Answer:
B. Multiply the divisor and dividend by 100.
Step-by-step explanation:
Multiply by 100 to get rid of the decimal
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.
Answer:
P(Dᶜ )=0.41
Step-by-step explanation:
In the survey, the event D is the event of people who prefer to flirt directly in person.
Given that P(D)=0.590.
If someone is selected randomly, the probability that the individual prefers to flirt directly in person is 0.590.
If the person does not like to flirt in person, the probability of it will be the complement of event D.
From Probability Theory,
P(D)+P(Dᶜ )=1
0.590+P(Dᶜ )=1
P(Dᶜ )=1-0.590=0.41
The probability that the selected person does not like to flirt in person is 0.41.
