1 answer:

7 0

1/2 or .5
Because there is two tests happening and that is the denominator, and if the probability of only one working it was be 1/2

Solve the equation for the specified variable.<br> T= BA-9, for B<br> What does b=

NARA [144]

9514 1404 393

Answer:

$B=\dfrac{T+9}{A}$

Step-by-step explanation:

Add 9 to both sides of the equation, and divide by the coefficient of B.

T = BA -9

T +9 = BA

(T +9)/A = B

We can rewrite that with B on the left:

B = (T +9)/A

Type the correct answer in each box.

Answer:

$(x-5)^2+(y+4)^2=100$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center and any point that lie on the circle is equal to the radius

we have the points

(5,-4) and (-3,2)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$r=\sqrt{(2+4)^{2}+(-3-5)^{2}}$

$r=\sqrt{(6)^{2}+(-8)^{2}}$

$r=\sqrt{100}\ units$

$r=10\ units$

step 2

Find the equation of the circle

we know that

The equation of a circle in standard form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center

r is the radius

we have

$(h,k)=(5,-4)\\r=10\ units$

substitute

$(x-5)^2+(y+4)^2=10^2$

$(x-5)^2+(y+4)^2=100$

How can you solve standard form and intercept form?

laiz [17]

Answer:

The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.
