Write 6X10X10X10X10 with an exponent.
1 answer:
Answer:
6 × 10 × 10 ×10 × 10 =
Step-by-step explanation:
The exponent of any number shows that how many times that number can be used in multiplication. It is the power raised to any number which show the number of times that number is raised by.
6 × 10 × 10 ×10 × 10
Here 10 is multiplied 4 times, therefore the exponent of 10 is 4.
∴ 6 × 10 × 10 ×10 × 10 =

Answer:
Under 99% confidence level we can say that mean speed of the new chips is greater than that of the old chips
Step-by-step explanation:
: Mean speed of the new chip is the same as the old chip
: Mean speed of the new chip is greater than the old chip
to calculate the z-statistic we can use the formula:
z=
if we put the numbers then
z= =4.8171
The probability of this z-statistic is < 0.001 Therefore Under 99% confidence level we can say that mean speed of the new chips is greater than that of the old chips
Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A () = 0.33
Variance of activity B () = 0.67
Variance of activity C () = 0.33
Variance of activity D () = 0.17
Thus the standard deviation on the critical path () =
