Answer:
A ton is 2,000 pounds, so the answer is 24 Tons
Answer:
24 tons
Step-by-step explanation:
1 ton = 2,000 pounds
[tex]\frac{1}{2,000} :\frac{y}{48,000}[/tex]
y × 2,000 = 48,000 × 1
2,000y = 48,000
2,000y ÷ 2,000 = 48,000 ÷ 2,000
y = 24

You tell your 3 friends that you are going to a magic show. It turns out, in an amazing coincidence, they each
have tickets to the same magic show. The dissapointing part is that all 4 of you are sitting in different places at
the event. During the show, the magician asks for 4 brave volunteers. If you and all of your friends raise your
hands as well as 16 other audience members for a grand total of 20 volunteers.
What is the probability that you and your 3 friends will be selected. Write your answer as a simplified
fraction.
Answer:
[tex]\frac{1}{4845}[/tex] probability that you and your 3 friends will be selected.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the volunteers are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
You and the 3 friends(4 people), from a set of 4. So
[tex]D = C_{4,4} = \frac{4!}{4!0!} = 1[/tex]
Total outcomes:
20 people from a set of 20. So
[tex]T = C_{20,4} = \frac{20!}{4!16!} = 4845[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{4845}[/tex]
[tex]\frac{1}{4845}[/tex] probability that you and your 3 friends will be selected.

You want to open a checking account at your local bank which offers two options. A standard checking account charges $6 each month plus $.25 for each check written. A select checking account charges $4.50 each month plus $.50 for each check written. Which system of equations can be used to determine the number x of checks that must be written in a month in order for the total charges y for the two checking accounts to be the same?
Answer:
The total charges for the two checking accounts will be the same after 6 checks written.
Step-by-step explanation:
Since I want to open a checking account at my local bank which offers two options, a standard checking account that charges $ 6 each month plus $ 0.25 for each check written, and a select checking account that charges $ 4.50 each month plus $ 0.50 for each check written, to determine which system of equations can be used to determine the number X of checks that must be written in a month in order for the total charges Y for the two checking accounts to be the same, the following calculation must be performed:
6 + 0.25X = Y
4.5 + 0.5X = Y
6 + 0.25x5 = Y
4.5 + 0.5x5 = Y
6 + 1.25 = Y = 7.25
4.5 + 2.50 = 7
6 + 0.25x6 = Y
4.5 + 0.5x6 = Y
6 + 1.50 = Y = 7.50
4.5 + 3 = 7.50
Therefore, the total charges for the two checking accounts will be the same after 6 checks written.

Suppose that 50% of the watches produced by a certain factory are defective. A store buys a box with 400 watches produced by this factory. Assume That this is a random sample.(a) Write an expression for the exact probability that at least 215 watches out ofthe 400 are defective. You do not need to numerically evaluate it.(b) Argue whether the normal or the Poisson approximation is appropriate to es-timate the above probability and then estimate it.
Answer:
[tex](a)\ P(x \ge 215)[/tex]
[tex](b)\ P(x \ge 214.5) = 0.07353[/tex]
Step-by-step explanation:
Given
[tex]p = 0.50[/tex] ---- proportion of watches with defects
[tex]n = 400[/tex] --- Number of watches
Solving (a): Represent at least 215 of 400 are defective
In inequalities, at least means: [tex]\ge[/tex]
So, the probability is represented as: [tex]P(x \ge 215)[/tex]
Solving (b): Calculate [tex]P(x \ge 215)[/tex]
Normal or Poisson: Normal distribution is characterized by 2 parameters [tex]\mu[/tex] and [tex]\sigma[/tex].
These two parameters can be easily calculated from the given parameters in the question. So, we solve using normal distribution
Start by calculating the mean
[tex]\mu =np[/tex]
[tex]\mu = 0.50 * 400[/tex]
[tex]\mu = 200[/tex]
Calculate standard deviation
[tex]\sigma = \sqrt{\mu (1 - p)[/tex]
[tex]\sigma = \sqrt{200 * (1 - 0.50)[/tex]
[tex]\sigma = \sqrt{200 * 0.50[/tex]
[tex]\sigma = \sqrt{100[/tex]
[tex]\sigma = 10[/tex]
By continuity correction, we have:
[tex]x \to x - 0.5[/tex]
[tex]x \to 215 - 0.5[/tex]
[tex]x \to 214.5[/tex]
So, we have:
[tex]P(x \ge 215) = P(x \ge 214.5)[/tex]
Calculating [tex]P(x \ge 214.5)[/tex], we have:
[tex]P(x \ge 214.5) = 1 - P(x < z)[/tex]
Calculate z score
[tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]z = \frac{214.5 - 200}{10}[/tex]
[tex]z = \frac{14.5}{10}[/tex]
[tex]z = 1.45[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - P(x < 1.45)[/tex]
Using the z score probability table, we have:
[tex]P(x < 1.45) = 0.92647[/tex]
So, we have:
[tex]P(x \ge 214.5) = 1 - 0.92647[/tex]
[tex]P(x \ge 214.5) = 0.07353[/tex]
write the equation for a parabola with a focus at (-3,-5) and a directrix at x=-7
x=
Answer:
hope this helps
Step-by-step explanation:
equation for a parabola is:
What is parabola?The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus.
Given: focus= (3,-5), directrix at x =-7.
To find equation of parabola we will use distance formula,
√(x+7)²=√(x+3)² + (y+5)²
(x+7)²=(x+3)² + (y+5)²
x²+14x+49= x²+9+6x + (y+5)²
8x + 40 = (y+5)²
x= (y+5)²/8 -5
Hence, the equation of parabola is x= (y+5)²/8 -5

Josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester. She wants to know what she needs to earn on the last test to maintain her grade. Rearrange the following equation for b, where C is the average of 2 test scores, a and b.
C equals the quantity a plus b all over two
b equals two times C over a
b = 2C + a
b = 2C − a
b = 2C(a)
Answer:
Hi i know im very late answering this question but i believe the correct option is: b = 2C - a
Step-by-step explanation:
I believe this is the answer because:
2C = the average of 2 test scores combined
A and B = the two scores
were trying to solve for b so what we would do to figure that out is have the average of both test scores and then subtract A which will leave you with only B. therefor the answer is B = 2C - a

A cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height. Using 3.14 for pi, which of the following can be
used to calculate the volume of the cylinder? (6 points)
Answer:
The volume of the cylinder is 6,104.16 square meters.
Step-by-step explanation:
Given that a cylinder has a height of 6 meters and a diameter that is 6 times the measure of the height, to determine, using 3.14 for pi, which of the following can be used to calculate the volume of the cylinder, the following calculation must be done, knowing that the volume of a cylinder is determined by multiplying Pi by the height by the radius squared, and that the diameter of a circle is twice its radius:
3.14 x 6 x (6x3) ^ 2 = X
18.84 x 18 ^ 2 = X
18.84 x 324 = X
6,104.16 = X
Therefore, the volume of the cylinder is 6,104.16 square meters.

Based on the scores of these two tests for the five candidates, who would you select as a finalist. Please note that you need to use the method we used in class to find out the finalist for selection. Describe the answer with the appropriate calculations as we did in the exercise in class.
Answer: Hi your question is incomplete below is the missing part
Candidate Interviewscore Job Knowledge Test Score
Frank. 14 89
Sally 21 77
Lilly 20 75
Peter 17 82
Jordyn 19 80
Answer : Select Sally because she has the highest Test score
Step-by-step explanation:
For Franck :
Interview score / 25 = 14 / 25 = 0.56
Job knowledge score = 89 /100 = 0.89
Test score = 0.56 + 0.89 = 1.45
For Sally
interview score = 21 / 25 = 0.84
Jon knowledge = 77 / 100 = 0.77
Test score = 0.84 + 0.77 = 1.62 ( Highest test score )
Repeat the same procedure for Lilly , Peter and Jordyn
Lily test score = 1.55
Peter test score = 1.5
Jordyn test score = 1.56
conclusion : select Sally as a Finalist
