Laura is thinking of a number such that the sum of the number and five times two more than the number is 26 more than four times the number. Determine the number Laura is thinking of.

1 trampoline= 98.50

y trampolines= 689.50

What I did was i got the number (689.50) and divided it by the other number (98.50)

\(689.50 / 98.50 = 7\)

And to check if its correct, I multiplied 98.50 with 7, which did come to 689.50.

7 trampolines= 689.50

thank you :D

Answer:

the question "What is the answer to this question?" is a paradoxical question that doesn't have a clear or meaningful answer.

Let the amount of the 30% solution be x gallons.

Then the amount of the 10% solution is (100 - x) gallons.

The amount of juice in the 30% solution is 0.3x gallons.

The amount of juice in the 10% solution is 0.1(100 - x) gallons.

When the two solutions are mixed, we get 100 gallons of a 12% juice solution, which means:

0.3x + 0.1(100 - x) = 0.12(100)

Simplifying this equation, we get:

0.3x + 10 - 0.1x = 12

0.2x = 2

x = 10

Therefore, 10 gallons of the 30% solution was used.

Step-by-step explanation:

Subtract

8  1/6 -2 and 7 over 82=127 over 2

Convert mixed number to improper fraction

8 1/6= 8x6/6+ 1/6=16+7/8=23/8

Margin of error for the 95% confidence interval used to estimate the population proportion is 0.0187

It is given that out of 2300 tv viewers, 690 said they watch network news program.

Sample n=2300

Number that watch network program (x)=690

We now find the margin error:

For 95% confidence interval, z-value is 1.96 from Chi-square distribution

We now get the point estimate, p:

p=x/n, where x=690, and n=2300

 =690/2300

 =0.3

Margin of Error=\(z*\sqrt{\frac{p*(1-p)}{n} }\)

                        \(=1.96*\sqrt{\frac{0.3*(1-0.3)}{2300} }\)

                        =0.0187

Hence, the margin error is 0.0187

During most of their eighth year, children have 24 teeth in their mouth, which include both primary and secondary teeth.

The primary teeth, also known as baby teeth, start erupting around six months of age and typically finish erupting by the age of two to three years. There are a total of 20 primary teeth, consisting of 8 incisors, 4 canines, and 8 molars.

As the child grows, the primary teeth start to shed, making way for the permanent teeth, also known as secondary teeth. The permanent teeth begin to erupt around the age of six, starting with the first molars. By the eighth year, most children have a mix of primary and secondary teeth.

At this stage, they would typically have 8 incisors, 4 canines, and 8 premolars, totaling 24 teeth in their mouth. The remaining permanent teeth, including the second molars and third molars (wisdom teeth), may continue to erupt later in the child's development.

Answer:

28 girls.

Step-by-step explanation:

b - number of boys

g - number of girls

b = 2*g

b + g = 84

2*g + g = 84

3*g = 84

g = 84/3 = 28

And just in case:

b = 2*g = 2*28 = 56

b + g = 28 + 56 = 84; the answer checks out ;)

Answer:

28

Step-by-step explanation:

Let the number of girls be x .

number of boys = 2x

Number of students in class =84

A/q,

2x +x = 84

3x =84

x= 84/3

x= 28

So number of girls in class is 28

The numerical measure of linear association is b. correlation coefficient.

The correlation coefficient is a statistical measure that represents the degree of linear relationship between two variables. It takes values between -1 and 1, where -1 represents a perfect negative linear correlation, 0 represents no linear correlation, and 1 represents a perfect positive linear correlation.

A positive correlation means that when one variable increases, the other variable also tends to increase, while a negative correlation means that when one variable increases, the other variable tends to decrease.

The correlation coefficient is calculated using the formula:

\(r = (nΣxy - ΣxΣy) / sqrt[(nΣx^2 - (Σx)^2)(nΣy^2 - (Σy)^2)]\)

where r is the correlation coefficient, n is the sample size, Σxy is the sum of the products of the corresponding values of x and y, Σx and Σy are the sums of x and y respectively, and Σx^2 and Σy^2 are the sums of the squares of x and y respectively.

In summary, the correlation coefficient is a measure of the strength and direction of the linear association between two variables.

Answer: 4.5 pounds.

Step-by-step explanation:

Given : Weight of original pipe =45 pounds

Weight of first piece = 18 pounds

Then, Weight of  other piece = 45- 18 =  27 pounds

Length of first piece = 3 feet

Let x be the length of other piece.

As length is directly proportional to weight.

Then, \(\dfrac{x}{27}=\dfrac{3}{18}\)

\(\Rightarrow\ \dfrac{x}{27}=\dfrac{1}{6}\\\\\Rightarrow\ x=\dfrac{1}{6}\times27 =4.5\)

Hence, the he length of the other piece = 4.5 pounds.

Step-by-step explanation:

Answer:

discounted price = original price ( 1 - discount rate)

Step-by-step explanation:

The value of y' at the point (2, -1) is 5.

To evaluate y' at the given point, we need to find the derivative of the given equation with respect to x and then substitute x = 2 and y = -1.

The given equation is: ey + 12 - e^(-1) = 2x^2 + 4y^2.

First, let's differentiate both sides of the equation with respect to x:

d/dx (ey + 12 - e^(-1)) = d/dx (2x^2 + 4y^2)

Using the chain rule, the derivative of ey with respect to x is ey * (dy/dx). Differentiating the remaining terms, we have:

ey * (dy/dx) + 0 - 0 = 4x + 8y * (dy/dx)

Now, we can substitute x = 2 and y = -1 into the equation:

ey * (dy/dx) + 0 - 0 = 4(2) + 8(-1) * (dy/dx)

ey * (dy/dx) = 8 - 8 * (dy/dx)

Simplifying, we get:

(1 + 8) * (dy/dx) = 8

9 * (dy/dx) = 8

(dy/dx) = 8/9

(dy/dx) = 8/9

Therefore, y' at the point (2, -1) is 8/9, or approximately 0.889.

Please note that in the initial response, I made an error in the calculation. The correct value of y' at the point (2, -1) is 8/9, not 5. I apologize for the confusion.

Mathematics is a fundamental subject in education that is essential in the development of an individual’s critical thinking and problem-solving skills. It is one of the primary subjects that are taught in elementary schools and must be taught appropriately for children to understand and gain the required skills. One true statement about mathematics teaching in elementary schools is that it should be student-centered.

Teachers should focus on the child's understanding, individual learning abilities and styles, and progress.The learning experience should not be centered on the teacher but on the students. Teachers should also make the subject engaging and interactive to enable students to grasp the content easily and maintain their interest in the subject. Besides, teachers should develop a personalized learning approach that allows students to learn and understand the subject at their own pace while creating opportunities for individual and group learning. Through such learning approaches, students can develop the required mathematical concepts and competencies such as critical thinking, problem-solving, and decision-making skills that will be beneficial in their future endeavors.
