Answer:

The answer is 87.

Step-by-step explanation:

First, line up the data in order: 81, 83, 91, 94. Next, take off the numbers at the ends until you reach the middle number. Since there is no middle number in this problem, you have to find out the middle of 83 and 91 by lining them up in order: 83, 84, 85, 86, 87, 88, 89, 90, 91. The answer would then be 87.

Answer:

To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

81,83,91,94

since its an even number add up the two middle numbers 83 and 91 to equal 174 then divide by two to have the median of 87

Select the correct location in the expression.

kogti [31]

Answer:

Correct term:60

Step-by-step explanation:

We are given that

$\frac{4x^4-6x^3+6x+3}{x-3}$

The quotient of this expression is given by

$4x^3+6x^2+18x+78+\frac{183}{x-3}$

We have to find the term in this expression which contains an error.

$\frac{4x^4-6x^3+6x+3}{x-3}$

The quotient of this expression is given by

$=4x^3+6x^2+18x+60$

$Dividend=Divisor\times quotient+ remainder$

Using the formula

$4x^4-6x^3+6x+3=(x-3)(4x^3+6x^2+18x+60)+\frac{183}{x-3}$

We can see that in the given expression there is 60 in place of 78.

The error in the expression of quotient is 78.

Correct term is 60.

Zinaida [17]

Answer:

the change in height is 1/100 mile

Step-by-step explanation:

1/50 is also equal to 2/100, and since the previous height was 3/100 then you can just subtract 2/100 from 3/100 to get 1/100

Answer:

Algebra tiles make solving equations, merging like words, or factoring polynomials a visual operation, similar to students using counters to make sense of addition in elementary school, or students using number lines to make sense of integers.
