Answer:
7.85 cm
Step-by-step explanation:
The circumference of a circle can be found using the following formula.
The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.
Now, find the circumference.

Answer:
a) x = 1225.68
b) x = 1081.76
c) 1109.28 < x < 1198.72
Step-by-step explanation:
Given:
- Th random variable X for steer weight follows a normal distribution:
X~ N( 1154 , 86 )
Find:
a) the highest 10% of the weights?
b) the lowest 20% of the weights?
c) the middle 40% of the weights?
Solution:
a)
We will compute the corresponding Z-value for highest cut off 10%:
Z @ 0.10 = 1.28
Z = (x-u) / sd
Where,
u: Mean of the distribution.
s.d: Standard deviation of the distribution.
1.28 = (x - 1154) / 86
x = 1.28*86 + 1154
x = 1225.68
b)
We will compute the corresponding Z-value for lowest cut off 20%:
-Z @ 0.20 = -0.84
Z = (x-u) / sd
-0.84 = (x - 1154) / 86
x = -0.84*86 + 1154
x = 1081.76
c)
We will compute the corresponding Z-value for middle cut off 40%:
Z @ 0.3 = -0.52
Z @ 0.7 = 0.52
[email protected] < x < [email protected]
-.52*86 + 1154 < x < 0.52*86 + 1154
1109.28 < x < 1198.72
Answer:
m<1 = 97
m<2 = 83
m<3 = 112
m<4 = 68
m<5 = 112
m<6 = 68
m<7 = 97
m<8 = 83
m<9 = 97
m<10 = 83
m<11 = 112
m<12 = 68
m<13 = 112
m<14 = 68
m<15 = 97
m<16 = 83
Step-by-step explanation:
Based on the calculations, the unit rate in feet per minute for this walking pace is equal to 250 feet per minute.
<h3>How to calculate the unit rate?</h3>
A unit rate refers to a measurement of a quantity which is calculated as a ratio of one parameter to another.
This ultimately implies that, we would divide the distance covered in feet by the time taken to cover this distance as follows:
Unit rate = distance/time
Unit rate = 3750/15
Unit rate = 250 feet per minute.
