Answer:
The answer would be the second plot
Step-by-step explanation:
The frequency table show how many sick patients there are in a single age range. In the first two plots, the total dots between numbers 24, 25, 26, 27, 28, and 29 add up to 3, and the other 2 plots do not, so those are not correct.
When we add up the total of dots from ages 30-34 on the first plot, there are only 4 sick patients. On the second graph, there are 6 total patients in that age range. Therefore, the dot plot that corresponds with the frequency table is the second one.
Answer:
45
Step-by-step explanation:
a = 78/20=45
Answer: D.The domain and range of the function are the same.
Step-by-step explanation: Given function f(x)=-√-x.
The given function is a square root function and we have minus sign in front of x inside square root.
A square root always defined for positive values or 0.
In order to get a positive number or 0 inside square root, let us solve the inequality:
![-x\geq 0](https://tex.z-dn.net/?f=-x%5Cgeq%200)
On dividing both sides by -1, the inequality sign would get flip and we get
<h3>Domain:
![x \leq 0.](https://tex.z-dn.net/?f=x%20%5Cleq%200.)
</h3>
We can see that we have a negative sign in front of square root. So, the value of f(x) would be always a negative number or 0.
<h3>Therefore, range would also be :
![x \leq 0.](https://tex.z-dn.net/?f=x%20%5Cleq%200.)
.</h3><h3>Therefore, correct option is D option.</h3>
If you simplify it, it would be that same as 2/3.
C is the solution to the problem
