D. x + (-x) = 0

That is the answer because if you are x feet above sea level, to get back to sea level, which equals zero (0), you need to go down the same amount you went up (x), so you need to go down x feet (-x).

On a diagram of the arena, the car park's length is 15 cm. The scale is 1:100.
faltersainse [42]

If a diagram has a scale of 1:100, that means that the real thing is 100 times larger. To find how long the real thing is, that means that we need to multiply the length on the diagram by 100. 100 * 15 is 1500. But, that is 1,500 cm. To convert it into meters, we need to divide by 100. That's because there's 100 centimeters in every meter. 1500/100 is 15, which means that the actual length of the car park is 15 meters.

P(A)=0.40 p(b)= 0.50 p(A and b) = 0.10 what is p(b/A)? <br><br><br>plz help​
yawa3891 [41]

Answer:

The answer is C, 0.25.

Step-by-step explanation:

In order to find the probability of (B | A), you need to use this formula:

Conditional Probability (A has already occured)

P(B | A) = P(A and B)

                     -------

                      P(A)

If you subsitute in the values you get this:

P(B | A) = 0.10

               ------

               0.40

0.1 divided by 0.4 is equal to 0.25.
