Can some one help me with 18
dimulka [17.4K]

Answer:

82.6%

Step-by-step explanation:

Conditional probability is defined as:

P(A|B) = P(A∩B) / P(B)

where P(A|B) is the probability of A on the condition of B, P(A∩B) is the probability of both A and B, and P(B) is the probability of B.

Here, we want P(P|K), so:

P(P|K) = P(P∩K) / P(K)

P(P|K) = 0.019 / 0.023

P(P|K) = 0.826

Help me plz 50 points and ill give brainliest if you answer all​
Masteriza [31]

Answer:

11) 2x=-4

Divide both sides by 2:

\frac{2x}{2}=\frac{-4}{2}

x=-2

12) 2^3\cdot \:2^1=2^{3+1}=2^4

(2^4=16) if you wanted the exact value.

13) -3+10=x

Switch sides:

x=-3+10

Rearrange:

x=10-3

x=7

14) 10^2-64

10*10-64

100-64

36

15) \sqrt{100}-5^2

10-5^2

10-5*5

10-25

-15

16) \frac{1}{4}x=-10

Multiply both sides by 4:

4\cdot \frac{1}{4}x=4\left(-10\right)

x=-40

17) \left(2^3\right)^2=2^{3*2}=2^6

(2^6=64) if you wanted the exact value.

18) \left(2^3\right)\left(2^2\right)=2^{3+2}=2^5

(2^5=32) if you wanted the exact value.
