Assoli18 [71]

Answer: 125/242

Step-by-step explanation: Probability is favorable outcomes over all outcome, since there were 250+234 total outcome, and 250 were favorable (girls), then the probability is 250/250+234=250/484=125/242

Part 1: How's the weather?
mariarad [96]

Answer:

Part 1: How's the weather? Investigate the weather forecast in your city.

Record the high and low temperatures that are forecast for the next 7 days in the table below. In the columns titled, Difference," record the change in temperature from the day before. To do this, subtract the previous temperature from the current temperature Be sure to use positive and negative numbers as needed! For example, if yesterday’s temperature was 70 and today’s temperature was 65, the difference is 65 – 70 = -5.

Note: The columns for Day One's subtraction and difference cannot be filled in. As this is the first data point, there is no previous temperature to subtract.

Write a mathematical expression using the information from your table to answer the following questions:

What is the mean change in the forecaster high temperatures? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.

What is the mean change in the forecaster low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.

Triangle has sides 7 inches, 7.5 inches, and x inches. What is the range of possible lengths for side x, in inches?
jarptica [38.1K]

Answer:

<em>0.5 < x < 14.5</em>

Step-by-step explanation:

<u>Triangle Inequality Theorem </u>

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining those inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given two of the triangle side lengths as y=7.5 and z=7, thus the third side length (x) can be in the range:

7.5 - 7 < x < 7.5 + 7

0.5 < x < 14.5

<u>Note: The latter is the correct answer but none of the choices is accurate. Choice D is closer to the correct answer but the endpoints cannot be included.</u>
