Answer:

Her conjecture is not correct

Step-by-step explanation:

Given

[tex]x^5 - 2 > x[/tex]

For [tex]x < -1[/tex]

Required

Determine if the conjecture is true

[tex]x < -1[/tex] implies that the values of x are:

-2, -3, -4, -5.....

Take any value of x and substitute in [tex]x^5 - 2 > x[/tex]

Let x = -3

[tex]x^5 - 2 > x[/tex] becomes

[tex]-3^5 - 2 > -3[/tex]

[tex]-243 - 2 > -3[/tex]

[tex]-245 > -3[/tex]

The above inequality is false;

Hence:

Her conjecture is not correct

Complete Question

CoStar would like to test if the vacancy rate for "warehouse" stores is more          than 8%. A type 1 error would occur if CoStar concludes that the vacancy rate was

A: not equal to 8% when, in reality, the proportion was equal to 8%

B: 8% or less when, in reality, the proportion was more than 8%

C: equal to 8% when, in reality, the proportion was 8% or less

D: more than 8% when, in reality, the proportion was 8% or less

Answer:

The correct option is  D

Step-by-step explanation:

From the question we are told that

CoStar would like to test if the vacancy rate for "warehouse" stores is more than 8%.

Hence

The null hypothesis is  [tex]H_o : p \le 0.08[/tex]

The  alternative hypothesis is  [tex]H_a : p> 0.08[/tex]

 Generally type 1 error occurs when null hypothesis is rejected while it is true

So Type I error would occur if CoStar concludes that the vacancy rate was more than 8% when, in reality, the proportion was 8% or less

Answer:

The correct answer is option A. A and C

Step-by-step explanation:

From the given situation above, here is the solution:

Friend A. 13 hours x $ 6.95 = $90.35 x 8 weeks = $722.80

Friend B. 15 hours x $ 5.85 = $87.75 x 8 weeks = $702

Friend C. 18 hours x $ 5.25 = $94.5 x 8 weeks = $756

Friend D. 11 hours x $ 7.80 = $85.8 x 8 weeks = $686.40

Therefore, the individuals who reached their goal of saving $720 for a vacation are friend A and friend C. The correct answer is option A. A and C.

Answer:

The correct answer is A.     A and C

Answer:

D

Step-by-step explanation:

First, let's define each of the terms.

Scalene refers to triangles whose three sides and three angles all have different measures.

Isosceles refers to triangles who has two equivalent angles and sides.

Right triangles are triangles with one right angle.

So we know that the triangle has one 90 degrees and 2 45 degree angles.

In other words, this is an isosceles triangle.

And since it also contains a 90 degree angle, it means that the triangle is an isosceles right.

The answer is D

Answer:

sale price = $145.56

Step-by-step explanation:

The regular price of one bicycle is $181.95

20% discount

sale price = original price - ( % discount x original price )

sale price = $181.95 - (0.20 * $181.95)

sale price = $181.95 - $36.39

sale price = $145.56

Answer:

Step-by-step explanation:

Given two vectors a = (4, 2, -4) and b = (4, -3, 2), the formula to be used to calculate the angles between both vectors is as expressed below;

[tex]a.b = |a||b| cos \theta[/tex] where [tex]\theta[/tex] is the angle between both vectors

a.b = (4, 2, -4). (4, -3, 2)

a.b = 4(4)+2(-3)+2(-4)

a.b = 16-6-8

a.b = 16-14

a.b = 2

Given |r| = √x²+y²+z²

|a| = √4²+2²+(-4)²

|a| = √16+4+16

|a| = √36

|a| = 6

Similarly;

|b| = √4²+(-3)²+2²

|b| = √16+9+4

|b| = √29

Substituting the parameters gotten into the formula to get the angle between the two vectors a and b we will have;

[tex]a.b = |a||b| cos \theta\\2 = 6*\sqrt{29} \ cos \theta\\ cos\theta = \dfrac{2}{6\sqrt{29} } \\cos\theta = \dfrac{1}{3\sqrt{29} }\\ cos\theta = 0.0619\\\theta = cos ^{-1}0.0619\\ \theta = 86.45^0 (to \ 2dp)[/tex]

Hence the angle between vectors a and b is 86.45°

Answer: Change it to decimal

Step-by-step explanation:

Converting it to decimal makes it easier to work with. It might make be an extra step, but in the long run of the problem it helps to make calculations accurate and easier to solve by working with simpler numbers. Converting to decimal form makes the number more precise for square roots, which are usually not whole numbers.

Answer:

-1

Step-by-step explanation:

We have our expression

6 - 4x = 7x - 9x + 8

Combine like terms

6 - 4x = -2x + 8

Add 2x to both sides, and subtract 6 from both sides

-2x = 2

x = -1

Answer:

-2x − 2 = 0 is the answer to this

Answer:

Step-by-step explanation:

Given a chord of distance of 15cm, if it is 9cm from the center of a circle, this means that the 9cm length will be projecting from the centre of the circle perpendicular to the chord and passing through its centre.

Since the radius of a circle is a line that is drawn from the centre of a circle to ts circumference, the set up will form a right angles triangle within the circle with the hypotenuse as the radius and the other two sides as the opposite and adjacent respectively. Using the Pythagoras theorem to get the length of the radius (hypotenuse);

hyp² = opp² + adj²

Let the opposite be the 9cm length

Adjacent will be half of the chord length = 15/2 = 7.5cm

Substituting this values into the formula we will have;

hyp² = 9² + 7.5²

hyp² = 81+56.25

hyp² = 137.25

hyp² = √137.25

hyp = 11.72

Hence the radius of the circle is approximately 11.72 cm long

Answer:

  2300

Step-by-step explanation:

When you multiply by 10, each place value moves one to the left: hundreds become thousands, tens become hundreds.

(2 hundreds 3 tens) × 10 = 2 thousands 3 hundreds

In numbers (standard form), this is ...

  230 × 10 = 2300

Answer:

The set of solutions are linearly independent because the wronskian is

e^(2ax) ≠ 0

Step-by-step explanation:

To show that the set of solutions {e^(ax), xe^(ax)} are linearly independent, we find the Wronskian of the set of solutions.

Wronskian of y1 and y2 is given as:

W(y1, y2) = y1y2' - y1'y2

y1 = e^(ax)

y1' = ae^(ax)

y2 = xe^(ax)

y2' = axe^(ax) + e^(ax)

W(y1, y2) = e^(ax)[axe^(ax) + e^(ax)] - ae^(ax).xe^(ax)

= (ax + 1)e^(2ax) - axe^(2ax)

= e^(2ax)

The wronskian of the given set of solutions is e^(2ax), which is not zero.

Because it is not zero, the set of solutions are linearly independent.

Answer:

l=22.5≅23 cm and w=7.5≅8 cm

Step-by-step explanation:

l=3w

p=60 cm

p=2(l+w)

60=2(3w+w)

60=2(4w)

60=8w

[tex]\frac{60}{8}=\frac{8w}{8}[/tex]

w=7.5≅8 cm

l=3w

l=3*7.5

l=22.5≅23 cm

check

p=2(l+w)

p=2(22.5+7.5)

p=2(30)

p=60 cm

The triangle is a right angles triangle and the unknown side is the hypotenuse which is the longest side of a triangle and the other two sides are the opposite and the adjacent

Using the Pythagoras theorem to find the length of the hypotenuse, we will have;

hyp²= opp²+adj²

hyp²= 15²+3²

hyp²= 225+9

hyp²= 234

hyp = √234
