Answer:
x= -1
Step-by-step explanation:
8x - 16 = -4x - 4(1-6x)
8x - 16 = -4x - 4+24x
8x - 16 = 20x-4
8x - 16+16 = 20x-4+16
8x = 20x+12
8x-20x = 20x-20x+12
-12x=12
Divide both by -12, and you get -1.
16 blocks = 4 steps
x blocks = 50 steps
(16 blocks x 50 steps)/4 steps
= 200 blocks
Answer:
- The variation in the sample means makes it possible to make predictions about the population mean.
- The actual population mean is greater than 236.
- The actual population mean is less than 245.
Step-by-step explanation:
<u>Sample data</u>
- 1 2 3 4 5 6
- 240 236 245 243 238 242
<u>Mean = sum of sample data/sample frequency</u>
- (240+236+245+243+238+242)/6 = 240.67
Answer choices:
The variation in the sample means makes it possible to make predictions about the population mean.
The actual population mean is greater than 236.
The actual population mean is less than 245.
The actual population mean is greater than 245
The population mean is the average of the sample means.
