Crime scene investigators could also ask about fingerprints, foot prints, and blood.
Answer:
That makes 21
Whats your question?
What do you need help on?
I took algebra a while ago so I may be able to help you.
Explanation:
t = t₀ / 2
Explanation:
In this exercise we must use Newton's second law
F = m a
a = F / m
now we can use kinematics
as in object part of rest (v₀ = 0)
v =a t₀
t₀ = v / a
these results are with the first experiment
now repeat the experiment, but F = 2F₀
a = 2F₀ / m = 2 a₀
v = 2 a₀ t
t = v / 2a₀
t = t₀ / 2
Explanation:
We are given:
sample size= n = 45
sample mean = x = 61,300
sample standard deviation =18,246
Since the population standard deviation is not known we will use t distribution to find the confidence interval.
Confidence interval = 99%
Degrees of freedom= n - 1 = 45 – 1 = 44
Critical t value = 2.692
The 99% confidence interval will be:
Thus, the 99% confidence interval for the population mean is:
53978 to 68622
