Answer:

Graph below

Step-by-step explanation:

Transformations

Triangle ABC has coordinates A=(-4,2) B=(-2,6) C=(3,2)

We'll use the transformation (x,y) -> (2x, y+3) to map it to the triangle A'B'C'. Let's calculate the coordinates:

A'=(-8,5)

B'=(-4,9)

C'=(6,5)

The image below shows both triangles in the same grid

There are 4,000 undergraduates registered at a certain college. Of them, 364 are taking one course, 496 are taking two courses,

kykrilka [37]

Answer:

X=1, P = 0.091

X=2, P = 0.124

X=3, P = 0.115

X=4, P = 0.378

X=5, P = 0.264

X=6, P = 0.028

Step-by-step explanation:

To calculate the probability distribution of X, first we have to define the sample space.

In this case X=1,2,3,4,5,6. This are the values that X can take.

The probability is calculated as equal to the relative frequency of each of the values.

For X=1, P = 364/4000 = 0.091

For X=2, P = 496/4000 = 0.124

For X=3, P = 460/4000 = 0.115

For X=4, P = 1512/4000 = 0.378

For X=5, P = 1056/4000 = 0.264

For X=6, P = 112/4000 = 0.028

If a and b are two angles in standard position in Quadrant I, find cos(a+b) for the given function values. sin a=4/5 and cos b=5

vladimir1956 [14]

First let's find the angles a and b.

We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.

cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.

We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.

What is the value of x in the equation-2/9 x =2/5?

erik [133]

Answer: x = 9/5 or x = 1 4/5

Step-by-step explanation:

2/9 x = 2/5

2/9 * 9/2 * x = 2/5 * 9/2

x = 2/5 * 9/2

x = 9/5 = 1 4/5
