Answer:

y = -3x - 3.

Step-by-step explanation:

The slope of the line = (y2-y1)/(x2-x1) where (x1, y1) and (x2, y2) are 2 points on the line.

Here x1 = -1 , x2 = 0, y1 = 0 and y2 = -3.

So the slope = (-3 - 0) / (0 - (-1))

= -3/1

= -3.

The equation of a line can be written as

y = mx + c where m = the slope and c = the y-intercept.

So substituting m = -3 and the point (-1, 0):

0 = -3(-1) + c

c + 3 = 0

c = -3.

So our equation is y = -3x - 3.

Pls help!!!!The probability of hitting a target on a single trial is 40%,Find the probability of hitting the same target 5/8 tim

azamat

Probability hit=40%=4/10
probability no hit=1-p (hit)=1-4/10=6/10
probability= p(hit)+p(hit)+p(hit)+p(hit)+p(hit)+p (no hit)+p (no hit)+p (no hit)
probability=4/10×4/10×4/10×4/10×4/10×6/10×6/10×6/10
=0.0022

Citrus2011 [14]

Answer: 2500

Step-by-step explanation:

Given

2% of the fans are teenagers

If there are 50 teenagers at the football stadium

Suppose there are x no of people in the stadium

So, we can write 2% of x is 50

$\Rightarrow 2\%\times x=50\\\Rightarrow 0.02x=50\\\Rightarrow x=\dfrac{50}{0.02}=2500$
