What is the area of the polygon?

Answer:

[tex]43.96 \text{ in}[/tex]

Step-by-step explanation:

The equation for circumference is:

[tex]C=2\pi r[/tex]

Using the diagram, we can conclude that the radius of the object is 7 in.

We can substitute this value in for the equation (Note that I will use 3.14 for π):

[tex]C=2\pi r\\C=2*3.14*7\\C=14*3.14\\C=43.96\text{ in}[/tex]

The total money that student saves after paying tax and other expenses is $9600

It is given that

Total earning = $15000

Tax = 1%

Spendings on living expenses = 25%

The percentage is the value per hundred.

Total saving = Total earning- Tax-spendings on living expenses

Total saving  = 15000-(11% of 15000 -(25%of 15000)

Total saving = 15000-11*15000/100 - 15000*25/100

Total saviing  = 15000-1650-3750

Total saving = $9600

Therefore, The total money that student saves after paying tax and other expenses is $9600.

Answer:

∠ B  = 76°

Step-by-step explanation:

The 3 angles in a triangle sum to 180°

sum the 3 angles and equate to 180°

48° + ∠ B + 56° = 180° , that is

∠ B + 104° = 180° ( subtract 104° from both sides )

∠ B = 76°

The correct  null and the alternative hypotheses are:

[tex]h_0: \mu = 2.7\\\\ h_a: \mu < 2.7[/tex]

A hypothesis is an untested statement in mathematics that is supported by all available data and numerous weaker results.

A "conjecture" is a mathematical statement that has not been proven.

The given data in the problem is;

n is the sample size = 40

μ is the population mean = 2.7

[tex]\rm \sigma[/tex] is the standard deviation= 0.2

[tex]\bar x[/tex] is the sample mean:= 2.3

It is found that the null hypothesis always shows the equality sign.

So for the null hypothesis;

[tex]h_0: \mu = 2.7[/tex]

It is observed that the sample mean is less than the population mean in that case, the alternate hypothesis will be;

[tex]h_a: \mu < 2.7[/tex]

Hence the correct  null and the alternative hypotheses are:

[tex]h_0: \mu = 2.7\\\\ h_a: \mu < 2.7[/tex]

Using sampling concepts, it is found that the best way to perform a randomized experiment with the goal of determining if this new hamburger will sell better than the hamburger that is currently sold is as follows:

Randomly select 40 restaurants, let each one decide if it wants to sell the new hamburger, and compare sales in those restaurants to sales in the restaurants that chose not to sell the new hamburger.

It is is a common statistics practice, when we want to study something from a population, we find a sample of this population.

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

In this problem, a sample of randomly selected restaurants should be taken to sell the new hamburger, and then be compared with the ones who sell the old hamburger to see if sales increased, hence the correct option is:

Randomly select 40 restaurants, let each one decide if it wants to sell the new hamburger, and compare sales in those restaurants to sales in the restaurants that chose not to sell the new hamburger.

Answer: 69.3 and 110.7 degrees

Step-by-step explanation:

Answer:

1. -3/6 is negative, because it descends by 3 and goes over by 6.

2. My first answer literally gives the keyword negative, therefore it's a negative line because it has a negative slope.

1. -8/0 is undefined, because there is a rise but there is no run, which also means that it's a:

2. vertical line

1. -5/-10 simplifies to 5/10 or 1/2, which is positive because it rises by 5(or 1) and runs over by 10(or 2).

2. Thus, this means that it's a positive line since it has a positive slope.

1. 0/-2 is zero, because when you actually solve the equation it'll equal 0.

2. This means that it'll have a horizontal line since there is no rise but there is a run only.

The age of the plant if the height of the plant is 19 inches is 28 months.

The general equation for logarithmic regression is given by the formula,

y = a+b ln(x)

where y is the dependent variable, x is the independent variable, and a and b are the constants.

Let y be the height of the plant and x be the age of the plant.

If we plug in any two of the points in the equation, to get the value of a and b.

        [tex]18=a+b\rm \ ln(1)\\\\18=a+0\\\\a = 18[/tex]

        [tex]18.21=18+b\rm \ ln(2)\\\\0.21=b\ ln(2)\\\\b = 0.3[/tex]

Thus, the logarithmic expression represents the relationship between the age of the plant and the height of the plants is y=18+0.3 ln(x).

Now, if the height of the plant is 19, inches than the age of the plant is,

[tex]y=18+0.3\rm\ ln(x)\\\\19 =18+0.3 ln(x)\\\\x = 28.03\approx 28[/tex]

hence, the age of the plant if the height of the plant is 19 inches is 28 months.

The null hypothesis, [tex]\rm H_{0}[/tex]  for  the given situation in the question, will be  

[tex]\rm H_{0}:\mu\leq 10[/tex]

For finding the null hypotheses  we will follow the data given in the  question  

The null hypothesis,  [tex]\rm H_{0}[/tex]  is the hypothesis of no difference and as such, it always has an equality sign;

=, ≤, ≥

In order to identify the null we lookout for specific keywords that will provide us with information on the type of inequality sign.

In this situation, the coach claims that the average number of fouls committed per game is no more than 10.

Since µ represents the team's average number of fouls per game, this statement can be written in mathematical symbols as;

[tex]\mu\leq 10[/tex]

That is [tex]\mu[/tex] is less than 10 and the average number of fouls committed per game is less than 10.

This statement will be our null hypothesis since it contains an equality sign.

[tex]\rm H_{0}:\mu\leq 10[/tex]

Thus null hypothesis, [tex]\rm H_{0}[/tex]  for  the given situation in the question, will be  

[tex]\rm H_{0}:\mu\leq 10[/tex]

Answer:

[tex]f(x) = 10*(b)^x[/tex]

Step-by-step explanation:

exponential function : [tex]y=a*(b)^x[/tex]

where a = y intercept and b = factor ( what you multiply by )

looking at the table the y intercept is at (0,10) so a = 10

so we now have y = 10 * (b)^x

to find the factor we simply plug in one of the ordered pairs.

note that the ordered pair chosen does not effect the outcome

i chose (2,250)

we have y = 10 * (b)^x

(x,y) = (2,250)

250 = 10 * (b)^2

divide both sides by 10

25 = b^2

take the square root of both sides

5 = b

the final equation would be f(x) = 10 * (b)^x
