Answer:

C)

Step-by-step explanation:

It can't be A or B because the samples from 50 fish definitely wouldn't be equal to ALL the fish ever.

And it (more so) can't be D because you are finding the mean. that means that some catfish could weight 1 pound, and another could weigh 4, they would just cancel out.

That leaves C) with the only plausible answer.

The value of n is 50 and probability is 1/6, and 8.33 number of times Stacey would spin a 6.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Consider getting a 6 as a success. In this example, the chance of getting a 6 in a single spin is 1/6. The number of 6s in 50 spins can be considered a binomial random variable. Then, if X is the number of trials, we receive a score of 6 out of 50. Then there's the model below.

[tex]\rm P(X = k) = \binom{50}{K}\binom{1}{6}^k\binom{5}{6}^{50-k}[/tex]

From the binomial random variable of n trials with a probability of success of p.

We will have, n = 50, p = 1/6

Number of times Stacey would spin a 6 = 8.33

Thus, the value of n is 50 and probability is 1/6, and 8.33 number of times Stacey would spin a 6.

Answer:

see explanation

Step-by-step explanation:

(a)

∠ XBC = 55° because it corresponds to ∠ AXY

(b)

since XB = XC then Δ XBC is isosceles with base angles congruent, that is

∠ XBC = ∠ XCB = 55°

the sum of the 3 angles in Δ XBC = 180° , then

∠ BXC + 55° + 55° = 180°

∠ XBC + 110° =180° ( subtract 110° from both sides )

∠ XBC = 70°

Jenny has worked out the area of the whole circle using the formula π × r² where r is the radius length. She has assumed π is 3.14 which leads to her working of 3.14 × 10² = 314 units². She has to divide the total area by 4 to calculate the sector area.

Let's check

Area of sector

The intersection region will be between  -2 <x <2​ or x ∈ (-2, 2) if the two inequalities are x>-2  and -4 <x <2​

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have two inequalities:

x>-2  and

-4 <x <2​

or

x ∈ ( -2, ∞) and x ∈ (-4, 2)

The intersection region will be(from the graph)

x ∈ (-2, 2)

Thus, the intersection region will be between  -2 <x <2​ or x ∈ (-2, 2) if the two inequalities are x>-2  and -4 <x <2​

Answer:

2: 86

3:64

4: 77

6: 3

7:12

8: O=110 X:110

Step-by-step explanation:

Number 2 shows what is called a central angle. Central Angles are equivalent to the ark length

Number 3 shows an Inscribed angle. These angles are half of the ark but in your question, it is twice the angle measurement

Number 4 you want to divide the ark length by two when the angle is not given. And when the angle is given you want to mutilate by two

Number 6 is Overlapping Ark which means they are both congruent to each other because the ark is equivalent to each other.

Number 7 is x=12 because 5x+12 is twice the measure of 3x

Number 8 o=110 because a circle has 360 degrees so you want to add them up and then subtract that from 360. x is also 110 degrees because it is a central angle, which is the same amount of degrees as the ark length.

Step-by-step explanation:

The net force is equal to the differences in magnitudes of the forces acting on it.

Take the left direction to be positive (+) and right direction to be negative (-).

Solving :

Net Force = Force (left) - Force (right)

Net Force = 10 + 20 - 5

Net Force = 30 - 5

Answer:

C: Addition then multiplication can be used to solve the problem

Step-by-step explanation:

The solution to the system of equation 8x -4y = -24, 4x - 12y = -32 is x = 19 / 8 and y = 5 / 4

The solution of the system of equation can be found as follows:

8x -4y = -24

4x - 12y = -32

Multiply equation(ii) by 2

8x - 4y = -24

8x - 36y = -64

32y = 40

y = 40 / 32 = 5 / 4

8x - 4(5  / 4) = -24

8x - 5 = -24

8x = -24 + 5

8x = 19

x = 19 / 8

An inferential statistic is one that makes inference or predictions about a population based on a sample.

In this problem, an inferential statistic is the sample proportion of 15% for the population of Lyon, France or Europe(as Lyon is in France and France in Europe).

In option C, the inference is for the sample and not for any population, hence it is not an inferential statistic.

Answer:

Step-by-step explanation:

Use the formula:

Plug In:

22,411 ÷ 2 - 260

Solve:

Answer is L = 10,945.5 inches
explain: perimeter is all 4 sides added together

We know one side is 260
we know the perimeter is 22,411

260 + 260 + L + L = 22,411
combine like terms

520 + 2L = 22,411
subtract 520 from both sides to isolate 2L

2L = 21,891
divide both sides by 2 to isolate L

L = 10,945.5 inches

Answer:

Mean - 17.222222222222

Median - 17

Mode - 12

Step-by-step explanation:

lets arrange this is least to greatest.

2, 4, 12, 12, 17, 18, 28, 29, 33

to find the mean(even though you dont need it), you add all the numbers up and devide by the amount of numbers.

so -> 2 + 4 + 12 + 12 + 17 + 18 + 28 + 29 + 33 = 155

and there are 9 numbers, so 155 / 9 = 17.2 and a lot more 2s

to find the median, you arrange from least to greatest vice versa, then find the middle number.

2, 4, 12, 12, 17, 18, 28, 29, 33

the middle number is 17, so the mean is 17

to find the mode, you have to find the number that is most repeated.

2, 4, 12, 12, 17, 18, 28, 29, 33

the number that is repeated the most is 12, so your mode is 12.

The height of the cylinder is 19 meters if the volume of 475pie cubic meters and the radius is 5 meters.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

We have a volume of the cylinder:

V = 475π cubic meter

The radius r = 5 meters

475π = π(5)²h

h = 19 meters

Thus, the height of the cylinder is 19 meters if the volume of 475pie cubic meters and the radius is 5 meters.

Answer:

Approximately [tex]14,\!500\; {\rm cm^{3}}[/tex].

Step-by-step explanation:

The radius of a sphere is the same as the radius of the great circle of that sphere.

Thus, in this question, it would be possible to find the radius of the sphere by finding the radius of the great circle.

The circumference of a circle of radius [tex]r[/tex] is [tex]2\, \pi \, r[/tex]. In this question, it is given that the circumference of this great circle is [tex]95\; {\rm cm}[/tex]. Thus, the radius of this great circle would be:

[tex]\begin{aligned}r &= \frac{95\; {\rm cm}}{2\, \pi} \approx 15.1197\; {\rm cm}\end{aligned}[/tex].

Thus, radius of the sphere in this question would also be approximately [tex]15.1197\; {\rm cm}[/tex].

The volume of a sphere of radius [tex]r[/tex] is [tex](4/3)\, \pi\, r^{3}[/tex]. Thus, the volume of this sphere of radius [tex]r = 15.1197\; {\rm cm}[/tex] would be approximately:
