8x-5y=-118x−5y=−118, x, minus, 5, y, equals, minus, 11 xxx-intercept: \Big((left parenthesis ,,comma \Big))right parenthesis yyy

ZanzabumX [31]

Given:

The equation is

$8x-5y=-11$

To find:

The x-intercept and y-intercept of the given equation.

Solution:

We have,

$8x-5y=-11$

For x-intercept, y=0.

$8x-5(0)=-11$

$8x=-11$

$x=-\dfrac{11}{8}$

$x=-1.375$

So, the x-intercept is at point (-1.375,0).

For y-intercept, x=0.

$8(0)-5y=-11$

$-5y=-11$

$y=\dfrac{-11}{-5}$

$y=2.2$

So, the y-intercept is at point (0,2.2).

You shuffle a deck of 26 cards represent the letters of the alphabet you randomly select a card from the deck what is the theore

elixir [45]

Answer:

$\dfrac{4}{13}$

Step-by-step explanation:

There are 26 Letters in the alphabet.

n(S)=26

In the word TOUCHDOWN, we have the letters T,O,U,C,H,D,W,N

There are 8 letters in the word Touchdown.

n(Touchdown)=n(T)=8

Therefore, the theoretical probability that the card represents one of the letters in the word touchdown

$=\dfrac{n(T)}{n(S)} \\=\dfrac{8}{26}\\=\dfrac{4}{13}$

Answer:

<h2>The probability of being all females is 60%.</h2><h2>The probability of being all males is 40%.</h2>

Step-by-step explanation:

We know that 40% of the population is male.

If someone selected 9 students, the probability of being all males is 40%. But, the probability of being all females is 60%, because there are only two genders and females represents the complete set of the given probability.
