Answer:
50
Step-by-step explanation:
it is given that there is one variable with 1000 records
we have to find the records which is expected would be removed
it is given that one variable is missing with 5% that 0.05
we can find missing records by multiplying total number of records and the missing value with one variable
so the expected record removed will be =0.05×1000=50
Equation: 0.25x + 200
0.25x + 200 = 345
0.25x = 145
140/0.25 = 580 miles
Answer: 580 miles
Answer: y = 5x - 7
Step-by-step explanation:
y = mx + b, where m = slope
We plug in the point, where x = 2, and y = 3
y = 5x - b
3 = 5(2) - b
3 = 10 - b
b + 3 = 10
b = 7
y = 5x - 7
Answer:
The top right graph.
Step-by-step explanation:
If you find the mean for all the graphs you get:
Graph 1: 7 Graph 2: 2
Graph 2: 7 Graph 4: 7
To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:
8 + 8 +8 +8 +8 +8 +1 = 49 Add the data points
49 / 7 = 7 Divide by the total amount of points which is seven
9* 8 2/3
= 9* 26/3
= 3* 26
= 78
The final answer is 78~
