Answer:
600
Step-by-step explanation:
10*-5=-50*-4=200*3=600
The answer is 600.
Figure B is misleading because " vertical scale doesn't start with zero"
Step-by-step explanation:
Given are the two bar graphs to compare the sales of two theatres.
The x-axis has types of movies and y-axis has sales.
We can see that the scale of Figure A on y-axis starts from zero while the scale of figure B starts from 50. The both graphs cannot be compared with this scale.
Hence,
Figure B is misleading because " vertical scale doesn't start with zero"

Answer:
Intersect/Solution at (1, -2)
Step-by-step explanation:
Equation 1: y = 3x - 5
Equation 2: y = 6x - 8
Step 1 Mutliply each side of equations one by -2
New Equation 1: -2y = -6x + 10
New Equation 2: y = 6x -8
Add the Equations: -y = +2
Multiply each side by -1 and you'll get that y = -2
Plug in -2 to either equation: -2 = 3x - 5
add 2 to each side 0 = 3x -3
add 3 to each side 3x = 3
divide by 3 and you'll get that x = 1
Answer: (145820, 170180)
Step-by-step explanation:
Formula for confidence interval for population mean ( when population standard deviation is unknown ) :
, where n= sample size
= sample mean
s= sample standard deviation
= two-tailed t-value for significance level of (
).
We assume that the salary of CFA charterholders is normally distributed .
Let x represents the salary of CFA charterholders .
As per given , we have
n= 36
Degree of freedom : df = 35 [ df= n-1]
s= $36,000
Significance level : 
Using t-distribution table ,
95% confidence interval for the average salary of a CFA charterholders :-
Hence, the 95% confidence interval for the average salary of a CFA charterholder : (145820, 170180)
