Answer:
X=3
Step-by-step explanation:
12x-31=5
12x - 31 - 31 = 5 + 31
12x = 26
12x / 12 = 26 / 12
x = 3
To solve the equation you take 31 to the right by subtracting it from the left then adding it to the right.
From there you divide each side by 12

Answer:
V = 205 in^3 to the nearest whole number
Step-by-step explanation:
V = 4/3 π r^3
Plugging in the given information:
V = 4/3 * 3.14 * 7^2
V = 205.147.
Hello,
The correct answer is B) 280 in²
= 10( 2 × 9 + 10 )
= 10 (2 × 9 = 18 + 10 = 28)
= 10 × 28 = 280
= 280
Answer: 280 in²
In other words.....
= 10(2*9+10)
= 10(18+10)
= 10*28
= 280
Answer: 280 in²
Hope this helps!!!! (:
Answer:
0.549 or 54.9%
Step-by-step explanation:
This is a binomial distribution (Bernoulli's experiment), where the probability of “success” (selecting a battery with acceptable voltage) is 0.9 and the probability of “failure” is 0.1
So, the probability of selecting at least 14 acceptable batteries out of 15 is
where <em>C(n, m) are combinations of n elements taken m at a time</em>.
C(15,14) = 15
C(15,15) = 1
so, the probability we are looking for is
![\large 15*(0.9)^{14}0.1+(0.9)^{15}=0.3431+0.2058 = 0.549 = 54.9\%](https://tex.z-dn.net/?f=%5Clarge%2015%2A%280.9%29%5E%7B14%7D0.1%2B%280.9%29%5E%7B15%7D%3D0.3431%2B0.2058%20%3D%200.549%20%3D%2054.9%5C%25)
