Mary bowled six games this week. Her scores were 138,151,198,147,156, and 173. What was her average for those

erica [24]

The average of scores is 160.5

Step-by-step explanation:

Mean is the sum of all values divided by the number of values.

Given scores are:

138,151,198,147,156, and 173

The formula for average score is given by:

$Avg = \frac{Sum}{items}$

Putting values

$Avg = \frac{138+151+198+147+156+173}{6}\\Avg = \frac{963}{6}\\= 160.5$

The average of scores is 160.5

In scientific notation

mrs_skeptik [129]

$(3.9 \times {10}^{ - 3}) + 0.0026 =$

$(39 \times {10}^{ - 4}) + (26 \times {10}^{ - 4}) =$

$39 \times {10}^{ - 4} + 26 \times {10}^{ - 4} =$

$Factoring \: {10}^{ - 4}$

${10}^{ - 4} \times (39 + 26) =$

$65 \times {10}^{ - 4} = 6.5 \times {10}^{ - 3}$
