The remainder that is found when dividing 2x^2+7x-4 by x-3 is 35
Calculating the remainder that is found when dividing 2x^2+7x-4 by x-3?From the question, we have the following parameters that can be used in our computation:
Dividing 2x^2+7x-4 by x-3
This means that
Dividend = 2x^2 + 7x - 4
Divisor = x - 3
Set the divisor to 0
So, we have
x - 3 = 0
Evaluate
x = 3
Substitute 3 for x in the dividend equation, so, we have the following representation
Remainder = 2(3)^2 + 7(3) - 4
Evaluate
Remainder = 35
Hence, teh remainder is 35

On this problem, the answer has been worked out, but you must fill in the blanks in the solution.A random sample of 450 students from a wide geographical area indicated that 55 attended private schools. Estimate the true proportion of students attending private schools with 95% confidence. Give your answer to three places after the decimal point.Solution: We need to find the 95% confidence interval for the proportion (p).
State the parameters given in the question
\(n=450\)The sample size n is 450
Hence, the first box n=450
\(X=55\)The number of students X that attended private school is 55
Hence, the second box X=55
Therefore, sample proportion is
\(\begin{gathered} ^{\prime}p=\frac{X}{n}=\frac{55}{450} \\ ^{\prime}p=0.122 \end{gathered}\)Hence, the third box is 'p=0.122
\(\begin{gathered} ^{\prime}q=1-^{\prime}p \\ ^{\prime}q=1-0.122 \\ ^{\prime}q=0.878 \end{gathered}\)Hence, the forth box is 'q= 0.878
From the question, the confidence interval is 95% can be represented as
\(\begin{gathered} z_{\alpha I2}=95\text{ \%=0.95} \\ \alpha=1-0.95=0.05 \\ \alpha I2=\frac{0.05}{2}=0.025 \end{gathered}\)The Z score for confidence interval of 95% is gotten from the table as 1.96
The formula for the confidence interval for p is
\(^{\prime}p-z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}Substitute into the formula
\(\begin{gathered} ^{\prime}p-z_{\alpha I2}z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}} \\ ^{\prime}p=0.122;^{\prime}q=0.878;z_{\alpha I2}=1.96 \\ =0.122-1.96_{}\sqrt[]{\frac{0.122\times0.878}{450}} \\ =0.122-1.96\sqrt[]{\frac{0.107116}{450}} \\ =0.122-1.96\sqrt[]{0.0002380356} \\ =0.122-1.966(0.015428) \\ =0.122-0.03024 \\ =0.09176 \\ =0.092(3\text{ decimal places)} \end{gathered}\)\(\begin{gathered} z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}\text{was calculated to be 0.03024} \\ \text{Therefore} \\ ^{\prime}p+z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}=0.122+0.03024=0.15224 \\ =0.152(3\text{decimal places)} \end{gathered}\)Hence, the confidence interval is 0.092

This is the final static variable for all instances.
That makes the behaviour much more obvious. Modern IDEs will usually suggest changing the second listing into the third.
There is no reason to have an inline declaration initializing the value like the following, as each instance will have its own NUMBER but always with the same value. This is the same than to have only one final static variable for all instances.
The static keyword means the value is the same for every instance of the class. The final keyword means once the variable is assigned a value it can never be changed. The combination of static final in Java is how to create a constant value.

salesperson earns $345 for selling $2300 in merchendice find the commison rate
Answer:
The commission rate is 15%
Step-by-step explanation:
commission = commission rate x sales
where the commission rate is expressed as a decimal.
In this case, the salesperson earned a commission of $345 for selling $2,300 in merchandise. Therefore, we have:
345 = commission rate x 2300
To solve for the commission rate, we can divide both sides by 2300:
commission rate = 345/2300
Simplifying this expression, we get:
commission rate = 0.15
So, the commission rate is 15%

Write an equation of the line passing through the point (8, -5) that is parallel to the line 2x -6y = -3
Answer:
y=1/3x+10.5
Step-by-step explanation:
y=mx+b, the equation of the parallel line is y=1/3x+1/2. So we know the slope is 1/3 and all we need is the Y intercept (b). We can find that manually with arithmetic because we know the slope. It turns out to be 10.5
the length of a rectangle is twice its width. if the perimeter of the rectangle is 54m find its area
Answer:
You can denote the width of the rectangle as x,
than the length of the rectangle will be 2x
and the perimeter of the rectangle will be two length plus two width and it should be equal to 54 in
and the equation will look 2(2x)+2x=54
solving the equation 6x=54, x=9in
So the width of the rectangle is 9in and the length is 9*2=18in
and the area of the rectangle is 9*18=162 sq in.
For which product or quotient is this expression the simplest form? (image attached)! please help :((
Answer:
D
Step-by-step explanation:
For simplify the work we can start to factorise all the possibles expressions:
2x + 8.
8 is multiple of 2, so it can became
2(x+4)
x^2 - 16 this is a difference of two squares, so it can be rewritten as:
(x+4)(x-4)
x^2 + 8x + 16
we have to find two numbers whose sum is 8 and whose product is 16
the two number are 4 and 4
it becames:
(x+4)(x+4)
x+ 4 can‘t be simplified
if we look at the expression, we can find that x-4 appears at the numerator so
x^2 - 16 must be at numerator
but the second factor (x+4) doesn’t appear, so has been simplified. This situation can be possible only in the D option
in fact
(x+4)(x-4)/2(x+4) * (x+4)/(x+4)(x+4)
it became
(x+4)(x-4)/2 * 1/(x+4)(x+4)

David found a vintage watch his father lost 38 years ago. The watch’s date showed that it had worked for over two years after his father lost it. When David found the watch, it was 3 times as old as when his father lost it. How old was the watch when David’s father lost it?
Answer:
Step-by-step explanation:
Hey there,
Here's my reasoning regarding the problem:
Let's assume that the watch at the time it was lost was x years old.
When it was picked it was 3 times as old as it was when it was lost therefore it's currently 3x. The time between when it was lost and when it was found is 38 years. We can break this down into a simple algebraic formula:
3x - x = 38
2x = 38
x = 19

The perimeter formula and the given relation between length and width can be used to write and solve an equation for the field dimensions.
SetupLet w represent the width of the field. Then (3w-120) is the length of the field, and its perimeter is ...
P = 2(L +W)

Rotation of a quarter circle to form an hemisphere, by integration is presented as follows;
\(\int\limits^1_0 \pi \times ({\sqrt{1-x^2} })^2 \, dx = \frac{2}{3} \cdot \pi\)
The volume of the cone carrying the hemisphere = (1/3)×π×1²×4 = (4/3)·π
The volume of the ice cream = The volume of the cone + The volume of the hemisphere
Therefore;
Volume of the ice cream = (2/3)·π + (4/3)·π = (6/3)·π = 2·π ≈ 6.3
The volume of the ice cream ≈ 6.3 cubic inches(b) Volume of ice cream contained in the new ice cream cone, V = 14.5 cubic inches
The formula for the volume of the ice cream, V = (2/3)·π·r³ + (4/3)·π·r²
Therefore;
V = (2/3)·π·r³ + (4/3)·π·r² (substitution property)
V = (2/3)·π·r³ + (4/3)·π·r²
14.5 = (2/3)·π·r³ + (4/3)·π·r²
