Answer:
1,000,000
Step-by-step explanation:
10^3*10^3
1,2,3,4 are the domain. The x column is always the domain.
You can't, the K cancels itself out. There is no solution to this
Answer:
![P(p>0.43) = 0.0436](https://tex.z-dn.net/?f=P%28p%3E0.43%29%20%3D%200.0436)
Step-by-step explanation:
Given
-- proportion of baseball players
--- selected sample
Required
Determine P(p>43%)
First, calculate the z score using:
![Z = \frac{\^{p}-p}{\sqrt{\frac{p(1-p)}{n}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B%5C%5E%7Bp%7D-p%7D%7B%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D)
This gives:
![Z = \frac{48\%-40\%}{\sqrt{\frac{40\% *(1 - 40\%)}{781}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B48%5C%25-40%5C%25%7D%7B%5Csqrt%7B%5Cfrac%7B40%5C%25%20%2A%281%20-%2040%5C%25%29%7D%7B781%7D%7D%7D)
Convert % to decimal
![Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *(1 - 0.40)}{781}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.43-0.40%7D%7B%5Csqrt%7B%5Cfrac%7B0.40%20%2A%281%20-%200.40%29%7D%7B781%7D%7D%7D)
![Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *0.60}{781}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.43-0.40%7D%7B%5Csqrt%7B%5Cfrac%7B0.40%20%2A0.60%7D%7B781%7D%7D%7D)
![Z = \frac{0.43-0.40}{\sqrt{\frac{0.24}{781}}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.43-0.40%7D%7B%5Csqrt%7B%5Cfrac%7B0.24%7D%7B781%7D%7D%7D)
![Z = \frac{0.03}{\sqrt{0.00030729833}}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.03%7D%7B%5Csqrt%7B0.00030729833%7D%7D)
![Z = \frac{0.03}{0.01752992669}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7B0.03%7D%7B0.01752992669%7D)
![Z = 1.71](https://tex.z-dn.net/?f=Z%20%3D%201.71)
So:
![P(p>0.43) = P(Z>1.71)](https://tex.z-dn.net/?f=P%28p%3E0.43%29%20%3D%20P%28Z%3E1.71%29)
![P(p>0.43) = 1 - P(Z](https://tex.z-dn.net/?f=P%28p%3E0.43%29%20%3D%201%20-%20P%28Z%3C1.71%29)
![P(p>0.43) = 1 - 0.9564](https://tex.z-dn.net/?f=P%28p%3E0.43%29%20%3D%201%20-%200.9564)
![P(p>0.43) = 0.0436](https://tex.z-dn.net/?f=P%28p%3E0.43%29%20%3D%200.0436)
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Or just subtract
9.884 * 10^6 - 1.009 * 10^7=
− 2.05999999 × 10^5
Rounded up is:
− 2.06× 10^5
