Answer:

STEP 1. Locate the y-intercept on the graph

- Locate 5 on the y-axis

STEP 2. Use [Rise/Run] method to graph the slope

- Since the slope is 2, [Rise/Run] will be [2/1] which means 2 unit vertically (y), 1 unit horizontally (x)

----------------------

and boom!! That's all!!

EXTRA, this is the graph for y=2x+5

Hope this helps!! :)

Please let me know if you have any question

Answer:

Step-by-step explanation:

always start with the y-intercept which is ur b in y=mx+b

so u start with 5 on the y-axis

then since the slope is positive 2 u go up two times *FYI: put a 1 under the 2.*

up 2 and go right one time.

it should look like this:

ik this doesnt make sense but hope this helps...

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
