Question

Finding the value for a new score that will yield a given mean

Answer 1

Answer:

Step-by-step explanation:

The mean in this case is calculated by adding all the scores up divided by the number of scores, in that case, we get the equation:

$\frac{74+74+83+x}{4} = 74$ , where x is the score she needs to get

x = 65

Thus the score she needs to get on her next test is 65.
