I NEED HELP ASAP Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town.

Which statements are true?

Select each correct answer.


To estimate the percentage well, she would need to collect data for all 35,000 families.

Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.

If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer.

Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer.

I'm fishing. The probability of catching a fish on each cast of my rod (each attempt) is 0.23. Each attempt is independent. If I made 12 attempts and wanted to find the probability that I caught 2 or fewer fish, is this a geometric or binomial situation

Answers

Answer:

This is a binomial situation.

Step-by-step explanation:

For each attempt, there are only two possible outcomes. Either you catch a fish, or you do not. This can mean that either we have a binomial distribution, or a geometric.

However, each attempt is independent, which means that in each attempt, the probability of catching a fish is the same, and that this is a binomial situation.

The probability of catching a fish on each cast of my rod is a binomial distribution.

 

From the question, we can see that there are two possibilities which are whether you catch a fish or not. This gives two possibilities showing that we have a binomial distribution.

 

However, each attempt is independent, which means that one attempt does not affect the other. This is therefore a binomial situation.

Hence the probability of catching a fish on each cast of my rod is a binomial distribution.

Answer:

  -12, -21

Step-by-step explanation:

Let x represent the first number. Then the second is x-9. The other relation is ...

  4x = 2(x-9) -6

  2x = -24 . . . . . subtract 2x, simplify

  x = -12

  x-9 = -21

P-21=34 P=34-21 P=13
What is the value of p?

Answers

Simplifying

P + -21 + -21 = 34 + -21  

-21 + -21 + P = 34 + -21

Combine like terms: -21 + -21 = -42

-42 + P = 34 + -21

Combine like terms: 34 + -21 = 13

-42 + P = 13

Solving

-42 + P = 13

Solving for variable 'P'.

Move all terms containing P to the left, all other terms to the right.

Add '42' to each side of the equation.

-42 + 42 + P = 13 + 42

Combine like terms: -42 + 42 = 0

0 + P = 13 + 42

P = 13 + 42

Combine like terms: 13 + 42 = 55

P = 55

Simplifying

P = 55

Answer:

x=−2 and y=−5

Step-by-step explanation:

Solve3x−2y=4for x:

3x−2y=4

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x /3 = 2y+4 /3 (Divide both sides by 3)

x= 2 /3 y+ 4 /3

Substitute  2 /3 y+ 4 /3 for x in6x−2y=−2:

6x−2y=−2

6( 2 /3 y+ 4 /3 )−2y=−2

2y+8=−2(Simplify both sides of the equation)

2y+8+−8=−2+−8(Add -8 to both sides)

2y=−10

2y /2 = −10 /2 (Divide both sides by 2)

y=−5

Substitute−5 for y in x=

2 /3 y+ 4 /3 :

x= 2 /3 y+ 4 /3

x= 2 /3 (−5)+ 4 /3

x=−2(Simplify both sides of the equation)
