Answer:

-1

Step-by-step explanation:

y = mx + c

m is the slope/gradient

to find slope = y2 - y1 / x2 - x1

= -8 - -10 / 4 - 6

m = -1

Answer:

Raul performed better in the biology test

Step-by-step explanation:

Given

History

[tex]Score = 80[/tex]

[tex]Mean = 70[/tex]

[tex]Standard\ Deviation = 10[/tex]

Biology

[tex]Score = 75[/tex]

[tex]Mean = 70[/tex]

[tex]Standard\ Deviation = 2.5[/tex]

Required

Where did he perform better relative to other students

To do this, we simply calculate the z score in both tests and make comparison.

z score is calculated as thus;

[tex]z = \frac{x - Mean}{SD}[/tex]

For history;

[tex]z = \frac{80 - 70}{10}[/tex]

[tex]z = \frac{10}{10}[/tex]

[tex]z = 1[/tex]

For biology;

[tex]z = \frac{75 - 70}{2.5}[/tex]

[tex]z = \frac{5}{2.5}[/tex]

[tex]z = 2[/tex]

Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test

Answer:

The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]

Option B is correct option.

Step-by-step explanation:

We need to change the mixed number to improper & use KCF to rewrite the question.

The expression is: [tex]3\frac{1}{2}\div\frac{1}{3}[/tex]

First converting mixed fraction into improper fraction

Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2

Solving:

[tex]3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}[/tex]

Using KCF

KCF stands fro Keep it, Change it, Flip it.

It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)

So, our expression will be

[tex]=\frac{7}{2}\times \frac{3}{1}[/tex]

So, The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]

Option B is correct option.

Answer:

90%

Step-by-step explanation:

1. We assume, that the number 5400 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 5400, so we can write it down as 100%=5400.

4. We know, that x% equals 6000 of the output value, so we can write it down as x%=6000.

5. Now we have two simple equations:

1) 100%=5400

2) x%=6000

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=5400/6000

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6000 is what percent of 5400

Answer:

We conclude that:

Step-by-step explanation:

Descartes Rule states that if the terms of a single-variable polynomial with real coefficients are ordered by descending variable exponent, then the number of positive roots of the polynomial is:

Given the function

[tex]f\left(x\right)=x^4-2x^3-4x^2+2x+3[/tex]

So, the coefficients are 1, −2, −4, 2, 3

As can be seen, there are 2 changes.

This means that there are 2 or 0 positive real roots.

To find the number of negative real roots, substitute x with -x in the given polynomial:

[tex]x^4-2x^3-4x^2+2x+3[/tex]  becomes [tex]x^4+2x^3-4x^2-2x+3[/tex]

The coefficients are 1, 2, −4, −2, 3

As can be seen, there are 2 changes.

This means that there are 2 or 0 negative real roots.

Therefore, we conclude that:

Answer:

y=-5/3x+1

Step-by-step explanation:

The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down.  We can also assume that the y-intercept is 1 based on where the slope is placed.

Answer:

2/35

Step-by-step explanation:

fifteen total, 4 live in Gaston

so

4/15 times 3/14

because there is only 14 left to be selected and 3 left in Gaston

so 0.05714285714

or 2/35

Answer:

Perpendicular slope = – 1/m = -1/3 = -1/3

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-1\right)[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]

[tex]m=3[/tex]

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 3

perpendicular slope = – 1/m = -1/3 = -1/3

Thus, the slope of any line perpendicular to GH = -1/3

Answer:

12%

Step-by-step explanation:

Original = $874,990

New = $769,991

874,990 - 769,991/874,990

104,999/874,990

0.12

Turn to percentage

Answer:

12%

Step-by-step explanation:

Given:

Percent change formula

[tex]\sf percent\:change=\left|\dfrac{final\:value-initial\:value}{initial\:value} \right|\times 100[/tex]

Substitute the given values into the formula:

[tex]\begin{aligned}\implies \sf percent\:decrease & = \sf \left|\dfrac{769991-874990}{874990} \right|\times 100\\& = \sf 0.1200002286 \times 100\\& = \sf 12.00002286... \\& = \sf 12\% \end{aligned}[/tex]

Therefore, the Percent of Decrease (markdown) to the nearest percent is 12%.

Answer:

6x3+10x2−16x or A

Step-by-step explanation:

I used an algebra calculator because im too lazy to work it out.  

^algebra^

(3x2 + 8x)(2x − 2)

=3x²(2x-2)

=6x³ - 6x²

+8x(2x - 2)

=16x² - 16x

put it all together

=6x³ - 6x² + 16x² - 16x

group according to variables, then count

6x³ + (-6x² + 16x²) - 16x

=6x³ + (+10x²) - 16x

=6x³ + 10x² - 16x
