Find the 5 number summary.

Answer:

Step-by-step explanation:

The available area is found by subtracting twice the border width from each of the overall lot dimensions. The accommodation that provides is found by dividing the area by the area required per dog.

__

The 10 foot setback from each lot line means the usable space has dimensions that are 20 feet shorter than the lot dimensions.

  usable rectangle = (120 ft -20 ft)×(80 ft -20 ft) = (100 ft)(60 ft)

  usable rectangle = 6000 ft²

There will be 6000 square feet in the smaller lot.

__

The space required for each dog is ...

  (12,500 ft²)/(50 dogs) = 250 ft²/dog

Then the number of dogs that can be accommodated in 6000 ft² is ...

  (6000 ft²)/(250 ft²/dog) = 24 dogs

The number of dogs allowed is 24.

The density curve is a type or way of representation of numbered distribution data over a graph. Here, the outcomes are continues. The density curve can not be below the x-axis or horizontal line of the graph.

In a density curve,

Records show that Oliver is typically 10-30 minutes late for his shift at work. The distribution for the minutes he is late forms a consistent pattern, which can be graphed as the given uniform density curve.

Oliver will get a written warning if he is more than 16 minutes late for work. The time remain after the 16 minutes is,

t=30-16

t=14 min

Thus, the percentage of the time will Oliver get a written warning is,

p=(14/30)*100

p=46.7 %

Thus, the percentage of the time will Oliver get a written warning when  he is more than 16 minutes late for his shift at work is 46.7%.

Answer:

Step-by-step explanation:

-7+(n-1)6

-7 is the starting term

n is the term that you are looking for

6 is the common difference

The formula for the nth term in the arithmetic sequence is:

a(n) = 6n - 13

It is a sequence where the difference between each consecutive term is the same.

We have,

We are given the first four terms of an arithmetic sequence:

a₁ = -7, a₂ = -1, a₃ = 5, a₄ = 11

To find the formula for the nth term, we need to find the common difference (d) first.

We can do this by subtracting any two consecutive terms:

d = a₂ - a₁ = (-1) - (-7) = 6

Now we can use the formula for the nth term of an arithmetic sequence:

a(n) = a₁ + (n - 1)d

Substituting the values we found:

a(n) = (-7) + (n - 1)(6)

Simplifying:

a(n) = -7 + 6n - 6

a(n) = 6n - 13

Therefore,

The formula for the nth term in the arithmetic sequence is:

a(n) = 6n - 13

Step-by-step explanation:

estimation of 6$+_+_?_!(_

Answer:

Step-by-step explanation:

Speed is the ratio of distance to time. Speeds can be compared by comparing the times for the same distance, or by comparing the distances for the same time. A faster speed means more distance is covered in less time.

__

Here, we observe that 68 feet is a multiple of 34 feet, so it is easiest to compare the speeds of the insects by comparing their times for the same distance.

  butterfly: 68 ft in 5 seconds

  dragonfly: 2×34 ft in 2×3 seconds, or 68 ft in 6 seconds

The butterfly covers the same distance in less time, so it can fly faster.

__

Since our comparison of speeds is made using travel times, we can say the answer to "how much faster" is "1 second less over a distance of 68 feet."

_____

Additional comment

You may be expected to figure the speeds in units of feet per second. You do that by dividing feet by seconds.

  butterfly: 68 ft/(5 s) = 13.6 ft/s

  dragonfly: 34 ft/(3 s) = 11 1/3 ft/s

The difference in speeds is ...

  (13 3/5) -(11 1/3) = 2 4/15 . . . ft/s

The butterfly's speed is 2 4/15 ft/s faster than the dragonfly's speed.

__

You see time comparisons in human foot races, often with differences measured in milliseconds. Almost never are speeds compared in terms of feet (or meters) per second.

Answer:

60 miles per hour.

Step-by-step explanation:

speed = distance / time

= 750 / 12.5

= 60 miles per hour.

Answer:

56

Step-by-step explanation:

To find the area of a rectangle we have the foruma A=WxL.

But we already have the area and length so we can plug that in

5488=Wx98

Now its an algebreic expression.

SInce its multiplying we do the opposite, so we divide 98 on both sides.

98/98 crosses itself out so now its 5488/98. Which equals 56. So now our expression is W=56. To fact check we put the numbers 56 and 98 into the formula to see if we get 5488.

A=56x98

A=5488

Answer:

see explanation

Step-by-step explanation:

the codomain are the values of f(x) from the y- coordinate of the vertex upwards.

given a quadratic in standard form

y = ax² + bx + c ( a ≠ 0 )

then the x- coordinate of the vertex is

[tex]x_{V}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = 2x² + 4x - 1 ← is in standard form

with a = 2 and b = 4 , then

[tex]x_{V}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1

substitute x = - 1 into f(x) for y- coordinate of vertex

f(- 1) = 2(- 1)² + 4(- 1) - 1 = 2 - 4 - 1 = - 3

vertex = (- 1, - 3 )

since the coefficient of the x² term > 0 then the graph opens up U

then codomain is [ - 3, ∞ )

Bias compare results implement treatments

Step-by-step explanation:

Write properties of function:

x intercept/zero: t₁ = -1, multiplicity 1; t₂ = 10 , multiplicity 1

vertex form: g (t) = (t - 9/2)² - 121/4

vertex: (9/2, -121/4)

The requried,
1. Zeros fo the function G(t) = (t – 10)(t + 1) are -1 and 10.
2. Vertex of the parabola is (9/2, -121/4).

A parabola is a cross-section cut out of the cone and represented by an equation G(t) = (t – 10)(t + 1.

Given function: G(t) = (t – 10)(t + 1)

1. To find the zeros of the function, we set G(t) to 0 and solve for t:

(t – 10)(t + 1) = 0

This gives us t = 10 and t = -1. Therefore, the smaller t is -1 and the larger t is 10.

So, the zeros of the function are:

smaller t = -1

larger t = 10

2.To find the vertex of the parabola, we can rewrite the given function in vertex form:

G(t) = (t – 9/2)² - 121/4

The vertex of the parabola is given by (h, k), where h is the x-coordinate and k is the y-coordinate. Therefore, the vertex of the parabola is:

Vertex: (9/2, -121/4)

Step-by-step explanation:

The "Frequency" part of a frequency table is the measure of how often the data value occurs.

To calculate the mean of data presented in a frequency table, we need to multiply each data value by its given frequency, sum these, then divide by the sum of the frequency.

The formula for mean is:

[tex]\textsf{mean}=\overline{x}=\dfrac{\displaystyle \sum fx}{\displaystyle\sum f}[/tex]

Add a row showing the values of [tex]fx[/tex]

Add a column showing the totals of [tex]f[/tex] and [tex]fx[/tex]

[tex]\large\begin{array}{| c | c | c | c | c | c | c | c |}\cline{1-8} & & & & & & & \sf Total \\\cline{1-8} x & 2 & 3 & 4 & 5 & 6 & 7 & \\\cline{1-8} \textsf{Frequency}\:f & 11 & 17 & 24 & 23 & 18 & 15 & 108\\\cline{1-8} fx & 22 & 51 & 96 & 115& 108 & 105 &497 \\\cline{1-8}\end{array}[/tex]

Now use the formula to calculate the mean:

[tex]\implies \textsf{mean}=\overline{x}=\dfrac{497}{108}=4.60\:\textsf{(2 dp)}[/tex]

Add a column showing the values of [tex]fx[/tex]

Add a row showing the totals of [tex]f[/tex] and [tex]fx[/tex]

[tex]\large\begin{array}{| c | c | c |}\cline{1-3} x & \textsf{Frequency}\: f & fx \\\cline{1-3} 0 & 35 & 0 \\\cline{1-3} 1 & 76 & 76\\\cline{1-3} 2 & 48 & 96\\\cline{1-3} 3 & 22 & 66 \\\cline{1-3} \sf Total & 181 & 238 \\\cline{1-3}\end{array}[/tex]

Now use the formula to calculate the mean:

[tex]\implies \textsf{mean}=\overline{x}=\dfrac{238}{181}=1.31\:\textsf{(2 dp)}[/tex]

Add a column showing the values of [tex]fx[/tex]

Add a row showing the totals of [tex]f[/tex] and [tex]fx[/tex]

[tex]\large\begin{array}{| c | c | c |}\cline{1-3} x & \textsf{Tally}\: f & fx \\\cline{1-3} 8 & 7 & 56\\\cline{1-3} 9 & 10 & 90\\\cline{1-3} 10 & 3 & 30\\\cline{1-3} \sf Total & 20 & 176\\\cline{1-3}\end{array}[/tex]

Now use the formula to calculate the mean:

[tex]\implies \textsf{mean}=\overline{x}=\dfrac{176}{20}=8.8[/tex]

Answer:

So our unknown width is X and the unknown length is X + 3.  We know the perimeter is 2 times the length plus 2 times the width so let's set up that equation:

2 X + 2 (X+3) = 24

Now solve for X

2 X + 2 X + 6 = 24

4 X + 6 = 24

4 X = 18

X = 4.5 - this is the width

X + 3 = 4.5 + 3 = 7.5 - this is the length
