Answer:
Total member = a+b+c+d+e+f+g=5+4+2+0+5+0+4=20 member
Step-by-step explanation:
Let suppose the attached histogram
a) Total members whose weight 110 = 5
b) Total members whose weight 120 = 4
c) Total members whose weight 130 = 2
d) Total members whose weight 140 = 0
e) Total members whose weight 150 = 5
f) Total members whose weight 160 = 0
g) Total members whose weight 170 = 4
Total member = a+b+c+d+e+f+g=5+4+2+0+5+0+4=20 member
A histogram is a statistical graphical representation of data with the help of bars with different heights.
Answer:
Approximately 68%.
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 = 1, standard deviation = 0.05.
Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.
0.95 = 1 - 0.05
1.05 = 1 + 0.05
So within 1 standard deviation of the mean, which by the Empirical Rule, is approximately 68% of values.
14 11/18
I got this answer by doing 30 1/9 + 4 1/3= 34 4/9
Now I subtracted 34 4/9 by 19 5/6 to get the answer 14 11/18
TIP: When adding/subtracting/multiplying/dividing mixed numbers change them to an improper fraction first by multiplying the denominator and the whole number then adding the numerator
