Because they were flipped and turned
Answer:
0.2857
Step-by-step explanation:
We define the time it takes to do these dishes to be uniformly distributed between the time 5 minutes and 12 minutes.
a = 5 minutes
b = 12 minutes
Probability of tonight's dish washing being between 6 and 8 minutes
P(6<X<8)
= 8-6/b-a
= 2/12-5
= 2/7
= 0.2857
The probability it will be better 6 and 8 minutes is therefore 0.2857
Q2. The answer is <span>D. 2w + 2 • (3w) ≤112
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>
The perimeter is at most 112 centimeters: P </span>≤ 112
<span>The length of a rectangle is three times its width: l = 3w
</span>P ≤ 112
2w + 2l ≤ 112
l = 3w
2w + 2 * (3w) ≤ 112
Q2.2. The answer is <span>D. 8 cm
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>The length of a rectangle is five times its width: l = 5w
</span><span>The perimeter is at most 96 centimeters: P </span>≤ 96
P ≤ 96
2w + 2l ≤ 96
l = 5w
2w + 2 * 5w ≤ 96
2w + 10w ≤ 96
12w ≤ 96
w ≤ 96 : 12
w ≤ 8 cm
Answer:
