Answer:

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo  one is just a bigger copy of the other....

Step-by-step explanation:

Since this is a relation of the two side of each.. we can say the following...

\(\frac{6}{9}\) = \(\frac{4}{x}\)     where X = side  LA    soooo       solve for X  

 x *  \(\frac{6}{9}\) = 4   (move the X , to the other side of the '=' sign

x = 4 * \(\frac{9}{6}\)   ( yes.. we want to invert the fraction to move it to the other side )

x = \(\frac{36}{6}\)

x = 6

so side LA is 6    :)

Then the probability of randomly choosing a student with one sibling is:

P =  0.42

To get this probability, we need to take the quotient between the number of students that have a sibling and the total number of students.

On the table we can see that there are:

2 + 7 + 4 + 13 = 26 students in total.

And of these, the ones that have one sibling are:

7 students with only one sister

+

4 students with only one brother.

7 + 4 = 11

Then the probability of having one sibling is:

The next time all three lights will flash at the same time will be in 210 seconds, or 3 minutes and 30 seconds.

To find the time at which all three lights will flash at the same time, we need to find the LCM (Least Common Multiple) of the given times.

Prime factorizing each time, we get:

6 = 2 x 3

15 = 3 x 5

21 = 3 x 7

To find the LCM, we take the highest power of each prime factor that appears in any of the numbers:

2 x 3 x 5 x 7 = 210

After the 6-for-1 stock split, the stock price will be $16.41 per share, assuming no market imperfections or tax effects.

A stock split is a process in which a company increases the number of shares outstanding while proportionally reducing the price per share. In this case, the company plans a 6-for-1 stock split, which means that for every existing share, shareholders will receive six new shares.

To determine the post-split stock price, we divide the original stock price by the split ratio. The original stock price is $98.48, and the split ratio is 6-for-1. Therefore, we calculate:

$98.48 / 6 = $16.41

Hence, after the 6-for-1 stock split, the stock price will be $16.41 per share. This means that each shareholder will now hold six times more shares, but the value of their investment remains the same.

It is important to note that in practice, market imperfections, investor sentiment, and other factors can influence the stock price after a split. However, assuming no market imperfections or tax effects, the calculated value of $16.41 represents the theoretical post-split stock price.

The probability that the average final exam grade of the sample is between 75 and 80 is approximately 0.294, or 29.4%.

To solve this problem, we need to calculate the z-scores for the lower and upper bounds of the average final exam grade range, and then use the z-scores to find the corresponding probabilities from the standard normal distribution.

First, let's calculate the z-score for the lower bound:

z1 = (75 - 81.2) / (6.95 / sqrt(42))

z1 = -6.2 / (6.95 / sqrt(42))

z1 ≈ -2.512

Next, let's calculate the z-score for the upper bound:

z2 = (80 - 81.2) / (6.95 / sqrt(42))

z2 = -1.2 / (6.95 / sqrt(42))

z2 ≈ -0.528

Now, we can use the z-scores to find the corresponding probabilities using a standard normal distribution table or a calculator.

The probability that the average final exam grade of the sample is between 75 and 80 is equal to the probability of having a z-score between z1 and z2.

P(z1 < Z < z2) = P(-2.512 < Z < -0.528)

By looking up the probabilities corresponding to these z-scores from a standard normal distribution table or using a calculator, we find:

P(-2.512 < Z < -0.528) ≈ 0.294

the sample space for the basketball player's free throws is considered.

to determine the sample space, we need to identify all the possible outcomes for the number of successful free throws made by the player. In this case, each free throw can result in either a make or a miss, giving two possibilities for each attempt. With a total of 8 free throws, the sample space will consist of all the combinations of makes and misses, ranging from 0 makes to 8 makes.

Answer:

4 * 14 = 56

Step-by-step explanation:

56/2 = 28

28/2 = 14

14/2 = 7

7/7 = 1

56 = 2 * 2 * 2 * 7

56 = (2 * 2) * (2 * 7)

56 = 4 * 14

The maximum possible length of Av, where v is a unit vector, can be found by multiplying the largest singular value of the matrix A by the length of v. In this case, the largest singular value is 12.22.

To calculate the length of v, we can use the formula ||v|| = √(v₁² + v₂² + v₃² + v₄²), where v₁, v₂, v₃, and v₄ are the components of v.

Using the provided vector v = [-0.38, 0.27, -0.86, -0.31], we can calculate the length as follows:

||v|| = √((-0.38)² + 0.27² + (-0.86)² + (-0.31)²)

= √(0.1444 + 0.0729 + 0.7396 + 0.0961)

= √(1.053)

Therefore, the maximum possible length of Av is given by 12.22 * √(1.053), which is approximately 12.85 when rounded to two decimal places.

In summary, the maximum possible length of Av, where v is a unit vector, is approximately 12.85. This is obtained by multiplying the largest singular value of A (12.22) by the length of the unit vector v.

Step-by-step explanation:

the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.

we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.

Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.

the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

Because Molly swam across the pool 24 times, she swam a total of 24 * 25m = 600 meters.

600m in 40 minutes

Since 40 minutes * 1.5 = 60 minutes = 1 hour,

The Pythagorean triple (3, 4, 5) has one even length (4) and two odd lengths (3 and 5).

To create a Pythagorean triple using the Pythagorean identity (x^2 - y^2)^2 + (2xy)^2 = (x^2 + y^2)^2, we follow these steps:

Choose two numbers: Let's choose 3 and 4. We will assign 3 to x and 4 to y.

Determining x and y: The choice of which number to assign to x and y is arbitrary. In this case, we chose 3 for x and 4 for y. The important thing is to maintain consistency throughout the process.

Finding the Pythagorean triple: We substitute the chosen values into the Pythagorean identity:

((3^2 - 4^2)^2) + ((2 * 3 * 4)^2) = (3^2 + 4^2)^2

Simplifying the expression:

((-7)^2) + (24^2) = (9 + 16)^2

49 + 576 = 25^2

625 = 25^2

Therefore, the Pythagorean triple using the chosen numbers 3 and 4 is (3, 4, 5).

Answer:

The second number = 30

The first number = 25

The third number = 50

Step-by-step explanation:

Let

The second number = x

The first number = x - 5

The third number = 2(x - 5)

Total = 105

105 = x + (x - 5) + 2(x - 5)

105 = x + x - 5 + 2x - 10

105 = 4x - 15

105 + 15 = 4x

120 = 4x

x = 120/4

x = 30

The second number = x

= 30

The first number = x - 5

= 30 - 5

= 25

The third number = 2(x - 5)

= 2(30 - 5)

= 2(25)

= 50
