The gradient of AB is BC as it is on a straight line
Hope this is correct!!
(-2,5)(1,1)
slope = (y2 - y1) / (x2 - x1)
slope = (1-5) / (1 - (-2) = -4/3
y = mx + b
slope (-4/3)
(1,1)..x = 1 and y = 1
now we sub
1 = -4/3(1) + b
1 = -4/3 + b
1 + 4/3 = b
3/3 + 4/3 = b
7/3 = b
y = -4/3x + 7/3.....(0,T)...x = 0
y = -4/3(0) + 7/3
y = 7/3
check...
(1,1)(0,7/3)
slope = (7/3 - 1) / (0 - 1)
slope = (7/3 - 3/3) / -1
slope = (4/3)/-1 = -4/3
if I did this correctly, I am thinking T = 7/3
Answer: 112
Step-by-step explanation:
Given : Significance level : 
Critical value: 
Margin of error : E = 9%=0.09
The estimated proportion of caret : p =0.38
Now, the formula to find the sample size :-
i.e. 
Hence, the required minimum sample size = 112
Answer:
y = 5/4x-15
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 5/4x+b
Substitute the point into the equation and solve for b
-5 = 5/4(8)+b
-5 = 10+b
Subtract 10 from each side
-5-10 = b
-15 = b
y = 5/4x-15
Answer:
(a-1)²(b-1)²=a²b²+a²-b²+1²=(ab)²+(a-b)²+ 1
