Alex initially had 60 two pence coins.

Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols. It is used to solve problems and represent mathematical relationships and formulas. In algebra, letters and other symbols are used to represent numbers and quantities, allowing us to express mathematical relationships and patterns in a more general and abstract way.

In mathematics, simplification refers to the process of reducing an expression or equation to a simpler form. This is typically done by applying mathematical operations or rules to the expression or equation to eliminate unnecessary terms, factors, or operations.

For example, if we have the expression (x^2 + 4x + 4)/(x + 2), we can simplify it by factoring the numerator and canceling out the common factor with the denominator. This gives us (x + 2), which is a simplified form of the original expression.

In the given question,

Let's start by using some algebra to solve the problem.

Let's say that Alex initially had x two pence coins. After swapping half of them for 10p coins, she would have x/2 ten pence coins. We can use this information to set up an equation relating the value of her coins to the total amount of money she ended up with:

0.02x + 0.10(x/2) = 4.20

Simplifying this equation, we get:

0.02x + 0.05x = 4.20

0.07x = 4.20

x = 60

So Alex initially had 60 two pence coins. Checking our answer, we can see that she swapped half of them for 30 ten pence coins. The value of her 60 two pence coins is 0.02 x 60 = £1.20, and the value of her 30 ten pence coins is 0.10 x 30 = £3.00. Together, these add up to £4.20, as required.

The distribution of Sn + Tm is a binomial distribution with parameters (n+m, p).

This can be proved using the fact that the sum of independent binomial random variables follows a binomial distribution with the sum of the number of trials and the same probability of success.



Let X ~ Binomial(n, p) and Y ~ Binomial(m, p) be independent random variables representing the number of heads in the first n coin tosses and the last m coin tosses, respectively.

Then, the sum of X and Y, Z = X + Y, follows a binomial distribution with parameters (n+m, p).

The probability mass function of Z can be written as:

P(Z = k) = P(X + Y = k) = ∑ P(X = i) * P(Y = k-i) for i = 0 to k

Since X and Y are independent, we can write:

P(Z = k) = ∑ P(X = i) * P(Y = k-i) = ∑ (n choose i) * p^i * (1-p)^(n-i) * (m choose k-i) * p^(k-i) * (1-p)^(m-k+i)

Simplifying the above equation, we get:

P(Z = k) = (n+m choose k) * p^k * (1-p)^(n+m-k)

Therefore, Z ~ Binomial(n+m, p).

As a result, the distribution of Sn + Tm has the parameters (n+m, p) of a binomial distribution.

The profits exist the same (slope) but the y-intercept is more increased than the actual diagram.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

The slope-intercept form of a linear equation is where one side includes only "y"

2x+ 3y= 1470

y= -2/3 x + 490

Hence, the y-intercept exists at 490 and the slope is -2/3x.

If you put your hand on a hot stove and got burnt, it is a natural response to remove your hand from the stove to prevent further injury. However, if you choose to repeatedly put your hand back on the stove even after being burnt, you will continue to experience pain and potentially cause further damage to your skin and tissues.

Repeatedly exposing yourself to the source of the burn will not change the fact that it is hot and causing damage to your skin. In fact, each time you touch the hot surface, you are likely to make the burn worse, as the heat will continue to damage your skin and tissues.

Additionally, repeated exposure to the hot stove may lead to nerve damage, which can result in a loss of sensation in your hand, making it harder to recognize when you are in danger of burning yourself in the future.

It is important to listen to your body's natural responses to pain and remove yourself from harmful situations. In the case of a burn, it is best to seek immediate medical attention and follow proper first aid procedures to minimize damage and promote healing.

The distance between home plate and second base in a Major League Baseball field is approximately 127.28 feet.

The distance from home plate to second base in a major league baseball field is 127 feet and 3⅜ inches, or approximately 127.28 feet. This is because the distance between each base (from home to first, first to second, etc.) is 90 feet, and the diagonal of a square is found by using the Pythagorean theorem: a² + b² = c². In this case, a and b are both 90 feet, so the equation becomes 90² + 90² = c². Simplifying and solving for c gives us c = 127.28 feet. Therefore, the distance from home plate to second base is 127.28 feet.

Answer:

Let x be the amount (in liters) of the 5% acetic acid solution to be added.

Let y be the amount (in liters) of the 10% acetic acid solution to be added.

The system of equations is:

x + y = 2 (the total amount of solution is 2 liters)

0.05x + 0.10y = 0.07(2) (the amount of pure acetic acid in the final solution is 7% of 2 liters)

Simplifying the second equation:

0.05x + 0.10y = 0.14

5x + 10y = 14 (multiplying both sides by 100)

We now have a system of two equations with two variables. We can solve it by substitution or elimination. Here, we'll use substitution:

x + y = 2 => x = 2 - y (subtracting y from both sides)

Substituting x in the second equation:

5(2 - y) + 10y = 14 (replacing x by 2 - y)

10 - 5y + 10y = 14

5y = 4

y = 0.8

So the photographer should add 0.8 liters of the 10% acetic acid solution and 2 - 0.8 = 1.2 liters of the 5% acetic acid solution. We can check that this solution satisfies both equations:

0.05(1.2) + 0.10(0.8) = 0.06 + 0.08 = 0.14

1.2 + 0.8 = 2

Therefore, the answer is:

The photographer should add 0.8 liters of the 10% acetic acid solution and 1.2 liters of the 5% acetic acid solution.

Answer:

We can use the concept of proportion to estimate the total number of sweets in the jar.

Let's represent the total number of sweets in the jar by "x". We know that 90 of these are pear drops. So the proportion of pear drops in the jar is 90/x.

Leona takes a random sample of 70 sweets from the jar and finds that 22 of these are pear drops. So the proportion of pear drops in the sample is 22/70.

We can assume that the proportion of pear drops in the sample is roughly equal to the proportion of pear drops in the jar. Therefore, we can set up a proportion and solve for "x":

90/x = 22/70

Cross-multiplying, we get:

22x = 90 * 70

Dividing both sides by 22, we get:

x = 90 * 70 / 22

Using a calculator, we get:

x ≈ 287

Therefore, an estimate for the total number of sweets in the jar is 287, rounded to the nearest integer.

I is convergent.

The Comparison Theorem is an important tool in the study of Probability and Statistics, as it allows us to determine the convergence or divergence of improper integrals without directly evaluating them. In this case, we are asked to determine the convergence or divergence of the improper integral I=∫ 2 [infinity] ​ e −x 2 dx using the Comparison Theorem.

1. To justify the inequality e −2x ≥e −x 2 for all x≥2, we can take the natural logarithm of both sides of the inequality to get -2x ≥ -x^2. Since x≥2, we can divide both sides of the inequality by -x to get 2 ≤ x, which is true for all x≥2. Therefore, the inequality e −2x ≥e −x 2 is true for all x≥2.

2. To evaluate ∫ 2 [infinity] ​ e −2x dx, we can use the substitution u=-2x, du=-2dx. This gives us ∫ 2 [infinity] ​ e −2x dx = ∫ -4 [-infinity] ​ (1/2)e^u du = (1/2)(-e^u)|-4 [-infinity] = (1/2)(-e^-4 + e^[infinity]) = (1/2)(-e^-4 + 0) = (1/2)e^-4.

3. To determine if I is convergent or divergent, we can use the Comparison Theorem. Since e −2x ≥e −x 2 for all x≥2, and ∫ 2 [infinity] ​ e −2x dx is convergent, then ∫ 2 [infinity] ​ e −x 2 dx is also convergent by the Comparison Theorem. Therefore, I is convergent.

The minimum value is 24

To find the minimum value of z=7x+3y, we must use the given constraints to determine the values of x and y.

First, solve 4x + 6y ≥ 24. Rearrange the equation to solve for x: x ≥ (24 - 6y) / 4.

Next, solve x + 6y ≥ 12. Rearrange the equation to solve for y: y ≥ (12 - x) / 6.

Using the two equations, determine the possible values of x and y:
If y = 0, then x = 6
If x = 0, then y = 2

Substitute the possible values of x and y into the equation z = 7x + 3y and find the minimum value:
z = 7(6) + 3(0) = 42
z = 7(0) + 3(2) = 24

Therefore, the minimum value of z is 24.

To multiply each term by the LCD, we need to first find the LCD of the given expression. The LCD of the expression is the product of the denominators, which is x(x-4)(x-3).

Now, we can multiply each term by the LCD to get rid of the denominators:

A[x(x-4)(x-3)]/(x) * x(x-4)(x-3) = A(x-4)(x-3)

B[x(x-4)(x-3)]/((x-4)) * x(x-4)(x-3) = B(x)(x-3)

C[x(x-4)(x-3)]/((x-3)) * x(x-4)(x-3) = C(x)(x-4)
