Answer:
3 to the power of 5 is 243 and 3 to the power of 2 is 9 and
243 x 9 is 2187
Step-by-step explanation:
The outlier is 9
Explanation
An outlier is a number that is at least 2 standard deviations away from the mean. For example, in the set, 1,1,1,1,1,1,1,7, “7 “would be the outlier.
Answer:
Bottom left
Step-by-step explanation:
The point of reflection is the bottom left one because when reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line. The fixed line is called the line of reflection.
It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. If a radioactive element decays exponentially at a rate of 0.13% each hour, then the statement that is true is this: <span>If there are 1,000 grams of the element, there will be 756.9 grams in two hours. Hope this helps.</span>
Answer: The velocity of the vehicle at 0 s is 0 m/s
Explanation:
The Velocity vs. Time graph of this situation is shown in the attached image. As we can see, we have five segments:
1) When the vehicle accelerates from 0 to 30 m/s in 10 seconds, which means at 0 seconds the vehicle's velocity was 0 m/s. In addition, as the vehicle goes from zero to a positive velocity, we have a positive slope.
2) Then the vehicle travels for 15 seconds at a constant velocity, that is why we do not have a slope in this section, since the vehicle kept its 30 m/s.
3) The vehicle comes to a stop in the next 5 seconds, that is why we observe an abrupt change in the graph and a negative slope.
4) The car waits 10 seconds in that stop, again we have a line with no slope
5) Finally, the car accelerates from 0 to -10 m/s in the next 5 seconds. This means the car changed its direction.
