Answer:
3.6669
Step-by-step explanation:
Given is a frequency distribution and we are expected to find the mean of the distribution.
Let X be the no of total pets owned and f be the number of adults owning those pets.
Total
x 1 2 3 4 5 6 7
F 248 567 1402 728 419 456 203 4023
x*f 248 1134 4206 2912 2095 2736 1421 14752
Mean 3.666915237
Thus we find the total of all frequencies and then sum of product of x*f.
Mean = sum of f*x/sum of x
Here mean= 3.6669

Answer:
Step-by-step explanation:
video store A : 15 + 1.75m
video store B : 7.5 + 2.25m
15 + 1.75m = 7.5 + 2.25m
15 - 7.5 = 2.25m - 1.75m
7.5 = 0.50m
7.5 / 0.50 = m
15 = m <=== there would have to be 15 movie rentals to make them equal
check...
15 + 1.75m 7.50 + 2.25m
15 + 1.75(15) = 7.50 + 2.25(15) =
41.25 41.25
yep...it checks out
Answer:
all real numbers except ±5.
Step-by-step explanation:
Each function (f(x), g(x)) has a domain that is all real numbers. Their quotient (f(x)/g(x)) must exclude values that make g(x) = 0. The quotient is undefined when the denominator is zero. Those excluded values are x = ±5.
The domain of (f/g)(x) is all real numbers except ±5.
___
Of course you recognize x^2 -25 = 0 has solutions x = ±√25 = ±5. You can get there two ways:
- add 25 and take the square root: x^2=25; x=±√25.
- factor the difference of squares and set the factors to zero: (x-5)(x+5)=0 has solutions x-5=0 and x+5=0, that is, x = ±5.
