Answer:

\(\frac{3}{10}\)

Step-by-step explanation:

The multiplies of 3 from 1-20 are:

3, 6, 9, 12, 15, 18

Since there are \(20-1+1=20\) numbers from 1-20 inclusive, the probability that a ball is a multiple of 3 is \(\frac{6}{20}=\boxed{\frac{3}{10}}\)

Answer:

$122.1

Step-by-step explanation:

We are given the following data in the question

$124, ​$256 ​, $118, ​$441, ​$122, ​$335, ​$340, ​$191

Step 1

Find the mean

Mean = Sum of Terms / Number of Terms

Number of Terms = 8

Mean = ($124 + $256 ​+ $118 + ​$441 + $122 + ​$335 + ​$340 + ​$191 )/ 8

Mean = $1927/8

= $240.875

Approximately to 1 decimal place

$240.9

Step 2

Standard deviation formula

S = √( x - μ)²/ N - 1),

N = Number of terms

μ = Mean

S = √[($124 - $240.9)² + ($256 - $240.9)² + ($118 - $240.9)² + (​$441 - $240.9)² + ($122 - $240.9)² + ​($335 - $240.9)² + ​($340 - $240.9)²+ ​($191 -$240.9)²/ 8 - 1]

S = $122.0895

Approximately to 1 decimal place

S = $122.1

Therefore, the standard deviation for the given data is $122.1

Answer

6 and 2/3 percent of an hour OR 6.666.... hour

I don’t know if you have to round or not but if it does just round

Step-by-step explanation:

Well 4 minutes of an hour is basically 4/60

4/60=1/15

1/15=x/100

solve the proportion by cross multiplying

Answer:

Area = 113.04 in^2

Step-by-step explanation:

you have the diameter which is twice the radius, the formula is in the question:

Area = πr^2

so

12: 2 = 6 (RADIUS)  

Area = π6 ^ 2 =

Area = π 36 in^2

Area = 3.14 * 36

Area = 113.04 in^2

At the 5% significance level, we have sufficient evidence to conclude that the population mean is higher than 40 hours.

To test the null hypothesis that the population mean is 40 hours against the alternative that it is higher, we can perform a one-sample t-test.

The null hypothesis (H₀): μ = 40 (population mean is 40 hours)

The alternative hypothesis (H₁): μ > 40 (population mean is higher than 40 hours)

Given a sample of 10 students, the sample mean (x') is 45 hours and the sample standard deviation (s) is 10.5409.

Using the t-test, we calculate the test statistic t:

t = (x' - μ₀) / (s / √n)

Where x' is the sample mean, μ₀ is the null hypothesis population mean (40), s is the sample standard deviation, and n is the sample size (10).

Plugging in the values, we get:

t = (45 - 40) / (10.5409 / √10)

t ≈ 2.38

Next, we determine the critical value or the p-value associated with a significance level of 5%. For a one-tailed test (since we are testing if the mean is higher), the critical value is tc = t(α,n-1), where α is the significance level and n-1 is the degrees of freedom.

At a significance level of 5%, with 9 degrees of freedom (n-1), the critical value is tc = 1.833 (obtained from a t-table or statistical software).

Since the calculated t-value (2.38) is greater than the critical value (1.833), we reject the null hypothesis.

Therefore, at the 5% significance level, we have sufficient evidence to conclude that the population mean is higher than 40 hours based on the given sample data.

Answer:

The rectangle is 3.5 yd x 4 yd

Step-by-step explanation:

Area = length x width = lw

l = length = 2w - 3

w = width

Area = 14(2w - 3)(w) = 14

2w² - 3w - 14 = 0

Use quadratic equation to find the 2 roots of w:  a = 2, b = -3, c = -14

w = 3.5, -2     disregard the negative root

width = 3.5 yd

length = 2(3.5) - 3 = 4 yd

The dimensions of the rectangle are approximately 2.23 yards by 1.46 yards.

We are assuming the width of rectangle to be "x" yards. Then, the length would be (2x - 3) yards, since it is 3 yards less than double the width. The formula for the area of a rectangle is A = l x w, so we can plug in the values we know:

14 = (2x - 3) x x

Expanding the brackets:

14 = 2x² - 3x

Put this equation=0:

2x² - 3x - 14 = 0

Using the quadratic formula:

x = (3 ± √(3² + 4 x 2 x 14)) / (2 x 2)

x = (3 ± √97) / 4

We can ignore the negative root, since the width cannot be negative. Therefore,

x ≈ 2.23

This is the width of the rectangle. To find the length, we can plug this value back into the expression we derived earlier:

length = 2x - 3

length ≈ 1.46

Therefore, the dimensions of the rectangle are approximately 2.23 yards by 1.46 yards

a0 is the regression term that describes the constant or intercept in the linear regression equation.

In a simple linear regression model, the equation takes the form of y = a0 + a1x + e1, where y is the dependent variable (or response variable), x is the independent variable (or predictor variable), a0 is the intercept or constant term, a1 is the coefficient of the independent variable, and e1 is the error term.

The intercept term, a0, represents the value of the dependent variable when the independent variable is zero. For example, in a linear regression model that predicts salary based on years of experience, the intercept would represent the starting salary for someone with zero years of experience. The intercept is an important component of the regression equation because it allows us to make predictions for values of x that are outside the range of our observed data.

The coefficient, a1, represents the change in the dependent variable for each one-unit increase in the independent variable. In the salary example, the coefficient would represent the average increase in salary for each additional year of experience.

Both the intercept and coefficient are estimated from the data using methods such as least squares regression. Once these values are estimated, we can use them to make predictions for new values of x.

In the given triangle x will be 24.2 units.

What is a triangle's definition?

A triangle is a closed 2-D geometric figure with three straight sides and angles. It is formed by connecting three non-collinear points in a plane with straight lines. The three points are called the vertices of the triangle, and the line segments that connect them are called the sides. The angles formed by the sides of the triangle are called the interior angles of the triangle. The addition of the interior angles of a triangle = 180 °. Triangles can be classified based on the lengths of their sides and the measures of their angles, giving rise to different types of triangles such as equilateral, isosceles, scalene, acute, obtuse, and right triangles.

Now,

As given triangles are similar

then their ratio of sides should be same

i.e. x/11=22/10

x=22*11/10

x=121/5

x=24.2

Hence,

             In the given triangle x will be 24.2 units.

Step-by-step explanation:

Given

Minimum, Median, Maximum, Q3 and Q1

See attachment for complete question

Required

Order from least to greatest

In a dataset, the range is:

\(Range = Maximum - Minimum\)

This implies that, the minimum is the least and the maximum is the highest of the dataset

So, we have:

Minimum <         <              <           < Maximum

The median is the middle item; So, the above becomes

Minimum <         < Median <           < Maximum

In a dataset, the IQR is:

\(IQR = Q_3 - Q_1\)

This implies that:

\(Q_3 > Q_1\)

So, we have:

Minimum < Q1 < Median < Q3< Maximum

To determine the number of hours it took to service your mower when the charge was $90, we need to subtract the fixed service call fee ($50) from the total charge and then divide the remaining amount by the hourly rate of $80.

Let's denote the number of hours it took to service the mower as 'h'. The total charge for the service is given as $90.

To find the number of hours, we first subtract the fixed service call fee of $50 from the total charge: $90 - $50 = $40.

Next, we divide the remaining amount ($40) by the hourly rate of $80: $40 / $80 = 0.5 hours.

Therefore, it took 0.5 hours (or 30 minutes) to service your mower when the charge was $90.

The probability of contracting an illness is 0.0475.

According to our question-

D: The patient has the illness

ND: the individual without the disease

TD: The results of the test show the patient has the illness.

P(D) will therefore equal 0.001 since only 0.001 of the population is affected by the disease.

P(ND) = 0.991

Because the test successfully identifies a patient with the condition 99% of the time, P(TD/D) = 0.99.

P(TD/ND) = 0.02 because the test indicates that a healthy person contracts the disease 2% of the time.

We are seeking for P(D|TD) and P(ND|TD), respectively.

According to the Bayes formula, 0.00099/0.00099+0.01982 = 0.00099/0.02081 = 0.0475 = (0.99*0.001)/(0.99*0.001)+(0.02*0.991)

And, \s = 1 - \s = 1 - 0.0475 \s = 0.9525

Therefore,

The likelihood of having an illness is 0.0475.

The likelihood of not having any sick people is 0.9525.

Hence, The probability of contracting an illness is 0.0475.
