Sample size, N = 3450
Point estimate of republican, p = 1789/3450 = 0.5186 = 51.86%
Z = 1.96 at 95% confidence level
Now,
True percentage of republican residing in California = p +/- Z*Sqrt [p91-p)/N] = 0.5186+/- 1.96* Sqrt [0.5186(1-0.5186)/3450] = 0.5186+/-0.017 = (0.5016,0.5356) = (50.16%,53.56%).
Answer: v = - 9
Step-by-step explanation:
Since two points on the line are given, we use formula for slope.
Let (a,b) and (c,d) be two points on the line, the slope of the line is given by
m=
.
Hence, using this we have
-4=
Thus, we have
-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9
Answer:
1.7x3.9=6.63 so each shaded area is 6.63 then add
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
60+24x=28+28x
Subtract 24x from both sides:
60=28+4x
Subtract 28 from both sides:
32=4x
Divide both sides by 4:
8=x
Hope this helps!
The answer is C because multiply and divide by (x+2)(2x+3)
= ( (x+9)(x+2) + (x+4)(2x+3) ) ( (x+2)(2x+3))
= ( (x^2+11x+18) + (2x^2+11x+12) ) / ( 2x^2+7x+6)
= (3x^2+22x+30) / (2x^2+7x+6)
