Step-by-step explanation:
follow the word problem and solve when needed
I did some research and I think the answer is 255
Step-by-step explanation:
I would suggest that this is cluster sampling.
The teacher is selecting a cluster of the population at random to sample.
This is a method of probabalistic sampling.
The answer is 2304 in the simplified form
Answer:
Step-by-step explanation:
a. Y intercept is where the line crosses the y axis, so for l1 it’s (0,4). Answer is 4.
b. Y intercept for l2 is point (0,2). Answer is 2.
c. l1 gradient is -1/2. Rise/run
So l1 equation is y = -1/2x + 4
l2 gradient is 1.
Equation is y = x + 2
e. x+2= -1/2x + 4
1.5x = 2
x = 1.333...
y = plug into one of the equations value of x. So y = 3.333...
f. 1.33+ 2 = 3.33
-1/2 times 1.33 + 4 = 3.33 (rounded)
