Answer:

0.111111111 or 1/9

Step-by-step explanation:

2/3 divided by 6

keep change flip = KCF

Keep the 2/3

Flip the sign into the opposite

Change the 6 to it's reciprocal

2/3 times 1/6

multiply both the numerator, and denominator

2*1= 2 ( numerator)

3*6= 18 ( denominator)

2/18 simplify that and you get..........

1/9 as your answer

Hope this helped!

A pet store sells goldfish and hermit crabs,

Elis [28]

Answer:

$Cost = \$28$

Step-by-step explanation:

Given

Represent Goldfish with g and hermit crabs with h.

The first statement, we have:

$7g + 3h = 26$

The second statement, we have:

$4g + 5h = 28$

Required

Determine the selling price of 6 goldfish and 4 hermit crabs

The equations are:

$7g + 3h = 26$ --- (1)

$4g + 5h = 28$ --- (2)

Make g the subject in (2)

$4g + 5h = 28$

$4g = 28 - 5h$

Divide both sides by 4

$g = \frac{1}{4}(28 - 5h)$

Substitute $\frac{1}{4}(28 - 5h)$ for g in (1)

$7g + 3h = 26$

$7(\frac{1}{4}(28 - 5h)) + 3h = 26$

$\frac{7}{4}(28 - 5h) + 3h = 26$

Multiply through by 4

$4 * \frac{7}{4}(28 - 5h) + 4*3h = 26*4$

$7(28 - 5h) + 4*3h = 26*4$

Open bracket

$196 - 35h + 12h = 104$

$196 -23h = 104$

Collect Like Terms

$-23h = 104-196$

$-23h = -92$

Make h the subject

$h = \frac{-92}{-23}$

$h = \frac{92}{23}$

$h = 4$

Substitute 4 for h in $g = \frac{1}{4}(28 - 5h)$

$g = \frac{1}{4}(28 - 5*4)$

$g = \frac{1}{4}(28 - 20)$

$g = \frac{1}{4}(8)$

$g = 2$

This implies that:

1 goldfish = $2

1 hermit crab = $4

The cost of 6 goldfish and 4 hermit crabs is:

$Cost = 6g + 4h$

$Cost = 6*\$2 + 4*\$4$

$Cost = \$12 + \$16$

$Cost = \$28$

Perform the indicated operation. f(n)=n-3 g(n)=n-2 find (f+g)(6)

Grace [21]

Answer:

Step-by-step explanation:

(f + g)(n) = f(n) + g(n) = n - 3 + n - 2 = 2n - 5 , thus

(f + g)(6) = 2(6) - 5 = 12 - 5 = 7

Every day a kindergarten class chooses randomly one of the 50 state flags to hang on the wall, without regard to previous choice

Romashka [77]

Answer:

a) $S=50$

$P(X)=0.02$

b) $P(W,M,C)=8*10^-^6$

c) $P(W_2_3)=1.18*10^-^3$

Step-by-step explanation:

From the question we are told that

Sample space S=50

Sample size n=30

a)Generally the sample space S is

$S=50$

The probability measure is given as

$P(X)=\frac{1}{50}$

$P(X)=0.02$

Generally the probability that the class hangs Wisconsin’s flag on Monday, Michigan’s flag on Tuesday, and California’s flag on Wednesday is mathematically given as

Probability of each one being hanged is

$P(X)=\frac{1}{50}$

Therefore

$P(W,M,C)=\frac{1}{50} *\frac{1}{50}* \frac{1}{50}$

$P(W,M,C)=\frac{1}{125000}$

$P(W,M,C)=8*10^-^6$

c)Generally the probability that Wisconsin’s flag will be hung at least two of the three days is mathematically given as

Probability of two days hung +Probability of three days hung

Therefore

$P(W_2_3)=^3C_2 (1/50) * (1/50) * (49/50) +^3C_3 (1/50) * (1/50) *(1/50)$

$P(W_2_3)=148 / 125000$

$P(W_2_3)=1.18*10^-^3$
