Mia takes a random sample of 10 of her coworkers and asks them each how many pets they have. Assume that
their results are independent, and let X represent the average number of pets in the sample.

Answers

Answer 1

Answer: Each trial isn’t being classified as a success or failure, so X is not a binomial variable.

Step-by-step explanation:

Answer 2

X is not a binomial variable since each trial is not categorized as a success or failure.

What is a binomial variable?

The likelihood of failure increased to the power of the difference between the number of successes and the number of tries is multiplied by the chance of succeeding raised to the power of the number of successes.

The chance of success for the trials in question in a binomial distribution must stay constant. Because there are only two possible outcomes when flipping a coin, the likelihood of doing so is 0.5 for each trial.

Since lX indicates the typical number of pets in the sample and their outcomes are independent, X is not a binomial variable.

Brandon treated his friends to lunch which cost him $32.60. He left a 20% tip for the waitress. How much was his total bill including tip?

Answers

Answer:

39.12

Step-by-step explanation:

First you find 20% of 32.60

32.6 * 20/100

32.6 * 0.2

= 6.52

So the tip is $6.52

Add the tip and the regular cost

32.60 + 6.52 = 39.12

$39.12 is the total amount he paid

I double checked and that answer is correct. The total including 20% tip is $39.12 :)

150 into the ratio 4:11

Answers

9514 1404 393

Answer:

  40 : 110

Step-by-step explanation:

There are a number of ways you can go at this. One of my favorite is to consider the value of a "ratio unit." Here, a total of 4+11 = 15 "ratio units" represent the total to be divided: 150. So the value of each one is ...

  150/15 = 10

Then the division is ...

  4 : 11 = 10·4 : 10·11 = 40 : 110

_____

Alternate solution

Let x represent the larger share. Then the ratio is ...

  (150 -x) : x = 4 : 11

Cross-multiplying gives ...

  11(150 -x) = 4x

  1650 = 15x . . . . . add 11x, simplify

  110 = x . . . . . . . . . divide by 15; the larger share

  150-x = 150-110 = 40 . . . . . . the smaller share

The division is 40 : 110.

Answer:

Step-by-step explanation:

So Blakes sleep 8 hours per night during the school day

8 hours/night...................................100%

6.5 hours/night...................................?

6.5*100/8=81.25

the change in percentage is 100-81.25=18.75%

the percentage change is 18.75

if it is easier for you, another method is:

8-6.5=1.5 subtract the original amount to the new amount

1.5/8=0.1875 divide by the original amount

0.1875*100=18.75 find the percentage

30% times by x is 9. (x is the number we’re trying to figure out) another way to put this equation is 30/100 times x = 9. now let’s multiply both sides by 100 and divide both sides by thirty. we have x = 9 times 100/30. so the answer is 30. the puppy’s full weight is 30 pounds. hope this helps :)

The adult weight of the puppy of Andre puppy be 30 pounds.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Andre has a puppy that weighs 9 pounds.

The vet says the puppy is now at 30% of its adult weight.

Let n pounds be the weight of an adult.

Using the percentage formula,

9 = 30 x n /100

n = 900/30

n = 30 pounds

Therefore, adult puppy weight is 30 pounds.

Victor has some model planes. Last weekend, Victor and his grandfather built four more model planes to add to his collection. Now Victor has a total of 42 model planes.

Part A: In the first box, enter an equation to represent the number of planes, x, Victor originally had.

Part B: In the second box, enter the number of planes represented by x in this situation.

Answers

Answer:

x = 42 - 4

x = 38

Step-by-step explanation:

Given that :

Initial number of plane models = x

Number of additional models built = 4

Total number of planes = 42

Total = initial amount + additional amount

42 = x + 4

Make x the subject

42 - 4 = x + 4 - 4

x = 42 - 4

X + 4 = 42

X = 42 - 4

X = 38
