Answer:
D.0
Step-by-step explanation:
If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.
Answer: OPTION B.
Step-by-step explanation:
The missing figure is attached.
For this exercise you need to use the Pythagorean Theorem. This is:
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.
Then you can say that:
Therefore, knowing these values, you can substitute them into :
Finally you must solve for PR in order to find its value. This is:
Answer:
17. (2)
Step-by-step explanation:
-5x(x+7)(2x-3)=0
divide both sides by -5
x(x+7)(2x-3)=0
*When the product of factors equals 0, at least one factor is 0*
Set the three factors up to zero
x=0
x+7=0
2x-3=0
solve the equation
x=0
x=-7
x=3/2
this equation has three solutions from least to greatest being; -7,0,3/2
And for number 18, that equation cannot factor, that being the error.
Let me know if this was unclear, I'll be happy to further help!
Answer:
The expected win of a coin flip in dollars is 1.25.
Step-by-step explanation:
To find the expected win of a coin flip, we multiply the probability of each outcome by their earnings, and then add them.
We have that:
3/4 probability of heads. If heads, you win $2.
1/4 probability of tails. If tails, you lose $1.
What is the expected win of a coin flip in dollars?
The expected win of a coin flip in dollars is 1.25.
Answer:
Its b
Step-by-step explanation:
you line them up then multiply the denominator of 3/4 to match 1/8. So if 4x2=8 then you do 3/4x2=6/8. so then the answer would be B and 7/8
Hope that helped and it wasnt confusing haha. (to simplify the answer if B and 7/8)
