5. Ruth Fanelli has decided to drop her collision insurance because her cart is getting old. Her total annual premium is $916, of which $170.60 covers collision insurance.

a. What will her annual premium be after she drops the collision insurance?
b. What will her quarterly payments be after she drops the collision coverage?

Answers

Answer 1

Ruth's quarterly payments after she drops collision insurance will be $186.35.

Ruth's annual premium will be $745.40 after she drops the collision insurance.

a. To find Ruth's annual premium after she drops collision insurance, we need to subtract the portion of the premium that covers collision insurance from the total premium:

New annual premium = Total annual premium - Cost of collision insurance

New annual premium = $916 - $170.60

New annual premium = $745.40

Therefore, Ruth's annual premium after she drops collision insurance will be $745.40.

b. To find Ruth's quarterly payments after she drops collision insurance, we need to divide her new annual premium by 4:

Quarterly payment = New annual premium / 4

Quarterly payment = $745.40 / 4

Quarterly payment = $186.35 (rounded to two decimal places)

These are independent events

and probability of drawing red marble is 1/3

and probability of drawing two blue marble is 1/2 ,1/2.

According to the statement

A bag contains 1 white (W), 3 blue (B1, B2, B3), and 2 red (R1, R2) marbles.

And we have to find the probability of tossing a head and drawing a red marble. and probability of drawing two blue marbles if the first marble is not replaced.

here we solve this problem by Probability

So, Probability of drawing red marble = Number of red marble / total number of marbles.

Probability = 2/6

Probability = 1/3.

Then

Probability of drawing blue marbles = number of blue marbles /total marbles

Probability = 3/6

Probability = 1/2.

1st blue marble Probability =1/2

2nd blue marble Probability = 1-(1/2) = 1/2.

These are non dependent events because they do no affect the probability of each others.

So, These are independent events

Answers

The equation p=4+3y is maximised at (4,5) and the maximised value is 31.

Given equation p=4x+3y and constraints x>0,x<4, y<5.

We have to maximise the equation p=4x+3y with constraints x>0,x<4,y<5.

To find out the points we have to make graphs of the constraints first.

From the graph we have found that points are (0,0),(0,5),(4,0),(4,5).

The above points are common points of graphs of all constraints.

The value of equations are as under:

At (0,0) , p=4*0+3*0=0

At (0,5), p=4*0+3*5=15

At (4,0),p=4*4+3*0=16

At (4,5),p=4*4+3*5=16+15=31

Maximum value of p is 31 and that is for (4,5).

The 1997 Red River flood was considered a 200-year flood. Why is it now considered only to be a 65-year flood

Answers

Large floods in 2007 and 2010 changed the flood recurrence curve.

What caused the Red River flood 1997?

A extremely unusual thawing of winter snow and river ice after a winter season that saw far above-normal precipitation across the Northern Plains was the main contributor to the flooding in 1997.

Why is the Red River called the Red River?

After it was explored in 1732–33 by the French voyageur Pierre Gaultier de Varennes et de La Vérendrye, the river, called Red because of the reddish brown silt it carries, served as a transportation link between Lake Winnipeg and the Mississippi River system.

How did the Red River flood affect people?The floodway was designed to manage a flow of 1,700 m3/s, but 1,800 m3/s was instead used. 28,000 people were evacuated due to the 1997 flood, which also caused $500 million in damage. Additionally, parts of Minnesota, North Dakota, and southern Manitoba were inundated by the river.

How many different ways are there to choose a dozen donuts from the 4 varities at a donut shop so that you get atleast one donut of every variety g

Answers

There are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop. (at least one donut of every variety must be selected)

How to calculate the number of ways to select items?

There are 'r' items from 'n' different varieties (repetition allowed). Then, the number of ways to select items is given by

The number of ways =  [tex]_{n+r-1}C_r[/tex]

Where the combination [tex]_{n}C_r[/tex] is calculated as

[tex]_{n}C_r=\frac{n!}{r!(n-r)!}[/tex]

Calculation:

It is given that there are 4 varieties of donuts in a shop. I.e., n = 4

Number of donuts to be selected r = 12 (one dozen)

And also given that at least one donut of every variety has to be selected.

Since there are 4 varieties, at least one from each of these means the count is 4.

So, the remaining number of donuts to be selected is 12 - 4 = 8.

So, r becomes 8 i.e., r = 8

On substituting,

the number of ways of selecting the remaining 8 donuts = [tex]_{4+8-1}C_4[/tex]

⇒ [tex]_{11}C_4[/tex]

⇒ [tex]\frac{11!}{4!(11-4)!}[/tex]

⇒ [tex]\frac{11!}{(4!)(7!)}[/tex]

⇒ 330

Therefore, there are 330 different ways for choosing a dozen donuts from the 4 varieties at a donut shop.

The requried, rounded to four decimal places, cos(A) is approximately -0.9682. The correct answer is option d. -0.9682.

To find cos(A) in quadrant II, we can use the given information and the trigonometric identity  [tex]sin^2(A) + cos^2(A) = 1[/tex].

Given [tex]sin(A) = 1/4[/tex], we can find  [tex]cos(A)[/tex]  as follows:

Find the equation of the line passing through (0, -1) that is perpendicular to the line y=3/5x-3

Answers

Answer: [tex]y=-\frac{5}{3}x-1[/tex]

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals, so the slope of the line we want to find is -5/3.

Since the y-intercept is (0,-1), the equation is [tex]y=-\frac{5}{3}x-1[/tex]

The equation of the line passing through (0, -1) that is perpendicular to the line y=3/5x-3 is 5x + 3y + 3 = 0.

What is standard equation of the line?

A line of the standard form y = mx + c , where m is the slope of the line and c is a y-intercept. Another way to express the equation for a line is in standard form.

Slope: A line's slope provides information on the steepness and direction of the line.

By figuring out the difference between both the coordinates of the two points, (x1,y1) and (x2,y2), it is simple to calculate the slope of such a straight line through them. The letter "m" denote the slope of the line.

Relation between slope of two perpendicular lines are-

Two perpendicular lines' slopes are the negative reciprocals of one another. This indicates that a line's slope is -1 / m if it's perpendicular to the a line with slope m.

Calculation for the equation of the line.

Consider the given equation;

y=3/5x-3 (compare this with the standard equation)

The slope 'm' is 3/5

Use the relation of slopes of two perpendicular line.

The slope of orthogonal line will be -1/m

Slope = -5/3

Put the slope in the slope point equation of line.

(y - y1) = m(x - x1)

where (x1,y1) = (0,-1)

Substitute the coordinates in the equation

y - (-1) = (-5/3)×(x - 0)

y + 1 = -5x/3

Further simplifying the equation,

5x + 3y +3 = 0

Therefore, the equation of the line passing through (0, -1) that is perpendicular to the line y=3/5x-3 is 5x + 3y +3 = 0.

MIDPOINTS

[tex](\frac{x_{1}+x_{2} }2}, \frac{y_{1}+y_{2} }2} )[/tex] = [tex](\frac{4-6}2,\frac{4+2 }2} )[/tex] = (-1, 3)

Next, we will use the distance formula, [tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex].

DISTANCE

[tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex] = [tex]\sqrt{(-1-3)^{2} + (3-2)^{2} }[/tex] = [tex]\sqrt{17}[/tex]

[tex]\sqrt{(x_{1}-x_{2})^{2} + (y_{1}-y_{2})^{2} }[/tex] = [tex]\sqrt{(3+2)^{2} + (2-1)^{2} }[/tex] = [tex]\sqrt{26}[/tex]  

a. To find the coordinates of endpoints we must add two x values and divide by 2 and then add 2 y- values and divide by 2.

(2+4)/2=3  (4+0)/2=2

Coordinates of midpoints are (-1,3), (-2,1), (3,2)

sqrt((-1+2)^2 + (3-1)^2)

Sqrt(5)

Repeat.

Sqrt(17)

Sqrt(26)

The lengths of the inner triangle are as follows:

Answers

Answer:

[tex]254 \frac{12}{17}[/tex] or approximately 254.71

Step-by-step explanation:

First, you need to find out how many gallons it will take to travel 866 miles. Because the car's avg miles/gallon is 13.6, you divide 866 by 13.6. However, this gets you an irrational number. To avoid this, make 13.6 into a fraction. Now divide 866 by [tex]13 \frac{3}{5}[/tex]. This becomes 866 ÷ [tex]\frac{68}{5}[/tex]. Convert this into a multiplication problem by converting [tex]\frac{68}{5}[/tex] into its reciprocal. This gets you 866 × [tex]\frac{5}{68}[/tex]. This gets you [tex]\frac{2165}{34}[/tex]. Now that you have the amount of gallons it will take to get to your destination, multiply it by 4. [tex]\frac{2165}{34}[/tex] × [tex]4[/tex][tex]= \frac{4330}{17}[/tex].

the length of a rectangle exceeds its width by 17 inches, and the area is 18 square inches. what are the length and width of the rectangle

Answers

The length and width of the rectangle are 18 in and 1 in, respectively.

Quadrilaterals

There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid, and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, in a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

The area of a rectangle can be found for the formula : b*h, where b = base and h =height.

For this question, the length exceeds its width by 17 inches - L=W+17. Here, the length is the base and the width is the height. Thus,  from the value of area given, you can find the values of the length and width of the rectangle.

A=b*h

18=(W+17)*W

18=W²+17W

W²+17W-18=0

Solving this quadratic equation, you have:

[tex]w_{1,\:2}=\frac{-17\pm \sqrt{17^2-4\cdot \:1\cdot \left(-18\right)}}{2\cdot \:1}[/tex]

[tex]w_{1,\:2}=\frac{-17\pm \:19}{2\cdot \:1}[/tex]

w1=1 and w2= -18

For dimensions, only positive numbers must be used. Then, the width is equal to 1 inch.

As, the area (l*w) is 18 in², see.

18=l*w

18=l*1

l=18 in

The table displays the scores of students on a recent exam. Find the mean of the scores to the nearest 10th.

Answers

Answer: 75.8

HOPE THIS HELPS!

The mean of the scores to the nearest 10th digit will be 74.9.

What is Mean?

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.

Then the mean is given as,

Mean = (Total score) / (total student)

The total score will be

Total score = 65 x 8 + 70 x 7 + 75 x 3 + 80 x 8 + 85 x 3 + 90 x 2 + 95 x 2

Total score = 520 + 490 + 225 + 640 + 225 + 180 + 190

Total score = 2470

The total number of students will be

Total student = 8 + 7 + 3 + 8 + 3 + 2 + 2

Total student = 33

Then the mean will be

Mean = 2470 / 33

Mean = 74.85 ≈ 74.9
