Hope this helped!!!! :) <3 have a good day ma dude
Answer:
The answer is 126
Step-by-step explanation: You add 495+ 126 and that will get you too 621.
Answer:
- a) about 3.0%
- b) about 7×10^-6
Step-by-step explanation:
These sorts of calculations are best done with a calculator that knows statistics.
a) The z-value of the limit ofv interest is (45,000 -35,551)/(5100) ≈ 1.8743. The empirical rule tells you between 16 and 2.5% of the distribution will lie above a limit that is between 1 and 2 standard deviations. So, our calculator value of 3% is approximately correct.
b) The standard deviation of the sample mean is reduced by a factor of √75 from that of the parent distribution for a sample size of 75. Then the z-value is ...
... (38,000 - 35,441)/(5100/√75) ≈ 2559/588.90 ≈ 4.345
The probability of exceeding this valus is pretty small, about 6.95×10^-6.
You need to post the equations.
I could make a guess and say the equation is:
(x-8)*(x+2) = 0
x^2 -6x -16 = 0
and to have a y-intercept of -48, it should be:
4x^2 -24x -48 = 0
Both lines AB and CD are secant lines beacuse in two points they are touching the circunference. There is a Theorem which says the following
![PB\cdot PA=PD\cdot PC](https://tex.z-dn.net/?f=PB%5Ccdot%20PA%3DPD%5Ccdot%20PC)
Since the distance from the center of the circle to each secant line is the same (5 units), we could assume that the both secant lines are similar. saying:
![PB=PD;\text{ }PA=PC\Rightarrow AB=CD](https://tex.z-dn.net/?f=PB%3DPD%3B%5Ctext%7B%20%7DPA%3DPC%5CRightarrow%20AB%3DCD)
Then the lenght of CD is:
