Subtract 2F2Csixteen -92sixteen =

UkoKoshka [18]

Choice-'B' is the correct choice . . . 2E9A .

I began converting the original numbers to decimal (base 10),
but decided that 5 points are not worth that much aggravation.

At that point, I wondered whether I could just write it down and
do it like any old other subtraction exercise. I've never done
that before with hex numbers, but I found that I could !

The only place you have to be extra careful is in the third place,
where you have to subtract '9' from '2'. In order to do that, you
have to borrow one from the 'F'. That makes the 'F' an 'E', and
it makes the '2' an '18', from which you can then easily subtract
the '9'. The difference of '2E9A' then jumps right out.

Thank you. I never knew you could just do that.

What is -4(-4+3)+2 squared. use order of operations.

sineoko [7]

To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.

Answer:

Here, F = 2.911

F > 2.739502 , so reject null hypothesis ( H0)

There is ample evidence to indicate a disparity in the means for the different forms of mails.

Step-by-step explanation:

Null hypothesis - H₀: μ₁ = μ₂ = μ₃ = μ₄

Alternative hypothesis - H₁: At least one mean is different.

df1 is factor degree of freedom and df2 is error degree of freedom.

Decision rule - Reject H₀ if F > F₀.₀₅, (df1, df2)

F0.05, df1,df2 is f critical value at \alpha = 0.05

Here df1 = 3 , and df2 = 68

Using Excel,

F₀.₀₅, ₃, ₆₈ = FINV( 0.05, 3 , 68 ) = 2.739502302

So reject H0 if F > 2.739502

Here, F = 2.911

F > 2.739502 , so reject null hypothesis ( H0)

There is ample evidence to indicate a disparity in the means for the different forms of mails.
