Answer:
x = 1/2 and x = 9/2
Step-by-step explanation:
To solve this equation: |2x-5|=4 we need two evaluate two cases:
|2x-5| = 2x-5 when x>5/2 ✅
|2x-5| = -2x+5 when x<5/2✅
Then, if x>5/2:
2x-5 = 4 ➡ x = 9/2
Then, if x>5/2:
-2x+5 = 4 ➡ x = 1/2
Then, the two solutions are: x = 1/2 and x = 9/2
Answer:
So then the correct answer is B. $200.
Step-by-step explanation:
Notation
Let X be the average contribution size before John makes his contribution.
Let Y be the total contribution size before John makes his contribution.
Let Z be John's contribution.
We know that for this case $ 75 represent the original average amount before the contribution with 50% increase so we can set up the following equation in order to find the original average amount
And solvong for X we got:
Now we can find the total contribution before the donation with the following proportion:
And then with the formula of average taking in count the 6 values we can find the size of donation Z like this:
So then the correct answer is B. $200.

Step-by-step explanation:
From the question we are told that
The probability of that a person is being called for jury duty in any given year is
Let P(E) be the probability a person being selected in the first year, Let P(Z) be the probability a person being selected in the second year
and Let P(Y) be the probability a person being selected in the third year
Generally the probability that a particular eligible person in this city is selected in both of the next 2 years is mathematically represented as
=>
=>
Generally the probability that a particular eligible person in this city is selected in both of the next 3 years is mathematically represented as
=>
=>
This multiplication of each probabilities is valid because each probability is independent of one another
Answer:
Step-by-step explanation:
the last coordinate would be8,0 because i did it on graph paper and checked it a bunch of time even with my math teacher
