Tara has a bag with 3 white marbles, 2 black marbles, and 5 green marbles. She will draw two marbles from the bag one at a time without replacement. What is the probability that she will draw a black marble and then a green marble?

Answers

Answer 1

Answer: 1/nine.

Step-by-step explanation:To locate the probability of drawing a black marble after which a inexperienced marble, we need to keep in mind the range of approaches we can draw a black marble and then a inexperienced marble, and divide that with the aid of the whole range of methods we are able to draw  marbles with out replacement.

The opportunity of drawing a black marble on the primary draw is two/10, because there are 2 black marbles out of a total of 10 marbles. Then, in view that we draw the second one marble with out alternative, there will be nine marbles left within the bag. If we drew a black marble on the first draw, there could be 1 black marble and five inexperienced marbles left in the bag. So the possibility of drawing a green marble on the second draw, for the reason that a black marble became drawn on the first draw, is five/nine.

The chance of drawing a black marble after which a inexperienced marble is the manufactured from the chance of drawing a black marble on the primary draw and the opportunity of drawing a inexperienced marble on the second draw, given that a black marble turned into drawn on the primary draw. So we multiply 2/10 by five/nine to get 1/nine.

Therefore, the chance of drawing a black marble after which a inexperienced marble is 1/nine.

Find the critical points of f(x,y) = 2x4 + 3y2 - 10xy-3

Answers

To find the critical points of a function, we need to determine the points at which the gradient of the function is zero or undefined.

In the case of the given function f(x,y) = 2x^4 + 3y^2 - 10xy - 3, we need to find the values of x and y where the partial derivatives of f with respect to x and y are both zero.

After taking the partial derivatives of the function with respect to x and y, we got two equations.

We solved these equations simultaneously to obtain the values of x and y at which the partial derivatives of f are both zero. The obtained values of x and y are the critical points of the function.

In this case, we got two critical points ( √(25/12), (25/12)√(3/5)), (- √(25/12), -(25/12)√(3/5)).

To check whether these critical points are maximum, minimum, or saddle points, we can use the second derivative test.

We can evaluate the second partial derivatives of f and plug in the values of x and y for each critical point to determine the nature of the critical points.

Answers

The t-value needed to develop the 95% confidence interval for the population mean SAT score is: t = 2.009

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data. It involves the use of methods and techniques to gather, summarize, and draw conclusions from data.

To find the t-value needed to develop the 95% confidence interval for the population mean SAT score, we can use the following formula:

t = (x - μ) / (s / √(n))

where:

x = sample mean (1300)

μ = population mean (unknown)

s = sample standard deviation (200)

n = sample size (49)

To find the t-value, we need to find the margin of error (ME) first:

ME = t* (s / √(n))

We know that for a 95% confidence interval, the critical value of t is 2.009 (from t-distribution table or calculator) with 48 degrees of freedom

(df = n-1).

suppose iq scores are normally distributed with μ = 100 and σ = 15. what percent of iq scores are between 85 and 130?

Answers

If IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, we can use the normal distribution properties to find the percentage of IQ scores between 85 and 130.

Specifically, we can standardize the scores and use a normal distribution table or calculator to find the area under the curve between the z-scores corresponding to 85 and 130.To find the percentage of IQ scores between 85 and 130, we first need to standardize the scores by subtracting the mean and dividing by the standard deviation. This gives:

z1 = (85 - 100) / 15 = -1.00

z2 = (130 - 100) / 15 = 2.00

We can then use a normal distribution table or calculator to find the area under the curve between these two z-scores. For example, using a standard normal distribution table, we can find that the area to the left of z = -1.00 is 0.1587 and the area to the left of z = 2.00 is 0.9772. Therefore, the area between these two z-scores is:

0.9772 - 0.1587 = 0.8185

This means that approximately 81.85% of IQ scores are between 85 and 130. Alternatively, we can use a normal distribution calculator to find the same result. For example, using an online calculator, we can input the mean (100), standard deviation (15), and the lower and upper limits (85 and 130) and obtain a probability of 0.8185, or 81.85%.

a triangular parcel of land has sides of lengths 860 feet, 820 feet and 1038 feet. a) what is the area of the parcel of land?

Answers

The area of the triangular parcel of land is approximately 305,682.4 square feet.

We can use Heron's formula to find the area of a triangular parcel of land. This formula states that the area of a triangle with sides a, b, and c is given by:
Area = √(s(s-a)(s-b)(s-c))
where s is the semi-perimeter of the triangle, given by:
s = (a + b + c)/2
Using the lengths of the sides given in the problem, we can calculate the semi-perimeter:
s = (860 + 820 + 1038)/2 = 1759
Then we can plug this value into Heron's formula to find the area:
Area = √(1759(1759-860)(1759-820)(1759-1038))
Area = √(1759×899×939×721)
Area = √(93587715844)
Area = 305682.4 square feet (rounded to the nearest tenth)

sin(55°) + sin(5°) = sin(65°) using a sum-to-product formula for sine

We can use the sum-to-product formula for sine to show that sin(55°) + sin(5°) = sin(65°). The formula is:

sin A + sin B = 2 sin[(A + B)/2] cos[(A - B)/2]

Substituting A = 55° and B = 5°, we get:

sin(55°) + sin(5°) = 2 sin[(55° + 5°)/2] cos[(55° - 5°)/2]

Simplifying, we get:

sin(55°) + sin(5°) = 2 sin(30°) cos(25°)

We know that sin(30°) = 1/2 and cos(25°) = sin(90° - 25°), so we can substitute these into the expression:

sin(55°) + sin(5°) =  sin(90° - 25°)

We also know that sin(90° - 25°) = sin(65°), so we can substitute this into the expression:

find the area of the surface obtained by rotating the curve x=6e2y x=6e2y from y=0y=0 to y=6y=6 about the yy-axis.

Answers

The area of the surface obtained by rotating the curve x = 6e^(2y) from y = 0 to y = 6 about the y-axis is approximately 1337.47 square units.

We can use the formula for surface area obtained by rotating a curve about the y-axis:

SA = 2π∫a^b f(x)√(1+(dy/dx)^2) dx

In this case, the curve is x = 6e^(2y) and we want to rotate it from y = 0 to y = 6. So, we have:

f(x) = 6e^(2y)

dy/dx = (1/2)(1/x) = (1/2e^(2y))

(1 + (dy/dx)^2) = 1 + (1/4e^(4y))

Substituting these values into the formula, we get:

SA = 2π∫0^6 6e^(2y)√(1+(1/4e^(4y))) dy

This integral is difficult to solve analytically, so we can use numerical methods to approximate the value. Using a numerical integration method, we get:

SA ≈ 1337.47

Find the flux of the fields F = 2xi - 3yj and across the circle F(t) = (a cost)i + (a sint)j; 0

Answers

flux of the fields F = 2xi - 3yj and across the circle F(t) = (a cost)i + (a sint)j is 0

The outward-pointing normal vector for a circle in the xy-plane is

n = -sin(t)i + cos(t)j

F = 2xi - 3yj

F(t) · n = (2x)(-sin(t)) + (-3y)(cos(t))

For a circle of radius a, we have

x = a cos(t) y = a sin(t)

F(t) · n = (2a cos(t))(-sin(t)) + (-3a sin(t))(cos(t))

F(t) · n = (2a cos(t))(-sin(t)) + (-3a sin(t))(cos(t))

F(t) · n =  -2a cos(t) sin(t) - 3a sin(t) cos(t)

F(t) · n =  -5a cos(t) sin(t)

Now, we can integrate this expression over the range 0 ≤ t ≤ 2π to

∫[0,2π] -5a cos(t) sin(t) dt

sin(A)cos(B) = 1/2[ sin(A + B) + sin(A - B) ],

we can rewrite the integrand

-5a cos(t) sin(t) = -2.5a [sin(2t)]

Now, we can integrate

∫[0,2π] -2.5a [sin(2t)] dt

Integrating sin(2t), we get

-2.5a [-cos(2t)/2] evaluated from 0 to 2π

Putting in the limits of integration, we have

= -2.5a [-cos(4π)/2 + cos(0)/2]

= -2.5a [-1/2 + 1/2]

On a recent statewide math test, the raw score average was 56 points with a standard deviation of 18. If the scores were normally distributed and 24,000 students took the test, answer the following questions. (d) How many of the 24,000 students receive a scaled score greater than a 90%?

Answers

To find the number of students who scored higher than a 90%, we first need to convert the 90% score to a z-score using the formula z = (x - μ) / σ, where x is the score we want to convert, μ is the mean, and σ is the standard deviation.

z = (90 - 56) / 18 = 1.89

Using a standard normal distribution table or calculator, we can find that the percentage of students who scored higher than a z-score of 1.89 is 3.22%.

So, the number of students who scored higher than a 90% would be:

0.0322 x 24,000 = 773.28

Rounding to the nearest whole number, we can say that approximately 773 students received a scaled score greater than a 90%.

There are a total of 78 students in a drama club and a yearbook club. The drama club has 12 more students than the yearbook club. How many students are in the drama club? the yearbook club?

Answers

Answer: 45

Step-by-step explanation:

Let's call the number of students in the yearbook club "x". Since the drama club has 12 more students, the number of students in the drama club would be "x+12".

We know that the total number of students in both clubs is 78, so we can set up an equation:

x + (x+12) = 78

Simplifying the equation:

2x + 12 = 78

Subtracting 12 from both sides:

2x = 66

Dividing both sides by 2:

x = 33

So there are 33 students in the yearbook club.

To find the number of students in the drama club, we can substitute x = 33 into the equation we set up earlier:

x + 12 = 33 + 12 = 45

Therefore, there are 45 students in the drama club.

Answer:

4. if you draw three cards from a deck of 52 cards one at a time without replacement, what is the probability that all three cards are diamonds?

Answers

The probability of drawing three cards from a deck of 52 cards one at a time without replacement and having all three cards be diamonds is 0.0026, or approximately 0.26%.

To calculate this probability, we can use the formula for conditional probability. The probability of drawing the first diamond is 13/52, since there are 13 diamonds in the deck. Once the first diamond has been drawn, there are 12 diamonds left out of 51 cards. So the probability of drawing a second diamond, given that the first card was a diamond, is 12/51. Finally, once two diamonds have been drawn, there are 11 diamonds left out of 50 cards. So the probability of drawing a third diamond, given that the first two cards were diamonds, is 11/50. Multiplying these three probabilities together gives us the probability of drawing three diamonds in a row, which is approximately 0.0026.

Answers

Answer:

We know that P(AB) = P(A) + P(B) - P(A∪B), where P(A∪B) represents the probability that at least one of the events A or B will occur.

To calculate P(A∪B), we can use the formula P(A∪B) = P(A) + P(B) - P(AB), which follows from the addition rule of probability.

Substituting with the given values, we have:

P(A∪B) = P(A) + P(B) - P(AB)

P(A∪B) = 3/4 + 1/2 - 7/8

P(A∪B) = 6/8 + 4/8 - 7/8

P(A∪B) = 3/8

Now, we can calculate P(AB) using the first formula:

P(AB) = P(A) + P(B) - P(A∪B)

P(AB) = 3/4 + 1/2 - 3/8

P(AB) = 6/8 + 4/8 - 3/8

Answers

The dairy farmer needs to sample at least 139 cities to estimate the true mean April 2023 retail whole milk price within $0.10 with 95% confidence.

To estimate the true mean April 2023 retail whole milk price with a margin of error of $0.10 and 95% confidence, a dairy farmer can use the sample size formula for estimating population means. The formula is:
n = (Z² × σ²) / E²
where n is the sample size, Z is the z-score corresponding to the desired confidence level, σ is the standard deviation of the population, and E is the margin of error.
For a 95% confidence level, the z-score (Z) is 1.96. The standard deviation (σ) of milk prices is $0.60, and the margin of error (E) is $0.10. Plugging these values into the formula, we get:
n = (1.96² × 0.60²) / 0.10²
n = (3.8416 × 0.36) / 0.01

Georg predicted that he would find 24 bags
of chocolate chips at the grocery store.
However, he only found 23 bags. What was
Georg's percent error?
Round to the nearest percent.

Answers

Georg's percent error is 4.30%.

The predicted value is 24 bags, and the actual value is 23 bags.

To find the percent error, we need to find the absolute value of the difference between the predicted value and the actual value, divide that by the predicted value, and multiply by 100 to get a percentage.

percent error = |(predicted value - actual value) / actual value| x 100%

Substituting the given values, we get:

percent error = |(24 - 23) / 23| x 100%

percent error = |1 / 23| x 100%

percent error = 4.3478%

Therefore, Georg's percent error is 4.30%.

Find the quadratic equation.

Answers

The quadratic equation of the graph is:

x² - 4x = 0

How to find the quadratic equation from the graph?

The quadratic equation of a quadratic graph can be found by check the points where the curve cuts or intersect the x-axis. These two x values can then be used to form the quadratic equation.

Looking at the graph, you will notice that the graph cuts the x-axis at points x = 0 and x = 4 (Check the red circles in the attached image). We will then form the equation the x values as follow:

x = 0 and x = 4

x - 0 = 0 and x - 4 = 0

Combining them and simplifying:

(x - 0)(x - 4) = 0

x(x - 4) = 0

x² - 4x = 0

Answers

The value of tan(A) is equal to 3/4.

Option B is the correct answer.

We have,

To find the tangent of angle A, we can use the formula for tangent in a right triangle, which is given by:

tan(A) = opposite/adjacent

In this case,

Side a is the length of the side opposite to angle A, and side b is the length of the side adjacent to angle A.

Given that b = 12 and a = 9, we can substitute these values into the formula:

tan(A) = a/b = 9/12 = 3/4

Therefore,

The value of tan(A) is equal to 3/4.

what is the standard form equation of the ellipse that has vertices (−6,−13) and (−6,7) and foci (−6,−4) and (−6,−2)?

Answers

The standard form equation of the ellipse is 24(x + 6)^2 + 5(y + 3)^2 = 600

Since the center of the ellipse is at the point (-6, -3), we can write the standard form equation of the ellipse as:

((x + 6)/a)^2 + ((y + 3)/b)^2 = 1

where "a" and "b" are the lengths of the semi-major and semi-minor axes, respectively.

The distance between the center (-6, -3) and the vertices (-6, -13) or (-6, 7) is 10, which is equal to 2a. So, a = 5.

The distance between the foci (-6, -4) and (-6, -2) is 2, which is equal to 2c (where c is the distance between the center and the foci). So, c = 1.

Using the relationship between a, b, and c in an ellipse (a^2 = b^2 + c^2), we can solve for b:

5^2 = b^2 + 1^2

25 - 1 = b^2

b = sqrt(24)

Therefore, the standard form equation of the ellipse is:

((x + 6)/5)^2 + ((y + 3)/sqrt(24))^2 = 1

Simplifying, we get:

24(x + 6)^2 + 5(y + 3)^2 = 600
