3. The weights of apples in a shipment from Al's Orchards are normally distributed with a mean of 142 grams and a standard devia

tion of 9 grams. The weights of apples in a shipment from Zippy's Orchards are normally distributed with a mean of 165 grams and a standard deviation of 13 grams.
A rotten apple has a mean of 156 grams. Was it more likely to come from Al's or from Zippy's? Use z-scores to explain. Show your work

The z scores corresponding to the mean weight of a rotten apple relative to the apples from either orchard are, respectively,

\dfrac{142-156}9\approx-1.56

\dfrac{165-156}{13}\approx0.69

The mean for the standard normal distribution is 0, which means that z scores closer to 0 represent data points that are more likely to occur. Therefore it's reasonable to believe that rotten apples occur more often in shipments from Zippy's.

What is the equation of a line passing through (-3,7) and having a slip of -1/5
MrRa [10]

Answer:

\large\boxed{D.\ y=-\dfrac{1}{5}x+\dfrac{32}{5}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the slope m = -1/5. Substitute:

y=-\dfrac{1}{5}x+b

Put the coordinates of the given point (-3, 7) to the equation:

7=-\dfrac{1}{5}(-3)+b

7=\dfrac{3}{5}+b            <em>subtract 3/5 from both sides</em>

6\dfrac{2}{5}=b\to b=\dfrac{6\cdot5+2}{5}=\dfrac{32}{5}

2q = 1+5q-2p

-3q=1-2p

-q = 1-2p/3

<span>The complete question includes these choices: A)1 foot B)2 feet C)5 feet D)9 feet The correct answer is B) 2 feet, approx. 24 inches; most standard desks have a height between 28'' to 30''. The answer A is too low, C and D are too much, the perfect answer would be at least 3-4 feet, but as this question proposes only these answers, the nearest estimating value is B)2 feet. </span>
