The two consecutive whole numbers that lies between the square root of 17 is 4 and 5
Isolate the variable by dividing each side by factors x = 148/203
Answer:
The teacher select a sample of n =15 students. And he wanted to know if teaching a smaller class was more effective and students performed better, that means if
and he obtaind a sample mean of
.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis: 
And the best option for this case is:
a. H0:
vs. H1:
.
Step-by-step explanation:
For this case we have the following previous info given:
represent the true mean
represent the true deviation

So for projectile motion questions, we use the Cartesian equations.
Given that s(t) is the height of the projectile at an arbitrary time, t, we want the height of the projectile to equal to zero in order to find its flight time.
Let s(t) = 0.

Now, the initial velocity of the projectile is given to be 19.6, and the initial height is 24.5.
Substitute those in to find:
