The percentage of students who attended the talent show for years 2018 to 2013 I shown year | percent of students 2008 | 83% 2009 | 85% 2010 | 89% 2011 | 84% 2012 | 88% 2013 | 81% This year the school has a total of 400 students. How many students do you expect to attend the talent show this year explain how you found your answer please!:)
Answer:
[tex]Students = 340[/tex]
Step-by-step explanation:
Given
[tex]2008 \to 83\%[/tex]
[tex]2009 \to 85\%[/tex]
[tex]2010 \to 89\%[/tex]
[tex]2011 \to 84\%[/tex]
[tex]2012 \to 88\%[/tex]
[tex]2013 \to 81\%[/tex]
[tex]n = 400[/tex]
Required
The expected number of students
First, calculate the average attendance in the 6 years of the talent show.
[tex]\bar x = \frac{83\% + 85\% + 89\% + 84\% + 88\% + 81\%}{6}[/tex]
[tex]\bar x = \frac{510\%}{6}[/tex]
[tex]\bar x = 85\%[/tex]
The expected number of students is:
[tex]Students =n * \bar x[/tex]
[tex]Students = 400 * 85\%[/tex]
[tex]Students = 340[/tex]
two teams play a series of games, wher both teams have an equal probability of winning each game. its a best- of-five series, so the frist team to win three games is the winner. what is the probability that the series lasts five games
Answer:
0.375
Step-by-step explanation:
With equal probability, hence
p for both teams = 0.5
First team to win three games win, probability that series lasts 5 games :
This means after 4 games each of the teams must have won 2 each ; and the series decider will be on the 5th game :
Each team winning two games and any of the teams could be the eventual winner :
From binomial relation :
P(x = x) = nCx * p^x * q^(n-x)
q = 1 - p = 0.5
Team A :
Winning any 2 from 4 and winning the 5th
(4C2 * 0.5^2 * 0.5^2) * 0.5
0.375 * 0.5 = 0.1875
Team B :
(4C2 * 0.5^2 * 0.5^2) * 0.5
0.375 * 0.5 = 0.1875
Hence, the probability that series lasts five games is :
[4C2*0.5^2*0.5^2)*0.5]+[4C2*0.5^2*0.5^2)*0.5]
0.1875 + 0.1875
= 0.375

Hi there! See the Identity below in the box:
[tex] \large \boxed{(f - g)(x) = f(x) - g(x)}[/tex]
We are also given that:
f(x) = 0g(x) = 7x+9Substitute both values in the equation.
[tex] \large{(f - g)(x) = 0 - (7x + 9)} \\ \large{(f - g)(x) = - (7x + 9)}[/tex]
Recall the property:
(-)(-) = +(+)(+) = +(-)(+) = -(+)(-) = -Same sign multiplying the same sign = + while opposite = -
Using the distribution property, distribute the negative sign in 7x+9. Since 7x+9 are positive for both terms - distributing in would turn the expression in negative form.
[tex] \large{(f - g)(x) = - 7x - 9}[/tex]
Hence, the answer is -7x-9.
Questions about the problem and my answer or explanation can be asked through comment.
Furthermore, (f-g)(x) is like a factored form of f(x)-g(x).
Hope this helps, and Happy Learning! :)
CAN SOMEONE HELP ME WITH THE ONE THAT SAYS 5 PLSS
Answer:
x = - 1, x = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given
3x² + 2x - 1 ( to find the zeros, equate to zero )
3x² + 2x - 1 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 1 = - 3 and sum = + 2
The factors are + 3 and - 1
Use these factors to split the x- term
3x² + 3x - x - 1 = 0 ( factor first/second and third/fourth terms )
3x(x + 1) - 1 (x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(3x - 1) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x - 1 = 0 ⇒ 3x = 1 ⇒ x = [tex]\frac{1}{3}[/tex]
Answer:
x= 1/3, -1
Step-by-step explanation:
So you can solve this via graphing or solving, I will show both. By solving first you factor the equation and set it equal to 0 (this is because for x intercept y=0)
0 = (3x-1) (x+1)
Use math to solve for x,
3x-1=0
3x=1
x=1/3
(not sure if your teacher wants 1/3 as decimal or fraction, if decimal then use 0.333 in place of 1/3)
x+1=0
x= -1
As far as graphing, just plug the equation in Desmos and wherever the graph cross the x axis is where y values are 0 (which are the x intercepts) and you get the same value.

Here's your question most important and definatily come in your exam...
Answer:
11 - 6√3
Step-by-step explanation:
Given the expression;
5+2√3/7+4√3
Rationalize
5+2√3/7+4√3 * 7-4√3/7-4√3
= 35 - 20√3+14√3 - 24/49 - 16(3)
= 35 - 20√3+14√3 - 24/49 - 48
= 35 - 20√3+14√3 - 24
= 35 - 6√3- 24
= 35 - 24 - 6√3
= 11 - 6√3
This gives the required solution

"A 20-foot ladder leans against the side of a house. The bottom of the ladder is 6 feet away from the house. What is the measure of the angle formed by the ladder and the ground?" How do I answer this?
Answer:
Value of θ [Angle of elevation] = 72.54°
Step-by-step explanation:
Given;
Length of foot ladder = 20 feet
Distance of foot from house (Base) = 6 feet
Find:
Angle of elevation
Computation:
Using trigonometry functions
Cos θ = Base / Hypotenuse
Cos θ = Distance of foot from house (Base) / Length of foot ladder
Cos θ = 6 / 20
Cos θ = 0.3
Cos θ = Cos 72.54
Value of θ [Angle of elevation] = 72.54°

The circle below is centered at the origin and has a radius of 10. What is its
equation?
Answer:
x^2 + y^2 = 100
Step-by-step explanation:
The general form of the equation of a circle is
(x-h)^2+(y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-0)^2+ (y-0)^2 = 10^2
x^2 + y^2 = 100

Unit 9 test: Trigonometry
What’s the correct answer to this problem
Answer:
See below.
Step-by-step explanation:
Remember SOHCAHTOA.
Soh...
Sine = Opposite / Hypotenuse
...cah...
Cosine = Adjacent / Hypotenuse
...toa
Tangent = Opposite / Adjacent
sin(64) = x / 94
Multiply both sides by 94.
94sin(64) = 94x / 94
Simplify
x = 94sin(64)
x = 84.487 = 84.5

Graph the equation. y=2x^2-8x+3y=2x 2 −8x+3
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.
y = 2(x^2 -4x) +3
y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square
y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form

Answer:
[tex] 208.5 \: {units}^{2} [/tex]
Step-by-step explanation:
Area of the figure = Area of rectangle with dimensions 13 by 10 units + Two times the area of one semicircle with radius (10/2 = 5) 5 units.
[tex] = lb + 2 \times \frac{1}{2} \pi {r}^{2} \\ = 13 \times 10 + 3.14 {(5)}^{2} \\ = 130 + 3.14 \times 25 \\ = 130 + 78.5 \\ = 208.5 \: {units}^{2} [/tex]

Rachel is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges $79 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.70 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer:
65 + .70(20)= 79 dollars
Step-by-step explanation:
65+0.70miles = Fee
this means she can drive 19 miles and she will still be below the price company A but as soon as she drives 20 miles company A and B will cost the same

Assume the
28 Water is being poured into a fish tank at a rate of 2 L every 10 seconds. The tank is 1.2 m long by Im
wide by 80 cm high. How long will it take to fill the tank? Give the answer in minutes.
Answer:
80 minutes
Step-by-step explanation:
1. Determine the volume of the tank
volume = length x width x height
100 cm = 1 meter
80cm /100 = 0.8m
1.2 x 1 x 0.8 = 0.96m³
2. convert litre to meter
1 liter = 0.001 m
2 litres = 0.002m
3. determine the time it would take to fill 0.96m
(0.96x 10) / 0.002 = 4800 seconds
4. convert seconds to minutes
60 seconds = 1 minute
4800 seconds / 60 = 80 minutes
2l = 0.0
