(-5,2) concave up
Hope this helps :)
BD is right but PA is wrong, would be BD and MK.
They are all vertical angles.
Answer:
equation of the line is y=x+1
Step-by-step explanation:
the equation of a line has the form y = mx + b
while m is for the slope and b is for the y-intercept.
you can see from the graph that the line intercepts the y-axis at y=1 this is the b.
you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:
<h2>
</h2>
in our case it will be:
then just substitute the values for m and b.
Answer:
2. 1- Experimental probability of rolling a 4 = 40%
3. 2- Theoretical probability is 3% greater than experimental probability.
Step-by-step explanation:
Experimental probability of rolling a 4 = 100 ×
= 100 × 0.4
= 40%
Experimental probability of getting at least one tail =
= 0.72
Theoretical probability of getting at least one tail =
= 0.75
Theoretical probability is 3% greater than experimental probability.
