Since there are no given sample statistics, Let us use the following: n=35, x=24.1, and o=2.7
2-tail test
Using a T-test:
t(24.1) = (24.1-23/[2.7/sqrt(35)] = -2.4103
P - value = 2*P(-100< t < -1.9720, when df = 34)
= tcdf (-100,-2.4103,34) -> using excel
= 0.0107

-10. One type of system of equations that results in infinite solutions is one where both sides of the equation are exactly equal. Here, setting the second equation equal to -10 becomes 2y - 4x = -10. This can be rearranged into 2y = 4x - 10. Dividing everything by 2 results in y = 2x - 5, which is exactly what the first equation is. Substituting one equation into another, we get 2x - 5 = 2x - 5, which is a true statement for all values of x.
Answer:
1/2ft
Step-by-step explanation:
15/28=(5/7)(1 1/2)(w)
15/28=(5/7)(3/2)w
15/28=(15/14)w
(15/28)/(15/14)=w
(15/28)*(14/15)=w
w=14/28
w=1/2 ft
Answer:Should be 200 ft, 100 ft, 200 ft, and 100 ft
