Answer:
weight of a basket of apples
Step-by-step explanation:
because a quantitative variable involves numbers, and the weight of a basket of apples would be a number. all of the other answers describe details of something, but wouldn't involve a specific number.
1.C
12.25= 1hr
1:25= 2hrs
+50 mins
2.A
16.80+16.80= 33.60
16.80= round trip for child
16.80+33.60= 50.40
Answer: The correct option is
(D)
Step-by-step explanation: We are given the following two functions :
![f(x)=3x^2+x-3,\\\\g(x)=x^2-5x+1.](https://tex.z-dn.net/?f=f%28x%29%3D3x%5E2%2Bx-3%2C%5C%5C%5C%5Cg%28x%29%3Dx%5E2-5x%2B1.)
We are to find the expression for f(x) - g(x).
We have
![f(x)-g(x)\\\\=(3x^2+x-3)-(x^2-5x+1)\\\\=3x^2+x-3-x^2+5x-1\\\\=2x^2+6x-4.](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%5C%5C%5C%5C%3D%283x%5E2%2Bx-3%29-%28x%5E2-5x%2B1%29%5C%5C%5C%5C%3D3x%5E2%2Bx-3-x%5E2%2B5x-1%5C%5C%5C%5C%3D2x%5E2%2B6x-4.)
Thus, ![f(x)-g(x)=2x^2+6x-4.](https://tex.z-dn.net/?f=f%28x%29-g%28x%29%3D2x%5E2%2B6x-4.)
Option (D) is CORRECT.
Answer:
an = -6*(1/4)^(n-1)
Step-by-step explanation:
We have that the recursive formula for the given geometric sequence is:
a1 = -6
an = (an-1) * (1/4)
With the above we can assume that:
r = 1/4
following the rule of the explicit formula that is given by:
an = a1 * (r) ^ (n-1)
we substitute and we have:
an = -6 * (1/4) ^ (n-1)
Therefore the explicit formula from the given data would be:
an = -6 * (1/4) ^ (n-1)
If the 2s keep going forever and never end, then the whole thing
is the same as 2/9 .
Every mixed number is bigger than ' 1 ', but 2/9 or 0.2....... is less than ' 1 ',
so there's nothing you can do to it to make it a mixed number.
