For part A, if P is the center of that triangle, then PR and PT have the same length; therefore, triangle RPT is isosceles. For part B, by the definition of an incenter...if P is an incenter, then it is the place where all the angle bisectors meet. Therefore, angles SRP and PRT are congruent, as are angles STP and PTR. Since the vertex angle measures 64, then each of the base angles by the isosceles triangle theorem measure 58. Half of 58 makes the base angles within the smaller triangle measure 29. And if both of those measure 29, by the triangle angle-sum theorem, 180-29-29 = 122 And that's the measure of angle RPT. Eek.
Answer:
0.579 is the probability that a household has a VCR given they have a TV.
Step-by-step explanation:
We are given the following in the question:
Probability of all households have a TV = 88% = 0.88

Probability of all households have a TV and VCR = 51% = 0.51

We have to find the probability that a household has a VCR given they have a TV.
The conditional probability is given by:

0.579 is the probability that a household has a VCR given they have a TV.
Rounding numbers means you change the number to a closer, easier number. For example if you want to round 56 to the nearest tenth, it would round to 60.
Estimating numbers is when you guess numbers. For example, if you want to estimate the measure used to measure a bed, i would estimate feet.
I hope this helped:))
