Answer:
The correct answer is: C. The value is a statistic because the 6076 adults in public restrooms are a sample.
Step-by-step explanation:
A sample statistic is a piece of statistical information you get from a part of a population. In this case, 6076 adults in public restrooms.
Now you have recognized the sample, and you infer some measure from this sample. In this case, 23% did not wash their hands before exiting.
D because multiplication is done before addition and subtraction
Answer:
Number of 2 digit number: 10 to 99, 90 numbers. Hence,P(selecting a 2 digit number) = 1/90 = .
Step-by-step explanation:
There are a bunch of p3rverts on this app:/ explanation:
This is a linear function of the form y = mx +b. Moreover we notice in reading the graph that y-intercept is 2 and x-intercept is -3. Thus the 2 coordinates which are given are A(0,2) and B(-3,0)
Now we can find its equation:
1st calculate the slope of AB: (y₂-y₁)/(x₂-x₁) = m
(0-2)/(-3-0)= 2/3 → y = (2/3)x + b
2nd calculate b: Replace x and y by any of either A coordinates or B's
Let's take A for instance: 2= (2/3)(0) +b → b=2 and the final equation:
y= (2/3).x + 2
