(1)
And replacing we got:
Step-by-step explanation:
Information given
n=421 represent the random sample taken
estimated proportion of adults that would erase all of their personal information online if they could
is the value that we want to test
z would represent the statistic
Hypothesis to test
We want to check if Most adults would erase all of their personal information online if they could, then the system of hypothesis are :
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
And replacing we got:
Given that the mass of the sun is 2.13525×1030 kilograms, and the mass of Mercury to be 3.285×1023 kilograms. We determine how many times greater the mass of the sun is relative to the mass of Mercury by getting the ratio of their respective masses. With this, we compute the ratio to be 2.13525×1030/3.285×1023 which is equal to 6500000. With this calculation, we can infer that the mass of the sun is 6.5x106 times greater than the mass of mercury.
Answer:
250
Step-by-step explanation:
Let the rope be x meters long
22% of the rope is 55 meters
x *22% = 55
Change to decimal form
x * .22 = 55
Divide each side by .22
x * .22 /.22 = 55/.22
x =250
