Answer:
3,702,856
Step-by-step explanation:
add the three million and then look at the second number you need to add to it and it is seven hundred and two thousand so it should be 702 instead of 720.
What we have so far:
Kinetic energy = 0. The reason behind that is because the beam is not moving at a height of 40m.
Gavity, g = 9.8m/s²
Height = 40m
Potential energy = mgh; this is equal to 0 because m, stands for mass and in this problem, we do not have a value for the mass of the beam. Hence, 0 x 9.8m/s² x 40m = 0. Potential energy = 0.
Solution:
We will use the equation of Total energy:
TE = potential energy + kinetic energy
TE = 0 + 0
∴ TE = 0
The answer is: Assuming no air resistance, the total energy of the beam as it hits the ground is 0.
Answer:
5/51 or 0.098
Step-by-step explanation:
Yes, there is statistical evidence that the drug is effective in reducing infarct size because p-value is less than the significance value.
<h3>
How to find hypothetical Evidence?</h3>
Let us first define the hypotheses;
Null Hypothesis; H₀: µ = 25
Alternative Hypothesis; H₁: µ < 25
Standard Deviation; σ = 10
Sample mean; x' = 16
Sample size; n = 8
z-score is;
z = (16 - 25)/(10/√8)
z = -2.55
From online z-score table, the p-value is 0.005
Since p-value is less than the significance value, then we reject the null hypothesis and conclude that the drug is effective in reducing infarct size.
