It would just be -3>-5 and 3+2=5. This symbol (<span>^) simply means and.</span>
Answer:
The graph is included in the attached pictures
Step-by-step explanation:
The graph for y=4-|x| is shown in the attached picture, the inequality tell us that the region is located below that particular graph including the function, hence you have the second attached picture
Using the normal distribution, there is a 0.1587 = 15.87% probability that’s a car picked at random is traveling at more than 100 km/hr.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The probability that’s a car picked at random is traveling at more than 100 km/hr is <u>one subtracted by the p-value of Z when X = 100</u>, hence:
Z = 1
Z = 1 has a p-value of 0.8413.
1 - 0.8413 = 0.1587.
0.1587 = 15.87% probability that’s a car picked at random is traveling at more than 100 km/hr.

4. Think about it, it would mean that 4 is the result of 0.4 (40%) multiplied by a number. Therefore, you would divide 4 by 0.4. The answer would be 10.
5. To do this, multiply 0.2 by 700. This gives you 140.
6. Think about it, what percent of 25 is 12. Divide 12 by 25, then multiply by 100 and add a percent sign after it. 12/25 is 0.48. Multiply that by 100 to get 48%.
Answer:
48 mph
Step-by-step explanation: Add 42mph and 54 mph and you get 96. To find the average of the two --- divide 96 by 2 and you get 48mph as the average speed for the entire trip.
