To find the probability of selecting the letter "C" or the coin landing tails up, we need to calculate the probability of each event individually and then add the probabilities of the two events together.

The probability of selecting the letter "C" is:

1/5

This is because there are 5 letters in total, A, B, C, D, and E, and "C" is one of them, so the probability of selecting "C" is 1/5.

The probability of the coin landing tails up is:

1/2

This is because there are two possible outcomes when flipping a coin, heads or tails, and since the coin is fair, the probability of getting heads or tails is 1/2.

To find the combined probability of the two events we need to add them together using the rule of "or" in probability which is defined as:

P(A or B) = P(A) + P(B) - P(A and B)

However in this case A and B are mutually exclusive events, meaning they can't happen at the same time. There is no way to have "C" and coin landing tails up at the same time. Then we don't have to subtract P(A and B)

Therefore, the probability of selecting the letter "C" or the coin landing tails up is:

1/5 + 1/2 = 2/5 + 1/2 = 7/10

So the probability of selecting the letter "C" or the coin landing tails up is 7/10

The scale factor of the rectangle and its copy is [tex]\frac{2}{3}[/tex].

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

The rectangle on right hand side is the scaled copy of the original rectangle. The scaled version of the rectangle is given as follows:

[tex]\frac{42}{63} \text{ and } \frac{15}{\frac{45}{2} } = \frac{30}{45}[/tex]

Rationalize the factors to find the scale factor.

Rationalize the factor [tex]\frac{42}{63}[/tex] by multiplying and dividing by 45.

[tex]\frac{(42)(45)}{(63)(45)}[/tex]

[tex]\frac{1890}{2835}[/tex]

Rationalize [tex]\frac{30}{45}[/tex] by multiplying and dividing by 63.

[tex]\frac{(30)(63)}{(45)(63)}[/tex]

[tex]\frac{1890}{2835}[/tex]

Scale factor = [tex]\frac{1890}{2835} = \frac{2}{3}[/tex]

Hence the scale factor of the rectangle and its copy is [tex]\frac{2}{3}[/tex].

y = (-4/11)x + 5.27 is the equation that passes through each pair of points (9,2) (-2,6).

A group of numbers and variables without an equal sign are known as a numerical expression. A set of numbers and variables with an equal sign is referred to as an equation.

Once you are familiar with these terms, you will realise that an equation is just two expressions joined by an equal sign. You can also write expressions, equations, and simplify equations.

To find an equation of the line that passes through each pair of points (9,2) (-2,6) we need to find slope and convert it to y-intercept form

Slope formula = y - y₁ = m(x - x₁)

Putting the values in the formula we get

2 - 6 = m(9 - (-2))

-4 = m(11)

m = -4/11

As we have found slope, we can find the slope intercept form i.e.

y - 2 = -4/11(x -9)

y = (-4/11)x + 3.27 + 2

y =  (-4/11)x + 5.27

In this problem we need to determine the equation that described the line segment AB, whose endpoints are points within other two line segments. The location of a point can be found by means of the following formula:

P''(x, y) = P(x, y) + k · [P'(x, y) - P(x, y)], 0 ≤ k ≤ 1

Where:

First, determine the locations of endpoints A and B:

A(x, y) = (- 2, 3) + 0.5 · [(6, - 1) - (- 2, 3)]

A(x, y) = (- 2, 3) + 0.5 · (8, - 4)

Using the sine rule, sin a/A = sin b/B in this instance, we can determine the distance between P and R.

Sin angle PQR/PR is equal to Sin angle QRP/PQ.

We are aware that the QRP angle is 45° because:

Since it is an alternative interior angle, angle NPR is 75°.

Since 75° – 60° = 15, the angle QPR would be 15°.

As a result, angle QRP would be 45° since 180° – 120° – 15° = 45°.

When we know the angle QRP, we can quickly calculate the PR by entering the values into a calculator.

Answer: The interest rate is 0.16 or 16% ✅

Step-by-step explanation:

The interest rate is the percentage of the principal (the initial amount of money) that is paid as interest over a certain period of time. To find the interest rate in this scenario, we can use the formula:

Interest = Principal x Interest Rate x Time

In this case:

Interest = $12,800

Principal = $40,000

Time = 4 years

So we can set up the equation:

12800 = 40000 x Interest Rate x 4

To find the interest rate, we can divide both sides of the equation by 40000 x 4, which gives us:

12800 / (40000 x 4) = Interest Rate

We can simplify this fraction:

0.16 = Interest Rate

So the interest rate is 0.16 or 16%.

When Todd made $12,800 in interest by placing $40,000 in a savings account with simple interest for 4 years, the interest rate was 7.5%.

Simple interest is a formula for calculating the amount of interest that will be charged on a sum of money at a specific rate and during a specific time frame.

In contrast to compound interest, where the interest of one year's principal is added to the principal of the following year to calculate the interest, the principal sum in the case of simple interest stays the same.

Simple Interest = [tex]$ \frac{ \text P \times \text R \times \text T}{100}[/tex]

where,

P = Principal,

R = Rate of Interest in % per annum, and

T = Time, in years

Here given that,

Todd made $12,800 in interest, i.e. Simple Interest = 12,800

By placing $40,000 in a savings account, i.e. Principal = 40,000

with simple interest for 4 years, i.e. Time = 4 years

To find, interest rate

Substitute the data into the simple interest formula

[tex]$ \Rightarrow 12,800 = \frac{40,000 \times \text R \times 4}{100}[/tex]

[tex]$ \Rightarrow \text R = \frac{ 12,000 \times 100}{40,000 \times 4}[/tex]

[tex]$ \Rightarrow \text R = \frac{1,200,000}{160,000}[/tex]

⇒ R = 7.5%
