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

Calculate the sample mean and sample variance for the following frequency distribution of heart rates for a sample of American adults. If necessary, round to one more decimal place than the largest number of decimal places given in the data. Heart Rates in Beats per Minute Class Frequency 51 - 58 6 59 - 66 3 67 - 74 11 75 - 82 13 83 - 90 4
Answer:
[tex]Mean = 68.9[/tex]
[tex]s^2 =18.1[/tex] --- Variance
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Class} & {51-58} & {59-66} & {67-74} & {75-82} & {83-90} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.
[tex]x = \frac{1}{2}(51+58) = \frac{1}{2}(109) = 54.5[/tex]
For 59 - 66
[tex]x = \frac{1}{2}(59+66) = \frac{1}{2}(125) = 62.5[/tex]
For 67 - 74
[tex]x = \frac{1}{2}(67+74) = \frac{1}{2}(141) = 70.5[/tex]
For 75 - 82
[tex]x = \frac{1}{2}(75+82) = \frac{1}{2}(157) = 78.5[/tex]
For 83 - 90
[tex]x = \frac{1}{2}(83+90) = \frac{1}{2}(173) = 86.5[/tex]
So, the table becomes:
[tex]\begin{array}{cccccc}{x} & {54.5} & {62.5} & {70.5} & {78.5} & {86.5} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
The mean is then calculated as:
[tex]Mean = \frac{\sum fx}{\sum f}[/tex]
[tex]Mean = \frac{54.5*4+62.5*3+70.5*11+78.5*13+86.5*4}{6+3+11+13+4}[/tex]
[tex]Mean = \frac{2547.5}{37}[/tex]
[tex]Mean = 68.9[/tex] -- approximated
Solving (b): The sample variance:
This is calculated as:
[tex]s^2 =\frac{\sum (x - \overline x)^2}{\sum f - 1}[/tex]
So, we have:
[tex]s^2 =\frac{(54.5-68.9)^2+(62.5-68.9)^2+(70.5-68.9)^2+(78.5-68.9)^2+(86.5-68.9)^2}{37 - 1}[/tex]
[tex]s^2 =\frac{652.8}{36}[/tex]
[tex]s^2 =18.1[/tex] -- approximated

(a+b)^2≥4ab
Mark as brainlist___________________________________
Answer:
(a+b) ²≥4ab explanation below↓↓↓↓
Step-by-step explanation:
We know that
(a-b) ²≥0
a²-2ab+b²≥0
Move -2ab to the other side
a²+b²≥2ab
Add 2ab to both sides
a²+2ab+b²≥4ab
(a+b) ²=a²+2ab+b² therefore :
(a+b) ²≥4ab

I need friends...I wanna talk to someone
Answer:
17
Step-by-step explanation:
BODMAS
3(9)-12+2
27-12+2
27-10
17
Answer:
17
Step-by-step explanation:
You add what's inside the parenthesis, then rewrite the equation once more, (3)(9)-12+2, then you gotta multiply 3*9 which is 27. Rewrite the equation again, 27-12+2, then you must subtract 27 from 12 which is now 15. So now we're left with 2, 15+2 is 17. If it makes it any easier, think of this equation as losing friends and gaining friends, and now you're left with 17 now.
What is the difference of 78−13?
Answer:
65
Step-by-step explanation:
The line is parallel to y = -3x - 2 and passes through the point (-4, 3)
Answer:
y = -3x - 9
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m -> slope & b ->y-intercept
y = -3x - 2
So, slope of the required line = -3
(-4 , 3)
y - y1 = m(x - x1)
y - 3 = -3(x - [-4])
y - 3 = -3(x + 4)
y - 3 = x*(-3) + 4*(-3)
y - 3 = -3x - 12
y = -3x -12 + 3
y = -3x - 9

HELPPP I NEED TO DO THIS BEFORE 7:00
Answer:
A, (13/3 x 5/13)
Step-by-step explanation:
So first, you should change the mixed numbers into improper fractions. To convert, just multiply the whole number by the denominator and add the numerator. Do that to both fractions and you should get 13/3 ÷ 13/5. Since you need to switch to multiplication, switch the sign and flip that fraction/ That asnwer is 13/3 x 5/13. Hope that helps! :)
Lasian invests £9200 into a bank account. She receives 5% per year compound interest. How much money does she have after 11 years?
Answer:
the money after 11 years is £15,735.12
Step-by-step explanation:
The computation of the amount after 11 years is given below:
Future value = Present value × (1 + rate of interest)^number of years
= £9,200 × (1 + 0.05)^11
= £9,200 × 1.05^11
= £9,200 × 1.710339358
= £15,735.12
Hence, the money after 11 years is £15,735.12

George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. He followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24.
Step 1: Find the total cars needed to have a mean of 24: 24 times 7 = 168.
Step 2: Find the total cars sold: 18 + 22 + 26 + 12 + 25 + 20 + 19 = 142.
Step 3: Subtract the total cars sold from the total cars needed: 168 minus 142 = 26.
Step 4: State the answer: George needs to sell 26 cars next month.
Where did George make his first mistake?

The equation 2d + 18 = 24 can help find the number of days Jerry has been doing sit-ups.
Step-by-step explanation:
During the first day, Jerry did 18 sit-ups, and he proceeded to do 2 more sit-ups each following day, so the expression to represent this situation is 2d + 18. Because he did 24 sit-ups today, to find the number of days he did sit-ups, the equation to solve is 2d + 18 = 24.
