In this question, you are given the average speed of the car(70miles per hour) and the time of car travel(4.5 hours). The information is enough to find the car travelling distance. The equation would be:
Distance traveled= average speed * duration= 70miles/h * 4.5 h= 315miles
2.5% of the boxes have weights that are more than 2 standard deviations below the mean.
<h3>What is
empirical rule?</h3>
The empirical rule states that for a normal distribution, 95% of the values are within two standard deviations from the mean.
Given mean of 16 ounces and a standard deviation of 0.5 ounces.
Hence:
95% is within 16 ± 2(0.5) = (15, 17)
number above 2 standard deviation = 5%/2 = 2.5%
2.5% of the boxes have weights that are more than 2 standard deviations below the mean.

Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer:
Option 3
Step-by-step explanation:

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute
simplify
The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure
