Arithmetic: uses properties of addition
Geometric: uses properties of multiplication

1 + 2 = 3 + 2 = 5
This sequence is Arithmetic

Arithmetic uses common different: how much the number goes up by each time; rate of change

ZanzabumX [31]
Let the integers be x and x+1.

x = 6 + 2(x + 1)

x = 6 + 2x + 2

Determine measurements of data for the following numbers:
Leno4ka [110]

Answer: mean=87, median=87.5 and range=18

Step-by-step explanation:

Mean:

First add all the numbers

78+95+77+92+87+79+94+86+88+94 = 870

Then you divide the answer by counting the numbers

870÷10

=87

Median:

First arrange the numbers in ascending order (from smallest to largest)

77, 78, 79, 86, 87, 88, 92, 94, 94, 95

pick the two middle numbers which is 87 and 88

then you do \frac{87+88}{2}

                = 175÷2

                =  87.5

range = Largest number - smallest number

= 95-77

= 18

Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?
topjm [15]

\huge \mathcal{ Answer࿐}

  • Error (e) = 50 - 42 = 8 feet

  • assumed value (a) = 42 feet

\boxed{ \mathrm{ \% \: error =  \dfrac{error}{assumed \: value}  \times 100}}

  • \mathrm{ \% \: error  =\dfrac{8}{42}}  \times 100

  • \mathrm{ \% \: error  = \dfrac{800}{42} }

  • \mathrm{ \% \: error  = 19.04 \%}
