In 2001, a total of 15,555 homicide deaths occurred among males and 4,753 homicide deaths occurred among females. The estimated

deff fn [24]

Answer:

a. 11

b. 3

c. homicide mortality rate

d. 11:3

Step-by-step explanation:

a.) If 15,555 homicide cases were recorded among males of 139,813,000 population, then in every 100,000 males, the number of homicides cases will become:

= [15,555/139,813,000] * 100,000

= 11.13 aproximately 11 homicide cases in every 100,000 males.

b.) If 4,753 homicide cases were recorded among Females of 144,984,000 population, then in every 100,000 Females, the number of homicides cases will become:

= [4753/144,984,000] * 100,000

= 3.28 approximately 3 homicide cases in every 100,000 females

C.) Homicide-mortality rate

d.) ratio of male to female homicide rate = 11 : 3

e.) What those rates means is that in every 100,000

Males in 2001, 11 of them were Victims of homicide and in every 100,000 females, 3 of them are victims of homicide.

Mr. Walker asked his students to use the associative property to find an expression that is equivalent to (13 + 15 + 20) + (20 +

kaheart [24]

Answer:

The correct option is four.

Step-by-step explanation:

The associative property implies that the values are added however we want, i.e. the numbers can be grouped in any way and the answer would still be the same.

The associative property of addition is:

$(a+b)+c=a+(b+c)$

The expression provided is:

(13 + 15 + 20) + (20 + 47 + 18)

The answer provided by four students are:

Jeremy : (20 + 13 + 15) + (20 + 47 + 18)

Layla : (20 + 47 + 18) + (13 + 15 + 20)

Keith : (13 + 20) + (20 + 47 + 18) + 15

Melinda : (13 + 15 + 20 + 20) + (47 + 18)

So, all the four students correctly applied only the associative property to rewrite the expression.

The correct option is four.

Express the vector r~ a b c d p r in terms of a~ , b~ , c~ , and d~ , the edges of a parallelogram.

Gre4nikov [31]

Given the vector $\vec{r}(a,b,c,d)$ .

Now taking the vertices of parallelogram asA $\vec{a},B\vec{b},C\vec{c},D\vec{d}$ .

As we know to find the edges of parallelogram ABCD,we proceed as follows

$\vec{AB}$ = Position vector of B - Position vector of A

$\vec{b}-\vec{a}$

$\vec{BC}$ = Position vector of C - Position vector of B

= $\vec{c}-\vec{b}$

$\vec{CD}$ = Position vector of D - Position vector of C

= $\vec{d}-\vec{c}$

$\vec{DA}$ = Position vector of A - Position vector of D

= $\vec{a}-\vec{d}$

So, $\vec{b}-\vec{a},\vec{c}-\vec{b},\vec{d}-\vec{c},\vec{a}-\vec{d}$ are edges of parallelogram.

The Animal World Safari Park is a rectangular piece of land with an area of 323 square miles. The length of the park is 17 miles

Charra [1.4K]

The area of a rectangle is A = L * W. We have the area as 323 and the length as 17. Filling in our formula for area then, 323 = 17W. Divide both sides by 17 to solve for the width. W = 19
