Which is the best estimate for the sum of 1/12 + 3/8

2 answers:

8 0

The answer would 1/2
to get a good estimate, you should use benchmarks. benchmarks can be 0,1/2. or 1
round 1/12 to 0 and 3/8 to 1/2.
when you add 0 and 1/2, you get 1/2.
that would mean the best estimate would be around 1/2.
hope this helps! :)

A bag contains green marbles and red marbles, 36 in total. The number of green marbles is 1 more than 4 times the number of red

tatuchka [14]

Answer:

Step-by-step explanation:

Total marble = 36

Let red marbles be X

Then green marble is 4X + 1

And 4X + 1 + X = 36

5X = 36 - 1

5X = 35

X = 35/5 = 7

So, green marbles = 4X + 1

= 4(7) + 1

= 29

The following data points represent the number of children in each household on Maple Street. \qquad 0, 1, 2, 1, 20,1,2,1,20, co

zaharov [31]

Answer:

The mean number of the children is 1.2

Step-by-step explanation:

Given

Children: 0, 1, 2, 1, 2

Required

Determine the Mean number

The mean of a set is calculated as follows;

$Mean = \frac{\sum x}{n}$

Where x is the given set and n is the number of sets

In this case, n = 5 children

Hence;

$Mean = \frac{0 + 1 + 2 + 1 + 2}{5}$

$Mean = \frac{6}{5}$

$Mean = 1.2$

<em>Hence, the mean number of the children is 1.2</em>

The equation 2x² + 2y2 – 8x - 12y + 16 = 0 defines a circle.

mixas84 [53]

Answer:

C, E

Step-by-step explanation:

Here, we want to change the equation of a circle from general form to standard form. This is done by making the leading coefficients 1, completing the squares, and then rewriting the equation in standard form.

The leading coefficients of the given equation are 2, so we first want to divide by 2. This gives ...

x² +y² -4x -6y +8 = 0

Subtracting 8 puts us in better position to complete the squares.

x² +y² -4x -6y = -8

Now, we can add the squares of half the coefficients of the linear terms.

(x² -4x +4) +(y² -6x +9) = -8 +13 . . . . . . matches C

And we can simplify this to the standard form equation:

(x -2)² +(y -3)² = 5 . . . . . matches E
