Answer:
rs.645
Step-by-step explanation:
Since we know the amount deducted and added based off of accuracy of the boy's shot, we can simply input numbers and add.
Since he missed five shots multiply 6 by 5. He lost 30.
Since he hit 45 shots multiply 45 by 15. He made 675.
675-30=645
So, the boy made rs.645
Answer: total number of teaspoons of spices in the dish =3.25 teaspoons
Step-by-step explanation:
Step 1
Listing the spices and their quantities , we have
Salt = 1/2 teaspoon
Orégano =1 1/4 teaspoon =5/4 teaspoons
Basil = 3/4 teaspoon
Pepper= in half as much pepper as salt -- This means that the quantity of pepper should be 50% more in quantity than salt
Therefore quantity of pepper = 50% x 1/2 = 0.5 x 0.5= 0.25
0.25 + 1/2 = 0.25 + 0.5 = 0.75 = 3/4 teaspoon of pepper.
Step 2
Adding the amount of spices we have
1/2 + 5/4+ 3/4+ 3/4 = 2+ 5+3+ 3/4 = 13/4 = 3 1/4 teaspoons of spices = 3.25 teaspoons of spices .
Answer with explanation:
Given : A clinical trial tests a method designed to increase the probability of conceiving a girl.
Also, in a normal case the probability of conceiving a girl is 0.5.
Let p be the proportion of girls born.
Then , we have
Sample size : n= 345
The sample proportion of girls born =
Critical value : 
The confidence interval for population proportion is given by :_
Since the confidence interval do not contains 50% that means there is increase in the probability of conceiving a girl, then it can be concluded that we have statistical evidence that the the clinical trial method increase the probability of conceiving a girl.
