Answer:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1.5
Standard deviation = 0.1
middle 99.7%
Within 3 standard deviations of the mean, so
1.5 - 3*0.1 = 1.2
1.5 + 3*0.1 = 1.8
So the answer is:
The middle 99.7% of Twinkies weigh between approximately 1.2 and 1.8 ounces.
Answer:
1. 1458
2. 500 or -500
Step-by-step explanation:
1. a4=54, a5=162
r = 162/54 = 3
a7 = a5 × r²
= 162 × 3² = 1458
2.a4=-4, a6=-100
r² = -100/-4 = 25
r = +/- 5
a7 = a6 × r
= -100 × +/- 5
= +/- 500
1·2 = 2
2·2 = 4
4·2 = 8
8·2 = 16
16·2 = 32
32·2 = 64
64·2 = 128
128·2= 256
