m = 4, p = 4
Note that when two variables are placed directly next to each other, you are multiplying
plug in 4 for both m and p
(4)(4) + 4
Multiply
4 x 4 = 16
Add
16 + 4 = 20
20 is your answer
hope this helps
Answer:
B)
Step-by-step explanation:
In statistics, an outlier is a data point that differs significantly from other observations.
This can happen because of different reasons: it may be due to variability in the measurement or it may indicate an actual experimental error. If it is an actual experimental error then it can create problems when doing the statistical analysis.
A) We can say that this is true, the outliers are observed values far from the other data, however we can make a much deeper analysis of this.
B) This is the right answer, since we don't know what is really causing the outlier, we need to take a closer look to see if they are just mistakes (and therefore be removed). If they are not mistakes we need to do the analysis with and without them to reach correct conclusions.
C) this is wrong because although the part of the histogram is true. It is not true that they should be ignored.
d) The outliers differ significantly from the other data but this doesn't make them the minimum and maximum values in a data set and therefore they should not be treated as such.
Therefore, the correct answer is B)
Answer:
Therefore the rate change of distance between the car and the person at the instant, the car is 24 m from the intersection is 12 m/s.
Step-by-step explanation:
Given that,
A person stand 10 meters east of an intersection and watches a car driving towards the intersection from the north at 13 m/s.
From Pythagorean Theorem,
(The distance between car and person)²= (The distance of the car from intersection)²+ (The distance of the person from intersection)²+
Assume that the distance of the car from the intersection and from the person be x and y at any time t respectively.
∴y²= x²+10²
Differentiating with respect to t
Since the car driving towards the intersection at 13 m/s.
so,
Now
= -12 m/s
Negative sign denotes the distance between the car and the person decrease.
Therefore the rate change of distance between the car and the person at the instant, the car is 24 m from the intersection is 12 m/s.
Answer:
It is actually less than 10.
