Answer:
The slope of the line that joins the points is negative.
i.e m = -6/5
Step-by-step explanation:
Taking two points from the graph to determine the slope
Finding the slope between (-3, 4),(2, -2)
'
Therefore, the slope of the line that joins the points is negative.
i.e m = -6/5
Answer:
72°
Step-by-step explanation:
Find the image of the question attached
The sum of angle in a triangle is 180°
Hence:
15x+24x+21x = 180°
60x =180
x =180/60
x= 3
Get the largest angle
The largest angle out of the angles is 24x
24x =24(3)
24(3) =72°
Hence the measure of the largest angle is 72°
Answer:
So the answer for this case would be n=220 rounded up to the nearest integer
Step-by-step explanation:
Information given
represent the population deviation
represent the margin of error
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =5 and we are interested in order to find the value of n, if we solve n from equation (4) we got:
(b)
The critical value for 90% of confidence interval now can be founded using the normal distribution. The significance level is and the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=220 rounded up to the nearest integer
