Answer:
21
Step-by-step explanation:
product of 3 number= 1197
1st number= 3
2nd number= 19
3rd number= let,X
Now,
3*19*X= 1197
or, 57*X= 1197
or, X= 1197/57
X= 21
Answer:
Looks good to me! :)
Step-by-step explanation: Hope you have a great rest of your day!
Step-by-step explanation:
First, find the expected value.
μ = 0 (0.28) + 1 (0.37) + 2 (0.22) + 3 (0.08) + 4 (0.05)
μ = 1.25
Now find the standard deviation.
σ² = (0−1.25)² (0.28) + (1−1.25)² (0.37) + (2−1.25)² (0.22) + (3−1.25)² (0.08) + (4−1.25)² (0.05)
σ² = 1.2075
σ = 1.099
If we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.099 from the mean.
Answer:
It'd descend 25ft per second
Step-by-step explanation:
500 divided by 20
Answer:
well when you think about it standard form is a way of writing down very large or very small numbers easily for example 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ and there are so many x and y in the problem I am pretty sure the answer will be D None of the above
