Answer:
X = - 84
Step-by-step explanation:
Answer:
the confidence interval for the true weight of the specimen is;
4.1593 ≤ μ ≤ 4.1611
Step-by-step explanation:
We are given;
Standard deviation; σ = 0.001
Sample size; n = 8
Average weight; x¯ = 4.1602
We are given a 99% confidence interval and the z-value at this interval is 2.576
Formula for confidence interval is;
CI = x¯ ± (zσ/√n)
Plugging in the relevant values, we have;
CI = 4.1602 ± (2.576 × 0.001/√8)
CI = 4.1602 ± 0.000911
CI = (4.1602 - 0.000911), (4.1602 + 0.000911)
CI ≈ (4.1593, 4.1611)
Thus, the confidence interval for the true weight will be expressed as;
4.1593 ≤ μ ≤ 4.1611
Where μ represents the true weight
Answer: 121.836
Step-by-step explanation: So the first thing you need to do is:
31.24
x3.90 you need to put the zero there because the decimal points would need to match up.
_____
Once you do that just put the decimal down. Like this:
31.24
x3.90
____ Once you do that just ignore the decimal and multiply.
.
Once you have finished, the answer should be 121.836.
Hope I Helped!
:)
The answer is 16 because 16•5=80 and then 80-9=71 yk?
Hello there!
The correct answer is C. 225.
Hope This Helps You!
