<span>(a)
</span>P (all
B+) = (0.12)(0.12)(0.12)=0.001728=0.1728%
<span>(b)
</span>P (no

<span>(c)
</span>P (not

P (not one B+) = 1 – P (no B+)
<span> = 1 – 0.681472 </span>
P (at least 1 B+) = 0.318528=31.85%
<span>(d)
</span>B. The event in part (a) is unusual because its
probability is less than or equal to 0.05.
11 feet = 132 inches
The boards are x, x and (x-3) inches long.
x + x + x -3 = 132
3x = 135
x = 45
The boards are 45 inches, 45 inches and 42 inches long.
Answer:
≈ 14.6%
Step-by-step explanation:
percentage increase is calculated as
× 100%
increase = 2.75 - 2.40 = 0.35 , then
percentage increase = 
× 100% ≈ 14.6% ( to the nearest tenth )
Answer:
Here u go i hope its corecte I put it as pic
Step-by-step explanation:
So, You know the outer angle, so you need to know the inner angle on <B. so 180-148 is 32. since you know two of the inside angles, and all triangle angles add up to 180 degrees, take 32+83, which is 115, and subtract that from 180, which is 65
Hope this helps!
