Answer:
There is a significant difference between the means of the two population
Step-by-step explanation:
The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.
Range = 140 - 75 = 65
The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.
Range = 183 - 96 = 87
Difference in mean = 104 - 85 = 19
If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence
But by considering the mean difference and the value of range, we can say that
There is significant difference between the means of the two population
Answer:
0.030
Step-by-step explanation:
=> 0.029646
To three dps that there should be only 3 decimals places after rounding off.
So, it becomes
=> 0.030 (Because the digit in ten thousandths place was greater than 5)
Answer:
C. 9
Step-by-step explanation:
Hence, side length of square = 9 feet.
Let x be the number, then 60 = 40% of x & x =60/40%=60/0.4=150
then the number of which 60 represent 40% of it is 150
2) Let x be the time needed to the 16 clerks to finish the job
In one day the 32 clerks complete a portion of 32/22 of the job
In one day the 16 clerks complete a portion of 16/x of the job
So in 1 day===> 32/22 =16/x ==> x=(22*16)/32 = 11 days
7x-5=0
7x=5
x=5/7
Your answer was wrong. When you transpose (shift) the -5 to right side the sign should change and become a positive 5.
I don’t know if that makes sense.
In maths, when you move a number over the equal sign whether it’s to the right or the left of the equal sign the sign infront if the number must change as well.
Example:
2x +4=0
2x= -4
x=-2
