Answer:
4. A.
14. A. 38.4 mph
<u>(I estimated the line to be 1.5 inches. Measure the line IRL so I can adjust the answer)</u>
15. D.
16. B.
17. A.
Step-by-step explanation:
4. Rearrange the numbers; 44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56
Minimum = 44
First Quartile = 46
Median = 50
Third Quartile = 55
Maximum = 56
14. 12 × 8 = 96. 96 × 1.5 = 144
144/1 ÷ 15/4 = 144/1 × 4/15 = 576/15 = 38.4
15. 35(2) + [ -1/2(15) ] = 35(2) - 1/2(15)
16. The new numbers for 540 students are
8/60 = 72/540 Walked: 72
7/60 = 63/540 Car: 63
3/60 = 27/540 Bicycle: 3
42/60 = 378/540 Bus: 378
17. 280 × 9 = 2,520
Increase by 25% = 125% of the total
2,520 × 1.25 = 3,150
3,114 - 3,150 = -36
Answer:
5
Step-by-step explanation:
180=9×w
length=9
width=20
perimeter=58
Hope this attached file will help u.
To know if Diagonals are perpendicular we need to know two line's slope
If two lines are pependicular their slope m1×m2=-1
For if they are making rhombus two opposite equal sides so u need to know the distancebetween the points.
Divide total price by amount bought:
120.96 / 144 = 0.84
It cost $0.84 for 1 square foot.
