Answer:
y=4/3+19/3
Step-by-step explanation:
When it asks for perpendicular it means your focusing on the slope.
Perpendicular means opposite of the current slope, so flip it and change the sign (-3/4 changes to 4/3). Next you will use the equation (y-y1)=m(x-x1)
y1=the y value given
x1=the x value given
m=your slope
(y-1)=4/3(x+4) Since the x point is minus a negative we get to change the sign to a positive. Next distribute the 4/3 to each term in the parenthesis.
y-1=4/3(x)+4/3(4)
y-1=4/3x+16/3 Now we add the one to both sides.
+1 +1 The one isn't in teh correct format to just add so first imagine it as 1/1. Now to get the bottom to have a 3 like in 16/3 we just multiply the top and bottom by 3.
Now we can add this to the 16/3
We can now put this back into our equation.
y=4/3+19/3
Answer: (0.066,0.116)
Step-by-step explanation:
The confidence interval for proportion is given by :-

Given : The proportion of men have red/green color blindness = 
The proportion of women have red/green color blindness = 
Significance level : 
Critical value : 
Now, the 99% confidence interval for the difference between the color blindness rates of men and women will be:-

Hence, the 99% confidence interval for the difference between the color blindness rates of men and women= (0.066,0.116)
Answer:
5,095,068
Step-by-step explanation:
The equation for this problem is x^y * z where x is the percentage, Y is the number of years, and Z is the original deposit. Multiply 1.9^8 * 30,000 which becomes; 5,095,068.
Whoever has that bank account is going to be very rich.
The answer is X= 25
You just have to divide 125 by 5
