Answer:
40/m
Step-by-step explanation:
I dont really know what I'm answering but there's that
|-80|=80
|x| -≥ this symbol is named as mod
we use this to find the absolute value...
it can be explained easily as meaning like rounding off
I'm that even the number given inside in negative we should write the answer only in positive
negative number can never be the answer of absolute value
hope helpful

Answer:
The p value for this case would be given by:
Since the p value is higher than the significance level provided we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly less than 20 ounces.
Step-by-step explanation:
Information provided
represent the sample mean
represent the population deviation
sample size
represent the value that we want to test
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is at least 20 ounces, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
The p value for this case would be given by:
Since the p value is higher than the significance level provided we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly less than 20 ounces.
It doesn’t really matter which variable you isolate first but usually you would use the one that’s by itself already. like for example one of the equations was y = 8. you would already have your y solve for so you would just have to plug that in for y in the other equation. personally, i usually do x first unless one of the equations has either x or y by itself already. i think its easier to just do x first and then solve for y after that, but it just depends on what the equations are; sometimes it might be easier to just do y first. hope this helps!
Solution
One centimeter is equal to 10 millimeters. To find how much millimeters are in 46 centimeters you have to multiply by 10 since there are 10 millimeters in 1 centimeter .
1 cm = 10 mm
Calculations
46 x 10 = 460
There are 460 millimeters
46 cm = 460 mm
