Is 3/8 estimated to be closer to 0 or 1?

kolezko [41]

The cut-off point is 0.5: higher than this would be closer to 1, and lower would be closer to 0

and 3/8 is lower than 0.5: we know this because a bigger number, 4/8 is equal to 0.5

so it's closer to 0!

Suppose you have rolled a six-sided die fifty times and recorded the result of each roll.

a_sh-v [17]

Using it's concept, it is found that the relative frequency probability of rolling an even number based on this experiment is $\frac{11}{25}$ .

A relative frequency is the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

50 dices are thrown, hence $T = 50$ .
22 resulted in an even number, hence $D = 22$

The <u>relative frequency</u> is given by:

$f = \frac{D}{T} = \frac{22}{50} = \frac{11}{25}$

Answer:

$Cost = 112.266$ cent/km

Step-by-step explanation:

Given

$Unit\ cost = R17.82/litre$

$Rate = 6.3litre/100km$

Required

The fuel cost in $cent\ per\ km$

This is calculated using:

$Cost = Unit\ cost * Rate$

$Cost = R17.82/litre * 6.3litre/100km$

$Cost = R17.82 * 6.3/100km$

$Cost = R1.12266/km$

Multiply by $100$ to get the cost in cents

$Cost = 1.12266 * 100$ cent/km

$Cost = 112.266$ cent/km
