Answer:
first one is c becuase of the way i added and then subtactied
second one is a i divide then ad sub and ad it again bye 3
srry if i am wrong
brainlyest would be nice ( ;
Step-by-step explanatnation
We are given the following in the question:
Sample size, n = 200
\hat{p} = 65\% = 0.65
Margin of error =
\pm 6.75\% = \pm 0.0675
\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}
\hat{p}\pm \text{Margin of error}
Putting values:
(0.65 \pm 0.0675)\\=(0.5825,0.7175)
Not always. When something is multiplied by 1, it remains the same number.
Answer:
1
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -15 - -14) / ( -11 - (-10))
= (-15+14) /(-11 + 10)
= -1 / -1
= 1

Answer:
3(m - 3) = 3m - 9
0 = 0
m = infinitely many solutions
Step-by-step explanation:
In the given equation, there is a distribution of the factor of 3 to the expression 'm - 3' on the left side and the expression '3m - 9' on the right. When you distribute the '3', you get: 3m - 9. Since 3m - 9 is equal to 3m - 9, the constants and variables would each cancel out by inverse operations and you would be left with 0 = 0, which indicates an equation with infinitely many solutions.
