In the United States, 30% of people own a cat and 3% of people own a bird. What is the probability of someone owning both a cat
Alex777 [14]

Answer: 9/100

Step-by-step explanation:

Probability of people own a cat:

P(cat)=30/100=0.3

Probability of people own a bird:

P(bird)=3/100=0.03

Probability of both own a cat and a bird

P(cat and bird)=(30/100) × (3/100)

=90/1000=9/100=9%

What is the answer for 3{5[10+5(500-100)+399]}
notka56 [123]
Okay. Handle 500-100 first. That brings it to 3{5[10+5(400)+399]}. Next, Handle 5(400). That brings you to 3{5{10+2,000+399]}. Then handle all the addition. That leads to 3[5(2,409)]. Next, configure 5(2409). That leads to 3(12045). Then do that one which ends as 36,135 for a final answer.

Solve please<br> A. 1/6m-3=-5<br> B. 2/3x-3=1/2x-7<br> C. x+x/2-4=x/4
AysviL [449]

Answer:

A m = 48

B x = -24

C x = 16

Step-by-step explanation:

A. 1/6m - 3 = 5

1/6m = 5+3

1/6m = 8

multiply both side by 6

m = 8×6

m = 48

B. 2/3x-3 = 1/2 x-7

2/3 x - 1/2 x = -7 +3

1/6 x = -4

multiply 6 to the both side

x = -4×6

x= -24

C.x+x/2-4= x/4

x+x/2 - x/4 = 4

x + l/2 x - 1/4 x = 4

1/4 x = 4

multiply both side by 4

x= 4×4

x = 16
