may you help me solve this? no need for a deep explaintion

Below is a graph of a normal distribution with mean = -4 and standard deviation =4. The shaded region represents the probability of obtaining a value from this distribution that is between - 10 and -2. 0.4- 0.3- 0.2- 0.1- - 10 Shade the corresponding region under the standard normal density curve below. 0.47 0.3- X 5 0.2- 0.1- -9 -8 -7 -6 -5 8Rachel is in charge of planning a reception for 1800 people. She is trying to decide which snacks to buy. She has asked a random sample of people who are coming to the reception what their favorite snack is. Here are the results. Number of People Brownies 28 Favorite Snack -a- Potato chips 72 Other 64 Based on the above sample, predict the number of the people at the reception whose favorite snack will be potato chips. Round your answer to the nearest whole number. Do not round any intermediate calculations. [1] people X f) I? U A carnival spinner has unequal sections labeled 3 through 8. Let A be the number shown on the spinner when it is spun. Here is the probability distribution of A.

The mean of the distribution is 190.3 min and the standard deviation is 19.8 min. In the figure, I is a number along the axis and is under the highest part of the curve. And, U and Ware numbers along the axis that are each the same distance away from V. Use the empirical rule to choose the best value for the percentage of the area under the curve that is shaded, and find the values of U, V, and W.
