Answer:

Rise=2 Run=1 type of slope is positive slope is 2 y int is 1 and the equation is y=2x+1

Step-by-step explanation:

1. First you need slope, slope is y1-x1/x2-y2 so then you get 4/2 which is 2, we also know rise/run so rise is 2

2. 2/1 so run is 1

3. its positive since slope is positve

4. y int is when x is 0 and y has value so y int is 1

5. y=2x+1 since slope and y int

Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 50.7 d

Svet_ta [14]

Answer: The mean of the frequency distribution is 51.7°.

The computed mean 51.7° is greater than the actual mean 50.7° .

Step-by-step explanation:

The given table :

Low Temperature (°F) Frequency Mid -value

Class interval f x fx

40-44 2 42.5 85

45-49 7 47.5 95

50-54 9 52.5 105

55-59 5 57.5 115

60-64 1 62.5 25

$\text{Now, Mean}=\dfrac{\sum fx}{\sum f}\\\\=\dfrac{85+332.5+472.5+287.5+62.5}{24}\\\\=\dfrac{1240}{24}=51.6666666667\approx51.7$

The computed mean 51.7° is greater than the actual mean 50.7° .
