If one row in an echelon form of an augmented matrix is left bracket Start 1 By 5 Matrix 1st Row 1st Column 0 2nd Column 0 3rd C

Step2247 [10]

Answer:

Inconsistent - TRUE

Step-by-step explanation:

A system of linear equation is said to be inconsistent if it has no solution. that is from the graph, the lines does not intersect compared to a consistent equations that has solutions and intersect on the graph.

From the written augmented matrix = ( 0)

( 0)

( 0)

( 5)

( 0)

from the second row of the matrix, it is evident that it has no solutions hence INCOSISTENT

Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d

algol [13]

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

$d_t=2d$

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

$Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days$

Now, we multiply the distance per day by the total number of days:

$Distance, D=2d\times 16\\\\=32d$

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

The probability that a randomly selected x-value from the distribution will be in the interval:

P(35 < x < 45) = 0.6827 and,
P(30 < x < 40) = 0.47725

<h3>What is the probability of a normal distribution?</h3>

The probability of a normal distribution can be determined from the symmetrical curve between 1 to 100%.

From the information given:

Mean = 40
Standard deviation = 5

To determine the probability that a randomly selected x-value is in the given interval:

P(35<x<45)
P(30<x<40)

$P(35 < x < 45) = P(\dfrac{35-40}{5} < Z < \dfrac{45-40}{5})$

$P(35 < x < 45) = P(\dfrac{-5}{5} < Z < \dfrac{5}{5})$

$P(35 < x < 45) = P(-1 < Z < 1)$

$\mathbf{P(35 < x < 45) = P[Z\le 1] -P[Z\le -1]}$

Using normal distribution table:

P(35 < x < 45) = 0.8414 - 0.1587

P(35 < x < 45) = 0.6827

$P(30 < x < 40) = P(\dfrac{30-40}{5} < Z < \dfrac{40-40}{5})$

$P(30 < x < 40) = P(\dfrac{-10}{5} < Z < \dfrac{0}{5})$

$P(30 < x < 40) = P(-2 < Z < 0)$

$\mathbf{P(30 < x < 40) = P[Z\le0]-P[Z\le -2]}$

Using normal distribution table:

P(30 < x < 40) = 0.5 - 0.02275

P(30 < x < 40) = 0.47725
