Answer:
n=9
And replacing the info we got:
So then the correlation coefficient would be r =0.1955
Step-by-step explanation:
Data given
Temperature (x) 62 76 50 51 71 46 51 44 79
Growth (y) 36 39 50 13 33 33 17 6 16
Solution
The correlation formula is given by:
For our case we have the following sums:
n=9
And replacing the info we got:
So then the correlation coefficient would be r =0.1955
Multiplying these together, we get:

The square root of x^2 is x, so we have a final expression of 4x.
X = <span>weight of the baby.
y = </span>weight of the doctor.
z = weight of the nurse.
x + y = 78 so y = 78 - x
x + z = 69 so z = 69 - x
x + y + z = 142
substitute y = 78 - x and z = 69 - x into x + y + z = 142
x + y + z = 142
x +78 - x + 69 - x = 142
-x + 147 = 142
-x = - 5
x = 5
answer
<span>the weight of the baby was 5 kg</span>
Answer:
Reflect the parent function over the x-axis, and translate it 8 units to the left.
Step-by-step explanation:
The given function is

The parent function is

Since there is a negative multiply the transformed function, there is a reflection in the x-axis.
Since 8 is adding, within the square root, there is a horizontal translation of 8 units to the left.
Therefore to graph the given function, reflect the parent function over the x-axis, and translate it 8 units to the left.
