Answer:
The order of the values from greatest to least are as
Step-by-step explanation:
Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.
So,-11 > -13 > -21
Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is
Answer:
83 1/3 %
Step-by-step explanation:
Take the number of black kittens over the total
5/6
Change to a decimal
.833333
Multiply by 100
83.33333%
.33333 repeating is 1/3
83 1/3 %
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:
0.68
Step-by-step explanation:
Given :
Mean = 67
Standard deviation = 17
Probability that X is between 50 and 84
According to the empirical rule :
1 standard deviation from the mean = 68%
2 standard deviations from the mean = 95%
3 standard deviations from the mean = 99.7%
Evaluating the number of standard deviations from the mean:
50 = 67 - 17 = 1 standard deviation
84 = 67 + 17 = 1 standard deviation
Hence ;
50 < X < 84 is 1 standard deviation from the mean which is 68%
Hence, Probability that x is between 50 and 84 is 0.68
