Answer: 1.Use of traditional tests may not evaluate how hard a student is willing to work to get a good evaluation

Step-by-step explanation:

Proponents of Traditional Tests argue that they are fairer because hard working students who may fail standadized tests may be able to pass them.

However, the text shows that that arguement has loopholes because a student could pass those Traditional testing methods by employing methods that are void of hard-work such as receiving help from other people or buying a customized essay over the internet.

Should this be the case then, Traditional tests may not be able to properly evaluate a student's hard work because one can not know if the submitted content was solely due to hard-work or if there was assistance from somewhere.

Answer:

3.Use of non-traditional tests to evaluate students is not necessarily fairer than using standardized tests to evaluate students.

Step-by-step explanation:

The Use of non-traditional tests to evaluate students is not necessarily fairer than using standardized tests to evaluate students because it is difficult to determine if a student received any help from others in putting together his or her portfolio, essay or project except if he is closely monitored by the teacher. Also a student may pay someone online to write a customized essay for him/her via the internet therefore it cannot be concluded whether it is due to the student's hard work or due to assistance the student received from others.

Answer:

[tex]\cos{\theta} = \frac{\sqrt{15}}{4}[/tex]

Step-by-step explanation:

For any angle [tex]\theta[/tex], we have that:

[tex](\sin{\theta})^{2} + (\cos{\theta})^{2} = 1[/tex]

Quadrant:

[tex]0 \leq \theta \leq \frac{\pi}{2}[/tex] means that [tex]\theta[/tex] is in the first quadrant. This means that both the sine and the cosine have positive values.

Find the cosine:

[tex](\sin{\theta})^{2} + (\cos{\theta})^{2} = 1[/tex]

[tex](\frac{1}{4})^{2} + (\cos{\theta})^{2} = 1[/tex]

[tex]\frac{1}{16} + (\cos{\theta})^{2} = 1[/tex]

[tex](\cos{\theta})^{2} = 1 - \frac{1}{16}[/tex]

[tex](\cos{\theta})^{2} = \frac{16-1}{16}[/tex]

[tex](\cos{\theta})^{2} = \frac{15}{16}[/tex]

[tex]\cos{\theta} = \pm \sqrt{\frac{15}{16}}[/tex]

Since the angle is in the first quadrant, the cosine is positive.

[tex]\cos{\theta} = \frac{\sqrt{15}}{4}[/tex]

Answer:

b.[tex]\frac{\sqrt{15} }{4}[/tex]

Step-by-step explanation:

Answer:

If it's a simple equation such as 2 (x + y), the next step after applying the distributive property is to do the multiplication and simplify the terms.

But in solving an equation such as

2(x + 3) = 3(x + 1)

After applying the distributive property, the next step is to separate the variables to one side, like collecting like terms and then solving the now simplified equation.

Step-by-step explanation:

For a normal equation, the distributive property, also called the distributive law of division and multiplication helps to use the variable outside the bracket to multiply the sum of terms in the bracket. For example.

2 (x + y)

The distributive property enables us to say

2×x + 2×y = 2x + 2y

So, the next step after applying the distributive property is to simplify the equation.

But in solving an equation such as

2(x + 3) = 3(x + 1)

Applying the distributive property

2x + 6 = 3x + 3

We then operate variables, collect like terms on one side

6 - 3 = 3x - 2x

3 = x

x = 3

The probability that you roll a 5 or 2 is [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

There are 6 total outcomes(all numbers from 1 to 6).

The desired are 2, that is, rolling 2 or rolling 5.

p = 2/6 = 1/3

The probability that you roll a 5 or 2 is [tex]\frac{1}{3}[/tex]

Answer:5/2

Step-by-step explanation:

The square root of 10 is a number with the following property: when you square it, you get 10.

So, if we have [tex]a<\sqrt{10}<b[/tex], where [tex]a[/tex] and [tex]b[/tex] are positive integers, if we square the whole inequality we have

[tex]a^2<10<b^2[/tex]

Let's analyse option A for example. Given everything we said so far, we would have

[tex]1<\sqrt{10}<2 \iff 1^2<10<2^2 \iff 1<10<4[/tex]

which is false.

Option B is again false, because we would have

[tex]2<\sqrt{10}<3 \iff 2^2<10<3^2 \iff 4<10<9[/tex]

which is again false. Keep trying with options C and D following those same steps, and see which one is correct

Answer:

9(5x - 3) option (c)

Step-by-step explanation:

The question isn't clear as well as incomplete without the options. Since there are no options let's determine the answer of the following mathematical expression:

45x - 27

a) 9(3x - 5)

b) 3(12x + 7)

c) 9(5x - 3)

d) 5(7x + 30)

To determine which option is equivalent to 45x - 27, we would check each option by expanding the bracket. Apply BODMAS (stands for Bracket, Of, Division, Multiplication, Addition and Subtraction) after the expansion. That is multiply before you add or subtract.

a) 9(3x - 5) = 9×3x - 5×9

= 27x - 45

b) 3(12x + 7) = 3×12x + 3×7

= 36x + 21

c) 9(5x - 3) = 9×5x - 9×3

= 45x - 27

d) 5(7x + 30) = 5×7x + 30×5

= 35x + 150

From the expansion, only option C is equal to the given expression: 45x - 27

Answer:

  c > -7/8

Step-by-step explanation:

Add 2 for an inequality that compares to zero:

  2x^2 -3x +(c+2) > 0

This will be true when the discriminant is negative. For the quadratic ...

  ax^2 +bx +c

the discriminant is ...

  b^ -4ac

We want this to be negative:

  (-3)^2 -4(2)(c+2) < 0

  9 -8(c +2) < 0

  9 -8c -16 < 0

  -7 < 8c

  -7/8 < c

The given inequality will be true for all values of c greater than -7/8.

Answer:

Step-by-step explanation:

In a standard normal probability distribution, the Z-value depends on the data set, the mean and the standard deviation, that means, it's a variable measure, it's not a constant, that's why the choice d is wrong.

On the other hand, the other choices are correct regarding standard normal probability distribution.

Therefore, the right answer is d.

Answer:

amount of the drug becomes approximately equal to 0.2 milligrams after 13.04 hours

Step-by-step explanation:

Given: The function [tex]f(t)=10e^{-0.3 t}[/tex] represents number of milligrams of a drug in a person’s body after t hours

To find: time after which amount of the drug becomes approximately 0.2 milligrams

Solution:

[tex]f(t)=10e^{-0.3 t}\\0.2=10e^{-0.3 t}\\\frac{0.2}{10}=e^{-0.3 t}\\\frac{2}{100}=e^{-0.3 t}\\\frac{1}{50}=e^{-0.3 t}\\[/tex]

As [tex]e^x=y\Rightarrow x=\ln y[/tex] ,

[tex]50=e^{0.3 t}\\0.3t=\ln 50\\t=\frac{\ln 50}{0.3}=13.04\,\,hours[/tex]

So, amount of the drug becomes approximately equal to 0.2 milligrams after 13.04 hours

Answer: 14.2638366937

Step-by-step explanation:

A geometric sequence is a sequence in which each term is multiplied by a number, called the common ratio, to get the next term.

So, if the first term of the geometric sequence is 10 and the common ratio is 0.3, the sequence would be 10, 0.3(10), 0.3 x 0.3 x 10... and so forth. This becomes:

10, 3, 0.9, 0.27, 0.081, 0.00243, 0.00729, 0.002187, 0.0006561, 0.00019683, 0.000059049, 0.0000177147...

You add these first 12 terms to get 14.2638366937.

Answer: 31°

Step-by-step explanation:

We know that a right triangle is equal to 180°. Since this is a right triangle, we know that one angle is 90°. Since we are given out other angle, it is very easy to find the missing angle.

180°=59°+90°+x

180°=149°+x

x=31°

Answer: The top right and bottom right polygons are parallelograms and not squares.

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of parallel sides opposing each other.

A square is a quadrilateral with two pairs of parallel sides opposing each other; however, all four sides must be equal and all angles must equal 90 degrees.

Any quadrilateral that is a parallelogram and not a square has angle measures that are not 90 degrees (or have unequal sides).

Only the top right and bottom right images are parallelograms and not squares.

The shapes that are parallelogram but not a square is the rectangle and the parallelogram. The rhombus is a square because the angles are 90°.

A quadrilateral is a polygon with four sides and four angles. A parallelogram is a quadrilateral with parallel and equal opposite sides.
