There are 12 bags of apples on a market stall. The number of apples in bag 12 is 96.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
It is Given that, there are 12 bags of apples on a market stall.
The mean number of apples in each bag is 8.
We need to calculate the number of apples in the 12 bags.
The mean of "n" observations is given as
Mean = Sum of observations/the number of observations
8 = sum of observations/12
The total number of apples = 8 x 12 = 96
Hence, there are 96 apples in 12 bags.

x=5
Step-by-step explanation:
2x+10=20
-10 -10
2x=10
then divide both sides by 2
x=5
Answer:
x = 5
Step-by-step explanation:
Given
2x + 10 = 20
Subtract 10 to both sides
(2x + 10) -10 = 20 - 10
2x = 10
Divide both sides by 2

x=5
Check your work. Substituted 5 for x
2x + 10 = 20
2(5) + 10 =20
10 + 10 = 20
20 = 20

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(5x)?
Answer:
Step-by-step explanation:
If the parent function is f(x) = x² and the transformed function is g(x) = a(x)²
For a > 1, then the transformed function g(x) will be vertically stretched by a factor of 'a'
For 0 < a < 1, then the transformed function will be vertically compressed or shrink by a factor of 'a'
For a function f(x) = x² when transformed to f(5x) = (5x)²
g(x) = 25x²
Therefore, graph of the parent function f(x) will be vertically stretched by 25 units.

For their twentieth wedding anniversary, Richard and Sylvia had a party for several of their best friends. Things were going along just fine until one of their friends asked the happy couple who was older! Here's what they had to say. Richard: "I am older than my wife." Sylvia: "I am younger than my husband." That might have been the end of it, but one of the guests knew that at least one member of the couple was lying. Well, who is older, Richard or Sylvia?
Answer:
Richard is older
Step-by-step explanation:
We can set up an inequality for both statements.
Let r equal Richard's age and s equal Sylvia's age.
"I am older than my wife."
Since Richard is speaking, the inequality would look like this:
r > s
This means Richard is older than Sylvia.
"I am younger than my husband."
Since Sylvia is speaking, the inequality would look like this:
s < r
This means that Sylvia is younger than Richard.
We can flip one inequality to "see" them from the same perspective.
Let's use s < r
To make it so that we can see the relationship from Richard's perspective, flip the entire inequality.
s < r
to
r > s
The inequality from the first quote is identical to this one!
Therefore, Richard is older than Sylvia.

In a large harbour there are many docks, labeled alphabetically, which are built side by side in a straight line. Dock A and Dock K are located 2.3 km apart along this line. There is a Dock L on an island outside the harbour such that is 45° and is 64°. How far is the island dock away from each of the other two docks?
Answer:
distance island dock to Dock A = 4.99 km
distance island dock to Dock K = 6.35 km
Step-by-step explanation:
Always make a scetch to visualize the situation.
You need to construct two triangle both with a streight angle, so you can use Pythagoras to calculate the unknown distances between the island dock L, and each of the other two docks A an K.
I chose to introduce an extra letter, the letter C. In total you have the letters A K L and the letter C.
The letter C has a streight angle of 90° between ACL and it has the same streight angle of 90° with KCL. It is crucial that you see that the distance of LC is exactly the same in triangle LAC and that LC has exactly the same distance in the other triangleLKC.
The distance between AK = 2.3 km.
I define the distance between K and point C as 2.3 + x, because the distance x is unknown.
KC = 2.3 + x
Further more, when you make a picture, you can see that the distance between A and point C = x.
From such a picture, it would show clearly, that K is further away in respect to L then point A. From the picture it would be clear that the angle of LKC is smaller then the angle of LAC, so LKC = 45° and LAC = 64°.
Because angle LKC = 45° and we choose C to have an angle of 90°, the TRIANGLE LKC must be a special triangle... In any triangle, the sum of the three angles together, must add up to 180° .
If that is true, then we have 45 + 90 + 45 (because that adds up to 180). Now that means triangle LKC must have two equal sides (because of the same angels of 45° ).
So we know the distance KC = LC and we already defined KC = 2.3 + x.
Now we know enough to solve the problem.
AK = 2.3 km
angle of LKC = 45°
angle of LAC = 64°
AC = x
KC = 2.3 + x
LC = KC
LC = 2.3 + x
Try to calculate the distance x by using tan. After that you can use Pythagoras to find the other distances.
tan(LKC) = ( LC ) / ( KC )
tan(LKC) = ( x+2.3 ) / ( x+2.3 )
That is not helpful. Let's try the other triangle...
tan(LAC) = LC / AC
tan(LAC) = ( x+2.3 ) / x
tan(64) = ( x+2.3 ) / x
Solve the equation which means you try to find the value for x.
x * tan(64) = ( x+2.3 )
tan(64) * x -x = 2.3
tan(64) * x - 1* x = 2.3
Try to get x outside of the braquets...
x* ( tan(64) - 1 ) = 2.3
x* (2.0503038415793 - 1 ) = 2.3
1.0503038415793 * x = 2.3
x = 2.3 / 1.0503038415793
x = 2.19
Now use Pythagoras a² + b² = c² in triangle LAC to find distance LA.
LA² = AC² + LC²
AC = x = 2.19
LC = 2.3 + x = 4.39
LA² = 2.19² + 4.39²
LA = SQRT( 4.79 + 20.16 )
LA = SQRT( 24.95 )
LA = 4.99 km
Now use Pythagoras a² + b² = c² in triangle LKC to find distance LK.
LK² = KC² + LC²
KC = 2.3 + x = 4.39
LC = 2.3 + x = 4.39
LK² = 4.39² + 4.39²
LK = SQRT( 20.16 + 20.16 )
LK = SQRT( 40.32 )
LK = 6.35 km
Phillip is rolling two number cubes. How many different ways can he roll the number cubes and get a sum of 6?
A. 3
B. 4
C. 5
D. 6
We will find that there are 5 outcomes where the sum of the numbers on the dice adds up to 6.
In how many different ways can he roll a sum of 6?We want to see how many outcomes are there where the sum of the two dice is equal to 6. Each dice has 6 outcomes, which are:
{1, 2, 3, 4, 5, 6}
For rolling two dice with 6 outcomes each, the total number of outcomes is:
6*6 = 36
For rolling two dice, we can use the notation:
dice 1, dice 2
And we can also write the sum, so we will only look at the outcomes where the sum is 6.
dice 1, dice 2, Sum
1 5 1 + 5 = 6
5 1 5 + 1 = 6
2 4 2 + 4 = 6
4 2 4 + 2 = 6
3 3 3 + 3 = 6
So there are 5 outcomes where the sum is equal to 6, so the correct option is B

What is the mean daily pocket money?
*diagram of the dot plot is attached below
Answer:
$2.15
Step-by-step Explanation:
Mean daily pocket money or average daily pocket if the group if students shown in the for plot that is attached below = the sum of the pocket money received by the students ÷ the total number of students.
From the diagram of the dot box attached below, the total number if students = 13 (each dot represents a student)
Sum of the pocket money received by the students = 4(1) + 5(2) + 3(2) + 4(2)
= 4 + 10 + 6 + 8
Sum = 28
Therefore, mean daily pocket money = 28 ÷ 13 = $2.15

Answer: 33
Step-by-step explanation:
there ages m and b.
m = b + 12
m - 17 = 4(b - 17) m = 4b - 51
3b = 63
b = 21
m = 21 + 12 = 33
Hope this helps :)
Answer: Michael is 33 years old.
Step-by-step explantation: Okay, think of it like this, Michael's age for right now is x since we still do not know Michael's age. Pay close attention to the first sentence. What does it say? m = b + 2. Now pay attention to the second sentence. What does it say? m - 17 = 4 ⋅ (b = 17). Now, let's move on to the system of equations. As you can see here, the system of equations is
{m = b + 12
{m - 17 = 4 ⋅ (b - 17}.
Now for more equations.
m - 17 = 4b - 68
m = 4b - 68 + 17
m = 4b - 51
m - 4b = -51
-
b + 12 - 4b = -51, through the substitution from the first equation we saw
-3b = -51 - 12
3b = 51 + 12
b = 51/3 + 12/3
b = 17 + 4
b = 21
-
m = 33.

h(t) = -16ť? + 20+ + 30
where t is time in seconds.
How long does it take for the ball to hit the ground?
Question to answer: How long does it take for the ball to hit the ground? Round to the nearest tenth.
The ball hits the ground at
seconds.
Answer:
2 seconds
Step-by-step explanation:
When the ball hits the ground, its height (h) will be 0. You can therefore set up the following equation:
[tex]0=-16t^2+20t+30 \\\\-4(4t^2-5t-6)=0[/tex]
Factor:
[tex]-4(4t+3)(t-2)=0 \\\\t=-\dfrac{3}{4}, 2[/tex]
