Answer:
And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
Step-by-step explanation:
For this case we can calculate the % of change with the formula of relative change given by:
For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base
And the New value would be 120 who represent the height of the oak tree
If we replace into the formula we got:
And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
Answer:
1.) yes
2.) no
Step-by-step explanation:
1.) Yes
3x - 2y = 1
3(5) - 2(7) = 1
15 - 14 = 1
1 = 1
2.) No
2x + 8y = 26
2(-3) + 8(-4) = 26
-6 - 32 = 26
-38 ≠ 26
Answer: Yes, the time it takes to run a 100 meter race is a function of the speed you run.
In a function, there is an input and only one corresponding output. In the case of a race time, it depends on your speed.
A person with a slower speed will have a longer race time.
A person with a higher speed will have a shorter race time.
Answer:
The desviation is 8 4/7 or 8.571
Step-by-step explanation:
The conversion for any variable X to a standard z is
![Z=\frac{X-\[Mu]}\\{\[Sigma]}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7BX-%5C%5BMu%5D%7D%5C%5C%7B%5C%5BSigma%5D%7D)
where mu is the mean and sigma de desviation
You can find the value of Z whith the tables of the accumulated probability function. The accumulated probability for the mean is 0.5 .Remenber that the accumlated probability function represent the area at the left of an abscissa. Then
0.5+0.3531=0.8531
Acording to the accumulated probability function table, a Z=1.05 has an area of 0.8531 at its left.
Now it is only solving the equation
![\[Sigma]=\frac{X-\[Mu]}{Z}](https://tex.z-dn.net/?f=%5C%5BSigma%5D%3D%5Cfrac%7BX-%5C%5BMu%5D%7D%7BZ%7D)
σ=
σ=8.571
Answer:
There is no hole
Step-by-step explanation:
2x^2-10x+12 = 2(x-2)(x-3) zeros: x=2 or x=3
x^2-3x-2=0 zeros: x=(3±√17) / 2
the numerator and denominator do not have any common factor
