Answer:

5/3 = -3/5: 5/3 = -3/5 · 3/5 = -3 · 3/5 · 5 = -9/25 (-0.36)

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction.

The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/3 is 3/5) of the second fraction.

Next, multiply the two numerators.

Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - three fifths divided by five thirds = (negative) nine twenty-fifths.

You are rolling a pair of dice what's is the probability of getting different numbers on both dice

padilas [110]

Answer:

$Pr = 0.833$

Step-by-step explanation:

Given

A roll of a pair of dice

Required

The probability of getting different numbers

First, list out the sample space;

We have:

$S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6),$

$(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)$

$(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)\}$

The total is:

$Total = 36$

The outcomes of the different numbers are:

$Different = \{(1, 2) (1, 3) (1, 4) (1, 5) (1, 6),(2, 1) (2, 3) (2, 4) (2, 5) (2, 6),$

$(3, 1) (3, 2)(3, 4) (3, 5) (3, 6),(4, 1) (4, 2) (4, 3) (4, 5) (4, 6)$

$(5, 1) (5, 2) (5, 3) (5, 4) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) \}$

The total is:

$Different = 30$

So, the probability of having a different outcome is:

$Pr = \frac{Different}{Total}$

$Pr = \frac{30}{36}$

$Pr = 0.833$

Can someone explain

aev [14]

Simple, you are adding a negative to a positive, so think of it as a subtraction, 5/6 - 2/3 = .
2/3 is 4/6.
5/6 - 4/6 = 1/6

Find the inverse of each of the given functions.<br> f(x) = 4x - 12

Lyrx [107]

Answer:

(x + 12) / 4

Explanation:

This was the way I was taught, hopefully it helps you.

y = 4x - 12

x = 4y - 12

x + 12 = 4y

(x + 12) / 4 = y

If x^2=4 then x=2 pleas help me

pochemuha

$x^2=4\Longrightarrow x=4^{2^{-1}}=4^{\frac{1}{2}}=\sqrt{4}=\boxed{2}$

So the first one is correct which implies that the third one is also correct.

But these are not the only ones.

$2x=2\Longrightarrow x=\dfrac{2}{2}=\boxed{1}$

The last one is also correct.

Hope this helps.
