A magazine collects these data measuring the battery life , in hours , of a sample of MP3 players : 5.7, 6, 6.1, 6.5, 6.8, 7.1, 7.4, 7.6, 8.1, 8.2 About how long does an MP3 player in the 50th percentile play ?
Answer:
the answer is 6.8
Step-by-step explanation:
The computation is shown below:
Since we have to determined the 50th percentile play
So,
= 50(nth value) ÷ number of observations
= 50(nth value) ÷ 10
= 5th value
= 6.8
Hence the answer is 6.8

Find the value of each variable using sine and cosine. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
copy and paste the above on to your computer for future reference
n= Hyp
m= adj
8 = Opp
∠=50°
sin(50) = 8/n
n = 8/sin(50)
n = 10.44325
n= 10.4 ( to nearest 10th)
tan(50) = 8 / m
m = 8 / tan(50)
m = 6.712797
m = 6.7 ( to nearest 10th )

The Pythagorean Identity states that:
(sin x)2 + (cos x)2 = 1
Given cos 0 = Ź, find sin 0.
sin 0 =
V 역
Simplify the fraction.

Answer:
√7 / 4
Step-by-step explanation:
Trigonometrical identity are used to show the relationship between the sides and angles of a right angled triangle. Some trigonometric identities are:
sinΘ = opposite / hypotenuse, cosΘ = adjacent / hypotenuse, tanΘ = opposite / adjacent.
Given that cosΘ = 3 / 4
Therefore, cosΘ = adjacent / hypotenuse = 3 / 4
adjacent = 3, hypotenuse = 4. Let x be the opposite side, to get the opposite side, we use Pythagoras theorem:
opposite² + adjacent² = hypotenuse²
x² + 3² = 4²
x² + 9 = 16
x² = 7
x = √7
sinΘ = opposite/hypotenuse = √7 / 4
What is the length of side c rounded to the nearest tenth of an inch?
17 in.
19 in.
С
The length of side c rounded to the nearest tenth of an inch is in.
Answer:
Step-by-step explanation:
This is a right triangle, and side c, our unknown, is the hypotenuse, the longest side in a right triangle. Using Pythagorean's Theorem, we have
[tex]17^2+19^2=c^2[/tex] which simplifies to
[tex]289+361=c^2[/tex] and

How do I do this please help
Answer:
C) 4,0
Step-by-step explanation:
Basically to find zeros you set up the expression equal to zero.
First pair is (0,0) they derived this by setting the leftmost x to 0 so x=0, this meant that when x was plugged back into the equation y = x(x-4) the y value we got out was 0 because y = 0 (0-4) = 0, thus the pair (0,0).
For second pair, we set up x-4= 0, solve this to get x = 4 (add 4 to both sides). Now plug this back into full equation y= 4 (4-4)= 0, you get y=0 and your ordered pair is (4,0) which is the second pair of zero.
Zero are x-intercept where y is zero which is the main reason why we setup x=0 or x-4=0 to start with.

Answer:
10 inches
Step-by-step explanation:
Surface Area = π R² + π R L [ L is Slant Height ]
200 π = π (10)² + π (10) L
200 π = π (100) + π (10) L
200 π - 100 π = 10 π L
100 π = 10 π L
100 π / 10 π = L
10 = L
L = 10 inches
Hope this Helps......

The bear moves closer, so Rick decides to go to the other side of the lake. Since there is a forest, he can only spotpoint A when angle C measures 50'. What trigonometric function would Rick
use to find AB if he knows the measure of BC ?
Answer:
Tangent
Step-by-step explanation:
Given
[tex]\angle C = 50[/tex]
See attachment for complete question
Required
Function to calculate BC
If AB is known, BC is calculated as:
[tex]\tan(C) = \frac{AB}{BC}[/tex]
Substitute d for AB and 50 for C
[tex]\tan(50) = \frac{d}{BC}[/tex]
Make BC the subject
[tex]BC = d * \tan(50)[/tex]
Hence, BC can be found using tangent

You bought a new water glass. The glass is cone-shaped and has a circular base. It has a
diameter of 3 inches and a height of 7.5 inches. What is the volume of the glass? Use 3.14 to
approximate pi. Round your answer to the nearest tenth.
Answer:
TO find the answer, first you have to find the formula for volume of a cone-
The formula is
V= 1/3 times base times height
So V= (1/3) (pi3^2) (12)
V= 113.04
By the way for the base you have to find the volume of a circle. I divided the diameter by 2 to find the radius.
and pi is 3.14
A card is drawn at random from an ordinary pack of playing cards. What is the probability that it is neither a face card nor a black card? 16/52 = 4/13 10/52 = 5/26 14/52 = 7/26 20/52 = 5/13
20 / 52 = 5 / 13
Step-by-step explanation:
Probability(P) is the likelihood of occurrence of an event. It is given by;
P = total number of favourable outcomes ÷ total number of possible outcomes
In a pack of playing cards, there are 52 cards altogether.
Therefore, the total number of possible outcomes = 52
To get the probability that a card drawn at random is neither a face nor a black card, the following should be noted.
i. There are 12 face cards in the pack. These are the kings (4 cards), queens(4 cards) and the jacks (4 cards).
Therefore, number of cards that are not face cards = 52 - 12 = 40
ii. Black cards are half of the total number of cards = 26.
These black cards contain half of the kings, queens and jacks cards = 6 which are already included in the face cards. Therefore, the remaining black cards will be 26 - 6 = 20
Neither a face card nor a black card = 40 - 20 = 20 [number of favourable outcomes]
The probability of getting neither a face card nor a black card is
=> total number of favourable outcomes ÷ total number of possible outcomes
=> 20 / 52 = 5 / 13

Find the principal that will yield a simple interest of Rs 9000 in 5 years at a rate of 6% per annum.
9514 1404 393
Answer:
₹ 30000
Step-by-step explanation:
The simple interest formula is ...
I = Prt . . . . . . principal P invested at rate r for t years
Fill in the values you know, and solve for the one you don't know.
9000 = P(0.06)(5)
9000/0.30 = P = 30000
The principal that will give ₹9000 in interest is ₹30000.
A =?
P= 9000
t = 5 yrs
r = 6% = 0.06
A = p(1+r)^t
A = 9000(1+0.06)⁵
A = 9000× 1.338
A = 12044 Rs.
Maha got a phone call while she was watching a movie. After she hung up, she rewound 15 minutes of the movie tape. Which point on the number line below represents −15? AlternativeText A. Z B. Y C. X D. W
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the number line is not given. The general explanation is as follows;
First, record the time she hung up (say, time = x)
To rewind 15 minutes back means, x - 15
So, point on the number line will be x - 15
Take for instance
[tex]x = 45[/tex]
The point on the number line will be:
[tex]x - 15 = 45 - 15[/tex]
[tex]x - 15 = 30[/tex]

A 25.5 foot ladder rests against the side of a house at a point 24.1 feet above the ground. The foot of the ladder is x feet from the house. Find the value of x to one decimal place.
Answer:
8.3
Step-by-step explanation:
Use the pythagorean theorem: a2 + b2 = c2 a2 would be 24.1 and c2 would be 25.5. square them then subtract a2 from b2. then find the square root of your answer which is 8.3
The line that goes through the points (0,-4) and (1,2) is......
Answer: The equation for the line is “y = 6x - 4”
Step-by-step explanation: To find this answer we will put it in slope-intercept form which is y = mx +b. To first find m which is the slope you subtract the the second y by the first y over the second x by the first x. It looks like this y2 - y1/ x2 - x1. After we find the slope which is 6, to find the y-intercept which is b we just plug a point we used to find the slope into the equation we have. It looks like this y = 6x + b —> 2 = 6(1) + b... I used (1,2). Then you solve for b by multiplying 1 by 6 and then subtracting 6 to both sides to get b by itself. So it goes from 2 = 6(1) + b into -4 = b. Then you just put -4 into b and you get the answer y = 6x - 4.

Answer:
[tex] \frac{x + 7 }{x - 3} [/tex]
Step-by-step explanation:
First factorize both expressions
[tex] \frac{ {x }^{2} + 11x + 28 }{x { }^{2} + x - 12} \\ \frac{x {}^{2 } + 7x + 4x + 28 }{x { }^{2} + 4x - 3x - 12 } \\ \frac{x(x + 7) + 4(x + 7)}{x(x + 4) - 3(x + 4) } \\ \frac{(x + 7)(x + 4)}{(x + 4)(x - 3)} [/tex]
Now you can cross out x+4
and you'll be left with

What is the supplement of ([dozen sixes] + 80)degrees?
28 degrees
22 degrees
82 degrees
188 degrees
Answer:
28°
Step-by-step explanation:
Supplementary angles sum to 180°
( dozen sixes) + 80
= 12 × 6 + 80
= 72 + 80
= 152°
supplement = 180° - 152° = 28°
Find the midpoint
(1,-8) (-7,0)
Answer:
(-3, -4)
Step-by-step explanation:
Handy fact: the average of two numbers is exactly halfway between them.
To find the midpoint, average the x-coordinates; average the y-coordinates.
(1 + -7)/2 = -6/2 = -3
(-8 + 0)/2 = -8/2 = -4
The midpoint is (-3, -4).
is "6x – (3x + 8) = 16x" a no solution
Answer:
no x = -8/13
Step-by-step explanation:
6x – (3x + 8) = 16x
Combine like terms
6x -3x -8 = 16
3x-8 = 16
Subtract 3x from each side
3x-8-3x = 16-3x
-8 = 13x
Divide by 13
-8/13 = 13x/13
-8/13 =x
Answer:
No, the answer would be -8/13
Step-by-step explanation:
6x-(3x+8)=16x
6x-3x-8=16x
3x-16x=8
-13x=8
x=-8/13
