Answer:
Step-by-step explanation:
Let's start defining the conditional probability of an event :
Given two events A and B :
with P(B) > 0
Where P(A/B) is the probability of event A given that event B occur
P(A,B) is the probability of the event in which A and B occur both at the same time.
Let's write the events for our exercise
S : ''A random student speaks Spanish''
I : ''A random student speaks Italian''
Applying the conditional equation we obtain :
Then, 0.375 is the probability that we are looking for
Joan: 12 years old
Amber: 22 years old
If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)
Answer:
2 x 0 = 0
Any number multiplied by 0 equals 0.
Step-by-step explanation:
If multiplication tells you how many times to add a certain number, then multiplying by 0 means that you have nothing to add because 0 means nothing. So, 3 x 0 means that you are adding 3 zero, or no, times. ... You get 0 because you're still not adding anything. Nothing added to nothing is still nothing.

Answer:
If KF = 19, then <u><em>KM = 38</em></u>.
Step-by-step explanation:
The point that intersects the two diagonals of a symmetrical quadrilateral marks the halfway point of the diagonals. Since we know that KF = 19 and that 2(KF) = KM, as KM is a diagonal of this parallelogram, we just do the following:
2(KF) = KM
2(19) = KM
<u>38 = KM</u>
