Answer:
d. 16x² + y² = 16
Step-by-step explanation:
Standard form of an ellipse is:
x² / a² + y² / b² = 1
If b > a, the ellipse has a vertical orientation.
We can ignore options b and c, since they have minus signs in them.
Convert the other options to standard form:
a. x² / (1/16) + y² / (1/25) = 1
x² / (1/4)² + y² / (1/5)² = 1
1/4 > 1/5
d. x² + y² / 16 = 1
x² / 1² + y² / 4² = 1
1 < 4
e. x² / 16 + y² = 1
x² / 4² + y² / 1² = 1
4 > 1
Of these three options, only d is a vertical ellipse.

This question is incomplete, the complete question is;
You decide to record the hair colors of people leaving a lecture at your school. What is the probability that the next person who leaves the lecture will have blonde hair
?
Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Blonde Red Brown Black Gray
31 25 18 40 42
Answer: the probability that the next person who leaves the lecture will have blonde hair is 0.1987
Step-by-step explanation:
Given that;
HAIR COLOR FREQUENCY
Blonde 31
Red 25
Brown 18
Black 40
Gray 42
Total 156
So
there were 156 people all together
and out of the 156, 31 of them were blonde.
now the probability that the next person who leaves the lecture will have blonde hair will be;
⇒ 31 / 156 = 0.1987
Therefore, the probability that the next person who leaves the lecture will have blonde hair is 0.1987
Answer:
The amount at the end of second quarter is $1842.704
Step-by-step explanation:
Given as :
The principal in saving account = $1640
The rate of interest = 6 % compounded quarterly
The time period = 6 months
Now,<u> from compounded method</u>
The amount at the end of first quarter = 
= principal + 6 % of principal
I.e = $1640 + 6 % × $1640
Or, = $1640 + $ 98.4
∴ = $1738.4
Again ,
The amount at the end of second quarter = 
= 
+ 6 % of
I.e = $1738.4 + 6 % × $1738.4
Or, = $1738.4 + $104.304
∴ = $1842.704
So, The amount at the end of second quarter = = $1842.704
Hence , The amount at the end of second quarter is $1842.704 Answer
