Answer:

option B

Elia multiply the dividend by 100 instead of 10.

Step-by-step explanation:

Given that,

divisor  = 0.6

dividend = 1.848

Elia decided to multiply each by 10 to get

<h3>divisor  = 0.6 x 10 = 6</h3><h3 /><h3>dividend = 1.848 x 10 = 18.48</h3>

but unfortunately she multiply the dividend by 100

As,

1.848 x 100 = 184.8

So,

Elia's error was that she multiply the dividend by 100 instead of 10.

A coin is tossed 600times with the frequencies as:
brilliants [131]

Answer:

  • see below

Step-by-step explanation:

Total number of trials =600.

Number of heads = 342.

Number of tails = 258

On tossing a coin,

let  \: E_1  \: and  \: E_2  \: be  \: the  \: events \:  of \:  getting  \: a  \: head

and of getting a tail respectively.

then,

1)  \: P \:  (getting \:  a  \: head) = \: P \:  (E_1)

\longrightarrow \:  \frac{number \: of \: heads \: coming \: up}{total \: number \: of \: trials}

\longrightarrow \:  \frac{342}{600}  =  \frac{57}{100}

\longrightarrow \: 0.57

\red{ \rule{150pt}{3pt}} \:

2) P (getting \: a\: tail) =P (E_2)

\longrightarrow \:  \frac{number \: of \: tails \: coming \: up}{total \: number \: of \: trials}

\longrightarrow \:  \frac{258}{600}  =  \frac{43}{100}

\longrightarrow \: 0.43
