What can you conclude about 3/5 and 60/100 if you know 3/5 is equivalent to 6/10 and 6/10 is equivalent to 60/100

First we check whether \frac{3}{5} is equivalent to \frac{6}{10}

\frac{3*2}{5*2} = \frac{6}{10}

Both top and bottom are multiplied by 2 to get \frac{6}{10}

So they are equivalent fractions.

Now we check whether \frac{6}{10} is equivalent to \frac{60}{100}

\frac{6*10}{10*10} = \frac{60}{100}

Both top and bottom are multiplied by 10 to get \frac{60}{100}

So they are equivalent fractions.

\frac{3}{5} = \frac{6}{10} =\frac{60}{100}

Hence we conclude that they are equivalent fractions.

The head of the Westlane Cultural Center wants to get a sense of how quickly pledges from donors arrive at the center. It takes
Rzqust [24]

Answer:

95.64% probability that pledges are received within 40 days

Step-by-step explanation:

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.

In this problem, we have that:

\mu = 28, \sigma = 7

What is the probability that pledges are received within 40 days

This is the pvalue of Z when X = 40. So

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

Z = \frac{40 - 28}{7}

Z = 1.71

Z = 1.71 has a pvalue of 0.9564

95.64% probability that pledges are received within 40 days
