An opaque bag contains three red, two blue, and four green
marbles. What is the probability of randomly pulling out a red
marble, replacing it, then randomly drawing another red
marble?

Answers

Answer 1

Answer:

1/9

Step-by-step explanation:

Probability of drawing 1st red marble

No. (red) / No. (total)3 / (3 + 2 + 4)3/91/3 - P(1)

Probability of drawing 2nd red marble

It states it is replacedNumber of red is same as the beginning and total number is sameP(2) = P(1)1/3 - P(2)

Probability

P(1) x P(2)1/3 x 1/3P = 1/9

a. Which cost category varies the least among the different types of​ colleges? Can you explain why this category varies so​ little?
b. Ignoring the​ "other expenses"​ category, the general trend is for all categories to cost more as you look down the chart from​ two-year public colleges to​ four-year private colleges.​ However, one category is an exception to this trend. Which​ category? Can you explain​ why?

Answers

The question indicated above speaks to expense analysis for anonymous colleges. See the details of the analyses below.

From the pictorial representation, which cost category varies the least among the different types of​ colleges?

The cost category that varies the least amongst the various types of colleges is Books and supplies. Notice that at no point did it go below 1,097, nor above, 1,350.

The categories that do not cost more as one goes down the chart (apart from other expenses) are:

Books and supplies and Transportation.

Books and supplies went from: $1,350 to $1,107, to 1,107, and then to 1097. Hence decreasing gradually over time.

Transportation also decreased over time starting out from $2,152, to $2,099, to 2,099 and then flatting out at $1,571.

It may be explained that the cost of books is on the decline as more and more people prefer online reading while the cost of transportation is declining as more and more students use their cars or vehicles to the college, hence driving down the cost of transportation.

Fundamental theorem of calculus
[tex]g(s)=\int\limits^s_6 {(t-t^4)^6} \, dt[/tex]

Answers

Answer:

[tex]\displaystyle g'(s) = (s-s^4)^6[/tex]

Step-by-step explanation:

The Fundamental Theorem of Calculus states that:
[tex]\displaystyle \frac{d}{dx}\left[ \int_a^x f(t)\, dt \right] = f(x)[/tex]

Where a is some constant.

We can let:
[tex]\displaystyle g(t) = (t-t^4)^6[/tex]

By substitution:

[tex]\displaystyle g(s) = \int_6^s g(t)\, dt[/tex]

Taking the derivative of both sides results in:
[tex]\displaystyle g'(s) = \frac{d}{ds}\left[ \int_6^s g(t)\, dt\right][/tex]

Hence, by the Fundamental Theorem:

[tex]\displaystyle \begin{aligned} g'(s) & = g(s) \\ \\ & = (s-s^4)^6\end{aligned}[/tex]

If A is the center of the circle, then which statement explains how segment GH is related to segment FH?


Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles.

segment GH ≅ segment FH because arc EF ≅ arc GF
segment GH ≅ segment FH because the inscribed angles that create the segments are congruent.
segment GH ≅ segment FH because the tangents that create the segment FG share a common endpoint.
segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A.

Answers

Statement fourth the segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A if Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent, and angles EDA and GHA are right angles.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have AH as the radius and FG as a chord

AH is perpendicular to FG, AH⊥FG

As we know that a line passing through the center and perpendicular to the chord, bisects the chord.

∴ AH bisects FG

∴ FH = GH

Thus, the segment GH ≅ segment FH because segment FG is perpendicular to a radius of circle A if Circle A with inscribed triangle EFG; point D is on segment EF, point H is on segment GF, segments DA and HA are congruent and angles EDA and GHA are right angles.

Please help! Determine the function which corresponds to the given graph.

Answers

By identifying that it is a translation of the natural logarithm, we see that the function is:

g(x) = ln(x - 5).

How to determine the function?

We can see that the function has a logarithmic behavior. We know that the function:

f(x) = ln(x)

Has an asymptote at x = 0, and is equal to 0 for x = 1.

For our function, we can see that the asymptote is at x = 5 and the zero is at x = 6. So the graphed function seems to be the natural logarithm translated 5 units to the right.

Then the function graphed is:

g(x) = f(x - 5) = ln(x - 5)

If the bottom row as a result of synthetic division is 3, 0, 4, 0, 1. then the quotient is what?

Answers

Answer:

Step by step explanation:

Hope it helps you in your learning process.

Have a great day ahead.

The quotient and remainder for the last row of the synthetic division 3, 0, 4, 0, 1 are 3x³ + 4x, and 1 respectively.

The option representing this is, a. 3x³ + 4x R1.

What is synthetic division?

Synthetic division is a short method of dividing a polynomial p(x) by another polynomial (x - c), to get the quotient and remainder.

The last row represents the quotient and remainder, the last digit being the remainder, and the others being the quotient multiplied by leading powers of x, starting from x⁰, starting from the second last term of the last row.

How to solve the question?

In the question, we are given the last row of a synthetic division as 3, 0, 4, 0, 1, and we are asked to find the quotient of the division.

The last number, 1 represents the remainder and can be written as R1.

Now we move from the back to the front and multiply every number with the leading power of x, starting from x⁰.

0 gives 0 * x⁰ = 04 gives 4 * x¹ = 4x0 gives 0 * x² = 03 gives 3 * x³ = 3x³.

Therefore, the quotient and remainder for the last row of the synthetic division 3, 0, 4, 0, 1 are 3x³ + 4x, and 1 respectively.

The option representing this is, a. 3x³ + 4x R1.

Answers

Using conditional probability, it is found that there is a 0.521 = 52.1% probability that they have perfect attendance, given they made he honor roll.

What is Conditional Probability?

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which:

P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.

In this problem, the events are:

Event A: Student made the honor roll.Event B: Student has perfect attendance.

The probabilities are given by:

[tex]P(A) = 0.48, P(A \cap B) = 0.25[/tex]

Hence the conditional probability is given by:

[tex]P(B|A) = \frac{0.25}{0.48} = 0.521[/tex]

7. If (0.2)x = 2 and log 2 = 0.3010, then the value of x to the nearest tenth is?​

Answers

(0.2)x = 2.

Taking log on both sides

log (0.2)x = log 2.

x log (0.2) = 0.3010, [since log 2 = 0.3010].

x log (2/10) = 0.3010.

x [log 2 - log 10] = 0.3010.

x [log 2 - 1] = 0.3010,[since log 10=1].

x[-0.699] = 0.3010.

x= 0.3010/-0.699.

x= = -0.4306….

x= = -0.4.

(0.2)x = 2.

Taking log on both sides

log (0.2)x = log 2.

x log (0.2) = 0.3010, [since log 2 = 0.3010].

x log (2/10) = 0.3010.

x [log 2 - log 10] = 0.3010.

x [log 2 - 1] = 0.3010,[since log 10=1].

x[-0.699] = 0.3010.

x = 0.3010/-0.699

x = -0.4306

x= -0.4 (nearest tenth)

REASON:
1)Any angles opposite eachother is a cross with straight lines are equal. Therefore angle DOE is also 40. We know DOF is 120 so EOF must be 120-40=80 (which is DOF-DOE). BOC is opposite EOF so it also equals 80.

2) We know that angles on 1 straight line equal to 180 degrees. And we have to angles on a straight line but we are missing one which is COD. So we do (180-BOC-the angle we are given) 180-80-40= 60
