Maria, an experienced shipping clerk, can fill a certain order in 9 hours. Jim, a new clerk, needs 11 hours to do the same job. Working together, how long will it take them to fill the order
Answer:
4 19/20 hours or 4 hours , 57 minutes
Step-by-step explanation:
Given
In 9 hours Maria can fill a certain order let Say X
In 9/9 hours Maria can fill X/9 of the order
in 1 hour Maria can fill X/9 of the order
__________________________________
In 11 hours Jim can fill a certain order let Say X
In 11/11 hours Maria can fill X/11 of the order
in 1 hour Maria can fill X/11 of the order
_____________________________________________
Therefore total order filled by them in one hour will sum of individual work done by them in one hour.
Mathematically,
total order filled by Jim and maria in one hour = work done by Jim in one + work done by Maria in one hour
total order filled by Jim and maria in one hour = 1/11 + 1/9
=> [tex]1/11 + 1/9 \\=> (9 + 11)/11*9\\=> 20/99[/tex]
=>20/99 of certain order is filled by both of them in one hour.
=>Total order is one. Hence, to get 1 from 20/99 we need to multiply it with its reciprocal (i.e 99/20) as 20/99 *99/20 = 1
now
=>20/99 of certain order is filled by both of them in 1 hour.
=>multiplying both order and hour with 99/20 we have
20/99 *99/20 of certain order is filled by both of them in 1* 99/20 hour
Thus total order is filled by them in 99/20 hours = 4 19/20 hours.
1 hour has 60 minutes
so 19/20 has 60*19/20 minutes = 57 minutes.
Working together, Jim and Maria will take 4 hours , 57 minutes to fill the order.

The area of a square garden is 100 square meters.
a. Find the length of each side of the garden.
? m area = 100 m2
b. Find the perimeter of the garden.
Please help
Answer:
a. The length of each side of the garden is 10 m.
b. The perimeter of the garden is 40 m.
Step-by-step explanation:
A square is a regular polygon with four sides. The area of a square is given by the formula
[tex]Area = width \cdot height[/tex]
But since the width and height are by definition the same, the formula is usually written as
[tex]Area = s^2[/tex]
where s is the length of one side.
a. To find the length of each side of the garden we know that the area is 100 [tex]m^2[/tex] applying the area formula and solving for s, the length of one side, we get that
[tex]100=s^2\\\\s^2=100\\\\\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}\\\\s=\sqrt{100},\:s=-\sqrt{100}[/tex]
The length can't be negative. Therefore, [tex]s=\sqrt{100}=10[/tex]
b. In the case of a square, all four sides are the same length, so the perimeter is four times the length of a side. Or as a formula:
[tex]Perimeter = 4s[/tex]
where s is the length of any one side.
We find that the length of each side is 10 m. Therefore, the perimeter is
[tex]Perimeter = 4s\\\\Perimeter =4 \cdot 10 = 40 \:m[/tex]
What is x if the equation is, 4 - (2x-3) = 3?
Answer:
x = 2
Step-by-step explanation:
4 - (2x-3) = 3
Distribute the minus sign
4 -2x+3 = 3
Combine like terms
7 -2x = 3
Subtract 7 from each side
7 -2x-7 = 3-7
-2x = -4
Divide by -2
-2x/-2 = -4/-2
x = 2

Coopers & Lybrand surveyed 210 chief executives of fast-growing small companies. Only 51% of these executives had a management succession plan in place. A spokesperson for Cooper & Lybrand said that many companies do not worry about management succession unless it is an immediate problem. However, the unexpected exit of a corporate leader can disrupt and unfocus a company for long enough to cause it to lose its momentum. Use the data given to compute a 92% confidence interval to estimate the proportion of all fast-growing small companies that have a management succession plan.
Answer:
92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.
(0.46154 , 0.558)
Step-by-step explanation:
Given sample size 'n' = 210
The sample proportion 'p' = 51% = 0.51
Confidence intervals are determined by
[tex](p^{-} - z_{\alpha } \sqrt{\frac{p^{-} (1-p^{-} }{n} } , p^{-} +Z_{\alpha } \sqrt{\frac{p^{-} (1-p^{-} )}{n } } )[/tex]
The 92% of z-score value
[tex]Z_{\frac{\alpha }{2} } = Z_{\frac{0.08}{2} } = Z_{0.04} = 1.405[/tex]
92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.
[tex](0.51 - 1.405 \sqrt{\frac{0.51 (1-0.51 }{210} } , 0.51 +1.405 \sqrt{\frac{0.51 (1-0.51)}{210 } } )[/tex]
on calculation , we get
(0.51-0.048 , 0.51 + 0.048)
(0.46154 , 0.558)
Final answer:-
92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

Sporting Equipment, Inc. makes two types of balls: Soccer balls and Cork balls. The making of each soccer ball and cork ball requires 3 hours and 4 hours of production time, respectively. For the next month, the total production hours of 500 are available. Also, the combined production quantity for these two balls must be at least 150 units. The objective for this linear programming model is to fulfil the given production requirements at a minimum cost. The production cost for each Soccer ball is S7 and each Cork ball is $9.
1. Formulate the problem, using the following decision variables:
S = number of Soccer balls manufactured
C = number of Cork balls manufactured
2. The objective function is:
A. Maximize 9S + 7C
B. Minimize 7S + 9C
C. Minimize 9S + 7C
D. Maximize 7S + 9C
3. The constraint equation for the production hours is:
A. 3S + 4C >= 500
B. 4S + 3C <= 500
C. 4S + 3C <= 500
D. 3S + 4C <= 500
4. The constraint equation for the combined production quantity is:
A. S + C <= 150
B. S + C >= 150
C. S + C = 150
D. S + C =/150
5. If the company produces 100 soccer balls and 50 cork balls, the cost of production is:
a. $1250 b. $1350 c. $1150 d. $2000
Answer:
2) B). Minimize 7S + 9C
3) D) . 3S + 4C ≤ 500
4) B). S + C ≥ 150
5) C) $1150
Step-by-step explanation:
The company makes two types of balls, the balls and their costs are written below:
Soccer ball, S = $7
Cork ball, C = $9
Production time of each ball:
Soccer ball = 3 hours
Cork balls = 4 hours
2) To find the objective function.
Since the cost of each soccer ball is $7 and S balls are produced, the total cost of soccer balls is 7S.
Similarly, the cost of each cork ball is $9 and C balls are produced, total cost is 9C.
The objective function maximize profits and minimizes losses. Here, the objective for this linear programming model is to fulfil the given production requirements at a minimum cost.
Therefore the objective function here is: Minimize 7S+9C
3)The constraint equation for the production hours.
To produce one soccer ball, 3 hours are needed, i.e 3S, to produce one Cork ball 4 hours are needed, i.e 4C.
Since we are given a maximum productin time of 500 hours, the constraint equation for the production hours would be:
3S + 4C ≤ 500
4) Since we are told the combined production quantity for these two balls must be at least 150 units, the constraint equation for the combined production quantity is:
S + C ≥ 150
5)Since each soccer ball costs $7, 100 soccer balls would cost:
7*100 = $700
Similarly, since each Cork ball costs $9, 50 cork balls would cost:
9*50 = $450
Therefore the total cost of production would be:
$700 + $450 = $1,150

The following are the ages (years) of 5 people in a room: 25, 18, 17, 13, 24 A person enters the room. The mean age of the 6 people is now 22. What is the age of the person who entered the room?
Answer:
See Below:
Step-by-step explanation:
Average is take by adding all the terms together and dividing by the number of terms. In this case it terms is people in the room.
22= (25+18+17+13+24+x)/6
Where 22 is the average age. The numerator is all the known ages added together, plus x which is the age of the person who just entered. Divided by 6 because you are finding the average age of 6 people.
22 = (25+18+17+13+24+x)/6 Multiply both sides by 6
132= 97+ x Subtract 97 from both sides.
35 = x
The person who just entered the room is 35 years old.

Seaside Bike Shop rents bikes for $10 plus $4 per hour. Jack paid $30 to rent a bike. Which equation, when solved for x, gives the number of hours he rented the bike?
You don’t list the options but you need to multiply the hourly rate by the number of hours (x) and add that to the few to find the total so the equation would be:
Total = 4x +10
You are told the total was $30 so you can solve for x:
30 =3x + 10
Subtract 10 from both sides:
20 = 4x
Divide both sides by 4:

An immigration agent sampled cars going from country M to country N. In his report, he indicated that of the 85 cars sampled, 27 cars were driven by women, 53 cars were driven by citizens of country M, 41 cars had two or more passengers, 23 cars were driven by women who are citizens of country M, 22 cars were driven by women and had two or more passengers, 18 cars were driven by citizens of country M and had two or more passengers, and 13 cars were driven by women who are citizens of country M and had two or more passengers. After his supervisor reads the report, she explains to the agent that he made a mistake. Explain how his supervisor knew that the agent's report contained an error.
Answer:
the numbers of women drivers are inconsistent
Step-by-step explanation:
Let W, C, P stand for the conditions that the drivers were women, the drivers were citizens, and the car had passengers, respectively.
We are told the number of WCP cars is 13, the number of WC cars is 23, and the number of WP cars is 22. The total of WC and WP cars counts WCP cars twice, so the total of cars in these three categories combined is ...
WC +WP -WCP = 23 +22 -13 = 32
This number (32) is more than the total number of cars with women driving (27), so there is obviously a mistake.
