Answer 1

Answer:

90.3 km

Step-by-step explanation:

2 cm: 21 km and the boss provides 8.6 cm for manhattan-bronx distance.

a ratio can also be written as a fraction

2/21 x 8.6/x  or  2:21 and 8.6:x [cross multiply to solve for x]

2 x 8.6      =     2x = 180.6    =   2x = 180.6  reduces to x =90.3

Answers

Assuming that Clarence repaired the eight transmissions using 2 days, he will likely repair 24 transmissions if he works for the next 6 days.

What is a proportion?

A proportion shows the relationship between two or more ratios or quantities.

Data and Calculations:

Number of transmissions repaired in 2 days = 8

Number of days to repair more transmissions = 6

Estimated number of transmissions to be repaired = 24 (8/2 x 6)

Use quadratic regression to find the
equation for the parabola going
through these 3 points.
(2, 19) (6, 99) (-1, 1)

Answers

Answer:

The equation for the parabola is [tex]y = 2\cdot x^{2}+4\cdot x +3[/tex].

Step-by-step explanation:

Let be [tex]P(x,y) = (2, 19)[/tex], [tex]Q(x,y) = (6,99)[/tex] and [tex]R(x,y) = (-1, 1)[/tex] and quadratic regression is represented by a second-order polynomial of the form:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)

Where:

[tex]x[/tex] - Independent variable

[tex]y[/tex] - Dependent variable

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients

Algebraically speaking, we need three distinct points on plane to determine the quadratic regression. By using all information, we form the following system of linear equations:

[tex]4\cdot a +2\cdot b + c = 19[/tex] (2)

[tex]36\cdot a + 6\cdot b + c = 99[/tex] (3)

[tex]a -b + c = 1[/tex] (4)

The solution of this system is: [tex]a = 2[/tex], [tex]b = 4[/tex], [tex]c = 3[/tex]. Hence, the equation for the parabola is [tex]y = 2\cdot x^{2}+4\cdot x +3[/tex].

Write an equation of the line that passes through a pair of points: (2, 3), (4, -2)

To find the slope simply plug in the points, [tex]\frac{-2-3}{4-2}[/tex] which equals -5/2. Next, put the equation into slope-point form, which is [tex]y-y_{1} = m(x-x_{1})[/tex]. I will use the point (2,3). y-3=-5/2(x-2), then solve for y which equals y=-5/2+8.

Step-by-step explanation:

First, find the slope using the slope formula, [tex]\frac{0-6}{-10-0}[/tex]. This is 6/10, which simplifies to 3/5 or 0.6. Then you need to find the y-intercept, however, this is already given to you. Remember that the y-intercept is when x=0, so (0,6) must be the y-intercept. Therefore the equation is y=0.6+6.

An architect increases the radius of a circle window by 20 percent. By what percent
did the area of the circle window increase?

Answers

Answer: 44%

Step-by-step explanation:

For a circle of radius R, the area is written as:

A = pi*R^2

Where pi = 3.14

If we increase the radius by 20%, the new radius will be:

R´ = R + 0.20*R = 1.20*R

The new area will be:

A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2

   = 1.44*pi*R^2

And pi*R^2 = A, the original area, then_

A´ = 1.44*A = A + 0.44*A

This means that the percentage in which the area increased is:

0.44*100% = 44%

Answer:

Step-by-step explanation:

The temperature outside Monday morning was -14. On Tuesday morning it was 4 degrees colder. Create an equation to show temperature on Tuesday morning

Answers

Answer:

Temperature on Tuesday morning is [tex]-18^{o}[/tex].

Step-by-step explanation:

Temperature is the measure in degrees how cold or hot a substance is. The three scale of measurements are: Celsius, Fahrenheit, and Kelvin.

In the given question, temperature on Monday morning is -14 degrees. Since it was given that the temperature on Tuesday morning is 4 degrees colder than that of Monday, then;

Temperature on Tuesday = -14 + (-4)

                                          = -14 -4

                                          = -18

Therefore, the temperature on Tuesday morning is [tex]-18^{o}[/tex].

Answer:

Step-by-step explanation:

At a certain company, loan agents are paid based on the number of loans they close in a day. Based on company records, the number of loans X that a randomly selected loan agent closes on a randomly selected day has the probability distribution below.x 1 2 3 4 5 6 7p(x) 0.05 0.10 0.22 0.30 0.18 0.12 0.03 At the company, the daily salary of a loan agent is $150 plus $50 per loan closed. Let YY represent the amount of money made by a randomly selected loan agent on a randomly selected day. Which of the following statements is NOT true?A. The mean of X is less than the mean of Y. B. The standard deviation of Y is approximately $71. C. The mean daily salary is greater than $350 per day. D. The standard deviation of X is less than the standard deviation of Y. E. The shape of the probability distribution of Y is unimodal and roughly symmetric.

Answers

Answer:

C. The mean daily salary is greater than $350 per day

Step-by-step explanation:

The computation is shown below:

Y = a + bX

where,

Y = money made by a random selected

a = $150

b = $50

X = number of loan

Now

E(x) = (1 × 0.05) + (2 × 0.10) + (3 × 0.22) + (4 × 0.30) + (5 × 0.18) + (6 × 0.12) + (7 × 0.03)

= 3.94

Now

E(y) = $150 + ($50 × 3.94)

= $347

hence, the option C is not correct

The mean daily salary is greater than $350 per day and this can be determined by using the given data.

Given :

At a certain company, loan agents are paid based on the number of loans they close in a day.

The computation is given by:

Y = a + bX

where Y is the money made by randomly selected, a is $150, b is $50, and X is the number of loans.

Now, the value of E(x) is given by:

[tex]\rm E(x) = (1\times 0.5)+(2\times 0.1)+(3\times 0.22)+(4\times 0.3)+(5\times 0.18)+(6\times 0.12)+(7\times 0.03)[/tex]

[tex]\rm E(x) = 3.94[/tex]

Now, the value of E(y) is given by:

[tex]\rm E(y) = 150+(50\times 3394)[/tex]

E(y) = $347

So, the correct option is given by C) The mean daily salary is greater than $350 per day.

12+2(6 divided by 2/3) + 3.75

Answers

Answer:

33.75

Step-by-step explanation:

6 Luiz, Seth and Fran share £1440 in the ratio 3:5:7. Fran splits her share with her sister Ali in the ratio 4:1.
a) How much does each person end up with?
b) Find the ratio of the amount that Fran ends up with to the amount that Seth ends up with.
Give your answer in its simplest form.

Answers

Answer:

A) £1440 in the ratio of 3:5:7 is - £288: £480: £672

After Fran gives her sister Ali a share in the ratio 4:1, Fran was left with £537.60 and her sister was left with £134.40

B) Fran to Seth = £537.60: £480 → £28: £25

Step-by-step explanation:

To find 1 part of £1440 in the ratio of 3:5:7 you have to add 3+5+7= 15

Then you divide £1440 by 15 which is = £96

Next you take 96 and times it by 3 then 5 then 7 and put it in the ratio 3:5:7= £288: £480: £672

To find out how much Fran and her sister Ali end up with you have to add 4 & 1 = 5

Then divide Fran’s share, £672, by 5= £134.40

£134.40 is Ali’s share and now we need to find Fran’s by multiplying £134.40 by 4 which is= £537.60

F: A = £537.60: £134.40

As we now know Fran is left with £537.60 and we have to put that into a ratio with what Seth has. Earlier we found out that Seth has a total of £480 from the original share (£1440). If we put this knowledge into a ratio it becomes:

£537.60: £480

But we need to simplify them. So we need to change the values to whole number.

Convert any decimal numbers to integers by multiplying both sides by 101 = 10 to eliminate all, 1, decimal places. We then have: 480: 537.6 = 4800: 5376

Try to reduce the ratio further with the highest common factor (HCF). The HCF in our case is 192.

We need to divide both terms by the HCF:

4800 ÷ 192= 25

5376 ÷ 192= 28

Answer:

Step-by-step explanation:

Since we don't know how much each one of them gets, we will call that unknown amount x. Luiz gets 3x of the total amount, Seth gets 5x of the total amount, and Fran gets 7x of the total amount. The total amount is 1440, so the equation to find out how much that unknown amount x is looks like this:

3x + 5x + 7x = 1440 and

15x = 1440 so

x = 96.

That means that Luiz gets 3(96) = 288,

Seth gets 5(96) = 480,

and Fran gets 7(96) = 672. But Fran shares her portion in the ratio 4:1 with her sister. That's a separate equation that looks like this:

4x + 1x = 672 and

5x = 672 so

x = 134.40

That means that Ali gets 134.40, leaving Fran with 537.60.

That answers a. Now for b, the ratio of Fran's portion (what she's left with, at least) to Seth's is the fraction

[tex]\frac{537.60}{480}=\frac{28}{25}[/tex] or in decimal form, 1.12

Step-by-step explanation:

Given function to us is ,

[tex]\implies y = 5x^2 + 10 [/tex]

And, we need to find the inverse of the equation.

So , for that firstly replace x with y . The equation becomes

[tex]\implies x = 5y^2 + 10 [/tex]

Now , next we need to solve for y .

[tex]\implies x = 5y^2 + 10 \\\\\implies 5y^2 = x - 10 \\\\ \implies y^2 = \dfrac{x-10}{5} \\\\\implies y = \sqrt{\dfrac{x-10}{5}} [/tex]

Now , replace y for [tex]f^{-1}(x)[/tex]
