<span>
Data:
h (height) = 12 in
r (radius) = 9 in
Use: </span>
Solving:
To solve this, we need to use the z test. The formula for
z score is:
z = (x – u) / s
where x is sample value = 141.4 mm and above, u is mean
value = 140 mm, s is standard dev = 8 mm.
z = (141.4 – 140) / 8
z = 0.175
From the standard probability tables, the p value at z =
0.175 using right tailed test is:
P = 0.4306
Answer:
The correct answer is <u>742,000</u>
Step-by-step explanation:
Answer:
2/6 and 4/12
Step-by-step explanation:
When you reduce both of these fractions, they come out to 1/3.
Dividing both terms of 2/6 by 2, the greatest common factor (GCF), would equal 1/3.
And dividing both terms of 4/12 by 4, which is the GCF in this case, would equal 1/3.
