Step-by-step explanation:
The equations that could be used to determine the number of chicken wings and sliders in the combination meal is:
75w + 250s = 800
w = 2s
Where:
w = chicken wings
s = sliders
The two equations derived from the question are known as simultaneous equations. Both equations have to be solved together in order to determine the number of wings and sliders.
The total calories of wings = number of wings x calories of each wing
75 x w = 75w
The total calories of sliders = number of sliders x calories of each sliders
250 x s = 250s
Answer:
look below but sorry that i dont know part b
Step-by-step explanation:
y = 5/2x-3
slope=5/2 y-int = -3
y=x-9
slope=1/1 y-int=-9
y=5x
slope= 5/1 y int=0
y=-1/2x +5
slope=-1/2 y-int= 5
plzzzz plzplz mark me brainliest thank you!!!!!!!!!!!!
Answer:
9.5
Step-by-step explanation:
1. Arrange in ascending order
4 5 6 7 8 9 10 11 12
2. Upper Quartile formula:
3×(N+1)÷4
3. Number of terms (N) = 9
4. Apply:
3×(9+1)/4
=3×10/4
=30/4
=7.5th term
5. 7.5th term is the average of the 7th and the 8th term so
Take average
7th term is 9 and 8th term is 10
6. Find average of 9 and 10 = 9.5
7. ANSWER : THE UPPER QUARTILE IS 9.5 FOR THE GIVEN DATA
Answer:
Hamburger Chicken
Adults 65 60 125
children 55 20 75
120 80 200
a)What is the probability that a randomly selected individual is an adult?
Total no. of adults = 125
Total no. of people 200
The probability that a randomly selected individual is an adult = 
b) What is the probability that a randomly selected individual is a child and prefers chicken?
No. of child prefers chicken = 20
The probability that a randomly selected individual is a child and prefers chicken= 
c)Given the person is a child, what is the probability that this child prefers a hamburger?
No. of children prefer hamburger = 55
No. of child = 75
The probability that this child prefers a hamburger= 
d) Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?
No. of adults prefer chicken = 60
No. of total people like chicken = 80
A person has ordered chicken, the probability that this individual is an adult= 
Answer:
Maybe how many people are in the park
