Answer:

h0:u ≥ 21.1

h1: u < 21.1

t statistics = -2.632

pvalu = 0.007

there is sufficient evidence to support claim

Step-by-step explanation:

null hypothesis

h0 = u≥21.1

alternative = u < 21.1

to get test statistics

barx - u / s/√n

= 19.4 - 21.1 / 3.23/√25

= -2.632

we calculate for the p value given this test statistics and the degree of freedom = 25-1 = 24

lest tailed p value = 0.0073 this is approximately 0.007

p value is less than the level of significance so we reject h0

we conclude that we have enough evidence to support h1, mean tar conent is less than 21.1

Answer:

  b⁶

Step-by-step explanation:

The question tells you how to work it: use the relations you studied.

Here, you have the power of an expression with an exponent. The exponents multiply.

  [tex]\text{Rule: }(a^b)^c=a^{bc}\\\\\text{Appication: }(b^3)^2=b^{3\cdot2}=\boxed{b^6}[/tex]

_____

Additional comment

A coefficient is used to indicate repeated addition: 3x = x + x + x.

An exponent is used to indicate repeated multiplication: x³ = x·x·x.

This is still true when the exponent is applied to an expression with an exponent:

  (b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2

Of course, each of these indicates repeated multiplication, so we really have ...

  (b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b

And this can be simplified using an exponent to show the repeated multiplication:

  = b⁶

Then, by going the long way around, we arrive at ...

  (b³)² = b⁶

all of the brackets first

Answer:

Step-by-step explanation:

Those consecutive angles must sum to 180 degrees.

7x+9+7y-4=180

7x+7y+5=180

7x+7y=175

x+y=25

x=25-y

We also have

11x-1+2y+5=180

11x+2y+4=180

11x+2y=176, using x=25-y that we found above makes this

11(25-y)+2y=176

275-11y+2y=176

-9y+275=176

-9y=-99

y=11, and since x=25-y

x=25-11

x=14

Finally

z+7x+9=180

z+7x=171

z=171-7x, we found that x=14 earlier so

z=171-7(14)

z=171-98

z=73

So the three values are

x=14, y=11, and z=73 degrees.

Answer:

A) Diameter = 9.03 ft

B) Circumference = 28.35 ft

Step-by-step explanation:

64 = πR²

R² = 64/3.14 = 20.38

Radius = 4.51 ft

Diameter = 2(4.51) = 9.03 ft

Circumference = 9.03 x 3.14 = 28.35 ft

Answer:

x = 10

Step-by-step explanation:

3x - 5 = 2x + 5

3x - 5 + 5 = 2x + 5 + 5

3x = 2x + 10

3x - 2x = 2x - 2x + 10

1x = 10

x = 10

Answer:

[tex]cos(x)[/tex]

Step-by-step explanation:

Let's recall the definition of the trigonometric identities in place:

[tex]cot(x)=\frac{1}{tan(x)} =\frac{cos(x)}{sin(x)}[/tex]  and

[tex]csc(x)=\frac{1}{sin(x)}[/tex]

Then, we substitute and simplify as follows:

[tex]\frac{cot(x)}{csc(x)}=cot(x)*\frac{1}{csc(x)}=\frac{cos(x)}{sin(x)}*sin(x)=cos(x)[/tex]

Step-by-step explanation:

Answer:

Equation of parabola:  8*(y - 2) = (x - 3)^2

or

y = (1/8)*(x - 3)^2 + 2

Step-by-step explanation:

focus at (3,4) and its directrix y = 0.

Focus equation:  (h, k + c) = (3, 4)

Directrix equation  y =  k - c = 0

so  h = 3,   k + c = 4,   k - c = 0

Solve  the system :  k + c = 4 and k - c = 0

add the equations together:     k + c + k - c = 4 + 0

2k = 4

k = 2

so   k + c = 4,    2 + c = 4,   c = 2

4c (y - k) = (x -  h)^2

4*2 *(y - 2) = (x - 3)^2

8*(y - 2) = (x - 3)^2

Answer:

£32 and £32

Step-by-step explanation:

The computation of the amount that should be left and equally distributed is shown below:

The cost of hotel for one night is £84

Brenda has make a deposit of £20

So, the remaining amount left is

= £84 - £20

= £64

Now this amount should be equally distributed between them i.e. £32 and £32

Ax+ By = C for x

Ax = C - By

x = (C - By)/A

Done.

Due to not knowing many there are in the container, here is how to get the answer on a calclator:

*Number of amount in container* Divided by 5

Then get that original container amount then subtract the number you got from the previous equasion

This is my tactic and it always works for me

Answer:

About 207 inches

Step-by-step explanation:

The circumference of a circle is given by the formula ...

 C = πd . . . . . where d represents the diameter

The circumference of the tire is the distance the truck will move when the tire makes one revolution. That distance is ...

 C ≈ 3.1416×(66 in) ≈ 207.35

The truck will travel about 207 inches for each revolution of the tire.

Answer:

Nerf football cost is $9.48.

Step-by-step explanation:

Total order made by Mr. DiCanio = $97.23

A playground ball cost $17.25 each, so that the cost of 4 playground balls can be determined by;

4 playground balls = $17.25 x 4 = $69.0

A package of 10 jump ropes = $18.75

Cost incurred on the items above = $69.0 + $18.75

                                                         = $87.75

Thus,

The cost of 1 Nerf football = $97.23 - $87.75\

                                           = $9.48

Therefore, the cost of Nerf football is $9.48
