Answer:
(820 ; 980)
Step-by-step explanation:
Given :
Sample size, n = 80
Number of bilingual from sample = 36
Sample proportion, phat = x / n = 36 / 80 = 0.45
Margin of Error = 4% = 0.04
Interval = sample proportion ± margin of error
0.45 ± 0.04
(0.41 ; 0.49)
(0.41 * 2000 ; 0.49 * 2000)
(820 ; 980)
Hello :
x the smaller number
x+2x =44
3x ==44
x=44/3
It would be 12 because if you divide 9 by 3/4 also known as .75 (by dividing 3 over 4) you get 9. In the picture is an example of what the dividend divisor and quotient are. Hope this helped! If not, you can ask me
Answer:
One burger is $35 and one taco is $43
Step-by-step explanation:
First you substitute:
4b + 3t = 269 => t = 269/3 - 4/3b
5b + 4t = 347 => b = 35
t = 269/3 - 4/3b
t = 269/3 - 140/3
t = 43
