Step-by-step explanation:
Given : In a hypothetical study looking at the scores of 100 people in an entrance exam, it was determined that the average score was 95 with a standard deviation of 10.
i.e.
Let x denotes the scores.
We assume that the scores are normally distributed.
Then, the proportion of individuals in this population have a score greater than 115 will be :-

Answer:
Unitary Method
Step-by-step explanation:
If the item is not listed with the unit price we can use different methods to calculate its unit price.
Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.
We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.
For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:
6 pounds costs $7.00
1 pound costs: dollars.
And that is how we calculate the price of each unit.
Answer:
$2347; $46,940 from deposits and $5060 from interest
Step-by-step explanation:
In this question, we are asked to calculate the 3 things. The amount deposited per month, how much of total deposits comes from the total $52,000 and the total amount coming from interest.
To proceed, we first calculate the regular payment. Afterwards we calculate the deposit to get the amount coming from the $52,000 total deposit.
Using the formula interest = Annuity - Total deposit , we get the value of the interest.
