Step-by-step explanation:
Since the first coordinates are both (0,0) it implies that the line passes through the origin.
The slope of the line is therefore 5/8
The equation:
y-0=5/8(x-0)
y=5/8x
my answer is in the image above
That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as , so
And obviously, you have
It is true that the square of every rational number between 0 and 1 is smaller than the number itself.
But since not all rational numbers are between 0 and 1, the general claim is false.
Answer:
There is evidence to claim that the proportion of drug and alcohol use is higher locally than nationally.
Step-by-step explanation:
Given that a recent drug survey showed an increase in the use of drugs and alcohol among local high school seniors as compared to the national percent.
Let p1 be the proportion of local seniors and p2 national seniors.

Total 100 100 200
p 0.69 0.6 0.645
q 0.31 0.4 0.355

p 0.00391
we find that p value is 0.00391 <0.05
Hence we reject null hypothesis
There is evidence to claim that the proportion of drug and alcohol use is higher locally than nationally.
