1350 cm^2. First, we must find the area of one side. The formula for the area of a square is S^2 or S*S, so plugging in the value of the side we get 15*15=225. So each side of the cube is 225 cm^2, so since there are 6 sides, we just multiply by 6 (225*6=1350).

Which shows the equation y – 4 = 2(x + 3) written in standard form? A. –2x + y = 10 B. –2x + y = 7 C. y = 2x + 7 D. y = 2x + 10

stiks02 [169]

Answer:

A. $-2x+y=10$

Step-by-step explanation:

Given:

The equation of a line is given as:

$y-4=2(x+3)$

The standard form of an equation of a line is of the form:

$Ax+By=C$ , where, A, B and C are constants.

Now, we have to rearrange the above equation in standard form.

$y-4=2(x+3)$

Distribute 2 to $x+3$ . This gives,

$y-4=2x+6$

Add 4 on both sides. This gives,

$y-4+4=2x+6+4\\y=2x+10$

Now, add -2x on both sides. This gives,

$y-2x=2x-2x+10\\y-2x=10$

Now, rearrange in standard form. This gives,

$-2x+y=10$

Therefore, the standard form is given as $-2x+y=10$

Suppose A and B are mutually exclusive events, and that P(B)=0.03 and P(A OR B)=0.52. Find P(A)

Angelina_Jolie [31]

Answer:

P(A) = 0.49

Step-by-step explanation:

Given:

A and B are mutually exclusive events.

P(B) = 0.03

P(A or B) = 0.52

If two events A and B are mutually exclusive events, then there are no elements common in both the events. So, the probability of their intersection is 0.

Now, as per probability addition theorem:

P(A or B) = P(A) + P(B) + P(A and B)

For mutually exclusive events, P(A and B) = 0. So,

P(A or B) = P(A) + P(B) + 0

P(A or B) = P(A) + P(B)

Plug in the given values and solve for P(A). This gives,

0.52 = P(A) + 0.03

P(A) = 0.52 - 0.03

P(A) = 0.49

Therefore, the probability of occurrence of event A is P(A) = 0.49.
