If 28 tiles is placed in 7 rows then each row has 4 tiles.
<u>Step-by-step explanation:</u>
The total number of tiles given =28.
The number of rows = 7.
The number of tiles in each row is given by diving the total number of tiles given by the number of rows.
No of tiles in each row=
.
No of tiles in each row =
.
No of tiles in each row = 4.
Note: You can replace the values according to the given values.

Answer:
0.323 = 32.3% probability that the director chooses 3 boy kittens and 5 girl kittens.
Step-by-step explanation:
The kittens are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:

In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

A TV studio has brought in 8 boy kittens and 10 girl kittens for a cat food commercial.
This means that 
We want 3 boys, so 
The director is going to choose 8 of these kittens at random to be in the commercial.
This means that 
What is the probability that the director chooses 3 boy kittens and 5 girl kittens?
This is P(X = 3).


0.323 = 32.3% probability that the director chooses 3 boy kittens and 5 girl kittens.
Answer:
The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
Step-by-step explanation:
Given
Size of Gas = 12 gallon of gas
Distance = 456 miles
Calculating the number of miles her car travel per gallon of gas.
This in calculated by distance/size of gas
By substituton, it becomes
Number of miles = 456 miles/12 gallons ------ divide
Number of miles = 38 miles / gallon.
Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
