Given that v^y = 1/ 5 root v, Work out the value of y.

1 answer:

4 0

So if v^y = 1/(5 root V), then v^y = 1/(V^(1/5)) just like how X^(1/2) = 2 root X or more commonly known as the square root.
So if v^y = 1/(V^(1/5)), then v^y = V^(-1/5) because X^(-1) = 1/X
Thus you get y = -1/5 because V^y = V^(-1/5)
Hope this helps!

Which statement is true for the vertical number line? A. -2.5 is located below -3.5 . B. -4.8 is located below 4.8 . C. 3.25 is

meriva

Answer:

B. -4.8 is located below 4.8 . TRUE

Step-by-step explanation:

The vertical line is called the Y - AXIS.

Here also, the integers are expressed as same as the horizontal axis.

.... -5, -4, -3, -2, -1 , 0 , 1 2,3 4,5 ....

In vertical line, If we move above 0, the value INCREASES.

If we move Below 0, the value DECREASES.

Now, consider the given cases:

A. -2.5 is located below -3.5 .

Here, as -3 lies Below -2.

So, -2 > -3 ⇒ -2.5 > -3.5

So, -2.5 is located ABOVE 3.5.

B. -4.8 is located below 4.8 .

Here, as -4 lies Below 4.

So, 4 > -4 ⇒ 4.8 > -4.8

So, -4.8 is located BELOW 4.8.

C. 3.25 is located above 3.75 .

Here, 3.75 > 3.25

⇒ 3.75 is located ABOVE 3.25.

D. -0.5 is located below -1.5 .

Here, as -1.5 lies Below 0.5.

So, -0.5 > -1.5

⇒ -0.5 is located ABOVE -1.5.

E. 0 is located below -0.87 .

Here, as -0.87 lies Below 0.

So,0 > -0.87

⇒ 0 is located ABOVE-0.87.

2 cards are drawn from a standard deck without replacement. What is the probability that at least one of the cards drawn is an a

olya-2409 [2.1K]

Answer:

<h2>The answer is 0.1493.</h2>

Step-by-step explanation:

In a standard deck there are 52 cards in total and there are 4 aces.

Two cards can be drawn from the 52 cards in $^{52}C_2 = \frac{52!}{50!\times2!} = 51\times26$ ways.

There are (52 - 4) = 48 cards rather than the aces.

From these 48 cards 2 cards can be drawn in $^{48}C_2 = \frac{48!}{46!\times2!} = 47\times24$ ways.

The probability of choosing 2 cards without aces is $\frac{47\times24}{51\times26} = \frac{188}{221}$ .

The probability of getting at least one of the cards will be an ace is $1 - \frac{188}{221} = \frac{33}{221} = 0.1493$ .
