line f passes from points (85,-45)and (5,-7) line g is parallel to line f what is the slope line of g

nasty-shy [4]

1) The slope is 2
You can find this by finding this rise over run which is essentially counting from one point to the next

2) y intercept is 6
You can tell because when the x axis is at 0, the point is at 6 for the y-axis

3) Now that you have the slope and y intercept the answer is:
Y=2x+6

Suppose that the distribution for total amounts spent by students vacationing for a week in Florida is normally distributed with

Charra [1.4K]

Answer:

96.24% probability that a SRS of 25 students will spend an average of between 600 and 700 dollars

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 $s = \frac{\sigma}{\sqrt{n}}$ .
