Answer:
For this equation let's round the 3328 to a 3300.
Step-by-step explanation:
If we remove the 2 zeros, we remain with a 33. 33/6 is 5.5 Now if we add back 2 places we get 550. I know this is written badly, but I hope it helped.
Answer:
-3c^2 +6
Step-by-step explanation:
The equation will be an identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combining the c^2 terms.
The contents of parentheses simplify as follows:
... (4c^2 -7c^2 +6) = (c^2(4 -7) +6) = (-3c^2 +6)
So one hour is 60 minutes,
5/6 of an hour would be, 50 minutes. Basically 60/6=10 and 10*5=50
so if the robot does 8 tasks in 50 minutes and each tasks takes the same amount, the equation would be 50/8
50/8= 6.25
Each task is 6 minutes and 25 seconds.
Answer:
4
Step-by-step explanation:
To find the number you have to reverse the equation
Let us call the number "x"
x + 9 = 13
So to find x we flip the equation
13 - 9 = x
Solve it
4 = x
So the missing number is 4
Answer:
d. The population standard deviation is known.
Step-by-step explanation:
T-distribution or Z-distribution, which to use?
If we have the population standard deviation is known, we use the z-distribution.
Otherwise, if we only have the standard deviation for the sample, we use the t-distribution.
Which of the following is not appropriate to use the t-confidence interval for
When the population standard deviation is known, so letter d.
