According to the 2006 Uniform Crime Report (UCR), the state of Delaware had a population of 853,476 and 5,817 violent crimes. Compute the violent crime rate per 100,000 persons and interpret your result.
Answer:
682
Step-by-step explanation:
Population = 853,476
Number of violent crimes = 5817
We are to get violent crime rate per 100000 persons and interpret the result obtained.
Now if population is 1
Crime = 5817/853476
If population is 100000,
Crime = 5817x100000/853476
= 681.56
= 682
We conclude that the violent crime rate is of 682 crimes per 100000

Step-by-step explanation:
The sales tax in a certain county is 7%. If an item marked at $19.94 is sold within the county, estimate the final cost of the item once tax is included.
Given:
Rate of sales tax = 7%
Marked price of an item = $19.94
To find:
The final cost of the item once tax is included.
Solution:
We have,
Rate of sales tax = 7%
Marked price of an item = $19.94
\(\text{Sales tax}=\dfrac{7}{100}\times 19.94\)
\(\text{Sales tax}=1.3958\)
Now, final cost of the item once tax is included is
\(\text{Final cost}=\text{Marked price}+\text{Sales tax}\)
\(\text{Final cost}=19.94+1.3958\)
\(\text{Final cost}=21.3358\)
Therefore, the final cost of the item once tax is included is $21.3358.
QUESTION 1 MRH CHO3_2001A Discrete PMF Customers select a variety of upgrades when they purchase your software. The number of upgrades purchased per customer is given by the following probability mass function: f(0) -0.50 f(1) - 0.20 f(2)=0.06 f(3) - (unreadable) What is the expected value of the number of upgrades selected? (Hints you will first need to figure out the value of f(3). Remember what do all probability mass functions sum to?) Carry your answer to at least three decimal places.
The expected value of the number of upgrades selected is 1.04.
The given probability mass function provides the probabilities for the number of upgrades purchased per customer. We are asked to find the expected value, which is a measure of central tendency in probability theory. To do this, we need to multiply each possible value of upgrades by its probability and then sum them up.
First, we need to figure out the value of f(3). We know that the sum of all probabilities in a probability mass function is 1. Therefore, we can use the given probabilities to calculate f(3) as follows:
1 = f(0) + f(1) + f(2) + f(3)
1 = 0.50 + 0.20 + 0.06 + f(3)
f(3) = 1 - (0.50 + 0.20 + 0.06)
f(3) = 0.24
Now that we know the value of f(3), we can calculate the expected value as follows:
E(X) = (0 x 0.50) + (1 x 0.20) + (2 x 0.06) + (3 x 0.24)
E(X) = 0 + 0.20 + 0.12 + 0.72
E(X) = 1.04

Megan argues that (5m-3)+(2m+4) models the closure property. What reasoning could Megan use to argue that addition of polynomials is closed?
A.) The coefficients of the sum are whole numbers and the
sum is a polynomial.
B.) The coefficients of the product are integers and the product is a polynomial.
C.) The exponents of the sum are whole numbers and the sum is a polynomial.
D.) The exponents of the sum are integers and the sum is a polynomial.
E.) The terms in the expression are rational numbers in the sum is a polynomial.
Answer:
A. The coefficients of the sum are whole numbers and the sum is a polynomial.
Step-by-step explanation:
The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:
1) \(5\cdot m -3\), \(2\cdot m + 4\) Given
2) \((5\cdot m -3)+(2\cdot m +4)\) Definition of addition
3) \((5\cdot m +2\cdot m ) +[(-3)+4]\) Definition of substraction/Associative and Commutative properties
4) \((5+2)\cdot m +1\) Distributive property/Definition of substraction
5) \(7\cdot m +1\) Definition of addition/Result
Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.

An arrow is shot from 3 ft above the top of a hill with a vertical upward velocity of 108 ft/s. If it strikes the plain below after 9.5 s, how high is the hill?
If the arrow is launched at t0, then write an equation describing velocity as a function of time?
The height of the hill is approximately 25.73 ft. Where v0 is the initial velocity (108 ft/s), g is the acceleration due to gravity \((-32.2 ft/s^2)\),
To find the height of the hill, we can use the formula for the vertical position of an object under constant acceleration:
h = h0 + v0t + 1/2at^2
where h is the final height, h0 is the initial height, v0 is the initial velocity, t is the time, and a is the acceleration due to gravity (-32.2 ft/s^2).
In this case, we are given that the initial height h0 is 3 ft, the initial velocity v0 is 108 ft/s, and the time t is 9.5 s. We want to find the height of the hill, which we can denote as h_hill. The final height is the height of the plain, which we can denote as h_plain and assume is zero.
At the highest point of its trajectory, the arrow will have zero vertical velocity, since it will have stopped rising and just started to fall. So we can set the velocity to zero and solve for the time it takes for that to occur. Using the formula for velocity under constant acceleration:
v = v0 + at
we can solve for t when v = 0, h0 = 3 ft, v0 = 108 ft/s, and a = -32.2 ft/s^2:
0 = 108 - 32.2t
t = 108/32.2 ≈ 3.35 s
Thus, it takes the arrow approximately 3.35 s to reach the top of its trajectory.
Using the formula for the height of an object at a given time, we can find the height of the hill by subtracting the height of the arrow at the top of its trajectory from the initial height:
h_hill = h0 + v0t + 1/2at^2 - h_top
where h_top is the height of the arrow at the top of its trajectory. We can find h_top using the formula for the height of an object at the maximum height of its trajectory:
h_top = h0 + v0^2/2a
Plugging in the given values, we get:
h_top = 3 + (108^2)/(2*(-32.2)) ≈ 196.78 ft
Plugging this into the first equation, we get:
h_hill = 3 + 108(3.35) + 1/2(-32.2)(3.35)^2 - 196.78
h_hill ≈ 25.73 ft
If the arrow is launched at t0, the equation describing velocity as a function of time would be:
v(t) = v0 - gt

For what values is the function g(x) = \(\frac{6}{x(x-7)}\) undefined?
At x = 0 and x = 7, the function g(x) is undefined.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression of the function is,
⇒ g (x) = 6 / x (x - 7)
Now, We know that;
The function f(x) = a(x) /b (x) is not defined at b (x) ≠ 0
Here, The expression of the function is,
⇒ g (x) = 6 / x (x - 7)
So, Function g (x) is not defined when,
x (x - 7) = 0
⇒ x = 0
or, x - 7 = 0
⇒ x = 7
Thus, At x = 0 and x = 7, the function g(x) is undefined.

(b) Range:
(c) Interval(s) on which f(x) is increasing:
(d) Interval(s) on which f(x) is decreasing:
(e) Interval(s) on which f(x) is constant:
(f) Local maxima: 3
(g) Local minima: -5
Answer:
a) [-9,8)
b) [-5,5]
c) (-4,0), (1,6)
d) [-9,-4), (6,8)
e) [0,1]
f) just the y-value: 5; as a point: (-8,5)
g) just the y-value: -5; as a point: (-4,-5)
Step-by-step explanation:
a) Domain is all of the x-values that are defined in the function. The smallest x-value in the graph is -9, and the largest is 8. And all values in between are defined (have corresponding y-values). But notice that there's an open dot on (8,0).
b) Range is found the same way as Domain, but with the y-values. The smallest y-value of this function is -5, and the largest is 5.
For c-e, notice where the graph changes direction and draw a vertical line from the x-axis through the turning point. These lines are the boundaries between intervals of increasing/decreasing/constant. You should have vertical lines at x=-4, x=0, x=1, and x=6.
c) Interval(s) on which f(x) is increasing: Reading the graph from Left To Right, between which vertical lines is the graph going up?
d) Interval(s) on which f(x) is decreasing: Reading the graph from Left To Right, between which vertical lines is the graph going down?
e) Interval(s) on which f(x) is constant: Reading the graph from Left To Right, between which vertical lines is the graph staying flat?
f) Look for the highest non-infinity point on the graph
g) Look for the lowest non-infinity point on the graph

B. m angle R = 81
D. m angle P = 81

Answer:
C. RP = 4.5
Step-by-step explanation:
You want to know what condition is sufficient to show ∆ABC ~ ∆QPR, given three sides and 2 angles in ∆ABC, and 2 sides in ∆QPR.
SimilaritySimilarity can be shown if all three sides are proportional, or if two angles are congruent.
The offered answer choices only list one angle, so none of those will work. The answer choice that makes the third side of ∆QPR be in the same proportion as the corresponding side of ∆ABC is the condition of interest.
C. RP = 4.5

Additional comment
The side ratios in the two triangles are ...
AB : BC : CA = 10 : 9 : 6
QP : PR : RQ = 5 : PR : 3
For these ratios to be the same, PR must be half of BC, just as the other segments in ∆QPR are half their counterparts in ∆ABC.
