108 / 1376 is the probability that a student participates in both sports and music.
<u>Step-by-step explanation:</u>
It is given that,
A suburban high school has a population of 1376 students.
- Let the event A be the no.of students participated in sports.
- Let the event B be the no.of students participated in music.
The number of students who participate in sports is 649.
The number of students who participate in music is 433.
<u>To find the probability of event A (sports) :</u>
P(sports) = No.of students participated in sports / Total students.
⇒ 649 / 1376
∴ P(A) = 649 / 1376
<u>To find the probability of event B (music) :</u>
P(music) = No.of students participated in music / Total students.
⇒ 433 / 1376
∴ P(B) = 443 / 1376
From the question, we know that the probability that a student participates in either sports or music is 974 /1376.
∴ P(A∪B) = 974 / 1376
<u>To find the probability that a student participates in both sports and music :</u>
The formula used here is,
P(A∩B) = P(A) + P(B) - P(A∪B)
⇒ 649 / 1376 + 433 / 1376 - 974 /1376
⇒ 108 / 1376
∴ P(A∩B) = 108 / 1376
Answer:
N = D * 1.20
Step-by-step explanation:
In order to calculate the number of dishes that the previous menu had we first need to turn this percentage into a decimal by dividing it by 100
20% / 100 = 0.20
Now we add a 1 to it since we are increasing the old menu by this amount
0.20 + 1 = 1.20
Now we can multiply this by the previous menu dishes (D) to get the new amount of menu dishes (N)
N = D * 1.20
Answer:
70 > I+55
Step-by-step explanation:
The last inequality expresses better this situations.
Emma wants to beat her last record, which was 70 minutes. So, she needs to run in less than 70 minutes.
However, she already ran 55 minutes, the remaining time would be the variable I, so, the sum of them must be less than 70 minutes. So, there are two options to represent this:
I + 55 < 70 or 70 > I + 55.

Answer:
See explaination and answer below
Step-by-step explanation:
Absolute Error:
ae = | E - A |
ae = | 35ft - 33ft|
ae = 2 ft
Percent Error:
pe = 100% * | E - A | / A
pe = 100% * | 35ft - 33ft | / 33ft
pe = 6.06% error
EDIT: 6.1% if asked to the nearest tenth.
