Answer:

30

Step-by-step explanation:  Find the prime factorization of 6

6 = 2 × 3

Find the prime factorization of 30

30 = 2 × 3 × 5

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the lcm:

LCM = 2 × 3 × 5

LCM = 30

Multiples of 6: 6, 12, 18, 24, 30

Multiples of 30: 30, 60, 90, 120

The smallest number that is common to both lists is the LCM.

So, what number is found on both lists and is the smallest?

I see 30. Do you see 30 on both?

Answer: 30

A company manufactures and sells x television sets per month. The monthly cost and​ price-demand equations are ​C(x)=72,000+60x
myrzilka [38]

Answer:

Step-by-step explanation:

Given

Cost Price c(x)=72000+60x

Price p(x)=300-\frac{x}{20}

Revenue generated R(x)=P(x)\times x

where x=no of units

R(x)=300x-\frac{x^2}{20}

To get maxima and minima differentiate R(x)

\frac{\mathrm{d} R(x)}{\mathrm{d} x}=0

\frac{\mathrm{d} R(x)}{\mathrm{d} x}=300-2\times \frac{x}{20}=0

300=2\times \frac{x}{20}

x=3000

maximum Revenue R(x)=(300-\frac{300}{20})\times 300=4,50,000

(b)Profit=Revenue - cost

Profit=xp(x)-c(x)

Profit=300x-\frac{x^2}{20}-72000-60x

Profit(z)=240x-\frac{x^2}{20}-72000

differentiate Profit to get maximum value

\frac{\mathrm{d} z}{\mathrm{d} x}=240-2\times \frac{x}{20}

x=2400

maximum Profit z=2,16,000

(c)Now company decided to tax the company $ 55 for each set

Profit (z_1)=xp(x)-c(x)-55x

z_1=300x-\frac{x^2}{20}-72000x-60x^2-55x

z_1=185x-\frac{x^2}{20}-72,000

differentiate Profit to get maximum value

\frac{\mathrm{d} z_1}{\mathrm{d} x}=0

\frac{\mathrm{d} z_1}{\mathrm{d} x}=185-\frac{2x}{20}=0

x=1850

P(z_1\ at\ x=1850)=99125

company should charge 207.5 $ for each set

What is the X values such that y equals 15 - 3 X and Y equals 0 question
Oksana_A [137]
X=5. this is true because if y=0 and y=15-3x, then 15-3x=0. if x is 5, it would be 15-3(5)=0.

How would i solve a problem like this?
SVETLANKA909090 [29]

The number of combinations of size k that you can make with n items is given by the so-called binomial coefficient,

\dbinom nk = \dfrac{n!}{k!(n-k)!}

• n! is the number of ways of permuting n items.

• (n-k)! is the number of ways of permuting all but k of the n items.

Dividing n! by (n-k)! then gives the number of ways of permuting only k of the total n items.

• k! is the number of ways of permuting k items.

Dividing \frac{n!}{(n-k)!} by k! then removes all those permutations which contain the same items. We call these combinations.

For this problem we only care about counting combinations.

There are

\dbinom 63 = \dfrac{6!}{3!(6-3)!} = 20

ways of selecting any 3 girls from the total 6 girls in the entire group of people.

There are

\dbinom 72 = \dfrac{7!}{2!(7-2)!} = 21

was of selecting any 2 boys from the total 7 boys.

Then there are

\dbinom 63 \dbinom 72 = 20\cdot21 = \boxed{420}

ways of choosing a committee of 5 people consisting of 3 girls and 2 boys.

If the next question were, "What is the probability that a committee of 5 randomly selected people consists of 3 girls and 2 boys?", then you would additionally need to compute the number of ways one can make a committee of 5 people from the total 13, which is

\dbinom{13}5 = \dfrac{13!}{5!(13-5)!} = 1287

Then the probability of selecting such a committee at random is

\dfrac{\binom 63 \binom72}{\binom{13}5} = \dfrac{420}{1287} = \dfrac{140}{429} \approx 0.3263
