Answer:
2. domain: {3,4,5,6,7}; range: {2,3,4,5,6}
4. IS a function
Step-by-step explanation:
2. The <em>domain</em> is the list of first numbers of each pair.
The <em>range</em> is the list of second numbers.
4. If each value on the left only has <em>one arrow</em> coming from it, the relation <u>is</u> a function. That is the case here.
__
Contrast that to the problem above (3.). In that one, the number 4 1/2 has two arrows coming from it. That relation is NOT a function.
T ∝ 1/v
<span>so, t = k/v or tv = k </span>
<span>Then, with t = 2.5 and v = 5 we have: </span>
<span>2.5 = k/5 </span>
<span>so, k = 12.5 </span>
<span>Therefore, t = 12.5/v or vt = 12.5 HOPE IT HELPED</span>
Hey You!
Tom:
22*7% = 1.54
His Cousin:
18*7% = 1.26
22 + 1.54 = 23.54
18 + 1.26 = 19.26
So, Tom pays $23.54 and His Cousin pays $19.26 and Tom payed more tax.
Answer: 0.965
Step-by-step explanation:
Given : Water use in the summer is normally distributed with


Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.
