Answer:
See answers below
Step-by-step explanation:
T59 = a+58d = -61
T4 = a+3d = 64.
Subtract
58d-3d = -61-64
-55d = -125
d =125/55
d = 25/11
Get a;
From 2
a+3d = 64
a+3(25/11) = 64
a = 64-75/11
a = 704-75/11
a = 629/11
T23 = a+22d
T23 = 629/11+22(25/11)
T23 = 1179/11
We simply divide the mass of Saturn with the mass of Earth.
5.686 x 10^26 / 6.04 x 10^21
The rule of significant figures when dividing numbers is that the least amount significant figures must be used in the quotient.
Therefore, Saturn is 9.41 x 10^4 times heavier than Earth.
Explanation:
Since we have given that

Now, we have to prove it as

Now, start the iterations:

So, first blank will be filled with

Second blank will be filled with

Hence proved.
6.5m = __0.0065__km
To calculate a value in meters to the corresponding value in kilometers, just multiply the quantity in meters by 0.001<span> </span>
Answer and explanation:
Given : Examination of court records in a particular state shows that the mean sentence length for first-offense drug dealers is 26 months with a standard deviation of 2 months. The records show that the sentence lengths are normally distributed.
i.e. Mean
, Standard deviation 
Using Z-score formula,

1) What is the Z score for a 23 month sentence length? What is the probability of getting a sentence below that?
The Z score value for a
is given by,



The probability of getting a sentence below that is 
i.e. 

2) A defense attorney is concerned that his client's sentence was unusually harsh at 30 months. What percent of sentences are 30 months or longer? Calculate the Z score and report the area.
The Z score value for a
is given by,


The probability of getting a sentence below that is 
i.e. 


Into percentage, 
3) Would you consider a 30 month sentence harsh? Explain
Since the percentage for 30 months or greater is harsh because the smaller value of percentage of
