Answer:
-0.89 (i think)
Step-by-step explanation:
Since the graph seems to be going downwards from the right, it has a negative correlation. And since the data seems to be pretty close together, the correlation must be strong. That narrows the answer down to -0.89
If its wrong then i'm not a smart person, and it's -0.15
6 · e^(4x - 2) = 3
e^(4x - 2) = .5
ln e^(4x - 2) = ln (.5)
4x - 2 = ln (.5)
4x = ln (.5) + 2
x = (ln (.5) + 2)/4
x = 0.3267
x ≈ 0.327
Answer: B
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
- The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share.
- The "per share" part necessitates further computation when the number of common shares changes in the middle of the year.
- The weighting of the per share part depends on how long each share number has been in circulation.
How are basic earnings per share determined?
- Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period.
- Preferred dividends should be removed from the net income because they are not available to common stockholders.
- Net income can also be broken down into "continuing operations" P&L and "total P&L".

Answer:
We have strong evidence that on average, students study less than 150 minutes per night during the school week
Step-by-step explanation:
Normal distribution:
mean μ₀ = 150
Sample:
Sample size n = 272
Sample mean x = 141
Sample standard deviation s = 66
The standard error of the sample mean SE = σ /√n
SE = 66/√272
SE = 66 / 16,49
SE = 4
Test Hypothesis:
Null hypothesis H₀ x = μ₀
Alternative hypothesis Hₐ x < μ₀
z(s) test statistics is:
z(s) = ( x - μ₀ ) / s/√n
z(s) = - 9 /4
z(s) = - 2,25
p-value for that z(s) p-value = 0,0122
Then for α = 0,05 p-value < 0,05
We are in the rejection region we need to reject H₀
