Answer: 2 7/16 yards<span>
To find how much ribbon does she have left over you need to subtract the total ribbon with the ribbon used. Since the denominator of the two number is different, you need to find the least common multiple. LCM of 16 and 2 is 16, so the calculation would be:
</span><span>8 1/16 - 5 1/2=
3 1/16 - (1*8)/(2*8) =
</span>3 1/16 - 8/16=
2 7/16 yards

Step-by-step explanation:
B
Answer:
it lies between 8 hours and 12 hours in a week
Step-by-step explanation:
Since in the question it is mentioned that the distribution consist of uni-modal, symmetric and bell shaped so here the empirical formual to be used for the mean and the standard deviation
Also the 68% would be fall within one standard deviation above and below the mean
Now
1 standard deviation below the mean is
= 10 - 2
= 8 hours
And, above the mean is
= 10 + 2
= 12 hours
Hence, it lies between 8 hours and 12 hours in a week
Answer:
x = -4
Step-by-step explanation:
Subtract x^2-16 from both sides:
x^2 +8x +16 = 0
(x +4)^2 = 0 . . factor
x +4 = 0 . . . . . take the square root
x = -4
The one real solution is x = -4.
