Answer:
The greatest value is "e"
Step-by-step explanation:
We have the following equations:
a. 1.31 a = f
b. 1.12b=f
c. 1.01c=f
d. 0.98d=f
e. 0.31e =f
Then solving for "a", "b", "c", "d" and "e" we have:
a. a = f /1.31
b. b=f/1.12
c. c=f /1.01
d. d=f / 0.98
e. e=f / 0.31
Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.
The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.
Error = 1/2(Maximum range - Minimum range) = 1/2(3.2-1.1) = % = 0.0105
If p is the point estimator;
Then,
Minimum range = p - Error
Maximum range = p + Error
Solving one of the two expressions,
0.011 = p - 0.0105 => p = 0.011+0.0105 = 0.0215 = 2.15%
Answer:3600 motorcycles
Step-by-step explanation:
The total ratio is first obtained then the total number of automobiles is obtained from the number of sedans given. From this, the number of motorcycles can be obtained using the ratio of motorcycle multiplied by the total number of automobiles.
Answer:
0.6
Step-by-step explanation:
Given: Mean= $750
Standard deviation= $60
First, lets find out z-score of the interval between $624 and $768.
z score= 
z score= 
∴ z score for $624 is -2.1
Now, finding z score for $768
Z score= 
∴ z score for $768 is 0.3
As per the z score table, the value for -2.1 is 0.0179 and for 0.3 is 0.6179
Now, subtracting the value to get proportion

∴ There are 0.6 proportion of laptops are in the range of $624 and $768
