The conditional relative frequency table was generated using data that compared a student’s grade level and whether or not they

are involved in after-school activities. A 4-column table with 3 rows. The first column has no label with entries 10th grade, 11th grade, total. The second column is labeled after-school activities with entries 0. 43, 0. 55, 0. 49. The third column is labeled no after-school activities with entries 0. 57, 0. 45, 0. 51. The fourth column is labeled total with entries 1. 0, 1. 0, 1. 0. Given that a student is in 10th grade, what is the probability that the student is also not involved in after-school activities? 0. 43 0. 45 0. 55 0. 57.

The probability of the 10th-grade student is also not involved in after-school activities is 0.57.

<h2>Probability</h2>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

<h3>Statistics</h3>

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, summarise the data.

Given

A 4-column table with 3 rows.

<h3>How to find the table and the probability?</h3>

                     Activity           No Activity         Total with entries

10th                 0.43                    0.57                            1

11th                  0.55                    0.45                           1

Total                0.49                    0.41                            1

Thus, the probability of the 10th-grade student is also not involved in after-school activities is 0.57.

Lunna [17]
C) (0.85 + x/100)(250+145) does not give the correct answer.

Explanation
A) works; adding the two costs together is 250+145=395.  We multiply this by 0.85 because 100%-15%=85%=0.85.  We also have x% tax, which is represented by x/100, added to 100% of the value, or 1.00.  Altogether this gives us 
395(0.85)(1+x/100) = 395(0.85 + (0.85x/100)) = 395(0.85) + 395(0.85x/100)
= 395(0.85) + 395(0.0085x)
B) works; we have 250+145 for the original price; we have 85% = 0.85 of the value; we also have 100% + x%, which is (100+x)/100.
C) does not work; (0.85+x/100)(395) does not take into consideration that you are finding the tax after taking the 85%.  This will simplify out to
0.85*395 + (x/100)(395) = 335.75 + 395x/100 = 335.75 + 3.95x, which is too much.
D) works; simplifying the expression from A, we have 395(0.85) + 395(0.0085x) = 335.75 + 3.3575x.

I need help with # 14 and 15 ASAP... It is due tomorrow ..can some one please help me with it
Angelina_Jolie [31]

Answer:

See explanation

Step-by-step explanation:

A. Gasoline fill-up fee = $4.50

Cost per hour = $40

Average cost = C

Number of hours the scootcar is rented = h

Cost per h hours = $40h

Total cost = $40h + $4.50

Hence,

C = 40h+4.5

B. To plot the graph of the function, find h- and C- intercepts.

When h = 0, then C = 4.5, and we have point (0,4.5)

When C = 0, then 0 = 40h + 4.5, h = -45/400 = -0.1125, and we have point (-0.1125,0)

Plot these two points and connect them with a straight line.

Graph is attached, but you should take only that part of the graph that corresponds to points with h > 0, because the number of hours cannot be negative

                   c) TS


4. Answer: a) 26

                  b) 58

                  c) 21.5

                  d) 127

<u>Step-by-step explanation:</u>

2(PT) = AE              2(CP) = AN                 2(CT) = EN

2(13) = AE               2(29) = AN                  2(CT) = 43

  26 = AE                  58  = AN                      CT  = 21.5


Perimeter = AE + AN + EN

                = 26 + 58 + 43

                = 127
