He's 9 years old. :-)
In seven years, he'll be 16, and 16 is two times older than 8 - the age he was last year.
Answer: C
Step-by-step explanation:
Given that the line -3x + y/2 = -3 passes through the points (1, 0) and (0, -6).
First rearrange the equation
-3x + y/2 = -3
Y = 2( 3x - 3 )
Y = 6x - 6 ..... (1)
Also, the slope of points (1, 0) and (0, -6). Will be
M = ( -6 - 0 )/( 0 - 1 )
M = -6/-1
M = 6
Using general linear equation
Y = MX + C
Let Y = 0 and X = 1
0 = 6(1) + C
C = -6
Substitutes C back into the equation
Y = 6x - 6 ...... (2)
The value of b that will cause the system to have infinitely many number of solutions is 6
The margin of error can be calculated with the formula:
ME = z · √(p(1-p)/n)
where:
p = sample proportion
n = sample size
z = z-score
In your case:
p = 90 / 120 = 0.75
ME = 2.58 · √(0.75·0.25/120)
= 0.10
= 10%
The margin of error will be 10%.
1/6 < 1/4 so 1/6 would equal 2/12 and 1/4 would equal 3/12 so which means if you take one from each it would be 5/12 but if you took 2 from the first one it would only be 2/12 which is why you need to read correctly because THE REASON MARK IS CORRECT IS BECAUSE 5/12 IS GREATER THAN 2/12
This is how we solved and make the equation.
Stock A = 100
Stock B = 45
For the past months, his stocks inversely decreased.
Stock A = m cents / share
Stock B = n cents * share
So the equation is
= 100 (0.01m) + 45 (0.01n)
<span>= m + 0.45n</span>
