Step-by-step explanation:

$2345.20

The total cost price of the car is $2,345.2.

Given that, a car insurance company paid 1758.90 to repair a car that has been rear-ended. This was 75% of the total cost of the repair.

We need to find what was the total cost price of the car.

The amount paid to purchase an article or the price at which an article is made is known as its cost price. The cost price is abbreviated as C.P. Selling Price: The price at which an article is sold is known as its selling price. The selling price is abbreviated as S.P.

Let the total cost price be x.

Now, 75% of x=1758.90

⇒0.75×x=1758.90

⇒x=$2,345.2

Therefore, the total cost price of the car is $2,345.2.

Answer:

163/500 = 0.326

Step-by-step Explanation:

Drawing a Venn diagram for this, we will have 3 circles.  One will represent rock, one will represent country, and one will represent jazz.

There are 11 students that like all 3 types of music.  This means the number 11 goes in the intersection of all 3 circles.

There are a total of 30 students that like rock and country; taking out the 11 that like all 3, this leaves 30-11 = 19 students in the intersection of just rock and country.

There are a total of 27 students that like rock and jazz; taking out the 11 that like all 3, this leaves 27-11 = 16 students in the intersection of just rock and jazz.

There are a total of 22 students that like country and jazz; taking out the 11 that like all 3, this leaves 22-11 = 11 students in the intersection of just country and jazz.

There are 206 students that like rock; taking out the 11 that like all 3, the 19 that like rock and country, and the 16 that like rock and jazz, we have

206-(11+19+16) = 206-(46) = 160 in just rock.

There are 161 students that like country; taking out the 11 that like all 3, the 19 that like rock and country, and the 11 that like country and jazz, we have

161-(11+19+11) = 161-(41) = 120 in just country.

There are 118 students that like jazz; taking out the 11 that like all 3, the 16 that like rock and jazz, and the 11 that like country and jazz, we have

118-(11+16+11) = 118-38 = 80 in just jazz.

This leaves

500-(80+120+160+11+11+19+16) = 500-417 = 83 students that like none of the 3 types of music.

This means for the probability that a student likes neither rock nor country, they either like just jazz or none of the 3; this is (83+80)/500 = 163/500 = 0.326.

The probability that a randomly selected student likes neither rock nor country is;

P(R' ∩ C') = 0.326

Let us denote them as follows;

Number that like rock music be R

Number that like Country music be C

Number that like Jazz music be J

Thus, as we are given we have;

R = 206

C = 161

J = 118

R ∩ C = 30 - 11 = 19

R ∩ J = 27 - 11 = 16

C ∩ J = 22 - 11 = 11

R ∩ C ∩ J = 11

n(only jazz) = J - [(R ∩ J) + (C ∩ J) + (R ∩ C ∩ J)]

n(only jazz) = 118 - (16 + 11 + 11)

n(only J) = 80

n(only Rock) = R - [(R ∩ C) + (R ∩ J) + (R ∩ C ∩ J)]

n(only Rock) = 206 - (19 + 16 + 11)

n(only R) = 160

n(only country) = C - [(R ∩ C) + (C ∩ J) + (R ∩ C ∩ J)]

n(only country) = 161 - (19 + 11 + 11)

n(only C) = 120

Now, the number of students that like neither of the 3 music is;

A' ∩ B' ∩ C' =  500 - [(R ∩ C) + (R ∩ J) +  (C ∩ J) + (R ∩ C ∩ J) + n(only J) + n(only R) + n(only C)]

⇒ 500 - (80 + 120 + 160 + 19 + 16 + 11 + 11)

⇒ A' ∩ B' ∩ C' = 83

Thus, number of students that likes neither rock nor country is;

n(A' ∩ B') = (A' ∩ B' ∩ C') + n(only C)

n(A' ∩ B') = 83 + 80

n(A' ∩ B') = 163

Thus, probability that a randomly selected student likes neither rock nor country = 163/500 = 0.326

Answer:

The answer is divergent ⇒ answer (b)

Step-by-step explanation:

* The series is -5 + 25 + -125 + ........

- It is a geometric series with:

- first term a = -5 and common ratio r = 25/-5 = -5

* The difference between the convergent and divergent

  in the geometric series is :

- If the geometric series is given by  sum  = a + a r + a r² + a r³ + ...

* Where a is the first term and r is the common ratio

* If |r| < 1 then the following geometric series converges to a / (1 - r).  

- Where a/1 - r is the sum to infinity

* The proof is:

∵ S = a(1 - r^n)/(1 - r) ⇒ when IrI < 1 and n very large number

∴ r^n approach to zero

∴ S = a(1 - 0)/(1 - r) = a/(1 - r)

∴ S∞ = a/1 - r

* If |r| ≥ 1 then the above geometric series diverges

∵ r = -5

∴ IrI = 5

∴ IrI > 1

∴ The series is divergent

Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.

In this problem, we have the following System of Three Equations in Three Variables, so our goal is to determine whether [tex]x=10, \ y=-3, \ z=14[/tex] is the solution to this system, that is, the ordered triple [tex]P(x,y,z)[/tex] where three planes intersect.

The easier way to find the answer is to plug in the x, y and z values in the equations and figure out whether the equations satisfy the solutions. Then:

[tex]First \ Equation: \\ \\ 3(10)+7(-3)-14=-5 \\ \\ It \ satisfies \ the \ first \ equation \\ \\ \\ Second \ Equation: \\ \\ 9(10)-(-3)-4(14)=37 \neq 17 \\ \\ It \ doesn't \ satisfy \ the \ second \ equation[/tex]

STOP HERE! Since the x, y an z values doesn't satisfy the second equation, the [tex]x=10, \ y=-3, \ z=14[/tex] is not the solution to the system of equations.

As given,

Number of sheets of paper put in the binder 8 days ago = 50 sheets

Current number of sheets left after 8 days = 2 sheets

So, number of sheets used in 8 days = [tex]50-2=48[/tex] sheets

As it is stated that the same number of sheets are used each day, so number of sheets used per day = [tex]\frac{48}{8}=6[/tex] sheets.

Hence, 6 sheets of paper were used each day.

Answer:

The length is [tex]8\frac{1}{4}\ ft[/tex]

Step-by-step explanation:

we know that

The area of a rectangle is equal to

[tex]A=LW[/tex]

In this problem we have

[tex]A=53\frac{5}{8}\ ft^{2}[/tex]

[tex]W=6\frac{1}{2}\ ft[/tex]

convert to an improper fraction

[tex]A=53\frac{5}{8}=\frac{53*8+5}{8}=\frac{429}{8}\ ft^{2}[/tex]

[tex]W=6\frac{1}{2}=\frac{6*2+1}{2}=\frac{13}{2}\ ft[/tex]

substitute in the formula and solve for L

[tex]\frac{429}{8}=L\frac{13}{2}[/tex]

[tex]L=\frac{429*2}{8*13}=\frac{858}{104}\ ft[/tex]

Convert to mixed number

[tex]L=\frac{858}{104}=\frac{832}{104}+\frac{26}{104}=8\frac{1}{4}\ ft[/tex]

The length of the bathroom floor in this case is 8 1/4 feet.

The area of a rectangle is calculated by multiplying its length by its width. In this case, with the bathroom floor having an area of 53 5/8 square feet and a width of 6 1/2 feet, we can find the length as follows:

Area = Length x Width

53 5/8 = Length x 6 1/2

Length = 53 5/8 / 6 1/2

Length = 8 1/4 feet

Therefore, the length of the bathroom floor is 8 1/4 feet.

The answer would be -21/4

Here’s how you solve it!

First move the variable to the left side which makes it change the sign to a negative

-4y➕1=22

Then you move the constant to the other side and change the sign

-4y=22-1

Now you subtract

22-1=21

-4y=21

Then divide both sides by -4

Then you are left with your answer

Y=-21/4

Answer:

54 square meters

Step-by-step explanation:

Similar figures have corresponding lengths as equal ratios.

Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is [tex]12k=18\\k=\frac{18}{12}\\k=1.5[/tex]

this means the lengths of larger is 1.5 times lengths of smaller.

In terms of area, the scale factor is squared. Hence the scale factor for area is  [tex]k^2=(1.5)^2=2.25[/tex]

this means the area of larger is 2.25 times the area of smaller.

Now, Let area of smaller trapezoid be x so we can say:  [tex]x(2.25)=121\\x=\frac{121}{2.25}\\x=53.78[/tex]

to nearest square meter, x = 54 meters squared

where [tex](AB)_{1,1}[/tex] denotes the element of [tex]AB[/tex] in row 1, column 1, [tex]A_{1,c}[/tex] denotes the first row of [tex]A[/tex], and [tex]B_{r,1}[/tex] denotes the first column of [tex]B[/tex].

It's not A because

[tex](AB)_{1,2}=A_{1,c}B_{r,2}=\begin{bmatrix}-4&-3&5\end{bmatrix}\begin{bmatrix}-4\\-5\\-3\end{bmatrix}=16[/tex]

It's not D because

[tex](AB)_{2,2}=A_{2,c}B_{r,2}=\begin{bmatrix}-5&-4&-2\end{bmatrix}\begin{bmatrix}-4\\-5\\-3\end{bmatrix}=46[/tex]

Answer: first option.

Step-by-step explanation:

Find the common difference d of the arithmetic sequence:

[tex]d=a_n-a_{(n-1)}\\d=989-997\\d=-8[/tex]

Then the formula for the 101st term is the shown below:

[tex]a_n=a_1+(n-1)d[/tex]

Where:

[tex]a_1=997\\d=-8\\n=101[/tex]

Substitute values into the formula. Therefore, you obtain:

[tex]a_n=997+(101-1)(-8)=197[/tex]

Answer:

[tex]a_{101}=197[/tex]

Step-by-step explanation:

The first term of the sequence is

[tex]a_1=997[/tex]

The given sequence  is 997, 989, 981, ...

The common difference is

[tex]d=989-997=-8[/tex]

The nth ter of the sequence is

[tex]a_n=a_1+d(n-1)[/tex]

We plug in the first term and the common ratio to obtain;

[tex]a_n=997-8(n-1)[/tex]

[tex]a_n=997-8n+8[/tex]

[tex]a_n=1005-8n[/tex]

We substitute n=101 to get;

[tex]a_{101}=1005-8(101)[/tex]

[tex]a_{101}=197[/tex]
