I think the answer to this question is 10% but I don’t know if it’s right
Answer:
Step-by-step explanation:
Given that the Acme Company manufactures widgets, which have a mean of 60 ounces and a standard deviation of 7 ounces
We know that 95% of the area lie between -2 and 2 std deviations from the mean.
i.e. Probability for lying in the middle of 95%
Z score 
Between 46 and 74 oz.
b) Between 12 and 57
convert into Z score

P(-6.86<z<-0.43)
=0.5-0.1664=0.3336
c) X<30 gives Z<-4.83
i.e. P(X<30) =0.00
5 : 7
Marbles : Stones
35/5 = 7
So stones
= 7 * 7
49
=35 : 49
Answer: I'm just answering so if only one person answers then u can give the other person brainliest.

The area is 7 units squared.
3-1 = 2
5--2 = 7
2x7 = 14
14/2 = 7
