=3x^2+4
Step-by-step explanation:
Subtract 8 from 12.
3x^2+4
Answer:
9.75
Step-by-step explanation:
1.65 x5 is 8.25 then you add half of 1.65 which is .825 to get 9.75
Answer: x=15
Explanation: you can set 2x+100 = 5x+55 because they are corresponding interior angles.
Work:
2x+100 = 5x+55
2x+100-5x = 55
2x-5x = 55-100
-3x = -45
divide by -3 to cancel the negative and get x by itself
x = 15

To determine the rate that an individual walks. Take each set values and put in the following formula to solve for the rate.
Rate = number of feet/ seconds
Person 1 = 60 feet / 10 seconds = 6 feet/sec
Person 2 = 25 feet / 5 seconds = 5 feet/second
Person 1 walks at a faster rate than person 2.
The average score is 500 points and the standard deviation is 50 points.Mean - 2 SD = 500 - 2 * 50 = 500 - 100 = 400It means that more than 400 on the standardized test is more than: Mean - 2 Standard deviations.For the Normal distribution: 100% - 2.5 % = 97.5% = 0.975.Answer: The probability that student scores more than 400 points is 0.975.
