For 20 months, Molly deposited $86.50, so she deposited a total of 86.5 * 20, namely 1730 bucks.
now, every month she deflated her account by $24.50 to pay for her singing lessons, she did that every month, namely for 20 months so she deflated the account balance by 24.5 * 20, or 490 bucks.
so, she deposited 1730 and deflated it by 490, 1730 - 490 = 1240, that's all that's left in the account.
for the Summer Camp, she spent 1/4 of that, what's a quarter of that? well is just their product, (1/4) * 1240.
Answer:
The value of n is 5
Step-by-step explanation:
Here, we want to get the value of n
To get this, we will need to use the appropriate trigonometric identity
As we can see, n represents the opposite as it the side that faces the angle given
m is the hypotenuse as it is the side that faces the right angle
The last side is called the adjacent
The trigonometric identity we want to use is that which connects the opposite to the adjacent
The appropriate trigonometric identity to use in this case is the tan
Thus;
Mathematically, the tan is the ratio of the opposite to the adjacent
hence;
tan 30 = n/ 5 √3
n = 5 √3 * 1/ √3
n = 5
Part A. For finding the quartiles, box plot would be the best to represent the range of scores of the students.
Part B. The first step is to order the data: 2 3 3 3 3 4 5 6 7 8 14. Next, you will find the median. The median is 4. So, second the quartile = 4 The median splits the remaining data into two sets. The first set is 2 3 3 3 3 and the median of this set is 3. So, first quartile = 3. The second set is 5 6 7 8 14 and the median of this set is 7. And the third quartile = 7
