Answer:
y=3x+6
Step-by-step explanation:
Just test this on like a graph or something and you will see it works. Let me know if there is a fault in my answer. Thanks! Have a good day.
First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1
</span>
Answer:
domain:{ [3, ∞], int}
Step-by-step explanation:
this is every possible number that is an integer, so domain:{ [3, ∞], int}
note that the format may be different
Answer:
The relative frequency of landing on tails is 0.3.
Step-by-step explanation:
The relative frequency of an outcome A is:
The number of trials in which the outcome A happened divided by the total number of trials.
In this problem, we have that:
20 coin tosses, so 20 trials. On 6, it landed on tails.
6/20 = 0.3
This means that the relative frequency of landing on tails is 0.3.
