In a lottery game, a player picks 6 numbers from 1 to 48. if 4 of those 6 numbers match those drawn, the player wins third prize. let's walk through the steps to determine the probability of winning third prize.In how many ways can 4 winning numbers be chosen from the possible 6 numbers?In how many ways can 2 non-winning numbers be chosen from the pool of all non-winning numbers? The number of favorable outcomes would be to multiply the above two answers together, since we want 4 winning numbers and 2 non-winning numbers. What is the number of favorable outcomes? In how many ways can you pick any 6 numbers from the pool of 50 numbers? This is your total outcomes. What is the probability of winning third prize?

3x+3n+20 is the answer

The function is decreasing on the interval (-∞, -2), has a local minimum at x = -2, is increasing on the interval (-2, 2), and is increasing on the interval (2, ∞). The function has a relative minimum at x = 3 (f(3) = -27) and no relative maximum.

Begin by finding the derivative of y.

y' = 3x^2 - 12

Find the critical numbers. (Enter your answers as a comma-separated list.)

To find the critical numbers, we need to solve y' = 0 for x:

3x^2 - 12 = 0

x^2 - 4 = 0

(x - 2)(x + 2) = 0

So the critical numbers are x = -2 and x = 2.

Test the intervals to determine the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation.)

To test the intervals, we can use a sign chart:

Interval (-∞, -2) (-2, 2) (2, ∞)

y' (-)(-) (-)(+) (+)(+)

y Decreasing Local Min Increasing

So the function is decreasing on the interval (-∞, -2), has a local minimum at x = -2, is increasing on the interval (-2, 2), and is increasing on the interval (2, ∞).

f(x) = x^4 - 4x^3

To find the relative extrema, we need to find the critical numbers and then evaluate the function at those points.

Find the derivative of f(x).

f'(x) = 4x^3 - 12x^2

Find the critical numbers by solving f'(x) = 0 for x.

4x^3 - 12x^2 = 0

4x^2(x - 3) = 0

x = 0 or x = 3

So the critical numbers are x = 0 and x = 3.

Evaluate the function at the critical numbers and the endpoints of the interval to find the relative extrema.

f(-∞) = ∞

f(0) = 0

f(3) = -27

f(∞) = ∞

So the function has a relative minimum at x = 3 (f(3) = -27) and no relative maximum.

When comparing exponential functions, the one with the bigger base expands more quickly. A logarithmic function grows more quickly if its argument is bigger.

Compared to polynomial functions, which in turn expand more quickly than logarithmic functions, exponential functions grow more quickly.

When comparing exponential functions, the one with the bigger base expands more quickly.

A logarithmic function grows more quickly if its argument is bigger.

We can arrange the provided functions in this manner by applying these rules:

log n, n, n log n, n, n2, n!, nn

Taking the function with the fastest rate of growth first: log n n n log n n 2

Each of these variables has a polynomial or logarithmic growth rate. The exponential functions will now be discussed:

2^n > n^2

Since polynomial functions increase more slowly than exponential functions, n2 grows more slowly than 2n.

The two categories with the fastest growth are: n! > n^2

n! grows more quickly than 2n and n2, as factorial functions expand even more quickly than exponential functions do. Finally:

n^n > n!

Therefore, nn grows more quickly than n! because exponential functions with bigger bases scale up more quickly than those with smaller bases.

Consequently, the following functions are listed in ascending order of growth rate:

Assume n is odd. Since n^3 is odd, n^3 + 5 should be even, but it's odd. Therefore, n is even.

The correct ranking of the options is:

As n^3 and 5 are odd, their sum n^3 + 5 should be even, but it is given to be odd. This is a contradiction.

Suppose that n^3 + 5 is odd and that n is odd. We know that the sum of two odd numbers is even. As n is odd, n^3 is odd. Therefore, our supposition was wrong; hence n is even.

The proof by contradiction shows that the assumption that n is odd leads to a contradiction with the given fact that n^3 + 5 is odd. Therefore, the assumption that n is odd must be false, and hence n is even.

The proof begins by assuming that n is odd and showing that this leads to a contradiction with the given fact that n^3 + 5 is odd. Specifically, since the sum of two odd numbers is even, n^3 + 5 should be even if n is odd. However, we know that n^3 + 5 is odd, so our assumption that n is odd must be false, meaning that n is even.

The mean and median of given data of population change for the ten most populous counties in the US from 2000 to 2010 is 7.2% and 6.25%.

To find the mean of the data, we need to add up all the percent changes and divide by the total number of counties:

Mean = (3.1 - 3.4 + 20.3 + 24.2 + 10.0 + 5.8 + 1.6 + 10.8 + 6.7 + 0.1) / 10 = 7.2%

Therefore, the mean percent change for the ten most populous counties in the US from 2000 to 2010 is 7.2%.

To find the median of the data, we first need to order the percent changes from smallest to largest:

-3.4, 0.1, 1.6, 3.1, 5.8, 6.7, 10.0, 10.8, 20.3, 24.2

Since there are an even number of values, the median is the average of the two middle values, which in this case are 5.8 and 6.7. Therefore, the median percent change for the ten most populous counties in the US from 2000 to 2010 is (5.8 + 6.7) / 2 = 6.25%.

The better description of the center of this data is the median, because it is less affected by outliers than the mean. In this case, the percent change for Maricopa County, AZ (24.2%) is much larger than the other values, and it pulls the mean upward. The median, on the other hand, is not affected by outliers, and it gives a better representation of the typical percent change for these counties.

To find out how much interest will be paid on a $155,000 house if a monthly payment of $850 is made for 30 years, we can use the formula for the total interest paid on a fixed-rate mortgage loan:

Total Interest = (Monthly Payment x Number of Payments) - Loan Amount

where Monthly Payment is $850, Number of Payments is 30 years x 12 months/year = 360 months, and Loan Amount is $155,000.

Plugging in these values, we get:

Total Interest = ($850 x 360) - $155,000

Total Interest = $306,000 - $155,000

Total Interest = $151,000

Therefore, the total interest paid on the $155,000 house over 30 years with a monthly payment of $850 is $151,000.

The measurements of the parking spaces shown do not meet the requirements of the town. The first parking space has an area of 144 square feet, while the second parking space has an area of 128 square feet. Both measurements are below the minimum area of 169 square feet required.

The area of the figure can be found by using the formula for the area of a regular polygon. Since the figure is composed of four 60-degree angles and four sides, the formula can be expressed as:

A = (1/2) * (a * s) * n

Where a is the length of one side of the polygon, s is the length of the apothem (a line perpendicular to the center of the polygon to a corner), and n is the number of sides of the polygon.

Since the figure has four sides of equal length (5 meters each), the length of the apothem can be calculated by using the Pythagorean theorem. The equation for the apothem is:

s = [tex](4^{2} - 5^{2} ) ^{0.5}[/tex]

Plugging these values into the area formula yields:

A = (1/2) * (5 * 4.472) * 4

A = (1/2) * (22.36) * 4

A = 44.72 square meters

The kinetic energy (in joule) of the asteroid is, 33 million

The kinetic energy is the energy associated with the particle having mass m and moving with the velocity v.

To find the kinetic energy of the asteroid, we need to use the formula:

KE = (1/2)mv²

where KE is the kinetic energy, m is the mass of the asteroid, and v is its velocity.

The mass of the asteroid can be calculated using its density and volume:

V = (4/3)πr³

where V is the volume of the asteroid, r is its radius, and π is the mathematical constant pi.

Since the asteroid is spherical, its radius is half its diameter, which is 0.54 km.

So,

V = (4/3)π(0.54 km)³

  = 0.65 km³

The mass of the asteroid is then:

m = density × volume

   = 3000 kg/m³ × 10⁹ m³/km³ × 0.65 km³

   = 1.95 × 10¹² kg

Now we can calculate the kinetic energy:

KE = (1/2)mv²  

     = (1/2) × 1.95 × 10¹² kg × (23.0 km/sec)²

     = 1.32 × 10²³ joule

To convert this to megatons of TNT, we divide by the energy of one megaton:

= 1.32 × 10³ joule / (4 × 10¹⁵ joule/megaton)

= 3.3 × 10⁷ megatons

Answer:

k = 23/7

Step-by-step explanation:

To solve the problem, we can use the fact that the product of the slopes of two perpendicular lines is -1. We can start by finding the slope of the line passing through the points (3, 5) and (k, 12).

slope = (12 - 5) / (k - 3)

We can simplify this expression by multiplying both numerator and denominator by -1:

slope = (-7) / (3 - k)

Now, let's find the slope of the line passing through the points (0, 7) and (2, 10):

slope = (10 - 7) / (2 - 0) = 3 / 2

Since the two lines are perpendicular, we can set the product of their slopes equal to -1:

(-7) / (3 - k) * (3 / 2) = -1

Simplifying this equation, we get:

(7/2) * (3 - k) = 1

Multiplying both sides by 2/7, we get:

3 - k = 2/7

Subtracting 3 from both sides, we get:

-k = 2/7 - 3 = -21/7 - 2/7 = -23/7

Finally, dividing by -1, we get:

k = 23/7

Therefore, the value of k that makes the statement true is k = 23/7.

Answer:

Step-by-step explanation:

m1=y2-y1/x2-x1=12-5/k-3=7/k-3

m2=10-7/2-0=3/2

two lines with slopes m1 and m2 are perpendicular if m1×m2 = -1.

(7/k-3) *3/2=-1

3(7)=-2(k-3)

21=-2k+6

-2k=15
