slope =(y2-y1)/(x2-x1)
m=(-1-5)/(1--1)
m=-6/2
m=-3
y-y1=m(x-x1) point slope form
y-5 = -3 (x--1)
y-5 = -3 (x+1)
distribute
y-5 = -3x -3
add 5 to each side
y = -3x+2
Choice D
Answer:
H0 : μd = 0
H1 : μd > 0
Step-by-step explanation:
The scenario described above can be compared statistically using a paired test mean as the mean if the two groups are dependent, the two restaurants, Albuquerque and Santa Fe are both restaurant locations of a single restaurant company. Hence, to test the mean difference, we use the paired test statistic. Defined thus `
Null hypothesis ; H0 : μd = 0 and the Alternative hypothesis ; H1 : μd > 0
Third one I think 10,20,30,40
First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>
When you write terms in denominator on numerator, sign of indices changes.
