Given : A random sample of 700 home owners in a particular city found 112 home owners who had a swimming pool in their backyard.
i.e. n= 700 and x= 112
Sample proportion : 
z-value for 95% confidence interval : 
Now, the 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard will be :-
Hence, 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard :
Answer:
x = 113
Step-by-step explanation:
The corresponding angles in both triangles are congruent
Hence x = 113
Answer:
its d
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Given
4(x - 5) = 8x + 4 - 6x ← distribute left side and simplify right side
4x - 20 = 2x + 4 ( subtract 2x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer:
If a = 5 and b = 3, then that means 2a - 3b + 3a = 16
Step-by-step explanation:
2a - 3b + 3a
(2×5) - (3×3) + (3×5)
10 - 9 + 15 = 16
