Answer:
2,400 meters
Step-by-step explanation:
4 × 60 sec = 240 meters a minutes
240 meters × 10 minutes = 2,400 meters in 10 minutes
All the choices are in the slope-intercept form where,
y=mx+b
so, the number before the x is the slope. The given slope is -34. We just have to look for the -34 number before the x. So mong the choices, it is the letter a choice that has the slope -34. So the answer is A.
Answer:
v = 9/2 + sqrt(61)/2 or v = 9/2 - sqrt(61)/2
Step-by-step explanation:
Solve for v over the real numbers:
-v^2 + 9 v - 5 = 0
Multiply both sides by -1:
v^2 - 9 v + 5 = 0
Subtract 5 from both sides:
v^2 - 9 v = -5
Add 81/4 to both sides:
v^2 - 9 v + 81/4 = 61/4
Write the left hand side as a square:
(v - 9/2)^2 = 61/4
Take the square root of both sides:
v - 9/2 = sqrt(61)/2 or v - 9/2 = -sqrt(61)/2
Add 9/2 to both sides:
v = 9/2 + sqrt(61)/2 or v - 9/2 = -sqrt(61)/2
Add 9/2 to both sides:
Answer: v = 9/2 + sqrt(61)/2 or v = 9/2 - sqrt(61)/2
Answer:
Confidence interval for the true mean number of reproductions per hour for the bacteria is (10.1,10.5).
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 10.3
Population standard deviation, σ = 2.1
Sample size, n = 728
Alpha, α = 0.01
Confidence interval:
Putting the values, we get,
