Answer:
-44
Step-by-step explanation:
It is easier to compare a positive number and a negative number because it’s just like regular adding
1 3/4 of the cup will be the other liquid because if you take 1/4 from 2, that would be 1 3/4.
<span>The mean of a set of data is 148.87 and its standard deviation is 68.29. Find the z score for a value of 490.19
the z-score is given by:
z=(x-</span>μ<span>)/</span>σ
plugging in the values in the expression we get:
z=(490.19-149.87)/68.29
z=340.32/68.29
z=4.9835
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for 
, as following:
Therefore, as you can see, the answer is:
