Find the area of the regular polygon. Round your answer to the nearest hundredth.
(4 , 3.3)
The area is about __
square units.

Answer:

25%

Step-by-step explanation:

Sum the parts of the ratio, 7 + 5 + 4 = 16 parts

Of the 16 parts, 4 parts are blue, thus percentage is

[tex]\frac{4}{16}[/tex] × 100% = [tex]\frac{1}{4}[/tex] × 100% = 25%

The expression ㏑(4/9) is equivalent to the expression will be 2 ㏑ 2 - 2 ㏑ 3. Then the correct option is A.

The equivalent is the expression that is in different forms but is equal to the same value.

Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.

The expression is given below.

⇒ ㏑(4/9)

Simplify the equation, then we have

⇒ ㏑(4/9)

⇒ ㏑ 4 - ㏑ 9

⇒ ㏑ (2)² - ㏑ (3)²

⇒ 2 ㏑ 2 - 2 ㏑ 3

The expression ㏑(4/9) is equivalent to the expression will be 2 ㏑ 2 - 2 ㏑ 3. Then the correct option is A.

Answer:

-7

Step-by-step explanation:

y−x=9 ⇒ y=x+9

10+2x=−2y

5+x= -y  ====== replacing y with x+9

5+x= -x-9

2x= -14

x= -7

Answer:

-7

Step-by-step explanation:

y - x = 9

10 + 2x = -2y

Solve for y in the first equation.

y = 9 + x

Put y as 9 + x in the second equation and solve for x.

10 + 2x = -2(9 + x)

10 + 2x = -18 - 2x

2x + 2x = -18 - 10

4x = -28

x = -28/4

x = -7

Answer:

The probability that there are 2 or more fraudulent online retail orders in the sample is 0.483.

Step-by-step explanation:

We can model this with a binomial random variable, with sample size n=20 and probability of success p=0.08.

The probability of k online retail orders that turn out to be fraudulent in the sample is:

[tex]P(x=k)=\dbinom{n}{k}p^k(1-p)^{n-k}=\dbinom{20}{k}\cdot0.08^k\cdot0.92^{20-k}[/tex]

We have to calculate the probability that 2 or more online retail orders that turn out to be fraudulent. This can be calculated as:

[tex]P(x\geq2)=1-[P(x=0)+P(x=1)]\\\\\\P(x=0)=\dbinom{20}{0}\cdot0.08^{0}\cdot0.92^{20}=1\cdot1\cdot0.189=0.189\\\\\\P(x=1)=\dbinom{20}{1}\cdot0.08^{1}\cdot0.92^{19}=20\cdot0.08\cdot0.205=0.328\\\\\\\\P(x\geq2)=1-[0.189+0.328]\\\\P(x\geq2)=1-0.517=0.483[/tex]

The probability that there are 2 or more fraudulent online retail orders in the sample is 0.483.

The value of the 2nd 5 is 50,000 and it is in the ten thousands place

Answer:

The percentage points within which the obtained results would differ from the real population value.

Step-by-step explanation:

The ideas of the margin of error and confidence interval are borne from the observed truth, which is that there is always room for error in any statistically computed figure such as a survey or poll. For example, the result of a poll could show an 80% confidnce interval with a margin of error of 3%. This simply means that if the poll was repeated, 80% of the real population would fall within an estimate of 3%.

Statistics are not always error proof. Sometimes, the results might even be totally different from the computed results. So, it is very important that room is made for the possibility of an error, and that is why we need the mrgin of error.

Answer:

19.2

Step-by-step explanation:

Net income                                   $940,000

No of shares outstanding             $188,000

Earning per share = Net income / no of shares outstanding  

Earning per share = 940,000 / 188,000

Earning per share = 5

Market price per share  = 96

Price earning ratio = Market price / Earning per share

Price earning ratio = 96 / 5  

Price earning ratio = 19.2

Answer:

1,498,454,000 sq. miles

Step-by-step explanation:

Volume of a sphere = 4/3 (3.14) r^3

So since the diameter is 1420 miles, the radius would be half.

V = 4/3 x (3.14) x 710^3

V=4.18666667 x 357,911,000

V = 1,498,454,054.5 but if you want it rounded to the nearest thousand then it'd be 1,498,454,000.

Answer:

1. All real numbers

2. All real numbers except y = 0

3. All real numbers except x = -7

4. All real numbers except b = 10

Step-by-step explanation:

For any function to be defined at a particular value, it should not be approaching to a value [tex]\infty[/tex] or it should not give us the [tex]\frac{0}{0}[/tex] (zero by zero) form when the input is given to the function.

The value of function will depend on the denominator.

Now, let us consider the given functions one by one:

1. 5y+2

Here denominator is 1. So, it can not attain a value [tex]\infty[/tex] or [tex]\frac{0}{0}[/tex] (zero by zero) form

So, for all real numbers, the function is defined.

[tex]2.\ \dfrac{18}{y}[/tex]

At y = 0, the value

[tex]At\ y =0, \dfrac{18}{y} \rightarrow \infty[/tex]

So, the given function is defined for all real numbers except y = 0

[tex]3.\ \dfrac{1}{x+7}[/tex]

Let us consider denominator:

x + 7 can be zero at a value x = -7

[tex]At\ x =-7, \dfrac{1}{x+7} \rightarrow \infty[/tex]

So, the given function is defined for all real numbers except x = -7

[tex]4.\ \dfrac{2b}{10-b}[/tex]

Let us consider denominator:

10-b can be zero at a value b = 10

[tex]At\ b =10, \dfrac{2b}{10-b} \rightarrow \infty[/tex]

So, the given function is defined for all real numbers except b = 10

Venn diagram are used to represent the relationships between sets. The correct notation for the shaded region is (d) F.

Given the attached Venn diagram.

The shaded region highlights

This means that options (a) and (b) are false because set G is not shaded

This also means that option (c) is false because the shaded region is just a part of set M, and not the whole set M.

Hence, we can conclude that option (d) is correct because the whole of set F is shaded.

Answer:

[tex] \frac{c}{a + b} [/tex]

Step-by-step explanation:

Point A is on the origin, hence its coordinates would be (0, 0). Coordinates of point C are (a + b, c)

Slope of AC

Answer:

In the green box of the numerator, enter "c"

In the gray bax in the denominator, there should be "a"

Answer:

41.1 units²

Step-by-step explanation:

The given figure is composed of a semicircle and a triangle.

The diameter of the circle = the base of the triangle = the distance between point D and point F on the x-axis.

Therefore,

Diameter (d) of circle = 8 units

Radius of circle = [tex] \frac{diameter}{2} = \frac{8}{2} [/tex]

[tex] radius (r) = 2 [/tex]

Base of triangle = 8 units

The height of the triangle = the perpendicular distance between point E and segment DF on the y-axis

Height of triangle = 4 units

=>Area of the figure = area of triangle + area of semicircle

Area of figure = [tex] \frac{1}{2}bh + \frac{1}{2}*pie*r^2[/tex]

[tex] = \frac{1}{2}*8*4 + \frac{1}{2}*3.14*4^2[/tex]

[tex] = \frac{1}{2}*32 + \frac{1}{2}*50.24[/tex]

[tex] = 16 + 25.12 [/tex]

[tex] = 41.12 [/tex]

Area of the figure = 41.1 units² (to the nearest tenth)

Answer:

The amount in the account at the end of three years will be $59,861.

Step-by-step explanation:

The formula to compute the amount at the end of t years, compounded continuously is:

[tex]A=P\times e^{t\times i}[/tex]

Here,

A = Amount at the end

P = Principal amount

i = interest rate

t = number of years.

It is provided that:

P = $50,000

i = 6%

t = 3 years

Compute the amount in the account at the end of three years as follows:

Number of 7-digit PIN codes using only the digits 0-9 are possible is 9000000.

We need to find the how many different 7-digit PIN codes using only the digits 0-9 are possible.

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.

First digit: 1,2,3,4,5,6,7,8,9 (cannot be 0 else it will be a 6-digit number) (9 choices)

2nd digit: 0,1,2,3,4,5,6,7,8,9 (10 choices)

As we go on, we realise that from the 2nd to 7th digit, we have 10 options (0,1,2,3,4,5,6,7,8,9)

Number of ways to get 7-digit numbers using 0-9 would be 9×10×10×10×10×10×10=9000000.

Therefore, number of 7-digit PIN codes using only the digits 0-9 are possible is 9000000.

Step-by-step explanation:

This should be researched with a hypothesis test on the proportion of tourists visiting Rock City.

The claim that want to be tested is if the proportion has increased from the past proportion (π=0.75).

Then, the alternative hypothesis will state that the proportion is significantly higher than 0.75.

On the contrary, the alternative hypothesis will state that the proportion is not significantly different than 0.75.
