He made an error is step 2
3x + 18 = 2x +8
subtract 2x from each side
x + 18 = 8
Answer:
0.60
Step-by-step explanation:
Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
The probability of a mistake on at least one page is 1 minus the probability of making no mistakes.
P(at least 1) = 1 − P(none)
P = 1 − ₁₁C₀ (0.08)⁰ (0.92)¹¹⁻⁰
P = 1 − (0.92)¹¹
P = 0.60
X = E/W dimension
<span>y = N/S dimension </span>
<span>4x + 4x + 2y + 2y = 64 </span>
<span>8x + 4y = 64 </span>
<span>4y = 64 - 8x </span>
<span>y = 16 - 2x </span>
<span>Area = xy = x(16 - 2x) = 16x - 2x^2 </span>
<span>Maximum of y = ax^2 + bx + c is when x = -b / 2a </span>
<span>so x = -16 / -4 = 4 </span>
Let s be the distance traveled the second day.
1.5s+s=1380
2.5s=1380
s=552
So on the first day he traveled 1380-552=828 miles.
Answer:
80
Step-by-step explanation:
if 88 is 10% higher than his previous weight then his current weight is 110%
divide 88 by 110 then multiply it by 100 to find his previous weight
88 ÷ 110 × 100 = 80
