The student simplified wrong because when he brought a to the numerator, he forgot to change the sign of the exponent. Instead of getting a^2 in the numerator (by adding 4 + -2), he should have gotten a^6 (by adding 4 + 2)

Answer:

y = 3x + 3

Step-by-step explanation:

First, you check for the y-intercept, which is 3 for this equation.

In order to find the slope, pick two points and apply the slope formula.

I would just use rise/run. The slope should be 3/1.

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,

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

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

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

$\longrightarrow \: 0.57$

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

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

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

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

$\longrightarrow \: 0.43$
