Answer:
The correct statement is
The null hypothesis is 
The alternative hypothesis is 
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.18
The sample size is n = 1240 airplane
The number of airplane is k = 310
Generally the sample proportion is

=> 
=> 
The null hypothesis is 
The alternative hypothesis is 
Answer:
after 75 minutes
Step-by-step explanation:
The least common multiple (LCM) of 15 and 25 is 75. It can be found a couple of ways:
1. List the factors of each number and find the product of the unique ones:
15 = 3·5
25 = 5²
The LCM is 3·5² = 75.
__
2. Find the greatest common divisor (GCD) and divide the product of the numbers by that value. From the above list of factors, we see that 5 is the GCD of 15 and 25. Then the LCM is ...
15·25/5 = 75
__
Or, you can simply list multiples of each number and see what the smallest number is that is in both lists:
15, 30, 45, 60, <em>75</em>, 90
25, 50, <em>75</em>, 100
__
The two buses will appear together again after 75 minutes.
Answer:
b.
24 yd
Step-by-step explanation:
Hi, since we have a right triangle we have to apply the Pythagorean Theorem:, to find the missing side.
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (10 yd) and a and b are the other sides.
Replacing with the values given:
10^2 = 6^2 + b^2
100 = 36+b^2
100-36 = b^2
64 = b^2
√64 = b
b= 8
Now, we can calculate the area:
A =1/2x base x height = 1/2 x 8 x 6 = 24 yd
