From the graph of the function, determine the domain and the range.

Answer:

Median = $179,000

Step-by-step explanation:

Given prices of the houses :

$172,000 , $164,000 , $142,000 , $159,000 , $191,000 , $124,000 , $146,000

Arrange the data in ascending order :

$124,000 , $142,000 , $146,000 , $159,000, $164,000 , $172,000, $191,000

Prices according to the public assessor :

$144,000 , $162,000 , $166,000 , $179,000 , $184,000, $192,000, $211,000

Median is the middle value in the data : $179,000

Answer:

Explained below

Step-by-step explanation:

A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.

B) If in a data set, there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.

Also, if the curve is inclined to the left, it means there are few extreme values to the left and is is negatively skewed.

Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.

C) Example of a research question is;

If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data to is positively skewed.

The number line (d) represents the values of x that makes -3x + 1 < 7 to be true

The inequality is given as:

-3x + 1 < 7

Subtract 1 from both sides

-3x < 6

Divide both sides by -3

x > -2

This means that the number line must show an inequality that is greater than -2

From the list of options, the number line that represents x > -2 is (d)

Hence, the number line (d) represents the values of x that makes -3x + 1 < 7 to be true

Answer:

A

Step-by-step explanation:

it takes 45 hours to plant 100 trees, so his rate is 100/45 trees per hour.

and it takes rose 40 hrs to plant the 100 trees, so her rate is 100/40 trees per hour

So add those together to get (100/45+100/40)

and then multiply them by P(which is in hours) to equal 100

(100/45+100/40)p=100

then divide by 100 both sides to get

p/45+p/40=1

Given:

The figure of a right angle triangle with legs a and 7, and hypotenuse c.

The measure of angle opposite to leg 7 is 30^\circ.

To find:

All the missing measures for the triangle.

Solution:

According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees. So,

[tex]30^\circ+90^\circ+\text{Missing angle}=180^\circ[/tex]

[tex]120^\circ+\text{Missing angle}=180^\circ[/tex]

[tex]\text{Missing angle}=180^\circ-120^\circ[/tex]

[tex]\text{Missing angle}=60^\circ[/tex]

In a right angle triangle ,

[tex]\sin\theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin (30^\circ)=\dfrac{7}{c}[/tex]

[tex]\dfrac{1}{2}=\dfrac{7}{c}[/tex]

[tex]c=7\times 2[/tex]

[tex]c=14[/tex]

In a right angle triangle,

[tex]\tan \theta =\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan (30^\circ)=\dfrac{7}{a}[/tex]

[tex]\dfrac{1}{\sqrt{3}}=\dfrac{7}{a}[/tex]

[tex]a=7\times \sqrt{3}[/tex]

[tex]a=7\sqrt{3}[/tex]

Therefore, the measure of the missing angle is 60 degrees. Side "a" has a length of 14 units and side "c" has a length of [tex]7\sqrt{3}[/tex] units.

Answer:

Step-by-step explanation:

Answer:

a) 0.2087 = 20.82% probability that the number of U.S. adults who have very little confidence in newspapers is exactly​ five.

b) 0.1834 = 18.34% probability that the number of U.S. adults who have very little confidence in newspapers is at least​ six.

c) 0.3575 = 35.75% probability that the number of U.S. adults who have very little confidence in newspapers is less than four.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have very little confidence in newspapers, or they do not. The answers of each adult are independent, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

​41% of U.S. adults have very little confidence in newspapers.

This means that [tex]p = 0.41[/tex]

You randomly select 10 U.S. adults.

This means that [tex]n = 10[/tex]

(a) exactly​ five

This is [tex]P(X = 5)[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{10,5}.(0.41)^{5}.(0.59)^{5} = 0.2087[/tex]

0.2087 = 20.82% probability that the number of U.S. adults who have very little confidence in newspapers is exactly​ five.

(b) at least​ six

This is:

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 6) = C_{10,6}.(0.41)^{6}.(0.59)^{4} = 0.1209[/tex]

[tex]P(X = 7) = C_{10,7}.(0.41)^{7}.(0.59)^{3} = 0.0480[/tex]

[tex]P(X = 8) = C_{10,8}.(0.41)^{8}.(0.59)^{2} = 0.0125[/tex]

[tex]P(X = 9) = C_{10,9}.(0.41)^{9}.(0.59)^{1} = 0.0019[/tex]

[tex]P(X = 10) = C_{10,10}.(0.41)^{10}.(0.59)^{0} = 0.0001[/tex]

Then

[tex]P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) = 0.1209 + 0.0480 + 0.0125 + 0.0019 + 0.0001 = 0.1834[/tex]

0.1834 = 18.34% probability that the number of U.S. adults who have very little confidence in newspapers is at least​ six.

(c) less than four.

This is:

[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{10,0}.(0.41)^{0}.(0.59)^{10} = 0.0051[/tex]

[tex]P(X = 1) = C_{10,1}.(0.41)^{1}.(0.59)^{9} = 0.0355[/tex]

[tex]P(X = 2) = C_{10,2}.(0.41)^{2}.(0.59)^{8} = 0.1111[/tex]

[tex]P(X = 3) = C_{10,3}.(0.41)^{3}.(0.59)^{7} = 0.2058[/tex]

So

[tex]P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.0051 + 0.0355 + 0.1111 + 0.2058 = 0.3575[/tex]

0.3575 = 35.75% probability that the number of U.S. adults who have very little confidence in newspapers is less than four.

Answer:

[tex]x-9[/tex]

Step-by-step explanation:

[tex]side_1=2x+5\\side_2=x+3\\side_3=\phi\\perimeter=\displaystyle\sum_{i=1}^3side_i=(2x+5)+(x+3)+\phi=4x-1\\\phi=4x-1-x-3-5-2x=x-9[/tex]

The length of the third side in terms of x is x+1.

The perimeter of a triangle is the sum of all its three sides.

We can work out the perimeter using the following formula:

The perimeter of a triangle is = sum of all three sides.

The length of the third side in terms of x is given by;

[tex]\rm Perimeter \ of \ triangle = Side \ a + Side \ b + Side \ c[/tex]

Substitute all the values in the formula

[tex]\rm Perimeter \ of \ triangle = Side \ a + Side \ b + Side \ c\\\\4x-1=2x-5+x+3+Side \ c\\\\4x-1=3x-2+Side \ c\\\\Side \ c=4x-3x-1+2\\\\Side \ c=x+1[/tex]

Hence, the length of the third side in terms of x is x+1.

Answer:

Cost for 25 songs: $23.50

Cost for s songs: .50(s) + 11

Step-by-step explanation:

To solve this problem, we can make an equation in slope-intercept form:

y = mx + b

y represents the total amount of $.

m represents the cost of each song downloaded, or $.50

x represents the number of songs, or 's'

b represents the $11, or the constant.

We have the equation:

y = .50(x) + 11

If Angel downloaded 25 songs, we have the equation:

y = .50(25) + 11

We get y = $23.50

Answer:

$4080 / 30days

Step-by-step explanation:

In 7 days, Kendall earns $952

In 1 day, she will earn $952 ÷ 7 = $136

Therefore, the rate (r) at which she earns is $136/day. i.e

r =  $136/day               ---------------(i)

To write the rate as a fraction with 30 in the denominator, we multiply both the numerator and denominator of equation (i) by 30 as follows;

r =  $(136x30) / 30 day

r = $4080/30days

6 1/4

Step-by-step explanation:

When you look at the bar graph at the top, you will see that there are 5 of 1 1/4.

If you multiply 5 by 5/4 (which is 1 1/4 converted to an improper fraction), you get 25/4. To convert that to a mixed number, divide 25 by 4 and put the remainder over 4. The final answer should be 6 1/4.

For the X's, just count how many of each number is in the graph above. For example, there should be 2 X's over 1, 5 X's over 1 1/4, 2 X's over 1 1/2, and 2 X's over 1 3/4.
