Step-by-step explanation:
hi!
area:
both 7 by 4 sides: (7*4)2=56
both 3 by 7 sides: (3*7)2=42
both 3 by 4 sides: (3*4)2=24
add em up=56+42+24=122
i hope this answered your question. let me know if i missed something and ill fix it!
The linear equation represents y = mx + b describes several real world situations such as
- Relation between printer and ink cartridges,
- Relationship between number of songs and how much is left on the card.
<u>Step-by-step explanation</u>:
Linear equations y = mx + b.
m is your rate of change.
b is your constant. This is the initial value of y. The value of y when x is 0.
Finally, y is the thing that depends on x.
Oh right, examples:
- I buy a printer for $100 and the ink cartridges cost $25 each. The relationship between ink cartridges and total cost.
total cost = 25(cartridges I buy) + 100 or y = 25x + 100
-
I get a $100 iTunes gift card for my birthday and then start buying $1 songs. The relationship between the number of songs I buy and how much is left on the card
amount left on card = -$1(songs bought) + 100 or y = -x +100
Answer:
Step-by-step explanation:
Information given
represent the sample mean for the sample
population mean (variable of interest)
s=4.9 represent the sample standard deviation
n=8 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
the degrees of freedom are given by:
Since the Confidence is 0.95 or 95%, the value of 
and 
, and the critical value for this cae would be 
Now we have everything in order to replace into formula (1):
