1,800 and 60 I would believe since we're rounding
Answer:
(x - 6)(x - 11)
Step-by-step explanation:
x² - 17x + 66
-11 and -6
x² -11x - 6x + 66
x(x -11) - 6(x -11)
(x - 6) (x - 11)
(x = 6 or x = 11) These are the possibilities of x
Answer:
Shortest distance=|AC|/![\sqrt[2]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B2%7D)
.
Kindly find the attached for the figure
Step-by-step explanation:
This problem can be addressed using right-angled,
Let have right angle triangle with the shortest distance=hypotenuse;
hypotenuse=|AC|
using pythagoras theorem, we have
|AC|^2=|AB|^2+|BC|^2
Let |AB|=|BC|
|AC|^2=2|AB|^2
|AB|=|AC|/
Shortest distance=|AC|/
<span>b. true. the spread of a normal distribution is completely determined by its standard deviation.
A normal distribution is defined by 2 values, its mean and it's standard distribution. The standard distribution determines what the shape of the curve looks like. A small distribution causes the curve to be tall and skinny. A large distribution causes the curve to be short and fat. The overall shape is entirely determine by the standard deviation. The exact location of the peak is determined by the mean. So let's look at the options and see why they're right or wrong.
a. false. the spread of a normal distribution is completely determined by its mean.
* This is exactly wrong. The mean determines where the peak is, the shape is determined by the standard distribution.
b. true. the spread of a normal distribution is completely determined by its standard deviation.
* This is absolutely correct.
c. true. the spread of a normal distribution is completely determined by its median.
* Once again, it's swapping the meaning between mean and standard distribution.
d. false. the spread of a normal distribution is determined by both its mean and standard deviation.
* This is a bit of weasel wording here. But remember, the SHAPE is determined by the standard distribution while the location of the peak is determined by the mean.</span>
