Answer:

option A is correct

hope it helps :)

Step-by-step explanation:

The Standard Deviation Rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean. It states that

68% of data falls within the first standard deviation from the mean.

95% fall within two standard deviations.

99.7% fall within three standard deviations.

Therefore, looking at the options, the true statement id

Find the coordinates of the midpoint of TU for T(3,1) and U(5,3)
bixtya [17]
<h3>Answer:  (4,2)</h3>

==========================================================

The given points are T(3,1) and U(5,3)

The x coordinates of these given points are 3 and 5. Add them up to get 3+5 = 8. Then cut this in half getting 8/2 = 4. This is the x coordinate of the midpoint.

The y coordinates are 1 and 3. They add to 1+3 = 4. Then that cuts in half to get 4/2 = 2. This is the y coordinate of the midpoint.

The midpoint is (4,2)

Effectively, we just used the midpoint formula

(x_m, y_m) = \left( \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} \right)

In short: add the corresponding coordinates, then divide by 2.

In 3 hours a car traveled 180 kilometers. At the same average rate, how many kilometers can the car travel in 5 hours?
arlik [135]

Answer: 5 hours = 300 Kilometers

Step-by-step explanation: If a car can travel 180 kilometers in three hours then in one and a half hour that car can travel 90 kilometers. If you divide 90 by 3 you will find out that in a half hour that car can travel 30 kilometers. So add 180+90+30=300 that is the same as adding three hours+one and a half+thirty minute=five hours

Hope This Helps!!!!!

What is the range if the function in this table?
Lana71 [14]

The range of a function is the set of y-values the function contains. Thus, in this case, the range would be the set of values under the y column, as this represents the y-values the function produces.


We see "2, 3, 4, 2" under the y column. Since we are establishing a set of values, we are going include all the values under the column, which includes 2, 3, and 4. We are <em>not </em>going to repeat the second 2 because it isn't necessary, as 2 is already in the set thus.


Thus, the final set for the range of the function is {2, 3, 4}, or Choice A.
