Answer:
IQR = 5
The IQR covers 50%
Step-by-step explanation:
The interquartile range is the right line of the box minus the left side of the box
UQ - LQ = IQR
8 - 3 = 5
The interquartile range is 5
Now to find the percent in the interquartile range.
The Box divides the data in quartiles or 25%
The dot to the left line is 25%
The left line to the middle is 25%
The middle to the right line is 25%
The right line to the right dote is 25%
From the left line to the right line is 25% + 25% = 50 %
The IQR covers 50%
Answer:
16 N
Step-by-step explanation:
If the 7 N force is at 0°, and the 11 N force is at 60°, then the components of the resultant force are:
Fₓ = 7 cos 0° + 11 cos 60° = 12.5
Fᵧ = 7 sin 0° + 11 sin 60° ≈ 9.53
The magnitude of the resultant force is:
F = √(Fₓ² + Fᵧ²)
F ≈ 15.7
Rounded to the nearest whole number, the magnitude is 16 N.

Answer:
- Mark: s = 200 +20j
- Ryan: s = 350 +15j
- 30 jobs
Step-by-step explanation:
The amount in savings (s) will be the initial amount plus the product of the pay per job and the number of jobs (j).
<u>Mark</u>
He initially has $200, and is paid $20 per job. His savings will be ...
s = 200 +20j
<u>Ryan</u>
He initially has $350, and is paid $15 per job. His savings will be ...
s = 350 +15j
<u>Same Savings</u>
The savings will be the same when the difference between the amounts is zero:
s - s = 0
(200 +20j) -(350 +15j) = 0 . . . . . substitute the expressions for s
-150 +5j = 0 . . . . . collect terms
-30 +j = 0 . . . . . . . divide by 5
j = 30 . . . . . . add 30
The brothers will have the same amount in savings after they each work 30 jobs.
The answer is 21x-28 hope it helps
