Answer:
32 divided by 4 would be 8
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) y - 6 = -12(x + 4)
y = -12x - 48 + 6 = -12x - 42
Answer is (C)
2) y + 4 = -5(x - 3)
Only the point (3,-4) would be located on this line
Answer is (C)
It seems as though when the x value is multiplied by 7, you result in the y values (ex. 1*7 = 7). So you could say y = 7x.
Answer:
(b)
We can use an estimatior for the population proportion as since we don't know previous info. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since the confidence level is 99%, our significance level would be given by and . And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
