The proportion of wand prices as per normal distribution are lower than the price of the blackthorn wand is equal to 0.1151.

As given in the question,

Mean of the set of magical wand price 'μ' = 50dollars

Standard deviation 'σ' for normal distribution = 4 dollars

Price of blackthorn wand 'X' = 45.20 dollars

z-score = (x - μ)/σ

Proportion of wand prices be 'x'

P(x < X)

=P( x< 45.20)

=P [(x - μ)/σ < (X - μ )/σ]

=P[ z < (45.20 - 50)/4]

=P( z < -1.2 )

= 0.11507

=0.1151

Therefore, the proportion of the wand prices which are lower than the price of blackthorn wand using normal distribution is equal to 0.1151.

The complete question is:

A set of magical wand prices are normally distributed with a mean of 50 dollars and a standard deviation of 4 dollars. A blackthor wand has a price of 45.20 dollars. What proportion of wand prices are lower than the price of the blackthorn wand? You may round your answer to four decimal places.

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

                                            P = (-3.5, 1.25)

Hence, the coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25).

What are the coordinates of the point 3/4 of the way from A to B?

Options A and D are both correct. UV = 14 feet and mTUV = 45 degrees D. ST = 20 feet, UV = 14 feet, and mUST = 98 degrees by using congruence of triangles.

Two triangles are congruent if their corresponding sides are the same length and their corresponding angles are the same size.

According to the SAS criterion for triangle congruence, two triangles are congruent if they have two pairs of congruent sides and the included angle (the one between the congruent sides) in one triangle is congruent to the included angle in the other triangle.

Given

See the attachment for the triangle.

What evidence do you have?

SAS is used by STU and VTU.

To demonstrate their resemblance, we must examine the corresponding sides and angles of both triangles.

To begin, UST must equal UVT.

As a result, UST=UVT=98⁰.

Then, UV must equal US.

So:

UV = US = 14⁰

Furthermore, ST must equal VT.

So:

Furthermore, ST must equal VT.

As a result, ST = VT = 200.

Finally, TUV must be equal to TUS.

So: TUV = TUS = 450

Options A and D are both correct. UV = 14 feet and mTUV = 45 degrees D. ST = 20 feet, UV = 14 feet, and mUST = 98 degrees.

The equation of the line is y = (2/3)x + 4

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line.

y = m(1)x + c

The line is parallel to y = (2/3)x + 1

It is in the form of y = m(2)x + c

This means,

m(1) = m(2)

m(1) = 2/3

Now,

The line passes through the point (3, 6).

(3, 6) = (x, y)

y = mx + c

6 = (2/3)3 + c

6 = 2 + c

Answer:3.53% probability that the rat fails the maze 6 times in a row, and then succeeds on his 7th attempt

Step-by-step explanation:For each time that the rat goes through the maze, there are only two possible outcomes. Either he fails it, or he succeds. The trials are independent. So we use the binomial probability distribution to solve this question.

Binomial probability distribution:The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.In which  is the number of different combinations of x objects from a set of n elements, given by the following formula.And p is the probability of X happening.

What is the probability that the rat fails the maze 6 times in a row, and then succeeds on his 7th attempt?Missing on the first six, each with 70% probability(P(X = 6) when p = 0.7, n = 6).Succeeding on the 7th attempt, with p = 0.3. So 3.53% probability that the rat fails the maze 6 times in a row, and then succeeds on his 7th attempt

Her pay will increase by 20% as a result of the percentage being the difference from the original.

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 78% grade if you answered 78 of 100 questions correctly on a test (78/100).

According to the given Information

Another name for the percentage is the signifying hundredths. As a result, 2% is equal to two hundredths, or 2%=2/100=0.02.

According to what has been stated,

Original price: $10

Pay increase = $12

% growth = (10 x 100 - (12 - 10))

The vector [v] whose direction is same as that of vector [u] is given as -

[v] = -24i + 45j.

We have the a vector [v] with the given magnitude and the same direction as u.

We can write vector [u] as -

[u] = - 8i + 15j

Unit vector {u} along vector [u] -

{u} = [u] / |u|

{u}  = (- 8i + 15j)/17

We can write vector [v] as -

[v] = 51 x (- 8i + 15j)/17

[v] = 3(- 8i + 15j)

[v] = -24i + 45j

Therefore, the vector [v] is given by [v] = - 24i + 45j.

The amount of stock that is wasted is given as follows:

1 - 21/64 inches.

The total amount of stock is given as follows:

9 - 7/16 inches long = 144/16 - 7/16 = 137/16 inches long.

The total amount of stock used for the two punches is given by the sum of the two amounts, as follows:

4 - 1/64 + 4 - 3/32 = 8 - 7/64 = 505/64

Then the amount wasted is given by the subtraction of the total amount by the amount used, as follows:

137/16 - 505/64 =  548/64 - 505/64 = 43/64.

The decimal of this is of:

The equation of the parabola is y = -0.25(x - 4)² + 16 and he reaches 12 feet outwards when he hits the water

From the question, we have the following parameters that can be used in our computation:

Initial position = 12 feet above the surface

Maximum height = 18 feet at 4 feet outward

These parameters mean that

(h, k)  = (4, 16) -- vertex

(x, y) = (0, 12)

A parabola is represented as

y = a(x - h)² + k

So, we have

y = a(x - 4)² + 16

Also, we have

12 = a(0 - 4)² + 16

This gives

12 = 16a + 16

So, we have

16a = -4

Divide

a = -0.25

Substitute a = -0.25 in y = a(x - 4)² + 16

y = -0.25(x - 4)² + 16

When it hits water, y = 0

So, we have

-0.25(x - 4)² + 16 = 0

This gives

0.25(x - 4)² = 16

So, we have

(x - 4)² = 64

Take square roots

x - 4 = 8

So, we have

x = 12

Hence, it is 12 feet outwards

Answer:

x >= 9.

Step-by-step explanation:

To earn a free movie ticket, Liam needs at least 160 points. He already has 50 points from signing up, so he needs 160 - 50 = <<160-50=110>>110 more points.

Each visit to the movie theater earns Liam 12.5 points, so the inequality representing the number of visits he needs to make is:

12.5 * x >= 110

To solve this inequality, we need to divide both sides by 12.5:

12.5 * x / 12.5 >= 110 / 12.5

This simplifies to:

x >= 8.8

Thus, Liam needs to make at least 9 visits to the movie theater to earn his first free movie ticket.

Therefore, the solution to the inequality is x >= 9.

Each part of the question is answered above and the angles are given below.

Given are the angles as mentioned in the question.

[1] -

Since, angle [1] and angle [4] are vertically opposite angles, we can write-

3x + 14 = 5x - 52

14 + 52 = 5x - 3x

2x = 66

x = 33

∠1 = 3x + 14 = 3 x 33 + 14 = 99 + 14 = 113°

∠1 = 113°

[2] -

Since, angle [A] and angle [B] are supplementary angles, we can write-

(3x + 8) + {(2/3)x + 62} = 180

3x + 8 + 62 + (2/3)x = 180

3x + (2/3)x = 110

x{3 + 2/3} = 110

x{(9 + 2)/3} = 110

(11/3)x = 110

x = (110 x 3)/11

x = 30

∠A = 3x + 8 = 3 x 30 + 8 = 98°

∠A = 98°

∠A = (2/3)x + 62 = 2/3 x 30 + 62 = 82°

∠B = 82°

[3] -

Since, angle [2] and angle [3] are  vertically opposite angles, we can write -

13x + 27 = 9x + 59

13x - 9x = 59 - 27

4x = 32

x = 8

∠2 = 13x + 27 = 13 x 8 + 27 = 104 + 27 = 131°

∠2 = 131°

∠3 = 9x + 59 = 9 x 8 + 59 = 72 + 59 = 131°

∠3 = 131°
