The probability that you will catch a t-shirt that is not of medium size would be 0.7

What is the probability?

Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty.

Small=S=20, M=medium=30,

L = Either large or extra large=50

P(T-shirt that is not a medium)= 1 - P(T-shirt is medium)

                                           = 1 - 30/100

                                           = 1 - 0.3

                                           = 0.7

Hence, the probability that you will catch a t-shirt that is not of medium size would be 0.7

The values of the functions defined in the piecewise function are f(0) = 5 and f(-4) = 11

From the question, we have the following piecewise function that can be used in our computation:

f(x) = | x + 5                 x < -2

         x² + 2x + 3        x ≥ -2

Evaluating the function f(0)

In this function, we have the x value to be

x = 0

This x value is at the domain x < -2

So, we make use of

f(x) = x + 5

Substitute 0 for x in f(x) = x + 5

f(0) = 0 + 5

Evaluate

f(0) = 5

Evaluating the function f(-4)

In this function, we have the x value to be

x = -4

This x value is at the domain x ≥ -2

So, we make use of

f(x) = x² + 2x + 3

Substitute -4 for x in f(x) = x² + 2x + 3

f(-4) = (-4)² + 2(-4) + 3

Evaluate

f(-4) = 11

Hence, the value of f(-4) is 11

chamber of commerce’s claim at the 0.02 level of significance, z = -1.75

What is z test?

If the data is distributed normally, a z test can be used to determine whether the means of two populations differ from one another. The z test statistic's value must be determined, together with the null hypothesis and alternative hypothesis setups, for this reason. On the z critical value, the decision criterion is based. The distribution graph is divided into acceptance and rejection zones during hypothesis testing by the z critical value. The null hypothesis can be rejected if the test statistic lies inside the rejection region; otherwise, it cannot.

a recent survey reported that small businesses spend 24 hours a week marketing their business.

these businesses are spending less than 24 hours a week on marketing. the chamber conducts a survey of 58 small businesses within their state and finds that the average amount of time spent on marketing is 22.7 hours a week.

assuming that the population standard deviation is 6.1 hours.

Given n = 93, u =24, x' = 23, α=5.5

Step-by-step explanation:

After 10 years the population growth will be 3054, if the population doubles after every 17 years.

A mathematical function with the form f (x) = ae^x is an exponential function. "x" is a variable, and "a" is a constant that serves as the function's base and must be greater than 0. The transcendental number e, or roughly 2.71828, is the base for exponential functions that is most frequently used.

Growth rate = 100% in 17 years

  In 1 year = 5.88% growth

Initial population = P₀ = 1725

Time = 17 years

So, after 10 years population

        P= P₀ ( 1 + [tex]\frac{r}{100}[/tex])^t

           = 1725 ( 1 + 5.88/100 )^10

           =≈ 1725 * 1.77

           =≈ 3054

Hence, the population growth after 10 years at the rate of 5.88 % would be 3054.

The plant's height after 34 months will be 89cm if the plant is already 55 centimeters tall.

Height is defined in mathematics as the vertical distance from the object's top to its base. It is occasionally referred to as 'altitude.' The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.

Height and elevation all refer to the vertical distance between the top and bottom of something or between a base and anything above it. Height refers to something measured vertically, whether it be high or low.

Given, the relation between the height and the months is:

H(m)=55+m

Now, we have to find the height of the plant after 34 months.

So, we substitute m=34 in the expression to obtain height,

H(m)=55+m

H(34)=55+34

H(34)=89cm

Hence the height will be 89cm

Answer:

(-8, -8)

Step-by-step explanation:

You need to solve one of the equation for x or y.  I am going to solve the bottom equation for x

4x -4y = 0  Add 4y to both sides

4x = 4y  Divide both sides by 4

x = y  Substitute y in for x in the first equation

-7x + 4y = 24

-7y + 4y = 24  Combine like terms

-3y = 24  Divide both sides by -3

y = -8

Since x = y

x = -8

Check:

-7y + 4y = 24

-7(-8) + 4(-8) = 24

56 - 32 = 24

4x - 4y = 0

4(-8) - 4(-8) = 0

-32 + 32 = 0

0 = 0

The value of x is 35 and the value of y is 82.

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

Given that the three angles of the triangle are 40, 2x and y-12. The value of x and y will be calculated as,

2x = y-12

2x + y-12 + 40 = 180

2x + y =180-40+12

2x + y = 152

2x - y = -12

___________

4x = 140

Margin of error = Critical value x Standard deviation for the population.

Margin of error = Critical value x Standard error of the sample.

Given, Margin of error (m) = 0.08

          z (at 80% confidence level)=1.282

Sample size(n) = (z/m)^2 p (1-p)

In order to find the sample size, we must know the value of proportion.

The value of proportion is missing so, in the absence of proportion, we will consider it as 0.5.

p = 0.5

∴ Sample size = (z/m)^2 p (1-p)

On Subtracting 1 from your sample size, we get

100 – 1 = 99.

On Subtracting confidence level from 1, and then divide by two.

(1 – .997) / 2 = 0.0015

Now, df = 99 and α = 0.0015

from the table at df = 99 we got 2.262.

Divide your sample standard deviation by the square root of your sample size.

Using line of best fit and correlation coefficient, the correlation coefficient of determination represent the percentage of data that is closest to the lines of best fit.

What is line of best fit?

Line of best fit refers to the "a line through a scatter plot of data points that best expresses relationship between those points". Lines of best fit is used to describe data and predict data where the new data will appear. Examples for lines of best fit is 'Least square method'.

Two variables are said to be correlated or to have a correlation coefficient when "changes in the value of one variable produce changes in the variable of the other variable."

In order to find the correlation between two variables on a graph, the question asks for the line of best fit and correlation coefficient.

Only when there is a linear correlation between the variables—that is, when the relationship between the variables is linear on a graph—does the correlation coefficient hold true.

Variation in "x" on the graph leads to variation in "y." Variation in "y" on the graph results in variation in "x." The variables "x" and "y" are jointly dependent on the graph.

The correlation coefficient between two variables on the graph is calculated in this manner.

Hence, using line of best fit and correlation coefficient, the correlation coefficient of determination represent the percentage of data that is closest to the lines of best fit.
