What is the x-intercept of the line described by the equation?
DiKsa [7]

Answer:

(0,-6)

Step-by-step explanation:

recall that the y-intercept is simply the point where the line crosses the y-axis at x = 0.

to find the y intercept, we simply substitute x=0 into the equation and solve for y

12x - 10y = 60, when x = 0,

12(0) - 10y = 60

-10y = 60

y = 60 / (-10)

y = -6

hence the coordinate of the y - intercept is (0,-6)

What is the property of…<br> -2(x-6)=-2x+12
Paraphin [41]

Answer:

0=0

Step-by-step explanation:

-2(x-6)=-2x+12

-2x+12=-2x+12 /+2x

12=12 /-12

each unit square of a 3-by-3 unit-square grid is to be colored either blue or red. for each square, either color is equally like
makkiz [27]

The probability of obtaining a grid that does not have a 2-by-2 red square 16 2/3%

probability : The probability of an event can be calculated by means of probability formula via honestly dividing the favorable quantity of outcomes by way of the total variety of viable consequences.

<u>Step-by using-step clarification:</u>

<u>given that:</u>

form are both square or circle with both equally likely :

for this reason,

P(square) = half of ; P(circle) = half of

color are either blue, pink or inexperienced with the 3 equally likely ;

P(purple) = 1/3 ; P(green) = 1/three ; P(blue) = 1/three

chance of creating a inexperienced circle :

independent probability

P(green n circle) = p(inexperienced) * p(circle)

P(green n circle) = 1/3 * half of

P(green n circle) = 1/6

= 0.16666

(0.16666 * 100%) = 16.6666%

= 16 2/3%

Y is inversely proportional to x.<br> When y = 7, x= 9<br> Work out the value of y when x = 21.
Kazeer [188]

Answer:

y = 3

Step-by-step explanation:

y is inversely proportional to x setup:  y = k/x

'k' is the constant of variation; find this first

7 = k/9

k = 63

now use 'k' to find 'y'

y = 63/21

y = 3

assume that random guesses are made for 8 multiple choice questions on an SAT test, so that there are n=9 trials, each with prob
melamori03 [73]

Answer:

P(x

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

P(x

Then:

P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}

P(x\leq3)=0.0994
