The school cafeteria has chocolate chip cookies and oatmeal cookies for dessert. What is the probability that exactly 3 of the next 5 students in line will select chocolate chip cookies if everyone selects a cookie, and students prefer chocolate to oatmeal 2 to 1?
Answer:
The probability that 3 out of 5 student select chocolate chip cookie is 2/5
Step-by-step explanation:
The number of student in the sample = 5
The number of student that select the chocolate chip cookie = 3
The ratio of preference of chocolate to oatmeal = 2 to 1
Therefore, out of every 3 cookie, selected, 2 are chocolate while one is oatmeal
Which gives;
The probability that a cookie selected is chocolate = 2/3
The combined probability that 3 out of 5 student select chocolate chip cookie is therefore;
P(3 of 5 select chocolate chip cookie) = 3/5 × 2/3 = 6/15 = 2/5
The probability that 3 out of 5 student select chocolate chip cookie = 2/5.

49x+2=100
Answer:
100 degrees
Step-by-step explanation:
49x+2 and 50x are equal because if you use vertical angles, then opposite interior, then vertical angles again, you would see that they are congruent.
49x+2=50x
x=2

Help me please some one !!!?!?! Find x= y=
Answer:
x=11 y=41
Step-by-step explanation:
(4x+6) is equal to (6x-16) so if you put them equal to each other and solve you get x=11. (y+9) is vertical to (6x-16) so theyre equal as well which you then solve to get 41 for y.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]6x - 16 = 4x + 6[/tex]
Add sides 16
[tex]6x - 16 + 16 = 4x + 6 + 16[/tex]
[tex]6x = 4x + 22[/tex]
Subtract sides 4x
[tex] - 4x + 6x = - 4x + 4x + 22[/tex]
[tex]2x = 22[/tex]
Divide sides by 2
[tex] \frac{2}{2} x = \frac{22}{2} \\ [/tex]
[tex]x = 11[/tex]
_________________________________
[tex]y + 9 = 6x - 16[/tex]
[tex]y + 9 = 6(11) - 16[/tex]
[tex]y + 9 = 66 - 16[/tex]
[tex]y + 9 = 50[/tex]
Subtract sides 9
[tex]y + 9 - 9 = 50 - 9[/tex]
[tex]y = 41[/tex]

PLEASE HELP URGENT!!! A relay race is 1 3 4 miles long. Each relay team has 4 runners. If each runner runs the same distance in the race, how far will each runner run? Choose the correct answer. StartFraction 7 Over 4 EndFraction times StartFraction 4 Over 1 EndFraction = 7, so each runner runs 7 miles. StartFraction 7 Over 4 EndFraction times StartFraction 4 Over 1 EndFraction = 28, so each runner runs 28 miles. StartFraction 7 Over 4 EndFraction times StartFraction 4 Over 1 EndFraction = StartFraction 7 over 16 EndFraction, so each runner runs StartFraction 7 Over 16 EndFraction miles. StartFraction 7 Over 4 EndFraction times StartFraction 4 Over 1 EndFraction = StartFraction 7 over 8 EndFraction, so each runner runs StartFraction 7 Over 8 EndFractionmiles.
Answer:
Each runner runs 7/16 miles
Step-by-step explanation:
Total distance = 1 3/4 miles
Runners per team = 4
If each runner runs the same distance in the race, how far will each runner run?
Distance covered by each runner = Total distance / runners per team
= 1 3/4 ÷ 4
= 7/4 ÷ 4
= 7/4 × 1/4
= 7/16 miles
StartFraction 7 Over 4 EndFraction times StartFraction 4 Over 1 EndFraction = StartFraction 7 over 16 EndFraction, so each runner runs StartFraction 7 Over 16 EndFraction miles.

7/16

next you add 4 and 7 together
11x=18
after that you divide both by 11 to get
1.63 repeating
Answer:
x = 18/11 or 1 and 7/11

4x - 5 + 7x = 13
4x + 7x = 13 + 5
11x = 18
x = 18/11 or 1 and 7/11
