Komok [63]

Answer: B and C only

Step-by-step explanation:

The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and rises 4 degrees

Initial temperature = 0

Temperature rise = 4

Fall in temperature = - 4

(Initial temperature + rise in temperature + fall in temperature)

Summing all : (0 + 4 - 4) = 0

carbon atom has 6 negatively charged electrons and 6 positively charged protons.

Net charge of atom :

(number of proton + number of electrons)

( 6 + (-6)) = 0

The heights of women aged 30 to 35 are approximately Normal with mean 63 inches and standard deviation 2.4 inches. Men the same

gavmur [86]

Answer

given,

mean of women (μ)=63 inches

standard deviation of women (σ)= 2.4 inches

mean of men (μ)=70 inches

standard deviation of women (σ)= 2.5 inches

for women

$P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

using z-table

$P(x>66)= 1 - 0.8944$

$P(x>66)=0.1056[/tex]for men[tex]P(x>66)$

$P(x>66) = 1-P( \dfrac{x - \mu}{\sigma}$

$P(x>66) = 1-P( z$

using z-table

$P(x>66)= 1 - 0.0548$

$P(x>66)=0.9452$

Determine by inspection whether the vectors are linearly independent. Justify your answer.

jekas [21]

Answer:

B. The set is linearly independent because at least one of the vectors is a multiple of another vector.

Step-by-step explanation:

A set of n vector of length n is linearly independent if the matrix with these vectors as column has none of zero determinant. The set of vectors is dependent if the determinant is zero. In the given question the vectors have no zero determinants therefore it is linearly independent.
