Answer:to divide you have to have the same number for the bottom number so you will divide 2\6 by 5\6a and you will probably get a answer with a graphing calculator i hope this helps
Step-by-step explanation:
Answer:
X=31
Step-by-step explanation:
-21+31=10
31 - 21 = 10
Solution: 1. The mean is given below:
Where:
is the frequency
is the value
Therefore, the mean = 2.4
2. The mean is given below:
I am not understanding why your teacher 14.3 is wrong. Please check whether the weight of 4 pumpkins is correct or not.
3. We are given that on average 5 passengers will board the bus at each of the 6 stops.
Let x be the number of passengers board the bus at the sixth stop.
Therefore, the average is:
Therefore, 7 passengers need to board the bus at the sixth stop for Leah's prediction to be true.
Function: f(x) = – log(5 – x) + 9
Restriction for the domain of f:
5 – x > 0
x < 5
So the domain of f is
Dom(f) = {x ∈ R: x < 5}
or using the interval notation,
Dom(f) = ]– ∞, 5[.
________
Next, we want to show that for any given y ∈ R, there is always an x ∈ Dom(f) so that
y = f(x)
Once we show that, we can conclude that the range of f is R (all real numbers).
Solving the equation for x:
y = f(x)
y = – log(5 – x) + 9
y – 9 = – log(5 – x)
– (y – 9) = log(5 – x)
9 – y = log(5 – x)
5 – x = 10^(9 – y)
x = 5 – 10^(9 – y)
Since there is not any restriction for y, the range of f is R (all real numbers).
I hope this helps. =)
