Answer:
Null hypothesis: 
Alternative hypothesis :
C. The mean Rutgers College GPA has increased to more than 3.15
Step-by-step explanation:
Data given and notation
represent the average score for Rutgers College in 2000
represent the average score for Rutgers College in 2002
represent the sample standard deviation in 2000
represent the sample standard deviation in 2002
sample size
State the null and alternative hypotheses. .
What are H0 and Ha for this study?
Null hypothesis:
Alternative hypothesis :
For this case we need to take in count that the alternative hypothesis can't have and = sign, and based on the information a good hypothesis here would be if the average GPA increased between 2000 and 2002, so based on this the best option for this case would be:
C. The mean Rutgers College GPA has increased to more than 3.15
the percentage is 75%
because 90 divided by 120 is 0.75.
Answer:
In order to do so, we need to use basic algebra. The angles in a kite add up to 360 degrees. so we form the following equation.
x + y + y + 16 = 360
x + y + y = 344 <----(360 -16)
Each letter or variable represents an angle measure. the measures of the three angles left. The 16 degrees is on the bottom of the kite and the angle opposite is the top angle. the two side angles will be the same measure that's why they are both y.
x + 2y = 344
The two side angles will be 90 or greater because there is only 1 acute angle. 90 is the smallest number that can be chosen. so we do the following.
Step-by-step explanation:
x + 2(90) = 344
x + 180 = 344
x = 344-180
x = 164
THE MAXIMUM WHOLE NUMBER MEASURE OF THE ANGLE OPPOSITE OF THE 16 DEGREE ACUTE ANGLE IS 164 DEGREES*
125 dollars a week he would have by an average I did theis yesterday XD
We are asked to d<span>etermine the area under the standard normal curve that lies to the left of the following z score of 1.57. in this case, we can use the rules of integration as this is related to area under the curve:
