Answer:
y=-9x-38
Step-by-step explanation:
In slope intercept form we know that the equation for a line is given by
y=mx+b, Where m is the slope (which we have and is -9) and b is the 'y' axis intercept point.
Lets use the given point (-4,-2) to find b
y=-2 and x=-4
-2=-9*-4 +b
We have b=-38

Answer: 71 children ate hotdogs at the picnic.
Step-by-step explanation:
Given: About 32% of the 104 children who ate a school picnic ate hamburgers.
The number of children ate hamburger = 32% of (104 children)
= 0.32 x 104
= 33.28 ≈ 33
Thus, the number of children ate hamburger = 33
Number of children ate hotdogs = 104-33 = 71
Hence, 71 children ate hotdogs at the picnic.
Answer:
160 ft
Step-by-step explanation:
the length of one side would be √1600 which is 40 so 40• 4 is 160
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.
