A million apologies if I’m incorrect
Answer:
They are both the same at 3/4 of an hour
Step-by-step explanation:
We have a system of equations here. The first one is for Friday:
3A + 5B = 6, which says that 3 people at the number of hours for plan A plus 5 people at the number of hours for plan B equals 6 hours total.
The second equation is for Saturday:
9A + 7B = 12, which says that 9 people at the number of hours for plan A plus 7 people at th number of hours for plan B equals 12 hours total.
We can solve this easily using the addition/elimination method. Begin by multipying the first equation through by a -3 to eliminate the A's. That gives you a new first equation of:
-9A - 15B = -18
9A + 7B = 12
You can see that the A's are eliminated, and adding what remains leaves us with
-8B = -6 so
B = 3/4 hour
Now we can sub that back in for B in either one of our original equations to solve for A. I changed the 3/4 to .75 for ease of multiplying:
9A + 7(.75) = 12 and
9A + 5.25 = 12 and
9A = 6.75 so
A = .75 which is also 3/4 of an hour
2/8 *1/7
Multiply the numerators together.
(2)(1)=2
Multiply the denominators together.
(8)(7)=56
2/56 - reduce
divide by 2 for the numerator and denominator
2/2=1
56/2=28
2/8 *1/7= 1/28 ( Answer)
Bucket of lemons picked by Keith =
Bucket of lemons picked by Sally =
We have to determine the more buckets Sally picked.
The more buckets which Sally picked is determined by subtracting the bucket of lemons picked by Keith from bucket of lemons picked by Sally.
More buckets picked by Sally
=
The LCM of 5 and 15 is 15.
=
=
Therefore, Sally picked more bucket of lemons then Keith.
Answer:
The new IQR is 22.
Step-by-step explanation:
We are given the following data of length (in mm) of 12 soybean plants after 3 days of sprouting.
53, 47, 51, 54, 43, 39, 61, 57, 55, 46, 44, 43
Sorted data:
39, 43, 43, 44, 46, 47, 51, 53, 54, 55, 57, 61
Formula:
IQR =
If every measurement is doubled, then, the IQR will also double itself.
Thus,
New IQR =
Thus, the new IQR is 22.
