Which statement is true about whether Z and B are independent events?

Answer:

Z and B are independent events because P(Z∣B) = P(Z).

Step-by-step explanation:

Z and B are independent events

When Z  and B  are independent events then

P(Z and B) = P(Z) * P(B)

P(Z∣B)= \frac{P(Z and B)}{P(B)}

P(Z∣B)= \frac{P(Z)*P(B)}{P(B)}

We cancel out P(B) on both sides

P(Z|B) = P(Z)

Which expressions is equivalent to 2r+(t+r)
azamat

Answer:

t+3r

Step-by-step explanation:

This is a one step solution

All you do is add like terms

In this case the only like terms are the varibles r

2r+(t+r)

so if you add all of the rs together there would be 3rs

So the rest of the problem would continue as normal while bringing the 3r to the end

t+3r

A x 4 = E B ÷ 4 = E C + 4 = E D - 4 = E ___________ &amp; A + B + C + D = 100 Challenge *what is the value of E ?*
tresset_1 [31]
A×4  = E, so A = E/4
B/4   = E, so B = 4E
C+4  = E, so C = E=4
D-4   = E, so D = E+4
and
A+B+C+D=100.

now substitute the values that  we got of A, B, C and D in the equation, to get,
(E/4) + 4E + E-4 + E+4 = 100
(E/4) + 4E + 2E = 100
(E/4) + 6E = 100
(E+24E)/4 = 100
E+24E = 100×4
25E = 400
E = 400/25
E = 16
