Answer:

[tex]\boxed{\bf u=7}[/tex]

Step-by-step explanation:

[tex]\sf 2u+2.17=16.17[/tex]

Subtract 2.17 from both sides:-

[tex]\sf u+2.17-2.17=16.17-2.17[/tex]

[tex]\sf 2u=14[/tex]

Divide both sides by 2:-

Sarah's error in the expression 3 so the correct answer is option D

Complete Question: Sarah used properties of operations to write the following three equivalent expressions to.

A. There are no errors. All of the expressions are equivalent.

B. Expression 1. Sarah can’t apply the Distributive Property if there are three addends.

C. Expression 2. Sarah can’t combine -4 and -6. She must combine -4 with 8.

D. Expression 3. Sarah applied the Distributive Property but incorrectly multiplied 1/2 (-6).

Expressions 1, and 2 are equivalent because they are using the distributive property to expand the term within the brackets before applying the 1/2 coefficient.

Expression 3 is not equivalent because it does not use the distributive property and does not have the same terms as the other expressions.

Sarah's error in expression 3 is that she did not use the distributive property and the terms inside the brackets are not the same as the other expressions, hence the results are different.

Therefore, Sarah's error in the expression 3 so the correct answer is option D

Answer:

Dilation of 3

Step-by-step explanation:

Note [tex]DE=2[/tex] and [tex]D'E'=6[/tex].

The scale factor is defined as the ratio of the length of the side of the image to the length of the corresponding side of the preimage.

So, the scale factor is [tex]\frac{6}{2}=3[/tex].

The dilation shown in the image is a dilation with a scale factor of 3

The transformation rule for dilation is as follows

(x, y) for a scale factor of r → (3x, 3y)

Dilation is a method of transformation that magnify or shrink the preimage depending on the scale factor

Generally,  transformation rule for dilation is as follows

(x, y) for a scale factor of r → (rx, ry)

Examining the figure, Using side DE as reference we can see that DE is 1 unit

After dilation side D' E' transformed to 3 units, showing an increment of 3.

The dilation is an enlargement and the scale factor is 3

The solution of the equation is x = [tex]\frac{\sqrt{3} }{2}[/tex] and - [tex]\frac{\sqrt{3} }{2}[/tex].

Now, According to the question:

What is Quadratic Equation?

The polynomial equation whose highest degree is two is called a quadratic equation or sometimes just quadratics. It is expressed in the form of:

ax² + bx + c = 0

where x is the unknown variable and a, b and c are the constant terms.

The given equation is :

40x² = 30

40x² - 30 =0

Common factor:

10(4x²- 3) = 0

Divide both sides by the same factor

10(4x²- 3) = 0

4x²- 3 = 0

Use the quadratic formula:

x = -b±[tex]\sqrt{b^2-4ac}[/tex]/ 2a

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula:

4x²- 3 = 0

a = 4

b = 0

c = -3

x =  -0±[tex]\sqrt{0^2-4(4)(-3)}[/tex]/ 2(4)

By simplify:

x = ±[tex]\frac{4\sqrt{3} }{8}[/tex]

To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

x = [tex]\frac{4\sqrt{3} }{8}[/tex]

x = -[tex]\frac{4\sqrt{3} }{8}[/tex]

Rearrange and isolate the variable to find each solution

x = [tex]\frac{\sqrt{3} }{2}[/tex] and - [tex]\frac{\sqrt{3} }{2}[/tex]

Hence, The solution of the equation is x = [tex]\frac{\sqrt{3} }{2}[/tex] and - [tex]\frac{\sqrt{3} }{2}[/tex].

Step-by-step explanation:

The endpoint of a titration can be found by various methods like visual indicators, conductometric titration, volumetric titration, etc.

The endpoint of a titration is the point at which the reaction between the acid and base is complete. In other words, it is the point at which the acid and base have been neutralized, and the solution reaches a neutral pH of 7.0. There are several ways to determine the endpoint of a titration, including:

To find the endpoint, it is important to use a suitable indicator that changes color in the range of pH close to the endpoint of the titration. It's also important to use a burette to measure the volume of the titrant added and use it to plot the titration curve.

The longest side in a right triangle is the hypotenuse, which is the side opposite the right angle.

In ∆ XYZ, if X is the right angle, then the hypotenuse would be the side connecting points Y and Z. This is because in a right triangle, the hypotenuse is always the side opposite the right angle and is also the longest side in the triangle. This can be proven using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

A linear model can be represented by the equation y = mx + b, where y is the dependent variable (megawatt hours generated by hydropower), x is the independent variable (years since 2007), m is the slope of the line, and b is the y-intercept.

To find the slope (m) and y-intercept (b) for this problem, we can use the two points given: (2007, 248) and (2012, 277).

m = (277 - 248) / (2012 - 2007) = 29 / 5 = 5.8

b = 248 - (5.8)(2007) = 248 - 11456 = -11208

So the linear model representing the number of megawatt hours generated by hydropower as a function of the number of years since 2007 is:

y = 5.8x - 11208

where x is the number of years since 2007.

In mathematics, a percentage (from Latin: per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%",although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number (pure number); it has no unit of measurement.

The term "percent" is derived from the Latin per centum, meaning "hundred" or "by the hundred". The sign for "percent" evolved by gradual contraction of the Italian term per cento, meaning "for a hundred". The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to two circles separated by a horizontal line, from which the modern "%" symbol is derived.

The interquartile range (IQR) of this dataset is 8.25, it means that half of the observations fall between 53 and 61.25, while half of the observations fall outside of that range.

IQR stands for Interquartile Range, which is a measure of the variability of a dataset. It is defined as the difference between the third quartile (Q3) and the first quartile (Q1). To calculate the IQR, you first need to order the data set and find the median (middle value) of the dataset, and the Q1 and Q3.

Here is the dataset you provided, in order:

53 53 53 54 55 56 59 60 61 62 63 88

The median of the dataset is: (56+59)/2 = 57.5

Q1 is the median of the lower half of the dataset: (53+53+54)/3 = 53

Q3 is the median of the upper half of the dataset: (60+61+62+63)/4 = 61.25

Now you can calculate the IQR:

IQR = Q3 - Q1 = 61.25 - 53 = 8.25

So the interquartile range of this dataset is 8.25, it means that half of the observations fall between 53 and 61.25, while half of the observations fall outside of that range.
