = 135$

Then, we subtract 135 from 360º, which is all the angles added together.

360º - 135º = 225

Since ∠BFC is 2xº, then we have to divide 225 by 3.

$\frac{225}{3} = 75$

∠BFC is twice the amount of x, so ∠BFC is 75 * 2 = 150º

xº is 75º

To check our answer, we can add all these angles and if they add up to 360º, we are correct.

30 + 45 + 60 + 75 + 150 = 360º :)
