Answer:
You would get tails 75 times, or 75:200
Step-by-step explanation:
5:8 = x:200
multiply 8 by 25 to get 200
multiply 5 by 25 to get x (125)
Probability to get heads is 125 so subtract 200 by 125
200 - 125 = 75
Answer:
amusing you mean 3x^2-8x-16 the answer is when x is equal to -4/3 and 4
Step-by-step explanation:
3x^2-8x-16 ------> (3x+4)(x-4)
3x+4=0 ----> 3x=-4 ----> x=-4/3
x-4=0 ----> x=4
Answer:
Hours spent for snowboarding = 1 hour 35 minutes
Step-by-step explanation:
Total hours spent for skiing and snowboarding = 3 hours
Hours spent for skiing = 1 hours 25 minutes
How long did he spend snowboarding?
Hours spent for snowboarding = Total hours spent for skiing and snowboarding - Hours spent for skiing = 1 hours 25 minutes
= 3 hours - 1 hours 25 minutes
1 hour = 60 minutes
3 hours = 180 minutes
1 hours 25 minutes = 85 minutes
3 hours - 1 hours 25 minutes
= 180 minutes - 85 minutes
= 95 minutes
95 minutes = 1 hour 35 minutes
Hours spent for snowboarding = 1 hour 35 minutes
Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.
