shtirl [24]

Answer:

D)65

Step-by-step explanation:

Striking deviations are any values outside the normal trend of the data. The data set has an interquartile range of 22. If you look at the values that are on the low end you see -5, which is close to the next value of -3 as well as Q1 of -2. On the high end you see the value of 65, which is a long way off to the next value of 37 and even further off from Q3 of 20. A striking deviation would be 65

2) In August, Emily's Clothing Store sold 460 shirts with the ratio of short sleeve to long
aivan3 [116]

Answer:

138

Step-by-step explanation:

We know that there are at least 3 short sleeved shirts and there are at least 7 long sleeved shirts. And we know it's in that ratio. So the best way to start this is to divide 460 by 7+3 to get the single unit amount of both shirts.

46 is the single unit amount. So 46 * 3 will get us our short sleeved shirts:

46 * 3 = 138

To check our answer, we'll take 460-138 and divide that by 7 to see if we get 46:

322/7 = 46

So the answer is correct!
