Q and R are independent events. P(Q) = 0.4; P(Q AND R) = 0.08. Find P(R).
algol [13]
Because Q and R are independent, you have

\mathbb P(Q\cap R)=\mathbb P(Q)\times\mathbb P(R)
0.08=0.4\times\mathbb P(R)
\implies \mathbb P(R)=0.2

Suppose a 5x8 coefficient matrix for a system has pivot columns. Is the system​ consistent? Why and Why not?
Lyrx [107]

Step-by-step explanation:

All the 5 rows of the coefficient matrix (since it is of order 5×8) will have a pivot position. The augmented matrix obtained by adding a last column of constant terms to the 8 columns of the coefficient matrix will have nine columns and will not have a row of the form [0 0 0 0 0 0 0 0 1]. So the system is consistent.

The area of a square can be tripled by increasing the length and width by 10 inches. What is the original length of the square?
trapecia [35]
The new square has length: 10 + l, where l is the original length of the square, and it's area is (10 + l)^2;
So, we solve the equation: 3 x l^2 = (10 + l)^2;
Then, 3 x l^2 = 100 + 20 x l + l^2;
Finally, 2xl^2 - 20xl - 100 = 0;  / ÷2;
l^2 - 10l - 50 = 0 (we use the quadratic equation formula);
The only positive solution is l = 5(1+ \sqrt{3} );

Factor. 3x2 + 20x + 25​
algol [13]

Answer:

(3 x + 5) (x + 5)

Step-by-step explanation:

Factor the following:

3 x^2 + 20 x + 25

Hint: | Factor 3 x^2 + 20 x + 25 by finding factors of 3×25 whose sum is 20.

Factor the quadratic 3 x^2 + 20 x + 25. The coefficient of x^2 is 3 and the constant term is 25. The product of 3 and 25 is 75. The factors of 75 which sum to 20 are 5 and 15. So 3 x^2 + 20 x + 25 = 3 x^2 + 15 x + 5 x + 25 = 5 (3 x + 5) + x (3 x + 5):

5 (3 x + 5) + x (3 x + 5)

Hint: | Factor common terms from 5 (3 x + 5) + x (3 x + 5).

Factor 3 x + 5 from 5 (3 x + 5) + x (3 x + 5):

Answer: (3 x + 5) (x + 5)
