The expected value is given by:
E(x)= ∑x*p(x)
thus the expected value of calories will be given by:
E(x)=1/6*60+1/2*42+1/3*90
E(x)=10+21+30
E(x)=61
the answer is 61
Both 52 and 5x-8 are equal to each other due to being parral.
SO 5x-8=52
Add both sides.
8+8 52+8= 60
5x 60
Now divide both sides by 5 and you get 12=x Hope this helps!
Answer:
x = 4
Step-by-step explanation:
x * 5 = 20 * 1
x = 4
To solve this problem you must apply the proccedure shown below:
1. Let's round the value to the nearest hundredth. As you can see, the digit 8 is in the thousandths place and is greater than 5, therefore, you must round up to 0.038.
2. Now express the value as a single digit times a power of 10, as following:
x
Therefore, the answer is:
x
