3. At the school festival, you can win a bicycle by pulling a red bull out of the bag. The first bag has 52 white balls, 27 green balls, and 11 red balls. The second bag has 25 white balls, 25 green balls, 25 yellow balls, and 10 red balls.

a. What are the odds of pulling a red ball from the first bag?
b. What are the odds of pulling a red ball from the second bag?

Answers

Answer 1

a) The Odds of  pulling a red ball from the first bag is; 12.2%

b) The Odds of  pulling a red ball from the second bag = 10/85 = 0.1176 = 11.76%

What is the probability of selection?

We are given;

Number of white balls in first bag = 52

Number of green balls in first bag = 27

Number of red balls in first bag = 11

Total number of balls in first bag = 52 + 27 + 11 = 90 balls

Number of white balls in second bag = 25

Number of green balls in second bag = 25

Number of red balls in second bag = 10

Number of yellow balls in second bag = 25

Total number of balls in second bag = 25 + 25 + 10 + 25 = 85 balls

a) Odds(probability) of  pulling a red ball from the first bag = 11/90 = 0.122 = 12.2%

b) Odds(probability) of  pulling a red ball from the second bag = 10/85 = 0.1176 = 11.76%

Answers

Actual area of bedroom is bigger than the kitchen as per the given measurements and scale.

As per the given question,

Given drawing scale is:

1 : 30

Shape of the kitchen is rectangle with measurements = 12cm by 27cm

Using scale :

Length = 12cm

Actual length = 12 × 30

                      = 360cm

Width = 27cm

Actual width = 27 × 30

                     = 810 cm

Actual area of kitchen = 360 × 810

                                     = 291,600 cm²

Actual area of bedroom = 300,000cm²

300,000 > 291,600

Actual area of bedroom > Actual area of kitchen

Therefore, actual area of bedroom is bigger than the actual area pf kitchen.

The complete question is:

a spring has a spring constant of 283 n/m. how far is the spring compressed to the right if 129 n of force are used

Answers

The spring is compressed to 95.5 cm to the right if 129 N of force are used.

In this question, we have been given the spring constant k = 283 N/m

if 129 N of force are used then we need to find distance  that the spring compressed to the right.

Let the spring stretch from the equilibrium position x.

An equation for the spring's potential energy is,

PE = 1/2 ​kx^2

129 = 1/2 * 283 * x^2

2 * 129 = 283 * x^2

258/283 = x^2

x^2 = 0.9117

x = 0.9548 m

x = 95.5 cm

Therefore, the spring is compressed to 95.5 cm to the right if 129 N of force are used.

Express the formula d=rt in terms of the time,t. Use your formula to find the time when the distance is 40 and the rate is 8.

Answers

The expression for  d=rt in terms of the time is t = d/r; t = 5.

What is time? Time can be defined as a continuous and ongoing  sequence of events that occur consecutively from the past to the present to the future. Time is used to  measure, measure or compare the duration of events or the intervals between them, and even the sequence of events. Time is a useful concept that we use in our daily life. We have to watch when we cook, play, study, go to school, meet someone, etc. So knowing the right time is very important. Time is usually the answer to when an event happens or  happened. The concept of time determines when a certain event occurs, has occurred or will occur. Time is a measurable quantity and is also infinite. The time is calculated in seconds, minutes, hours, days, months and years.

Therefore,

In the equation d=rt

                          t = d/r

when distance is 40 and the rate is 8

                          t = d/r

Replace d with 40 and rate with 8

ABCD is a rectangle, where AB= x cm and
BC is 1.5 cm less than AB.
If the area of the rectangle is 52 cm³, form
an equation in x and solve it to find the
dimensions of the rectangle.

Answers

Answer:

AB = 8cm ; BC = 6.5 cm

Step-by-step explanation:

BC = x- 1.5


x * (x-1.5) = 52

x^2 - 1.5x - 52 = 0

Discriminant = 2.25 -4(-52) = 2.25 + 208 = 210.25

We are searching only positive value

(1.5 + 14.5)/2 = 16 / 2 = 8 cm


AB = 8 cm

BC = 8 - 1.5 = 6.5 cm

In statistics, the process of hypothesis testing involves putting an analyst's presumption about a population parameter to the test.

The type of data being used and purpose of the study will determine the methodology the analyst uses. A basic hypothesis can anticipate a causal relationship between variables, i.e., that one has an impact on the other. This is known as hypothesis testing, and it uses sample data to determine the plausibility of a hypothesis.It is a technique for analysis that evaluates presumptions and establishes the likelihood of something based on a predetermined level of accuracy. Testing hypotheses offers a technique to determine whether the outcomes of an investigation are reliable.

The completed statement on the exponential model that fits the data in the question is presented as follows;

The exponential model indicates that the plastic production has a 7.88% growth per year. The model predicts that the production 15 years after 1960 was closest to 30 million metric tons, because the correlation coefficient indicates a strong correlation between the model and the data, this prediction is correct.

What is a correlation coefficient?

The correlation coefficient is an indication of the level at which the variables are interdependent.

The table of values in the question can be entered into a spreadsheet application as follows;

In the spreadsheet application, enter Year since 1960 values in a column, and the Plastic Production in an adjacent columnSelect the all the data entered into the spreadsheet document such as MS Excel, then select the Insert tabIn the charts section select scatter plot to create a scatter plot of the dataIn the Design tab, that appears when the chart is selected, select the Add Chart Element button access the Trendline functionSelect the Exponential trendline from the menu for trendlinesThe exponential trendline is then created by the spreadsheet application

The equation for the trendline obtained from MS Excel is presented as follows; f(x) = 9.2179·e^(0.0788·x)

The growth rate from the above exponential function is 7·88% per year

The production 15 years after 1960 is therefore;

f(15) = 9.2179·e^(0.0788 × 15) ≈30.06

The number of plastic produced 15 years after 1960 is about 30 million metric tons

The correlation coefficient obtained from MS Excel is R² = 0,9157, which indicates a strong correlation between the data and the model

The prediction is correct based on the strong correlation between the year and the number of plastic produced.

I need help please im so confused

Answers

Step-by-step explanation:

the x-intercept is the point, where the curve intercepts the x-axis (that means y = 0).

the y-intercept is the point, where the curve intercepts the y-axis (that means x = 0).

y = 10 - 2x

when x = 0, that means y = 10 - 2×0 = 10.

when y = 0, that means 0 = 10 - 2x, 2x = 10, x = 5

x-intercept = (5, 0)

y-intercept = (0, 10)

4y + 9x = 18

x = 0, 4y = 18, y = 18/4 = 9/2 = 4.5

y = 0, 9x = 18, x = 18/9 = 2

x-intercept = (2, 0)

y-intercept = (0, 4.5)

6x - 2y = 44

3x - y = 22

x = 0, -y = 22, y = -22

y = 0, 3x = 22, x = 22/3 = 7 1/3

x-intercept = ( 7 1/3, 0)

y-intercept = (0, -22)

2x = 4 + 12y

x = 2 + 6y

x = 0, 6y = -2, y = -2/6 = -1/3

y = 0, x = 2 + 6×0 = 2

x-intercept = (2, 0)

y-intercept = (0, -1/3)
