Answers
Answer with explanation:
An experiment is said to be binomial, if it has n number of trials,and out of n trials,when each trial is performed Independently, there are only two possible outcomes,one Success and other will be failure.
In option A,
Number of trials = 24,which is fixed.
Success= getting 4,when a die is rolled.
Failure = Getting ,number other than,4 , that is , 1,2,3,5,6.
So, This is Binomial Experiment.
In Option B,
Number of trials is not fixed.So, This is not Binomial Experiment.
In Option C
Number of trials is not fixed.So, This is not Binomial Experiment.
In Option D
Number of trials = 24
But, there are more than two possible outcomes.So,this is not a Binomial Experiment.

d ---- sin30 =5/x
Answer:
D. sin 30° = 5/x
Step-by-step explanation:
recall that for a right triange, considering one of the acute angles θ
sin θ = length of opposite side / length of hypotenuse
from the picture, we can see that
θ = 30°, length of opposite site = 5 and length of hypotenuse = x
substituting this into the above equation
sin 30° = 5/x

As per the concept of unitary method, the price of gasoline per gallon is $2.45.
To find the price of gasoline per gallon, we can use a simple mathematical calculation. The formula to calculate the price per gallon is:
Price per Gallon = Total Cost / Number of Gallons
Given that Denise paid $27.44 for 11.2 gallons, we can plug these values into the formula to find the price per gallon:
Price per Gallon = $27.44 / 11.2 gallons
Now, let's perform the calculation:
Price per Gallon = $2.45 (rounded to two decimal places)

Answer:
Step-by-step explanation:
In this question, we're trying to find the price of 1 gallon of gasoline. We know this because in the question, it says "per gallon", meaning that we are trying to find the price for 1 gallon.
We know that:
- Denise paid $27.44 for 11.2 gallons of gas
With the information above, we can solve the question.
In order to find how much 1 gallon of gas cost, we would divide 27.44 by 11.2
Divide:
When you're done solving, you should get 2.45.
This means that each gallon of gas costs $2.45
