Answer:

11/130

Step-by-step explanation:

The number of people who use any facility is:

N = 65 + 51 + 44 − 15 − 14 − 10 − 2(1)

N = 119

So the number of people who don't use any facility is 130 − 119 = 11.

And the probability is 11/130.

Gillian pocket money is x, then Gillian  has \(5/12x\)left after spending on snacks and bus fare.

The term "spending" refers to the act of spending money to buy goods or services. It is the act of exchanging money for something, usually a product, service, or experience. Buying groceries, paying for transportation, or purchasing clothing are all examples of spending. To avoid debt and achieve your financial goals, it is critical to manage your spending wisely in personal finance.

If Gillian spends one-third of her pocket money on snacks and one-quarter on bus fare, she spends 7/12 of her pocket money on snacks and bus fare.

This means she only has \(1 - 7/12 = 5/12\) of her pocket money remaining.

As a result, if her pocket money is x, she has 5/12x left after paying for snacks and bus fare.

The probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

Total ways of choosing 3 out of 10 = C(10, 3) = 120

Total outcomes = 120

Total favorable outcomes = 3(Joseph, Heidi, and Katy)

Probability = 3/120 = 1/40

Thus, the probability that Joseph, Heidi, and Katy are chosen is 1/40 if three of the ten people in the Latin club are chosen at random to represent the club at a tournament option (G) is correct.

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given the equation x^2 = 2y.

The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:

To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].

Now we need to find the value of x that will minimize this expression.

We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.

Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T

he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The first four terms of the sequence are 2, 3, 5, and 8.

The position of a number in a sequence is indicated by a word in the sequence. For instance, the number two is the third term in the Fibonacci sequence 1, 1, 2, 5, 8,... The first "one" in the series is the first word. In mathematics, the letter n can be used to denote a sequence's terms.

Using the given formula, we can find the terms of the sequence as follows:

a(1) = 2 (given)

a(2) = 3 (given)

a(3) = a(2) + a(1) = 3 + 2 = 5

a(4) = a(3) + a(2) = 5 + 3 = 8

The probability that exactly 2 employees were over 50 if the dismissed employees were selected at random is 0.2048.

We have to determine the probability that exactly 2 employees were over 50 if the dismissed employees were selected at random. It is given that the town recently dismissed 6 employees to meet their new budget reductions. It is also given that the town had 4 employees over 50 years of age and 17 under 50 years of age. Therefore, total employees in the town = 4 + 17 = 21.

If we assume that all the employees have an equal probability of being selected, then the total number of ways of selecting 6 employees from 21 employees can be given by:21C6 = (21*20*19*18*17*16)/(6*5*4*3*2*1) = 54264Now, the number of ways of selecting exactly 2 employees over 50 from 4 employees over 50 can be given by:4C2 = (4*3)/(2*1) = 6Also, the number of ways of selecting exactly 4 employees under 50 from 17 employees under 50 can be given by:17C4 = (17*16*15*14)/(4*3*2*1) = 2380.

Therefore, the number of ways of selecting 2 employees over 50 and 4 employees under 50 from the total 6 employees can be given by:6C2 * 17C4 = (6*5/2*1) * (17*16*15*14/4*3*2*1) = 3246320.

Hence, the probability that exactly 2 employees were over 50 if the dismissed employees were selected at random is given by:3246320/54264 = 0.2048 (rounded to four decimal places).

y = mx + b

Where m is the slope of the line

b is the y intercept

y is the y coordinate

x is the x coordinate

The probability is\($\boxed{\frac{1}{3}}$.\)

To find the probability that the product of two numbers chosen from {3, 4, 5, 6} is a multiple of 9, we first need to determine the total number of possible pairs of numbers that can be chosen without replacement from this set.

There are \($\binom{4}{2} = 6$\) ways to choose two numbers from the set. These pairs are:

(3, 4), (3, 5), (3, 6), (4, 5), (4, 6), (5, 6)

Next, we need to determine which of these pairs have a product that is a multiple of 9. A number is a multiple of 9 if and only if it is divisible by 9, so the product of two numbers is a multiple of 9 if and only if at least one of the numbers is a multiple of 3.

From the set {3, 4, 5, 6}, only the numbers 3 and 6 are multiples of 3. Therefore, the pairs with a product that is a multiple of 9 are:

(3, 6), (6, 3)

Note that we have listed both (3, 6) and (6, 3) because the order in which the numbers are chosen does not matter.

Therefore, the probability that the product of two numbers chosen from {3, 4, 5, 6} is a multiple of 9 is:

\(\frac{number of pairs with product divisible by 9 }{total number of pairs} = \frac{2}{6} =\frac{1}{3}\)

2. Vertical Stretch.

3. Vertical Shrink.

Vertical translation is defined as the movement of a function's graph upward or downward. In this, the function's form doesn't change. The graph moving or shifting along the y-axis is another name for it.

What is Vertical Stretch?

When a base graph is multiplied by a particular factor greater than 1, vertical stretch happens. As a result, the graph is stretched outward while keeping the input values (or x).

What is Vertical Shrink?

The y-values are multiplied by a value between 0 and 1, which causes them to travel in the direction of the x-axis. This is referred to as a vertical shrink and tends to make the graph flatter.
