Make a conditional relative frequency table for the columns of movie type. Determine which statement has the strongest association.
Do you prefer watching a comedy, a drama, or a thriller movie?
Comedy Drama Thriller Row Totals
Males 35 12 75 122
Females 46 65 18 129
Column Totals 81 77 93 251
Males prefer comedy movies.
Females prefer drama movies.
Males prefer thriller movies.
Females prefer thriller movies.
The statement which has the strongest association is Males prefer thriller movies.
To obtain which statement has the strongest association, we calculate the probability of each given statement and select that which has the highest probability value.
• probability of Males prefer comedy movies :
n(males who prefer comedy) / n(males)
= 35 / 122 = 0.287
• probability of Females prefer drama movies :
n(Females who prefer drama) / n(females )
= 65 / 129 = 0.504
• probability of Males prefer thriller movies.
n(males who prefer prefer thriller ) / n(males)
= 75 / 122 = 0.615
• probability of Females prefer thriller movies.
n(females who prefer prefer thriller ) / n(females)
= 18 / 129 = 0.140
Comparing the probabilities obtained, Males prefer thriller has the highest probability, thus the strongest association.

Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65. How many dollars would he get at this rate for recycling 200 pounds of cans?
Answer:
$354
Step-by-step explanation:
first we need to find out how much 1 lb of can is then we can multiply that by 200 to get the answer.
so I divided 43 by 23.65 and got 1.81818181
i'll round that to $1.82 so that equals 1 lb of a can
multiply that by 200
the answer is $354
For recycling 200 pounds of cans, he will get $110.
What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is that Carlos saves aluminum cans to sell to the recycling center. He recently recycled 43 pounds of cans and received $23.65.
For 43 pounds, he recieved $23.65
For 1 pound, he will receive $(23.65/43)
For 200 pounds, she will receive $(23.65/43) x 200 or $110.
Therefore, for recycling 200 pounds of cans, he will get $110.

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 10 men was 37 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 16 women was also 37 minutes, but the standard deviation of the sample was 14 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women?
Answer:
We reject H0; that there is significant evidence to support that there is difference in the variation in the listening times for men and women
Step-by-step explanation:
Given that :
n1 = 10 ; s1 = 13 ; n2 = 16 ; s2 = 14 ; α = 0.1
Null : H0 : σ1² = σ2²
Alternative : H1 : σ1² ≠ σ2²
To compute the test statistic ; using the Ftest:
F-test = σ2² / σ1² = 14² / 13²
F-test = 14²/13² = 196 / 169 = 1.1597
Decision region :
Reject Null, H0 ; if
Ftest < Fcritical
F critical at:
At α/2 = 0.10/2 = 0.05
df_numerator = 16 - 1 = 15
df_denominator = 10 - 1 = 9
Using F critical calculator :
Fcritical = 3.006
1.1597 < 3.006
Since, Ftest is lesser than Fcritical, then we reject H0

Find the slope-intercept form of the equation of the line which contains the points (-2, 5) and (3, 20).
Answer:
y = 3x - 11
Step-by-step explanation:
First, use the y2-y1/x2-x1 format to find the slope: 20 - 5/3 - (-2)(Note: change 3 - (-2) to 3 + 2 to make it easier for you)
Simplify 15/5.Your slope would be 3/1 or 3.
Now use the slope-intercept format: y = mx + b(Use either the first point or second point, I chose the first)
5 = 3(-2) + b
Multiply 3 and -2, which is -6.Subtract 5 from -6: -6 - 5 = -11Your y-intercept is -11.

a number d minus 2 is less than -1 as an inequality
Answer:
(d-2) <-1
Step-by-step explanation:
The number be d. d minus 2 means (d-2).
(d-2) is less than -1.
It means,
(d-2) <-1
It is the required inequality.
So,
Adding 1 both sides.
d-2+1 <-1+1
d-1<0
or
d<1
Hence, this is the required solution.

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15
Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]
[tex]y = \frac{1}{5}x - 3[/tex]
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

If R is the midpoint of PS with PR=6x+16 and RS=-26 then find PS
Answer:
PS = 116
Step-by-step explanation:
Given:
PR = 6x + 16
RS = 12x - 26
Required:
Find PS
Solution:
Since R is the midpoint of PS, therefore,
PR = RS
6x + 16 = 12x - 26
Collect like terms
6x - 12x = -16 - 26
-6x = -42
Divide both sides by -6
x = -42/-6
x = 7
✔️PS = PR + RS (segment addition postulate)
PS = 6x + 16 + 12x - 26
Plug in the value of x
PS = 6(7) + 16 + 12(7) - 26
PS = 42 + 16 + 84 - 26
PS = 116

What is the x intercept of the graph of the inequality 2x + 3y > 12
Answer: x intercept = 6
This is the location (6,0)
===============================================================
Explanation:
I assume you're talking about the boundary line of the inequality. The boundary line equation is 2x + 3y = 12
To find the x intercept, plug in y = 0 and solve for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 12/2
x = 6
The boundary line 2x+3y = 12 crosses the x axis at x = 6.
We can say the x intercept is x = 6. This is the location (6,0).
Side note: the y intercept is y = 4, which is found by plugging in x = 0 and solving for y.

Answer:
[tex]\boxed {\boxed {\sf No \ real \ roots/ solutions }}[/tex]
Step-by-step explanation:
The value of the discriminant (b²-4ac) can tell us 3 things:
Positive value: 2 real roots Equal to 0: 1 real root Negative value: No real roots, but imaginary roots can exist.The quadratic equation given has a discriminant of -8. This value is negative, so we know that the quadratic has no real solutions.

Find the degree measure of each angle in the triangle.
Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.

bus in km/hr?
Answer:
40 km
Step-by-step explanation:
You have 2 variables: km and minutes/hour
30 minutes turned into 60 minutes(1 hour) by multiplying by 2...
So you need to do the same for km!
20km * 2 = 40km per hour
