Answer:
9/10
Step-by-step explanation:
There are 20 and 2 green 20-2 is 18 so 18/20 simplified is also 9/10
The perimeter of the triangle is B) 27.4
Please let me know if you need an explanation.
Answer:
28
Step-by-step explanation:
VZ = ZY
2x +2 = 3x -4
6 = x . . . . . . . . add 4-2x to both sides
VZ = 2x +2 = 2(6) +2 = 14
Now we can find VY.
VY = VZ + ZY = 14 + 14 . . . . . . VY is the total of the two halves
VY = 28
Answer:
Option A) 9604
Step-by-step explanation:
We are given the following in the question:
Confidence level = 95%
Standard error = 1%
Formula for sample size:
Putting values, we get,
Thus, the sample size must be
Option A) 9604
Answer:
a) The very first one where the line starts to the left
b) m=125.82
c) 320.81 thousand dollars
Step-by-step explanation:
a) The point on the graph who corresponds to x=3 years and Salary=$200,000 is the very first one where the line starts to the left
b) If a line is given by Y=mx+b, m represents the slope of the line. In this case, m=125.82 which can be interpreted as the rate of growth of the salary per year in thousands of dollars. A doctor can expect to earn 125.82 thousand dollars more than the previous year.
c) If we use the given regression line Y=125.82x-182.47 and make x=4, we get
y=125.82 (4)-182.47 =320.81 thousand dollars
