The probability that an archer hits the target when it is windy is 0.4; when it is not windy, her probability of hitting the tar
stiks02 [169]

Answer:

x = 6

Step-by-step explanation:

The probability that this archer hits her first shot is given by t the probability of being windy and that she hits the shot added to the probability of not being windy and that she hits the shot:

P(H_{first}) = P(H_w)*P(W)+P(H_{nw})*(1-P(W))\\P(H_{first})=0.4*0.3+0.7*(1-0.3)\\P(H_{first})=0.12+0.49 = 0.61

If the probability that she hits the target on her first shot is 0.x1, the value of x is:

P(H_{first})=0.61=0.x1\\x=6

Write the equation of a line that is parallel to 4x-2y=3 and is passing through the point (2,1)
Temka [501]

Answer:

y= 2x -3

Step-by-step explanation:

Let's rewrite the given equation into the form of y=mx+c, so that we can find the gradient of the line. In this form, m (coefficient of x) is the gradient.

4x -2y= 3

2y= 4x -3

<em>Divide</em><em> </em><em>by</em><em> </em><em>2</em><em> </em><em>throughout</em><em>:</em>

y = 2x - 1 \frac{1}{2}

Thus the gradient is 2.

Parallel lines have the same gradient thus the line would also have a gradient of 2.

Substitute m=2 into the equation:

y= 2x +c

To find the value of c, substitute a pair of coordinates.

When x=2, y=1,

1= 2(2) +c

1= 4 +c

c= 1 -4

c= -3

Thus, the equation of the line is y= 2x -3.
