Scores on an English test are normally distributed with a mean of 31.5 and a standard deviation of 7.3. Find the score that sepa
vladimir1956 [14]

If X is a random variable representing test scores, then the 41st percentile is the score x such that P(X\le x)=0.41. Transform X to the random variable Z that follows the standard normal distribution via X=31.5+7.3Z:

P(X\le x)=P\left(\dfrac{X-31.5}{7.3}\le\dfrac{x-31.5}{7.3}\right)=P\left(Z\le\dfrac{x-31.5}{7.3}\right)=0.41

The z-score for the 41st percentile is about -0.2275, so

\dfrac{x-31.5}{7.3}\approx-0.2275\implies\boxed{x\approx29.8}

A garden hose emits 9 quarts of water in 6 seconds how much did the water emit in 10seconds
jarptica [38.1K]

Answer:

In 10 seconds, the garden hose will emit 15 quarts of water.  

Step-by-step explanation:

The amount of water emitted by the garden hose over time can be expressed as a ratio:  9/6, or 9 quarts of water for every 6 seconds of time.  We can then simplify this ratio to 3/2, or 3 quarts of water for every 2 seconds of time.  Since the ratio will remain constant, or the same, over time, we can set up an equivalent ratio, or fraction to find the amount of water emitted in 10 seconds:  3/2 = x/10.  We look at the denominators and see that 2 x 5 = 10.  In order to make the ratios equivalent, we would also multiply the numerator by 5:  3 x 5 = 15, which gives us the amount of water emitted in 10 seconds.
