Do the following summarize a categorical variable or a numerical variable? If the data is numerical, also state if it is continu

Leviafan [203]

The batting average of a baseball player is classified as a numeric continuous variable.

<h3>What are categorical and numerical variables?</h3>

Categorical variables assume labels, for example, good or bad.

Numerical variables assume numbers, as it own name says.

A batting average is given by the <u>number of hits divided by the number of at bats</u>, hence it is a numeric value.

<h3>What are continuous and discrete variables?</h3>

Continuous variables assume real values.

Discrete variables assume integer values.

The batting average is a real number, hence it is also a continuous variable.

£980 is divided between Caroline, Sarah & Gavyn so that Caroline gets twice as much as Sarah, and Sarah gets three times as

Nitella [24]

Sarah has received £ 294

<u><em>Solution:</em></u>

Given that £980 is divided between Caroline, Sarah & Gavyn

Let "c" be the amount received by caroline

Let "s" be the amount received by sarah

Let "g" be the amount received by gavyn

<em><u>Caroline gets twice as much as Sarah</u></em>

amount received by caroline = twice as much as Sarah

amount received by caroline = 2(amount received by sarah)

c = 2s ---- eqn 1

<em><u>Sarah gets three times as much as Gavyn</u></em>

amount received by sarah = three times as much as Gavyn

amount received by sarah = 3(amount received by gavyn)

s = 3g ------- eqn 2

Given that total amount is 980

c + s + g = 980 --- eqn 3

<em><u>Let us solve eqn 1, 2, 3 to get values of "c" "s" "g"</u></em>

From eqn 2,

$g = \frac{s}{3}$ --- eqn 4

Substitute eqn 1 and eqn 4 in eqn 3

$2s + s + \frac{s}{3} = 980\\\\\frac{6s + 3s + s}{3} = 980\\\\6s + 3s + s = 980 \times 3\\\\10s = 2940\\\\s = 294$

Thus sarah has received £ 294

If you were asked to load 225 bixes on a truck , and boxes are crated. With each nine boxes how many crates would you need to lo

Lubov Fominskaja [6]

225 divided by 9 to figure out the number of crates needed.
225/9=25

So 25 crates are needed to load all boxes on the truck.
