what is the value of x​

Answer: chart b

Step-by-step explanation:

2 is only a product of the outcomes 1/18 times

3 is only a product of the outcomes 1/18 times

4 is only a product of the outcomes 1/12 times

5 is only a product of the outcomes 1/18 times

6 is only a product of the outcomes 1/9 times

and so on

The chart that shows the probability distribution for the sum of the two numbers is chart B.

It is a branch of mathematics that deals with the occurrence of a random event.

When two dice are rolled, 36 equally likely outcomes are possible

The sum of the 36 outcomes are as follows: 2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12

The number of the sums are as follows:

n(2) = 1

n(3) = 2

n(4) = 3

n(5) = 4

n(6) = 5

n(7) = 6

n(8) = 5

n(9) = 4

n(10) = 3

n(11) = 2

n(12) = 1

The probability of the sums are given as follows:

p(2) = 1/36

p(3) = 2/36 = 1/18

p(4) = 3/36 = 1/12

p(5) = 4/36 = 1/9

p(6) = 5/36

p(7) = 6/36 = 1/6

p(8) = 5/36

p(9) = 4/36 = 1/9

p(10) = 3/36 = 1/12

p(11) = 2/36 = 1/18

p(12) = 1/36

Therefore, the chart that shows the probability distribution for the sum of the two numbers is chart B.

Step-by-step explanation:

Just Multiply 9.8 and 7.6

Answer:

74.48

Step-by-step explanation:

9.8x7.6= 74.48

All you need to do is line up the numbers and multiply like normal if you get a ten or higher it will go to the next number up

Answer:

a) The probability of both chips being good = 0.48

b) The probability of both chips being bad = 0.24

c) The probability of one chip being good = 0.60

Step-by-step explanation:

Probability of first chip being good = 3/5 = 0.60

Probability of second chip being good = 4/5 = 0.80

Probability of first chip being bad = 0.40 or 2/5 (1 - 3/5)

Probability of second chip being good if the first is bad = 2/5 = 0.4

Therefore, the probability of it being bad = 0.60 (1 - 0.40)

For both chips to be good, the probability = 0.60 * 0.80 = 0.48

For both chips to be bad, the probability = 0.60 * 0.40 = 0.24

Answer:

The answer to this question can be defined as follows:

i) [tex]\bold{p(x)= -5x^2+ 217x- 1,401} \\[/tex]

ii) x=22 units

iii) Maximum profit: 953.45

Step-by-step explanation:

Given value:

p(x) = 211 − 5x \\

C(x) = 1,401 + 16x

The formula for calculating the profit function value:

[tex]\to \bold{P(x)= xp(x) - C(x)}[/tex]

             [tex]= x(211-5x)- 1,401 + 16x\\\\= 211x -5x^2-1,401+16x\\\\= -5x^2+ 217x- 1,401 \\[/tex]

The formula for calculating the value for maximum profit:

[tex]p'(x) = - 10x + 217 =0[/tex]

[tex]217= 10x\\\\x= \frac{217}{10}\\\\x= 21.7[/tex]

So, the production level is 22 units

Maximum profit:

[tex]\to p(21.7)= - 5 (21.7)^2+217 (21.7) -1,401\\\\[/tex]

           [tex]=-5 (470.89) +217 (21.7) -1,401\\\\=-2354.45+ 4708.9-1,401\\\\= 953.45[/tex]

The maximum monthly revenue of WidgCo is; $489

price function; p(x) = 211 - 5x

Cost function; C(x) = 1401 + 16x

Revenue = number of units sold × price per unit

Thus;

R(x) = x(211 - 5x)

Expanding this gives;

R(x) = 211x - 5x²

R'(x) = 211 - 10x

At R'(x) = 0, we have;

211 - 10x = 0

x = 211/10

x = 21.1

x ≈ 21 widgets

Maximum Revenue is;

R(20) = 195(21) - 1401 - 5(21)²

R(20) = $489

Answer:$4.90

Step-by-step explanation:

Answer:

Step-by-step explanation:

If for a cup of water, 1/3 cup of salt is needed, to get the number of gallons of water needed for 6 cups of salt, we will use the following equation;

1/3 cup of salts = 1 cup of water

6 cups of salt = x cups of water

cross multiply

1/3 * x= 6*1

x/3 = 6

multiply both sides by 3

x/3 * 3 = 6*3

x = 18

Hence 6 cups of salt will need 18 gallons of water

Answer:

100,000

Step-by-step explanation:

Answer:

It should be $2,900

Step-by-step explanation:

First you convert the percentage to decimal form out of 100

3%/100 = 0.03

A = P(1 + rt)

A = 2000(1 + 0.03 x 15)

Which you should get $2,900 or $2,900.00 (which is pretty much the same thing)

===========================================================

Explanation:

Cube values in the set {0,1,2,3,...} until we reach a result larger than 497

We stop here because 512 is larger than 497.

Or you could note that [tex]\sqrt[3]{497} = 497^{1/3} \approx 7.921[/tex] helping us see that we stop at 8.

The list of nonnegative perfect cubes less than 497 is {0,1,8,27,64,125,216,343}

There are 8 items in that set out of 498 items in the set {0,1,2,3,...,497}

So the probability of getting a perfect cube is 8/498 = 4/249

Answer:

eight

Step-by-step explanation:

The scale factor of ΔABC to ΔDEF is 8. Hence, option B is the right choice.

The scale factor between two figures (any dimensions) is the scale to which the original figure (preimage) is multiplied to make the transformed figure (image).

In ΔABC and ΔDEF,

AB/DE = BC/EF = CA/FD (Corresponding sides of triangle are in ratio)

∴ ΔABC ~ ΔDEF (SSS axiom)

The scale factor = A side of ΔDEF/Corresponding side of ΔABC = DE/AB = 48/6 = 8.

∴ The scale factor of ΔABC to ΔDEF is 8. Hence, option B is the right choice.
