Answer:

0.4

Step-by-step explanation:

P(A)=0.6

P(B)=0.3

P(B∩A)=0.5

P(A∪B)=P(A)+P(B)-P(A∩B)

P(A or B)=P(A∪B)=0.6+0.3-0.5=0.9-0.5=0.4

Give the equation of the circle centered at the origin and passing through the point (0,-8)

Norma-Jean [14]

Answer:

The answer to your question is x ² + y² = 64

Step-by-step explanation:

Process

1.- Find the length of the radius

C (0, 0)

P (0, -8)

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

d = $\sqrt{(0- 0)^{2}+ (-8 - 0)^{2} }$

d = $\sqrt{64}$

d = 8

2.- Find the equation of the circle

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

h = 0 and k = 0

$(x - 0)^{2} + (y - 0)^{2} = 8^{2}$

x² + y² = 64

Math question down below

y=1 is the answer, there is no slope, so the formula y=mx+b turns into y=b, since 1 is the intercept 1 is b.

Q. A room measure 3m 55cm by 2m 25 cm. What is the perimeter of the room?

Bond [772]

Answer:

100cm = 1m

Thus, one more step should be added to your working to arrive at the final answer:

Perimeter

= 10m 160cm

= 11m 60cm

This is because 160cm= 100cm +60cm, which is also equivalent to 1m 60cm.

Alternative working:

Convert all the units to cm first.

$\boxed{1 \: m= 100 \: cm}$

Length

= 5m 55cm

= 300cm +55cm

= 355cm

Breadth

= 2m 25cm

= 200cm +25cm

= 225cm

Perimeter

= 2(length +breadth)

= 2(355 cm +225 cm)

= 2(580 cm)

= 1160 cm

= 11m 60cm

From the second last step to the last step, you could divide 1160 by 100 to find how many meters are there. You would get a quotient of 11 and a remainder of 60. Since this 60 cannot be changed into meters as a whole number, we can leave it as 11m 60cm. Otherwise, it is also correct to leave it as 1160cm or 11.6m unless otherwise stated.

However, 10m 160cm is not preferred since the conversion of cm to m is done partially, as the 160 cm can still be further simplified.
