Answer:
y=4x-3
Step-by-step explanation:
Parallel lines will always have the same slope (the number that comes before x in an equation). So, we can plug in 4 to the equation.
y=4x+?
Let's say the ? is b. If we plug in the point (1,1) into y=4x+b, we get
1=4(1)+b
reduce
1=4+b
subtract 4 from both sides
-3=b
and now we can add b=-3 into the original answer, and we get y=4x-3!
this is a binomial problem: p = 0.7 and q = 0.3
a) (0.7)^6
b) (6C4)(0.7)^4(0.3)^2
c) Pr ( at least 4) = Pr(4) + Pr(5) + Pr(6) = (6C5)(0.7)^5(0.3) + (0.7)^6
d) Pr (no more than 4) = 1 - Pr(at least 4) = 1 - (answer from c)
Answer:
16
Step-by-step explanation:
Let the number = x
x + x/2 - 20 = 1/4 x
3/2 x - 20 = 1/4x Multiply by 4
3*2 x - 80 = x
6x - 80 = x
6x - x - 80 = 0
5x - 80 = 0
5x = 80
x = 16
Check
16 + 8 - 20 = 1/4 * 16
24 - 20 = 4
4 = 4
X = 5y
x - y = 1308
5y - y = 1308
4y = 1308
y = 1308/4
y = 327
x = 5y
x = 5(327)
x = 1635
ur 2 numbers are 327 and 1635 <=
