3. Greater than

Median is the middle number of the data set. But in this senario, there are 2 numbers in the middle. So you can take 4+5/2=4.5

To find Mean, you can must take all the numbers in the data set divided by the number of data collected.

In this case, (3+3+4+5+5+9)÷6

You will find that the mean is greater than the median.

The area of a triangle is 1/2(base)(height) and since this is a right triangle the two legs can be base and height. So the area is 1/2(2x-4)^2 which becomes 1/2(4x^2-16x+16) which is simplified to 2x^2-8x+8. B is the correct answer.

Two drivers, Alison and Kevin, are participating in a drag race. Beginning from a standing start, they each proceed with a const
Vilka [71]

Answer:

Alison wins against Kevin by 0.93 s

Step-by-step explanation:

Alison covers the last 1/4 of the distance in 3 seconds, at a constant acceleration a_a, we have the following equation of motion

s/4 = a_at_a^2/2

where s (m) is the total distance, ta = 3 s is the time

s = 4a_a3^2/2 = 18a_a

a_a = s/18

Similarly, Kevin overs the last 1/3 of the distance in 4 seconds, at a constant acceleration a_k, we have the following equation of motion:

s/3 = a_kt_k^2/2

tk = 4 s is the time

s = 3a_k4^2/2 = 24a_k

a_k = s/24

Since a_a = s/18 we can conclude that a_a > a_k, so Alison would win.

The time it takes for Alison to cover the entire track

s = a_aT_a^2/2

T_a^2 = 2s/a_a = 2s/(s/18) = 36

T_a = \sqrt{36} = 6 s

The time it takes for Kevin to cover the entire track

s = a_kT_k^2/2

T_k^2 = 2s/a_k = 2s/(s/24) = 48

T_a = \sqrt{48} = 6.93 s

So Alison wins against Kevin by 6.93 - 6 = 0.93 s

Step-by-step explanation:

1. (a-b-c) (a2+b2+c2-ab-ac-bc). = (a3-b3-c3).

NOTE : this is an identity 11th identity

2. (98)3

That is 98×98×98= 941192

For example. (1)3

That is 1×1×1= 1

Or (2)3

That is 2×2×2= 8. [ 2×2=4. ]. {4× 2 = 8 )

a circle has a radius of 4. an arc in this circle has a central angle of 288. what is the length of the arc?
anzhelika [568]

Answer:20.096

Step-by-step explanation:

radius =r=4

Φ=288

π=3 14

Length of arc=Φ/360 x 2 x π x r

Length of arc=288/360 x 2 x 3.14 x 4

Length of arc=0.8 x 2 x 3.14 x 4

Length of arc=20.096
