Answer:
10 hours
Step-by-step explanation:
45 pages per 1 hour and 30 minutes, or 60 min +30 min =90 min
90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages
90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300
? minutes = 90*300/45 = 600 minutes
to read 300-page book will take 600 minutes = 10 hours
Given:
Pool swimming Ocean swimming Total
Age 30 and younger 228 54 282
Over 30 years old 142 185 327
total 370 239 609
Frequencies:
Pool swimming Ocean swimming Total
Age 30 and younger 228/609 = 0.37 54/609 = 0.09 282/609 = 0.46
Over 30 years old 142/609 = 0.23 185/609 = 0.30 327/609 = 0.54
<span>total 370/609 = 0.61 239/609 = 0.39 609/609 = 1.00</span>
<span>The relative frequency (rounded to the nearest hundredth) of a person over 30 years old who prefers to swim in the ocean is 0.30</span>
Answer:
Yes you are correct
Step-by-step explanation:
If you split them they all are worth zero which is nothing
Answer:
Each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
Step-by-step explanation:
Make a sketch and find an isosceles triangle formed by the diagonal, shorter base and the lateral side of the trapezoid.
Thus you have the lateral sides of the trapezoid congruent to the shorter base.
Your trapezoid then has the sides of 5:3:3:3 units.
In total, there are 5 + 3 + 3 + 3 = 14 units.
Hence, each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
