To pass the time on his travels, Ibn Battuta decides to run a test to see if the mean caravan size passing through a certain outpost is greater than 20 camels. He records the sizes of 7 caravans that pass through, assume that this represents a simple random sample of all caravans. After noticing that a smaller number of caravans are significantly larger than the rest of the population, he concludes the population is quite different from normal. He does not know the population's standard deviation. Which of the following describe which kind of test he should run?
a. He should run a Z-test.
b. He should run a T-test, and approximating it with a normal distribution would be appropriate.
c. He should run a T-test, and approximating it with a normal distribution would be inappropriate.
d. None of the above would be appropriate tests.

Answer:

1/8.

Step-by-step explanation:

9/8 = 9x

Cross multiply:

9x * 8 = 9

72x = 9

x = 9/72 = 1/8.

CHECK the answer:

9/8 = 9 * 1/8 = 9/8.  

Checks OK.

Answer:

n=6

Step-by-step explanation:

[tex]\frac{1}{2} n=3[/tex]

Multiply both sides by 2

2*1/2n=3*2

Simplify;

n=6

Answer: n=6

Step-by-step explanation:

6*1/2=3 so this is y n=6.

Answer:

Both are wrong.

Step-by-step explanation:

We have that:

Both decomposed the fraction [tex]\frac{13}{8}[/tex] into a sum of fractions. Whoever's decomposition sum has a value of [tex]\frac{13}{8}[/tex] is correct.

David:

[tex]1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}[/tex]

[tex]\frac{12}{8} \neq \frac{13}{8}[/tex], which means that David is wrong.

Patti

[tex]\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}[/tex]

[tex]\frac{11}{8} \neq \frac{13}{8}[/tex], which means that Patti is wrong.

So the answer is that both are wrong.

Answer:

c = 12.5903 as it is more accurate

Step-by-step explanation:

tan65 = 27/d , value of tan65 is 2.1445

2.1445 = 27/d

d = 27/2.1445

d = 12.5903

so answer would be c as it is more accurate than others.

Answer:

x= 4/16 stan

x=0.26 dec

Step-by-step explanation:

⬇ Hello! The answer would be down below! :) ⬇

x = 0 will be the answer.

Step-by-step explanation:

So, we start with [tex]\frac{3}{4} x = \frac{1}{5} x[/tex] .

For step 1 we should subtract [tex]\frac{1}{5} x[/tex]  on both sides.

[tex]\frac{3}{4} x - \frac{1}{5} x = \frac{1}{5} x - \frac{1}{5} x[/tex]

= [tex]\frac{11}{20} x = 0[/tex]

For step 2 we will multiply both sides by [tex]\frac{20}{11}[/tex].

[tex](\frac{20}{11})[/tex] x [tex](\frac{11}{20} x ) = (\frac{20}{11})[/tex] x [tex]\ (0)[/tex]

= x = 0

Answer:

70,176

Step-by-step explanation:

Given that

482 - 412 + 286 - 12 × 204

We need to solve the above equation

= 482 - 412 + 286 - 12 × 204

= 70 + 286 - 12 × 204

= 356 - 12 × 204

= 344 × 204

= 70,176

Hence, the answer to the given equation is 70,176

The same is to be considered and relevant

Answer:

∠1 = 67°

∠2 = 67°

∠3 = 113°

Step-by-step explanation:

∠3 = 113°

∠1 = ∠2

∠1 + ∠2 + ∠3 + 113° = 360°

∠1 = (360 - 113 - 113)/2 = 67°

Answer:

6.

Step-by-step explanation:

Since the y-value is the same, the two points make a horizontal line. You can think of it as a number line, where the first point is at -4 and the second is at 2. So, the distance between -4 and 2 is 6.

Answer:

[tex]V=1507.2\ feet^3[/tex]

Step-by-step explanation:

Given that,

The diameter of a cone-shaped sawdust, d = 24 feet

Height of the sawdust, h = 10 feet

We need to find the volume of the pile. We know that the volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]

Where

r is the radius of the sawdust, r = 12 feet

Put all the values,

[tex]V=\dfrac{1}{3}\times 3.14\times 12^2\times 10\\\\V=1507.2\ feet^3[/tex]

So, the volume of the pile is equal to [tex]1507.2\ feet^3[/tex].

Answer:

Not 100% sure but I'd say that the answers are possibly, 'A. X=2 or D. X=-2'.

Answer:

1.) up

2.) (-2,-5)

3.) x = -2

4.) (-2,-5)

5.) y = -5

6.) -∞ < x < ∞

7.) -5 < y < ∞

8.) (0,0)

9.) (0,0) and (-4,0)

10.) two solutions

Step-by-step explanation:

1.) because the parabola opens upward and the vertex is down

2.) the lowest point of the parabola is (-2,-5)

3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).

4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.

5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.

6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.

7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.

8.) The parabola first crosses the y-axis at the point (0,0)

9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)

10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

Answer:

d = 23.345235

Step-by-step explanation:

Answer: The answer is 194

Answer:

yes

Step-by-step explanation:

see attached graph - there are two real roots for y=2x^4-6x^2+10x-7

so 2x^4-6x^2+10x-7 can be expressed as:

(x - root1)(x - root2)(2x^2+Bx+C)

Answer:

Yes, it can be.

Step-by-step explanation:

Using solver program, the expression 2x^4-6x^2+10x-7 has:

two real roots at x≈-2.3888 and x≈1.1424

and

two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i

Because it has two real roots, the expression can be simplified.
