You just have to draw a number line where you put the numbers in order. I brought all fractions to one common denominator which is 20 and plotted them on the number line.

First, you look for a common denominator, which is 20. Since 2 is a multiple of 20, you need to multiply it by 10. Since you multiplied it by 10, you also need to multiply the numerator by 10, giving you 10/20. Remember, you do not multiply the whole number in front of the fraction. You also do the same thing with the first one. Since you need to multiply the denominator by 4, you also need to multiply the numerator by 4, making it 16/20. Now that you have all of the denominator the same, you can now figure out the order from least to greatest by looking only at the numerator. I trust you that you know which ones are greater and which one are lesser.

I hope i helped you. Reply back if you don't understand anything.

Matthew participates in a study that is looking at how confident students at SUNY Albany are. The mean score on the scale is 50.

Answer:

b) 6.68%

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

The mean score on the scale is 50. The distribution has a standard deviation of 10.

This means that $\mu = 50, \sigma = 10$

Matthew scores a 65. What percentage of people could be expected to score the same as Matthew or higher on this scale?

The proportion is 1 subtracted by the p-value of Z when X = 65. So

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

$Z = \frac{65 - 50}{10}$

$Z = 1.5$

$Z = 1.5$ has a p-value of 0.9332.

1 - 0.9332 = 0.0668

0.0668*100% = 6.68%

So the correct answer is given by option b.

what TRANSFORMATIONS take place to the parent graph f(x)= log(x) to achieve the graph g(x)=log(-2x-4)+5?

Leona [35]

The -4 will translate the graph of f(x) 4 units to the right.
Then the -2 before the x will stretch it vertically with factor 2, then reflect it in the y -axis.
Finally the + 5 will translate the graph 5 units vertically upwards
