Answer:
D. 24
Step-by-step explanation:
To find the perimeter, you add the measurement of each side. The measurement for each side is 6 square cubits.
There are 4 sides so 6+6+6+6=24 square cubits
Let x = the unknown number to get x = 6
Answer:
y = mx + c
m = -4
at y intercept x = 0
(x,y) =(0,-3)
-3 = -4(0) + c
c = -3
therefore the answer is y = -4x + c
20+20=40*.1 (10%) =4
40-4=36
Answer:
1.16 to 2.75
Step-by-step explanation:
The mean salary (millions of dollars) for shortstops was 1.95.

The population mean for all baseball players was 1.85

The population standard deviation was 1.61.

Formula of confidence interval :
to 
z at 95% confidence level = 1.96
Substitute the values in the formula
Confidence interval :
to 
Confidence interval : 1.16 to 2.75
Hence the 95 percent confidence interval for these data is 1.16 to 2.75
