find the value of x that will make A || B

Answer:

5 boxes

Step-by-step explanation:

Given:

Total crayons : 98

Capacity of each box : 24

Number of boxes of 24 crayons needed to hold 98 crayons,

= 98 ÷ 24

= 4.08 boxes.

However since we cannot have 0.08 of a box, we must round this up to the next larger whole number of boxes.

4.08 rounded up to next whole number = 5

Hence he will need 5 boxes to hold all 98 crayons

The solutions to the equation [tex]\( 2x^2 + 8 = 0 \)[/tex] are complex numbers [tex]\( x = 2i \) and \( x = -2i \), where \( i \)[/tex] is the imaginary unit.

The statement that the graph of [tex]\( 2x^2 + 8 = 0 \)[/tex] does not cross the x-axis is correct, as the graph of this equation represents a parabola that opens upwards and is centered above the x-axis, meaning it has no real roots.

To find the solutions for the equation [tex]\( 2x^2 + 8 = 0 \)[/tex], we can start by isolating [tex]\( x^2 \):[/tex]

[tex]\[ 2x^2 = -8 \][/tex]

Dividing both sides by 2:

[tex]\[ x^2 = -4 \][/tex]

Now, to solve for ( x ), we take the square root of both sides:

[tex]\[ x = \pm \sqrt{-4} \][/tex]

[tex]\[ x = \pm 2i \][/tex]

So, the solutions to the equation [tex]\( 2x^2 + 8 = 0 \)[/tex] are complex numbers [tex]\( x = 2i \) and \( x = -2i \), where \( i \)[/tex] is the imaginary unit.

These are the roots of the equation, even though they do not lie on the real number line.

Hence, while there are no real solutions, there are indeed complex solutions for the given function.

Answer:

18/20 or 9/10

Step-by-step explanation:

The list shows the amount of hours each student USED the computer.

Wherever we see a "0", that means he/she DID NOT USE computer.

There are 2 "zeroes", so 2 didnt use out of 20, so number of student who DID USE is 20 - 2 = 18

To find ratio of total number of students who used to the total number surveyed, it is going to be:

18/20 or 9/10

Answer:

Ratio would be 9 : 10

Step-by-step explanation:

Liliana surveyed 20 students that how many hours they spend on their computers each week.

The results are as follows

8, 15, 0, 11, 12, 13, 16, 13, 0, 4, 17, 14, 30, 13, 5, 12, 1, 13, 12, 21

In the above results 2 students did not use computers out of 20 students.

Therefore, The total number of students who used their computers = 20 - 2 = 18

So the ratio would be 18 : 20 or 9 : 10

Answer:

3.75.

Step-by-step explanation:

Substitute x = 1/2 into x^2 + 3.5:

(1/2)^2 + 3.5

= 1/4 + 3.5

= 3.75.

Answer:

Step-by-step explanation:

[tex]\text{Put the value of}\ x=\dfrac{1}{2}=0.5\ \text{to the expression}\ x^2+3.5:\\\\0.5^2+3.5=0.25+3.5=3.75[/tex]

The complete table of values for the equation y = x/4 is

x   4   2  9

y  1   1/2  9/4

From the question, we have the following parameters that can be used in our computation:

y = x/4

The missing y values are at x = 4, 2 and x = 9

Substitute the known values in the above equation, so, we have the following representation

y = 1/4 * 4 = 1

y = 1/4 * 2 = 1/2

y = 1/4 * 9 = 9/4

So, the missing values are 1, 1/2 and 9/4

Final answer:

The rule 'y = X/4' describes division of X by 4 to find Y. The student completes the table by dividing each X value by 4 to find the corresponding Y values, providing an organized data set.

Explanation:

The student is asking about the operation indicated by the rule y = X/4, which involves division. The fraction bar signifies division. Given this rule, we can complete the table for y when x-values are provided.

For x = 4: y = 4/4 = 1

For x = 2: y = 2/4 = 0.5

For x = 9: y = 9/4 = 2.25

To organize the data in the table, you simply divide the x-value by 4 to find the corresponding y-value.

Final answer:

Three equivalent fractions for 60.1% with different denominators are found by converting the percent to a decimal and then to the requested fractions. The fractions are 601/1,000 (simplest form), 60.1/100 simplifies to 601/1,000, and 6.01/10 simplifies to 601/1,000.

Explanation:

To write three equivalent fractions for 60.1% with denominators of 1,000, 100, and 10, we first convert the percent to a decimal by dividing by 100. So, 60.1% becomes 0.601. This decimal can then be written as a fraction with the various denominators.

With a denominator of 1,000: 0.601 × 1,000/1,000 = 601/1,000

With a denominator of 100: 0.601 × 100/100 = 60.1/100 which simplifies to 601/1,000

With a denominator of 10: 0.601 × 10/10 = 6.01/10 which simplifies to 601/1,000

Note that 601/1,000 is the simplest form for the fraction equivalent of 60.1%. When we adjust for the different denominators, we always arrive back at the equivalent fraction of 601/1,000 because it is the simplest form.

Answer:

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Actually 1 and x both are polynomials. Therefore 1/x is already a quotient of polynomials.

Two polynomial expressions whose quotient, when simplified, is 1/x

x+1/x^2+x

Take the common of the denominator

x+1/x(x+1)

x+1 will be cancelled out by x+1

1/x

1/x is not a polynomial, so polynomials are not closed under division.

Polynomials are closed under addition, subtraction and multiplication. Addition and multiplication are associative and commutative.

There is an additive identity which is 0.

There is a multiplicative identity which is 1....

Polynomial expressions involve variables, coefficients, and exponents, combined by addition, subtraction, and multiplication. They are not closed under division, as shown by the quotient 1/x, which is not a polynomial. However, polynomials are closed under addition, subtraction, and multiplication.

A polynomial expression is a mathematical expression that can involve variables, coefficients, and exponents, that are combined using addition, subtraction, and multiplication operations. For your question, we can consider two polynomial expressions: x and 1. The quotient of these two expressions is 1/x.

However, 1/x is not a polynomial expression, because it involves division by a variable. This shows that polynomial expressions are not closed under division.

In contrast, polynomials are closed under the operations of addition, subtraction, and multiplication. For example, if we add, subtract or multiply any two polynomials we will always get another polynomial.

These operations do not generate any new type of expressions outside the realm of polynomials, unlike division, which can produce non-polynomial results, such as rational expressions.

Answer:

68%

Step-by-step explanation:

Probability of occurrence of Event v = P(v) = 28% = 0.28

Probability of occurrence of both Events v and Event w together = P(v and w) = 19% = 0.19

We have to find what is the probability  that event w occurs with event v given that event v  occurs on a Tuesday. This is a conditional probability. In other words we have to find what is the probability of event w given that event v occurs of Tuesday. i.e we have to find P(w|v)

The formula to calculate this conditional probability is:

[tex]P(w|v) = \frac{P(v \cap w)}{P(v)}[/tex]

Using the given values, we get:

[tex]P(w|v) = \frac{0.19}{0.28}\\\\ P(w|v) = 0.68\\\\ P(w|v) = 68\%[/tex]

Therefore, the probability that even w will occur with event v given that event v occurs on Tuesday is 68%
