f 4 8 60 28 Tentukan : a. modus data B. median data

Answers

Untuk menentukan modus data, kita mencari nilai yang paling sering muncul. Dalam kasus ini, tidak ada data yang disediakan, jadi tidak ada modus yang dapat ditentukan.

Untuk menentukan median data, kita mencari nilai tengah. Dalam kasus ini, kita memiliki 100 data, jadi median akan berada pada posisi ke-50. Dalam hal ini, median akan jatuh pada rentang 81-90.

1.
Convert the equations into the slope-intercept form y=mx+b.

$10x+5y=4 \n5y=-10x+4 \ny=-2x+(4)/(5) \nm=\boxed{-2} \Leftarrow \hbox{the slope} \n \ny=(x)/(3)-5 \ny=(1)/(3)x-5 \nm=\boxed{(1)/(3)} \Leftarrow \hbox{the slope}$

PLSSSS HELP IF YOU TULRY KNOW THISSS

Answers

Answer:

Step-by-step explanation:

Rearrange terms: -3x+4=6-3x

-3x+4=-3x+6

Subtract 4 from both sides

-3+4-4=-3x+6-4

Subtract the numbers

=3x==3x+2

Add 3x to both sides

=3x+3x=-3x+2+3x

-3x+3x=-3x+2+3x= 0=2 which is no solution

Find the area of a sector of this circle that is intercepted by a central angle measuring 30°

Answers

The area of a sector of a circle can be calculated by using this formula:

A=(n/360)*pi*r^2

where n is the measure of the central angle of the sector in degrees. Since we are already given with the measurement of the central angle, we can substitute this to the above formula:

A=(30/360)*pi*r^2

Taking the value of pi as 3.14, then

A=(1/12)*3.14*r^2
A=0.2617*r^2

Just plug in the value of r. and you will get the area of the sector. Hope this helps!
