Tammy has scored 82, 78, and 93 on her previous three tests. What score does she need on her next test so that her average (mean

Lyrx [107]

Answer:

She needs a grade of 71 on her next text.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values in the data-set divided by the number of values.

Tammy has scored 82, 78, and 93 on her previous three tests.

Thus, her grades are 82, 78, 93 and x, in which x is her grade in the fourth test.

There are 4 tests.

What score does she need on her next test so that her average (mean) is 81?

We have to find x when the mean is 81. So

$\frac{82 + 78 + 93 + x}{4} = 81$

$253 + x = 324$

$x = 324 - 253$

$x = 71$

She needs a grade of 71 on her next text.
