First, you have to know the formula of finding the area of a triangle. That is bh1/2. You multiple the base and height together and multiply it by 1/2 or divide by 2. You put in the info they gave you in the formula, after that you get 105/8. That is obviously not one of the choices and it is an improper fraction. The way to make it into a whole fraction is to do 105 divided by 8. Then, you get 13, which is the second answer. Finally, the area of the triangle is 13 1/8 squared mm.
In order to determine the probability that the coin chosen is a dime, determine first the total number of sample coins. In this problem, there are 52 coins all in all. Next, divide the number of dimes in the sample with the total number of coins. This gives us 10/52. Simplifying the fraction further yields to 5/26. Thus, the probability that the coin chosen is dime is 5/26. The answer is letter c.
Answer:
22°
Step-by-step explanation:
If the mean is m and the standard deviation is s, then we can say that the temperatures that fall <em><u>within 1 standard deviation of the mean</u></em> will be:
m - s < temperatures < m + s
To we take the sum of mean and standard deviation: 24 + 4 = 28
and, the different of mean and standard deviation: 24 - 4 = 20
So, <em>the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean</em>.
This is the third answer, 22°
This is already in simplest form and cannot be simplified any more. I hope that this helped! Good luck! :)
