Answer: 1
Step-by-step explanation: first you need to pretend that the absolute value bars are parentheses. Then substitute a with any number less that five, for example z=3
Now we can write our new equation: (3-6)-(3-5) now we have to determine if the final answer inside the parentheses is positive or negative. In the first parentheses 3-6=-3 with is negative. In our second parentheses we have 3-5=-2 which is a also negative.
Knowing that both parentheses are negative results we can set up an equation using z instead of 3:
-(z-6)-(-(z-5)) is our new equation. If we simplify this equation we get 1 for an answer
Area of a triangle is,
Substitute the numbers,
The above number is the base.
Using the pythagorean method let's calculate for "c" the hypotenuse.
Substitute
Solve,
Simplify,
Calculate one last time,
The hypotenuse is 37 inches.
Answer:
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
Step-by-step explanation:
Given that the head of institutional research at a university believed that the mean age of full-time students was declining. In 1995,the mean age of a full-time student was known to be 27.4 years.
For this he has recorded all 4934 students and got average as 27.1 years
This is very much perfect because the question is about the mean age of a full time student. when all full time students in the university are taken into account and mean arrived this is a reliable procedure.
The hypothesis also is right as this is left tailed test.
Since p =0.002<0.05 he rejected null hypothesis.
Conclusion is the mean age did decline. Everything is right.
A. No, the hypothesis test was conducted correctly, and the correct conclusion was made.
