Consider the following information:
Observations 1 2 3 4 5 6
Num. of defects 10 18 13 15 9 12
The number of runs above and below the sample median is:__________
a) 3.
b) 4.
c) none of these.
d) 5.
e) 6.
Answer:
A. 3Step-by-step explanation:
Formula for locating the Median of a grouped data = (N+1)/2 th where
N is the total number of defects.
Total defects = 10+18+13+15+9+12
Total defects = 77
Median value = (77+1)/2 th value
Median value = 78/2 = 39th value.
We will cummulate the frequency (number of defects up to the 38th value) and locate the corresponding observation value.
On cummulating:
10+18+13 = 41
We can see that the value of 38 falls on the third column(13), hence the median will be the equivalent number of observations i.e 3.
Therefore the sample median is 3

Lisa is framing a rectangular painting the length is three more than twice the width she uses 30 inches of framing material what is the length of the painting right and solve the equation
Answer:
The width is 4 inches
The length is 11 inches
Step-by-step explanation:
Let the width be x inches
Let the length be (2x+3 )inches
Perimeter= 30 inches
therefore, 2(length +breadth)= perimeter
=>2(2x+3+x)=30
=>2(3x+3)=30
=>6x+6=30
=>6x=30-6
=>6x=24
=>x=24/6
=>x=4
The width is 4 inches
The length is 11 inches
To solve this question:
First, we have to understand the concept of perimeter, and how it is calculated for a rectangle.Relating the length and the width of the triangle, and using this to solve the perimeter equation for the length.Doing this, we get that the length of the painting is: 11 inches.
Perimeter of a rectangle:
The perimeter of a polygon is the sum of it's sides.
For a rectangle, as the one given in the picture at the end of this answer, which is of the format of the painting, the perimeter is given by:
[tex]P = 2l + 2w[/tex]
Lisa is framing a rectangular painting the length is three more than twice the width.
This means that:
[tex]l = 3 + 2w[/tex]
Since we want to solve for the length, we write the width as a function of the length, thus:
[tex]2w = l - 3[/tex]
She uses 30 inches of framing material
This means that the perimeter is of 30 inches, that is:
[tex]2l + 2w = 30[/tex]
Since [tex]2w = l - 3[/tex]
[tex]2l + l - 3 = 30[/tex]
[tex]3l = 33[/tex]
[tex]l = \frac{33}{3}[/tex]
[tex]l = 11[/tex]
Thus, the length of the painting is of 11 inches.

Step-by-step explanation:
Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that are not satisfied. Recording the number of televisions in 150 households
Choose the correct answer below.
A. No, because the probability of success does not remain the same in all trials.
B. Yes, because all 4 requirements are satisfied.
C. No, because there are more than two possible outcomes and the trials are not independent.
D. No, because there are more than two possible outcomes.
Answer:
A. No, because the probability of success does not remain the same in all trials.
Step-by-step explanation:
In this procedure the number of televisions could vary in each house. Some people have one , two, even three or some may not have any. So the number of successes in each trial varies as the number of televisions varies.
Therefore, it is not a binomial distribution. It is necessary that for a binomial distribution the probability of success for each trial remains fixed.
A city council consists of six Democrats and seven republicans. If a committee of four people is selected, find the probability of selecting two Democrats and two Republicans.
Answer:
[tex]\bold{\dfrac{63}{143}}[/tex]
Step-by-step explanation:
Number of Democrats = 6
Number of Republicans = 7
Total number of members = 6+7 = 13
To find:
Probability of selecting two Democrats and two Republicans if 4 members are selected in the committee = ?
Solution:
This is a selection problem.
Total number of ways to select 4 members in the committee out of total 13 = [tex]_{13}C_4 = \dfrac{13\times 12\times 11\times 10}{4\times 3\times 2} = 715[/tex]
Number of ways to select 2 Democrats = [tex]_{6}C_2 = \dfrac{6\times 5}{2} = 15[/tex]
Number of ways to select 2 Republicans = [tex]_{7}C_2 = \dfrac{7\times 6}{2} = 21[/tex]
Number of ways to select 2 Democrats and 2 Republicans = 15 [tex]\times[/tex] 21 = 315

The $x$-intercept of a positively-sloped line is -5, and the area of the triangle formed by the line, the $x$-axis, and the $y$-axis is 10. What is the slope of the line?
Answer:
4/5 OR -4/5
Step-by-step explanation:
So, area of triangle = 1/2 * base * height
base = 5 (because x-axis is base, x-intercept is -5, so x-length = 5)
height is unknown
area = 10
We can form the equation: 1/2 * 5 * height = 10
Rearrange terms to get: height (y-height) = 10 / (0.5 * 5) = 4
Following the formula for gradient, dif in y / dif in x, we get 4/5
Therefore our gradient is (4/5), or 0.8.
But because we are only told the x-intercept, it can cross the y axis at y = 4 or y = -4. So there are actually 2 possible gradients, 4/5 and -4/5
At the movie theatre, child admission is $5.50 and adult admission is $8.60. On Wednesday, 131 tickets were sold for a total sales of $946.80 . How many adult tickets were sold that day?
Answer:
73
Step-by-step explanation:
Let a represent the number of adult tickets sold. Then the total revenue was ...
8.60a +5.50(131 -a) = 946.80
8.60a -5.50a +720.50 = 946.80 . . . . eliminate parentheses
3.10a = 226.30 . . . . . . subtract 720.50, collect terms
a = 73 . . . . . . . . . . . . . . divide by 3.10
73 adult tickets were sold that day.

h(x)=x2+1 k(x)=x-2
(h-k)(3)
Answer:
(h-k)(3) = 9Step-by-step explanation:
h(x) = x² + 1
k(x) = x - 2
To find (h-k)(3) we must first find (h - k)(x)
To find (h - k)(x) subtract k(x) from h(x)
That's
(h - k)(x) = x² + 1 - ( x - 2)
(h - k)(x) = x² + 1 - x + 2
(h - k)(x) = x² - x + 1 + 2
We have
(h - k)(x) = x² - x + 3
To find (h-k)(3) substitute the value of x that's 3 into (h - k)(x) that's replace every x in (h - k)(x) by 3
We have
(h-k)(3) = (3)² - 3 + 3
= 9 - 3 + 3
= 9 - 0
We have the final answer as
(h-k)(3) = 9Hope this helps you

What are the two types of hypotheses used in a hypothesis test? type I and type II null and alternative Your answer is correct. left-tailed and right-tailed population and sample How are they related? They sum to zero. One is a subset of the other. They are equal. They are complements.
Answer:
There are two types of hypotheses tests. null and alternative
They are complements.
Step-by-step explanation:
There are two types of hypotheses tests. null and alternative
the table shows the summary of both tests.
True Situation DECISION
Accept H0 Reject H0
(or accept Ha)
H0 is true Correct decision Wrong Decision
(no error) type I error
H0 is false Wrong Decision Correct decision
type II error ( no error)
The probability of making a type I error is conventionally denoted by alpha and that of committing a type II error is indicated by beta.
∝ = P ( type I error) = P (reject H0 / H0 is true)
β = P (type II error) = P (accept H0 / H0 is false)
When ∝ becomes larger, β tends to become smaller . There is inverse relationship between ∝ and β.
When H0 is true Ha is false when Ha is false H0 is true. So they are compliments of each other.
Find the rate of change and describe it in context. # of tickets 5, 6, 7, 8 Total cost 75, 90, 105, 120
Answer:
The cost of 1 ticket is 15 dollars
Step-by-step explanation:
The rate of change is another word for slope
m = (y2-y1)/(x2-x1)
= (90-75)/(6-5)
= 15/1
The cost of 1 ticket is 15 dollars
The rate of change is a ratio that compares the change in y/change in x.
We can see that the y-values increase by 15 each time and
we can see that the x-values increase by 1 each time.
So the change in y/change in x is 15/1.
This means that for every ticket bought, you pay $15.
The length of a rectangle is five times its width.

Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{125 \: {cm}^{2} }}}}}[/tex]
Step-by-step explanation:
Let the width be 'w'
Length of a rectangle = 5w
Perimeter of a rectangle = 60 cm
Area of a rectangle = ?
First, finding the value of width ' w '
[tex] \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}[/tex]
plug the values
⇒[tex] \sf{60 = 2(5w + w)}[/tex]
Distribute 2 through the parentheses
⇒[tex] \sf{60 = 10w + 2w}[/tex]
Collect like terms
⇒[tex] \sf{60 = 12w}[/tex]
Swap the sides of the equation
⇒[tex] \sf{12w = 60}[/tex]
Divide both sides of the equation by 12
⇒[tex] \sf{ \frac{12w}{12} = \frac{60}{12} }[/tex]
Calculate
⇒[tex] \sf{w = 5}[/tex] cm
Finding the value of length ( l )
[tex] \sf{length = 5w}[/tex]
Substitute the value of w
⇒[tex] \sf{length = 5 \times 5}[/tex]
⇒[tex] \sf{length = 25 \: cm}[/tex]
Finally, Finding the area of rectangle having length of 25 cm and width of 5 cm
[tex] \boxed{ \sf{area \: of \: a \: rectangle = l \times b}}[/tex]
plug the values
⇒[tex] \sf{area \: = \: 25 \times 5}[/tex]
Multiply the numbers
⇒[tex] \sf{area \: = \: 125 \: {cm}^{2} }[/tex]

(c) Find the probability that at least one of the two adults thinks most celebrities are good role models. The probability that at least one of the two adults thinks most celebrities are good role models ______? (Round to three decimal places as needed.)
Answer:
A) 0.062
B)0.564
C)0.436
Step-by-step explanation:
There are 800 US adults sampled and 199 think that most celebrities are good role models.
Now, two are selected without replacement.
Thus;
A) Probability that both adults think most celebrities are good role models would be = (199/800) × (198/799) = 39402/639200 = 0.062
B) we want to find probability that neither adult thinks most celebrities are good role models.
Now, since 199 out of 800 think that most celebrities are good role models..
Thus, number that doesn't think most celebrities are good role models = 800 - 199 = 601
probability that neither adult thinks most celebrities are good role models. would be = (601/800) × (600/799)= 180300/319600 = 0.564
C) We want to find the probability that at least one of the two adults thinks most celebrities are good role models.
Now, since we already have the probability that neither of them thinks most celebrities are good role models, we will just subtract that probability from 1.
Thus;
probability that at least one of the two adults thinks most celebrities are good role models = 1 - 0.564 = 0.436
