Mathematics

Answer:x=1/3

Step-by-step explanation:

5/6-x=1/2

5/6+-x=1/2

-x+5/6=1/2

Step 2: Subtract 5/6 from both sides.

-x+5/6-5/6=1/2-5/6

-x=-1/3

Step 3: Divide both sides by -1.

-x/-1=-1/3/3

X=1/3

Hope this helps

The question mark equals 1/3

Answer:

1/3

Step-by-step explanation:

5/6-?=1/2 so convert 1/2 into sixths so

5/6-?=1/2(3/3) so

5/6-?=3/6 (multiply both sides by 6)

5-5(?)=3 (add 6(?) to both sides)

5=3+6(?) (subtract 3 from both sides)

2=6(?) (divide by 6)

?=2/6 or

1/3

Answer:

The 99 % confidence interval on the basis of mean is ( 21.7393  ;   22.0257)

Step-by-step explanation:

Mean = Sum of observations / Number of observations

Mean = 21.88 +21.76 +22.14 +21.63+ 21.81 +22.12+ 21.97+ 21.57+ 21.75+ 21.96 +22.20 +21.80/ 12

Mean =x`= 262.59/12=  21.8825

Standard Deviation = s= ∑x²/n - ( ∑x/n)²

∑x²/n= 478.7344 +473.4976 + 490.1796+467.8569+ 475.6761 + 489.2944+ 482.6809+ 465.2649+ 473.0625+ 482.2416 +492.84 + 475.24/ 12

∑x²/n= 5746.5689/12= 478.8807 = 478.881

Standard Deviation = s= ∑x²/n - ( ∑x/n)²

s= 478.881- (21.8825)²= 478.881-478.843= 0.037

The confidence limit 99% for the mean will be determined by

x` ± α(100-1) √s/n

Putting the values in the above equation

= 21.8825 ± 2.58 √0.037/12

Solving the square root

= 21.8825 ± 2.58 (0.05549)

Multiplying the square root with 2.58

=21.8825 ± 0.1432

Adding and subtracting would give

21.7393  ;   22.0257,

Hence the 99 % confidence interval on the basis of mean is ( 21.7393  ;   22.0257)

How do I do #1 ? Help!!
juin [17]

1) First find the multiplier.

Look at the 0 and 1st term you have 5 as the 0 and 3 as the 1st term.

2)Ask how do we get from 5 to 3?

  • We subtract 2 so the multiplier is -2

3)Lets make a linear equation: y=mx +b

  • m= multiplier or slope
  • x= Just equals x value
  • b= your starting value or the 0 term which is 5

4)Use the values that you have to create your equation.

  • y=-2x +5

Note:For the x value just plug in the x value from your table.

Ex.

  • y=-2(-10)+5
  • y=20+5
  • y=25
