Answer:
$3.15
Step-by-step explanation:
Method 1:
4 oranges = 1.40
9 oranges = x
1.40 / 4 = 0.35
This is 0.35 per orange
0.35 x 9 = 3.15
$3.15
Method 2:
1.40/4 = x/9
12.6 = 4x (cross multiply 9 and 1.4 and cross multiply 4 and x)
x = 12.6 / 4
x = 3.15
$3.15

Answer:
The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem

The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours

Answer: 40 cm^3
Step-by-step explanation:
The volume of a triangular prism is the base * height.
Therefore, the volume is 50 cm^2 * 8 cm = 40 cm^3
