A.4d+$13.00-$6.00=$13.20 is your answer.

The reason for this is : 

Step One : Start with what you know
($13.00-$6.00)

Then make a full equation based on what you need to find out.($7.00+4d)/4=(13.20)/4              
Start simplifying.
(1.75+d)-1.75=(3.3)-1.75
Continue to simplify for your answer.
d=1.55
1.55 is the answer.

sladkih [1.3K]

Answer:

1.691

Step-by-step explanation:

Standard error of the mean is expressed as SEM = S/√n

S is the population standard deviation

n is the sample size (number of observation)

Given S = 27 and n = 255

SEM = 27/√255

SEM = 27/15.97

SEM = 1.691

Hence the standard error of the mean is 1.691

Negative × positive = negative

positive ÷ negative = negative

negative ÷ positive = negative

positive x negative = negative

Note: when the signs are different, they will give negative

When the signs are the same, they will give positive
