Answer:
Jeremy have 19 dollars left.
Step-by-step explanation:
He withdrew $4.50 3 times, so he withdrew $4.50x3 = $13.50 in total
$32.50 — $13.50 = $19
Jeremy had 19 dollars left on his account.
Using the Central Limit Theorem, it is found that the correct option is:
- B) The random sample of 15 meerkats should be close to 5.2 years-old.
The <em>Central Limit Theorem</em> states that taking a sample of size n for a population of mean
, the sample means are going to be close to
.
- The larger the value of n, the closer the sample mean should be to

In the context of this problem, the sample mean should be close to 5.2 years old, and the correct option is B.

Answer:
3.897 
Step-by-step explanation:
equilateral triangles are also equiangular, meaning the have equal angles.
Triangle sum theory says that angles of a triangle add up to 180.
That means each angle is 60.
A = bh/2
You need the (h). The base of is 3. Perimeter = 9, so each side is 3
Draw a perpendicular line for the height. The line cuts the base in half (1.5)
Using trigonometry you can find the height.
tan 60° = h/1.5
h = height, 1.5 is half of 3, 60° is the base angle.
multiply each side by 1.5
1.5(tan 60°) = h
h=2.598
then substitute h into formula
A= <u>(2.598)(3) </u>
2
A = 3.897 rounded
The answer should be $102
