Answer:
y = 3x
Step-by-step explanation:
(1 , 3) and (2, 6)
m=(y2-y1)/(x2-x1)
m=(6-3)/(2-1)
m=3/1
m=3
y - y1 = m(x - x1)
y - 3 = 3(x - 1)
y - 3 = 3x - 3
y = 3x
Solution :
Alpha, α = 0.01
The sample proportion is :
= 0.636
Test statistics, 
z = 7.727
The p value = 0.00001
Here we observe that p value is less than α, and so we reject the hypothesis 
.
Therefore, there is sufficient evidence,
8352. Multiply 20880 by 2 then divide by 5.
Answer:
2 1/4
Step-by-step explanation:
Number 1 is incorrect because 1/4 x 9 is 2 1/4 not 1 1/4.
To multiply fractions, multiply directly across. So multiply 1/4 x 9/1 to get 9/4 which converted into a mixed number is 2 1/4.
Answer:
18x + 28 is the perimeter
Step-by-step explanation:
As perimeter is the som of all side
So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4
= 6x+3x+6x+2x+x + 8+6+5+2+3+4
= 18x + 28
