1 hour = 3600 seconds
3 × 3600 = 10800
<em>10800 yards per hour
</em>
1 mile = 1760 yards
<em>
</em>10800 ÷ 1760 = 6.13
6.13 miles per hour
Answer:
The length of the original rectangle is 14 meters and the width of the original rectangle is 12 meters
Step-by-step explanation:
Let
l ----> the length of the original rectangle
w ----> the width of the original rectangle
we know that
----> equation A
----> area of a square
Solve for w
square root both sides
-----> this solution not make sense
so
Find the value of L
therefore
The length of the original rectangle is 14 meters and the width is 12 meters
Answer:
0.6247
Step-by-step explanation:
In order to find the frequency of people who complete the test between 45 and 65 minutes, we have to find z
Z = (x – mean)/standard deviation
Le x be the time to complete the test
Z1 = (45 – 60)/10 = -1.5
Z2 = (65 – 60)/10 = 0.5
Then we use the z table to find the area under the curve.
Area for Z1 = 0.4332
Area for Z2 = 0.1915
The relative frequency is the area between the two z-scores:
0.4332 +0.1915 = 0.6247
