Let's assume length of the room as y
so the width of the room = y - 5
Area
y * (y - 5) = 750
Answer:
x = 4
Step-by-step explanation:
It is stated that f(x) passes through
(-3, 3), (0, 3), (4, 3)
and g(x) passes through
(-4, -3), (0, 0), (4, 3)
Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.
Answer:
WTH IS THAT KINDA QUESTION
Answer:

And we can use the following z score:

And replacing we got using the normal standard distribution table or excel:

C.0.8413
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the records of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:
We select a sample of size n=36, and we want to calculate this probability:

And we can use the following z score:

And replacing we got using the normal standard distribution table or excel:

C.0.8413
Answer:
1:3
Step-by-step explanation:
The total animals is 45 and the cats is 15.
The ratio is 15:45
Simplified, it would be 1:3 because you can divide each side my 15.
Hope this helped!! :)
