Answer:

Let's see,

A + B = 30 (1)

A/B = 2/3 (2) => A = (2/3)*B (3)

Substitute A from (3) into (1)

=> (2/3)*B + B = 30

=> (5/3)*B = 30

=> B = 30*3/5 = 18

=> A = (2/3)*B = (2/3)*18 = 12

A ball's position, in meters, as it travels every second is represented by the position function s(t) = 4.9t2+ 350. Include unit

loris [4]

We are given the distance as a function of time:

s = 4.9 t^2 + 350

To get the velocity, we take the first derivative and substitute the value of t = 2:

ds = 9.8 t dt

ds / dt = 9.8 t

velocity = 9.8 (2)

velocity = 19.6 m/s

For the Data Set below, calculate the Variance to the nearest hundredth decimal place. (Do not use a coma in your answer) 175 34

dlinn [17]

Answer:

The variance of the data is 29966.3.

Step-by-step explanation:

The given data set is

175, 349, 234, 512, 638, 549, 500, 611

We need to find the variance to the nearest hundredth decimal place.

Mean of the data

$Mean=\dfrac{\sum x}{n}$

where, n is number of observation.

$Mean=\dfrac{3568}{8}=446$

The mean of the data is 446.

$Variance=\dfrac{\sum (x-mean)^2}{n-1}$

$Variance=\dfrac{(175-446)^2+(349-446)^2+(234-446)^2+(512-446)^2+(638-446)^2+(549-446)^2+(500-446)^2+(611-446)^2}{8-1}$

$Variance=\dfrac{209764}{7}$

$Variance=29966.2857$

$Variance\approx 29966.3$

Therefore, the variance of the data is 29966.3.
