A box contains 95 pink rubber bands and 90 brown rubber bands. You select a rubber band at random from the box. Find each probability. Write the probability as a fraction in simplest form.
Find the theoretical probability of selecting a pink rubber band.
Answer:A. The theoretical probability for pink is 95/185 or about 51.35%
B. The theoretical probability for brown is 90/185 or about 47.82%.
C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.
Pink 36/69 = 52.17%
Brown 33/69 = 47.82%

A laptop computer is purchased for $2000. After each year, the resale value decreases by 25%. What will the resale value be after years?
Use the calculator provided and round your answer to the nearest dollar.
$[]
Answer:
2000? ... assume $2000
Resale Value = $2000*(1 - 0.25)t/yr
where: t = number of year after purchase
at t = 3 yr
Resale Value = $2000*(1 - 0.25)3 = $843.75
checking: at t = 0 $2000 (purchase price)
at t = 1 yr $2000 - 0.25*$2000 = $2000 - $500 = $1500
at t = 2 yr $1500 - 0.25*$1500 = $1500 - $375 = $1125
at t = 3 yr $1125 - 0.25*$1125 = $1125 - $281.25 = $843.75
The solid below was made by cutting a cone-shaped hole out of a cylinder. The surface area of the resulting composite solid is square cm. Write your answer in terms of pi.
*see attachement below for the diagram
Answer:
(252π + 20) cm²
Step-by-step explanation:
The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)
✔️Curved surface area of cylinder = 2πrh
r = ½(12) = 6 cm
h = 18 cm
C.S.A = 2*π*6*18 = 216π cm²
✔️Area of 1 base = πr²
r = ½(12) = 6 cm
Area = π*6²
Area = 36π
✔️Slant height of the cone = 10 cm
✅The surface area of the resulting solid = 216π + 36π + 2(10)
= (252π + 20) cm²

A soccer ball is kicked upward from the ground with a speed of 96 feet per second. Its height h, in feet, after t seconds is given by the equation h(t) = -16² +96t.
HCL many seconds will it take the soccer ball to reach its maximum height?
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
Seconds to attain maximum height
The maximum of a quadratic function [tex]y = ax^2 + bx + c[/tex] is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
So, we have:
[tex]t = -\frac{b}{2a}[/tex]
Where:
[tex]a = -16[/tex] and [tex]b = 96[/tex]
So:
[tex]t = -\frac{96}{2 * -16}[/tex]
[tex]t = -\frac{96}{-32}[/tex]
Cancel out negatives
[tex]t = \frac{96}{32}[/tex]
[tex]t = 3[/tex]

Solve for a and b in the following circles:
B)
a а
b
82°
Answer:
a 41
when the line touch the circle you have to take the half of it
for b its equal 144
the full circle degree is 360
so we can say the 82+2x=360
because the two lines in the circle equal each other so its means tha the Piece of the circle in the left is equal b too
hopefully its helpful and sorry because of my engilish

All of the letters of MISSISSIPPI are put in a bag. What is the probability of selecting an M and then after not replacing the letter, selecting a P?
Answer:
2/110
Step-by-step explanation:
Picking the letter M is 1/11 because there is 1 letter M in the 11 letters of the word.
Selecting a P is 2/10 because there are 2 letter P's in the 10 letters( Letter M was taken out)
Multiply the 2 fractions
1/11 x 2/10 = 2/110

y=180-138
y=42
Answer:
Step-by-step explanation:
In the lower triangle, the top angle is also 90 degrees, so just add 90 +48 = 138 and subtract from 180. Y= 42 degrees.

Type the correct answer in each box.
Consider circle O, where mBD =70° and mCA = 170°
m∠BPD: ____°.
mBC + mAD = ____°.
Answer:
m∠BPD: 120°
mBC + mAD =120°
Step-by-step explanation:
A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
Given:
mBD =70°
mCA = 170°
So,
m∠BPD= 1/2( (m∠BD + m∠CA))
=1/2(170+70)
=1/2*240
=120
and,
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°

What is the approximate circumference of the coin? Use 3.14 as an estimate for it.
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm
Answer:
66mm
Step-by-step explanation:
A diagram of a coin is shown.
Radius = 10.5 mm
The approximate circumference of the coin is calculated using the formula
2πr
Use 3.14 as an estimate for it.
r = 10.5mm
Hence:
2 × 3.14 × 10.5
= 65.94
Approximately = 66mm
O A 21 mm
O B. 33 mm
O c. 66 mm
O D. 84 mm
Noah buys 3 packages of pens each package has four blue pens and two black pens which equation can be used to find p
Answer:
p = 3*[ 4p+ 2p]
Step-by-step explanation:
Total number of pens = 3 times [ 4 blue pens + 2 black pens]
If we denote the total number of pens by p then the equation becomes
p = 3*[ 4.blue + 2black]
p = 12p+6p
p = 18p
There are total 18 pens out of which 12 pens are blue and 6 pens are black.

Is
X 10 11 12
Y 18 18.6 19.2 proportional or non proportional
Given:
The table of values.
To find:
Whether the given table is a proportional or non proportional relation.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
Where, k is the constant of proportionality.
Find the value of k for each ordered pairs in table. If the value of k is constant, then the relation is proportional.
The ordered pairs from the table are (10,18), (11, 18.6), (12,19.2). The values of k for each ordered pair is:
[tex]\dfrac{18}{10}=1.8[/tex]
[tex]\dfrac{18.6}{11}\approx 1.69[/tex]
[tex]\dfrac{19.2}{12}=1.6[/tex]
Since the value of k is not constant, therefore the given table represents a non proportional relationship.
Find the value of y.
