Let u= (-1,3) and w =(2,4) Find the resulting vector of 2u-4w in component form..

IgorLugansk [536]

Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:

2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)

(4,8) - (-4,12) = (8,-4)

So the vector has the coordinates (8,-4)

What is the GCF of 72 and 36

EleoNora [17]

Answer:

Step-by-step explanation:

GCF or greatest common factor is the greater/biggest number that can factor for both numbers. To find GCF, you need to make factor of both number

72- 2 * 2 * 2 * 3 * 3 = 2^3 * 3^2

36= 2 * 2 * 3 * 3 = 2^2 * 3^2

After this, you can compare the factor of both numbers. Both numbers can be divided by 2, but 36 can be divided 2 times while 72 can be divided 3 times. In this case, you take the lowest number which is 2. Both numbers can be divided by 3^2 so you can take it whole.

The factor will be: 2^2 * 3 *2= 4 * 9= 36

Following are measurements of soil concentrations (in mg/kg) of chromium (Cr) and nickel (Ni) at 20 sites in the area of Clevela

WINSTONCH [101]

Answer:

a) see attached

b) see attached

Step-by-step explanation:

There is existence of outlier in the Ni data and there is none is Cr data.

########################################

# You can try this out in R programming

cr = c(34, 1, 511, 2, 574, 496, 322, 424, 269, 140, 244, 252, 76, 108, 24,

38, 18, 34, 30, 191)

Ni = c(23, 22, 55, 39, 283, 34, 159, 37, 61, 34, 163, 140, 32,

23, 54, 837, 64, 354, 376, 471)

par(mfrow=c(1,2))

hist(cr, col='green')

hist(Ni, col='brown')

par(mfrow=c(1,2))

boxplot(cr, main = 'Boxplot of Cr')

boxplot(Ni, main = 'Boxplot of Ni')

boxplot(cr, Ni)
