Answer:
A
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. Hence, the two shorter sides created on diagonal RT ("6x-7" and "x+28" ) are equal.
<em>We can set them equal and solve for x:</em>
<em></em>
<em />
<em>So the side length of 6x -7 is:</em>
<em>6(7)-7 = 35</em>
<em>and the side length of x + 28 is:</em>
<em>7 + 28 = 35</em>
<em />
<em>THus, the diagonal RT = 35 + 35 = 70 units</em>
<em />
<em>Answer choice A is right.</em>

Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:
Let x be the number calls that reach to live person.
We have to find
Using the binomial probability distribution, we have:
Therefore, the probability that none of them reaches a live person is 0.3277
a) see attachment for graph
b) D: [0, 2.5] <em>time cannot be negative so the x-values start at 0</em>
R: [0, 100] <em>height cannot be negative so the y-values start at 0</em>
c) 84 ft <em>refer to the red coordinate on the graph</em>
d) 1.75 seconds <em>refer to the blue coordinate on the graph</em>
e) 2.5 seconds <em>refer to the green coordinate on the graph</em>
<em />
When looking for coordinates at the various given values, remember that x is time and y is height.
- If you are given time, then look at the y-value for height
- If you are given height, then look at the x-value for the time.
