Answer:

$\dfrac{5x}{x + 3}$

Step-by-step explanation:

$\begin{array}{rll}& \dfrac{25x^{2}}{2x + 6}\cdot \dfrac{2}{5x}&\\\\= & \dfrac{25x^{2}}{2(x + 3)}\cdot \dfrac{2}{5x}& \text{Factored the denominator} \\\\= & \dfrac{25x^{2}}{x + 3}\cdot \dfrac{1}{5x}& \text{Cancelled the twos} \\\\= & \dfrac{5x}{x+ 3} &\text{Cancelled the 5x}\\\\\end{array}$

Suppose that start-up companies in the area of biotechnology have probability 0.2 of becoming profitable, and that those in the

schepotkina [342]

Answer:

a) 0.03

b) 0.68

c) 0.32

Step-by-step explanation:

We are given the following in the question:

B: companies in the area of biotechnology

I: companies in the area of information technology

P(B) = 0.2

P(I) = 0.15

The two events are given to be independent.

a) P(both companies become profitable)

$P(B\cap I) = P(B)\times P(I)\\= 0.2\times 0.15 = 0.03$

0.03 is the probability that both companies become profitable

b) P(neither company becomes profitable)

$P(B'\cap I')\\=P(B')\times P(I')\\=(1-P(B))(1-P(I))\\=(1-0.2)(1-0.15)\\=0.68$

0.68 is the probability that neither company becomes profitable.

c) P(at least one of the two companies become profitable)

$P(B\cup I) = P(B) + P(I) - P(B\cap I)\\= 0.2 + 0.15 - 0.03\\=0.32$

0.32 is the probability that at least one of the two companies become profitable

Gennadij [26K]

9514 1404 393

Answer:

373 miles

Step-by-step explanation:

The difference in latitude is ...

39.1° -33.7° = 5.4° = 0.54°(π/180°) radians = 0.03π radians

The arc length is given by ...

s = rθ, where θ is the angle in radians

The length of the arc along the longitude line is ...

s = (3960 mi)(0.03π) ≈ 373 mi

The distance from Atlanta to Cincinnati is about 373 miles.

Value of x is 3.2x-9.6=38.4?

Svetradugi [14.3K]

Answer:

The steps that can be done to both sides of the equation is: Add 9.6, then divide by 3.2

Step-by-step explanation:

Solve the equation:

$3.2x - 9.6 = 38.4$

-First you add both sides 9.6:

$3.2x -9.6 +9.6 = 38.4 +9.6$

$3.2x = 48$

-Then, you divide both sides by 3.2:

$\frac{3.2x}{3.2} = \frac{48}{3.2}$

$x=15$
