The value of the expression is the same as the second option: !a || (b & !c).

Boolean variables are variables that can have only one of two possible values: true or false. They are named after the 19th-century mathematician George Boole, who developed a system of logic based on binary values. In computer programming, boolean variables are commonly used to represent conditions or states that can be either true or false, such as whether a certain condition is met or whether a certain task has been completed.

The expression !(a & !(b & !c)) can be simplified using De Morgan's laws and distributive property to obtain:

!(a & !(b & !c)) = !a || (b & !c)

Therefore, the value of the expression is the same as the second option: !a || (b & !c).

So the temperature in City A was 8A C and the temperature in City B was y = x + 1 = 8 + 1 = 9A C.

The problem can be solved by setting up an equation using the information given. Let's call the temperature of City A "x" and the temperature of City B "y". We can then write two equations based on the information given:

4x = 3y + 8

x - 2y = -3

We can use substitution to solve for one of the variables and then use that information to solve for the other. For example, we can substitute 3y + 8 for 4x in the second equation:

x - 2y = -3

x - 2y = 3y + 8 - 3

x - 2y = 3y + 5

x - 5y = 5

We can then solve for y by multiplying both sides of the equation by -1/5:

-5x + 5y = -5

5y = 5x + 5

y = x + 1

We can then substitute this expression for y into one of the original equations and solve for x:

4x = 3(x + 1) + 8

4x = 3x + 3 + 8

x = 8

So the temperature in City A was 8A C and the temperature in City B was y = x + 1 = 8 + 1 = 9A C.

The new perimeter of the quadrilateral is  157.2 ft

Consider the following diagram.

We name the quadrilateral ABCD such that side AB = 12.2 ft, side BC = 16 ft, side AD = 12 ft

Let us assume that the perpendicular or height be DE = 12 ft

From figure we can observe that side AB = side CD

So, side CD = 12.2 ft

The quadrilateral is enlarged by a scale factor of 3

so, the dimensions of the new quadrilateral would be,

A'B' = 3 × AB

     = 36.6 ft

So, C'D' = 36.6 ft                  ............(as AB = CD)

B'C' = 3 × BC

B'C' = 48 ft

And A'D' = 3 × AD

A'D' = 36 ft

We know that the perimeter of quadrilateral is the sum of all the four sides.

So, the perimeter of new quadrilateral A'B'C'D' would be,

A'B' + B'C' + C'D' + A'D'

= 36.6 + 48 + 36.6 + 36

= 157.2 ft

Answer:

The probability of rolling a 1 or a 4 on a single roll of the number cube is 2/6, or 1/3. So the expected number of times the number cube will land with a 1 or a 4 on the top face after 400 rolls is 400 * 1/3 = 133.33.

The range that contains this expected value is roughly between 130 and 140, so a good prediction for the number of times the number cube will land with a 1 or a 4 on the top face is between 130 and 140.

By evaluating both equations in x = 8 we will see that the hawk will be closer to the ground.

We know that the height of the hawk is modeled by:

y=−20x+350

And the height of the eagle is modeled by:

To determine if a line is parallel or perpendicular, we can place each line on a sloped intersection shape (y = mx + b) and observe the slope m of each line. Equal slopes result in parallel lines. If the slope is multiplied by -1, then the line is vertical.

Parallel Lines:

Two or more lines that lie in the same plane and do not intersect are called parallel lines. They are equidistant from each other and have the same slope. A straight line equation is usually written in the form of a slope intercept represented by the equation y = mx + b. where "m" is the slope and "b" is the y-intercept. The "m" value defines the slope and tells how steep the line is.

Perpendicular Lines:

A vertical line or perpendicular line is two separate lines that intersect at an angle of 90° to each other. These are straight lines known as perpendiculars that meet each other at certain angles (right angles).

We have already seen what a vertical line looks like. If a shape has an "L" shape, its vertex angles are right angles. Vertical lines always intersect each other, but not all intersecting lines are always perpendicular to each other.

Two main properties of vertical lines:

1. Perpendicular lines always intersect or intersect each other.

2. The angle between two vertical lines is always 90°.

The standard deviation is used more frequently then the variance because  standard deviation is more stable and less sensitive to outliers.

The Standard Deviation and Variance are defined as two closely related measures of the spread or dispersion of a set of data.

The Variance is defined as average of squared differences from mean, while Standard Deviation is square root of variance.

The reason why the standard deviation is used more frequently than  variance is because the standard deviation is expressed in same units as the original data, whereas  the variance is expressed in squared units.

For Example, if we measure  heights of a group of people in inches, the standard deviation will be expressed in inches, whereas variance will be expressed in square inches.

The only value of x from the set {7, 9, 36} that makes the inequality 2x < 18 true is x = 7.

We can use substitution to find which value of x makes the inequality 2x < 18 true by trying each value in the set {7, 9, 36} one by one.

Let's start with x = 7:

2x = 2(7) = 14

14 < 18 is true, so x = 7 satisfies the inequality.

Next, let's try x = 9:

2x = 2(9) = 18

18 < 18 is not true, so x = 9 does not satisfy the inequality.

Finally, let's try x = 36:

2x = 2(36) = 72

72 < 18 is not true, so x = 36 does not satisfy the inequality.

Therefore, the only value of x from the set {7, 9, 36} that makes the inequality 2x < 18 true is x = 7.

When Y directly varies with X, the direct variation equation is X = 2.

A direct variation is a relationship between two variables when their ratio is constant. One variable is said to vary in direct proportion to another. Y = kx, where k is the variational constant, is the formula for direct variation. If y varies in direct proportion to x and y = 6 when x = 2, the variational constant is k = = 3. Consequently, y = 3x is the equation that describes this direct variation.

If y directly correlates with x, we can apply the direct variation formula as follows:

y = kx

where k is the proportionality constant.

We may utilise the y and x values provided to find k:

y = kx

16 = k(4)

Solving for k, we get:

k = 16/4 = 4

Now we can use the value of k to find x when y = 8:

y = kx

8 = 4x

Dividing both sides by 4, we get:

x = 2

Answer:

Lisa would need to score 97 on her 5th test.

Step-by-step explanation:

If Lisa has an average score of 82 on 4 tests, then the total sum of her scores would be 82 multiplied by 4, which is equal to 328.

If she wants an average final score of 85 over 5 tests, then the total sum of her scores needs to be 425 (i.e. 85 multiplied by 5).

To determine what she needs to get on her 5th test we need to subtract 328 from 425.

425 - 328 = 97

Suri has 10.00, and Savi has 3 times as much, or 30.00.

What is algebraic expression?

When we use numbers and words to solve a mathematical problem, we are using algebraic expressions.

Let's use algebra to solve the problem.

Let's say Suri has x amount of money. Then we know that Savi has 3 times as much money, or 3x. We also know that together they have 40.00. So we can write an equation:

x + 3x = 40

Simplifying this equation, we get:

4x = 40

Dividing both sides by 4, we get:

x = 10

So Suri has 10.00, and Savi has 3 times as much, or 30.00.

To check, we can verify that their total is 40.00:

10 + 30 = 40

The cost to print 50 photos is $12.50

What is proportion?

The proportion formula is used to determine whether or not two ratios or fractions are equal.

We can use a proportion to find the cost to print 50 photos based on the cost to print 20 photos. Since Ms. Morris charges $5.00 to print 20 photos, we can set up the proportion:

[tex]\frac{cost \ of \ 20\ photos}{number \ of\ photos } =\frac{cost \ of \ 50 \ photos}{number\ of \ photos}[/tex]

Plugging in the given values, we get:

$5.00 / 20 photos = x / 50 photos

Simplifying, we can cross-multiply to get:

20 photos * x = $5.00 * 50 photos

Multiplying and simplifying further, we get:

20x = $250.00

Dividing both sides by 20, we get:
