Answer:
Between 38.42 and 49.1.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 43.76, standard deviation of 2.67.
Between what two values will approximately 95% of the amounts be?
By the Empirical Rule, within 2 standard deviations of the mean. So
43.76 - 2*2.67 = 38.42
43.76 + 2*2.67 = 49.1
Between 38.42 and 49.1.
Answer:
Step-by-step explanation:
B=2h(a+b) #the numerator goes to the other side, the denominator then just makes it B
B/2h=a+b
2h=a+b/B
2h-a=b/B
2h-a=b(1) #factorise
Answer
a
Step-by-step explanation:
because submarine b has a bigger negative number so its more further down
Need a better picture if u post it again soon I’ll see it and I’ll tell u
