It is given that
Present population (P) = 15625
Rate of increase (r) = 4% p.a.
Period (n) = 3 years
We know that
Population after 3 years = P(1+r/100)
n
Substituting the values
= 15625(1+4/100)
3
By further calculation
= 15625×26/25×26/25×26/25
=17576
So the increase = 17576−15625=1951

tell which property of equality was used. 5m + 4 = 19 5m + 43= 19-3.
The value of m from the given equation is 3
Given the expression
5m + 4 = 19
Subtract 4 from both sides using the subtraction law of equality.
5m + 4 - 4 = 19 - 4
5m = 19 - 4
5m = 15
Divide both sides by 5 using the Division law of equality
5m/5 = 15/5
m = 3
Hence the value of m from the given equation is 3

WE have been given that;
Let 4 gallons of water ... 30 plants
Let x gallons of water = ? ... 45 plants
The water will it take to water 45 plants, it can be calculate this using the following steps;
4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water
Therefore, We will use 6 gallons of water to water 45 plants.

Answer:
For the function f(x) = 3x - 8,
f(0) = -8
f(4) = 4
f(-4) = -20
f(1/3) = 7
Step-by-step explanation:
Given:
f(x) = 3x - 8
f(0) = 3(0) - 8
f(0) = 0 - 8
f(0) = -8
f(4) = 3(4) - 8
f(4) = 12 - 8
f(4) = 4
f(-4) = 3(-4) - 8
f(-4) = -12 - 8
f(-4) = -20
f(1/3) = 3(1/3) - 8
f(1/3) = 1 - 8
f(1/3) = 7
A restaurant has an electronic system that randomly selects customers when they pay for their meal to
receive a coupon for their next visit. Each customer has a 10% probability of being selected to receive a
coupon, and one customer being selected or not doesn't affect whether or not another customer will be
selected.
Suppose that 2 customers pay for their meals, one after the other.
What is the probability that NEITHER customer is selected to receive a coupon?
Round your answer to two decimal places.
Show Calculator
Report a problem
Using the binomial distribution, it is found that there is a 0.81 = 81% probability that NEITHER customer is selected to receive a coupon.
For each customer, there are only two possible outcomes, either they receive the coupon, or they do not. The probability of a customer receiving the coupon is independent of any other customer, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.In this problem:
For each customer, 10% probability of receiving a coupon, thus [tex]p = 0.1[/tex].2 customers are selected, thus [tex]n = 2[/tex]The probability that neither receives a coupon is P(X = 0), thus:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{2,0}.(0.1)^{0}.(0.9)^{2} = 0.81[/tex]
0.81 = 81% probability that NEITHER customer is selected to receive a coupon.

The mass of a lorry and its load is 2.87t. What is the mass of the load in kg, if the mass of the lorry is 1.225 tonnes?
a) 1.645kg
b) 1645kg
c) 1225kg
d) 0.001645kg
The mass of the load in kilogram is an illustration of subtraction operation
The mass of the load in kilogram is (b) 1645 kg
The complete mass is given as:
[tex]\mathbf{m_t = 2.87\ tonnes}[/tex]
The mass of the lorry is given as:
[tex]\mathbf{m_l = 1.225\ tonnes}[/tex]
The mass of the load is calculated by subtracting the mass of the lorry from the mass of the lorry and its load.
So, we have the following equation:
[tex]\mathbf{m_{load} = m_t - m_l}[/tex]
Substitute known values
[tex]\mathbf{m_{load} = 2.87\ tonnes- 1.225\ tonnes}[/tex]
Subtract
[tex]\mathbf{m_{load} = 1.645\ tonnes}[/tex]
Convert to kilogram
[tex]\mathbf{m_{load} = 1.645 \times 1000kg}[/tex]
Multiply
[tex]\mathbf{m_{load} = 1645 kg}[/tex]
Hence, the mass of the load in kilogram is (b) 1645 kg

Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(x-11)?
Step-by-step explanation:
f(x) = x
g(x) = f(x - 11)
g(x) = x
g(x) = (x - 11)
g(x) = x - 11
So, g(x) = x - 11

How do you combine like terms to simplify algebraic expressions?
Answer: To combine like terms, we must first understand what they are. Like terms are, well like. An example will make more sense. See the equation 2 + 4x - 5y * 0.2xy. Here, we have no like terms. Why? Because 2 has no variable while 4x has x. However, 4x and 5y don't have the same variable so they are NOT like either. Do not fall into the 0.2xy trap either because that is not like with 4x or 5y. Now that you (hopefully) understand let us try an example.
5x * 2x - 24 = 16
As you can see, the like terms here are 5x and 2x as well as 4 and 16. Now let us simplify by bringing the like terms together.
5x * 2x = 16 + 24
10x^2 = 40 (Be careful here! since we are multiplying x twice it will become x^2)
x^2 = 40/10
x^2 = 4
x = 2 (or -2)
And there you go! You just simplified using like terms.
