Answer:
C. 0.1515
Step-by-step explanation:
The main objective here is to find the P-value for the test of 
Given that ;
the mean value = 2.2
the standard deviation = 1.4
number of recorded accident per week = 52
The null hypothesis is : 
The alternative hypothesis is : 
The Z- value can be calculated as:
z = -1.03
From the normal distribution table for probability;
P(z< -1.03 ) = 0.1515
So to find a cylinder's volume, you do πr^2*h = volume
So we can fill in a few of the elements.
3.14 * 2.5 ^2 * h = 170
And then we can continue to simplify it.
3.14 * 6.25 * h = 170
19.625 * h = 170
And then to find h,
170/19.625 = about 8.66
Answer:
x = .23
x = 1.43
Step-by-step explanation:
1. The root of a polynomial is when the y-value equals 0. So set the equation euqal to 0:
2. Solve with the quadratic formula and you get:
and 
which is x = .23 and x = 1.43.
