Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
The correct option is
d) (179.20, 212.716)
Step-by-step explanation:
We have out of a random sample of 1000, 345 carried more than a bag
Therefore in the question our X = 345 passengers carry more than a piece of luggage
n = 1000
Therefore the probability of a passenger carrying more than one luggage = 345/1000 = 0.345
The confidence interval estimator of p is given by
where p' = 0.345 = probability of desired outcome
n = 1000 = Population size
z at 95 % = Confidence interval estimate, the value is sought from the distribution table as z value is 1.96 at 95 % confidence level
We have 
which gives
0.3745 or 0.3155
Which gives the range of confidential interval estimate as
212.695 to 179.224 which is equivalent to
d) (179.20, 212.716).
Answer:
3
Step-by-step explanation:
because there are only three pictures
6(2x-3)+4 = 16-(-18)
(6)(2x)+(6)(-3)+4 = 16+18
12+ -18+4 = 16+18
(12x)+(-18+4) = (16+18)
12x+ -14 = 34
12x-14 = 34
12x-14+14 = 34+14
12x = 48
12x/12 = 48/12
x = 4
Answer: 171 km³ per year.
_________________________________
{ <u><em>Note</em></u>: This is the answer for which you seek. However, this is the "amount" lost in the first year. For the second year, you would calculate 0.006% of
"171 km³ " to find out how the amount of ice lost in the second year.}.

Explanation:
__________________________________________________________
0.006% = 0.006/ 100 = 0.00006 ;
0.00006 * 2,850,000 km³ = 171 km³ per year.
