What is the mean?

Round to the nearest tenth if needed.

Value

the answer is 2.4

Mean=/frac{/sum fx}{/sum f}

Where:

f is the frequency

x is the value

/frac{3+7+5+6+2+x}{6} = 5

23+x=30

x=30-23

x=7

/therefore Mean=/frac{1 / times 7 + 2 / times 1 + 3 / times 3 + 4 / times 2 + 5/times 2}{15}

=/frac{7+2+9+8+10}{15} = / frac{36}{15} = 2.4

Therefore, the mean = 2.4

sorry if its a bit confusing
