Answer:
is 5 point worth it ummm no
Step-by-step explanation:
Answer:
The P-value for this test is P=0.00006.
Step-by-step explanation:
We have a matched-pair test, with a test statistic t=-14.9.
The degrees of freedom in a sample of 5 students is:

For a t=-14.9 and 4 degrees of freedom, a left-tail test will have a P-value of:

The claim is that the new unit on taking square roots is helping students to learn. This test concludes that there is statistical evidence to support the claim that the new unit is helping students to learn.

Define x :
------------------------------------------------------
Let the width be x.
------------------------------------------------------
Find Area of the walkway :
------------------------------------------------------
Area = 30x + 30x + 20x + 20x + 4x²
Area = 100x + 4x²
------------------------------------------------------
Find cost of the walkway in term of x:
------------------------------------------------------
1m² = $10
100x + 4x² = 10(4x² + 100x)
(100x + 4x²)m = $(40x² + 1000x)
------------------------------------------------------
Find Width of the walkway :
------------------------------------------------------
The budget is $6000
40x² + 1000x = 6000
40x² + 1000x - 6000 = 0
x² + 25x -150 = 0 //Divide by 40 through
(x - 5)(x + 30) = 0 //Factorise
x = 5 or x = -30 (Rejected, width cannot be negative)
------------------------------------------------------
Answer: The width can be 5m wide.
