Ryan has 7 black pairs of socks, 3 pair of brown socks, and 8 white pairs of socks in his wardrobe. He randomly picks one pair. Find P(NOT Black) in fraction form
Answer:
Black socks pairs = 7
Brown socks pairs = 3
White socks pairs = 8
P(not black) = ?
First, you need to add the brown & white socks pairs,
[tex]3 + 8 = 11[/tex]
Then you need to add the total number of socks pairs,
[tex]7 + 3 + 8 \\ = 7 + 11 \\ = 18[/tex]
P(not black)
[tex] = \frac{11}{18} [/tex]
Step-by-step explanation:
solution given:
total pair of socks[S]=(7+3+8)=18
total pair of black socks[B]=7
total pair of brown socks [C]=3
total pair of white socks[W]=8
total no of orange marbles[O]=2
now
the P( not black) =?
we have
P( not black) =1-[tex] \frac{n[B]}{n[S]} [/tex]
P( not black) =1-[tex] \frac{7}{18} [/tex]
P( not black) =[tex] \frac{18-7}{18} [/tex]
P( not black) =[tex] \frac{11}{18} [/tex]
so 11/18 is a required probabilty.
The population P, of Caribou in the Yukon is modeled by P=6x^2-120x+1250 where X is the number of years from today. After how many years with the Caribou population route 21,000 round to one decimal place
Answer:
It will take approximately 68.2 years for the Caribou population to reach 21,000.
Step-by-step explanation:
The population P of Caribou in the Yukon is modeled by P=6x²-120x+1250 where x is the number of years from today.
If the population P of Caribou in the Yukon is 21000, then, replacing you get:
21000= 6x²-120x+1250
So:
0= 6x²-120x+1250 -21000
0= 6x²-120x - 19750
This is a quadratic function of the form: 0= ax²+ bx +c, where: a=6, b= -120 and c=-19750
To solve a quadratic function and determine the value of x you can use the expression:
[tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]
Replacing the values of a, b and c and solving you get:
[tex]x1,x2=\frac{-(-120)+-\sqrt{(-120)^{2}-4*6*(-19750) } }{2*6}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{14400+474000 } }{12}[/tex]
[tex]x1,x2=\frac{120+-\sqrt{488400 } }{12}[/tex]
[tex]x1,x2=\frac{120+-698.86 }{12}[/tex]
So:
[tex]x1=\frac{120+698.86 }{12}[/tex]
x1= 68.24 ≅ 68.2
and
[tex]x2=\frac{120-698.86 }{12}[/tex]
x2= -48. 24 ≅ -48.2
As time cannot be negative, it will take approximately 68.2 years for the Caribou population to reach 21,000.

Answer:
<AEB = 51.2
Step-by-step explanation:
Remark
A straight line has a degree value of 180. There are 3 angles. One of them is 90. The other two must add to 90
Equation
2.7x + 8 + 3.8x - 22 = 90 combine like terms on the left.
6.5x - 14 = 90 add 14 to both sides
6.5x = 90 + 14
6.5x = 104 Divide by 6.5
x = 104/6.5
x = 16
<AEB = 2.7*16 + 8
<AEB = 51.2

the ovals has an area of x – 5 square inches.
Answer:
4x^2 - 14x + 19
Step-by-step explanation:
A = LW
A = (2x-3) (2x-3)
4x^2 - 6x - 6x + 9
Combine like terms:
4x^2 - 12x + 9
-2(x - 5) (for both ovals)

7) The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. If the height of the prism is
14 feet, find its volume.
mine the volume if its length is 18 inches
Given:
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet.
Height of the prism is 14 feet.
To find:
The volume of the triangular prism.
Solution:
The area of a triangle is:
[tex]Area=\dfrac{1}{2}\times b\times h[/tex]
Where, b is base and h is height of the triangle.
The base of a prism is a right triangle with legs measuring 16 feet and 4 feet. It means the base of the triangle is 16 feet and height is 4 feet. So, the area of the base of the prism is:
[tex]B=\dfrac{1}{2}\times 16\times 4[/tex]
[tex]B=32[/tex]
Now, the volume of a triangular prism is:
[tex]V=Bh[/tex]
Where, B is base area and h is the height.
Putting [tex]B=32,h=14[/tex] in the above formula, we get
[tex]V=32\times 14[/tex]
[tex]V=448[/tex]
Therefore, the volume of the triangular prism is 448 cubic feet.

Brandon is analyzing the profits from two of his restaurant locations. The first location showed a profit of $3,000 in the first week of the year but
has a showed a steady decrease in profits of 1.5% each week since then.
His second location showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since
then.
Which system of equations can Brandon use to determine the number of weeks, x, until the profits, y, from the two locations are the same?
ОВ.
OA y = -3,000(0.985)
y = 1,500(1.012)
y = 3,000(1.015)"
y = 1,500(1.012)"
OC.
y = -3,000(1.015)"
y = 1,500(1.012)
y = 3,000(0.985)
y = 1,500(1.012)"
OD.
Answer:
y=3,000(0.985)^x
y=1,500(1.012)^x
Step-by-step explanation:
System of equations Brandon can use for two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]
What is profit and loss percentage?Profit and loss percentage are used to refer to the amount of profit or loss that has been incurred in terms of percentage.
According to question
Brandon is analyzing the profits from two of his restaurant locations.
where
x = number of week
y = the profit
1st restaurant : showed a profit of $3,000 in the first week of the year but
has a showed a steady decrease in profits of 1.5% each week since then
So in equation we can write it as
y= [tex]3000(1 - 0.015)^{x\\}[/tex]
y= 3000[tex](0.985)^{x}[/tex]
2nd restaurant : showed a profit of $1,500 in the first week of the year and has showed a steady increase in profits of 1.2% each week since then.
So in equation we can write it as
y = [tex]1500(1+0.012)^{x}[/tex]
y =[tex]1500(1.012)^{x}[/tex]
Hence, system of equations can Brandon use to determine the x and y form the two location are y= 3000[tex](0.985)^{x}[/tex] and y =[tex]1500(1.012)^{x}[/tex]

Answer:
B, C, E
Step-by-step explanation:
When the central angles are congruent, the corresponding triangles are congruent:
ΔJHK ≅ ΔLHM . . . . selection E
and the base chords are congruent:
ML ≅ JK . . . . selection B
The subtended arcs are also congruent, so adding arc LK to each will result in congruent arc measures:
arc MLK ≅ arc LKJ . . . . selection C
Form and solve an equation for x.
6x +40
Х
3x + 100
Answer:
x = 22
Step-by-step explanation:
The sum of the angles round a point is 360°
Sum the given angles and equate to 360
x + 6x + 40 + 3x + 100 = 360
10x + 140 = 360 ( subtract 140 from both sides )
10x = 220 ( divide both sides by 10 )
x = 22

Miriam is going to the county fair. Each ride ticket costs $2 and admission costs $7. Miriam has $25 to spend at the fair.
Answer:
9
Step-by-step explanation:
Given data
Ride ticket= $2
Admission= $7
Amount= $25
We want to find the greatest number of rides
let the number of rides be x
The expression to describe how she spends the amount is given as
y=7+2x
for y= 25, let us find x
25= 7+2x
25-7= 2x
18=3x
x= 18/2
x= 9
Hence the number of rides is 9
