Choose the statement that tells how the area of the reduced design compares to the area of the original design.

timama [110]

The original is 5cm, the reduced is 2.5cm

2.5/5 = 0.5 = 1/2

Area is a square measurement, so the area of the reduced image would be the scale squared, which would be 1/2^2 which = 1/4

The answer is:

The area of the reduced design is 1/4 of the area of the original.

Consider a uniform distribution created by a random number generator. The distribution looks like a square with a length of 1 an

The rigorous way to do this would be to compute a few integrals, but less work is usually better. Each of these probabilities correspond to the areas of rectangles. Each rectangle will have a height of 1, and the probability of interest will tell you everything you need to know about their lengths.

$\mathbb P(0\le X\le0.4)\implies \text{length}=0.4\implies\mathbb P(0\le X\le0.4)=0.4\times1=0.4$

$\mathbb P(0.4\le X\le1)\implies \text{length}=0.6\implies\mathbb P(0\le X\le0.4)=0.6$

Alternatively, you can use the fact that $\mathbb P(0.4\le X\le 1)=1-\mathbb P(0\le X\le 0.4)$ to get the same result.

$\mathbb P(X>0.6)=\mathbb P(0.60.6)=0.4$

$\mathbb P(X\le0.6)\implies \text{length}=0.6\implies\mathbb P(X\le0.6)=0.6$

$\mathbb P(0.23\le X\le0.76)\implies \text{length}=0.76-0.23=0.53\implies\mathbb P(0.23\le X\le0.76)=0.53$
