Which events are independent? Select three options.
Roll a number cube, and then roll the same number cube again.
Flip a coin, and then flip the coin a second time.
Remove a card from a deck, and then remove a second card.
Draw a card from a deck, replace it, and then draw a second card.
Take a marble out of a bag, and then take a second marble out of the bag.
Answer: The first, second, and fourth.
Step-by-step explanation:
1). When you roll a cube twice, the number you get on the first roll doesn’t impact the second. As a result, it’s independent.
2). When you flip a coin twice, what you get on the first flip doesn’t impact what you get on the second. As a result, it’s independent.
3). When you remove a card from a deck, then remove a second one WITHOUT replacing the first, the first card impacts the second draw. For example, when I draw the first card, my chances of drawing a two are 1/13. If I draw a two the first time, my chances of drawing a two the second time are 1/17 (3/51. The total is fifty-one since one card is missing). Since the first draw impacted the probability of the second, the events are NOT independent.
4). When you remove a card, replace it, then draw again, your chances of drawing the same card doesn’t change. For example, my odds of drawing a three are 1/13 (or 4/52). If I draw a three the first time, then put it back and draw again, my odds are still 1/13 because I put the card back in the deck. As a result, the event is independent.
5). If I take a marble from a bag, and then take a second marble, the first draw impacts the second. For example, if a bag has three blue marbles and three green marbles, my chances of getting a blue marble the first time are 1/2 (or 3/6). If I get a blue marble and choose again, WITHOUT replacing it, my chances of choosing another blue marble are 2/5 (since one marble is missing). Since the first draw impacting the probability of the second, the events are NOT independent.

Answer:
1. -20 is the y intercept
2. 2x+4y=16
2x/2+4y/2=16/2
x+2y=8
x-x+2y=8-x
2y=-x+8
2y/2=-x/2+8/2
y=-x/2+4
4 is the y intercept
3. 2y+3x=7
2y+3x-3x=7-3x
2y=-3x+7
2y/2=-3x/2+7/2
y=-3
x/2+3.5
3.5 is the Y intercept
4. -3 is the y intercept
Step-by-step explanation:
Question 1:
y = -5x - 20
It is already in slope-intercept form, therefore the y-intercept is -20.
When y = 0, -5x - 20 = 0, x = -4.
Hence the x-intercept is -4.
Question 2:
2x + 4y = 16
When x = 0, 2(0) + 4y = 16, 4y = 16, y = 4.
The y-intercept is 4.
When y = 0, 2x + 4(0) = 16, 2x = 16, x = 8.
Hence the x-intercept is 8.
Question 3:
2y + 3x = 7
When x = 0, 2y + 3(0) = 7, 2y = 7, y = 3.5.
The y-intercept is 3.5.
When y = 0, 2(0) + 3x = 7, 3x = 7, x = 7/3.
Hence the x-intercept is 7/3.
Question 4:
It is ambiguous as the line marks on both of the axis are not labelled. However we assume each space is 1 unit.
Reading off the graph,
we have x-intercept is 3 and y-intercept is -3.
Which expression is equivalent to -12?
Answer:
the last one
Step-by-step explanation:
-8/3 * -3/8 = 1, so you have -12*1 there.
a bar of steel is 340cm long issa cuts two 55cm lengths of the bar he then cuts the rest of the bar into as many 40cm lengths as possible work out how many 40cm lengths of bar issa cuts
Answer:
the number of 40cm lengths cut is 5.75 pieces
Step-by-step explanation:
The number of 40cm lengths cut is shown below:
= (Length of steel bar - two lengths) ÷ (length)
= (340 cm - 55 cm - 55cm) ÷ (40 cm)
= 230 cm ÷ 40 cm
= 5.75 pieces
Hence, the number of 40cm lengths cut is 5.75 pieces
We simply applied the above formula so that the correct unit could come

Given z1 = 2 + sqrt 3i and z2 = 1 – sqrt 3i, what is the sum of z1 and z2?
Answer:
b
Step-by-step explanation:
took test
The sum of z₁ and z₂ is 3.
What are complex numbers?The sum of a real number and an imaginary number is called a complex number. A complex number is usually represented by z and has the form a + ib. Here, both a and b are real numbers. The real part, denoted by Re(z), is represented by the value "a," and the imaginary part, represented by "b," is represented by Im(z). Also known as an imaginary number, ib.
Given z₁ = 2 + √3i,
z₂ = 1 - √3i
to calculate the sum
z₁ + z₂ = 2 + √3i + 1 - √3i
sum of complex number is done by adding real part and imaginary part separately,
+ √3i and - √3i is canceled
z₁ + z₂ = 3 + 0i = 3
Hence the sum is 3.

6x + 3y = 18
Graphic
Answer:
x and y are two
Step-by-step explanation:
six times two equals twelve and 3 times two equals six and six plus twelve equals 18
Answer: x=-1/2y3
Step-by-step explanation:
Step 1: Add -3y to both sides.
6x+3y+−3y=18+−3y
6x=−3y+18
Step 2: Divide both sides by 6.
6x/6=-3y+18/6

Infinitely many solutions
Answer:
exactly one solution: 3/11 = z
Step-by-step explanation:
-2z + 10 +7z = 16z + 7
combine like terms
5z + 10 = 16z + 7
-7 -7
5z + 3 = 16z
-5z -5z

Ikram invests £7000 in a savings account paying compound interest for 2 years.
In the first year, the rate of interest is x%.
At the end of the first year the value of Ikram's investment is £7273
In the second year, the rate of interest is x/3%
What is the value of Ikram's investment at the end of the 2 years?
Answer:
The answer is £7367.55
Step-by-step explanation:
Find the interest.
£7273 - £7000 = £273
Then, find the multiplier for the 1st year.
273/7000 = 0.039
Then, find the multiplier for the next year.
It says it is x/3, with x being the 1st year multiplier, so do 0.039/3 = 0.013
Afterwards, multiply the total money from the 1st year with the 2nd years multiplier.
£7273 x 1.013 = £7367.55
Hope this helps :)

consider this equation. 7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8) Mia solved the equation and determined that m=2. Is she correct?
A She is incorrect because when substituting 2 for m the result was a true statement.
B She is incorrect because when substituting 2 for m the result was a false statement.
C She is correct because when substituting 2 for m the result was a true statement.
D She is correct because when substituting 2 for m the result was a false statement.
Answer:
B) She is incorrect because when substituting 2 for m the result was a false statement.
Step-by-step explanation:
Let's solve it for ourselves and see if Mia is correct:
7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)
7.8+1.5m+0.8=-6.4m+2m-3.2
1.5m+8.6=-4.4m-3.2
8.6=-5.9m-3.2
11.8=-5.9m
-2=m
m=-2
Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.
