Answer:
Yes, It is an binomial experiment.
Step-by-step explanation:
Consider the provided information.
There are 4 conditions to identify that a distribution is binomial or not.
- Binary: That means only two possibility success or failure.
- Fixed number of trials.
- Independent trials.
- The probability of success is constant from trial to trial.
Now consider the provide procedure:
Binary condition is satisfied because baby can be male or not.
Trials are independent because couples were selected randomly. It satisfy the 2nd condition.
There are 70 couples it satisfy the 3rd condition.
Probability of success will be constant as couples selected randomly. It satisfy the 4th condition.
Yes, It is an binomial experiment because procedure satisfies all the criteria for a binomial distribution.
Hence, It is an binomial experiment.
1.8 x 5.99 = 10.782
10.782 rounded to the nearest hundredth is 10.78
so the answer is 10.78
Answer:
Rate is 8.5%
Step-by-step explanation:
Step 1: Write the given terms
Principal (p)=Rs8800
Rate(r)=?
Time(t)=3.5 years
Interest=Rs2618
Step 2: Write the formula for calculating Simple interest
Step 3: Make r the subject of the equation
Step 4: Find the value of r by substituting the values in step 1
Hence, the rate is 8.5%
A. p = 8n - 30
Each item n is $8.
Expenses totaling $30 are subtracted.
So if the profit (p) is $170.00,
170 = 8n - 30
Now you need to solve.
Add 30 to both sides.
200 = 8n
Divide both sides by 8.
25 = n
25 items were bought.
b. If 25 items were bought, but the expenses were instead $40, what would be the total profit?
p = 8(25) - 40
p = 200 - 40
p = 160
The profit decreased by 10.
