Answer 1

Answer:

Option (D)

Step-by-step explanation:

Given expression is,

x³ × 3 ÷ [tex]\frac{2}{9}[/tex] + 9x - (7 - 6x)

By substituting x = [tex]\frac{2}{3}[/tex],

[tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})][/tex]

By using rule PEMDAS,

P - Parenthesis

E - Exponent

M - Multiplication

D - Division

A - Addition

S - Subtraction

[tex]=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4][/tex]

= [tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3[/tex]

= [tex]\frac{8}{27}\times 3 \div \frac{2}{9}+6-3[/tex]

= [tex]\frac{8}{9}\div \frac{2}{9}+6-3[/tex]

= [tex]\frac{8}{9}\times \frac{9}{2}+6-3[/tex]

= 4 + 6 - 3

= 7

Option (D) is the answer.

Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.

Answers

Answer:500

Step-by-step explanation:

There are 100 production runs from each plant should be ordered to minimize the cost.

What is Production?

The process of making or manufacturing goods and products from raw materials or components is called Production.

The Macon plant produce 1 ton of LP and 3 tons of HP in single operation, and it charge $600 for what is produced in one operation.

And, One operation of Jonestown plant produce 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation.

And, A customer needs at least 100 tons of LP and 180 tons of HP,

Now, A graph of the requirements shows the feasible region is bounded by a polygon with vertices (Macon and Jonestown) as,

= (0, 180), (40, 60), (100, 0).

Hence, By checking costs of these solutions, we find the lowest cost to be obtained when 100 production runs should be ordered from Macon.

So, There are 100 production runs from each plant should be ordered to minimize the cost.

Step-by-step explanation:

Recall that an American Roulette wheel has 38 possible outcomes, 18 black, 18 red and 2 green. The numbers go from 1 to 36, and the green outcomes are numbered 0 and 00. Someone places 10 bets on "1st 12", that is, that person wins if the outcome is any number between 1 and 12, included. 1. (2pts) What is the probability of losing a ’1st 12’ bet on a single spin? 2. (3pts) What is the probability of winning 7 out of the 10 total bets?

Answers

Answer:

American Roulette

1. The probability of losing a  ’1st 12’ bet on a single spin is:

= 0.67

2. The probability of winning 7 out of the 10 total bets is:

= 0.23

Step-by-step explanation:

Possible outcomes in an American Roulette wheel = 38

Make-up of the outcomes = 18 black, 18 red and 2 green

Green outcomes are numbered 0 and 00

Number of wins for this person = 12

Probability of winning = 0.33  (12/36)

Number of possible losses for this person = 24

Probability of losing = 0.67 (24/36)

1. The probability of losing a  '1st 12' bet on a single spin is:

= (36 - 12)/36

= 0.67

2. The probability of winning 7 out of the 10 total bets is:

Probability of winning = 12/36 * 7/10

= 0.23

Find the values of the variable and the lengths of the sides.

4x + 12 - 5 < 5x + 7

4x + 7 < 5x + 7

Collect like terms

4x - 5x < 7 - 7

-x < 0

Divide both sides by -1

x > 0

17. 24 > -3x

Divide both sides by -3

24/-3 < -3x/-3

-8 < x

x > -8

18. -5(2x - 6) + 3x < 2(2x + 1) - 11x

-10x + 30 + 3x < 4x + 2 - 11x

Answer:

B and C

Step-by-step explanation:

Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.

A minimum point occurs where all the nearby values are higher than that of the point in question.

A maximum point occurs where all the nearby points are lower than the point in question.

By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)

By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.
