Answer:
2.149 × 10-5
Step-by-step explanation:
Answer: Option A.
Step-by-step explanation:
For a function f(x) = y, the domain is the set of the possible values of x.
In the image we can see that the graph has two arrows, one pointing to the left and another pointing to the right, this means that the function extends infinitely to both sides.
Then there is no value of x that generates a given problem, then the domain is the set of all real numbers.
The set written in interval notation is:
-∞ < x < ∞
Then the correct option is A.
Answer:
only A is correct
Step-by-step explanation:
To get the equation of the given line, we just have to see if the point given fits into any of the equation
The given point is (15,3)
a) y = 1/5x = 1/5 * 15 = 3
This is correct
b) y = -5(-75) = -375; this is not correct
c) y = 3x
y = 3(15) = 45
This is not correct
d) y = 15x
y = 15(15) = 225
This is incorrect
e) y = -1/5x
y = -1/5 * 15 = -3
This is incorrect
f) y = 5x
y = 5(15) = 75
This is also incorrect
Finding the mean is you have to add it all up:
49+55+52+46+47+42+38= 328
The divide it by the amount of numbers so, 329/7= 47.
Subtract 47 from every number then, but even if you get a negative number you gotta keep it a positive so just ignore it if you get a negative answer when subtracting, once you do that you would add up those answers you got so;
2+8+5+1+0+5+9= 30
Then divide it again, 30/7
Which then you get the M.A.D which is 4.3, rounded to the nearest ten.

Step-by-step explanation:</h3>
There are 2 units of green and 5 units of "pink," so the ratio is ...
... green/pink = 2/5
