miskamm [114]
The area of a triangle is base x height x (1/2)
Plug in the values that are given.
Area = 10 x 12 x (1/2)
Area = 120 x (1/2)

Area = 60 in²

Hope this helps :)

PLS ANSWER ALL QUESTIONS TO YOUR FULLEST EXTENT, IF YOU DO NOT UNDERSTAND PLS ASK ON THE COMMENTS, DO NOT USE AN ANSWER TO ASK,
ololo11 [35]

Answer:

pls give me brainliest

Step-by-step explanation:

A compound event is an event where there are more than 1 type of possibilities. for example, a non compound event like tossing a coin, has only 2 outcomes, either heads or tails, this is one possibility, but while tossing a die, there are various possibilities, like p(getting 1), p(getting even number), p(getting prime number), etc. this is known as a compound event.

a sample space is is where all outcomes of an event is enlisted, for example in tossing a die, sample space is {1,2,3,4,5,6}. and sample space for tossing a coin, {H,T}. Note : if 2 dices are tossed, the number of possibilities or 6^2, because there are 6 possibilities in one die and it will be 6^2 if there are 2.

a tree diagram helps in easily writing down the outcomes easily, here is an example.

Determine if the statement is true or false, and justify your answer. Suppose A is a matrix with n rows and m columns. If n &lt;
Natali5045456 [20]

Answer:

The question is incomplete as there are given options ;

Q:

Determine if the statement is true or false , and justify your answer . Suppose A is a matrix with n rows and m columns . If n < m, then the columns of A span R True, since there are more columns than rows. O False, since there are not enough columns to span R". True, since every column of A must be a nonzero column, False, since every column of A may be a zero column, True, since every column of A must be a non zero column, False, since every column of A may be a zero column

Step-by-step explanation:

Considering a matrix A with n-rows and m-columns,

given that n is less than m i.e the rows is less than the columns

then the columns of A span Rn? TRUE OR FALSE?

the matrix is of nxm as n is less than m, hence from linear transformation, T will span : Rm towards Rn

the concept of ranking of a matrix is applied here as ranking entails the  number of linearly independent rows or columns vectors in a matrix, in this case

the order is n x m where n is less than m, as such the rank of the matrix is n

So, Rank of MATRIX A is n

To prove if the rows vectors are linearly independent or not since n is the rank of the matrix

In this case, m columns vector will be considered with respect to n which is the rank and which is also less than m from the conditions, as such there exist a linearly independent relationship between them which R may be spanned since we know that from ranking, reduction to echelon form comes into play by trying to reduce every element of the column A to zero.

  • Trying to reduce to echelon form implies all the element of column A may or may not zero.

from the foregoing, the last option is the correct answer ; False, since every column of A may be a zero column

Expression related to -1/3(6x+15)-3
marshall27 [118]

Answer:

x = -4 and -2x - 8

Step-by-step explanation:

<u>Step 1:  Distribute</u>

-1/3(6x + 15) - 3

-6/3x - 15/3 - 3

-2x - 5 - 3

-2x - 8

<u>Step 2:  IF NEEDED SOLVE FOR X</u>

-2x - 8 + 8 = 0 + 8

-2x / -2 = 8 / -2

x = -4

Answer:  x = -4 and -2x - 8
