Answer:

C. There is not enough information to make any conclusions regarding the new review booklet.

Step-by-step explanation:

Given that A statistics teacher conducted an experiment to test whether the use of a new review booklet will improve her students' semester grades.

also given that The teacher randomly selected 20 students from her class and assigned the new review booklet to 10 of the students. The remaining 10 students did not use any review material.

The semester grades did not differ for both groups.

But we cannot conclude the booklet has no effect because,

i) The sample size is very small, only 10.  Hence not reliable

ii) We do not know the previous performance of both the groups. To ensure improvement the grades the students got in the previous exam also should be considered.

Answer:

x = -2

Step-by-step explanation:

If you factor out 1/9 you get rid of the fractions and that makes the equation a whole lot easier.

[tex](5x+10)^2 - x(25x+27) + 46 = 0[/tex]

Next, eliminate the brackets:

[tex]25x^2 +100x + 100 - 25x^2 - 27x + 46 = 0[/tex]

Combine the terms:

[tex]x = \frac{- 146}{73} = -2[/tex]

Answer:

x = - 2

Step-by-step explanation:

The 9 does absolutely nothing. Multiply the whole equation by. 9. Remember that each term must show the 9 is missing

(5x + 10)^2 - x(25x + 27)  + 46 = 0

Next expand the first and second binomial so that the brackets can be removed.

(25x^2 + 100x + 100) - (25x^2 + 27x) + 46 = 0  

Now remove the brackets

25x^2 + 100x + 100 - 25x^2 - 27x + 46 = 0

Collect the like terms

25x^2 - 25x^2 + 100x - 27x + 100 +46 = 0

73x + 146 = 0                

Subtract 146 from both sides

73x = - 146

Divide by 73

x = - 146/73

x = - 2     <<<<                Answer

Answer:

π4;3π4

Step-by-step explanation: Trig table gives:

sinx=√22 --> arc x=π4

Unit circle gives another arc x that has the same sin value:

x=π−π4=3π4

The exact value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is not defined within the real numbers because the sine function has a range of [tex]\([-1, 1]\)[/tex], and the argument [tex]\(-2\sqrt{2}\)[/tex] lies outside this interval. The arcsine function, [tex]\(\arcsin(x)\)[/tex], is only defined for [tex]\(x\)[/tex] in the interval [tex]\([-1, 1]\)[/tex] .

To illustrate, the sine function reaches its maximum value of [tex]\(1\)[/tex] at [tex]\(\frac{\pi}{2}\)[/tex] and its minimum value of [tex]\(-1\)[/tex] at [tex]\(-\frac{\pi}{2}\)[/tex]. Any value outside the interval [tex]\([-1, 1]\)[/tex] is not within the domain of the inverse sine function. Therefore,[tex]\(\arcsin(-2\sqrt{2})\) does not have a real value.[/tex]

However, if we were to consider complex numbers, we could use Euler's formula and the definition of the complex logarithm to find a complex value for [tex]\(\arcsin(-2\sqrt{2})\)[/tex]. The general formula for the arcsine of a complex number [tex]\(z\)[/tex] is given by:

[tex]\[ \arcsin(z) = -i \ln\left(iz + \sqrt{1 - z^2}\right) \][/tex]

For [tex]\(z = -2\sqrt{2}\)[/tex], we would have:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + \sqrt{1 - (-2\sqrt{2})^2}\right) \][/tex]

Simplifying the expression under the square root:

[tex]\[ \sqrt{1 - (-2\sqrt{2})^2} = \sqrt{1 - 8} = \sqrt{-7} \][/tex]

Since [tex]\(\sqrt{-7} = i\sqrt{7}\)[/tex], we can continue the calculation:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + i\sqrt{7}\right) \][/tex]

This expression involves the complex logarithm, which is multi-valued due to the periodicity of the complex exponential function. Therefore, the value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] in the complex plane is not unique and requires careful handling of the branch cuts of the logarithm function. However, as stated earlier, within the realm of real numbers, [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is undefined.

Answer:

[tex]log_{e}[/tex] 35 = a

Step-by-step explanation:

using the law of logarithms

• [tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

[tex]e^{a}[/tex] = 35 ⇒ [tex]log_{e}[/tex] 35 = a

For this case we must divide the following expression:

[tex]\frac {413} {129}[/tex]

The expression can not be simplified. When dividing we have that its decimal form is given by:

3,201550

If we convert to a mixed number we have:

[tex]3 \frac {26} {129}[/tex]

Verifying:

[tex]3 \frac {26} {129} = \frac {129 * 3 + 26} {129} = \frac {413} {129}[/tex]

Answer:

[tex]3 \frac {26} {129}[/tex]

Answer:

1% of 4000 + 4% of B = 2% of (4000 + B)

40 + 0.04*B = 0.02( 4000 + B)

40 + 0.04* B = 80 + 0.02*B

40 + 0.04*B - 80 - 0.02B = 0

0.02*B - 40 = 0

0.02*B = 40

2B = 4000

B = 2000

Step-by-step explanation:

Plant B produced 1000 panels.

The total number of defective panels from Plant A is 7% of 6000,

= (7/100) x 6000

= 420 panels.

and, total number of defective panels from Plant B is 2% of x,

= (2/100) x

= (1/50) x.

The overall number of defective panels from both plants is 4% of the total number of panels

= (4/100)(6000 + x)

= (1/25) (6000 + x).

Now, set up the equation:

420 + (1/50)  x = (1/25) (6000 + x)

To solve for x, we can multiply both sides of the equation by 50 * 25 to eliminate the fractions:

50 . 25 . 420 + 50 x = 25 (6000 + x)

125000 + 50x = 150000 + 25x

50x - 25x = 150000 - 125000

25x = 25000

x = 25000 / 25

x = 1000

Therefore, Plant B produced 1000 panels.

Step-by-step explanation:

355/17=20.88235294 then 284/20.88235294=13.6

For this case, you want to know how many gallons of gasoline Nicole needs to drive 284 miles, knowing that with 17 she drove 355 miles. For this, we make a rule of three:

[tex]355 \ miles -----------> 17 \ gallons\\284 \ miles -----------> x[/tex]

Where "x" represents the number of gallons consumed in 284 miles.

[tex]x = \frac {284 * 17} {355}\\x = 13.6 \ gallons[/tex]

So, Nicole will need 13.6 gallons of gas to drive 284 miles

When subtracting mixed numbers, rename the mixed number if the subtrahend is larger than the minuend by converting them into improper fractions and then subtracting the numerator while keeping the denominator the same.

When subtracting mixed numbers, you may need to rename the mixed number if the subtrahend is larger than the minuend.

This means that the whole number part of the subtrahend is greater than the whole number part of the minuend, or the fractions have different denominators.

To rename the mixed number, you convert it into an improper fraction.

Once both mixed numbers are in the same form, you can subtract them by subtracting the numerator and keeping the denominator the same. Finally, simplify the answer if needed.

"The graphs of [tex]\( y = x^2 \)[/tex] and [tex]\( y = 25 \)[/tex] intersect at the points where the value of [tex]\( x^2 \)[/tex] is equal to 25. To find these points, we set the equations equal to each other and solve for x :

[tex]\[ x^2 = 25 \][/tex]

Taking the square root of both sides gives us two solutions:

[tex]\[ x = \pm 5 \][/tex]

Therefore, the graphs intersect at [tex]\( (-5, 25) \) and \( (5, 25) \)[/tex].

Similarly, the graphs of [tex]\( y = x^2 \)[/tex] and [tex]\( y = 121 \)[/tex] intersect at the points where the value of [tex]\( x^2 \)[/tex] is equal to 121. We set the equations equal to each other and solve for [tex]\( x \)[/tex]:

[tex]\[ x^2 = 121 \][/tex]

Taking the square root of both sides gives us two solutions:

[tex]\[ x = \pm 11 \][/tex]

Thus, the graphs intersect at[tex]\( (-11, 121) \) and \( (11, 121) \)[/tex].

In both cases, the intersection points are determined by finding the values of [tex]\( x \)[/tex] that satisfy the equation [tex]\( x^2 = k \)[/tex], where[tex]\( k \)[/tex]is the constant on the right side of the equation[tex]\( y = k \)[/tex].

The solutions are the positive and negative square roots of [tex]\( k \)[/tex], since [tex]\( x^2 \)[/tex] is equal to [tex]\( k \)[/tex] at these points."

Final answer:

Marie will need to cover an area of 2 1/2 square feet with fertilizer for her planter that is 1 1/2 feet long and 1 2/3 feet wide.

Explanation:

The question asks to calculate the area that needs to be covered with fertilizer for a planter with given dimensions.

Step-by-Step Solution:

Convert the dimensions of the planter into improper fractions for easier multiplication. The length is already given as an improper fraction (1 1/2 feet which is 3/2 feet). The width is 1 2/3 feet, which is 5/3 feet when converted.

Multiply the length by the width to find the area in square feet: (3/2) × (5/3) = 15/6 square feet.

Simplify the calculated area if necessary. The area 15/6 can be simplified to 2 1/2 square feet.

Therefore, Marie will need to spread fertilizer over an area of 2 1/2 square feet.

The vertex of a quadratic ax²+bx+c is located at x = -b/(2a). When the x² coefficient is negative, the vertex represents a maximum.

For P(x), the x-value of the maximum profit is ...

... x = -34/(2(-2))

The angle of elevation of the ramp (x) is approximately 58.9 degrees.

How to find the angle of elevation

To find the angle of elevation (x) of the ramp using the cosine function,

cos(x) = adjacent / hypotenuse

Given:

Adjacent side = 16 ft

Hypotenuse = 31 ft

Plug in these values into the formula

cos(x) = 16 / 31

To find x, take the inverse cosine (arccos) of both sides:

x = arccos(16 / 31)

Using a calculator,  arccos(16 / 31) is approximately 58.9 degrees.

Therefore, rounding to the nearest tenth of a degree, the angle of elevation of the ramp (x) is approximately 58.9 degrees.
