Answer:

5.7909 * 10^7

Step-by-step explanation:

Scientific notation uses a number from 1 to under 10 and an integer power of 10.

57,909,000 = 5.7909 * 10,000,000 = 5.7909 * 10^7

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%

Answer:

Because when your finding a point on the x line going left goes towards the negative side, like a number line. So for the y line think of it like the number line but going up is positive and going down is negative.

so if we wanted to go right 6 units and down 3 units it would written as:

(x+6,y-3) Because going right on the x line is like adding 6 units and going down on the y line is like subtracting 3 units for this example

Answer:

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Step-by-step explanation:

Area of a Circle

A circle of radius r has an area calculated by the following formula:

[tex]A=\pi r^2[/tex]

The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.

A given circle has a diameter of 5 inches.

The radius of this circle is r = 5/2 = 2.5 inches.

Thus, the area is calculated below:

[tex]A=\pi 2.5^2 = 6.25\pi[/tex]

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Answer:

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Step-by-step explanation:

Given

Total length of one roll of ribbon = 9 feet

As the pieces have to be cut into inches, we will convert the measurement in feet to inches

As there are 12 inches in one feet, 9 feet will be equal to:

9*12 = 108 inches

Now first of all, we have to see how many 15 inches pieces can be cut from one role

So,

[tex]=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2[/tex]

So the seamstress can cut 7 15-inch long pieces from a roll.

Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:

[tex]= 5 * 7 =35[/tex]

Hence,

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Step-by-step explanation

Given,

Total number of votes casted = 42,000

The winner received 3/5 of the votes.

To find,

How many votes did the winner not receive.

Solution,

Votes received by the winner is :

[tex]\dfrac{3}{5}\times 42000\\\\=25200[/tex]

Votes didn't received by the winner = Total votes - votes received

= 42,000 -25200

= 16800

Hence, 16800  votes is not received by the winner.

Answer:

The answers to the questions are well numbered below.

Step-by-step explanation:

We have arrival rate

λ = 7 in every 10 minutes = 0.7

Service time u = 7 minutes

1. Average time a car is in system

W = 1/u - λ

= 1/7-0.7

= 0.1587

= 0.16 to 2 decimal places

2. Average number of cars in system

= λ/u-λ

= 0.7/7-0.7

= 0.1111

= 0.11 to 2 decimal places

3. Average time that cars spend to receive service

= λ/u(u-λ)

= 0.7/7(7-0.7)

= 0.01587

= 0.016 to 2 decimal places

4. Average number of cars in line behind customer receiving service

= λ²/u(u-λ)

= 0.7²/7(7-0.7)

= 0.49/44.1

= 0.011 to 2 decimal places

5. Probability no cats at window

1-λ/u

= 1-0.7/7

= 0.9 = 9%

6. Percentage of time postal clerk is busy

= λ/u = 0.7/7 = 0.1 = 10%

7. Probability of exactly 2 cars

= λ²e^-λ/2!

= 0.7²e^-0.7/2!

= 0.1217

= 12.17%

Answer:

Solving the equation [tex]-\frac{7}{10}=\frac{3a}{4}-\frac{13}{20}[/tex] we get: [tex]\mathbf{a=-\frac{1}{15} }[/tex]

Step-by-step explanation:

We need to solve the equation:

[tex]-\frac{7}{10}=\frac{3a}{4}-\frac{13}{20}[/tex]

And find the value of a

Solving the equation: [tex]-\frac{7}{10}=\frac{3a}{4}-\frac{13}{20}[/tex]

First we will be Switching sides

[tex]\frac{3a}{4}-\frac{13}{20}=-\frac{7}{10}[/tex]

Now, for finding value of a we will be adding 13/20 on both sides

[tex]\frac{3a}{4}-\frac{13}{20}+\frac{13}{20}=-\frac{7}{10}+\frac{13}{20}[/tex]

[tex]\frac{3a}{4}=-\frac{7}{10}+\frac{13}{20}[/tex]

Now, on right hand side, Taking LCM of denominators i.e 10 and 20, we get 20 and simplifying:

[tex]\frac{3a}{4}=\frac{-7*2+13}{20}\\\frac{3a}{4}=\frac{-14+13}{20}\\\frac{3a}{4}=\frac{-1}{20}[/tex]

Now, multiply both sides by 4/3

[tex]\frac{3a}{4}\times \frac{4}{3} =\frac{-1}{20}\times \frac{4}{3}\\a=\frac{-1}{5}\times \frac{1}{3}\\a= \frac{-1}{15}[/tex]

So, solving the equation [tex]-\frac{7}{10}=\frac{3a}{4}-\frac{13}{20}[/tex] we get: [tex]\mathbf{a=-\frac{1}{15} }[/tex]

and

4+6=10

Answer:

A= –5x2 + 4x – 7y + 14 = 0

C= 9x2 – 12xy + 4y2 + 4x – y + 5 = 0

D= 12x + 6y – 5y2 + 14 = 0

Step-by-step explanation:

I finished the assignment from Edge2020

The equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,

[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]

If In this equation,

Either [tex]A=0[/tex] or [tex]B=0[/tex], but not both. Then it is the equation of parabola.

The first equation is,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

There is no square term of y. Thus, this is the equation of parabola.

The second equation is,

[tex]-x^2 + 6x + y^2 - 8 = 0[/tex]

This is not the equation of parabola, as there is two square terms of variable x and y.

The third equation is,

[tex]9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0[/tex]

Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.              

The fourth equation is,

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

This equation is the equation of parabola, as there is only a single square term.

The fifth equation is,

[tex]20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0[/tex]

This is now the equation of parabola because of two square terms.

Hence, the equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

Step-by-step explanation:

x = ky

Substitute the values of x and y to check if it's proportional. Then solve for k. If k is the same for all 4 equations, then 2 is proportional.

6 = -2k, k = 6/-2, k = -3

7 = -1k, k = 7 / -1, k = -7

8 = 0k, k = 8 / 0, k = 0

9 = k, k = 9

2 is not proportional.

Substitute the values of x and y to check if it's proportional. Then solve for k. If k is the same for all 4 equations, then 3 is proportional.

-70 = -10k, k = -70 / -10, k = 7

-56 = -8k, k = -56 / -8, k = 7

-14 = -2k, k = -14 / -2, k = 7

-7 = -k,  k = -7 / -1, k = 7

Step-by-step explanation:

B is the best example where substitution is the best method since you already have one where y = something and you can plug -2/7x + 11 into the bottom equation for y and solve it that way. A and C make you get x or y by itself first first substitution would work and D already gives you the answers. B is the best since its already set in that format.

Answer:

The unemployment rate would be 5.5%.

Step-by-step explanation:

It is given that,

The Canadian labor force as of 2019 was 32.7 million.

There were 30.9 million employed

We need to find the unemployment rate.

Unemployed = labor force - employed

= 32.7 - 30.9

= 1.8 million

[tex]\text{unemployment rate}=\dfrac{\text{unemployed}}{\text{labor force}}\times 100\\\\=\dfrac{1.8}{32.7}\times 100\\\\=5.5\%[/tex]

So, the unemployment rate would be 5.5%.

Answer: 18

Step-by-step explanation:

Answer:

a. [tex]f(a) = -0.03a +1.53[/tex]

b. See Explanation

c. The slope is reasonable but the p intercept is not

d. [tex]f(20) = 93\%[/tex]     [tex]f(30) = 63\%[/tex]    [tex]f(40) = 33\%[/tex]   [tex]f(50) = 3\%[/tex]

Step-by-step explanation:

Given

[tex]a = age[/tex]

[tex]p = probability\ of\ marriage[/tex]

[tex]a = 45[/tex] when [tex]p = 18\%[/tex]

[tex]a = 25[/tex] when [tex]p = 78\%[/tex]

Solving (a): The linear function

We start by calculating the slope, m

[tex]m = \frac{p_2 - p_1}{a_2 - a_1}[/tex]

[tex]m = \frac{78\% - 18\%}{25- 45}[/tex]

[tex]m = \frac{60\%}{-20}[/tex]

[tex]m = -3\%[/tex]

[tex]m = -0.03[/tex]

The function is then calculated as follows

[tex]p - p_1 = m(a - a_1)[/tex]

This gives:

[tex]p - 18\% = -0.03(a - 45)[/tex]

[tex]p - 0.18 = -0.03(a - 45)[/tex]

[tex]p - 0.18 = -0.03a +1.35[/tex]

Solve for p

[tex]p= -0.03a +1.35+0.18[/tex]

[tex]p= -0.03a +1.53[/tex]

Hence,

[tex]f(a) = -0.03a +1.53[/tex]

Solving (b): Interpret the slope and the p intercept

The slope is calculated as:

[tex]m = -0.03[/tex]

And it implies that, there is a 3% reduction in change of getting older as women get older

The p intercept implies that, there is a 1.53 chance for 0 years old female child to get married.

Solving (c): Is (b) reasonable

The slope is reasonable.

However, the p intercept is not because of the age of the woman

Solving (d): Determine f(20), f(30), f(40), f(50)

We have that:

[tex]f(a) = -0.03a +1.53[/tex]

[tex]f(20) = -0.03 * 20 + 1.53[/tex]

[tex]f(20) = -0.6 + 1.53[/tex]

[tex]f(20) = 0.93[/tex]

[tex]f(20) = 93\%[/tex]

[tex]f(30) = -0.03 * 30 + 1.53[/tex]

[tex]f(30) = -0.9 + 1.53[/tex]

[tex]f(30) = 0.63[/tex]

[tex]f(30) = 63\%[/tex]

[tex]f(40) = -0.03 * 40 + 1.53[/tex]

[tex]f(40) = -1.2 + 1.53[/tex]

[tex]f(40) = 0.33[/tex]

[tex]f(40) = 33\%[/tex]

[tex]f(50) = -0.03 * 50 + 1.53[/tex]

[tex]f(50) = -1.5 + 1.53[/tex]

[tex]f(50) = 0.03[/tex]

[tex]f(50) = 3\%[/tex]
