Answer:
Margin of Error = 1.96 
7.75 = 15.19
Step-by-step explanation:
i) Margin of Error of a population with a standard deviation of 7.75?
ii) Let us assume a two tailed test with a 95% confidence interval
iii) 
iv) therefore Margin of Error = 1.96 7.75 = 15.19
Answer:
15 < x < 31
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
23 - 8 < x < 23 + 8
15 < x < 31
Answer:
y + 3 = 4(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = 4 and (a, b) = (- 1, - 3), hence
y + 3 = 4(x + 1) ← in point- slope form
You would convert one of the units to the other, then find the ratio between them when they are the same.
Example: 2 inches and 10 centimeters
1 inch = 2.54 cm
2 x 2.54 = 5.08
10 / 5.08 = 1.969
10 cm is 1.969 times longer than 2 inches.
