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
Volume=4156.33
use the volume formula and 1/2 the diameter to get “r” and plug it in and you should get 4156.33.
3t - 15 = 2t + 10
t = 25
<Y = 2(25) + 10 = 60
<X = 4r
so
4r + 60 = 180
4r = 120 (<X = 4r)
answer
<X = 120
