Seven people, named Anna, Bob, Chandra, Darlene, Ed, Frank, and Gina, will be interviewed for a job. The interviewer will choose two at random to interview on the first day. What is the probability that Anna is interviewed first, and Darlene is interviewed second?
Answers
Answer:
0.0238
Step-by-step explanation:
Total number of persons to be chosen from = 7
If each person has an equal probability of being selected ;
Number of persons to be selected = 2
Probability = required outcome / Total possible outcomes
P(Anna first) = 1 / 7
Recall; this is a selection without replacement ;
P(Darlene second) = 1 / 6
1/7 * 1/ 6 = 1 / 42 = 0.0238

Answer:
x = 2.5
Step-by-step explanation:
Because the triangles are similar, you can divide the sides and equal the results:
24/6 = 10/x
24•x/6 = 10
24•x = 10•6
24•x = 60
x = 60/24
x = 2.5
Answer:
x = 2.5 km
Step-by-step explanation:
In similarity triangles, corresponding sides are in same ratio.
[tex]\frac{DF}{BC}=\frac{EF}{AC}\\\\\frac{10}{24}=\frac{x}{6}\\\\\frac{10}{24}*6=x\\\\x=\frac{10}{4}\\\\x=\frac{5}{2}\\\\x= 2.5[/tex]

y = 3
x =?
The value of x can be obtained as follow:
y = √(–2x + 7)
3 = √(–2x + 7)
Take the square of both side
3² = –2x + 7
9 = –2x + 7
Collect like terms

Answer:
Values of y in order: 0, 2, 4, 6
Step-by-step explanation:
Hi there!
In the table, the first value of x is -2. To find the value of y for this row of the table, we can use the given equation [tex]y=2x+4[/tex].
[tex]y=2x+4[/tex]
Plug in -2 as the value of x
[tex]y=2(-2)+4\\y=-4+4\\y=0[/tex]
Therefore, y is 0 when x is -2. (In the table, in the row where x is -2, y would be 0.)
We repeat this process for the rest of the values in the table.
When x=-1:
[tex]y=2(-1)+4\\y=-2+4\\y=2[/tex]
When x=0:
[tex]y=2(0)+4\\y=0+4\\y=4[/tex]
When x=1:
[tex]y=2(1)+4\\y=2+4\\y=6[/tex]

Answer:
3x - y +5=0
Step-by-step explanation:
Slope:-
=> m = 2-8/-1-1 = -6/-2
=> m = 3
Using point slope form :-
=> y - 2 = 3 ( x - (-1))
=> y - 2 = 3x + 3
=> 3x - y +5 = 0
Answer:
y=3x+5
Step-by-step explanation:
first find the gradient
m=y2-y1/x2-x1
from the coordinates you are given x one is -1,x two is1,y one is 2,y two is 8
8-2/1-(-1)
=3
therefore the gradient is 3
after finding the gradient use the equation
y-y1=m(x-x1)
substitute x1,y1 and the gradient..y and x are constant
y-2=3(x-(-1))
y-2=3x+3
y=3x+3+2
y=3x+5

Answers
Hello,
the line passing through (5,2) and (1,0) has for equation:
y-0=(x-1)*(-2)/(-4) or y=x/2-0.5
if y= 5 then 5=x/2-0.5 ==> 5.5=x/2 ==> x=11
Answer C
Answer:
C
Step-by-step explanation:
Since the points lie on the same line then the slope between consecutive points will be the same.
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 2) and (x₂, y₂ ) = (1, 0)
m = [tex]\frac{0-2}{1-5}[/tex] = [tex]\frac{-2}{-4}[/tex] = [tex]\frac{1}{2}[/tex]
Calculate the slope again and equate to [tex]\frac{1}{2}[/tex]
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (a, 5)
m = [tex]\frac{5-0}{a-1}[/tex] = [tex]\frac{1}{2}[/tex] , so
[tex]\frac{5}{a-1}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
a - 1 = 10 ( add 1 to both sides )
a = 11

Therefore, f(c) = 3c+5
OPTION B is the correct answer
Answer:
(B) f(c) = 3c + 5
Step-by-step explanation:
Since variable "c" is the independent variable, that means in terms of y = mx + b, c would be the variable "x".
So that means to rewrite 6c = 2p - 10, you would solve for p, because p would equal y in the formula.
Use basic algebra to solve for p:
6c = 2p - 10
6c + 10 = 2p
3c + 5 = p
p = 3c + 5 or f(c) = 3c + 5

Dado que Augusto nació en Roma el 23 de septiembre del año 63 a. C y fue el primer emperador romano que gobernó entre el año 27 a. C y 14 d. C considerándose como el emperador con el reinado más prolongado de la historia, y después de su muerte el 19 de agosto del año 14 d. C el senado romano lo inmortalizó glorificando su legado, por esta razón, varios de los emperadores que lo siguieron adoptaron sus nombres, para determinar cuántos años cumplidos vivió Augusto se debe realizar el siguiente cálculo:
Nacimiento: 23/09/63 AC
Primer año: 23/09/62 AC
Tercer año: 23/09/60 AC
Sesenta y dos años: 23/09/01 AC
Sesenta y tres años: 23/09/01 DC

In AABC, point D is the centroid, and AD= 12. Find AG
Answers
Answer:
AG = 18
Step-by-step explanation:
The relationship of the segments created is one is 1/3 (shorter) and the other (longer) is 2/3 of the total length.
Lets make x represent AG.
So, 2/3 of x is 12
or
[tex]\frac{2}{3}[/tex]x = 12
Multiply both sides by the reciprocal of [tex]\frac{2}{3}[/tex] , which is [tex]\frac{3}{2}[/tex].
( [tex]\frac{3}{2}[/tex]) [tex]\frac{2}{3}[/tex]x = 12 ([tex]\frac{3}{2}[/tex]) (x is left alone, the fractions = 1 when multiplied)
x = 12 ([tex]\frac{3}{2}[/tex]) ( 12 times 3 = 36, divided by 2 = 18)
x = 18

Step-by-step explanation:
Given the table :
Number of sodas 24
28
32
36
Total Cost ($)
18
21
24
27
The rate of change :
Rate of change = Rise / Run
Rise = y2 - y1 ; Run = x2 - x1
From the table :
Take number of sodas as X - axis
Total cost as Y - axis
Taking the points :
(24, 18) ;(36, 27)
x1 = 24 ; x2 = 36
y1 = 18 ; y2 = 27
Rise = (y2 - y1) = (27 - 18) = 9
Run = (x2 - x1) = (36 - 24) = 12
Rate of change = 9 / 12 = 0.75
