That's the way I answer in my country but I'm not sure about this solution is correct in your school or not.
Answer:
D
Step-by-step explanation:
![( {2 x})^{ \frac{1}{3} } - 7 = \sqrt[3]{2x} - 7](https://tex.z-dn.net/?f=%28%20%7B2%20x%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20-%207%20%3D%20%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%207)
Answer:
Step-by-step explanation:
Then the x part of the point takes on the opposite sign that it currently has.
- Right now it is 1. If it takes on the opposite sign, it becomes - 1
- So the new point is (-1,-5).
- Nothing happens to the - 5 when reflected across the y axis.
Answer:interquartile range IQR
Step-by-step explanation:ApE x
We get the cumulative frequency as:
3
7
13
22
29
36
37
We are given the data:
Daily Low(°F) Frequency
35 - 39 3
40 - 44 4
45 - 49 6
50 - 54 9
55 - 59 7
60 - 64 7
65 - 69 1
We have to find the cumulative frequency of the data.
We will do this by adding the data values of previous interval.
Daily Low(°F) Frequency cumulative frequency
35 - 39 3 3
40 - 44 4 7
45 - 49 6 13
50 - 54 9 22
55 - 59 7 29
60 - 64 7 36
65 - 69 1 37
Therefore, we get the cumulative frequency as:
3
7
13
22
29
36
37
