Answer:</h2>
Option: D is the correct answer.
The probability is: 0.50
<h2>
Step-by-step explanation:</h2>
Weight/Calories 1000-1500 1500-2000 2000-2500 Total
120 lb. 90 80 10 180
145 lb. 35 143 25 203
165 lb. 15 27 75 117
Total 140 250 110 500
We are asked to find the probability that a person consumes 1500-2000 calories in a day.
Total number of people who were surveyed=500
Total number of people who consume 1500-2000 calories in a day are:250
Hence, Probability is:
250/500=1/2=0.50
If you decrease number by 50% of that number you are basically dividing with 2 hence the answer is 15.
I included the formula and the answer
The correct option is: B. 450
<u><em>Explanation</em></u>
Current value of the investment is
dollars and 30 years ago, the value of the investment was
dollars.
Suppose, the value of investment today is
times greater than the value of the investment thirty years ago.
So, the equation will be........
![n(2.3\times 10^5)=1.035\times 10^8\\ \\ n= \frac{1.035\times 10^8}{2.3\times 10^5}=0.45\times 10^3 = 450](https://tex.z-dn.net/?f=n%282.3%5Ctimes%2010%5E5%29%3D1.035%5Ctimes%2010%5E8%5C%5C%20%5C%5C%20n%3D%20%5Cfrac%7B1.035%5Ctimes%2010%5E8%7D%7B2.3%5Ctimes%2010%5E5%7D%3D0.45%5Ctimes%2010%5E3%20%3D%20450)
Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
Answer:
-7
Step-by-step explanation:
Evaluate the expression for u=10. Subsitute u for 10 and substract it by 17. 10-17= -7
Your answer is -7
