The point (12,489) will be the solution of our given equations.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
number of men given by y=3.9x+441 ,
and for women equation is y=14.3x+312,
Now, Let us find the coordinates of the point of intersection of both lines by equating our both equations as:
3.9x+ 441 = 14.3x + 312
14.3x - 3.9x = 441 - 312
10.4x= 129
x= 129/10.4
x = 12.40
and, y= 3.9(12.4)+ 441
y= 489.36
Hence, the point (12,489) will be the solution of our given equations.

Answer: Answer choice B
Step-by-step explanation:
Graph the equation. y = -(x-4)^2+4
f(x) = 3x² + 2x - 20 for x = 3
help please?
When we're given f(x) and x, we can evaluate the function by replacing every x with the given value, and simplifying.
Solving the Question[tex]f(x) = 3x^2 + 2x - 20[/tex]
⇒ Replace every x with 3:
[tex]f(3) = 3(3)^2 + 2(3) - 20\\\\f(3) = 3(9) + 6 - 20\\\\f(3) = 27 + 6 - 20\\\\f(3) = 13[/tex]
Answer[tex]f(3) = 13[/tex]
Step-by-step explanation:
A function is a relationship bound to one output for every single input the value of F(3) for the given function F(x)=3x²+2x-20 is 13.
What is a function?
The function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
A certain kind of relationship called a function binds inputs to essentially one output.
As per the given function,
F(x)=3x²+2x-20
Substitute, x = 3
F(3) = 3(3)^2 + 2(3) - 20
F(3) = 3(9) + 6 - 20
F(3) = 13
Hence "A function is a relationship bound to one output for every single input the value of F(3) for the given function F(x)=3x²+2x-20 is 13".

solve -x+y=6 and 2x+5y=-12 using substitution method
x=-6 and y=0 are solutions for the equations 2x+5y=-12.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given equations,
-x+y=6...(1)
2x+5y=-12 ...(2)
From equation 1
y=6+x
Now put y value in 2
2x+5(6+x)=-12
2x+30+5x=-12
7x+30=-12
Subtract 30 on both sides
7x=-12-30
7x=-42
Divide both sides by 7
x=-6
Now plug in x value in equation 1
-(-6)+y=6
6+y=6
y=0
Hence, x=-6 and y=0 for the equations 2x+5y=-12.

Sandpiper Company has 25,000 shares of cumulative preferred 1% stock, $150 par and 50,000 shares of $5 par common stock. The following amounts were distributed as dividends:
20Y1 $75,000
20Y2 15,000
20Y3 112,500
Determine the dividends per share for preferred and common stock for each year. Round all answers to two decimal places.
If Sandpiper Company has 25,000 shares of cumulative preferred 1% stock.
Dividends per share for preferred
Year 1 = $3 per shareYear 2 = $4.5 per shareYear 3 = $1 per shareCommon stock
Year 1 = $0Year 2 = $1.95Year 3 =$1.75How to find the dividends per share and common stock?The arrear $75,000 of unpaid dividends from year 1 will be paid to preferred stockholders in year 2
= ($150 x 1% x 25,000) +$75,000
= ($37,500 + $75,000)
= $112,500
Year 1 Year 2 Year 3

Preferred $75,000 $112,500 $25,000
Common $0 $97,500 $87,500
Dividends per share for preferred
Year 1 = $75,000/25,000 shares
Year 1 = $3 per share
Year 2 = $112,500 /25,000 shares
Year 2 = $4.5 per share
Year 3 = $25,000/$25,000 shares
Year 3 = $1 per share
Common stock
Year 1 = 0/ 50,000 shares
Year 1 = $0
Year 2 =$97,500 / 50,000 shares
Year 2 = $1.95
Year 3 = $87,500 /50,000 shares
Year 3 =$1.75
Therefore the dividends per share for preferred is $3 per share, $4.5 per share, $1 per share and the common stock $0, $1.95, $1.75.

The quadratic function that models the graph on the image is given as follows:
y = (x - 1)² - 1.
What is the quadratic function?The features of the quadratic equation given from the graph are given as follows:
The vertex.The y-intercept.The equation of a quadratic function with vertex (h,k) is defined as follows:
y = a(x - h)² + k.
In which a is the leading coefficient of the function.
From the graph, the coordinates of the vertex are given as follows:
(1,1).
As the vertex is the turning point of the function.
Hence the parameters h and k have values of:
h = 1, k = 1.
Hence:
y = a(x - 1)² + 1.
The y-intercept of the function is of:
y = 2.
This means that when x = 0, y = 2, hence the leading coefficient a is obtained as follows:
2 = a(0 - 1)² + 1
a = 1.
Hence the equation is of:
y = (x - 1)² - 1.

a) The dot plot of the data-set is given by the second image shown at the end of the answer.
b - i) The mean of the distribution is of: 1.6 goals.
b - ii) The median of the distribution is of: 1.
b - iii) The mode of the distribution is of: 1 goal.
What are the measures?The mean is given by the sum of all observations of the data-set, hence it is of:
Mean = (0 x 5 + 1 x 6 + 2 x 4 + 3 x 3 + 4 x 1 + 5 x 1)/20 = 1.6.
The median of the distribution is the middle value of the distribution, which is the value of which half the distribution is less than and half is greater than.
Adding in the frequency table given at the end of the answer, it is found that the middle term is of 1, as the sum of the frequencies reaches 10, which is half of the cardinality of 20, at a number of 1.
The mode is the term with the highest absolute frequency, hence it is also of one goal, as it has the highest absolute frequency, which is of 6.
The dot plot gives a dot to each measure for each time that it appears, hence it says the same thing as the table, in a different format.

Assume that all distributions are normal, the
four population standard deviations are
approximately the same, and the data were
collected independently and randomly. Use a
level of significance of 0.05.
By using the concept of mean and standard deviation, it can be inferred that
The the drug stays in the system for more than 397 minutes
What is mean and Standard Deviation?
Suppose there is a data set and the average of the data set has to be calculated. To calculate the average of the data set, mean is used
To know about Standard Deviation, it is important to know about Variance
Variance is the sum of the square of deviation from mean.
Square root of the variance gives the standard deviation
Given n = 35,
Population mean = 397
Population Standard Deviation = 18
Here the sample size is large. So the distribution is approximately normal
To test :
Test statistic t =
= 1.97
p value at = 0.0244
Since 0.0244 < 0.05, the null hypothesis is rejected
So the the drug stays in the system for more than 397 minutes

Find the HCF of 2, 4 and 4/5.
(A) 1/20 (B) 1/40 (C) 20 (D) 15
Answer:
1/20
Step-by-step explanation:
You can find the HCF (Highest Common Factor), also known as GCF, by dividing the numbers by the list of answers. And, if they all come out as whole numbers, then the answer you chose will be the answer. But, if there is another answer that also comes out as whole numbers for all of them, we choose the biggest one (HCF):
2 ÷ 1/20 = 40
4 ÷ 1/20 = 80
4/5 ÷ 1/20 = 16
So, 1/20 is definitely one of the answers, but we should check the other ones too:
2 ÷ 1/40 = 80
4 ÷ 1/40 = 160
4/5 ÷ 1/40 = 32
So, even though we also got whole numbers for this one, it isn't the answer because 1/20 is bigger than 1/40 so far. Let's try the last two answers:
2 ÷ 20 = 0.1
So, we already got our answer. We don't need to check the rest of the numbers, because the first one is already not a whole number. Let's try the final answer:
2 ÷ 15 = 0.13333333
This is not the right one either. So, our answer is 1/20 because it is the biggest one that came out as all whole numbers.

m = 5/4
x = 2 from the point (2,-1)
y = -1 from the point (2,-1)
y = mx + b
-1 = [tex]\frac{5}{4}[/tex] ([tex]\frac{2}{1}[/tex]) + b
