Answer:
0.3902
Step-by-step explanation:
The question meets the criteria for the calculation of the confidence interval of a one sample proportion ;
Sample size, n = 27
Number of students with faster reaction time = 14
Phat = x / n = 14 / 27 = 0.6296
The confidence interval is calculated thus :
C. I = Phat ± Zcritical * √[p(1 - p)/n]
Zcritical at 99% = 2.576
C. I = 0.6296 ± 2.576 * √[0.6296(0.3704)/27]
C.I = 0.6296 ± 0.2394042
The lower boundary of C.I = 0.6296 - 0.2394042
Lower boundary = 0.3902
So,
1st year: 3
2nd year: 4(first year), which is 12
3rd year: 6(first year), which is 18
The sum of the 1st, 2nd, and 3rd years is 3 + 12 + 18 = 33
Now, multiply 33 by the price at which Mr. Jackson sold each computer ($185).
We get $6105. Mr. Jackson's gross profit was $6105.
Answer:
It was the The Large Cardinal Project.
Step-by-step explanation:
They used this form of math to calculate the precise place the bomb would land, which was the town where the dictator lived
In order to solve this equation, let's write it out in number form:
-3 - x = -10
In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the -3 by adding 3 to both sides:
-3 + 3 - x = -10 +3
-x = -7
Because there are negatives on both sides, you can simply cancel them out:
x = 7
