Hello please your question is in-complete attached is the complete question
degree of freedom = -62.90 ( e )
Step-by-step explanation:
The formula for calculating the F-statistic/test statistic is
test - statistic = Coef ( LBW) / SE Coef ( LBW )
= -0.72399 / 0.01151
= - 62.90
the degree of freedom the F-statistic has = -62.90
F-statistic test is any statistical test in which the test statistic has an F-distribution under the null hypothesis. the value of the test can be gotten from running an ANOVA test or regression analysis on the statistical models
Step-by-step explanation:
#1 equals 1 1/4
The common denominator for 1/6, 2/3, and 5/12 would be 12. So I made the denominators 12 which means 1/6 would turn into 2/12, 2/3 turns into 8/12, and 5/12 stays the same. When I add them all up I get 15/12. I can turn that into a mixed number which would be 1 3/12. I can simplify that down to <em><u>1 1/4.</u></em>
#2 equals 3/4
The first thing you have to do is turn 2 2/3 and 1 3/4 into improper fractions. Which would turn 2 2/3 into 24/3 and 1 3/4 into 21/12. The next thing is you have to find a common denominator which would be 12. Next you have to turn the denominators into a 12 and change the numerator. Which makes the fractions: 24/12, 6/12, and 21/12. When you add 24/12 and 6/12 together you get 30/12 minus 21/12 you get 9/12. You can then simplify that to <em><u>3/4. </u></em>
#3 equals -1 17/36
The first thing you do is turn 3 5/18 into an improper fraction which would be 59/18. then you find a common denominator which would be 36 and make the denominators of those numbers into 36 which would be 11/36, 54/36, and 118/36. When you add up 11/36 and 54/36 you get 65. but when you - 65 by 118 you get -53 / 36. you can lend turn that into <u>-</u><em><u>1 17/36. </u></em>
I'm not sure about number 4 and I don't want to give you the wrong answer. Hopefully what I did show you helped!
Answer: Option 'B' is correct.
Step-by-step explanation:
Let the initial concentration be

Let concentration after t= 90 hours be N
Since we have given that Sodium-24 has a half life of 15 hours i.e.

So, According to question,

As we know that

Hence, Option 'B' is correct.
Answer:
72
Step-by-step explanation:
This shape is a prism; it's a 3-D shape with 6 sides. Basically, it's a box.
All 6 sides are rectangles.
Surface area means that we'll find the area of all 6 rectangles and add them up.
There's a front and back, left and right, and a top and bottom.
The area of a rectangle is length×width or base×height.
The front and back are identical.
Area = length×width
Area = 6×3 = 18
Since the front and back are the same, two of the rectangles have area = 18.
The left and right are the same:
Area = 3 × 2
Area = 6
Two faces have area = 6.
The top and bottom are the same.
Area = 6 × 2
Area = 12
Again, two faces have area = 12.
To find the total surface area, add up all 6 areas.
A =18+18+6+6+12+12
A = 72
