Step-by-step explanation:

Solving

Volume of rectangular prism (below)

lbh
12 x 12 x 12
144 x 12
1728 ft³

Volume of square pyramid

1/3Bh
1/3 x 144 x √28
48 x 5.29
253.92

Total Volume : 1728 + 253.92 = 1,981.92 ft³ ≅ 1,982 ft³

Answer:

1982 ft^3 ( rounded)

Step-by-step explanation:

The cube bottom is 12 x 12 x 12 = 1728

The pyramid top is 1/3 ( 12*12) * sqrt 28 = 253.99

added together = ~ 1982

( you have to use the HEIGHT of the pyramid for the volume calculation V = 1/3 * base area * height height = sqrt (28) )

Solve for w p=2(l+w)

umka2103 [35]

p = 2(l+w)

divide by 2

p/2 = l+w

subtract l from both sides

p/2 - l = 2

In a box of 25 external hard disks, there are 2 defectives. An inspector examines 5 of these hard disks. Find the probability th

Salsk061 [2.6K]

Answer:

0.3667 or 36.67%

Step-by-step explanation:

The probability of getting at least 1 defective hard disk among the 5 (P(X>0)) is equal to 100% minus the probability of getting none defectives (1-P(X=0)).

If 23 out of 25 hard disks are non-defective, the probability is:

$P(X>0) = 1 -P(X=0)\\P(X>0) = 1 -\frac{23}{25}*\frac{22}{24} *\frac{21}{23} *\frac{20}{22} *\frac{19}{21}\\ P(X>0) = 0.3667=36.67\%$

The probability that there is at least 1 defective hard disk is 0.3667 or 36.67%.
