Do you ever feel like you did something good that well finally make your mom proud but then she finds somthing bad and says alll

Volgvan

Answer:

Step-by-step explanation:

It usually is easier for people to see the bad rather than the good. Stop trying to make her proud and work for you because it seems like she just has her expectations way too high. And comparing you to a sibling? No one is the same, and she has no right to do that. Don't give up love. Move at your own pace, despite what your mom says.

1.) The island shown has a population of 12,175 people. Find the population

miv72 [106K]

Answer:

Population density = $148.22\ \text{people per square kilometer}$

Step-by-step explanation:

The attached figure shows the dimension of an island.

Population density is equal to total population per unit land area.

Firstly we will find the area of the triangle using Pythagoras theorem as follows :

$H^2=B^2+P^2$

H is Hypotenuse, B is base and P is perpendicular

$B=\sqrt{H^2-P^2} \\\\B=\sqrt{(18.5)^2-(11.1)^2} \\\\B=14.8\ km$

Area of triangle is given by :

$A=\dfrac{1}{2}\times b\times P\\\\A=\dfrac{1}{2}\times 14.8\times 11.1\\\\A=82.14\ km^2$

$\text{Population density}=\dfrac{\text{Total population}}{\text{land area}}\\\\=\dfrac{12175 }{82.14}\\\\=148.22\ \text{people per square kilometer}$

Hence, the population density is $148.22\ \text{people per square kilometer}$ .

Which type of graph is typically not used for quantitative data?

Verdich [7]

Answer:

A histogram often looks similar to a bar graph, but they are different because of the level of measurement of the data. Bar graphs measure the frequency of categorical data. A categorical variable is one that has two or more categories, such as gender or hair color

In how many different ways can 3 identical green shirts and 3 identical red shirts be distributed among 6 children such that eac

VARVARA [1.3K]

Answer:

Total number of ways will be 20

Step-by-step explanation:

We have given three identical green shirts and three identical red shirts

So total number of shirts = 3+3 = 5

We have to distribute these shirts to 6 children so that each children got one shirt

Number of ways will be equal to $=\frac{6!}{3!3!}=20$ ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )
