This would be 5(6)^2 + 6 - 7
= 180 + 6 - 7 = 179
If ur trying to ask about how many laps r completed in a minute, it’s 3
Answer:
x=6/5 or 1.2
Step-by-step explanation:
I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both
2= -5x+8 (next subtract 8 from both sides)
-6= -5x (divide both sides by -5)
-6/-5=x (the negative cancel out next)
6/5 or 1.20 is x
If your original problem should say 2x=-5x+8
2x=-5x+8 (add 5x to both sides next)
7x=8 (divide by 7 on both sides)
x=8/7
You should know that 10.75 is equal to 1075/100 so now you can simplify it and you will have:
1075/100 = 215/20 = 43/4 and that is the simplest form :)))
I hope this is helpful
have a nice day
Answer:

Step-by-step explanation:
-This is a binomial probability distribution problem.
-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

#We substitute the given parameters in the formula to solve for variance:

Hence, the sample variance is 1.32
