Answer:
0-2 x-intercepts and 0-1 y-intercepts
Step-by-step explanation:
A quadratic function can have anywhere from 0 to 2 x-intercepts. This is possible because a function can have 0, 1, or 2 solutions.
A parabola can also have either 0 or 1 y intercepts. It is possible for the function to not intercept the y axis at all, and it is also possible for it to intercept it exactly one time.
Answer:
Step-by-step explanation:
100%/x%=40/26
<span>(100/x)*x=(40/26)*x - W</span>e multiply both sides of the equation by x
<span>100=1.53846153846*x - W</span>e divide both sides of the equation by (1.53846153846) to get x
<span>100/1.53846153846=x </span>
<span>65=x </span>
x=65
<span>Now we have: </span>
<span>26 is 65% of 40

Answer:
<h2>Option 2 is the right answer.</h2>
Step-by-step explanation:
We need to check if the two characteristics, <u>having blue eyes and being deaf are independent of each other or not</u>.
The above two characteristics will be independent if ![[Probability of being deaf with blue eyes] = {Probability of being deaf } {Probability of having blue eyes}](https://tex.z-dn.net/?f=%5BProbability%20of%20being%20deaf%20with%20blue%20eyes%5D%20%3D%20%7BProbability%20of%20being%20deaf%20%7D%20%7BProbability%20of%20having%20blue%20eyes%7D)
Now, the probability of having blue eyes is 
.
The probability that the Dalmatians will be deaf is 
.
The probability of being deaf with blue eyes is 
.
Since, 38 is not equals to 42, the two characteristics are not independent.
