Answer: $x=1,\:x=-\frac{1}{4}$

Step-by-step explanation:

$\frac{3}{2}+\frac{1}{2x}=2x$

$\frac{3}{2}\cdot \:2x+\frac{1}{2x}\cdot \:2x=2x\cdot \:2x$

$3x+1=4x^2$

$x=1,\:x=-\frac{1}{4}$

If a seed is planted, it has a 95% chance of growing into a healthy plant. If 7 seeds are planted, what is the probability that

denpristay [2]

Answer:

$\frac{51998079}{1280000000}$ or around 0.0406

Step-by-step explanation:

We need to choose 2 seeds that will not grow - there's

7 * 6 / 2 = 21 possibilities (choose one, chose second one, divide by 2 because each choice was counted twice).

The probability of each of those possibilities happening is:

$(5\%)^2 * (95\%)^5 = \frac{2476099}{1280000000}$

because two need to fail to grow and the rest need to grow properly.

The full probability is

$\frac{51998079}{1280000000}$

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.00. They spend

Vika [28.1K]

1 large drink cost $1.65

Work: 16.95 - 12.00 = 4.95 <- Cost of drinks

Then 4.95 divided by 3 = 1.65

So it is $1.65 per large drink.

Hope I was able to help!

For which value of θ is tan θ equal to sin θ?

UkoKoshka [18]

Answer:

Step-by-step explanation:

$tan \theta=sin \theta\\tan~ \theta-sin~ \theta=0\\\frac{sin ~\theta}{cos~\theta} -sin\theta=0\\multiply ~by~cos~\theta\\sin ~\theta-sin~\theta~cos~\theta=0\\sin \theta(1-cos \theta)=0\\sin~\theta=0=sin k\pi \theta=k \pi ,where~k~is~an~integer.\\or cos\theta=1=cos 2k\pi \\\theta=2k\pi \\where~k~ is~an ~integer.\\combining\\\theta=k\pi \\where~k~is~an~integer.$
