Answer:
Step-by-step explanation:
By considering the given statements :
Null hypothesis :
Alternative hypothesis : ( opposite of null hypothesis.)
As per given , we have
Sample size : n= 100
Sample mean :
Sample standard deviations :
Since population standard deviation is unknown , so we will perform t-test.
Formula for test statistic ( for population mean):
Hence, the required test statistic :
45 because 36 times 125% is 45
Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°
Answer:
The answer is b
Step-by-step explanation:
Answer:
if you're sating 200 tens(10), then it equals 2000
Step-by-step explanation:
because you'd multiply them, and 200 times 10 equals 2000.
and if you ment 200 ton, the it's 400000. because a ton is 2000, so 200 times 2000 equals 400000
