From the given scatter plot, finding a line of best fit, the estimate of the amount of prize money in year 10 of the contest is of $11,790.

To find the equation of the line of best fit, we need to insert the points (x,y) from the scatter plot in the calculator.

From the scatter plot, the points are given as follows:

(1, 9.5), (2,9), (3,7), (4,10), (5,11), (6, 10), (7, 10.5).

Inserting these points into a calculator, the line of best fit for the prize in year x is given as follows:

P(x) = 0.32143x + 8.28571

For year 10, we have that x = 10, hence:

P(10) = 0.32143(10) + 8.28571 = $11,500.

The closest option is $11,790, and the difference is due to rounding of coefficients or points in the table.

As Karen worked for 40 regular hours and 6hours overtime at the rate of 1.5 regular hours and her gross pay was $650 then her hourly rate is $13.27 (approximately).

As given,

Regular working hours =40 hours

Overtime at the rate of (1.5 of regular hours) = 6 hours

Gross pay =$650

Let 'h' be the hourly rate

Required equation

40h + 6(1.5h) =650

⇒ 40h +9h=650

⇒49h=650

⇒h=$13.27(approximately)

Answers:

Length = 45 feet

Width = 9 feet

=========================================================

Work Shown:

x = width

5x = five times the width = length

P = perimeter of the rectangle

P = 2*(length + width)

P = 2*(5x+x)

P = 2*(6x)

P = 12x

Set this equal to the stated perimeter (108) and solve for x.

12x = 108

x = 108/12

x = 9 feet is the width

5x = 5*9 = 45 feet is the length

-------------

Check:

P = 2*(9+45) = 108

or you could add up the four sides like this

P = 9+45+9+45 = 108

Either way the answers are confirmed.

Answer:

Step-by-step explanation:

You want the speed and speed multiplier for Jet B given that it makes a journey in 5 minutes that takes Jet A 2 hours for half the journey.

For the same distance, speed is inversely proportional to time.

  speed multiplier = (speed B)/(speed A) = (time A)/(time B)

  speed multiplier = ((2 h)/(1/2))/(5 min)

  speed multiplier = (240 min)/(5 min) = 48

The speed of Jet B is 48 times that of Jet A:

  48(417 mph) = 20016 mph . . . . speed of Jet B

__

Additional comment

The time for the full trip by Jet A can be found using the proportion ...

  partial time/partial distance = total time/total distance

If the total distance is "1 unit", then this proportion is ...

  (2 h)/(1/2) = t/1 . . . . . where t/1 = t is the time for the full trip by Jet A

You will recognize the value (2 h)/(1/2) as the time value we used for Jet A in the above solution.

Vertical asymptotes occur wherever the denominator is zero (but not necessarily when the numerator is also zero).

We have

[tex]\implies \cos\left(\dfrac{\pi x}4\right) = 0 \text{ or } x - 3 = 0 \text{ or } x - 5 = 0[/tex]

In the first case, we have

[tex]\cos\left(\dfrac{\pi x}4\right) = 0 \implies \dfrac{\pi x}4 = \pm\dfrac\pi2 + 2n\pi \implies x = \pm 2 + 8n[/tex]

The price of the jacket is $23.75

Let m be the price of a jacket and n be the price of pair of pants.

The total cost of a jacket and a pair of pants was $52.37

So, we get an equation,

m + n = 52.37              ................(1)

Also, the price of the jacket was $4.87 less than the pair of pants

So, we get an equation,

m = n - 4.87               .............(2)

Substitute above value of m in equation (1)

⇒ (n - 4.87) + n = 52.37

⇒ 2n - 4.87 = 52.37

⇒ 2n = 52.37 + 4.87

⇒ 2n = 57.24

⇒ n = 28.62

This means, the cost of a pair of pants is $28.62

Substitute above value of n in equation (2)

⇒ m = n - 4.87

⇒ m = 28.62 - 4.87

⇒ m = 23.75

This means, the cost of a jacket is $23.75

we end up paying 41.25 % of the original price after the addition sale on the clearance.

Let the original price of the good be x

Now, there is a sale of 25 %.

So the price will become

Price = x - 25 % of x

Price = x - 25 / 100 x

Price = x - 0.25 x

Price = 0.75 x

Now, there is an addition 45 % sale on the price.

so the price become:

New price = P = 0.75 x - 45 % of 0.75 x

P = 0.75 x - 45 / 100 (0.75 x)

P = 0.75 x - 0.45( 0.75 x)

The probability that no Tails is achieved on flipping a fair coin for three consecutive times is [tex](\frac{1}{8})[/tex].

As per the question statement, we are to flip or toss a fair coin thrice consecutively.

We are required to calculate the probability that no Tails is achieved during the above mentioned event.

To solve this question, first let us calculate all the possible outcomes of flipping a fair coin thrice consecutively. [We will denote a Heads outcome as "H" and a Tails outcome as "T"]

The total number of outcomes can be given by the formula [tex](2^{n})[/tex], where "n" is the number of times, the coin is tossed.

Here, (n = 3), therefore, total number of outcomes in our case [tex]=(2^{3})=8[/tex].

These 8 outcomes can be listed as [tex][{(H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T)}][/tex]

And among the above listed 8, our favorable outcome is (H, H, H), i.e., 1 favorable outcome of 8.

Hence, probability that no Tails is achieved on flipping a fair coin thrice consecutively = [tex]\frac{1}{8}[/tex].

Answer:

  1:30 pm

Step-by-step explanation:

You want the time when Sahil catches up to Joaquin, who left at 8 am riding 50 mph when Sahil left at 8:30 am, riding at 55 mph.

The relation between time, speed, and distance is ...

  distance = speed × time

  time = distance / speed

Joaquin has a head start of 0.5 hours (30 minutes), during which time he traveled ...

  head start distance = (50 mi/h) × (0.5 h) = 25 mi

Sahil is traveling 55 - 50 = 5 mph faster than Joaquin, so closes that gap at the rate of 5 mi/h. The time it takes to close the gap entirely is ...

  time = distance / speed = 25 mi / (5 mi/h) = 5 h

So, 5 hours after Sahil starts at 8:30, the two riders will be at the same place.

Sahil catches Joaquin at 1:30 pm.

__

Additional comment

By the time the gap is closed at 1:30 pm, both riders will have traveled a distance of ...

  distance = speed × time = 50 mi/h × 5.5 h = 55 mi/h × 5 h = 275 mi

In the attached graph, we have written equations for the total distance traveled by each motorcycle. The x-value used is the clock time on a 24-hour clock. That is, their meeting time of 13.5 hours corresponds to 13:30 hours or 1:30 p.m. on a 12-hour clock.

The cardinal number of (2, 4, 6, ..., 106) is 53.

The cardinal number of a set is the number of elements in the particular set.

We are given the set (2, 4, 6, ..., 106). As we can can clearly see, it is forming an Arithmetic Progression (AP).

Hence, let the number of elements or the cardinal number of the set be n.

Hence, according to the formula of AP, we can write,

2 + (n-1)(2) = 106

2(n-1) = 106 - 2

2(n-1) = 104

n - 1 = 104/2

n - 1 = 52

n = 52 + 1

n = 53
