Answer: 6/40 = 3/20
Step-by-step explanation:
The experimental probability is the number of times the desired result was obtained over the number of times the experiment was carried out:
P= Time the event occurs/ Total number of trials
In this case the event we are looking for is rolling a 3 on the number cube. The total number of trials is: 40
because the student rolls the cube 40 times. and the time that he got the number 3 (the times the desired event occurs) is: 6
because he rolls a 3 on the number cube 6 times. Thus our experimental probability to roll a 3 is: P = 6/40
Answer:
the answer is 3(t+2)
Step-by-step explanation:
Hello!
This is real simple!
So let's look at your first ordered pair, (-2,0)
-2 is the x-coordinate, 0 is the y-coordinate. 0 is the origin - or the center - of your graph. Don't put a point yet!
Next, -2 is to the left, so look for -2 on your graph (or count two to the left) Now put a point there. You have plotted (-2,0) on your graph!
Let's try another.
(0,4)
Look at 0 on your graph. The 4 is the y-coordinate, indicating that you'll go up on the y-axis.
Go up 4 on your y-axis
Put a point, you plotted (0,4)
One more?
(2,0)
x. y
Go to positive 2 on your x-axis (since it is the x-coordinate). Notice the y-coordinate is 0, you don't need to go up! Plot your point
You plotted (2,0)
I hope I helped. Please ask if you still need help.
Answer:
Side TV = 16
Step-by-step explanation:
WX is half the value of TV
to solve we have to set up an equation
21-5x=10x-2
because side WX is only have of side TV we have to multiple its side by 2 so now we have
21-5x=20x-4
step 1 add 4 to each side
25-5x=20x
step 2 add 5x to each side
25=25x
step 3 divide each side by 25
x=1
then we plug in x as 1 for side TV and get
21-5 which is equal to 16
Answer:
x = 2/3, -2/3
Step-by-step explanation:
Solve the equation for x by finding a
, b
, and c of the quadratic then apply the quadratic formula.
