What is a standard deviation?
A standard deviation is a measure of how dispersed the data when compared to the mean.
In this case, the standard deviation will stay the same as it is not affected by a change in a single measurement. Therefore, the change will not affect the standard deviation of the set of student ages.

What is the equation of the line that passes through the point (4,6) and has a
slope of 0
Solution:
We know that:
(x,y) = (4,6) ⇒ x = 4, y = 6Slope = 0Since we know the coordinates and the slope of the line, we can use point slope form to find the equation.
y - y₁ = m(x - x₁)⇒ y - 6 = 0(x - 4)⇒ y - 6 = 0⇒ y = 0 + 6⇒ y = 6Thus, the equation of the line is y = 6.
Answer/Step-by-step explanation:
Given us that;
Passes through the point (4,6)
slope of 0
Note;
The equation of a line has the form:
y - y₁ = m(x - x₁)
Solve;
Now we plug in the coordinates of the given point the line goes through, and solve:
y - 6 = 0(x - 4)
y - 6 = 0
y = 0 + 6
y = 6
Hence, equation of the line is y = 6

Answer:
a=(x+7)(x+-2)
Step-by-step explanation:
(x+a)(x+b)=x²+(a+b)x+(ab)
Answer:
a) (x +7)(x -2)
b) x = -7 or +2
Step-by-step explanation:
a)A trinomial is factored by realizing that the constant term (-14) is the product of the binomial constants, and the coefficient of the linear term (5) is their sum. Here, we can examine the factorization of -14 to see which factors may have a sum of 5:
-14 = (-1)(14) = (-2)(7) = (-7)(2) = (-14)(1)
Sums of these factor pairs are 13, 5, -5, -13. Clearly, we could stop writing factorizations when the sum stops being positive. The values of interest are -7 and 2. They tell us the trinomial is factored as ...
x² +5x -14 = (x +7)(x -2)
__
b)The zeros of the quadratic are the values of x that make the above factors be zero. The zero product rule tells you the only way the product will be zero is for a factor to be zero.
x +7 = 0 ⇒ x = -7
x -2 = 0 ⇒ x = 2
The solutions are x = -7 or x = 2.

The graph below describes the journey of a train between two cities.
a) Work out the
acceleration, in km/h?,
in the first 15 mins.
b) Work out the distance
between the two cities. $60
Velocity (in km/h)
c) Work out the average
speed of the train during 20
the journey.
Answer:
[A] Acceleration in first 15 min = 200 km/h²
[B] Distance between two cities = 125 km
[C] Average Speed of journey = 62.5 km/hr
Step-by-step explanation:
To Solve:
Acceleration in first 15 min
Distance between two cities
Average speed of journey
Solve:
[A] Work out the acceleration, in km/h?, in the first 15 mins.
Each horizontal block is 1/8 hr = 7.5 min
Each vertical block is 10 km/hr
Time Velocity km/hr
0 Min ( 0 hr) 0
15 Min (1/4 hr) 50
45 Min (3/4 hr) 50
60 MIn ( 1 hr) 100
90 Min ( 3/2 hr) 100
120 Min ( 2hr) 0
Acceleration in first 15 min (1/4 hr) = (50 - 0)/(1/4 - 0) = 50/(1/4)
= 200 km/h²
Hence, Answer for [A] = 200 km/h²
[B] Work out the distance between the two cities. $60 Velocity (in km/h)
= (1/2)(0 + 50)(1/4 - 0) + 50 * (3/4 - 1/4) + (1/2)(50 + 100)(1 - 3/4) + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)
= 25/4 + 25 + 75/4 + 50 + 25
= 125
Distance between two cities = 125 km
[C] Work out the average speed of the train during 20 the journey.
Average Speed of journey = 125/2 = 62.5 km/hr

If you want to sell your cupcakes for $2 per dozen, you can make a profit of $160. If raise the cupcake price by
$1, you can make a profit of $216. If you raise the cupcake price by $2 (which makes them S4 per dozen) you can
make $256 profit. What is the maximum profit you can make? What should you charge for your cupcakes?
The maximum profit is $288, and you should charge $6 per dozen.
How to get the relation between demand and prize?
Let's assume that demand depends linearly on price, such that we can write:
q = a*p + b
where q is the demand and p is the price.
We have 3 points of that line:
When you sell at $2 per dozen, you win $160, so you sold 80 dozens.When you sell at $3 per dozen, you win $216, so you sold 72 dozens.When you sell at $4 per dozen, you win $256, so you sold 64 dozens.The slope of the line is given by:
[tex]a = \frac{q_2 - q_1}{p_2 - p_1}[/tex]
Where these are values of demand and prize for two different points, if we use the first two points we get:
[tex]a = \frac{72 - 80}{3 - 2} = -8[/tex]
Then the line is something like:
q = -8*p + b
Remember that when p = 2, the demand is equal to 80, replacing that we get:
80 = -8*2 + b
80 + 16 = b = 96.
So the line is:
q = -8*p + b
How to maximize the profit?Profit is given by the product between the demand and the price, so we have.
Profit = p*q = p*(-8*p + 96) = -8p^2 + 96p
We want to maximize that, notice that is a quadratic equation of negative leading coefficient, so the maximum is at the vertex, using the equation for the vertex of a quadratic equation we will see that the maximum is at:
p = -96/(2*-8) = 6
Then the maximum profit is:
profit = -8*(6)^2 + 96*6 = 288
The maximum profit is $288, and you should charge $6 per dozen.

The sum of the measures of angle A and angle B is 90°
• The measure of angle A is (4x + 30)
The measure of angle B is (40)
What is the value of x?
Answer:
x = 5
Step-by-step explanation:
Given:
The sum of the measures of angle A and angle B is 90° The measure of angle A is (4x + 30)The measure of angle B is (40)To Find:
What is the value of x?
Note:
Two angles that add up to give you 90° is a complementary angle.
Thus, Since angle A and angle B sum up to give 90°, they are complementary angles.
Solve:
The following equation can be created to solve for the value of x:
m ∠A + m∠ B
Substitute
40 + 4x + 30 = 90
Add like terms
4x +70 = 90
Subtract 70 from both sides
4x = 90-70
4x = 20
Divide both sides by 4
x = 5
Therefore, the value of x is 5

The y-intercept of g(x)=3/5f(5x) is 15.
Which of the following is the y-intercept of f(x) ?
A/ 3
B/9
C/25
D/75
Answer:
C) 25
Step-by-step explanation:
A function is scaled vertically by multiplying every function value by the scale factor. For some scale factor k, the function g(x) = k·f(x) is a vertically scaled version of the function f(x).
Here, we are given ...
g(x) = 3/5·f(x)
This means the y-intercept is also scaled:
g(0) = 3/5·f(0)
f(0) = 5/3·g(0) . . . . . multiply by 5/3
f(0) = 5/3·15 = 25
The y-intercept of f(x) is 25.
