Answer:

A= 21.65063509

Step-by-step explanation:

triangle area is =base*hight/2

Because we have a right triangle we can apply the trigonometric functions

sin30 =base/hypothenuse = base/10

cos 30 = hight/hypothenuse =hight/10

sin30 = base /10  ; multiply both sides by 10

base = 10*sin30

cos 30 = hight /10 ; multiply both sides by 10

hight = 10 cos 30

A= 10*sin30*10*cos30/2 =

      100*sin 30*cos 30/2=

            50*sin30*cos30 = ; use calculator make sure is set up in degrees

A= 21.65063509

Write a paragraph comparing the two classes' semester grades. Be sure to compare the extremes, the quartiles, the medians, and t
NISA [10]

Answer:

Class second have higher score and have greater spread.

Step-by-step explanation:

For first box plot

\text{Minimum value }= 53

Q_1=62

Median=80

Q_3=86

\text{Maximum value }= 89

Range=Maximum-Minimum=89-53=36

IQR=Q_3-Q-1=86-62=24

For second box plot

\text{Minimum value }= 56

Q_1=62

Median=74

Q_3=89

\text{Maximum value }= 96

Range=Maximum-Minimum=96-56=40

IQR=Q_3-Q-1=89-62=27

First class has greater minimum value, it means first class has lower grades.

First quartile of both classes are same, it means equal number students in both classes have less than 62 marks.

First class has greater median.

second class has greater third quartile.

Second class has greater Maximum value.  It means second class have higher score than first class.

Second class has greater range. It means the data of second class has greater spread.

Second class has greater inter quartile range.  It means the data of second class has greater spread.

Therefore, the class second have higher score and have greater spread.

Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.
baherus [9]

Answer:

\boxed{y=-2x+5}

Step-by-step explanation:

The equation in slope-intercept form is given by:

y=mx+c

where m is the slope and c is the y-intercept.


The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through (x_1,y_1)= (1,3) and (x_2,y_2)=(2,1).

The slope is given by;

m=\frac{y_2-y_1}{x_2-x_1}.


\Rightarrow m=\frac{1-3}{2-1}.


\Rightarrow m=\frac{-2}{1}=-2.

The y-intercept from the graph is c=5


Our equation finally becomes;

y=-2x+5
