For #19 part A :

By vertical angles and then same side interior angles 3x + 2x = 180
5x = 180
x = 36

For #19 part B:

You are correct with the 35, but you missed the fact that the 105 angle is supplementary with the unknown angle inside the triangle. So:

180 - 105 = 75

Then:

180 = 35 + 75 + x
180 = 110 + x
x = 70

Last question:

Do you know what the symbol means? Text me and tell me and I can answer it for you. :)

Veridian has great answers. I'm only posting this as a supplement to help provide the diagrams showing the various angles, that lead into the equations Veridian uses.

According to a recent survey, the population distribution of number of years of education for self-employed individuals in a c

creativ13 [48]

Answer:

a) X: number of years of education

b) Sample mean = 13.5, Sample standard deviation = 0.4

c) Sample mean = 13.5, Sample standard deviation = 0.2

d) Decrease the sample standard deviation

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 13.5 years

Standard deviation,σ = 2.8 years

a) random variable X

X: number of years of education

Central limit theorem:

If large random samples are drawn from population with mean $\mu$ and standard deviation $\sigma$ , then the distribution of sample mean will be normally distributed with mean $\mu$ and standard deviation $\frac{\sigma}{\sqrt{n}}$

b) mean and the standard for a random sample of size 49

$\mu_{\bar{x}} = \mu = 13.5\\\\\sigma_{\bar{x}} = \dfrac{\sigma}{\sqrt{n}} = \dfrac{2.8}{\sqrt{49}} = 0.4$

c) mean and the standard for a random sample of size 196

$\mu_{\bar{x}} = \mu = 13.5\\\\\sigma_{\bar{x}} = \dfrac{\sigma}{\sqrt{n}} = \dfrac{2.8}{\sqrt{196}} = 0.2$

d) Effect of increasing n

As the sample size increases, the standard error that is the sample standard deviation decreases. Thus, quadrupling sample size will half the standard deviation.

The mean time from prescription drop-off to medicine pickup for a customer served at Heisenberg's Pharmacy is 64 minutes, with a

kari74 [83]

Answer: B. 0.4772

Step-by-step explanation:

Given : The mean time : $\mu=64\text{ minutes}$

Standard deviation : $\sigma=18\text{minutes}$

Let X be the service time of a randomly selected customer.

Assuming a normal distribution, the value of z-score is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x = 64

$z=\dfrac{64-64}{18}=0$

For x = 100

$z=\dfrac{100-64}{18}=2$

The p-value = $P(64$

$P(z$

Hence, the probability that a randomly chosen customer experiences service done between 64 and 100 minutes = 0.4772

Explain how place value could be used to find the difference of $4.23 and $2.75

frozen [14]

I don't know if this is what you mean by your question but can be broken down by place value into 4, 0.20 and 0.03. 2.75 can be broken down into 2, 0.70, and 0.05. Then subtract the same place values from each and you will get 1.48
