Answer:
A. how much of the students time is spent on social media during school hours.
B. By using some kind of selection technique Like Having students draw number from a hat, who ever have the specific numbers will take her survey.
C. The population for Sofies research would be a rate of 5/2. For every 5 people who take the survey only 2 turned it in.
D. She would conclude that 1 out of every 2 or 50 percent of students use social media while doing school work.
Step-by-step explanation:
Answer:
Domain (Basically means the sets of values of x-axis).Hence, the set of values of domain is given by -3<domain<1. Meaning domain lies between values more than -3 and less than 1.
Range (Basically means the sets of values of y-axis). Hence, the set of values of range is given by -1<range<3. Meaning that range lies between values more than -1 and less than 3.
Function basically means the equation of the given circle. We know that equation of circle is given by;
(x-h)^2+ (y-k)^2 = r^2 [where (h, k) is the center of circle and r is the radius of circle]
From the figure,
(h, k)= (-1 ,1) and r= 2.
So, we can conclude that function is given by equation:
(x-(-1))^2 + (y-1)^2 = 2^2
(x+1)^2 + (y-1)^2 = 4.
Anywhere there is a point, is part of the domain. So we see a point at x = -2. x = 0, x = 1, x= 2, x = 3, and x = 4.
So the domain would be
{-2, 0, 1, 2, 3, 4}
Answer choice 1.
E = mgh
m = E/gh
g = E/mh
h = E/mg
The greatest commom factor of 12 and 10 is 2. So, take 2 outside the () so you get. 2(6+5x)
