Answer:
The critical value can be founded in the normal standard distribution table using the value of and we got . Replacing the info given we got:
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the sample mean
represent the sample size
And we want to find the margin of error for a confidence level of 95%. So then the significance level would be and . The margin of error is given by:
The critical value can be founded in the normal standard distribution table using the value of and we got . Replacing the info given we got:
Answer:
2
due to the thenth being higher than the number five i would say round up so 9 becomes a solid number so the answers 2
just remember:
it goes ones decimal tenths hundreths thosenths
as well as five or more raise the score for or less let it rest
sorry for mispelling words its not my greatest skill
Answer:
5x-2y=3
-3x+4y=1
5x-2y=-3x+4y+2
+2y
5x=-3x+6y+2
+3x
8x=6y+2
divide by 2
4x=3y+1
-3y+4x=1
wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same
-3x+4x=1
x=1
y=1
Hope This Helps!!!
The answer to the sunset question is 16 F.
Work Example:
With the number -2, you can order the work simple like these examples over here.
18 + (-2) = 16.
The problem is usually written like this, and here is a little trick. When a positive number is added to a negative number, instead of adding itself, it subtracts the positive form of the negative number with 18, which is our positive number.
18 - 2 = 16.
If you place the -2 as the second number in the equation, the negative works nicely and looks like a minus sign. Or, you can do it in a different way.
