The five-number summary are as follows:
Minimum = 58Lower quartile(Q₁) = 67Median = 79Upper quartile(Q₃) = 82Maximum = 87Interquartile range = 15How to solve for five-number summary?The five-number summary is a set descriptive statistics which consist of the minimum, maximum, median, upper quartile, and lower quartile of a data distribution.
Therefore,
Given:
58, 60, 65, 67, 68, 72, 79, 79, 80, 81, 82, 86, 86, 87
Therefore,
Minimum = 58
Lower quartile(Q₁) = 67
Median = 79 + 79 / 2 = 79
Upper quartile(Q₃) = 82
Maximum = 87
Interquartile range = Q₃ - Q₁ = 82 - 67 = 15

19683
Exponentiation: (-3) ^ 5 = -243
= -1/
19683
* (-243) = -1 · (-243)/
19683 · 1

The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 38 minutes of calls is $ 25.06, and the remaining credit after 69 minutes of calls is $21.03. What is the remaining credit after 80 minutes of calls?
Answer: $19.6
Step-by-step explanation:
Linear function: f(x)=mx+c
, where m= rate of change in f(x) with respect to x.
c = Initial value.
Let c = Initial value of card , m= Charge per minute
x= Number of minutes calling time.
Then, 25.06= 38m+c (i)
21.03=69m+c (ii)
Eliminate (ii) from (i)
[tex]4.03=-31m\\\\\Rightarrow\ m=\dfrac{4.03}{-31}\\\\\Rightarrow\ m=-0.13[/tex]
Put m in (i) , we get
[tex]25.06= 38(-0.13)+c\\\\\Rightarrow\ 25.06=-4.94+c\\\\\Rightarrow\ c=25.06+4.94\\\\\Rightarrow\ c=30[/tex]
i.e. f(x)=-0.13x+30
if x=80 then
f(80)= -0.13(80)+30
=-10.4+30
=19.6
Hence, the remaining credit after 80 minutes of calls = $19.6

Answer:
7(2m−3n)14m−21n
Step-by-step explanation:
The following pairs are equivalent
7(2m - 3n)
14m - 21n
If you solve 7(2m - 3n)
So
7(2m) - 7(3n)
14m - 21n
So according to the given options, the option c is correct as this pairs is to be considered as equivalent

Suppose that y varies directly with x and inversely with z. If y = 63 when x =
27 and z = 3, find the constant of proportionality.
Answer:
constant of proportionality = 7
Step-by-step explanation:
Let k = constant of proportionality
If y varies directly with x and inversely with z, then [tex]\frac{yz}{x} = k[/tex]
Substitute the values given into the equation and you get [tex]\frac{(63)(3)}{27} = 7 = k[/tex]

ZABC is a right angle which is bisected by
BD.
mZDBC = [?]°
The Measure of <DBC is 45 degree.
What is Line Bisector?When anything is divided into two equal or congruent portions, usually by a line, it is said to have been bisected in geometry. The line is then referred to as the bisector. Segment bisectors and angle bisectors are the sorts of bisectors that are most frequently taken into consideration.
Given:
<ABC = 90 degree
As, BD is bisector for < ABC.
Then, the bisector divides the angle <ABC in two equal parts.
So, <ABC = 2< ABD = 2<BDC
<DBC = 1/2 <ABC
<DBC= 45 degree

Rewrite the equation y – 4x = –9 in slope-intercept form. simple explanation and proof
Answer:
y=4x-9
Step-by-step explanation:
add 4x to both sides to isolate y
Answer:
The slope-intercept form of this equation would be y = 4x - 9.
(For explanation look down below)
Step-by-step explanation:
Slope-intercept form would be an equation that would look like...
y = mx + b
Where m is the slope and b is the intercept. From this form, we can understand that all we need to do is rearange the formula in a way that positive y would be on its left side. And so we get...
y - 4x = - 9
y - 4x + 4x = - 9 + 4x
y = 4x - 9
