Hi there! To find the answer, we need to try out the numbers. 3 * -3 is -9 + 0 is -9. -9 < -8. A is out. 3 * -2 is -6 + -1 = -7. -7 > -8. B works. Score! But wait. 3 * 0 is 0 + 10 is -10. -10 < -8. C is out. 3 * 2 is 6 + -16 is -10. -10 < -8. The answer is B: (-2, -1).
Answer:
std dev = 0.625
Step-by-step explanation:
Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.
We must change std deviation such that
P(X<12) =0.01
Mean would remain the same as 12.8 oz
From normal distribution score we can find
10th percentile is -1.28\
i.e. we must have
Std deviation should be 0.625
Answer:
-6/3x
Step-by-step explanation:
gradient = slope
Rise/run = -6/3x
Answer:
60%
Step-by-step explanation:
40 ft² is 100%
so, 1% = 0.40 ft²
now we need to ask, how often did 1% fit into the 16 ft².
that means
16 / 0.4 = 16 / (4/10) = (16×10)/4 = 160/4 = 40 %
so, the new, smaller area is only 40% of the original area.
and that means, that the area decreased by 100-40 = 60%
The area is 200.96 (or 201 estimated)
