Answer:

x = 30

Step-by-step explanation:

well the two agnles are congruent so they have to equal the same angle

x+ 90 = 4x

solve for x bye subtracting x from 90

90 = 3x slove by dividing 90 by 3 getting x alone

90/3 = x

Which statement implies that A and B are independent events?
STatiana [176]

Answer:

P(A \cap B) = P(A)P(B)

Step-by-step explanation:

Independent events:

If two events, A and B are independent, the probability of both A and B happening is the same as the probability of A happening multiplied by the probability of B happenings, that is:

P(A \cap B) = P(A)P(B)

In this question:

The statement is P(A \cap B) = P(A)P(B)

You are planning to make a collage and are gathering materials.for the backing you will use a piece of heavy recycled cardboard
Lunna [17]
1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields 
\frac{19}{4} * \frac{12}{5} =
=  \frac{57}{5} = 11.4 ft^{2}

Part 2: 
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:
\frac{69}{10} / \frac{3}{8} =  \frac{69}{10} * \frac{8}{3} =  \frac{92}{5}
since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is 18 cutouts

The equation of the graph shown plotted in the coordinate plane is y = x + 4. What statement is not true about this graph? A. Ea
frez [133]

Definately option C

  • As it's mentioned y=x+4 it must be function
  • So in function every domain has its unique range.
  • Hence here the slope is not constant

As

The graph shown is a parabola which is not y=x+4

So option C is wrong
