Answer:
-2
Step-by-step explanation:
The slope of a line tells us how y responds to a change in x. If the slope is 2, it means that for every time x increases by 1, will will go up by 2.
We can calculate slope from a line, or with two given points. I used points (0,4) and (3,-2). Slope is the "Rise/Run."
The Rise: (-2 - 4) = -6
The Run: (3 - 0) = 3
Slope = Rise/Run = (-6/3) = -2
Answer: 709
Step-by-step explanation:
The formulas we use to find the required sample size :-
1. 
, where
= population standard deviation,
E = Margin of error .
z* = Critical value
2.
, where p= prior estimate of population proportion.
3. If prior estimate of population proportion is unavailable , then we take p= 0.5 and the formula becomes
Given : Margin of error : E= 3% =0.03
Critical value for 95% confidence interval = z*= 1.96
A study conducted several years ago revealed that the percent of junior executives leaving within three years was 21%.
i.e. p=0.21
Then by formula 2., the required sample size will be :


[Round to the next integer.]
Hence, the required sample size of junior executives should be studied = 709
The best estimate of the lateral area of the cube with edges that are 2.1 inches long is 4.2
27 pies in one hour
54=2 hours
54 divided by 2 equals 27
