Answer:
3/8
Step-by-step explanation:
The probability of picking either a Queen or a Jack from each pile is always 1/2 (as there are only 2 cards).
There are only 3 ways in which Lisa can draw two Queens and a Jack:
Queen, Queen, Jack
Queen, Jack, Queen
Jack, Queen, Queen
The probability of each one happening is 1/8
This is because there is a 1/2 chance of picking a Queen or a Jack from each pile and to calculate the probability that Lisa will pick a Queen AND a Queen AND then a Jack (for example) you multiply the probabilities together:
1/2 x 1/2 x 1/2 = 1/8
This is the same for other examples and since there are only 3 ways that Lisa can draw two Queens and a Jack you multiply 1/8 by 3 (you add 1/8 together 3 times) to get 3/8
It can be represented on a tree diagram however I am not sure how I can show images/drawings on this
Please help! There is 2 question! Thank you so much
Answer:
The answers are:
Question 23: 140
Question 24: 25
Step-by-step explanation:
Question 23:
Since 25% is 1/4 of the total amount of members in the club, we need to multiply the amount of drum player (35), by 4.
35 x 4 = 140
Question 24:
The absolute value of -25 is 25, since the absolute value is the value without any signs.
Therefore, the answers are:
Question 23: 140
Question 24: 25

Which one of these is a square number?
15
39
81
132
Answer:
81
Step-by-step explanation:
i need to know the rest of the equation just letter R
Notice that 2/3 times 12 is...
(2/3)*12 = (2/3)*(12/1)
(2/3)*12 = (2*12)/(3*1)
(2/3)*12 = 24/3
(2/3)*12 = 8
So that explains the 8 on the right hand side.
For the blank, we'll multiply 2/3 by the 9y term like so
(2/3)*9y = ((2/3)*(9/1))y
(2/3)*9y = ((2*9)/(3*1))y
(2/3)*9y = (18/3)y
(2/3)*9y = 6y
This means 6y goes in the blank.
If your teacher only cares about the coefficient, aka number out front of the variable, then you'd just go for 6. That's my guess as to what your teacher wants. It seems to fit with the template you show and that would mean R goes in the second to last slot.

if it's 7:20 PM what time would it be if 90 minutes passed? HELP!!!
Answer:
The answer is 8:50 PM.
Step-by-step explanation:
If it's 7:20 PM, then what time is it 90 minutes from now?
Start with 30. It would be 7:50 PM. So, add 10 more minutes (with 50 minutes more to add) and you have 8:00 PM. Add your last 50 minutes. The time would be, as shown above, 8:50 PM.

4) Make sure the bottom numbers (the denominators) are the same
Subtract the top numbers (the numerators). Put the answer over the same denominator.
Simplify the fraction (if needed)
Ex 3rd qu) 1/6 - 2/10 multiply out 6x 10 = 60 and 10 x 6 to the other denominator and 10 x 1 to 1st numerator and 6 x 2 to 2nd numerator
= 10/ 60 - 12/60 = -2/60 simplified as -1/30

2)
a. x= -84
b. x= 9/4 or 2.25 in decimal form
c. x= 53/5 or 10.6 in decimal form
d. x= 31/2 or 15.5 in decimal form
3)
a. y= -10
b. y= -28
c. y= -114
d. y= 68
Step-by-step explanation:
2) substitute y as 7
a. y= x+91
7=x+91
7-91=x
-84=x
x= -84
——————
b. y= 4x-2
7=4x-2
7+2=4x
9=4x
9/4=x
x=9/4 or 2.25
————————
c. y= 5x-46
7= 5x-46
7+46=5x
53=5x
53/5=x
x=53/5 or 10.6
—————————
d. y= 6x-86
7= 6x-86
7+86=6x
93=6x
93/6=x
31/2=x
x= 31/2 or 15.5
—————————
3) substitute x as 13
a. y= -x+3
y= -13+3
y= -10
——————
b. y= -2x-2
y= -2(13)-2
y= -26-2
y=-28

c. y= -3x-75
y= -3(13)-75
y= -36-75
y= -114

I don’t understand question b can somebody explain it for me?
5+k/4=3 please explain thoroughly
To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.
Remove the DenominatorMultiply by 4 on both sides of the equation.
[tex]\displaystyle 4(5 + \frac{k}{4}) = 4(3)[/tex]
[tex]\displaystyle 20 + k = 12[/tex]
SimplifySubtract 20 from both sides to isolate the k.
[tex]20 - 20 + k = 12 - 20[/tex]
[tex]\boxed{k = -8}[/tex]
The final answer is k = -8.
