------------------------------------
2) calcule média moda e montante dos grupos de números

a 23,43,65,23,34,23,36,44

b 12,13,10,10,12,16,18,23,15​

Answer 1

A= {0,1,2,4,5,6,7} , B= {1,2,3,4,5}e C={3,4}

a)

$\boxed{\boxed{\mathsf{A\cup\,B=\{0,1,2,3,4,5,6,7\}}}}$

b)

$\boxed{\boxed{\mathsf{B\cup\,C=\{1,2,3,4,5\}=B}}}$

c)

$\boxed{\boxed{\mathsf{A\cup\,C=\{0,1,2,3,4,5,6,7\}}}}}$

d)

$\boxed{\boxed{\mathsf{A\cap\,B=\{1,2,4,5\}}}}$

e)

$\boxed{\boxed{\mathsf{A\cap\,C=\{4\}}}}$

f)

$\boxed{\boxed{\mathsf{B\cap\,C=\{3,4\}}}}$

g)

$\boxed{\boxed{\mathsf{A\cap\,B\cap\,C=\{4\}}}}$

2)

a)

média:

$\overline{m}=\dfrac{23+43+65+23+34+23+36+44}{8}\approx36,37$

mediana:

$\overline{m_{e}}=\dfrac{23+34}{2}=28,5$

Moda:

$\boxed{\boxed{\mathsf{mo=23}}}$

b)

média

$\overline{m}=\dfrac{12+13+10+10+12+16+18+23+15}{9}\approx14,33$

mediana:

$\boxed{\boxed{\mathsf{\overline{m_{e}}=12}}}$

Moda:

$\boxed{\boxed{\mathsf{mo=10}}}$
