As per given description, we have
Population proportion : 
Sample size : n= 500
Sample proportion : 
Test statistic for population proportion :-

Hence, the test statistic for this hypothesis test for a proportion= -1.78
Area of the box:
A = 2 a² + 4 a h = 600 cm²
h = a ( the box is a cube )
A = 6 a² = 600 cm²
a² = 100
a = 10 cm
V = a³ = 10³ = 1000 cm³
Answer: No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Answer:
Step-by-step explanation:
chris is 11 5/6 years old
marian is 1 1/3 years younger...
(11 - 1) = 10 : (5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2)...so marian is 10 1/2
jane is 1 1/4 years younger then marian...
10 1/2 - 1 1/4...
(10 - 1) = 9 : (1/2 - 1/4 = 2/4 - 1/4 = 1/4)....so Jane is 9 1/4 years <==
