Find the value of x, y and z
tangare [24]

Answer:

Step-by-step explanation:

8x = 9x - 7

-x = -7

x = 7

9(7)-7= 63-7=56

8(7)= 56

13y+7+56=180

13y+63=180

13y=117

y=9

13(9)+7= 117+7= 124

5y-11+56=90

5y+45=90

5y=45

y=9

5(9)-11+9(7)-7= z

45-11+63-7=z

34+56=z

90=z

A 2L punch recipe calls for orange and ginger ale in the ratio of 2:5
Nastasia [14]

Answer:

a) 4/7 L = 0.57 L

b) 25/7 L = 3.57 L

Step-by-step explanation:

The ratio of orange juice to ginger ale is 2:5.

Add 2 + 5 = 7.

The ratio of orange juice to ginger ale to total drink is 2:5:7.

a) The fraction of orange juice is 2/7 of the total drink.

To make 2 L, you will need 2/7 of 2 L to be orange juice.

2/7 * 2 L = 4/7 L = 0.57 L

b) The fraction of ginger ale is 5/7 of the total drink.

5/7 * 5 L = 25/7 L = 3.57 L

Determine if asking 100 people which brand of car they drive is a binomial experiment or not. Explain
Leya [2.2K]

Answer:

The provided statement is not a binomial experiment.

Step-by-step explanation:

Four conditions of a binomial experiment:

There should be fixed number of trials

Each trial is independent with respect to the others

The maximum possible outcomes are two

The probability of each outcome remains constant.

For example:

Binomial distribution: Asking 200 people if they ever visit to new york.

Not Binomial distribution: Asking 200 people how much they earn in a week.

Now, observe the provided information:

We need to determine that, asking 100 people which brand of car they drive is a binomial experiment or not.

Clearly it is not a binomial experiment because the maximum possible outcomes are not two.

Therefore, the provided statement is not a binomial experiment.
