Answer:

Following are the answer to this question:

Step-by-step explanation:

In the given equation there is mistyping so, correct equation and its calculation can be defined as follows:

Given:

$f(x) =\left\begin{array}{cc} 0&x< 1\\0.5& 1 < x$

Calculated value:

$1) \ \ P(x < 3) =1\\\\2) \ \ P(x < 2) = 1-0.5 \\$

$= 0.5$

$3) P(1 < x < 2) = P( x< 2) -p(x< 1)\\\\$

$=0.5-0\\=0.5\\$

$4) \ \ P(x> 2)= 1-P(x$

$=1-0.5\\=0.5\\$

That's why the given equation is true.

oksian1 [2.3K]

Answer:

B and C

Step-by-step explanation:

A. y + 11 = 22 → subtract 11 from both sides:

y = 11

---------------------------------------------------------------------------

B. 8 = 18 - y → subtract 18 from both sides:

-10 = -y → divide both sides by -1:

10 = y

----------------------------------------------------------------------------

C. 60 = 6y → divide both sides by 6:

10 = y

-----------------------------------------------------------------------------

D. $\frac{y}{5}$ = 4 → multiply both sides by 5:

y = 20

-----------------------------------------------------------------------------

E. 10y = 20 → divide both sides by 10:

y = 2
