Answer:
B. 108 calories
Step-by-step explanation:
The mean number of a data set is
Corn chips: 230 calories
Popcorn: 25 calories
Potato chips: 115 calories
Pretzels: 62 calories
Thus,
The sum of all calories 
The number of productrs = 4
The mean number of calories 
Answer:
93.19%
Step-by-step explanation:
We have that the mean (m) is equal to 70.4, the standard deviation (sd) 11.1 and the sample size (n) = 140
They ask us for P (x =69)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd / (n ^ 1/2))
We have all these values, replacing we have:
z = (69 - 70.4) / (11.1 / (140 ^ (1/2)))
z = 1.49
With the normal distribution table (attached), we have that at that value, the probability is:
P (z <1.49) = 0.9319
The probability is 93.19%
2.5 week 3 days = 20 days and 12 hours
2.5•7=17.5 17.5 +3 = 20.5
5 week 3 days = 38 days
5•7=35 35+3= 38 days
Notice that we have common denominator 2, so we can split the denominator to express the function in the form
where
is the slope
is the y-intercept
Look what we have here, a linear function! We know that the domain and range of linear functions is the real numbers.
We can conclude that:
the domain of the function is
all the real numbers
the range of the function
is all the real numbers
Now, to find the inverse of our function, we are going to replace
with
; then, we are going to interchange
and
and solve for
:
The inverse of our linear function, is another linear function, so we can conclude that:
the domain of the inverse function is
all the real numbers
the range of the inverse function
is all the real numbers
