To find the probability, you write a fraction with the number of expected outcomes to total possible number of outcomes.

a) Red - 25/100

b) Purple -55/100

c). There is a 25% or 1 in 4 chance to select a red bulb and a 55% or 5 in 11 chance of selecting a purple bulb.

Suppose a coefficient matrix for a system has pivot columns. Is the system​ consistent? Why or why​ not? Choose the correct answ
WINSTONCH [101]

Answer:

A. There is a pivot position in each row of the coefficient matrix. The augmented matrix will have columns and will not have a row of the form ​, so the system is consistent.

Step-by-step explanation:

Based on Godel's second incompleteness theorem, a system is considered consistent only when the far-right column of the augmented matrix is not a pivot column.

However, given that every column of the coefficient matrix is a pivot column, then there are no top coefficients in the far-right column of the augmented matrix.

Hence, there is a pivot position in each row of the coefficient matrix. The augmented matrix will have columns and will not have a row of the form ​, so the system is consistent.

Find the area of a trapezoid please help im so lost
Murrr4er [49]
Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²

Area of Trapezoid = area of rectangle + 2(area of triangle)
 = 28 + 2(10.5)
 = 28 + 21 = 49

In short, Your Answer would be 49 cm²

Hope this helps!

Solve for x in 4x-4/x+4=10
Amiraneli [1.4K]

Answer:

-22/3 =x

Step-by-step explanation:

(4x-4) /(x+4) = 10

Multiply each side by (x+4)

(4x-4) /(x+4) * (x+4) = 10 * (x+4)

(4x-4) = 10 * (x+4)

Distribute

4x-4 = 10x+40

Subtract 4x from each side

4x-4-4x = 10-4x+40

-4 = 6x+40

subtract 40 from each side

-4 -40 = 6x+40-40

-44 = 6x

Divide each side by 6

-44/6 = -6x/6

-22/3 =x
