Lacey, because you have to do the opposite when you want to get rid of a number. She subtracted 20 because it was originally positive 20. Chris messed up and did not do the opposite, subtraction, and instead he added 20
Answer:
Step-by-step explanation:
Concept Used: Percentage: 
I think the correct answer would be B. The graph in the attached image would most likely be described as a bimodal symmetric. A bimodal graph would be a graph which has two peaks. From the image, we have 3 peaks so it should be a multimodal but it is not in the choices the closest would be a bimodal one. Each group of the peak shows a symmetrical distribution since the left side and the right side are almost mirrors of each other which is seen for all the three peaks. So, the graph should be a bimodal symmetric distribution.
Answer:
A) 0.20
B) 0.06
Step-by-step explanation:
From the question above we have the following information;
30% of the residents of a particular town read the morning paper
Probability (of the residents that read morning paper) = 0.3
25% read the afternoon paper
Probability (of the residents that read afternoon paper) = 0.25
10% read both
Probability (of the residents that read both) = 0.10
A. One resident is randomly selected. What is the probability that this person reads only the morning paper?
Probability( that this person reads only the morning paper) = Probability (of the residents that read morning paper) - Probability (of the residents that read both)
= 0.30 - 0.10
= 0.20
B. Given that a random resident reads the morning paper, what is the probability that this resident also reads the afternoon paper?
Probability( that this resident also reads the afternoon paper) = Probability (of the residents that read morning paper) × Probability (of the residents that read afternoon paper)
= 0.30 × 0.20
= 0.06
Answer:
x = -5/7, 2
Step-by-step explanation:
Step 1: Factor
(5x + 7)(x - 2) = 0
Step 2: Find <em>x</em> roots
5x + 7 = 0
5x = -7
x = -5/7
x - 2 = 0
x = 2
