Uhh help lol 5.3x + y = 28.5 4.2x + 3.1y = 27.2 find x and y

navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

$y = -5.3x+28.5$

Next, substitute y in the bottom equation.

$4.2x + 3.1(-5.3x + 28.5) = 27.2$

$5.3x + y = 28.5$

Simplify.

$4.2x + -16.43x + 88.35 = 27.2$

Combine like terms.

$-12.23x + 88.35 = 27.2$

Isolate x on one side.

$-12.23x = -61.15$

Isolate x.

$x = 5$

Substitute x into $5.3x + y = 28.5$

$5.3(5) + y = 28.5$

Simplify.

$26.5 + y = 28.5$

Isolate y.

$y = 2$

$x = 5 \\y = 2$

If two events a and b are independent and you know that p(a) = 0.70, what is the value of p(a | b)?

Afina-wow [57]

Hello :
note 1 :
p(A|B) = p(A∩B)/ p(B)....(1)

note 2 :
 A and B independent: p(A∩B) = p(A)×p(B)......(2)
subsct in (1) : p(A|B) = p(A∩B)/ p(B)
= (p(A)×p(B))/p(B)
p(A|B) = p(A) = 0.70
