A bag contains 4 red marbles, 8 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probabili

mina [271]

Answer:

The probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Step-by-step explanation:

Number of red marbles = 4

Number of blue marbles = 8

Number of Green marbles = 2

Total number of marbles = 4+8+2 =14

We need to find the probability, to the nearest 10th of a percent, that both marbles drawn will be red?

The formula used will be: $Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\$

In our case, Number of favourable outcomes = 4 (as red marbles are drawn)

Number of possible outcome = 14 (Total number of marbles)

The probability will be:

$Probability=\frac{Number\:of\:favourable\:outcomes}{Number\:of\;possible\:outcomes}\\\\Probability=\frac{4}{14}\\ Probability=0.2857\\$

Now, calculating nearest 10th of a percent

$Probability = 0.2857*100\\Probability=28.5%$

So, the probability, to the nearest 10th of a percent, that both marbles drawn will be red is 28.5%

Answer:

C. $225,000

Step-by-step explanation:

The utilization for each department must be at most the available capacity. Each product quantity must be non-negative.

You could almost guess the answer here because the profit on product C is so much higher than for the others.

Profit is maximized by producing as much of product C as possible. That quantity is limited by the assembly hours constraint: 2C ≤ 30,000. This permits production of 15,000 units, so gives a profit of ...

$15·15,000 = $225,000 . . . maximum profit

Find the value of c so that (x-2) is a factor of the polynomial p(x)

blagie [28]

Answer:

Step-by-step explanation:

$\text{If}\ (x-a)\ \text{is a factor fo polynomial}\ w(x),\ \text{then}\ a\ \text{is a root of plynomial}\ w(x):\\\\w(a)=0.\\\\\text{We have}\\\\\text{the polynomial}\ p(x)=x^3-4x^2+3x+c\\\\\text{the factor of the polyniomial}\ p(x):(x-2)\\\\x=2\ \text{is the root of polynomial}\ p(x).\ \text{Therefore we have the equation:}\\\\2^3-4(2^2)+3(2)+c=0\\8-4(4)+6+c=0\\8-16+6+c=0\\-2+c=0\qquad\text{add 2 to both sides}\\c=2$
