Find the inequality represented by the graph - khan academy
PLEASE HELP
Answer:
y ≤ x - 1
Step-by-step explanation:
The slope is 1 (every unit for x, there is a unit for y, rise/run is 1/1). The y-intercept is -1, because the line crosses the y-axis at -1. The graph is shaded below the line, and the line is solid, meaning that y is less than or equal to x -1, or y ≤ x - 1.
how important is writing the polynomial in standard form when dividing polynomial

While organizing her DVD collection, Jessica put 5 DVDs on the first rack, 10 DVDs on the second rack, 20 DVDs on the third rack, 40 DVDs on the fourth rack, and 80 DVDs on the fifth rack. If this pattern continues, how many DVDs will Jessica put on the sixth rack?
Answer:
160
Step-by-step explanation:
Number of DVDs put on the first rack = 5
Number of DVDs put on the second rack = 10
If we closely observe, the number of DVDs on the second rack is nothing but number of DVDs on the first rack multiplied by 2.
Number of DVDs put on the third rack = 20
If we closely observe, the number of DVDs on the third rack is nothing but number of DVDs on the second rack multiplied by 2.
Number of DVDs put on the fourth rack = 40
If we closely observe, the number of DVDs on the fourth rack is nothing but number of DVDs on the third rack multiplied by 2.
Number of DVDs put on the fifth rack = 80
If we closely observe, the number of DVDs on the fifth rack is nothing but number of DVDs on the fourth rack multiplied by 2.
Therefore, to find the number of DVDs on the sixth rack as per similar pattern, we need to multiply the number of DVDs on the fifth rack with 2.
Number of DVDs on the sixth rack = [tex]80\times 2 = \bold{160}[/tex]
Lucinda is saving money for a hot-air balloon trip to celebrate her graduation. She needs $300 dollars. Express this amount as an integer. Is this represented by a negative number or a positive number?
Answer:
Positive number
Step-by-step explanation:
Given that:
Lucinda is saving money for a hot-air balloon trip to celebrate her graduation and she needs $300 dollars.
Let x be the amount of her savings and she needs $300
SO;
x + 300 = 0
As an integer, it is represented by a positive number because she needs this amount of money in addition to what she already saved.

Answer:
2.1 gStep-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 0.70 × 3
We have the final answer as
2.1 gHope this helps you

Students in Mr. Lewis's class are reading a book that has 280 pages. Ramon decides to read 25% of the book each night. How many pages will Ramon read each night?
Answer:
Ramon will read 70 each night.
Step-by-step explanation:
25% of 280
REMEMBER: "Of" means to multiply
25% x 280
Convert the percent into a decimal
0.25 x 280 = 70
So Ramon will read 70 pages each night.
Hope this helps!!
how can you determine the additive inverse of a number. What is the sum of a number and its additive inverse?
Answer:
An example can be 14 + (-14) = 0
Whenever you encounter a problem like the one I put, your answer should ALWAYS be 0 because you start with 14. Now take away 14 you end up with 0.
Step-by-step explanation:

-4.5x > -21
Can someone help me ASAP
Step-by-step explanation:
-4.5 x > -21
4.5 = 9/2
WHEN DIVIDING INEQUALITIES WITH NEGATIVE SIGNS, THE GREATHER THAN SIGN WILL CHANGE TO LESS THAN.
-9/2x > - 21
Divide both sides by 9/2 or 4.5
-9/2x / - 9/2 > - 21 / - 9/2
x < 21 × 2/9
x < 7 × 2/3
x < 14/3
x < 4.66666667
Aproximately.... x < 4.7

Part B: You can also find the standard deviation for the binomial probability distribution of a specific outcome in a binomial experiment. Use the formula to find the standard deviation. You've already identified n and p in Part A. Show your work, and round your answer to two decimal places.
Answer:
Mean = np + n(n-1)p²
Standard Deviation= √ σ² = √npq
Step-by-step explanation:
The m.g.f of the binomial probability distribution b(x;n,p) is derived as below.
M₀t = E (e)^tx
= ∑(e)^tx (nCx) (p)^x q^(n-x) { x varies from 0 to n}
= ∑(e)^tx (nCx) (pe^t)^x q^(n-x)
= (q +pe^t)^n
The expansion of this binomial is purely algebraic and need not to be interpreted in terms of probabilities.
WE get the moments by differentiating M₀(t) once, twice, etc. with respect to t and putting t=0
Thus
μ₁` = E(X) = [ d/dt (q +pe^t)^n] t=0
= [ npe^t (q +pe^t)^n-1] t=0
= np
And
μ₂` = E(X²) = [ d²/dt² (q +pe^t)^n] t=0
= [ npe^t (q +pe^t)^n-1] + [ n(n-1)p²e^²t (q +pe^t)^n-2] t=0
= np + n(n-1)p²
Variance= μ₂= μ₂` - μ₁`²
σ² =E(X²)- E(X)²
σ² =np + n(n-1)p²- (np )²
σ² =npq
Standard Deviation= √ σ² = √npq

-2. 1w> 12.81
w<-6.1
Which graph matches the inequality?
Answer: The third one
Step-by-step explanation: open circle, with crocodile sign pointing to right which means u have to go left! Have a nice day!!
Answer:
C) a number line going from negative 6.5 to negative 5.8. An open circle is at negative 6.1. Everything to the left of the circle is shaded.
Step-by-step explanation:
Open circle means < or >
Closed circle means < or >
So has to be an open circle since the sign is <. it also says w < -6.1
so w has to be less than -6.1. So less than -6.1 would be -6.2, -6.3, -6.4etc.

1 Which ont represents the grach's 2007
A. Part C. Ponto
B Parts D. Point
Answer:
1. B. point B.
2. C. point C.
3. C. point C.
Step-by-step explanation:
1. In order to find the graph's y-intercept, we need to locate the point where the line crosses the y-axis. This will always happen at x=0, therefore, the y-intercept is located at point B (0,-4)
2. In order to find the x-intercept, we need to find the point where the line crosses the x-axis. This will generally happen when y=0, so that will be point C (2,0)
3. In order to find the graph's zero, we need to find the point where y=0. In other words, the graph's zero is the point where the function is equal to zero (the x-intercept) so this will br point C again (2,0)
Em um show foram 150 mil pessoas. Sendo 1/4 de pessoas estavam no camarote rosa, 1/5 no camarote lilas, 2/5 no camarote Amarelo, e 15% na pista. Qual foi o local que obteve maior número de pessoas? * 1 ponto a) Camarote Rosa b) Camarote Lilas c) Camarote Amarelo d) Pista
Responda:
camarote Amarelo
Explicação passo a passo:
Dado que:
Número total de pessoas = 150.000
Caixa rosa: 1/4 * 150.000 = 37.500
Caixa Lilax: 1/5 * 150.000 = 30.000
Caixa amarela: 2/5 * 150.000 = 60.000
Faixa = 0,15 * 150.000 = 22.500
Portanto, a caixa amarela tem mais gente

What is m<XYZ? I don't know how to solve
Answer:
<XYZ = 83
Step-by-step explanation:
we can see that the line XY is tangent to point Y
we can also the see that <XYZ intersects the line that forms arc 166
when a tangent line intersect the line that forms an arc, the angle formed by the tangent will be equal to half of the arc
so in other words angle XYZ is 0.5 of Arc 166
so <XYZ = 83
