The probability of randomly selecting an insect is 2/15.
What is probability?
It is a measure of happening or non happening of the outcomes of a random experiment.
Formula for probabilityP(E) = number of favorable outcomes/Total number of outcomes
Where, P(E) is the probability of any event.
Let E be an event of selecting an insect.
According to the given question
We have
Total number of insects = 10
Total number of trees = 8
Total number of flowers = 8
Total number of birds = 4
Now, the total number of outcomes = 10 + 8 + 8 + 4 = 30
Total number of favorable outcomes = 4
Therefore,
The probability of selecting an insect = [tex]\frac{4}{30} =\frac{2}{15}[/tex]

The heights of Rahul, Akash, Meera and Lakshmi are 1.54m, 1500mm,
152cm,1560mm respectively.
a) Arrange their heights in ascending order.
b) Who is the tallest among them?
Answer:
A) Akash (1.5m), Meera (1.52), Rahul (1.54m), Lakshmi (1.56m)
B) Lakshmi is the tallest, 1.56m tall
Step-by-step explanation:
Rahul- 1.54m
Akash- 1500mm
Meera- 152cm
Lakshmi- 1560mm
Let's start by converting all the measurements to meters.
Rahul is already in meters, so he can just stay the same.
1500mm = 1.5m
152cm = 1.52m
1560mm = 1.56m
So our new measurements are:
Rahul- 1.54m
Akash- 1.5m
Meera= 1.52m
Lakshmi= 1.56m
We can now make our conclusions.
A) Akash (1.5m), Meera (1.52), Rahul (1.54m), Lakshmi (1.56m)
B) Lakshmi is the tallest, 1.56m tall
Answer:
Step-by-step explanation:
Let's convert all the heights to meters:
Rahul 1.54m
Akash 1.50 m
Meera 1.52 m
Lakshmi 1.56m
Now, let's arrange their heights in ascending order (shortest to tallest):
Akash 1.50 m
Meera 1.52 m
Rahul 1.54m
Lakshmi 1.56m
a) 1500 mm, 152 cm, 1.54 m, 1560 mm
b) therefore Lakshmi is the tallest.

RAMPS Rodney is rolling marbles down a ramp. Every second that passes, he measures how far the marbles travel. He records the information in the table shown below.
Make a conjecture about how far the marble will roll in the fifth second.
Using the principle of common difference , we can observe that the distance moved per roll increases by a constant amount of centimeters . Hence, the distance moved in the 5th roll is 180 cm
Setting up a proportional relationship :
Second = S Distance = dThe common difference between each roll can be obtained thus :
d2 - d1 = d3 - d2 = d4 - d3
60 - 20 = 100 - 60 = 140 - 100
40 = 40 = 40
Hence, the common difference = 40
The distance obtained on the fifth roll :
d(5) = d(4) + common difference
d(5) = 140 + 40
d(5) = 180
Therefore, the distance obtained on the fifth roll is 180 cm

Anna says that 5 1/3 is not a rational number because it’s not in the fraction form of a/b. Do you agree? plsss help
Answer:
No.
Step-by-step explanation:
A rational number is a number that can be written in the form a/b, where a and b are integers. A rational number does not have to be written in the form a/b. I just needs to be able to be written in that form.
Can 5 1/3 be written as a fraction of integers?
5 1/3 = 5 + 1/3 = 15/3 + 1/3 = 16/3
5 1/3 = 16/3
16/3 is in the form a/b, where a and b are integers.
Since 5 1/3 can be written as a fraction of integers, it is rational.
Anna is incorrect.
What is the value of x in the equation 2(x−3)+9=3(x+1)+x?
a. x = −3
b. x = −1
c. x = 0
d. x = 3
Answer:
x=0
Step-by-step explanation:
1st Step(Plug in 0 for x): 2(0-3)+9=3(0+1)+x
2nd Step(Simplify): 2*(-3)+9=3*(1)+x
3rd Step(Multiply): -6+9=3+x
4th Step(Add): 3=3+x
5th Step(Subtract 3 from both sides): x=0
For any questions saying what is the value of x in the equation, just plug in one of the options from a,b,c,d. And work from there

represents the cost y of bowling games. Interpret the parameters of the function.

$
represents the shoe rental charge.
The parameters of a linear function are the slope, and the intercepts.
3.5 represents the price per game4 represents the shoe rental chargeA linear function is represented as:
[tex]\mathbf{y = mx + b}[/tex]
Where:
m represents the slope or the rates
b represents the y intercept or the initial value of the function.
So, by comparison:
[tex]\mathbf{m = 3.5}[/tex]
[tex]\mathbf{b = 4}[/tex]
So, we have:
The price per game is 3.5 (i.e. the slope), and the shoe rental charge is 3.5 (i.e. the y-intercept)

the perimeter of a rectangular field is 344m.if the length of the field is 93m.what is it’s width?
Answer:
79m
Step-by-step explanation:
344-(93x2)=158
158/2=79m
Step-by-step explanation:
perimeter = 344
length = 93
perimeter of rectangle = 2( l+ b )
344 = 2 (93 + b)
344÷2 = 93 + b
172 = 93 + b
172 - 93 = b
79 = b
in other words width is 79

Consider the system of equations.
5x + 2y = 12
5x – 2y = 28
What is the solution to the system of equations? Show work using substitution or elimination to support your answer.
A (4, -4)
B (-4, 4)
C (5, -6.5)
D (4, 16)
Answer:
A. (4, -4)
Step-by-step explanation:
Equation form x = 4, y = −4
Answer:
Option A
Step-by-step explanation:
5x + 2 y = 12 -----------(I)
5x - 2y = 28 ------------(II)
Add equation (I) & (II). So, y will be eliminated and we will get the value of x
(I) 5x + 2y = 12
(II) 5x -2y = 28 {Now add}
10x = 40
x = 40/10
x = 4
Plugin x = 4 in equation (I)
5*4 + 2y = 12
20 + 2y = 12
2y = 12 - 20
2y = -8
y = -8/2
y = -4
3 (1 - 3x) = 2 (- 4x +7)
Answer: x = -11
Step-by-step explanation:
Expand the expression (distributive property): 3 - 9x = -8x + 14
// subtract 14 from both sides = -11
// add 9x on both sides = x
Simplify: x = -11

Step-by-step explanation:
1) Rearrange Terms
[tex]3(-3x+1)=2(-4x+7)[/tex]
2) Distribute
[tex]-9x+3=2(-4x+7)[/tex]
3) Distribute
[tex]-9x+3=-8x+14[/tex]
4) Subtract 3 from both sides of the equation
[tex]-9x+3-3=-8x+14-3[/tex]
5) Simplify
A. Subtract the numbers
[tex]-9x=-8x+14-3[/tex]
B. Subtract the numbers
[tex]-9x=-8x+11[/tex]
6) Add 8x to both sides of the equation
