(20 points) It has been suggested that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the
length of stay of a trip for pre- and post-retirees. A sample of 697 travelers were asked how long they stayed on a typical trip. The observed results
of the study are found below.
The expected frequencies from the data conducted to investigate the differences in the length of stay of a trip will be 221.7097, 72.471, 49.3881, and 25.7677.
How to calculate the expected frequencies?From the complete question, the expected frequencies from the data about the trip will be calculated thus:
E(240) = (379 × 413) ÷ 706
=221.7097
E(83) =(379 × 153) ÷ 706

Answer:
which is a better investment and by how muchIt's 14% p.a simple interest
Step-by-step explanation:
Simple interst:
Answer:
I = $ 649.60
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 14%/100 = 0.14 per year,
then, solving our equation
I = 2320 × 0.14 × 2 = 649.6
I = $ 649.60
The simple interest accumulated
on a principal of $ 2,320.00
at a rate of 14% per year
for 2 years is $ 649.60.
Compound interest
Answer:
A = $2,945.78
A = P + I where
P (principal) = $2,320.00
I (interest) = $625.78
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 12/100
r = 0.12 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 2,320.00(1 + 0.12/12)(12)(2)
A = 2,320.00(1 + 0.01)(24)
A = $2,945.78

If a book rests on a flat table in what direction does the normal force from the table act on the book?
Answer:
The normal force is the force that a surface makes on an object that lies on that surface.
As the book rest flat in the table, the force acting on the book will be the gravitational force. This force pulls down the book against the table, then the normal force will be opposite to this, then the direction of this force is upwards. Being more exact, the normal force always acts on the normal direction to a given surface, to find the normal of a surface, you need to find the plane of the surface, then any perpendicular line to that surface will be "normal" to the surface (and the normal direction points away from the surface) then if the book is resting on top of the table, the direction of the normal will be upwards..
Then the force that acts on the book is normal to the surface of the table,

The radius of a circular pond is increasing at a constant rate, which can be modeled by the function , where t is time in months. The area of the pond is modeled by the function . The area of the pond with respect to time can be modeled by the composition . Which function represents the area with respect to time? A. B. C. D.
Answer:
B. A(r(t)) = 25πt²
Step-by-step explanation:
Find the completed question below
The radius of a circular pond is increasing at a constant rate, which can be modeled by the function r(t) = 5t where t is time in months. The area of the pond is modeled by the function A(r) = πr². The area of the pond with respect to time can be modeled by the composition . Which function represents the area with respect to time? A. B. C. D.
Given
A(t) = πr²
r(t) = 5t
We are to evaluate the composite expression A(r(t))
A(r(t)) = A(5t)
To get A(5t), we will replace r in A(t) with 5t and simplify as shown
A(5t) = π(5t)²
A(5t) = π(25t²)
A(5t) = 25πt²
A(r(t)) = 25πt²
Hence the composite expression A(r(t)) is 25πt²

How do I do this I’m stuck and I have no idea how to do this I’m very behind and need help
Step-by-step explanation:
I don't see all the options.
I only see the options under "angles", as it seems.
anyway, the way to prove this is :
the official definition of similar triangles is :
two triangles are said to be similar if their corresponding angles are congruent (and the corresponding sides are in proportion - but that is automatically true, when all 3 angles are matching).
so, if two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. we know this, because if two angle pairs are the same, then the third pair must also be equal (remember, the sum of all angles in a triangle is always 180°). When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
now, we look at the 2 triangles.
the angles QPR and STR are congruent (the same size).
we know also the angles QRP and SRT : they are both 90° and therefore congruent.
and that means that also the third angles PQR and RST are equal and therefore congruent (due to the 180° sum rule).
so, we have all 3 pairs of angles to be congruent, and the two triangles are therefore similar.
Whats the range of the graph?
A- y= -1
B- y< -1
C- x> -1
D-x> 1
Other:________
Answer: Range is y > -1
Explanation:
The lowest point is where the open hole is. This is when y = -1. The open hole means we exclude it from the graph, so we can't reach y = -1
We can have any y value larger than -1 as part of the range. So the range is the set of y values such that y > -1
Side note: the domain is x > 1 for similar reasoning, but we're looking at the possible x values now.
Jace walked a total distance of StartFraction 5 Over 6 EndFraction of a mile to school this week. If he walked the same distance each of the 5 days, how far did he walk each day?
He walks 5/6 of a mile each day.
Multiply the distance each day by the number of days:
5/6 x 5
When multiplying a fraction by a whole number, multiply the numerator ( top number) by the whole number and leave the denominator ( bottom number as is)
5/6 x 5 = (5 x5)/6 = 25/6 now rewrite as a proper fraction:
25/6 = 4 1/6 total miles.
Answer:
4 1/6 miles over the course of 5 days

The graph shows the distance cars A and B travel.
Which statement is true about the unit rates shown in the graph?
A. The unit rate for car A is greater because the slope is greater than the slope for car B.
B. The unit rate for car B is greater because the slope is less than the slope for car A.
C. The unit rate for car A is greater because the slope is less than the slope for car B.
D. The unit rate for car B is greater because the slope is greater than the slope for car A.
Answer:
(a) The unit rate for car B is greater because the slope is greater than the slope for car A.
Step-by-step explanation:
We have been given a graph that represents the distance cars A and B travel. We are asked to choose the correct option about our given graphs.
Since slope represents the change in y-value with respect to change in per unit x value, so slope is also unit rate of the graph.
Let us find the slope of car A using points (8,5) and (0,0).
Let us find the slope of car B using points (5,8) and (0,0).
We can see that slope of car B is greater than slope of car A, therefore, option A is the correct choice.

5. Part A: Show another way to find the slope of the line that passes through the points listed in the table. Your way must be different from Avery's method.
. Part B: Justify why Avery's "divide y by x" method will not work to find the slope of every line and given an example (using a table, equation, or graph) in your justification
Answer:
The slope-intercept form
y = mx + bHere m is the slope and b is y-intercept
When b= 0
y = mxand
m = y/xIn this case Avery's method works
When b≠0
m = (y -b)/xIn this case Avery's method brings wrong outcome

L is the midpoint of MN¯¯¯¯¯¯¯, ML=2x+7 and LN=3x−3. Find ML, LN, and MN.
Answer:
[tex]ML=27\\LN=27\\MN=54[/tex]
Step-by-step explanation:
Since L is the midpoint of MN, by the definition of midpoint:
[tex]ML=LN[/tex]
We can picture the following segment:
M----------L----------N
We know that [tex]ML=2x+7[/tex] and [tex]LN=3x-3[/tex]. Since the two segments are equivalent, we can set them equal to each other:
[tex]2x+7=3x-3[/tex]
Now, let's solve for x. Subtract -7 from both sides:
[tex]2x=3x-10[/tex]
Subtract 3x from both sides:
[tex]-x=-10[/tex]
Divide both sides by -1:
[tex]x=10[/tex]
So, the value of x is 10.
With this, we can find the remaining lengths.
We know that ML is [tex]2x+7[/tex].
Substitute 10 for x. So, the length of ML is:
[tex]ML=2(10)+7=20+7=27[/tex]
We know that LN is [tex]3x-3[/tex]. So, the length of LN is:
[tex]LN=3(10)-3=30-3=27[/tex]
Finally, MN will be the combined lengths of ML and LN. So:
[tex]MN=ML+LN=27+27=54[/tex]
And we're done!
