Answer:
[tex]n = 7[/tex]
Step-by-step explanation:
Given
[tex]\bar x = 8[/tex] --- the mean
[tex]\sum x = 56[/tex] --- sum of scores
Required
The number of scores (n)
This is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
Make n the subject
[tex]n = \frac{\sum x}{\bar x}[/tex]
[tex]n = \frac{56}{8}[/tex]
[tex]n = 7[/tex]

Answer:
||w|| = 6
Step-by-step explanation:
||w|| = modulus or magnitude of vector w
Since formula to get the modulus of any vector = [tex]\sqrt{\text{(x-component)}^2+\text{(y-component)}^2}[/tex]
Vector w = <-6, 0>
x-component of vector w = (-6)
y-component of vector w = 0
Therefore, ||w|| = [tex]\sqrt{(-6)^2)+(0)^2}[/tex]
= 6
Let $f(x) = x^3 + 3x ^2 + 4x - 7$ and $g(x) = -7x^4 + 5x^3 +x^2 - 7$. What is the coefficient of $x^3$ in the sum $f(x) + g(x)$?
Answer:
6
Step-by-step explanation:
Adding the two polynomials gives
(x^3 + 3x^2 + 4x - 7) + (-7x^4 +5x^3 + x^2 - 7) =
-7x^4 + (x^3 + 5x^3) + (3x^2 + x^2) + 4x + (-7-7) =
- 7x^4 + 6x^3 + 4x^2 + 4x -14
The x^3 term is 6x^3, so the desired coefficient is 6.

FIND EG
Answer:
EG = 7
Step-by-step explanation:
The parallel lines cut sides AB and AC into segments with proportional lengths.
AB/DF = AC/EG
(AD + DF + FB)/DF = AC/EG
(18 + 10 + 12)/10 = 28/EG
40/10 = 28/EG
4 = 28/EG
4EG = 28
EG = 28/4
EG = 7

In ΔKLM, k = 4.4 cm, l = 3.1 cm and ∠M=150°. Find the length of m, to the nearest 10th of a centimeter.
The value of length m is 2.13cm
What is cosine rule?In trigonometry, the Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.
therefore m² = k²+l²+2klCos M
m² = 4.4²+3.1²+ 2× 3.1×4.4cos 150
m² = 19.36+9.61+27.28(-0.8660)
m² = 28.97-23.62
m² = 5.35
m = √5.35
m = 2.31 cm( nearest tenth)
Therefore the measure of length m is 2.31 cm

Where would it go I know how to do X axis but not Y
Answer: (-1,2) and (2,2) Make sure to see explanation!
Step-by-step explanation:
Well you need to remember the Y reflection rule!
To reflect over the Y axis you must do this:
Take the points in this case
(1,2) and (-2,2)
And you need to use the equation (x,y) --> (-x,y)
So the new points you NEED TO GRAPH ARE
(-1,2) and (2,2)
Hope this helped!
Answer: (-1,2) and (2,2)
Step-by-step explanation:
reflection over the y axis, take the point (x,y) and change the sign of the X-value (-x,y). When You reflect over the y-axis, the y remains the same.
point (1,2) would become (-1,2) reflected over the Y
and (-2,2) would become (2,2)

What is the value of y?
Answer:
95°
Step-by-step explanation:
120° = 25° + y ( exterior angle of a triangle is equal to the sum of two opposite interior angles)
y = 120° - 25°
y = 95°

Identify each pair of angles as corresponding, Alternate interior, alternate exterior, or consecutive interior and solve for X
Answer:
Step-by-step explanation:
19). Angles measuring 90° and (21x + 6)° are Alternate exterior angles.
Therefore, 21x + 6 = 90
2x = 90 - 6
2x = 84
x = 42
21). Angles measuring 60° and (8x - 4)° are Alternate interior angles,
8x - 4 = 60
8x = 60 + 4
x = [tex]\frac{64}{8}[/tex]
x = 8
23). Since, angles measuring (-1 + 14x)° and (12x + 17)° are Alternate exterior angles
Therefore, (-1 + 14x) = (12x + 17)
14x - 12x = 17 + 1
2x = 18
x = 9
25). Both the angles (x + 96)° and (x + 96)° are consecutive interior angles.
Therefore, (x + 96)° + (x + 96)° = 180° [Property of consecutive interior angles]
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -6
Now measure of (x + 96)° = -6 + 96
= 90°
26). Both the angles (20x + 5)° and (24x - 1)° are consecutive interior angles.
Therefore, (20x + 5)° + (24x - 1)° = 180°
44x + 4 = 180
44x = 176
x = 4
What is 39.79949748 rounded to the nearest hundredth?
Answer:
[tex]Number = 39.80[/tex]
Step-by-step explanation:
Given
[tex]Number = 39.79949748[/tex]
Required
Approximate (to the nearest 100th)
This means that, we approximate at the second digit after the decimal.
So:
i.e,
Number = 39.79 [Begin approximation] 949748
The first digit after [Begin approximation] is then approximated using the following rule:
[tex]0 - 4 \approx 0[/tex]
[tex]5 - 9 \approx 1\\[/tex]
Since 9 falls in [tex]5 - 9 \approx 1\\[/tex] category, the number becomes:
[tex]Number = 39.[79+1][/tex]
[tex]Number = 39.80[/tex]
Find the measure of an angle that is positive and less than 360° in standard position for each reference angle.
9514 1404 393
Answer:
112°285°202°Step-by-step explanation:
In quadrant II, the standard position angle is found by subtracting the reference angle from 180°.
180° -68° = 112°
__
In quadrant IV, the standard position angle is found by subtracting the reference angle from 360°.
360° -75° = 285°
__
In quadrant III, the standard position angle is found by adding 180° to the reference angle.
180° +22° = 202°
