Answer:

a) The area of the largest face = 2400 cm², The area of the largest face = 0.24 m²

b) The volume of the cuboid = 48000 cm³, The volume of the cuboid = 0.048 m³

Step-by-step explanation:

The volume of any cuboid = L × W × H, where

L is its length

W is its width

H is its height

∵ A cuboid measures 60 cm by 40 cm by 20 cm.

→ Assume that L = 60 cm, W = 40 cm, H = 20 cm

∵ The largest face is the face who has the largest dimensions

∵ L and W are the largest dimensions

∴ The area of the largest face = L × W

∴ The area of the largest face = 60 × 40

∴ The area of the largest face = 2400 cm²

∵ 1 cm = 1/100 m

∴ 1 cm² = (1/100)² m² = 1/10000 m²

∴ The area of the largest face = 2400 × 1/10000

∴ The area of the largest face = 0.24 m²

∵ The volume of the cuboid = L × W × H

∴ The volume of the cuboid = 60 × 40 × 20

∴ The volume of the cuboid = 48000 cm³

∵ 1 cm = 1/100 m

∴ 1 cm3 = (1/100)³ m³ = 1/1000000 m³

∴ The volume of the cuboid = 48000 × 1/1000000

∴ The volume of the cuboid = 0.048 m³

Answer:

Last option (1/2)^3 = .125

Step-by-step explanation:

1/2 (1.035)^5 =0.579637

(2/3)^2 = 4/9 = .4444

.2^2/.3^2 = 0.04/0.09 = .44444

(1/2)^3 = 1/8 = .125

So we can clearly see the last one as the answer

Answer:

0.7995 = 79.95% probability that the sample will contain at least three defectives.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

$E(X) = np$

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that $\mu = E(X)$ , $\sigma = \sqrt{V(X)}$ .
