Step-by-step explanation:

The least amount of money she needs to deposit to avoid a fee is;  $16.62

We are given;

Amount Keisha has in her checking account = $585.43

Minimum balance to be maintained = $300

Check written = $302.05

Now, if x represents the variable, that would be used for the least amount of money she needs to deposit to avoid a fee, then the inequality is;  $585.43 - $302.05 + x ≥ $300

$283.38 + x ≥ $300

Subtract 283.38 from both sides to get;

x ≥ $16.62

Thus, the least amount of money she needs to deposit to avoid a fee is;  $16.62

What is Symbolic notation?

Symbolic notation is a way of representing the counting numbers by writing a simple symbol.

Now,

For the false statement we use the symbol ( ~ ).

If in the statement the word ''or'' is present then we use the symbol ''∧'' and for the word ''and'' we use the symbol ''∨''.

Hence,

For the statement;

a. Atlanta is the capital of Georgia, or there are 3 feet in a yard.

Both are truth and with the word ''or'', then the symbolic notation,

⇒ p ∧ q

For the statement;

b. Atlanta is the capital of Georgia and there are not 3 feet in a yard.

One statement is truth and second is false , then the symbolic notation,

⇒ p ∨ ~ q

For the statement;

c. Atlanta is not the capital of Georgia, or there are 3 feet in a yard.

First statement is false and second is truth , then the symbolic notation,

⇒ ~ p ∧ q

For the statement;

d. Atlanta is the capital of Georgia, and there are 3 feet in a yard.

Both are truth and with the word ''and'', then the symbolic notation,

⇒ p ∨ q

So, The symbolic notation are;

If the scores on an exam follow an approximately normal distribution with a mean of 76.4 and a standard deviation of 6.1 points, then the minimum score needed to be in the top 7% is calculated to be 85.404.

This type of problem can be categorized as a normal distribution problem and can be solved with the help of z-score.

If we consider Z = standard score,

μ = mean

σ = standard deviation

Then the z-score to figure out the lowest score to be in the top 7% is given as,

Z = x - μ / σ

If the p-value is known, the z-score can be found with the help of the standard table.

As the minimum score to be in the top 7% is to be determined, p-value = 0.07

The z-score that corresponds to the p-value of 0.07 is 1.476 in the standard table.

Hence,

1.476 = x - 76.4 ÷ 6.1

1.476 × 6.1 = x - 76.4

1.476 × 6.1 + 76.4 = x

9.004 + 76.4 = x

x = 85.404

Therefore, 85.404 is the minimum score that is needed to be in the top 7%.

Answer:

163 degrees

Step-by-step explanation:

163 degrees is equal to y

Z = x

The measure of angle y is 163° and the measure of angle x and z is 17 degrees.

Given that:

Two lines are intersected with each other.

It is required to find the measure of angles x, y, and z.

The angles formed on the opposite side of the intersecting line are called vertical angles.

Also, by the Vertical Angles Theorem, the vertical angles formed are always equal.

Here, y is vertical to the given measure of 163°.

So, y = 163°.

Now, x and y are the angles formed along a line.

So, they are linear pair of angles.

Linear pair of angles are supplementary.

So, x + y = 180

x = 180 - 163

  = 17°

Also, x and z are vertical angles.

So, z = 17°

Hence, x = 17°, y = 163°, and z = 17°.

Answer: Exercise 8 module 3 Describe the graph of the Celsius - Fahrenheit relationship is    F =  8C + 3  and     C = (F-3) / 8

Step-by-step explanation:

Celsius and Fahrenheit are two scales used to measure temperature. The temperature in the centigrade scale will be expressed in degrees Celsius. The temperature in the Fahrenheit scale will be expressed in degrees Fahrenheit. The relation between Celsius and Fahrenheit is proportional. Both have a different freezing point of water and both follow the varied unit difference between each scale.

Celsius to Fahrenheit

The conversion from Celsius to Fahrenheit can be mathematically expressed as-

                            F = [ (9/5) x C ] + 32

Where,

F is the temperature in Fahrenheit.

C is the temperature on the Centigrade scale.

Fahrenheit to Celsius

The conversion from Fahrenheit to Celsius can be mathematically expressed as-

                          C = (5/9) [ (F-32) ]

Where,

F is the temperature in Fahrenheit.

C is the temperature on the Centigrade scale.

Units of Celsius and Fahrenheit :

The units of temperature scale are useful in differentiating temperatures from one scale to another.

The temperature on the Celsius scale is denoted by °C

The temperature on the Fahrenheit scale is denoted by °F

Using linear function concepts, the graph of the Celsius-Fahrenheit relationship is linear with an intercept of 3 and slope of 8 module.

A linear function is modeled by:

                    y = mx + b

where,    m is the slope

so, we can write,

                    F =  8C + 3

we can also express the Celsius in terms of Fahrenheit :

                     8C = F - 3

                      C = (F-3) / 8

Therefore,

Exercise 8 module 3 Describe the graph of the Celsius - Fahrenheit relationship is    F =  8C + 3  and    C = (F-3) / 8.
