List 5 numbers that have 3, 5, and 7 as prime factors.
saw5 [17]

You can simply multiply all the combinations of 3,5, and 7 in pairs:

1) 3 * 5 = 15

2) 3 * 7 = 21

3) 5 * 7 = 35

Don't forget the numbers multiplied to itself:

4) 3 * 3 = 9

5) 5 * 5 = 25

6) 7 * 7 = 49

A random sample of 625 10-ounce cans of fruit nectar is drawn from among all cans produced in a run. Prior experience has shown
diamong [38]

Answer:

10.57% probability that the mean contents of the 625 sample cans is less than 9.995 ounces.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}.

Normal probability distribution

Problems of normally distributed samples can be 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.

In this problem, we have that:

\mu = 10, \sigma = 0.1, n = 625, s = \frac{0.1}{\sqrt{625}} = 0.004

What is the probability that the mean contents of the 625 sample cans is less than 9.995 ounces?

This is the pvalue of Z when X = 9.995. So

Z = \frac{X - \mu}{s}

Z = \frac{9.995 - 10}{0.004}

Z = -1.25

Z = -1.25 has a pvalue of 0.1057

So there is a 10.57% probability that the mean contents of the 625 sample cans is less than 9.995 ounces.

A variable that is manipulated by an experimenter to explore its relationship to other variables is a(n) _____ variable.
LuckyWell [14K]

Answer:

Independent variable

Step-by-step explanation:

Independent variable :

An independent variable is a variable that speaks to an amount that is being controlled in a trial. A needy variable speaks to an amount whose worth relies upon those controls.  

It is the variable in a equation that may have its worth unreservedly picked without thinking about estimations of some other variable.

For example :

In equation y=5x+3, x is an independent variable
