Ee a solution process below:
Explanation:
The point-slope formula states:
(
y

)
=
m
(
x

)
Where
m
is the slope and
(
x

y
1
)
is a point the line passes through.
Substituting the slope and values from the point in the problem gives:
(
y

)
(
y

Answer:
4 bags
Step-by-step explanation:
The way to read a step and leaf diagram is to consider the "stem" as the tens digit and "leaf" ans the ones digit.
So "0" in stem and "5" in leaf would be the number "05" or simply "5"
Also, "2" in stem and "4" in leaf would be the number "24"
When we have more numbers in leaf, they are basically different numbers. So lets list the numbers from stem-and-leaf plot:
5, 24, 30, 34, 65, 70, 74, 87, 90
The question asks for how many numbers are there LESS THAN 40?
the numbers less than 40 are:
5, 24, 30, 34
That is 4 numbers
4+3=7+3=10+3=13. Steps.........
Ninth term in the sequence is 30
Answer:
6.650, 6.68, 6.803, 6.82

Answer:
Method 1 has bigger forecast bias.
Step-by-step explanation:
We are given the following information in the question:
Actuals:
23, 10, 15, 19
Method 1 prediction:
23, 5, 14, 20
Residuals = Predicted - Actuals
Sum of square of errors:

Mean squared error:

Method 2 prediction:
20, 13, 14, 20
Residuals = Predicted - Actuals
Sum of square of errors:

Mean squared error:

Since, mean square error of method 2 is less as compared to method 1, method 1 has bigger forecast bias.
