Answer:
y = -2x + 4
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of -2 and passes through (5, -6).
We want to write the equation of the line.
There are three ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b the value of y at the y-intercept.Standard form, which is ax+by=c, where a, b, and c are free integer coefficients. Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Any of these forms will work, however let's put it into slope-intercept form as that is the most common way.
SolvingAs we are already given the slope, we can immediately plug that into the equation.
Substitute m with -2.
y = -2x + b
Now, we need to solve for b.
As the equation passes through (5, -6), we can use its values to help solve for b.
Substitute 5 as x and -6 as y.
-6 = -2(5) + b
Multiply.
-6 = -10 + b
Add 10 to both sides.
4 = b
Substitute 4 as b.
y = -2x + 4

Find the indicated probability. The age distribution of students at a community college is given below. Age (years) Number of students (f) 1109​ A student from the community college is selected at random. Find the probability that the student is at least 31. Round your answer to three decimal places.
Answer:
0.063 is the probability of at least 31 students.
Step-by-step explanation:
Solution:
Given:
The age distribution of students is given below:
Age (years) Number of students
Under 21 414
21 - 25 413
26 - 30 212
31 - 35 50
0ver 35 20
total 1109
A student from community college is selected at random.
The ratio of favorable outcomes numbers of that event is the probability of to the total number of possible outcomes in experiment.
Probability of at least 31 students:
Probability of At least 31 students = 31 or more than 31 students
P( 31 – 35) = n (31 – 35) + n (over 35) / n(T)
= 50 + 20 / 1109
= 70 / 1109
= 0.063
0.063 is the probability of at least 31 students.

Answer:20
Step-by-step explanation:
solids quiz edg 2021
The number vertices does the polyhedron have is 20.
What is Polyhedron?A polyhedron is a three-dimensional structure in geometry that has flat, polygonal faces, edges that are straight, and sharp vertices. A convex polyhedron is made up of finitely many points that are not all on the same plane and has a convex hull. Convex polyhedra include shapes like cubes and pyramids.
Using Euler formula
F + V = E + 2
As, From the figure the faces = 7 and edges = 30
12 + V = 30 + 2
12 + V = 32
V = 32- 12
V= 20

Trenton has already solved 8 math problems in 30 minutes. His math challenge book has 175 problems. He plans to work for 45 minutes per day until he finishes every problem. At this rate, how many days before he finishes all of the problems?
Answer:
It will take him 15 days before all of the math problems finish.
Step-by-step explanation:
8 ÷ 3 = 0.266666667
8 math problem ÷ 30 minutes = math problems per minutes
0.266666667 X 45 = 12
math problems per minute X 45 Minutes = math problems per day
175 ÷ 12 = 14.5833333
math problems per day ÷ math problem = days

According to the 2010 census, 4.0% of U.S. households were multigenerational (containing at least three generations: grandparents, parents, and children). A more recent study found that among 580 U.S. households surveyed, 28 were multigenerational. Does this study provide strong enough evidence to conclude that the percentage of multigenerational households has changed
Answer:
We know that at CI of 90% the new study provide evidence to claim that the porcentage of multigenerational households has not change
Step-by-step explanation:
To use Normal Distribution as an approximation of the binomial distribution
and develop a test of proportion we look at the products:
n*p and n*q in the sample
p = 28/580 p = 0,04827 then q = 0,95173
and n*p = 580*0,04827 = 27,99 > 5
n*q = 580*0,95173 = 552 > 5
Hypothesis Test:
p₀ = 4 % p₀ = 0,04
sample size n = 580
p sample proportion mean p = 0,04
Chossing a confidence Interval CI = 90 % then α = 10% α = 0,1
α/2 = 0,05 and z(score) = 1,64 z (c) = 1,64
The test is a doble tail test since the question is about difference between the study and the past census
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p ≠ p₀
To calculate z(statistics) z(s)
z(s) = ( p - p₀ ) / √ p*q/n
z(s) = ( 0,04827 - 0,04 ) * √580 / √0,04827*0,95173
z(s) = 0,00827*24,08/ √0,04594
z(s) = 0,1991/ 0,2143
z(s) = 0,929
Comparing z(s) and z(c)
z(s) < z(c) ; 0,929 < 1,64
Therefore at CI 90% we accept H₀ since z(s) is in the acceptance region

A card is drawn at random from a standard 52-card deck. Find the probability that the card is an ace or not a club.
Answer:
0.7692077
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of aces in a standard deck = 4
Number of clubs in a standard deck = 13
Probability = required outcome / Total possible outcomes
P(ace) = 4 / 52 = 0.0769
P(club) = 13 / 52 = 1/4 = 0.25
P(not club) = 1 - p(club) = 1 - 0.25 = 0.75
P(ace and not club) = 3/52 = 0.0576923
P(ace or not club) = p(ace) + p(not club) - p(ace and not club
= 0.0769 + 0.75 - 0.0576923
= 0.7692077

Answer:
264 minutes OR 4.4 hours OR 4 hours and 24 minutes (all the same)

You commute to school my walking and by riding the bus. The graph represents your commute
A. Describe your commute in words
B. Caculate the slopes of the different parts of the graph
Answer:
A. You commute to school by walking 0.5 mile to the bus stop in 10 minutes, then waiting 4 minutes for the bus, then riding the bus for 2 miles in 4 minutes.
B. The slope of the first part (walking) is 0.05
The slope of the second part (waiting) is 0.
The slope of the third part (riding the bus) is 0.5
Step-by-step explanation:
From the graph, you can see that a distance of 0.5 mile was covered in the first 10 minutes of commuting. This means that you walked 0.5 mile for 10 minutes to where you want to wait to board a bus.
Then you spent another 4 minutes in waiting for the bus (14 - 10 = 10), while remaining on the same location. No distance was covered during this time spent, as we can see, the slope is horizontal.
You later got a bus, which travelled, 2 miles (2.5 - 0.5 = 2 miles), from where you boarded the bus to your final destination for a period of 4 minutes (18 - 14 = 4 mins).
In simple terms you can describe your commute as follows:
You commute to school by walking 0.5 mile to the bus stop in 10 minutes, then waiting 4 minutes for the bus, then riding the bus for 2 miles in 4 minutes.
B. Slope = rise/run
Therefore:
The slope of the first part (walking) is [tex] \frac{0.5}{10} = 0.05 [/tex].
The slope of the second part (waiting) is 0. (slope of horizontal line is always 0)
The slope of the third part (riding the bus) is [tex] \frac{2}{4} = 0.5 [/tex].

Consider the profits of two different clothing factories can be modeled as shown, where s is the number of shirts produced at each factory.
Factory A : [tex]-0.06s^2+43s-1600[/tex]
Factory B : [tex]-0.04s^2+32s-1500[/tex]
To find:
The polynomial that represents the difference in the profits at the two plants.
Solution:
Let,
Factory A : [tex]P_1=-0.06s^2+43s-1600[/tex]
Factory B : [tex]P_2=-0.04s^2+32s-1500[/tex]
Difference in the profits at the two plants is
[tex]Difference= P_1-P_2[/tex]
[tex]Difference= -0.06s^2+43s-1600-(-0.04s^2+32s-1500)[/tex]
[tex]Difference= -0.06s^2+43s-1600+0.04s^2-32s+1500[/tex]
[tex]Difference= (-0.06s^2+0.04s^2)+(43s-32s)+(-1600+1500)[/tex]
[tex]Difference= -0.02s^2+11s-100[/tex]
Therefore, the required expression is [tex]-0.02s^2+11s-100[/tex].
