Basil has 5 numbered cards. Two of the numbers are hidden. The mode of the 5 is 8. The mean of the 5 is 6. Work out the two hidden numbers​

The probability that the result was a 6 is P(A)=1/3 the die is tossed and we are told that a result is a number greater than 4.

A standard 6-sided die numbered 1 to 6 has 2 sides that meet the criterion of greater than 4, which are 5 and 6. So out of 6, there are 2 ways.

A die has 6 faces with the numbers 1,2,3,4,5 and 6 on each of the six faces. Now consider an unbiased die and the probability of any of the faces appearing in a single roll is 1/6.

So,

P(1)=P(2)=P(3)=P(4)=P(5)=P(6)=1/6

The numbers that are greater than 4 are 5 and 6

So it can be P(5) or P(6)=

P(5)+P(6)=2/6=1/3.

If you had stated at least a 4, then there are three chances which are to be 4,5,6 that meet the criterion, and the chance would be 3/6=1/2.

Hence, by the classical definition of probability, the probability of getting a number more than 4 in a single throw of a die is 1/3.

The scale of the drawing is obtained applying the proportions in the context of this problem.

The scale is defined as the division of the drawn length by the actual length.

Sarah's drawing has a scale factor of 1 inch to 0.1 inch, meaning that each inch she draws has an actual length of 0.1 inch.

The total price he has to pay for the clothes is 27.83

What is Percentage ?

Percentage can be defined as the product ratio of given value, total value and hundred.

Clothing price (100 percent) is 26 dollars and 50 cents, Added tax is 5 percent, and total cost is blank.

Darrien purchases some clothes for a total of $26.50, before tax. Sales tax in his state is 5 percent.

If Darrien spends 26.50, multiply that by 0.05 (26.50×0.05)

which is 1.325 which rounds to 1.33. $1.33 is the amount of tax he has to add. For the full price you would do 26.50+1.33 to get 27.83.

Therefore, The total price he has to pay for the clothes is 27.83

Step-by-step explanation:

Given quadratic equation:

Subtract 13 from both sides:

[tex]\implies \sf -108-13=(x-11)^2+13-13[/tex]

[tex]\implies \sf -121=(x-11)^2[/tex]

Switch sides:

[tex]\textsf{For $(g(x))^2=f(a)$ the solutions are $g(x)=\pm\sqrt{f(a)}$}[/tex]

[tex]\textsf{Apply radical rule} \quad \sqrt{ab}=\sqrt{a}\sqrt{b}:[/tex]

The recursive sequence that would produce the sequence 5, -17, 71, is by multiplying the previous term by -4 and adding 3.

A recursive sequence is a sequence where each term is defined as a function of the preceding term(s).

Given the sequence 5, -17, 71, ..., we can see that the next term in the sequence is obtained by multiplying the previous term by -4 and adding 3.

Therefore, the recursive sequence that produces this sequence is:

a_1 = 5

a_n = -4a_{n-1} + 3 where n > 1

This means that the first term of the sequence is 5, and each subsequent term is obtained by multiplying the previous term by -4 and then adding 3.

David's method to find the height of the tree is the use of the properties of similar triangles. The height of the tree is approximately 24 feet

According to the laws of reflection, we have;

Angle of incidence of the light from the top of the tree = Angle of the reflected light ray David sees.

The possible values in the question are;

Distance of the mirror from the tree = 37 feet

Distance from where David is standing to the mirror = 9.3 ft.

Height of his eyes above the ground = 6 ft.

Required: Height of Tree

Therefore;

The triangle formed by David's height, the reflected ray from the mirror and his distance from the mirror is similar to the right triangle formed by the tree, which by the relationship of similar triangles, gives;

[tex]\frac{9.3}{37}[/tex] = [tex]\frac{6}{Height of the Tree}[/tex]

Height of the tree × 9.3 = 6 × 37

Height of the tree = [tex]\frac{6 X 37}{9.3}[/tex] = 23.87 ≅ 24 feet

The curve achieves its greatest value for N=2 heads, which is the case where the outcome is most likely.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

m represents the slope.

x and y are the data points.

Next, we would determine the linear equation representing the data in table which passes through the points (1, 24) and (2, 36) by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 24 = (36 - 24)/(2 - 1)(x - 1)

y - 24 = 12(x - 1)

y = 12x - 1 + 24

y = t(n) = 12x + 23

When the value n = 4, the value of t(n) can be calculated as follows;

t(4) = 12(4) + 23

t(4) = 71.

When the value n = 5, the value of t(n) can be calculated as follows;

t(5) = 12(5) + 23

There is about a 27% chance of her sinking at least one ball on her break 14 or fewer times in 20 games and no convincing evidence that her average is less than 80%.

Based on the dot plot of the simulation results, it appears that the player's true probability of sinking at least one ball on her break is not 80%. In the simulation, there were only 12 trials out of 100 where the player sank at least one ball on her break 14 or fewer times in 20 games. This corresponds to a probability of 12/100, or 12%.

Since the player's actual performance in the last 20 games (14 out of 20) is less likely to occur than what was observed in the simulation, we can get the conclusion that the player has a lower than 80% chance of sinking at least one ball during her break.

Therefore, the correct conclusion is, "there is about a 27% chance of her sinking at least one ball on her break 14 or fewer times in 20 games. This result is not unusual and there is no convincing evidence that her average is less than 80%."

The question is incomplete. The complete question is 'The player’s true probability of sinking at least one ball on her break is 27%. another 100 simulated trials would show a much different outcome; therefore, we cannot draw any conclusions. it is most likely that she would sink at least one ball during her break exactly 16 times. there is about a 27% chance of her sinking at least one ball on her break 14 or fewer times in 20 games. this result is not unusual and there is no convincing evidence that her average is less than 80%.'

The system of equation are:

y = 1/2x...................(1)

2x + 3y = 28...................(2)

To solve the system of equation we use substitution method because the value of y is know from the equation 1. We can find easily the value of x by putting the value of y in equation 2.

Now putting the value of y in equation 2.

2x + 3(1/2x) = 28

2x + 3/2 x = 28

7/2 x = 28

Multiply by 2 on both side, we get

Step-by-step explanation:

The value of X is 40/3ft, Y is 27/4ft and Z is 469/27ft. The solution has been obtained by using the properties of triangle.

What is a triangle?

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. The triangle's three angles add up to a total of 180 degrees.

We know that if a line is parallel to the third side of the triangle, then the ratio of the sides is equal.

So,

⇒10/6 = x/8

⇒80/6 = x

⇒40/3 = x

Similarly,

⇒y/10 = 9/(40/3)

⇒y/10 = 27/40

⇒y = 27/4

Similarly,

⇒y/(y+10) = 7/z

⇒(27/4)/((27/4)+10) = 7/z

⇒469/27 = z

Hence, the value of X is 40/3ft, Y is 27/4ft and Z is 469/27ft.
