1. Find the median, mode, and mean for, {1, 4, 8, 3, 4, 5, 2, 2, 2, 5}
Answer:
Mean: 3.6
Median: 3.5
Mode: 2
Step-by-step explanation:
Mean: The sum of all numbers divided by the amount of numbers.
Median: The number in the middle.
Mode: the number that is frequently used.
------------------------------------------------------------------------------------------------------
Mean: 1 + 4 + 8 + 3 + 4 + 5 + 2 + 2 + 2 + 5 = 36 ÷ 10 = 3.6
Median: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. since two numbers are in the middle, we need to add 3 + 4 ÷ 2 = 3.5
Mode: 1, 4, 8, 3, 4, 5, 2, 2, 2, 5. The mode is two because it is used the most.
A jar contains 3 yellow and 7 green marbles. You randomly draw one marble from the jar then REPLACE it and randomly draw a second marble. Find the probability that you draw a yellow marble first and then a green marble.
3 yellow + 7 green = 10 total marbles.
The probability of picking a certain color is the number of that color over the total quantity.
Picking yellow would be 3 yellow / 10 total = 3/10
Picking green would be 7 green / 10 total = 7/10
To find the probability of doing both multiply the probability of each one by each other:
3/10 x 7/10 = 21/100
The answer would be 21/100

5) Find the value of x
Answer:
x = 28
Step-by-step explanation:
the angle shown is a right angle
right angle = 90°
•°• (x + 6) + 56 = 90
=> x + 62 = 90
=> x = 90 - 62
=> x = 28Answer:
28
Step-by-step explanation:
5)
(x + 6)° + 56° = 90°
x + 6 + 56 = 90
x + 62 = 90
x = 90 - 62
x = 28

Write the equation of a line passing through (-4.3) and perpendicular to -6x + 4y =-12.
Answer:
y=-2/3*x+1/3
Step-by-step explanation:
-6x+4y=-12
put into y=mx+b line equation
4y=6x-12
y=(6/4)x-(12/4)
y=(3/2)x-4
slope is 3/2
to find perpendiular line slope take the negative inverse.
-(2/3) = slope of perpendicular line
use line equation and solve for y-intercept (b)
3=(-2/3)*(-4)+b
3=8/3+b
b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.

2x(3x-5) -3(x-3)2(2)(3(2)-5) -3(2-3) First you substitute 2 for all the x's. The twos in . parentheses represent multiplication.4(6-5) -3(2-3) Second, you multiply 2 by 2, which equals 4, . and multiply 3 by 2, which equals 6. 4(1) -3(-1) Next, you solve the problems in the . parentheses, which is 6 minus 5 is 1, and 2 . minus 3 is -14-(-3) Next, you multiply 4 by 1, which is 4, and . multiply 3 by -1.4+3 Since two negatives make a positive, the . equation changes to 4 plus 3.7 Finally, you add 4 plus 3 and get 7.P.S: Sorry about the random periods. I had to put them in to format it like that.
What will be the multipicative inverse of 6?
Answer:
1/6
Step-by-step explanation:
The multiplicative inverse of a number is that number as the denominator, and 1 as the numerator. Let's solve this problem using that knowledge.
6 × ? = 1
6 × m = 1
(m stands for multiplicative inverse)
m = 1/6

Step-by-step explanation:

c (hypotenuse) = [tex]\sqrt{a^{2} +b^{2} }[/tex]
plug in values for a and b
c=[tex]\sqrt{6^{2} +8^{2} }[/tex]
c=[tex]\sqrt{36+64\\}[/tex]
c=[tex]\sqrt{100\\}[/tex]
c=10
Answer:
length of the hypotenuse = √100 = 10 ft
Step-by-step explanation:
This is a right triangle with leg lengths 6 and 8 ft. We apply the Pythagorean Theorem a^2 + b^2 = c^2, as follows:
(6 ft)^2 + (8 ft)^2 = c^2
Then c^2 = 100, and c = length of the hypotenuse = √100 = 10 ft

find the surface area of each figure. round to the hundredths place
Given:
In the given cone,
Radius of the cone = 7.2 m
Slant height of the cone = 17 m
To find:
The surface area of the cone.
Solution:
The surface area of a cone is:
[tex]A=\pi rl+\pi r^2[/tex]
Where, r is the radius of the cone and l is the slant height of the cone.
Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get
[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]
[tex]A=384.336+162.7776[/tex]
[tex]A=547.1136[/tex]
[tex]A\approx 547.11[/tex]
Therefore, the surface area of the given cone is 547.11 square m.

The terminal side of 0 is in quadrant IV and sin 0= -5/13 What is cos 0?
Answer:
cosθ = [tex]\frac{12}{13}[/tex]
Step-by-step explanation:
Given
sinθ = - [tex]\frac{5}{13}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
This is a 5- 12- 13 right triangle
with opposite = 5, adjacent = 12 , hypotenuse = 13
since θ is in 4th quadrant then cosθ > 0
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex]
The trigonometric ratio of cos θ in quadrant IV is 12/13.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
Sin θ = -5/13, and
θ lies in the quadrant IV.
By trigonometric ratio,
[tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]
⇒ [tex]sin \theta = -\frac{5}{13}[/tex]
Here opposite side = 5 and
hypotenuse side = 13
The adjacent side can be calculated by using the Pythagoras theorem,
[tex]Hypotenuse^{2} = opposite^{2} +adjacent^{2}[/tex]
⇒ [tex]adjacent = \sqrt{hypotenuse^{2} -opposite^{2} }[/tex]
⇒ [tex]adjacent = \sqrt{13^{2} -5^{2} }[/tex]
⇒ [tex]adjacent = \sqrt{169 -25 }[/tex]
⇒ [tex]adjacent = \sqrt{144}[/tex]
⇒ [tex]adjacent = 12[/tex]
Thus [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex]
⇒ [tex]cos \theta = \frac{12}{13}[/tex]
θ lies in the quadrant IV, so cos θ > 0.
Hence we can conclude that the trigonometric ratio of cos θ in quadrant IV is 12/13.
