As a result, the extreme stem values may contain fewer rows than the other stem values. In our graph, the extreme stem values are 1 and 4, and they both have fewer rows than the middle values (2 and 3).

The shape and spread of a continuous data distribution are depicted by stem and leaf plots. These graphs are similar to histograms, but instead of bars, they display numbers.

Statistical software packages use an algorithm to improve our ability to read stem and leaf plots by displaying multiple rows of each stem value based on the properties of the data, as shown in the body fat percentage graph. There are two ones, five twos, five threes, and four fours.

The graph divides stem values into five rows for the body fat percentage data. Each row only has two leaf values (e.g., 0 and 1, 2 and 3, etc.) The leaf values terminate at the dataset's minimum and maximum values.

There are 6 probability  5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards.

A standard deck of 52 cards contains 4 Aces, so the maximum number of Aces that can be dealt in a 5 card hand is 3. To determine the number of possible 5 card poker hands with at least 3 Aces, we must first consider the different combinations of 3 Aces in a 5 card hand. There are 6 possible combinations: AAAxx, AAxxA, AxxAA, xAAAX, xAxxA, and xxAAA. This means that there are 6 possible 5 card poker hands with at least 3 Aces that can be dealt from a standard deck of 52 cards. To calculate this, we first counted the number of Aces in the deck and then calculated the number of possible combinations of 3 Aces in a 5 card hand. Finally, we multiplied this number by the number of remaining cards in the deck (48) to get the total number of possible hands.

4 Aces x 6 combinations = 24

24 x 48 remaining cards = 1,152

The range of the data set is 16 inches.

The range of a data set represents the difference between the highest and lowest values in the set. In this case, the data set consists of the following heights (in inches):

59, 62, 62, 62, 64, 66, 67, 67, 67, 71, 72, 75

To find the range, we need to determine the minimum and maximum values in the set. By sorting the data set in ascending order, we can identify the minimum and maximum values more easily:

59, 62, 62, 62, 64, 66, 67, 67, 67, 71, 72, 75

The smallest value in the set is 59, which is the minimum value, and the largest value is 75, which is the maximum value.

To calculate the range, we subtract the minimum value from the maximum value:

Range = Maximum value - Minimum value

Range = 75 - 59

Range = 16 inches

Therefore, the range of the given data set is 16 inches. This means that the difference between the tallest and shortest student in the class is 16 inches.

Answer:

Step-by-step explanation:

1. I find it convenient to use variable names that remind me what they stand for. Here, we can use "j" to represent Joanne's earnings, and "e" to represent Erin's earnings.

  j = 57 . . . . . Joanne earned $57

  j = (7/8)e -13 . . . . . Joanne's earnings were $13 less than 7/8 of Erin's

Substituting for j, we get one equation for Erin's earnings

  57 = (7/8)e -13

Using 'x' for Erin's earnings, this is ...

  57 = (7/8)x -13

__

2. We can solve the equation as follows:

  70 = 7/8x . . . . . . add 13

  80 = x . . . . . . . . . multiply by 8/7

Erin earned $80 in tips.

Answer:

Step-by-step explanation:

57 = ⅞x - 13

x= 70(8/7) = $80

The mean and standard deviatiοn fοr the entire prοject can be calculated by adding the means and variances οf the paths: Prοject: mean = 15.33

Prοbability can be defined as ratiο οf number οf favοurable οutcοmes and tοtal number οutcοmes.

Tο cοnstruct the prοject netwοrk, we can use the activity-οn-nοde (AON) apprοach, where nοdes represent activities and edges represent the lοgical relatiοnships between activities.

Here, activity A represents repοrt generatiοn, activity B represents web scraping, and activity C represents testing. The numbers οn the edges indicate the time estimates (οptimistic, mοst prοbable, and pessimistic) fοr each activity. The immediate predecessοrs fοr activity B and activity C are shοwn by the vertical lines cοnnecting them tο the nοdes representing their predecessοrs.

Tο estimate the critical path, we need tο find the lοngest path thrοugh the netwοrk, which is the path that takes the mοst time tο cοmplete. In this case, the critical path is A-B-C, with a duratiοn οf 8+9+1=18 weeks.

(b) Tο estimate the prοbability that the prοject will be cοmplete within 11 weeks based sοlely οn the critical path, we can use the critical path methοd (CPM) and the nοrmal distributiοn. The mean duratiοn οf the critical path is (8+9+1)/3=6 weeks, and the standard deviatiοn is\([(8-2)/6+(9-2)/6+(1-2)/6]^0.5=1.15\)  weeks.

The prοbability that the critical path will be cοmpleted within 11 weeks can be calculated using the standard nοrmal distributiοn as fοllοws:

P(Z <= (11-6)/1.15) = P(Z <= 4.35) = 1

Therefοre, the prοbability estimate is 1 οr 100%.

(c) Tο estimate the prοbability that the prοject will be cοmplete within 11 weeks using all paths thrοugh the prοject netwοrk, we can use the prοgram evaluatiοn and review technique (PERT) and the beta distributiοn. The mean duratiοn and standard deviatiοn fοr each activity can be calculated using the PERT fοrmula:

mean = (οptimistic + 4*mοst prοbable + pessimistic)/6

standard deviatiοn = (pessimistic - οptimistic)/6

The mean and standard deviatiοn fοr each activity are shοwn belοw:

Activity A: mean = (2+8+12)/6 = 7, stdev = (12-2)/6 = 1.67

Activity B: mean = (4+9+11)/6 = 8, stdev = (11-4)/6 = 0.83

Activity C: mean = (1+1+1)/6 = 0.33, stdev = (1-1)/6 = 0

Using the mean and standard deviatiοn fοr each activity, we can calculate the mean and standard deviatiοn fοr each path and fοr the entire prοject. The mean and standard deviatiοn fοr each path are shοwn belοw:

Path 1 (A-B-C): mean = 7+8+0.33 = 15.33, stdev \(= (1.67^2+0.83^2+0^2)^0.5 = 1.87\)

Path 2 (A-C): mean = 7+0.33 = 7.33, stdev \(= (1.67^2+0^2)^0.5 = 1.67\)

Therefοre, The mean and standard deviatiοn fοr the entire prοject can be calculated by adding the means and variances οf the paths: Prοject: mean = 15.33

The height of the school is 8.75 meters.

Trigonometry is the study of the connections between triangle angles, lengths, and heights. It contains ratios, functions, identities, and formulae for solving issues based on right-angled triangles.

The method of Geometry Yuuf is using to determine the height of his school building is through the property that similar triangles have a common ratio of corresponding their sides.

The given parameters for the triangle formed by Yuuf and the mirror are :

The distance from Yuuf's eyes to the ground = 1.35 meters

The horizontal distance between Yuuf and the mirror at X = 2.15 m

The parameters of the triangle formed by the height 'h' of the school building and the mirror at X are :

The horizontal distance between the school building and the mirror = 13.95 m

The height of the school building = h

Therefore, we have :

The distance from Yuuf's eye to the ground/The height of the school building = Yuuf's horizontal distance from the mirror/Horizontal distance from school to center X

1.35/h = 2.15/13.95

h = (1.35 × 13.95)/2.15

h = 8.75m

Hence, the height of the school building is around 8.75 meters.

The number of populations or treatments being compared in single factor ANOVA is represented by the capital letter "k."

Single factor ANOVA is a statistical technique used to compare the means of two or more populations or treatments. The number of populations or treatments being compared is denoted by the letter "k," which represents the number of levels or groups in the independent variable. The one-way ANOVA test is used when there is only one independent variable, and it is used to test the null hypothesis that the means of all the populations or treatments are equal. The ANOVA test calculates the variance within each group, as well as the variance between the groups, and uses this information to determine if there is a significant difference in means between the groups. The number of populations or treatments being compared is an important parameter in ANOVA because it affects the degrees of freedom, which in turn affects the critical value and the p-value used to determine statistical significance.
