Add those up to get 188. Then multiply this by 2 and you get 376.

Your answer is D. (376)

P.S if this helped you out, please give me brainliest if you don't mind. I am only a few more from leveling up :D

kolbaska11 [484]
We're looking for the volume, since it's trying to find out the cost for filling the entire box.
We have our length, width, and height.
8, 6, and 1.
We're multiplying 8, 6 1, and 0.3 since it is $0.3 per sq ft,
Our equation is:
0.3 (8x6x1) = x
8 x 6 x 1 = 48.
48 x 0.3 is 14.4
$14.4 is your answer
Hope this helps!

Ray Of Light [21]

Answer:

The probability that at least 1 defective card is in the sample is 0.9644

Step-by-step explanation:

Here

N = 140

and n = 20

We will use the below given formula

P(at least 1 defective) = 1 - P( 0 defectives)

P( 0 defectives) =

= \frac{^{20}C_0 * ^{120}C_{20}}{ ^{140}C_{20}}\\= 0.0356 1-0.0356 \\= 0.9644
