The table shows different flood types and their frequencies.

Total frequency of all flood types = 18 + 6 + 4 + 2 = 30

frequency of river flood = 6

Recall, probability is expressed as

number of favorable outcomes/number of total outcomes

Thus, the estimated probability that a flood in 2021 in that state will be a river flood is

6/30 = 0.2

By changing 0.2 to percentage, we have

0.2 x 100 = 20%

The correct option is C. 20%

Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour then Karen working alone will paint a house in 3 hours.

Since Betty takes 6 hours to paint a house alone, that indicates she can paint 1/6 of the house in 1 hour.

Karen can even paint 1/x in 1 hour

Both of them will paint the house in 3/2 hours.

We then add them together which gives:

1/6 + 1/x = 3/2x

The lowest common multiple is 6x

1x/6x + 6/6x = 9/6x

We then leave out the denominators

1x + 6 = 9

simplifying the above equation, we get

x = 9 - 6

x = 3

Therefore, the value of x = 3.

Karen working alone will paint a house in 3 hours.

The complete question is:

Betty and Karen have been hired to paint the houses in a new development. Working together, the women can paint a house in two-thirds the time that it takes Karen working alone. Betty takes 14 h to paint a house alone. Betty takes 6 h to paint a house alone.

The value of question are 65+[tex]\underline{115}[/tex]=180, [tex]11x+\underline{48}=180^o[/tex], [tex]11x=\underline{132}[/tex] and [tex]x=\underline{12}[/tex].

In the given question we have to find the value of missing term.

(1) 65+......=180

(2) 11x+.......=180

(3) 11x=.........

(4) x=........

To solve this question we have to use some theorem.

Firstly solving the first question.

As we know that the angle of straight line is 180[tex]^o.[/tex]

So from the diagram

[tex]65+z=180^o[/tex]

Subtract 65 on both side

[tex]65+z-65=180^o-65[/tex]

[tex]z=115[/tex]

Hence, 65+[tex]\underline{115}[/tex]=180.

Now finding the value of second question.

Using Alternate Exterior Angles Theorem

According to theorem the angle beside 11x - 17 is 65.

As we know that the angle of straight line is 180[tex]^o.[/tex]

So  11x-17+65=180[tex]^o.[/tex]

Simplifying

So [tex]11x+\underline{48}=180^o[/tex]

Now finding the value of third question.

From the second question answer we get [tex]11x+{48}=180^o[/tex]

Now solving this equation to find the value of 11x

Subtract 48 on both side

[tex]11x+{48}-48=180^o-48[/tex]

[tex]11x=132[/tex]

Hence, [tex]11x=\underline{132}[/tex]

Now solving the fourth question.

To find the value of fourth question we further simplify the answer of third question.

[tex]11x=132[/tex]

Divide by 11 on both side

[tex]\frac{11}{11}x=\frac{132}{11}[/tex]

[tex]x=12[/tex]

Hence, [tex]x=\underline{12}[/tex]

The ratio term of given geometric progression is 3 and the 9th term of the GP is 6561.

What is Geometric Progression?

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio. For instance, the geometric progression 2, 6, 18, 54,_ _ _ _ has a common ratio of 3.

Given in question,

first term of the GP is 1,

4th term of the GP is 27,

[tex]4^{th} term = ar^3[/tex]

[tex]ar^3 = 27[/tex]

Therefore, the ratio term of geometric progression, r = 3

We know that, [tex]a_n = ar^{n-1}[/tex]

[tex]a_9 = ar^8[/tex]

[tex]a_9 = 3^8[/tex]

The slope intercept form of equation of the line is  y = 4x - 2

The slope intercept form of equation of the line that includes the point (3,10) has a slope of 4. is  y = 4x - 2

This is an equation of the form y = mx + c, where:

the coefficient of x is the slope

c is the intercept

To calculate the equation of the line that include point  (3,10) has a slope of 4 we solve as follows

( y - y' ) / ( x - x' ) = 4

( y - y' )  = ( x - x' ) = 4

where y' = 10, and x' = 3

y - 10 = (x - 3 ) * 4

y - 10 = 4x - 12

y = 4x - 12 + 10

y = 4x - 2

The slope intercept form of equation of the line is  y = 4x - 2

Answer:

The answer is C

Step-by-step explanation:

If you substitute every x value for 5, you know that every equation can have 5 as an answer but C.

A. 3x+2=4x-3

Isolate the x(s) and combine like terms

3x+2-2=4x-3-2

3x=4x-5

3x-4x=4x-4x-5

-x=-5

-x(-1)=-5(-1)

x=5

Therefore A is a solution

B. (x+2)(x-5)=0

Substitution--Substitute every x for a 5

(7)(0)=0

anything multiplied by 0 will be 0

B. Is a solution because it is true.

C. 4x+2=15

Isolating the x(s) and combine like terms

4x+2-2=15-2

4x=13

4x÷4=13÷4

x=3.25

C is not a solution because x should equal to 5 but in this equation x can only be equal to 3.25. C is wrong.

We know our answer so we don't have to keep solving the rest of the equations.

But I'll just do D

D. 3x-10=x

Isolate the x(s) and combine like terms

3x-x-10=x-x

2x-10=0

2x=10

2x÷2=10÷2

x=5

D is a solution.

Answer:

x = 1

Step-by-step explanation:

Horizontal asymptotes are the y-values for which a particular function is undefined;

Finding the horizontal asymptote for linear reciprocal function is quite simple;

For this kind of function, where there is no x term in the numerator, the horizontal asymptote is just equivalent to the constant added to the fraction (note: having no added constant is the same as having an added 0);

so:

f(x) = 1/(x - 1) = (1/( - 1 )) + 0

The horizontal asymptote is y = 0 for this function.

If it was F(x) = (1/(x - 1)) + 1, the horizontal asymptote would be  y = 1

= [tex]4\sqrt{x+2} - 6[/tex]

Answer:

Step-by-step explanation:

Given functions:

[tex]\begin{cases}f(x)=4x-6\\g(x)=\sqrt{x+2}\end{cases}[/tex]

(f o g)(x) is a composite function.  

Composite functions are when the output of one function is used as the input of another.

Therefore, the given composite function (f o g)(7) means to substitute the function g(x) when x=7 in place of the x in function f(x).

[tex]\begin{aligned}\implies (f \circ g)(7)&=f[g(7)]\\& = f(\sqrt{7+2})\\&=f(\sqrt{9})\\&=f(3)\\&=4(3)-6\\&=12-6\\&=6\end{aligned}[/tex]
