Find the mean from the following obtained marks of the student after constructing a frequency distribution table .
1,5,6,9,8,4,1,9,8,4,5,4,5,6,5,4,1,5,4,6
Mean = 8
The mean is the average number in a sequence. To find the mean we can simply use the following equation
(Sum of all numbers) ÷ (Amount of numbers)
The sum of the given numbers is 160
The amount of numbers is 20
So the mean = 160 ÷ 20 or 8.
Alex has a pile of 2p coins. She swapped exactly half of them for the same number of 10p coins.
Now she has £4.20
How much money did alex have initially?
Answer:
£8.4
Step-by-step explanation:
Since she swapped half and now has £4.20, then multiply that by 2
4.20 × 2 = 8.4
Alex initially had £8.4
The initial amount of Alex's 2p coins is £8.40
Let the initial worth of 2p coins = y
Half of y = y/2 The value of y/2 = £4.20The amount of money Alex had initially = yWe can then solve for the worth of y, which is the titla amount Alex had initially ;
y/2 = £4.20Multiply bith sides by 2 (y/2)×2 = £4.20 × 2 y = £8.40Therefore, the amount of money Alex had initially is £8.40

Answer:
x = 24°
Step-by-step explanation:
here's your solution
=> measure of angle 1 = (6x)°
=> measure of angle 2 = (x + 12)°
=> we know that The sum of angles on a straight line is equal to 180°
=> so, (6x)° + (x + 12°) = 180°
=> 7x + 12° = 180°
=> 7x = 180° - 12°
=> 7x = 168°
=> x = 168°/7
=> x = 24°
=> angle 1 = 24°×6 = 144°
=> angle 2 = 24° + 12 = 36°
hope it helps 【◆◆】
Answer:
∠ 1 = 144°, ∠ 2 = 36°
Step-by-step explanation:
∠ 1 and ∠ 2 are adjacent angles and sum to 180° , that is
6x + x + 12 = 180
7x + 12 = 180 ( subtract 12 from both sides )
7x = 168 ( divide both sides by 7 )
x = 24
Then
∠ 1 = 6x = 6(24) = 144°
∠ 2 = x + 12 = 24 + 6 = 36°

Step-by-step explanation:
You need to translate all the points to the right 3 and up 6
Therefore, you are going to use this formula:
(x,y) ⇾ (x + 3, y + 6)
This is the same format as the previous problem, if you have noticed.
Using this, plug in each coordinate, starting with P (5, -1)
(5, -1) ⇾ ( 5 + 3, -1 + 6)
(5, -1) ⇾ ( 8, 5 )
P[tex]^{1}[/tex] = (8, 5)
Now point Q, (0, 8)
(0, 8) ⇾ (0 + 3, 8 + 6)
(0, 8) ⇾ ( 3, 14 )
Q[tex]^{1}[/tex] = (3, 14)
And last but not least, the point R, (7, 5)
(7, 5) ⇾ (7 + 3, 5 + 6)
(7, 5) ⇾ ( 10, 11 )
R[tex]^{1}[/tex] = (10, 11)
Therefore, P[tex]^{1}[/tex] = (8, 5), Q[tex]^{1}[/tex] = (3, 14), R[tex]^{1}[/tex] = (10, 11) is your answer. This is the 4th option or D.
Hope this for you to understand this a bit more! =D

Which number line shows all the values of x that make the inequality -3x+1<7
true?
Answer:
D
Step-by-step explanation:
Firstly, we need to get the value of x 1-7 < 3x
-6 < 3x
-2 < x
or x > -2
So we need a number line that has the unshaded circle placed at 2 ( since the inequality sign is single) and it faces the right (arrow face right)

Abel is 12 years old and Gino is 8. They share 15 apples in the ratio of their ages. How many does each get?
Answer:
Abel gets 9 apples while Gino gets 6 apples.
Step-by-step explanation:
Total age = 20 (Abel's age =12 + Gino's age =8)
Abel's share =
[tex] \frac{12}{20} \times \frac{15}{1 } = 9[/tex]
Gino's share =

Determine the volume of the rectangular prism.
Answer:
50 ft³Step-by-step explanation:
We know the formula for a rectangular prism is length × width × height
We also know all the sides so we can rewrite the formula replacing variables.
The length is 8, the width is 2[tex]\frac{1}{2}[/tex] and the height is 2[tex]\frac{1}{2}[/tex]
8 × 2[tex]\frac{1}{2}[/tex] × 2[tex]\frac{1}{2}[/tex]
Multiply which ever way is easy for you. I am just multiplying from left to right.
8 × 2[tex]\frac{1}{2}[/tex] = 20
20 × 2[tex]\frac{1}{2}[/tex] = 50
Now we get 50. Before we put our answer as 50, there are two more steps.
First we need to add the measurement unit which is feet or ft
We also need to add ³ since it is volume
50 ft³ is our final answer
Order the following expressions by their values from least to greatest
Answer:
Step-by-step explanation:
a = -1
b = 2
c = 3
a + (-c) = -1 + (-3) = -4
Both numbers have same sign(-Ve).So add and the result will have the -Ve sign.
c - (-b) = c + b = 3 + 2 = 5
b = 2
Least to greatest: a +(-c) , b , c-(-b)

A, B & C lie on a straight line. D, C & E lie on a different straight line. Angle y = 117° and angle z = 63°. Work out x
Consider the below figure attached with this question.
Given:
A, B & C lie on a straight line. D, C & E lie on a different straight line.
[tex]\angle y=117^\circ,\angle z=63^\circ[/tex]
To find:
The value of x.
Solution:
A, B & C lie on a straight line.
[tex]m\angle ABD+m\angle DBC=180^\circ[/tex] (Linear pair)
[tex]y+m\angle DBC=180^\circ[/tex]
[tex]m\angle DBC=180^\circ-y[/tex]
According to the exterior angle theorem, the measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.
[tex]m\angle DBC+m\angle BDC=m\angle BCE[/tex] (Exterior angle theorem)
[tex]180^\circ-y+z=x[/tex]
[tex]180^\circ-117^\circ +63^\circ =x[/tex]
[tex]126^\circ =x[/tex]
Therefore, the value of x is 126 degrees.
