Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².
Speed = distance divided by time. Plug in what you know.
Speed = 51.2 km / 4 hrs. ****** Simplify *******************
Speed = 12.8 km/hr
Answer:
a. yes
b = 0.0563
c. 0.1460
d. 0.7560
Step-by-step explanation:
a. Yes. n = 10 identical trials with two possible outcomes on each with p = 0.25.
b. p(x= 0) = 10!/(0!*10!)* .250* .7510= 1 * 1 * 0.0563 = 0.0563.
c. p(x= 4) = 10!/(4!*6!)* .254* .756= 210 * .0039 * 0.1780 = 0.1460
d. p(x= 1) = 10!/(1!*9!)* .251* .759= 10 * .25 * 0.0751 = 0.1877
p(x≥ 2) =1 - p(x< 2) = 1 – (0.0563 + 0.1877) =0 .7560
Answer:
100b
Step-by-step explanation:
Since 100 cm = 1 meter, we need to multiply b*100 to get the number of centimeters.
