Answer: 591
Step-by-step explanation:
12 x 13= 156
12 x 5= 60 x 2= 120
12 x 5= 60/2= 30 x2= 60
5 x 12= 60
13 x 15= 195
195 + 60 + 60 + 120 + 156= 591

Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
<u>Probability that the mean life of a random sample of 25 bulbs will be less than725 hours </u>
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )
Answer: option B. 4 feet above water.
Explanation:
This is an example of the use of the integer numbers.
Integer numbers are positive, zero and negative numbers.
In this case, zero is used to represent the surface of the water. So, any positive number will be the position above water and any netative number will be the position below water. That is why, while - 4 represents the position of the dolphin below water, 4 represents the position 4 feet above water.
