If Atharv has 10 nickels and dimes in his pocket, and they have a combined value of 70 cents, then he has 1 nickels and 4 dimes.

Let x be the number of nickels and y be the number of dimes. A nickel is worth 5 cents, and a dime is worth 10 cents. Therefore, we can write two equations:

x + y = 10 (since he has 10 coins in total)

5x + 10y = 70 (since the combined value of the coins is 70 cents)

We can simplify the second equation by dividing both sides by 5:

x + 2y = 14

Now we can use the first equation to solve for one of the variables in terms of the other. Let's solve for x:

x + y = 10x = 10 - y

Now we can substitute this expression for x into the second equation:

x + 2y = 14(10 - y) + 2y = 14

Simplifying, we get:

10 + y = 14

y = 4

Therefore, Atharv has 5 - 4 = 1 nickel and 5 - 1 = 4 dimes.

The conclusion of the test is the calculated z-test value of -1.5 falls within the acceptable limits of +/- 2 sigma.

To interpret the results of the run test, we need to compare the calculated z-test value with the acceptable limits for the test. The acceptable limits for the run test are +/- 2 sigma, which means that the process is considered acceptable if the z-test value falls within this range.

Since the z-value of -1.5 falls within the acceptable limits of +/- 2 sigma, we can conclude that the process is acceptable according to the run test. This means that there is no evidence of non-randomness or nonconformity in the process, and the process is functioning as expected.

The probability that the person is actually innocent given that they have failed the test is 0.4615... or approximately 0.462.

The question asks us to calculate the probability that the person is actually innocent given that they have failed the test. The probability that the person is actually innocent is given by the formula: P(innocent | fails test) = P(innocent and fails test) / P(fails test).

Now we need to calculate the values of the probabilities on the right-hand side of this equation. P(fails test) is equal to the sum of the probabilities that a guilty person fails the test and that an innocent person fails the test. Hence, P(fails test) = P(guilty and fails test) + P(innocent and fails test). P(guilty and fails test) = 0.2 × 0.7 = 0.14P(innocent and fails test) = 0.8 × 0.15 = 0.12. Therefore, P(fails test) = 0.14 + 0.12 = 0.26.

Finally, we can calculate the probability that the person is actually innocent given that they have failed the test: P(innocent | fails test) = P(innocent and fails test) / P(fails test)= 0.12 / 0.26= 0.4615 (rounded to four decimal places).

The length of altitude CD is 133/25 units.

What is the length if altitude?

To find the length of altitude CD, we need to find the length of the line segment CD, which is perpendicular to AB and passes through the point C.

First, let's find the equation of the line AB. We can use the two-point form:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is one of the points on the line. Using points A and B, we get:

m = (0 - 6)/(8 - 0) = -3/4

y - 6 = (-3/4)(x - 0)

y = (-3/4)x + 6

Next, let's find the slope of the line CD, which is the negative reciprocal of the slope of AB. This is because perpendicular lines have slopes that are negative reciprocals of each other. Therefore:

m_CD = 4/3

Now we can use the point-slope form to find the equation of line CD. We know that the line passes through point C (5, 8), so:

y - 8 = (4/3)(x - 5)

Simplifying, we get:

y = (4/3)x - 4/3 + 8

y = (4/3)x + 20/3

Now we need to find the intersection of line CD with line AB. We can solve the system of equations:

y = (-3/4)x + 6

y = (4/3)x + 20/3

Setting the two expressions for y equal to each other, we get:

(-3/4)x + 6 = (4/3)x + 20/3

Multiplying both sides by 12, we get:

-9x + 72 = 16x + 80

25x = -8

x = -8/25

Substituting this value of x into either equation, we get:

y = (-3/4)(-8/25) + 6 = 57/25

Therefore, the point of intersection is (-8/25, 57/25).

Finally, we can use the distance formula to find the length of CD, which is the distance between C and the point of intersection:

d = √[(5 - (-8/25))² + (8 - 57/25)²]

d = √[(125/25 + 8/25)² + (200/25 - 57/25)²]

d = √[(133/25)² + (143/25)²]

d = √(17689/625)

d = 133/25

Therefore, the length of altitude CD is 133/25 units.

The given statement "the sampling distribution becomes approximately normal, for all statistics, if there is a large enough sample size" is True as it is proved by the central limit theorem.

The central limit theorem (CLT) states that for large enough sample sizes, the distribution of the sample means approximates a normal distribution regardless of the shape of the initial population distribution.

It is a statistical theory that clarifies how the mean of a random sample of independent observations drawn from a non-normal population converges in distribution to a normal population.

According to this theory, the sample size should be at least 30 for the sample mean to have an approximately normal distribution. The following are the fundamental assumptions of the central limit theorem:

In the bridge, when the south has 13 points and 3 clubs and bids 1 club, the north responding with 3 clubs means that the North has a strong hand with six or more clubs.

In the game of bridge, bidding is a method of indicating the strength of a player's hand, which is the number of tricks that they believe they can win if they become the declarer. Every player has to declare their abilities based on the bid of the previous player when it is their turn to bid.

The bidding starts with the dealer and proceeds in a clockwise direction. The players can either make a bid or pass. The following are the four basic bids in Bridge:

When South has 13 points and 3 clubs, he makes a 1 Club bid. This bid can be interpreted as follows:

South has a strong hand with five or more clubs and 13 to 21 high card points. When South bids 1 Club, he implies that he has a balanced hand, which means that he has four cards in each suit, or an unbalanced hand, which means that he has a long suit, a singleton, or a void in some other suit.

When North responds with 3 Clubs, it means that he has a strong hand with six or more clubs. North has understood that South has five or more clubs and therefore responds with the number of clubs that he has in his hand to show that he is strong enough to support South's suit. Thus, North is trying to force South to become the declarer in clubs.

The present value that must be invested to get $2500 after 6 years at a simple interest rate of 11.0% is $1509.64.

In this case, we know the final amount that we want to have after 6 years, which is $2500. We also know the interest rate, which is 11.0%. What we need to find is the principal amount, which is the present value that we must invest now to achieve the desired future value.

Using the formula for simple interest, we can rearrange it to solve for the principal:

Principal = Simple Interest / (Rate x Time)

We know that the simple interest is the difference between the final amount and the principal amount. Therefore, we can substitute the values into the formula:

$2500 - Principal = (Principal x 0.11 x 6)

Simplifying the equation, we get:

$2500 = Principal + (0.66 x Principal)

$2500 = 1.66 x Principal

The heights of the tips of the propeller blades at π/6, 5π/6, and 3π/2 radians are 15.5 feet, 11.5 feet, and 10 feet, respectively.

What is the equation of a circle in parametric form?

The equation of a circle in parametric form is given by x=acosθ,y=asinθ.

We can use the equation for a circle in standard form:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

In this case, the center of the propeller is (0, 13) and the radius is 3. So the equation of the circle is:

x² + (y - 13)² = 9

We can use this equation to find the x and y coordinates of the tip of each propeller.

For the blade at π/6 radians, we can use the parametric equations for a circle:

x = r cos(t) + h

y = r sin(t) + k

where t is the angle in radians.

Substituting r = 3, h = 0, k = 13, and t = π/6, we get:

x = 3 cos(π/6) + 0 = 3√3/2

y = 3 sin(π/6) + 13 = 13 + 3/2 = 15.5

So the height of the tip of the propeller blade at π/6 radians is 15.5 feet.

Using the same method for the blades at 5π/6 and 3π/2 radians, we get:

Blade at 5π/6 radians:

x = 3 cos(5π/6) + 0 = -3√3/2

y = 3 sin(5π/6) + 13 = 13 - 3/2 = 11.5

Height of tip: 11.5 feet

Blade at 3π/2 radians:

x = 3 cos(3π/2) + 0 = 0

y = 3 sin(3π/2) + 13 = 10

Height of tip: 10 feet

Therefore, the heights of the tips of the propeller blades at π/6, 5π/6, and 3π/2 radians are 15.5 feet, 11.5 feet, and 10 feet, respectively.
