Answer:
Estimate one digit past the smallest precisely known digit or marking
Step-by-step explanation:
To determine the last digit in any measured number : Estimate one digit past the smallest precisely known digit or marking
This is employed mostly when trying to round off a measured or calculated number to a precise number of digits and in other to determine the last digit in the given number we will have to estimate one digit past the smallest precisely known digit
Answer: a) 6, 0, 10 b) yellow/orange line
Step-by-step explanation:
a) Plug the x in the y functions, y = 2x² + x
when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6
when x = 0, y = 2(0)² + (0) = 0 + 0 = 0
when x = 2, y = 2(2)² + (2) = 8 + 2 = 10
b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.
And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.
Answer:
see the attached
Step-by-step explanation:
<u>Step 1</u>.
The sample size is the number of numbers. There are 10 of them.
n = 10
The mean is the sum of the numbers (1240) divided by the number of them (10).

<u>Step 2</u>.
It is convenient to let a spreadsheet (or calculator) do the math. Enter the numbers and the formulas shown in the table, and let the spreadsheet do the rest.
The formulas for the sample variance and sample standard deviation are given. Fill in the numbers you have so far and do the indicated calculation.
