This is a ratio problem 24/144 as 54/y - cross multiply and get y=324

Given the scatter plot, choose the function that best fits the data.

geniusboy [140]

Considering the scatter plot, the function that best fits the data is given by:

f(x) = 3x².

<h3>What is the function that best fits the data?</h3>

To find the function that best fits the data, we have to look at the scatter plot, which gives a series of points (x,y).

We have that:

When x increases, y also increases, hence the function is increasing, which removes the option f(x) = -3x.

The increase looks "faster" than a linear increase, hence a quadratic model should be used, thus removing option f(x) = 3x.

Hence the function that best fits the data is given by:

f(x) = 3x².

-18, 10, -20, -11, 9, 18 Mean Median Mode Range

Vlada [557]

Mean = -2

Median = -1

Mode = Nil

Range = 38

Step-by-step explanation:

Given data is:

-18, 10, -20, -11, 9, 18

Arranging the data in ascending order

-20, -18, -11, 9, 10, 18

Mean:

Mean is given by the formula

$Mean=\frac{Sum}{items}$

Items are: 6

$Mean = \frac{-20-18-11+9+10+18}{6}\\= \frac{-12}{2}\\= -2$

Mode:

Mode is the most frequent value in the data. So,

As there is no value repeated in the data. There is no mode

Median:

Median is the middle value of the data. As the no. of data value are even,

the average of middle 2 values is mode.

Note that the data has to be arranged in ordered to find median

Here,

$Median = \frac{-11+9}{2}\\=\frac{-2}{2}\\= -1$

Range:

Range is the difference between the largest and smallest value of the data

Here

Largest value = 18

Smallest value = -20

So,

$Range = Largest\ value-Smallest value\\= 18-(-20)\\= 18+20\\=38$

Hence,

Mean = -2

Median = -1

Mode = Nil

Range = 38

Eight more than four times a number is negative twelve

quester [9]

The equation is 4x+8=-12 so you subtract 8 from both sides to give you 4x=-20, then you divide by 4 to get x=-5
