<em>Complementary </em>angles are two angles that add up to a <em>right </em>angle, or 90°.
If ∠A and ∠B are complementary, that means that m∠A + m∠B = 90°. Plugging in the given values for m∠A and m∠B, we have
(2x-29) + (x + 23) = 90
Which we can use to solve for x:
2x - 29 + x + 23 = 90
(2x + x) + (-29 + 23) = 90
3x - 6 = 90
3x = 96
x = 32
Since we already know m∠B = (x + 23)°, we can substitute x to find that m∠B = (32 + 23)° = 55°
Answer:
Think about it
Step-by-step explanation:
If you made $20 in 2 hrs you made $10 per hour
To find out how much you make per certain number of hrs multiply $10 by the number of hours
The equation is y = 10x + 0 <-- this is also answer to number 4
10x is the constant of proportionality I think.
Answer:
A Poisson distribution, with λ=5.3
![P(x) = \frac{\lambda^{x} *e^{-\lambda}}{x!}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20%5Cfrac%7B%5Clambda%5E%7Bx%7D%20%2Ae%5E%7B-%5Clambda%7D%7D%7Bx%21%7D)
Step-by-step explanation:
For this type of random variables, a Poisson distribution is the most adecuate.
If the number of occurrences in ten minutes is 5.3, we can define the parameter λ=5.3 and the probability function as:
![P(x) = \frac{\lambda^{x} *e^{-\lambda}}{x!} =\frac{5.3^{x} *e^{-5.3}}{x!} \approx\frac{0.005*5.3^{x}}{x!}](https://tex.z-dn.net/?f=P%28x%29%20%3D%20%5Cfrac%7B%5Clambda%5E%7Bx%7D%20%2Ae%5E%7B-%5Clambda%7D%7D%7Bx%21%7D%20%3D%5Cfrac%7B5.3%5E%7Bx%7D%20%2Ae%5E%7B-5.3%7D%7D%7Bx%21%7D%20%5Capprox%5Cfrac%7B0.005%2A5.3%5E%7Bx%7D%7D%7Bx%21%7D)
