Answer:

Median = $80,000 ; Mean = $84,000 ; Q1 = 67,000 ; Q3 = 106,000

Step-by-step explanation:

Given the data :

108 83 106 73 53 85 80 63 67 75 124 55 93 118 77

Reorderd data :

53, 55, 63, 67, 73, 75, 77, 80, 83, 85, 93, 106, 108, 118, 124

The median salary:

1/2(n+1)th term

Sample size, n = 15

1/2 (15 + 1)th term

1/2(16)th term

8th term = 80

Median is $80,000

Median reported by Wall Street Journal approximately $85000

The obtained and reported values are close

The mean annual salary :

ΣX / n = 1260 / 15 = 84

Mean annual salary = $84,000

Mean is the average of all earnings combined, median is the mid value of he data.

First and third quartile :

Q1 = 1/4(n+1)th term

Q1 = 1/4(16)th term

Q1 = 4th term = 67

Third quartile:.

Q3 = 3/4(n+1)th term

Q3 = 3/4(16)th term

Q3 = 12th term = 106

Answer:

8 quarts

Step-by-step explanation:

Step One: Figure out how much 40% is by making an equation:

Since we are looking for a percentage, we use cross multiplication to find X.

[tex]\frac{x}{20} = \frac{40}{100}[/tex]

Step Two: multiply 20 by 40 to start cross multiplying:

20 times 40 is 800, so replace the 40 by 800 in the equation.

[tex]\frac{x}{20} = \frac{800}{100}[/tex]

Step Three: divide 800 by 100, and we will have X:

800/100=8

X=8 aka 8 quarts

Answer:

Mochi

Step-by-step explanation:

Mochi

Each week theres a increase of 4 in Mochi's weight. So you will add 4 twice to get to the 5th week.

4th week : 17

5th week : 21

Kappa

In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at.

on the 3rd week Kappa weighed 11

and 2nd week Kappa weighed 5

and 1st week Kappa weighed 3

Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier.

Answer:

f(-4)=3(-4)-8

f(-4)=-12-8

f(-4)=-20

f(2)=3(2)-8

f(2)=6-8

f(2)=-2

f(7)=3(7)-8

f(7)=21-8

f(7)=13

R=(-20, -2, 13)

The range of the function when  f(x) = 3x - 8 and the domain is {-4, 2, 7) is (-20, -2, 13).

Since

f(-4)=3(-4)-8

f(-4)=-12-8

f(-4)=-20

Now

f(2)=3(2)-8

f(2)=6-8

f(2)=-2

Now

f(7)=3(7)-8

f(7)=21-8

f(7)=13

So,

R=(-20, -2, 13)

Answer

x - 2y = -1.

Step-by-step explanation:

Slope = (3 - (-2)) / (5 - (-5))

= 5/10

= 1/2

Using the point-slope form of a straight line equation:

y - y1 = m(x - x1)

Here m = 1/2 and (x1, y1) = (5, 3):

y - 3 = 1/2(x - 5)

y - 3 = 1/2x - 5/2

y = 1/2x  - 5/2 + 6/2

y = 1/2x +  1/2

Removing the fractions:

2y = x  + 1

in standard form this is

x - 2y = -1

Step-by-step explanation:

The probability for exact 4 chickens being infected out of the 7 is ⁷C₄(0.15)⁴(0.85)³. The correct option is (A).

The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.

In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.

Given that,

The probability of the infected chicken is 15%.

Which can be written as,

P(infected) = 15%

                  = 15/100

                  = 0.15

Then, the probability of not getting infected chicken is,

P(not infected) = 1 - 0.15

                        = 0.85

The total number of chicken for test = 7.

Now, in order to find the probability of the exact 4 infected chickens, binomial distribution can be used as.

The general expression for binomial distribution is ⁿCₓpˣqⁿ⁻ˣ.

For the given case p = P(infected) and q = P(not infected), n = 7 and x = 4.

Thus, the probability is given as,

P(Exact 4 are infected) = ⁷C₄(0.15)⁴(0.85)³

Hence, the  probability that exactly 4 of the 7 chickens sampled have the virus is  ⁷C₄(0.15)⁴(0.85)³.

Answer:

C. 6,900 ft^2

Step-by-step explanation:

Given the following data;

Base of triangle = 120 feet.

Height = 115 feet.

To find the area of triangle;

Area of triangle = ½*base*height

Area of triangle = ½*120*115

Area of triangle = 60*115

Area of triangle = 6900ft²

Therefore, the area of the park is 6900 square feet.

Answer:

The angle of elevation of the pile is 30°

Step-by-step explanation:

Given that;

Height = 15 ft

Diameter = 52 ft

so radius r = D/2 = 52/2 = 26 ft

Now, to get the angle of elevation.

given the details in the question,

we can say; the given height is the opposite which is 15 ft.

Also the radius is adjacent which is 26 ft

using SOH CAH TOA

TOA; Tan = Opposite / Adjacent

so

tan∅ = 15 ft / 26 ft

tan∅ = 0.5769

∅ = tan⁻¹( 0.5769 )

∅ = 29.98° ≈ 30°

Therefore, The angle of elevation of the pile is 30°

The pie chart will show that Claire spent about 33.3% of her time sleeping.

Pie chart will show that Claire spent about 33.3% of her time sleeping, The pie chart will have five sections, Twenty-four hours will be equivalent to 100% in the pie chart.

The "pie chart," which divides the circular statistical graphic into sectors or sections to illustrate the numerical problems, is also known as a "circle chart." A proportionate portion of the total is denoted by each sector. At that point, the pie chart is the most effective method for determining something's composition.

Given 24 hours schedule of Clair in which,

school time is 8 hours, playing time is 4 hours, homework time is 2 hours, sleeping time is 8 hours and chores time is 2 hours.

if we calculate total time in percentage than 24 hours will be equal to 100%

and their will be 5 sections in chart,

equivalent time for school in percent is 100/24 x 8 =33.33%

equivalent time for sleeping in percent is 100/24 x 8 =33.33%

equivalent time for homework in percent is 100/24 x 2 = 8.33%

equivalent time for chores in percent is 100/24 x 2 = 8.33%

equivalent time for playing in percent is 100/24 x 4 = 16.66%

Hence the pie chart will have 5 sections and sleeping time will be 33.33%.

Answer:

[tex](x+12)^2+(y-5)^2=80[/tex]

Step-by-step explanation:

First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is [tex]\sqrt{4^2+8^2}=\sqrt{80}[/tex].

The equation of a circle with diameter endpoints of (-14,1) and (-10,9) are;

(x+1)²+(y-4)²=348.

The standard form of the equation of a circle is (x - h)² + (y - k)² + r², where (h, k) is the center of the circle, and r is its radius.

Find the distance AB

d=√[(9 + 14)²+(-10 - 1)²]

d=√[576+121]

d=√697 units

The diameter=√697 units

r=√697/2  unit

Thus, the center of the circle is (-1,4)

Hence, the equation of a circle

(x-h)²+(y-k)²=r²

(x+1)²+(y-4)²=(√697/2)²

(x+1)²+(y-4)²=348

Answer:

The chance that the usual language in that household will NOT be English = 0.4

Step-by-step explanation:

As given ,

Total households in which languages spoken is English = 180

Total households in which languages spoken is Spanish = 80

Total households in which languages spoken is other than English or Spanish  = 40

So,

Total households = 180 + 80 + 40 = 300

Now,

Household in which English language is not spoken = 80 + 40 = 120

So,

The chances that the usual language in that household will NOT be English = [tex]\frac{120}{300} = \frac{12}{30} = \frac{4}{10} = 0.4[/tex]

∴ we get

Answer:

CD = 8 cm

Step-by-step explanation:

Given

See attachment

[tex]AE=6 cm,\ ED=4 cm,\ AB=4.5 cm,\ BE=4.8 cm.[/tex]

Required

Find CD

To calculate CD, we first calculate BC using the following equivalent ratio

[tex]AB : BC = AE:ED[/tex]

Substitute values for AB, AE and ED

[tex]4.5 : BC = 6 : 4[/tex]

Express as fraction

[tex]\frac{4.5 }{ BC} = \frac{6 }{ 4}[/tex]

Cross Multiply

[tex]BC * 6 = 4.5 * 4[/tex]

[tex]BC * 6 = 18[/tex]

Divide through by 6

[tex]BC = 3[/tex]

To calculate CD,

We make use of the following equivalent ratio

[tex]AB : BE = AC : CD[/tex]

Where

[tex]AC = AB + BC[/tex]

[tex]AC = 4.5 + 3[/tex]

[tex]AC = 7.5[/tex]

So, we have:

[tex]AB : BE = AC : CD[/tex]

[tex]4.5 : 4.8 = 7.5 : CD[/tex]

Express as fraction

[tex]\frac{4.5 }{ 4.8 }= \frac{7.5 }{ CD}[/tex]

Cross Multiply

[tex]4.5 * CD = 7.5 * 4.8[/tex]

Divide through by 4.5

[tex]CD = \frac{7.5 * 4.8}{4.5}[/tex]

[tex]CD = \frac{36}{4.5}[/tex]

[tex]CD = 8[/tex]

Answer:

a. 68%

b. 99.7%.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 246.8

Standard deviation = 67.2

a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the​ mean, or between 179.6 and 314.0​?

By the Empirical Rule, approximately 68%.

b. What is the approximate percentage of women with platelet counts between 45.2 and 448.4​?

45.2 = 246.8 - 3*67.2

448.4 = 246.8 + 3*67.2

Within 3 standard deviations of the mean, so approximately 99.7%.
