Step-by-step explanation:

step 1

100%/the total number = percent for one probability

100/5 = 20%

2 and 4 is even.

total even number * percent for one probability = total percent for even number

20% * 2 = 40%

therefore total even number is 40%

The probability is:

Step-by-step explanation:

Remember the formula for probability:

\(\boxed{\!\!\boxed{\bold{Probability=\frac{Favourable~outcome}{total~outcomes}\quad}}\!\!}\)

In this case, the favourable outcome (an even number) is 2, because there are only 2 even numbers in the set.

As for the total outcomes, there are 5 of them, because we have 5 numbers total.

So the probability of choosing an even number is 2/5.

The number is 280

In mathematics, Least Common Multiple is referred to by its entire name, whereas Highest Common Factor is its complete name. The L.C.M. defines the least number that is exactly divisible by two or more numbers, whereas the H.C.F. describes the biggest factor existing between any given pair of two or more numbers. LCM is also known as the Least Common Multiple (LCM), and HCF is also known as the Greatest Common Factor (GCF).

Two key techniques—the division method and the prime factorization approach—can be used to determine H.C.F. and L.C.M.

So we need to find the LCM of 2,5 and 7. Furthermore, we need to find multiply the LCM with a number which can make its sum of digits equal to 10.

LCM of 2,5 and 7 is 70

70 x 4 = 280

Sum of digits of 280 is 10, which is also less than 500

The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.

Recall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.

A number's absolute value can be conceived of as its distance from zero along the real number line.

So, given  |x| + 3 > 3

Add minus three to both sides

|x| + 3  + (-3) > 3 + (-3)

|x|  > 0

Thus, the absolute value of x is

x > 0 or x < -0

put in the form of inequality, we have

x > 0 or x < 0

Hope this helps!

Answer:

\(r=\dfrac{5\sqrt{2}}{4}}\:i\:,\quad \;\;r=-\dfrac{5\sqrt{2}}{4}}\:i\)

Step-by-step explanation:

To solve the given equation, rearrange the equation to isolate r.

Given equation:

\(0=-16r^2-50\)

Add 16r² to both sides of the equation:

\(0+16r^2=-16r^2-50+16r^2\)

     \(16r^2=-50\)

Divide both sides of the equation by 16:

\(\dfrac{16r^2}{16}=\dfrac{-50}{16}\)

   \(r^2=-\dfrac{25}{8}\)

\(\textsf{For\;\:}x^2=f\left(a\right)\textsf{\:the\:solutions\:are\:\:}x=\pm\sqrt{f\left(a\right)}\)

\(r=\pm\sqrt{-\dfrac{25}{8}}\)

\(\textsf{Apply\;the\:radical\:rule:}\;\:\sqrt{-a}=\sqrt{a}\sqrt{-1}\)

\(r=\pm\sqrt{\dfrac{25}{8}}\sqrt{ -1}\)

\(\textsf{Apply\;the\:imaginary\:number\:rule:}\;\:\sqrt{-1}=i\)

\(r=\pm\sqrt{\dfrac{25}{8}}\:i\)

\(\textsf{Apply\;the\:radical\:rule:}\:\:\sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}},\:\quad \:a\ge 0,\:b\ge 0\)

\(r=\pm\dfrac{\sqrt{25}}{\sqrt{8}}\:i\)

Simplify the numerator and denominator of the fraction:

\(r=\pm\dfrac{5}{2\sqrt{2}}\:i\)

Rationalise the denominator by multiply the numerator and denominator by √2:

\(r=\pm\dfrac{5\cdot\sqrt{2}}{2\sqrt{2}\cdot \sqrt{2}}\:i\)

\(r=\pm\dfrac{5\sqrt{2}}{4}}\:i\)

Therefore, the solutions to the given equation are:

\(r=\dfrac{5\sqrt{2}}{4}}\:i\:,\quad \;\;r=-\dfrac{5\sqrt{2}}{4}}\:i\)

In a function, the relationship between the dependent and independent variables is represented by a "mathematical rule or equation". This rule defines how the value of the dependent variable changes based on the value of the independent variable.

The mathematical representation of this relationship is typically expressed as y = f(x), where "y" represents the dependent variable, "x" represents the independent variable, and "f" denotes the function.

The function provides a systematic way to determine the value of the dependent variable for any given value of the independent variable. It establishes a mapping between the two variables, where each input value of the independent variable corresponds to a unique output value of the dependent variable.

The function can take various forms, such as linear, quadratic, exponential, logarithmic, or trigonometric, depending on the nature of the relationship between the variables.

Functions play a fundamental role in mathematics, science, and various fields of study. They allow us to analyze and model real-world phenomena, make predictions, and understand the behavior of systems.

By examining the function's properties, such as its slope, intercepts, and shape, we can gain insights into how the dependent variable changes in response to changes in the independent variable.

Answer:

-2 1/3 - (-5) = -2 1/3 + 5

To add these two numbers, we need to find a common denominator. The common denominator of 3 and 1 is 3.

-2 1/3 can be written as -7/3 using the rule that a mixed number is equal to the sum of the whole number and the fraction.

So, we have:

-7/3 + 5

To add these two fractions, we need to find a common denominator. The common denominator of 3 and 1 is 3.

-7/3 can be written as -7/3 x 1/1 = -7/3.

So, we have:

-7/3 + 15/3 = 8/3

Therefore, -2 1/3 - (-5) = 8/3.

Answer: 72.36

Step-by-step explanation:

To find the total amount of salt in the bowl after Omar poured 13.2 grams, we need to add the initial amount of salt in the bowl to the amount of salt Omar added.

The initial amount of salt in the bowl was 59.16 grams.

Omar added 13.2 grams of salt to the bowl.

To find the total amount of salt in the bowl now, we add these two amounts: 59.16 + 13.2 = 72.36

Therefore, the bowl contains 72.36 grams of salt now.

Answer:

5 feet + 12 inches = 2 yards

48 inches = 1 foot + 1 yard

5 feet = 3 feet + 24 inches

Step-by-step explanation:

To help solve these equations, you must know how to convert feet to inches, inches to yards, etc. Use the information below:

1 feet = 12 inches

3 feet = 1 yard

To solve 5 feet + 12 inches = blank yard(s), convert 5 feet & 12 inches to yards. Since 5 feet would be complicated to convert, let's convert 12 inches to feet first.

12 inches = 1 feet

Instead of 12 inches, we can substitute it as 5 feet + 1 feet = blank yard(s). That would be 6 feet = ? yards. 3 feet = 1 yard, which tells us we must divide both sides by 3. Thus, 5 feet + 12 inches = 2 yards.

Blank inches = 1 foot + 1 yard

To find the # of inches in a yard, you must first know that 3 feet = 1 yard. If there are 12 inches in a foot, we must multiply 3 by 12, getting us 36. You add 12 inches (1 foot), getting us 48 inches in total. Thus 48 inches = 1 foot + 1 yard.

Blank feet = 3 feet + 24 inches

Since 3 feet is already feet, we do not need to convert it. If 12 inches is 1 foot, we must divide 24 inches by 12. So, there is 2 feet in 24 inches. 2 + 3 is 5. Thus, 5 feet = 3 feet +24 inches.

Answer:

  2500 ft²

Step-by-step explanation:

The missing area at lower right in the diagram has dimensions ...

  (4 -2 1/4) by (3 -1 3/4) = (1 3/4) by (1 1/4)

Then the area of that "missing" space is ...

  (1.75)(1.25) = 2.1875 . . . . square inches.

The area of the enclosing rectangle is ...

  (4 in)(3 in) = 12 square inches

Then the area in the diagram representing the store is ...

  12 in² -2.1875 in² = 9.8125 in²

__

Each square inch on the diagram represents an actual area of ...

  (1 in)×(1 in) ⇒ (16 ft)×(16 ft) = 256 ft²

Then the actual store area is ...

  9.8125(256 ft²) = 2512 ft²

Rounded to the nearest 50 ft², this is 2500 ft².

Answer:

re arranging the equation

y = -x-10

the slope is -1

and the intercept is -10

Final Answer:

In-depth explanation:

Hi! The question is asking us to find the slope & the y-intercept of the following line:

First, we will rearrange this equation and write it in slope-intercept form.

Subtract x from both sides:

\(\bf{y=-10-x}\)

You can also rearrange the terms, like this:

\(\bf{y=-x-10}\)

_____________________

Now, what is the slope and y-intercept of this line? To find the slope, we recall that the slope is the number before x. In this case it's 1.

As for the y-intercept, it's the constant term, or -10 in this case.

Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.

-----------------------

The radius is 1 & 7/16

Let's convert this to decimal form

1 & 7/16 = 1 + (7/16)

1 & 7/16 = 1 + 0.4375

1 & 7/16 = 1.4375

The radius is r = 1.4375 inches.

-----------------------

SA = Surface area the sphere

SA = 4*pi*r^2

SA = 4*pi*(1.4375)^2

SA = 25.9672267773281

SA = 25.97 square inches (choice E)

-----------------------

V = Volume of the sphere

V = (4/3)*pi*r^3

V = (4/3)*pi*(1.4375)^3

V = 12.4426294974698
