Answer:
The interval [2.5, 12.5]
Step-by-step explanation:
<em>Tchebysheff’s Theorem states that for any distribution of probabilities if k ≥ 1, at least </em>
of the data will lie within k standard deviations of the mean.
We need then to find a k greater or equal than 1 such that
or the equivalent equation
Finding the value of k
So, applying Tchebysheff’s Theorem, the manager can assure that the number of employees that can be absent in a given day, lies in the interval
[7.5-2*2.5, 7.5+2*2.5] = [2.5, 12.5]
Answer:
one
Step-by-step explanation:
The maximum number of y intercepts a line can have is one
A line can only cross the y axis one time
A line can only cross the x axis one time
Otherwise it is not linear
Answer:
6°F
Step-by-step explanation:
Given that:
Temperature at 11pm = 48°F
Temperature at 7am = 6° cooler
Temperature at 11am = 48°F
Number of degrees temperature changed from 7am to 11 am
Exact temperature at 7am = (temperature at 11 pm - 6°)
= 48°F - 6°F
= 42°F
Temperature change from 7am to 11am
Temperature at 11 am - temperature at 7am
48°F - 42°F
= 6°F
Hi there.
To start, we have to understand where the ten the place is.
Hint: it's 1 place behind the decimal point.
Now we need to know what numbers behind the tenths place make it round up or down.
If the number behind it is 4 or under, round down.
5 & up, round up.
In this case, 830.248 has 2 numbers behind the decimal, so we have to round those THEN the 2 in the tenths place.
830.25 to 830.3
Your answer is D. 830.3
I know this was lengthy, sorry. Just wanted to explain :p
Answer:
standard deviation
Step-by-step explanation:
The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.
It is denoted by the Greek letter sigma, σ.
Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.
