Answer:
11
Step-by-step explanation:
1) lets get rid of the parentheses, we dont really need them:
−22 −4 + 8+ 52 + 2 − 25
Following order of operations we need to work from left to right
so
-22-4=-26
-26+8=-18
-18+52=34
34+2=36
36-25=11
the answer is 11
hope this helps
Answer:
(a)
Conservative
(b)
Not conservative
(c)
Conservative.
Step-by-step explanation:
(a)
Notice that
and
Therefore the field is conservative.
(b)
Notice that
and
but
Therefore is not conservative.
(c)
Notice that
To prove that the vector field is conservative you have to compute the curl of the vector field and you would get that.
Therefore your vector field is conservative.
By converse of isosceles triangle theorem, 5x+5=7x-1
5x+5=7x-1
-5x+5x+5=7x-5x-1
5=2x-1
5+1=2x-1+1
6=2x
6/2=2/2x
X=3
AC=6x+7 when x=3
6x+7=6 (3)+7=18+7=25
AC=25
Answer:
We can conclude that the difference between the two means are between -0.223 and 0.988.
And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.
Step-by-step explanation:
For this case we have the following interval for the difference between Silver Queen - Country Gentlemen:
We can conclude that the difference between the two means are between -0.223 and 0.988.

Answer:
You got them both right, no other choices need to be selected.
Step-by-step explanation:
Both the choices you have put yes to, will give an answer equal to 32.
Since they want us to find the full amount of students in his class, and 20 is 4 more than half the class 20-4=16 and then 16 x 2 is 32
1/2m+4=20 is correct because, if you move the 4 across the equal sign it become a negative and will be subtracted from the 20 therefore becoming 16. 1/2m=16. Now left with only the 1/2m we must multiply by 2 because 1/2 is a fraction and mutipliting it by 2 will allow us to get 1/2 to equal 1 and m by itself.
1/2m*2=1m
1m=16*2 Keep in mind you must do the same to both sides so the 16 is multiplied as well.
4th option: Same thing different order
Just send 1/2m over equal sign and 4 over the equal sign to trade places. and you will have 1/2m=16
