Answer:
Step-by-step explanation:
First start by finding the values of the numbers being multiplied together.
5^-2 = 25
This equals a positive 25 because when ever you multiply a negative by a negative it always equals a positive number. -5 x -5 = 25
= 2
This is asking what x what x what equals eight. Remembering that the square root of 4 is 2. We can determine that since 4 x 2 = 8 the cube root of 8 is 2.
2 x 2 x 2 = 8 and 8 divided by 2 divided by 2 = 2
So now solve the equation we have now. 25 x 2 =?
25 x 2 = 50
And 50 is our answer.
Answer:
Step-by-step explanation:
<h2>This is an independent event probability problem , that is the first event does not affect the occurrence of the second event.</h2>The sample space of the first die is S1= {1,2,3,4,5,6}
The sample space of the second die is S2= {1,2,3,4,5,6}
1. the probability that the first number cube shows a Four pr (4)=
2. the probability that the second number cube shows an odd number=
odd numbers in the sample space are 1,3,5= 3
pr(odd)
For the two event to happen the probability is =
Answer:
Step-by-step explanation:
Step 1) Replace y = f(x)
Step 2) Exchange x and y
Step 3) Solve for y
Subtracting both sides by -5
Dividing both sides by 2
Step 4) Replace
