Answer: [tex]\dfrac{b}{5}[/tex]
Step-by-step explanation:
Given: Let b = Total number of books.
Total shelves = 5
Number of books on each shelf = (Total number of books) ÷ (Total shelves)
= b ÷ 5
[tex]=\dfrac{b}{5}[/tex]
The required expression for the number of books on each shelf = [tex]\dfrac{b}{5}[/tex]

an ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. this sum is recorded as the outcome of a single trial of a random experiment. compute the probability of each of the following events. event : the sum is greater than 5. event : the sum is divisible by 2 or 3 (or both).
Probability of sum greater than 5 event is reduces to 13/18 .
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
probability of getting number whose sum is divisible by 2 and 3 both is 6/36 which reduces to 1/6 .
The sample space of rolling two dice has 36 possible outcomes. Remember that the "sample space" is a set which contains all possible outcomes. (1,1)(2,1)(3,1)(4,1)(5,1)(6,1)(1,2)(2,2)(3,2)(4,2)(5,2)(6,2)(1,3)(2,3)(3,3)(4,3)(5,3)(6,3)(1,4)(2,4)(3,4)(4,4)(5,4)(6,4)(1,5)(2,5)(3,5)(4,5)(5,5)(6,5)(1,6)(2,6)(3,6)(4,6)(5,6)(6,6)
The probability of the sum is greater than 5 event is 26/36 which reduces to 13/18 .And the probability of getting number whose sum is divisible by 2 and 3 both is 6/36.

The teacher has the following cards in a bag::
what is the probability that the teacher randomly selects a card with an 8 on it?
Answer:
20% or .20
Step-by-step explanation:
There are a total of 10 cards in the sample.
Of these 10 cards there are 2 of them with the number 8 on them.
To find the probability, you divide the part (2) over the whole (10)
2/10 = .20
Then you can multiply by 100 to find the percent
(.20)(100) = 20%
Therefore, if the teacher were to select a card at random there is a 20% chance that it has the number 8 on it.
I hope this helps!

Find the equation of the line.
y=__x+__
Answer:
y=4x-9
Step-by-step explanation:
The equation of a line is typically written in slope-intercept form, which is y=mx+b. Here's what the variables mean:
y=the y-coordinate
m=the slope
x=the x-coordinate
b=the y-intercept (the point on the line that intercepts the y-axis)
The only values that we have to calculate to find the equation are the slope of the line and the y-intercept. Let's start off by finding the slope.
To find the slope of a line, we would need to find 2 points that fall on the line, [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] and plug them into the expression [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use the points (1, -5) and (3, 3).
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{3-(-5)}{3-1}[/tex]
[tex]=\frac{3+5}{3-1}\\= \frac{8}{2}\\= 4[/tex]
Therefore, the slope of the line is 4.
To find the y-intercept, all we need to do is look at which point the line crosses the y-axis, and that point is -9.
Finally, we plug the slope and the y-axis into the equation y=mx+b as m and b.
y=mx+b
y=4x-9

the dimensions of a rectangular plot of land are 28.3m by 53.7m. Find
1) the perimeter of the land, correct to the nearest 10
2) the area of grass needed to fill up the entire plot of land, correct to the nearest 100m^2
also show the steps
Answer:
1. Answer is 160 m
2. Answer is 1500 m²
Step-by-step explanation:
perimeter = 2(l+b)
which implies 2( 28.3 + 53.7) m = 160 m
Area is length× breadth
which implies 28.3× 53.7 = 1500 m²

Answer: Simplified Equation (10x-10)
Answer if 3=x is 20
Step-by-step explanation:
the original side lengths are 3x and (2x-5) so multiply both those by 2.
Now you have 6x and 4x-10.
Now combine those and you have 10x-10.
Then plug in 3 for x

How long will it take for a debt to double at 42% p.a. compound interest?
According to the given statement ,
a debt to double at 42% p.a. compound interest will take approx 2 years.
What is compound interest ?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
Compound interest is calculated on the initial principal of a deposit or loan, which also takes into account all of the accumulated interest from prior periods.
The yearly interest rate is raised to the number of compound periods minus one, and the starting principal amount is multiplied by both of these factors.
According to the given data,
Let principal = P
Time = t
Rate == 42%
Amount = A
Given Condition is A = 2P
=> P[1+ r/100]ⁿ = 2P
=> P [1 + 42/100 ]ⁿ = 2P
=> (1.42)ⁿ=2
n= log₁.₄₂ 2 =0.301/0.152
n=1.980≅2
Hence , the time it take for a debt to double at 42% p.a. compound interest is approx 2 years.
