Answer:

y = 2x

Step-by-step explanation:

(Slope is 2)

Point Slope form:

y - y1 = m(x - x1)

Put in the points and solve:

y - 2 = 2(x - 1)

y -2 = 2x - 2

 +2          +2

y = 2x

Answer:

y=2x+0

Step-by-step explanation:

so 1,2 can be used in

m=y2-y1/x2-x1

the other coordinates are (-1,-2)

m=-2-2/-1-1

that would be -4/-2, which simplified is 2

m=2

so that would leave the y intercept, which is where the line crosses 0

that would be at (0,0)

another equation would be y+2=2(x+1)

I used the coordinates (-1,-2)

A factory dumps an average of 2.43 tons of pollutants into a river every week. if the standard deviation is 0.88 tons, what is t
vovikov84 [41]
25.8%  
First, determine how many standard deviations from the norm that 3 tons are. So:
 (3 - 2.43) / 0.88 = 0.57/0.88 = 0.647727273  
So 3 tons would be 0.647727273 deviations from the norm. Now using a standard normal table, lookup the value 0.65 (the table I'm using has z-values to only 2 decimal places, so I rounded the z-value I got from 0.647727273 to 0.65). The value I got is 0.24215. Now this value is the probability of getting a value between the mean and the z-score. What I want is the probability of getting that z-score and anything higher. So subtract the value from 0.5, so 0.5 - 0.24215 = 0.25785 = 25.785%  
So the probability that more than 3 tons will be dumped in a week is 25.8%

I need help with the equation.
natulia [17]

Answer:

(x - 3)² + (y + 9)² = 25

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

Given area = 25π , that is

πr² = 25π ( divide both sides by π )

r² = 25 ( take the square root of both sides )

r = \sqrt{25} = 5

With centre (h, k) = (3, - 9 ) and r = 5 , then

(x - 3)² + (y - (- 9) )² = 5² , that is

(x - 3)² + (y + 9)² = 25
