You roll two die. What is the probability you will roll a 4, then roll a number less than 3?
A) 1/36
B) 1/9
C) 1/6
D) 1/18
Answer:
B 1/9
Step-by-step explanation:
Because there are 6 sides of a die then your adding 3 to the 6
I think. (please dont hate me if im wrong!!)
The probability that if we will roll a 4, then rolling next a number less than 3 is given by: Option D: 1/18
What is the chain rule in probability for two events?For two events A and B:
The chain rule states that the probability that A and B both occur is given by:
[tex]P(A \cap B) = P(A)P(B|A) = P(B)P( A|B)[/tex]
Which pair of events are called independent events?When one event's occurrence or non-occurrence doesn't affect occurrence or non-occurrence of other event, then such events are called independent events.
Symbolically, we have:
Two events A and B are said to be independent iff we have:
[tex]P(A \cap B) = P(A)P(B)[/tex]
For this case, let we define two events:Then A and B are independent as their outcomes are not directly related or prone to affect each other assumingly.
Thus, probability of rolling a 4, then rolling a number less than 3 is:
[tex]P(A \cap B) = P(A)P(B)[/tex]
Total number of outcomes for any roll = n(S) = 6
Favorable number of outcomes for event A = n(A) = 1 (since a 4 can occur in 1 way out of 6 results)
Thus, P(A) = n(A)/n(S) = 1/6
And, favorable number of outcomes for event B = n(B) = 2 (since numbers less than 3 are only 1 and 2, so two outcomes possible)
Thus, P(B) = n(B)/n(S) = 2/6
Hence, probability of rolling a 4, then rolling a number less than 3 is:
[tex]P(A \cap B) = P(A)P(B) = \dfrac{1}{6} \times \dfrac{2}{6} = \dfrac{2}{36} = \dfrac{1}{18}[/tex]
Therefore, the probability that if we will roll a 4, then rolling next a number less than 3 is given by: Option D: 1/18

Make Sense and Persevere Paxton, a summer camp counselor, has a budget of $300 to spend on caps and T-shirts for a summer camp.
plz help this is due soon!!!
Answer:
9 shirts and 10 caps
Step-by-step explanation:
Buying one t shirt costs 20 dollars, and one cap would cost 12 dollars. If Paxton bought one cap and one shirt, that would cost 32 dollars. If we multiply that by 9, we get 288. So Paxton can buy 9 shirts and 9 caps with 288 dollars. Paxton has 12 dollars left, so Paxton can buy one more cap to entirely spend the budget.

How to solve stacked similar figures
Answer:
Step-by-step explanation:
You can identify similar polygons by comparing their corresponding angles and sides. As you see in the following figure, quadrilateral WXYZ is the same shape as quadrilateral ABCD, but it’s ten times larger (though not drawn to scale, of course). These quadrilaterals are therefore similar.
similar polygons: For two polygons to be similar, both of the following must be true:
Corresponding angles are congruent.
Corresponding sides are proportional.
To fully understand this definition, you have to know what corresponding angles and corresponding sides mean. (Maybe you’ve already figured this out by just looking at the figure.) Here’s the lowdown on corresponding. In the figure, if you expand ABCD to the same size as WXYZ and slide it to the right, it’d stack perfectly on top of WXYZ.

The total cost of Anja’s trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and value of x, the cost of each cavity filling?
A. 4 x + 89.95 = 628.35; x = 134 dollars and 60 cents
B. 4 (89.95) + x = 628.35; x = 268 dollars and 55 cents
C. 4 x + 89.95 = 628.35; x = 179 dollars and 58 cents
D. 4 (89.95) + x = 628.35; x = 538 dollars and 40 cents
Answer:
A

Does this graph represent a function ?
Which equation describes a line perpendicular to line r that passes through the point (3,-6) x-3y=21, 3x+y=3, 3x-y=15, 3x-y=3
Answer:
See Explanation
Step-by-step explanation:
Missing in the question is the slope of line r.
We'll assume that the slope (m) of line r is
[tex]m = -\frac{1}{3}[/tex]
When two lines are perpendicular, their slope are related in:
[tex]m_2 = -1/m_1[/tex]
[tex]m_2 = -1/\frac{-1}{3}[/tex]
[tex]m_2 = -1 * -3[/tex]
[tex]m_2 = 3[/tex]
The equation of the (3,-6) is:
[tex]y - y_1 = m(x - x_1)[/tex]
Where
[tex](x_1,y_1) = (3,-6)[/tex]
So:
[tex]y - (-6) = 3(x - 3)[/tex]
[tex]y +6 = 3x - 9[/tex]
Make y the subject
[tex]y = 3x - 9 - 6[/tex]
[tex]y = 3x - 15[/tex]
Please note that this answer might be incorrect to you based on the assumed value. However, the step will guide you in solving similar questions

Step-by-step explanation:
2x+13
x=5
=2×5+13
=10+13
=23
Answer:
23
Step-by-step explanation:
When I was first introduced to algebra, One thing that had me stumped for the longest time is terms like "2x". This is because nobody explained to me that saying "2x" and similar terms implies a multiplication. so "2x" actually means "2 × x". I only mention this because I thought maybe it would help.
To solve it then, all we need to do then is think of "x" as meaning five, and it being multiplied by 2
We're given this:
[tex]2x + 13[/tex]
which you can also read as this:
[tex]2 \times x + 13[/tex]
We're told x equals five, so we can say:
[tex]2 \times 5 + 13[/tex]
Remember when solving this, that multiplication and division always come before addition and subtraction, so let's do the multiplication:
[tex]10 + 13[/tex]
and then add it up:
[tex]23[/tex]
So the final answer is twenty-three.

The two kids next to your locker are arguing over who got the better deal on the new cell phone plan billy pay $30 for his new phone and only pays $12.50 each month with free texting Annie got her new phone for free in only pays $20 a month how many months will both billy Annie have paid the same amount for the new cell phone plans you must write and solve an equation
Answer:
They will both have paid the same amount after 4 months
Step-by-step explanation:
Assume that they will pay the same amount after x months
∵ Billy pays $30 for his new phone
∵ He only pays $12.50 each month
→ Find how much he will pay in x month
∴ He will pay → 30 + 12.50x
∵ Annie got her new phone for free
∵ She only pays $20 a month
→ Find how much she will pay in x month
∴ She will pay → 20x
∵ They will pay the same amount
→ Equate their expressions above
∴ 20x = 30 + 12.50x
→ Subtract 12.50x from both sides
∵ 20x - 12.50x = 30 + 12.50x - 12.50x
∴ 7.50x = 30
→ Divide both sides by 7.50
∴ x = 4
∴ They will both have paid the same amount after 4 months
Kimoni wants to purchase a pair of shoes that are on sale for 10% off the regular price
of $64.00. Which is the sale price of the shoes?
Answer:
the price of the pair of shoes are $57.60
Step-by-step explanation:
So you first need to find out what 10% is in $64 so your going to multiply 0.1 (10% in decimal form is 0.1 ) by 64 to get 10% of the original price.
64 * 0.1 = $6.40
so now we are going to subtract $6.40 from $64 for the sale price:
$64.00 - $6.40 = $57.60
so the sale price is $57.60

5) Go....
[tex]17 = 4x + 1[/tex]
[tex]4x + 1 = 17[/tex]
Subtract sides 1
[tex]4x + 1 - 1 = 17 - 1[/tex]
[tex]4x = 16[/tex]
Divide sides by 4
[tex] \frac{4x}{4} = \frac{16}{4} \\ [/tex]
[tex]x = 4[/tex]
_________________________________
6) Go...
[tex]2x - 2 = 16[/tex]
Add sides 2
[tex]2x - 2 + 2 = 16 + 2[/tex]
[tex]2x = 18[/tex]
Divide sides by 2
[tex] \frac{2x}{2} = \frac{18}{2} \\ [/tex]
[tex]x = 9[/tex]
_________________________________
7) Go...
[tex]95 = 7x + 18[/tex]
[tex]7x + 18 = 95[/tex]
Subtract sides 18
[tex]7x + 18 - 18 = 95 - 18[/tex]
[tex]7x = 77[/tex]
Divide sides by 7
[tex] \frac{7x}{7} = \frac{77}{7} \\ [/tex]
[tex]x = 11[/tex]
_________________________________
8) Go...
[tex]78 + 9x - 6 = 180[/tex]
[tex]9x + 72 = 180[/tex]
Subtract sides 72
[tex]9x + 72 - 72 = 180 - 72[/tex]
[tex]9x = 108[/tex]
Divide sides by 9
[tex] \frac{9x}{9} = \frac{108}{9} \\ [/tex]
[tex]x = 12[/tex]

Um- help-.. please don’t comment if you don’t know
Answer:
Each point does NOT ALWAYS give the same amount of tickets.
11 point would most likely give 90 tickets.
Step-by-step explanation:
2 points give 18 tickets = 9 tickets per point
3 points give 27 tickets = 9 tickets per point
9 points give 72 tickets = 8 tickets per point
You can add the 2 point value with the 9 point values to find out many point it takes to get to 90 tickets.
18(2 tickets) + 72(9 tickets) = 90(11 tickets)
Answer:
Im, not as sure, but I think it's 10 points!
Step-by-step explanation:
If you divide the tickets by the points, they always come up as a whole number ( 9, 9 , then 8.) To be honest, I was a little stuck, but after messing around,, if you divide 90 by 10, you get a whole number, 9. so I was just thinking this would be right? Maybe? The Points keep increasing, so that follows that pattern...
Honestly, I hope this helps, but I'm super sorry if that is wrong!!
