The probability that a data communications system will have high selectivity is 0.72, and the probability that it will have high

34kurt

Let us assume that even F represents fidelity and event S represents selectivity.

We have been given the probabilities:

P(S) = 0.72, P(F) = 0.59 and $P(S\cap F)=0.33$

We need to find the conditional probability that a system with high fidelity will also have high selectivity. We know the conditional probability formula:

$P(\frac{S}{F})=\frac{P(S\cup F)}{P(F)}$

Upon substituting the given values, we get:

$P(\frac{S}{F})=\frac{0.33}{0.59}$

$P(\frac{S}{F})=\frac{33}{59}=0.56$

Triangle RST was dilated by a scale factor of 1/2. The image, triangle R'S'T', is an isosceles triangle, with each leg measuring

maxonik [38]

Answer:

16 units

Step-by-step explanation:

RST was dilated by a scale factor of 1/2. This means R'S'T' has sides that are 1/2 the length of the sides of RST.

Since the legs of R'S'T' are 8 units, this gives us the equation

8 = 1/2x

Divide both sides by 1/2:

8÷1/2 = x

8 × 2/1 = x

16 = x

Each leg in RST is 16 units.
