Monte recorded the gas mileage, in miles per hour, of ten different cars he is considering buying: 34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
What is the median?
Answer:
29.4
Step-by-step explanation:
42+34=76
76+31=107
107+30+30=167
167+29=196
196+28=224
224+27=251
251+24=275
275+19=294
there are 10 cars that he wants
294/10=29.4
The median of the given data set is 29.5.
What are the mode and median?Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.
For example;
Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.
As per the given mileage set,
34, 27, 30, 24, 28, 31, 42, 30, 29, and 19.
Write the above set in increasing order as
19,24,27,28,29,30,30,31,34,42
The median will be the middle value, since there is an even number so median will be as,
Median = (5th value + 6th value)/2
Median = (29 + 30)/2 = 29.5
Hence "The median of the given data set is 29.5".

(iii) A relation between a and b such that point (a,b) isequidistant from the points (8,3) and (2,7)
Answer:
7.21 units
Step-by-step explanation:
GIven data
Point 1= (8,3)
x1= 8
y1= 3
Point 2= (2,7)
x2= 2
y2= 7
The expression for the distance between two points is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-8)²+(7-3)²)
d=√((-6)²+(4)²)
d=√36+16
d=√52
d= 7.21
Hence the distance between the points is 7.21 units

is (x-4) a factor of 2x^4-9x^3-20x^2+147x-180? find out by using the factor theorem.
Answer: (x-4) is not a factor of the given polynomial.
===================================================
Explanation:
Rule: If (x-k) is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem. We can take this in reverse to say that if p(k) = 0, then (x-k) must be a factor of p(x).
In this case, we have k = 4 and we can find that:
p(x) = 2x^4-9x^3-20x^2+147x-180
p(4) = 2(4)^4-9(4)^3-20(4)^2+147(4)-180
p(4) = 24
The result we get is not zero, so that means (x-4) is not a factor of p(x).

3) Josie's collection of 39 coins includes twice as many nickels than quarters. If
the sum of the nickels and quarters is $4.55, How many quarters does Josie
have in her collection?
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P′Q′R′ has vertices P′(1, −2), Q′(0, 3), and R′(−1, 0).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answer:
P' = 1/3 P
reflection in the y-axis just changes the sign of all the x-values.
Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P
It is, however, similar to P.
Answer:
P' = 1/3 P
Step-by-step explanation:
Reflection in the y-axis just changes the sign of all the x-values. Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P . It is, however, similar to P.

On a BWIA flight, 2/3 of the
passengers are from Trinidad.
If there are 189 passengers
altogether, how many were
from Trinidad?
Answer:
126 passengers from Trinidad.
Step-by-step explanation:
Given that,
On a BWIA flight, 2/3 of the passengers are from Trinidad.
Total passengers = 189
We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,
[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]

your cell phone plan is by the minute. each minute of use cost $0.10. create a relation that represents the amount spent, A, per minute, m, of call time. Then, use the relation to find the amount spent if you talk 65 minutes.
Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
Thus, talking 65 minutes, $ 6.50 must be paid.
