The ratio of width to length will be the same so
4/7 = 16/l
l = (7*16) / 4 = 7 * 4 = 28
length = 28 inches
Answer:
Ntoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00.
This in real becomes :
dollars
But, Tess says, "It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20
So, Tess is wrong. Rather she should have done 10% of $46 giving $4.6 and then half of 4.6 that is 2.3 dollars. Getting a total of dollars which is the real amount.
The segments AE, EC, AD and DB are in proportion.
Therefore we have the equation:
AE = 4ft, AD = 8ft and BD = 2ft. Substitute:
<em>multiply both sides by 2</em>
Answer:
Part A: YES, it is.
Part B: the amount of pumpkin picked and the amount of fertilizer applied.
Step-by-step explanation:
Part A:
The closer the correlation coefficient is to 1, the stronger the relationship between two variables, and vice versa. Also, the closer the data points are on a scatter plot, the closer the correlation coefficient is to 1.
The scatter plot shown indicates a positive correlation between number of days and number of pumpkins. However, the data points are to some extent farther apart from each other. This shows a moderate relationship between the two variables. Therefore, a correlation coefficient, r, of 0.51 that was calculated can be concluded to be accurate , because an r of 0.51 depicts a moderate relationship between two variables.
Part B:
A variable that could affect the number of pumpkins picked could be amount of fertilizer applied, instead of the day in October. Thus, we can compare the amount of pumpkin picked and the amount of fertilizer applied.
9+18s-7s the common factor is 's' so :
s(18-7) + 9 and that is : 11s+9 The answer is B.
