Step-by-step explanation:

The Order of Operations is very important when simplifying expressions and equations. The Order of Operations is a standard that defines the order in which you should simplify different operations such as addition, subtraction, multiplication and division.

This standard is critical to simplifying and solving different algebra problems. Without it, two different people may interpret an equation or expression in different ways and come up with different answers. The Order of Operations is shown below.

Parentheses and Brackets -- Simplify the inside of parentheses and brackets before you deal with the exponent (if any) of the set of parentheses or remove the parentheses.

Exponents -- Simplify the exponent of a number or of a set of parentheses before you multiply, divide, add, or subtract it.

Multiplication and Division -- Simplify multiplication and division in the order that they appear from left to right.

Addition and Subtraction -- Simplify addition and subtraction in the order that they appear from left to right.

Before we begin simplifying problems using the Order of Operations, let's examine how failure to use the Order of Operations can result in a wrong answer to a problem.

Without the Order of Operations one might decide to simplify the problem working left to right. He or she would add two and five to get seven, then multiply seven by x to get a final answer of 7x. Another person might decide to make the problem a little easier by multiplying first. He or she would have first multiplied 5 by x to get 5x and then found that you can't add 2 and 5x so his or her final answer would be 2 + 5x. Without a standard like the Order of Operations, a problem can be interpreted many different ways

We cannot combine the variable terms before using the distributive property when solving the equation as it will results in wrong answer.

What is distributive property of multiplication over addition ?

If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.

Here the expression given is :

7(x+5)-x=42

Answer:

0.92

Step-by-step explanation:

a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)

P(A) = 0.42

P(B) = 0.58

P(A|B) = 0.14

Step 1

P(A|B) × P(B) = 0.14 × 0.58

= 0.0812

The probability that at least one of the stocks will rise in price

P(A) + P(B) - 0.0812

0.42 + 0.58 - 0.0812

= 1 - 0.0812

= 0.9188

Approximately to 2 decimal place = 0.92

Answer:

y = .25x + 3

Step-by-step explanation:

First, you need to find the slope of the equation which is change in y over change in x. For this question, it's (6-2)/(12-(-4)) = 4/16 = 1/4

After, choose a point and plug it into the point slope formula: y - y0 = m(x - x0)

I chose the first point.

You should get y - 2 = .25(x + 4)

y -2 = .25x + 1

y = .25x + 3

To use the slope-intercept form, we need a slope.

Recall that the slope of a line m = (y2 - y1) / (x2 - x1). We are given the coordinates of two points, both of which lie on the line (the line passes through them): (-4,2) and 12,6).

So given these two points, let's let x1 = -4 and y1 = 2; and let's let x2 = 12 and y2 = 6. Substituting these values into the equation for the slope of a line, we get

m = (6 - 2) / [12 - (-4)] = 4 / 16, or m = 1/4

So now we have the slope, and we can use the point-slope form of the equation of a line to help us determine the y-intercept. The point-slope form is y - y1 = m * (x - x1)

Substituting our slope m = 1/4 and either one of the points (let's say the first point), we have

y - 2 = 1/4 * [x - (-4)] = 1/4 * (x + 4)

Now add 2 to both sides of this equation, and we have y = 1/4 * (x + 4) + 2

Using the distributive law, we can further reduce this to y = 1/4 * x + 1 + 2, or y = 1/4 * x + 3

Finally, the y-intercept of a line is where the line intersects the y-axis or, mathematically speaking, where the x-coordinate is equal to zero. So let's let x = 0 in the equation above, and solve for y. Substituting x = 0 into the equation for our line, we now have

y = 1/4 * 0 + 3 = 3

So our y-intercept is 3 (three). Now we can write the equation for our line in the slope-intercept form:

y = m * x + b, where m is the slope and b is the y-intercept. Substituting for m and b, we get

y = 1/4 * x + 3.

So the equation in slope-intercept form of the line that passes through points (-4,2) and (12,6) is

y = 1/4 * x + 3

(To check your answer, substitute either one of the points into the equation...)

Answer:

[tex]Area = 143cm^2[/tex]

Step-by-step explanation:

Given

Shape: Opening of a circular vase

[tex]Diameter =13.5cm[/tex]

[tex]\pi = 3.14[/tex]

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

[tex]Area = \pi r^2[/tex]

Solve for radius (r)

[tex]r = \frac{d}{2}[/tex]

[tex]r = \frac{13.5\ cm}{2}[/tex]

[tex]r = 6.75\ cm[/tex]

Substitute 6.75 for r in [tex]Area = \pi r^2[/tex]

[tex]Area = 3.14 * 6.75^2[/tex]

[tex]Area = 143.06625[/tex]

Step-by-step explanation:

The snowball is spherical in nature

The total surface area of the ball = 4πr²

Or 4π(d/2)²

S = 4πd²/4

S = πd²

d is the diameter of the ball

The rate at which the area is decreasing is expressed as;

dS/dt = dS/dd • dd/dt

dd/dt is the rate at which the diameter is decreasing

dS/dd = 2πd

dS/dt = 2πd • dd/dt

dS/dt = 2π(9) • dd/dt

8 = 18π•dd/dt

dd/dt = 8/18π

dd/dt = 4/9(3.14)

dd/dt = 4/28.26

dd/dt = 0.1415cm/min

Hence the diameter is decreasing at the rate of 0.1415cm/min
