Answer:

The null hypothesis is [tex]H_{0}: \mu = 8[/tex], and the alternative hypothesis is [tex]H_{a}: \mu < 8[/tex]

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different of the value tested at the null hypothesis.

Claims to lose an average of 8 pounds the first month

This means that the null hypothesis is [tex]H_{0}: \mu = 8[/tex]

If the FTC finds evidence that the average is less than 8 pounds, the agency will file a lawsuit against the company for false advertising.

FTC tests if the mean is less than 8, so the alternate hypothesis is [tex]H_{a}: \mu < 8[/tex]

Step-by-step explanation:

solve for  x by simplifying both sides of the equation, then isolating the variable

Answer:

505.5kg

Step-by-step explanation:

To convert 0.5t5kg5hg to kilogram​, first we need to convert 0.5t and 0.5hg to kg as shown;

1t = 1000kg

0.5t = 0.5 *1000

0.5t = 500kg

Similarly

1hg = 0.1kg

5hg = 5 * 0.1

5hg = 0.5kg

Adding up;

0.5t5kg5hg = 500kg+5kg+0.5kg

0.5t5kg5hg = 505.5kg

Hence the conversion to kg is 505.5kg

Answer:

x² + 4x

Step-by-step explanation:

Area of the rectangle = length × width

length = x + 4

width = x

Therefore,

Area = x(x + 4)

Area = x*x + x*4

x² + 4x

Answer:

a)  0 , 1

b) 0.56 , 0.06

Step-by-step explanation:

X = 0.2

Y = 0.3

Find the distribution of X + Y

a) All the possible values of  X + Y

The possible values of X + Y  are ; 0,1

b) The probabilities that X + Y takes each of the values

P(X+Y=0 ) = ( 1-0.2 )*(1-0.3) = 0.56

P( X +Y = 1) = 0.2*0.3 = 0.06

Answer:

-3

Step-by-step explanation:

The limit of the given function f(x) = 5[tex]x^{4}[/tex] – x2 + 6x – 1 approach negative 1 will be -3 so correct option will be (A).

Limit, a nearness in mathematical notion, is largely used to give values to some functions at locations that were usually not given or defined, in a manner consistent with neighboring values.

In another word, limit is a mathematical concept in which we find out the value of any function at a point by its adjacent very close point.

Because the value of that function at that point doesn't define.

For example, limits tend to 0 of sine x, limits tend to infinite of cosx.

Given that the function

5[tex]x^{4}[/tex] – x2 + 6x – 1

Limit is from x is tends to -1

[tex]\lim_{x \to \-1} f(x)[/tex] = 5(-1)⁴ - (-1)² +6(-1) -1

⇒ -3 hence it will be the correct answer.

Answer:

60

Step-by-step explanation:

I think that is the best choice sorry if i got it wrong.

Answer:

60 degrees

Step-by-step explanation:

Angle 1 is already 55 degrees, if you move the y line 5 degrees clockwise then it equals 60 degrees. Angle 1 and 3 are vertical angles so they are equal, if angle 1 is 60 degrees after we move the line then angle 3 is also 60 degrees

Answer:

Cos 2theta = -3/5

Step-by-step explanation:

Given that;

tan theta = -2

tan theta = -2/1 = opp/adj

hyp^2 = (-2)^2+1^2

hyp = √4+1

hyp = √5

sin theta = opp/hyp

sin theta = -2/√5

Cos theta = adj/hyp

Cos theta = -2/√5

Cos 2theta = 1-2sin^2 theta

Cos 2theta = 1- 2(-2/√5)^2

Cos 2theta = 1- 2(4/5)

Cos 2theta = 1- 8/5

Cos 2theta = (5-8)/5

Cos 2theta = -3/5

Answer:

[tex]EF = 12[/tex]

Step-by-step explanation:

Given

[tex]EF= n + 8[/tex]

Required

Find CN

From the attachment:

[tex]EF = CD\ and\ CD = DA[/tex]

Where

[tex]CA = CD + DA[/tex]

This means that:

[tex]CA = CD + CD[/tex]

[tex]CA = 2CD[/tex]

or

[tex]CA = 2*EF[/tex]

This gives:

[tex]6n = 2*(n+8)[/tex]

Open bracket

[tex]6n = 2n+16[/tex]

Collect anf simplify like terms

[tex]4n = 16[/tex]

[tex]n= 4[/tex]

So:

[tex]EF= n + 8[/tex]

[tex]EF = 4 + 8[/tex]

[tex]EF = 12[/tex]

Answer:

[tex]6\sqrt2\\OR\\8.48528137[/tex]

Step-by-step explanation:

The area of a sector of a circle is found by:

[tex]A = \frac{\theta*r^2}{2}[/tex]

The question asks for the radius so the equation above can be repurposed

[tex]r = \sqrt\frac{2A}{\theta}[/tex]

A = 3pi

angle = pi/12

[tex]\frac{6\pi}{\pi/12} = \frac{72\pi}{\pi} = 72[/tex]

[tex]\sqrt{72} = 6\sqrt2 = 8.48528137[/tex]

Answer:

224 in.²

Step-by-step explanation:

The tent has a shape of a triangular prism. So, we are looking for the Lateral surface area of a triangular prism.

Lateral surface area of a triangular prism = Perimeter of base × height of prism

Perimeter of base = 5 + 6 + 5 = 16 in.

Height of prism = 14 in.

Plug in the values

Lateral Surface Area = 16 × 14 = 224 in.²
