Answer:
You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.
The probability of selecting a red marble the first time is 1313.
(This is because 4 out of 12 marbles are red and412412 reduces to 1313.
The probability of selecting a red marble the second time is 1313.
The marble selections are independent and you can multiply the two probabilities to get the following:
probability of getting 2 reds = (13)2(13)2
=19=19.
So the probability of getting two reds is 1919.
ez pts someebody help find the equation axis of symmetry of y=-2(x-3)^2 +4
Answer:
x = 3Step-by-step explanation:
Given function:
y= -2(x-3)² +4Vertex form:
y = a(x − h)² + kAxis of symmetry is the line parallel to y-axis and passes through vertex. The x-coordinate of the vertex is determined by the value of h in the above equation.
We have h = 3 as per given equation for the function.
Axis of symmetry is the line x = 3
The point-slope form of the equation of the line that passes through (44, -3) and (12, 1) is y-1 = (x - 12). What is
the standard form of the equation for this line?
Answer:
-y+(x-12)=-1

An angle measures 148° more than the measure of its supplementary angle. What is the measure of each angle? AND DONT PLAGERISE!!!
Answer:
Step-by-step explanation:
Supplementary angles add up to 180°.
“θ is 148° more than its supplement”
Supplement of θ = 180°-θ
θ = (180°-θ) + 148°
2θ = 328°
θ = 164°
Supplement of θ = 180°-164° = 16°

Answer:
s = 17t = 5Step-by-step explanation:
The midpoint formula is useful here. For midpoint M, we have ...
M = (C + D)/2
2M = C + D
2(10, 10) = (15, s) +(t, 3)
(20, 20) = (15+t, s+3)
t = 20 -15 = 5
s = 20 -3 = 17
__
Check
(C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

Given the figure as marked. What is x?
Answer:
6
Step-by-step explanation:
Using the similarity theorem f the triangle
(4+6)/x+9 = 4/x
10/x+9 = 4/x
Cross multiply
10x =4(x+9)
10x = 4x+36
10x-4x = 36
6x = 36
x = 6
Hence the value of x is 6

MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet

Bob and Sue are meeting on a stairway. Bob is at the top and Sue is at the bottom. There are 9 steps
from bottom to top. Bob can skip a step each time since he is going down, Sue will not skip any steps. On
which step will they meet.
Answer:
Bob is at the top, so he starts at step 9.
Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)
Sue climbs from one step on one step.
Then she if she climbs n times, she will be at the step number:
S(n) = 0 + 1*n
And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:
B(n) = 9 - 2*n
We want to see when they meet, then we need to solve:
S(n) = B(n)
1*n = 9 - 2*n
1*n + 2*n = 9
3*n = 9
n = 9/3 = 3
n = 3.
This means that they meet a the step:
S(3) = 3*1 = 3
B(3) = 9 - 2*3 = 9 - 6 = 3
They meet at the third steep.
In a team, the ratio of attackers : defenders is 11:7.
Given that there are 36 players in the squad, how many more attackers are there than defenders?
fast answers pls
Answer:
8 more attackers than defenders
Step-by-step explanation:
36÷18=2
2x11=22
2x7=14
Answer:
8
Step-by-step explanation:
sum the parts of the ratio, 11 + 7 = 18 parts
Divide the number of players by 18 to find the value of one part of the ratio
36 ÷ 18 = 2 players ← value of 1 part of the ratio, then
11 parts = 11 × 2 = 22 ← number of attackers
7 parts = 7 × 2 = 14 ← number of defenders
22 - 14 = 8
There are 8 more attackers than defenders

Leah has just inherited $12,000. She wants to invest the money so that she can increase the value of
her inheritance. What are some of the ways she can do this?
1. Leah wants to invest the $12,000 in an account that pays 4.5% annual interest.
a. Write equations for the amount A(t) that will be in the account after t years, if the interest is
compounded continuously, daily, and monthly. Then, find the amount after 10 years, rounded
to the nearest cent, for each method of compounding. Complete the table
When interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
If the interest compounded continuously:
P = $12000, r = 4.5% = 0.045%
[tex]\rm A(t) =12000(e)^{0.045t}[/tex]
When t = 10 years, plug this value in the above expression and calculating, we get;
A(10) = $18819.75
When interest compounded daily:
[tex]\rm A(t) = 12000(1+\dfrac{0.045}{365})^{365t}[/tex]
Plug t = 10 years:
We get;
A(10) = $18819.22
Similarly,
If interest is compounded monthly:
n = 12 and t =10, we get:
A(10) = $18803.91
Thus, when interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

laura has 160 pounds of green beans at her vegetable stand. she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?
Answer:
18.75%
Step-by-step explanation:
Green beans = 160 pounds
Amount sold in 1 hour = 10 pounds
Amount sold in 3 hours = 3x10= 30 pounds
Decrease in 3 hours = 30 pounds
% decrease = (30/160) x 100
=300/16
=75/4
=18.75%
