Answer:
P(A) = 31/1296
P(B) = 125/1296
Step-by-step explanation:
Here, we want to find P(A) and P(B)
Let’s start with A
In a roll of a die, the probability that there will be a 5 is 1/6
The probability of not having a 5 is therefore 1-1/6 = 5/6
So out of four rolls , we want to find the probability of having at least two fives
This means there could be 2, 3 or 4 fives;
For two fives;
We have 2 fives and two non-fives
= (1/6 * 1/6 * 5/6 * 5/6) = 25/1296
For 3 fives;
we have 3 fives and 1 non five
= 1/6 * 1/6 * 1/6 * 5/6 = 5/1296
For 4 fives;
= 1/6 * 1/6 * 1/6 * 1/6 = 1/1296
So the probability of at least two fives is;
1/1296 + 5/1296 + 25/1296 = 31/1296
Event B is the probability that there is at most one five among the four rolls
That means there are 3 non fives and 1 five
P(B) = 1/6 * 5/6 * 5/6 * 5/6 = 125/1296

Answer:
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
Step-by-step explanation:
Using, the formula y1+y2/x1-x2,
Choosing any two points, make the expression:
1-2/125-155
simplify:
-1/-30
the slope of the equation is -1/-30.
to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:
y would be 2
x would be 155
b is the y intercept
2= -1/-30•155 + b
2=5⅙+b
b = - 3⅙
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
Jack's birthday is in 8 weeks. How many days is it until Jack's birthday? Complete the explanation on how you could use a number line to solve. Jack's birthday is in days. I would draw equal jumps of beginning at 0 on the number line. The jumps end at .
Answer:
Jack's birthday is in 56 days.
The jumps end at point 56 on the number line.
Step-by-step explanation:
Since one week has 7 days.
So, 8 week = 8 x 7 =56 days.
Hence, Jack's birthday is in 56 days.
On the number line, the current time is being represented by 0.
When I take one jump from 0, I will reach the point 1 on the number line, which corresponds to 1 day.
Again, in my 2nd jump from point 1 on the number line, the next point on the number line will be 2 which corresponds to 2 days.
This process repeats until I complete the 56 jumps to get point 56 on the number line, which corresponds to 56 days.
In this way, the number line can be used to solve.
Hence, the jumps end at point 56 on the number line.

2s+1=3s
7s+3s=10
10-3=7s
The 240 ninth-graders at a high school are divided into homeroom groups of 10 or 12 students. This equation models the
situation, where x represents the number of 10-student groups and y represents the number of 12-student groups:
10x +12y = 240.
? Question
Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.
The x-intercept is located at ( ,0).
The y-intercept is located at (0, )
The slope of the line represented by this equation is[ ]
Answer: The X intercept is located at (24,0) The Y intercept is located at (0,20)
The slope of the line represented by this equation is -5/6
Step-by-step explanation:
The x-intercept is located at (24, 0).
The y-intercept is located at (0, 20)
The slope of the line represented by this equation is (-5/6).
We have,
Equation:
10x + 12y = 240
This can be written in the slope-intercept form.
y = mx + c
Where m is the slope and c is the y-intercept.
Now,
10x + 12y = 240
12y = 240 - 10x
12y = -10x + 240
y = (-10/12)x + 240/12
y = (-5/6)x + 20
Now,
The y-intercept is 20.
This is when x = 0.
And,
The x-intercept is when y = 0.
0 = (-5/6)x + 20
(5/6)x = 20
x = 4 x 6
x = 24
And,
The slope is (-5/6)
Thus,
The x-intercept is located at (24, 0).
The y-intercept is located at (0, 20)
The slope of the line represented by this equation is (-5/6).

What is 37 divided by 4
Answer:
9.25
Step-by-step explanation:
The quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.
To solve 37 divided by 4 step by step:
Step 1: Divide the first digit of the dividend (37) by the divisor (4):
37 ÷ 4 = 9
Step 2: Multiply the quotient (9) by the divisor (4) to get the product:
9 × 4 = 36
Step 3: Subtract the product (36) from the dividend (37) to find the remainder:
37 - 36 = 1
Step 4: Bring down the next digit (0) from the dividend to the remainder:
Remainder: 10
Step 5: Divide the new number (10) by the divisor (4):
10 ÷ 4 = 2
Step 6: Multiply the new quotient (2) by the divisor (4) to get the product:
2 × 4 = 8
Step 7: Subtract the product (8) from the remainder (10) to find the new remainder:
10 - 8 = 2
Step 8: Since the remainder (2) is less than the divisor (4), we can stop here.
Therefore, the quotient of 37 divided by 4 is 9 with a remainder of 2, or written as a mixed number, it is 9 2/4 or 9 1/2.

3x - 4 + 6x = -31
17 = 3x - 10
2x + 6 = 4x - 8
17x - 5(3x - 11) = 41
5x - (3x - 6) = 18
6x - 3(4 - 5x) = 30
x - (-5) = 7
This is a lot of questions-
I did them all on a calculator.

3x - 4 + 6x = -31
3x + 6x - 4 = -31
9x - 4 = -31
9x = -27
Answer: x= -3
2.)
17 = 3x - 10
3x -10 = 17
-10 = -10
3x = 27
divide both sides by 3
Answer: x= 9
3.)
2x + 6 = 4x - 8
-6 = -6

5x - (3x - 6) = 18
2x + 6 = 18
-6 both sides
2x = 12
divide both sides by 2
Answer: x = 6

Which of the following graphs shows the solution set to t > 4 or t < -1?
Answer:
The second graph
Step-by-step explanation:
t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)
The second graph represents the solution set to t > 4 or t < -1.
What are open and closed interval ?In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.
According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.
We know when we represent less than or greater than in the number line we represent it as an open circle.
So, t > 4 will be represented by an open circle on the number line starting at 4 but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.

One crate can store 12^3 toys. A warehouse receives 12^7 toys. Enter the number of crates
needed to store all the toys the warehouse received.
Answer: The number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Step-by-step explanation:
Given: Total number of toys = [tex]12^7[/tex]
Number of toys in one crate = [tex]12^3[/tex]
The number of crates needed to store all the toys the warehouse received.
= (Total number of toys) ÷ (Number of toys in one crate)
[tex]=12^7\div 12^3 = 12^{7-3}\ \ \ [a^m\div a^n=a^{m-n}]\\\\=12^4[/tex]
Hence, the number of crates needed to store all the toys the warehouse received = [tex]12^4= 20736[/tex]
Answer:
12^4 or 20736
Step-by-step explanation:
Since the warehouse has 12^7 toys and you need to find how much crates that can fit 12^3 toys will store all the toys, you must divide 12^7 by 12^3.
When dividing radical expressions, remember:
a^3/a^2=a^1 This kind of acts like subtracting the squared number
a^3 * a^2 = a^5 This kind of acts like adding the squared number
(a^3)^2 = a^6 This kind of acts like multiplying the squared number
Therefore, if you use the methods above, 12^7 / 12^3 = 12^4
12^4= 20736

2540 centimeters are equal to how many inches ?
Answer:1000
Step-by-step explanation
There are 1000 inches equal to 2540 centimeters
Unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
To convert centimeters to inches, we have to use the conversion factor 1 inch = 2.54 cm.
To determine how many inches are in 2540 cm, first we divide 2540 by 2.54:
2540 cm ÷ 2.54 = 1000 inches
Therefore, we can conclude that 2540 centimeters are equal to 1000 inches.
