Step-by-step explanation:

Answer:

9

Step-by-step explanation:

if you add 5,8,9,11,and 7 you get 40 then you need to divide it by 5 because their are 5 numbers so then 40 divided by 5 is 8 so the number is 9

Final answer:

To determine the missing number in the data set with a mean of 8, we set up the equation 8 = (5 + 8 + 11 + x) / 4. Solving for x, we find that the missing number is 8.

Explanation:

To find the missing number in the data set 5, 8, 11, ?, where the mean is 8 points, we can use the formula for the mean of a data set. The mean is the sum of all data points divided by the number of points. Since we know the mean and three of the four numbers, we can create an equation to solve for the missing number:

Mean = (Sum of all data points) / (Number of data points)

8 = (5 + 8 + 11 + x) / 4

Now, solve for x:

8 * 4 = 5 + 8 + 11 + x

32 = 24 + x

x = 32 - 24

x = 8

Therefore, the missing number is 8.

No, basically because it fails the vertical line test. The correct option is C.

The vertical line test determines whether a relationship between two variables defines a function. If and only if vertical lines intersect the graph at least once, a relation is a function.

The graph fails the vertical line test because vertical lines intersect it at more than one point.

This means that some x-values correspond to multiple y-values, which violates the definition of a function.

In other words, for each x-value, there should be only one y-value, but this is not the case for all x-values. As a result, the graph does not depict a function.

Thus, the correct option is C.

Final answer:

The requried there are 19 ways to choose a student who is not a seventh grader.

Explanation:

In this scenario, we need to find the ways of choosing not a seventh grader from the gym class.

To do this, we calculate the total number of ways to select a student from the gym class and then subtract the ways of selecting a seventh grader.

The total number of ways to select a student from the gym class is 12 (sixth graders) + 14 (seventh graders) + 7 (eighth graders) = 33.

The number of ways of selecting a seventh grader is 14 (since there are 14 seventh graders).

Therefore, the number of ways of not choosing a seventh grader is 33 - 14 = 19 ways.

So, there are 19 ways to choose not a seventh grader.

Question:

You flip a fair coin. What is P(tails)?

If necessary, round your answer to 2 decimal places.

Answer:

P(tail) = 0.5

Step-by-step explanation:

Given:

A fair die

Required

P(Tails)

A fair die has 2 sides, the head and the tail; each of the sides have equal probability.

The number of head in a die is 1 and the number of a tail in a die is 2.

Let P(tail) represent the probability of obtaining a tail.

P(tail) is calculated by number of tail divided by number of sides of a die.

Hence, P(tail) = ½

P(tail) = 0.50

"The probability of getting tails when flipping a fair coin is [tex]\(\frac{1}{2}\)[/tex] or 0.5.

A fair coin has two equally likely outcomes: heads or tails. Since a fair coin has no bias towards either side, the probability of landing on tails is the same as the probability of landing on heads.

The probability of an event E, denoted as P(E), is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, the event E is getting tails. There is one favorable outcome for getting tails, and there are two possible outcomes in total (heads or tails).

Therefore, the probability of getting tails, P(tails), is given by:

[tex]\[ P(\text{tails}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} = \frac{1}{2} \][/tex]

This fraction simplifies to 0.5, which is the correct probability of getting tails when flipping a fair coin. There is no need to round to 222 decimal places as the probability is exact.

The terms that Misha should combine are 3x – 2x and –8 – 7

Step-by-step explanation:

Misha have the equation : 3x-2(x+3) = 4(x-2)-7

After applying distributive property, a(b+c) = ab+ac

3x - 2x - 6 = 4x - 8- 7 ..............(1)

Now, we need to combine the like terms, like terms are the terms having the same coefficient and combining them means to combine their coefficients.

In equation (1), 3x and -2x are like terms as it have the same coefficient x

Hence we will solve them and get (3-2)x = x

Similarly, -8 and -7 can be solved and we get -7-8 = -15

Now, the equation becomes, x-6 = 4x-15

Then, again collecting the like terms on L.H.S  and R.h.s and then solving, we get

4x - x = 15-6

3x = 9

x = 3

Step-by-step explanation:

To find the opening price of the stock, we can subtract the 5% gain from the current price. The opening price of the stock in the beginning of the day was approximately $36.47.

To find the opening price of the stock, we need to deduct the 5% gain from the current price of $34.65.

Let x be the opening price.

Since the stock gained 5%, the opening price minus 5% of the opening price equals the current price: x - 0.05x = 34.65.

Simplifying the equation, we get 0.95x = 34.65. To solve for x, divide both sides of the equation by 0.95.

The opening price of the stock in the beginning of the day was approximately $36.47.

To find areas and circumferences of circles using similarity, we scale proportions from known circles to unknown circles. The diameter is twice the radius (d = 2r), allowing us to use formulas C = 2πr for circumference and A = πr^2 for area.

To determine the area and circumference of circles using similarity, we can scale up or down from a known circle to an unknown one. The relationships between circles of different sizes but with proportional radii allow us to use the similarity concept. For example, if a small circle has a radius that is half the radius of a larger circle, the area and circumference will also be in proportion to the squares and the linear dimensions, respectively.

The radius (r) and diameter (d) of a circle are directly related by the equation d = 2r. This means that diameter is twice the radius. Given the radius, we can determine the circumference of a circle (C = 2πr) and its area (A = πr2) easily. The role of π (approximately 3.14159) is critical as it provides the constant of proportionality in these equations.

Step-by-step explanation:

We need to use some properties of an isosceles triangle and the Pythagorean Theorem.

First, the vertical line down the middle of the triangle is the height, which means the angle is makes with the base is 90 degrees and it bisects the base. So, we have two right triangles, each with a height of 6 and with a base of 4/2 = 2.

We can now use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, a = 6 and b = 2 and x = c, so:

a² + b² = c²

6² + 2² = x²

x² = 36 + 4 = 40

x = √40

Thus, the answer is A.

Answer:

A

Step-by-step explanation:

This triangle contains two congruent right angle triangles

x² = 6² + 2²

x² = 36 + 4

x² = 40

x = sqrt(40)

x = 4sqrt(10)

Answer:

A(p)  = 84 ft³

Step-by-step explanation:

Volume of regular prism is equal to V(p):

V(p)  = Area of the face * h

we know h = 3 ft

A regular hexagonal prism has 6 equal sides forming its face.

Finding the area (A₂) of a triangle formed  by center of the prism, straight lines between the center and two adjacents vertex and side between these two vertex, and then multiply that area by 6 (number of equal triangles inside hexagonal prism) we get the area of the face, but  we need further consideration, the triangle described above, has doble area of (A₁), the triangle formed by apothem, half side, and straight line between center of the face and the vertex, therefore.

Area of small triangle = base * height

A₁  = (1/2) * 4 * 3,5

A₁  =  2*3,5

A₁  = 7 ft²

A₂  = 2* 7    

A₂  = 14 ft²

Finally volume  of the hexagonal prism is:

V(p) = 6 * 14

A(p)  = 84 ft³

The height of the cone is approximately 7.01 centimeters.

We know the volume (V) is 66 cubic centimeters and the radius (r) is 3 centimeters. Substitute these values into the formula:

V = 1/3πr²h

66 = 1/3 × π × 3² × h

Simplify the equation:

Multiply both sides by 3:

200 = π × 9 × h

Cancel out the common factor of 9:

200/9 = π × h

Solve for the height (h):

Divide both sides by π:

h = 200/9π

Then, we have that;

h ≈ 7.01 cm

Therefore, the height of the cone is approximately 7.01 centimeters.
