A basket contains 6 pieces of paper numbered from 1 to 6. A hat contains the letters A, B, and C. If a blindfolded person picks a number and a letter, what is the probability that the number is even and the letter is A?

The two events are independent, so the probability of both happening is the product of the two.

Probability of picking an even number is 3/6=1/2
Probability of picking the letter A is 1/3 = 1/3

Product of probability of two independent events = (1/2)(1./3)=1/6.

QUESTION POSTED AT 21/01/2020 - 09:51 AM

Algebra 2 You and your friend Alex are looking to buy tickets for a big concert. You know that Ticket System charges $22 per person plus a $10 surcharge per transaction. You and Alex think you can get a better deal at Max Tickets, which charges $20 per ticket and surcharges $16 for each transaction. Or Ticket Meister, which charges $25 for a ticket and surcharges $4 per transaction, both of which are also selling tickets for the event. Pick one of these two sellers, and use your knowledge of linear systems to compare it with Ticket System and figure out who has the better deal.

To answer this problem, we convert the data given into linear equations. In this case,  for Max Tickets, the equation is 20 t +16; for Ticket Meister, the equation os 25 t + 4. The worth of two tickets and a transaction for Max Tickets is $20(2) + 16 = $56. For Ticket Meister, $25(2) + 4 = $54. Hence between the two, Ticket Meister should be chosen. Comparing to Ticket System which has $22(2) + 10 = $54, it is concluded that either Ticket Meister or Ticket system is practical to choose.

QUESTION POSTED AT 21/01/2020 - 09:48 AM

A school system is reducing the amount of dumpster loads of trash removed each week. in week 5, there were 40 dumpster loads of waste removed. in wee 10,there were 30 dumpster loads removed. Assume that the reduction in the amount of waste each week is linear. Write an equation in function form to show the amount of trash removed each week.

Since it is given that the reduction in the amount of waste each week is linear, it is conclusive that these data are also in arithmetic sequence. First, determine the common difference (d)
                                 d = (a10 - a5) / (10 - 5)
Subsituting the known values,
                                d = (30 - 40) / 5 = -2
To determine any term (at) of the arithmetic sequence,
                            at = a1 + (n - 1) x d 
Solve for a1 by using either the given a5 or a10,
                            40 = a1 + (5 -1) x -2     ; a1 = 48
The equation becomes, 
                                 at = 48 + -2(n -1)

QUESTION POSTED AT 21/01/2020 - 09:48 AM

Sonia rolls a six sided number cube 12 times and records of she rolls a 2. What is the number of trials for this binomial experiment?

Answer:

12

Step-by-step explanation:

Binomial expression: P(X=r) =^nC_r p^r q^{n-r}

Where n = No. of trials i.e. no. of times experiment occur

p= Probability of success

q= Probability of Failure

r= No. of success.

We are given that Sonia rolls a six sided number cube 12 times and records of she rolls a 2.

Since here the cube was rolled 12 times.

Thus n =12

So, No. of trials =12

Hence the number of trials for this binomial experiment is 12.

Given the function f(x) =5(x+4)-6 solve for the inverse function when x=19

F(x) = 5(x +4) - 6

let y = f(x)

y = 5x +20 - 6    solving for x.

y = 5x + 14

y - 14 = 5x

5x = y - 14

x = (y - 14)/5

Recall   f(x) = y.   Implies  x = f⁻¹(y)

x = (y - 14)/5

f⁻¹(y) = (y - 14)/5

So as well:

f⁻¹(x) = (x - 14)/5            when x = 19

f⁻¹(19) = (19 - 14)/5  = 5/5

Answer: D. (-14, -54)
 WORKINGS
 According to Table 1: y = 4x + 2 … (Equation I)
According to Table 2: y = 3x – 12 … (Equation II)
 Substitute the value of y in equation I (4x + 2) for y in Equation II to solve for x
y = 3x – 12
4x + 2 = 3x – 12
4x – 3x = -12 – 2
x = -14
 Substitute -14 for x in Equation I to solve for y
y = 4x + 2
y = 4(-14) + 2
y = -56 + 2
y = -54
 Therefore, x= -14; y = -54

What is the value of x in the equation 3x-1/9y=18, when y=27?

Hi Vanessa


3x -1/9 (27) =18

3x - 27/9 =18

3x- 3 =18

Add 3 to both sides

3x-3+3=18+3

3x=21

Divide both sides by 3

3x/3= 21/3

x= 7

The value of x is 7


Now let's check if my answer is correct

To check it we gonna replace x by 7 and 27 for y

(3)(7) -1/9 (27) = 18

21 -1/9 (27)=18

21- 27/9 = 18

21- 3 = 18

18 = 18

A furniture company currently produces 5900 chairs per month. If production increases 5%, find the increase and the new number of chairs

First, we need to find out 5% of 5900. So, multiply 5900 by 0.05 (this is 5% in decimal form, and to achieve this I divided 5 by 100), which equals to 295. This is the 5% increase. To achieve the new number of chairs, we add the increase amount to the original amount, so we add 5900 to 295, which equals 6195.

Which statement describes the graph of f(x) = 4x2 + 20x + 25? A.The graph does not intersect the x-axis B.The graph touches the x-axis at (–2.5, 0). C.The graph intersects the x-axis at (–0.4, 0) and (0.4, 0). D.The graph intersects the x-axis at (2, 0) and (5, 0).

To determine the nature of the graph and on what points will it intersect the x - axis, determine the roots of the graph first. One way to find the roots is to use the quadratic formula, x = (-b +/- sqrt(b^2 - 4ac))/ 2a. Using this formula we get, x = -2.5. Thus, the answer is letter B.

Answer:

As given Point A is the center of the circle.

We will answer this question by considering all the options.

Option 1. FA : AE    [ Both FA and EA are radius of circle .So their ratio can't be equal to 1:2.]

Option 2. CB : FE  [ CB is a chord and FE is a Diameter  as length of Chord not given, So we can't Predict about their Ratio.]

Option 3: FE : AH  [As FE is the Diameter and AH is radius.Diameter = 2 × Radius,So FE : AH=2:1]

Option 4 : AH : FE  [Explained above AH: FE=1:2]

Option 5:  AH : AD  [AH is the radius of the circle and D is any point on AH So their ratio can't be 1:2.]

Option (d) AH : FE = Radius : Diameter=1:2 is true.

Totally false.  Just take your picture and either rotate the radius just a little,
or rotate the chord just a little.  The radius will still intersect the chord, but
it won't bisect it.

Could it be possible that you might possibly have mis-copied the question.

If you said that the radius intersects the chord and is perpendicular to it,
then the statement would be true.  Could that be the reason that the little
'corner' is marked in on the drawing ... to show that they're perpendicular ?
