Answer:
Probability to select a painting will be
Step-by-step explanation:
Art collector is interested in 5 paintings, 6 vases and 2 statues.
We have to find the probability that she selects a painting.
Probability
So total number of outcomes n(S) = 5 + 6 + 2
n(S) = 13
Favorable event n(E) = 5
Therefore, probability to select a painting will be
Answer:
B. 78 and 82.
Step-by-step explanation:
We have been given that the average test score of the class was an 80 and the standard deviation was 2. We are asked to find two values between which 68% of class will score.
We know that in a normal distribution approximately 68% of the data falls within one standard deviation of the mean.
So 68% scores will lie within one standard deviation below and above mean that is:
Upon substituting our given values, we will get:
Therefore, about 68% of the class would score between 78 and 81 and option B is the correct choice.

Step-by-step explanation:
It's (5,7). This is a translation. (x-4) means moving the x coordinate to the left 4 times. If it was positive it would move to the right. (y+15) moves the y coordinate to the right 15 times also would move to the left if negative.
