Answer:
Option C - 4.71
Step-by-step explanation:
We are given the Test statistic for proportion as;
z = (^p − p)/√pq/n
From the question;
^p = 0.15
p = 0.1
q = 1 - 0.1 = 0.9
n = 800
z = (0.15 - 0.1)/√(0.1 × 0.9/800)
z = 0.05/√(0.09/800)
z = 4.71

Answer: 40
Step-by-step explanation:
Given
Jar contains 200 old dimes
Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes
So, we can write

Answer:
Radius: 7
Diameter: 14
Area Formula: π r^2
Area Answer: 154 ft^2
Step-by-step explanation:
Radius: 14/2 = 7
The radius is always half the diameter.
Area Work
A = π(7)^2
A = π(49)
A = 153.9380 ft^2
Answer:
-740
Step-by-step explanation:
18-72 equals -74
now -74 *10 equals-740
