When a die is rolled twice, the probability of getting a 3 and then a 5 is 1/36.
When a die is rolled twice, the following combinations are possible:
1, 1 - 1, 2 - 1, 3 - 1, 4 - 1, 5 - 1, 6
2, 1 - 2, 2 - 2, 3 - 2, 4 - 2, 5 - 2, 6

5, 1 - 5, 2 - 5, 3 - 5, 4 - 5, 5 - 5, 6
6, 1 - 6, 2 - 6, 3 - 6, 4 - 6, 5 - 6, 6
Thus, the sample space is 36.
3, 5 only occurs once in the sample space.
∴ P (3 and 5) = 1/36.
Hence, the probability of rolling a 3 and then a 5 is 1/36.

Helpp, practice problems.
By comparing the intercepts of the linear equation with the ones in the graph, we conclude that the given graph corresponds with the linear equation.
How to know if the graph represents the given equation?
Here we have the linear equation:
1.5*s + 3.5*c = 21
And we have a graph, which we want to see if it is the graph of the linear equation.
To check this, we just need to look at the intercepts, the variable "c" is on the vertical axis and the variable "s" is on the horizontal axis.
The "s" intercept is what we get when we take c = 0, replacing that we will get:
1.5*s + 3.5*0 = 21
1.5*s = 21
s = 21/1.5 = 14
This means that the line should pass through the point (14, 0), and we can see that this happens.
The other intercept is what we get when we take s = 0.
1.5*0 + 3.5*c = 21
c = 21/3.5 = 6
The other intercept is at (0, 6), which we also can see on the graph.
With that is enough to conclude that the given graph represents the given linear equation.

Find the probability that a point chosen at random lies in the shaded region.
A. 0.22
B. 0.25
C. 0.28
D. 0.32
The probability that a point is chosen at random will lie in the shaded area will be 0.32.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Here favorable outcomes will be the shaded portion and the total outcome will be the total circular portion.
Favorable Outcome = Area of shaded portion = 1/2 x 18 x 18/2
= 81 inch sq.
Total Outcome = Total area = 81 π inch sq.
Probability, P(E) = 81/ 81 π = 1/32
Hence, the probability that a point chosen at random will lie in the shaded area is 0.32.

What is the solution of √4 x-23 -3 = 2 ?
The solution of the given equation √(4x-23) - 3 = 2 is (x = 14.25).
What is meant by square numbers?A 'Square Number' is the result of multiplying a number or integer (not really a fraction) by itself.
For instance, 3 multiplied by 3 equals 3 squared, or 3 x 3 = 32. So, in essence, a square number is really the exponential form of multiplying a number or integer by itself. Also, if we multiply the number on its own again, we get the integer's cube, a x a x a = a³.Now, as per the given equation;
√(4x-23) - 3 = 2
This could also be written as;
√(4x-23) = 2 + 3
√(4x-23) = 5
Now, squaring on the both side;
(4x-23) = 25
Open the brackets;
4x - 32 = 25
4x = 25 + 32
4x = 57
x = 14.25
Therefore, the solution of the given equation √(4x-23) - 3 = 2 is calculated as (x = 14.25).

Theatre tickets have a regular cost of £48 each and are on offer for
1/6
off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip
Answer: 38 pounds
Step-by-step explanation: School allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off
therefore 4/5*35 = 28 for the tickets
:
A train ticket for the day will cost £15 each.
therefore total cost for each: 28 + 15 = 43 pounds each
:
If 2 teachers and the maximum number of students attend, how much money will the school have left over?
:
let s = no. of students
43(s+2) =< 1500
43s + 86 =< 1500
43s =< 1500 - 86
43s =< 1414
s =< 1414/43
s =< 32.88, 32 students max
:
find how much left over. plus 2 teachers = 34 people
1500 - 43(34) =
1500 - 1462 = 38 pounds left over

Which equation does NOT represent a direct variation?
a. y=x
b. 2 x-y=5
c. 2 x-y=0
d. 2 x-5 y=0
The graph of 2x - y = 5 does not represent a direct variation.
Direct variation is variation in which the quotient of the two variables is constant. A constant ratio of two quantities means that one quantity varies directly with the other or that the two quantities vary directly. In symbols, the direct variation formula is y=k*x or k=y/x.
k is known as the constant of variation or the constant of proportionality.
This means that as x increases, y increases, and as x decreases, y decreases, and their ratio is always the same.
The graph of the direct variation equation is a straight line through the origin.
The graph of 2x-y =5 does not pass through the origin, so it does not represent a direct variation. (consult the images attached below).

Find the tenth term of each arithmetic sequence. 15,23,31, ...........
The 10th term of an Arithmetic Progression (AP) is (a₁₀ = 87.)
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between the two mathematical orders is a constant value (AP). Arithmetic Sequence is another name for it.
We'd come across a few important words in AP that were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP also can be described in aspects of common differences.
The following is the formula for evaluating an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the given sequence is; 15,23,31, ...........
Consider the first term is'a₁' = 15
Consider 'a₂' = 23 is the second term.
Consider the third term is 'a₃' = 31
Calculate the common difference;
d = a₂ - a₁
Put the values in the above obtained equation;
d = 23 - 15 = 8
Now, to estimate the value of the 10th term using the formula of nth term.
an = a + (n − 1) × d , n = total number of terms = 10.
Put all the values;
a₁₀ = 15 + (10 - 1) × 8
a₁₀ = 15 + 9 × 8
a₁₀ = 15 + 72
a₁₀ = 87
Therefore, the value of the 10th term is calculated as a₁₀ = 87.
