Answer:
C. 0.492
Step-by-step explanation:
All I did was add the two numbers. Add them like normal, even though they are in decimal form. You could also use a calculator. If you don't have one, there should be one programed into your phone and computer.
0.467
+ 0.025
= 0.492
I hope this helps! Please let me know if you have any more questions or need any more help. Have a great day!
Hello!
Answer: 80 kilograms
Explanation: The sumo wrestler wanted to gain weight so an amount is being added to his current weight. As the question tells us, t is the months. Therefore 5.4 is the amount gained per month, resulting in 80 being the wrestler's starting weight. Whenever you are working on a problem like this just go through and figure out based on what you are told, what certain parts are, then go from there.
I hope that helps you!
Good luck!
Answer:
(a) The mean of the weight of the mice is 50.26 grams.
(b) The standard deviation of the weight of the mice is 14.08 grams.
Step-by-step explanation:
(a)
The mean is given as follows:
Thus, the mean of the weight of the mice is 50.26 grams.
(b)
Compute the standard deviation as follows:
![s=\frac{1}{\sum f_{i}-1}[\sum f_{i}x_{i}^{2}-\frac{1}{\sum f_{i}}(\sum f_{i}x_{i})^{2}]](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B1%7D%7B%5Csum%20f_%7Bi%7D-1%7D%5B%5Csum%20f_%7Bi%7Dx_%7Bi%7D%5E%7B2%7D-%5Cfrac%7B1%7D%7B%5Csum%20f_%7Bi%7D%7D%28%5Csum%20f_%7Bi%7Dx_%7Bi%7D%29%5E%7B2%7D%5D)
![=\frac{1}{100-1}[254001-\frac{1}{100}(5026)^{2}]\\\\=\frac{1}{99}\times 1394.24\\\\=14.08323\\\\\approx 14.08](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B100-1%7D%5B254001-%5Cfrac%7B1%7D%7B100%7D%285026%29%5E%7B2%7D%5D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B99%7D%5Ctimes%201394.24%5C%5C%5C%5C%3D14.08323%5C%5C%5C%5C%5Capprox%2014.08)
Thus, the standard deviation of the weight of the mice is 14.08 grams.
Answer:
Rose bought 14 packages of granola bars.
Step-by-step explanation:
Total bill = 1 bag of potatoes + x amount of packages of granola bars
Total bill = $74.25
1 bag of potatoes = $6.00
1 package of granola bar = 5.25
We set the equation to:
74.25 = 6.00 + 5.25x
Subtract 6.00 from both sides:
68.25 = 5.25x
Divide both sides by 5.25 to leave x by itself
68.25/5.25 = 5.25x/5.25
13 = x
This means Rose bought 13 packages of granola bars.
Let's recheck our work by inputting x = 13 into the equation:
74.25 = 6.00 + 5.25(13)
74.25 = 6.00 + 68.25
74.25 = 74.25
Answer:
Step-by-step explanation:
l = 7 in
w = 11 in
h = 5 in
Surface area = 2*(lw +wh +hl)
= 2*(7*11 + 11*5 + 5*7)
= 2* (77+ 55 + 35)
= 2 * 167
= 334 square inches
