Answer:

B The measurement found using Ruler 2 is more accurate and more precise.

Step-by-step explanation:

We have to understand the concept here for accuracy and precision.

Accuracy is against some standard. So it is the measured value which is closely against a standard. Accuracy is less if the measured value is deviated from the standard.

Precision is about how closely individually measured values agree with each other. Precision doesn't concern with the standard value.

Now, third concept is significant numbers. It is up to how much decimal numbers an instrument can produce a result.

In ruler 2, you can see that there are more divisions for a whole inch. This means that the ruler 2 can measure more nearly to the standard value, as well as, for repeated measurements, it can give more precised figures due to the ability to read up to more decimal numbers after the decimal point.

Answer: Option C  

[tex]r ^ 2 = 0.684[/tex]

Step-by-step explanation:

The correlation coefficient r is a measure of how strong the relationship between two variables x and y is.

 If the value of r is positive then the correlation is positive and that implies that the variable x grows together with the variable y.

If the value of r is negative that means that the correlation is negative and that implies that when the variable x grows then the variable y decreases.

Then for a  relationship, the coefficient of determination [tex]r ^ 2[/tex] is a measure of how well the model fit the data or how accurate the model is. While r is closer to 1, better is the precision of the model.

The coefficient of determination [tex]r ^ 2[/tex] for a linear relationship is calculated as the square of the correlation coefficient.

In this problem we have that the correlation coefficient r is

[tex]r = 0.827[/tex]

then the coefficient of determination is:

[tex]r ^ 2 = 0.827 ^ 2[/tex]

[tex]r ^ 2 = 0.684[/tex]

The capacity of the remaining bottles = 4 pints.

Step-by-step explanation:

6*3 + 6*b = 42

6b = 42 - 18

6b = 24

b = 4.

The required quantity of the remaining 6 bottles is 4 pints.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Ben fills 42 pints of juice in 12 bottles. Six bottles have a capacity of 3 pints each.

Let b represent the capacity, in pints, of each of the remaining 6 bottles.,
Now,
42 = 3 × 6 + b × 6
42 = 18 + 6b
6b = 42 - 18
b = 24/6
b = 4

Thus, the required quantity of the remaining 6 bottles is 4 pints.

12) Lowest Common Denominator of

[tex]\frac{p+3}{p^2+7p+10} \,\, and \,\, \frac{p+5}{p^2+5p+6}[/tex]

We should find the factors of denominators and then find the LCM of the denominators.Finding LCD is same as finding LCM.

Factors of p^2+7p+10 = p^2 +2p +5p+10 = p(p+2)+5(p+2) = (p+5)(p+2)

Factors of p^2+5p+6 = p^2+2p+3p+6 = p(p+2)+3(p+2) = (p+3) (p+2)

Now, rewriting the above equation with factors and finding the LCM

[tex]\frac{p+3}{(p+5)(p+2)} \,\, and \,\, \frac{p+5}{(p+3)(p+2)}\\[/tex]

LCM of (p+5)(p+2) and (p+3)(p+2) = (p+5)(p+3)(p+2)

The LCD is (p+5)(p+3)(p+2).

Answer:

Choice A is correct

Step-by-step explanation:

We have been given the expression;

[tex]x^{\frac{9}{7} }[/tex]

In order to re-write this expression, we shall use some laws of exponents;

[tex]a^{\frac{b}{c} }=(a^{b})^{\frac{1}{c} }[/tex]

Using this law, the expression can be written as;

[tex](x^{9})^{\frac{1}{7}}[/tex]

The next thing we need to remember is that;

[tex]a^{\frac{1}{n} }=\sqrt[n]{a}[/tex]

Therefore, the expression becomes;

[tex]\sqrt[7]{x^{9} }[/tex]

Next,

[tex]x^{9}=x^{7}*x^{2}[/tex]

This implies that;

[tex]\sqrt[7]{x^{9} }=\sqrt[7]{x^{7}*x^{2}}\\=\sqrt[7]{x^{7} }*\sqrt[7]{x^{2} } \\=x\sqrt[7]{x^{2} }[/tex]

ANSWER

A.

[tex]x \sqrt[7]{{x}^{2} } .[/tex]

EXPLANATION

The given expression is

[tex] {x}^{ \frac{9}{7} } [/tex]

We want to rewrite the given expression in radical form:

Recall that:

[tex] {a}^{ \frac{m}{n} } = \sqrt[n]{ {a}^{m} } [/tex]

This implies that:

[tex] {x}^{ \frac{9}{7} } = \sqrt[7]{ {x}^{9} } [/tex]

[tex]{x}^{ \frac{9}{7} } = \sqrt[7]{ {x}^{7} \times {x}^{2} } [/tex]

Split the radicals.

[tex]{x}^{ \frac{9}{7} } = \sqrt[7]{ {x}^{7} } \times \sqrt[7]{{x}^{2} } [/tex]

This finally simplifies to:

[tex]{x}^{ \frac{9}{7} }=x \sqrt[7]{{x}^{2} } [/tex]

Step-by-step explanation:

As per the given quadratic function, the value of the vertex of the graph is written as (5, 1)

A quadratic function is a polynomial function of degree 2, typically written in the form f(x) = ax² + bx + c, where a, b, and c are constants, and a ≠ 0. However, the given quadratic function is already expressed in the desired form, f(x) = a(x - h)² + k, which is known as vertex form. In this form, (h, k) represents the coordinates of the vertex of the parabola.

Now, let's rewrite the given quadratic function f(x) = 2x² - 20x + 51 in the vertex form. To achieve this, we'll complete the square:

Step 1: Factor out the leading coefficient 'a' from the x² and x terms. f(x) = 2(x² - 10x) + 51

Step 2: Complete the square inside the parentheses by adding and subtracting the square of half of the coefficient of the x-term (in this case, -10/2 = -5, and (-5)² = 25). f(x) = 2(x² - 10x + 25 - 25) + 51

Step 3: Group the perfect square trinomial and the constant term inside the parentheses. f(x) = 2((x - 5)² - 25) + 51

Step 4: Distribute the leading coefficient 'a' back into the parentheses. f(x) = 2(x - 5)² - 50 + 51

Step 5: Combine the constants. f(x) = 2(x - 5)² + 1

Now, the quadratic function is in the form f(x) = a(x - h)² + k, where a = 2, h = 5, and k = 1.

Therefore, the vertex of the parabola is (h, k) = (5, 1).

The figure is rotated 90 degrees clockwise then translated down 3 units and left 2 units.

The blue triangle becomes the purple triangle by rotating 90° clockwise then translated down 3 units and left 2 units, so, option D is correct.

A shape is translated when it is moved to the left, right, up, or down without turning. Congruence is demonstrated by the fact that the translated shapes (or the image) seem to be the same size as the original ones. Simply said, they have changed their path or directions.

Given:

The blue triangle becomes the purple triangle in the graph,

All rotations are about the origin,

The Clockwise motion, also known as CW, moves from top to bottom, then down and left, and then back to top in the same manner as a clock's hands.

Answer: 15 cm

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

[tex]A=l*w[/tex]

Where "l" is the lenght and "w" is the width.

You know that the area of this rectangle is 75 square centimeters and the width is 5 centimeters. Then, you can substitute these values into the formula [tex]A=l*w[/tex] and solve for the lenght. Then you get:

[tex]75cm^2=l(5cm)\\\\\frac{75cm^2}{5cm}=l\\\\l=15cm[/tex]

Therefore, the lenght of the rectangle is 15 centimeters.

Answer:

15 centimeters.

Step-by-step explanation:

To find the area of a rectangle, you have to multiply the length by the width.

In this case, the width is 5 centimeters.

So, so find the area, you would have to multiply 5 by the length. Let's call the length "x".

The equation to solve this problem would be:

5x - 75

Now we can solve the equation...

Divide both sides by 5...

5x / 5 = 75 / 5

x = 15

Since x is equal to 15, that means that the length is 15, because we said that the length is equal to x.

Length = x = 15
