The value of x is 12.82, the value of z is 40.25.

Using Pythagorean theorem

50²= 39² + y²

y²= 2500- 1521

y= 32.28

Again Using Pythagorean theorem

z²= y²+ x²

z²- x²= 979

and, (39 + x)² = 50² + z²

(39 + x)² = 50² + (x² + 979)

1521 + 78x + x² = 2500 + x² + 979

78x = 1000

x ≈ 12.82

Substituting this value of x back into the first equation, we get:

z² - x² = 979

z² - (12.82)² = 979

z² ≈ 1620.12

Taking the square root of both sides, we get:

z ≈ 40.25

Therefore, the value of x is 12.82, the value of z is 40.25.

m = 1  :  [tex]\frac{4}{m} +1[/tex]  =>  [tex]\frac{4}{(1)} +1[/tex] = 4 + 1 = 5

The proportion is solved and value of a = 9 and constant is k =45

Given data ,

If a is inversely proportional to b, it means that their product remains constant

a * b = k

where "k" is the constant of proportionality.

Given that a = 1.5 when b = 30, we can substitute these values into the equation:

1.5 * 30 = k

k = 45

Now, we can use the value of k to determine the value of "a" when b = 5:

a * 5 = 45

Dividing both sides by 5:

a = 45 / 5

a = 9

Hence , proportionality constant is k = 45 and when b = 5, the value of "a" is 9

The probability of rolling a number other than 1 on a standard number cube is 5/6.

When rolling a standard number cube, there are six equally likely outcomes, one for each face of the cube. To find the probability of rolling a number other than 1, we need to determine the number of              favorable outcomes and divide it by the total number of possible outcomes.

In this case, the favorable outcomes are rolling any number from 2 to 6, which gives us five possibilities. Therefore, the probability of rolling a number other than 1 is 5 out of 6.

Expressing this as a fraction, the probability can be written as 5/6. This means that out of all the possible outcomes, there is a 5/6 chance of rolling a number that is not 1.

The water level in the aquarium will rise by 18 cm.

The volume of water in the aquarium before adding the sand is given by:

Volume = (1/2) x 23 cm x 15 cm = 172.5 cm³

When the sand is added, its volume is 2350 cm³. Therefore, the new volume of water and sand in the aquarium is:

 = 172.5 cm³ + 2350 cm³

 = 2522.5 cm³

Let h be the height of the water level after adding the sand. The new volume of water in the aquarium is given by:

Volume = (1/2) x 23 cm x 15 cm x h

Setting this equal to the new total volume, we can solve for h:

(1/2) x 23 cm x 15 cm x h = 2522.5 cm³

h = 2522.5 cm³ / (1/2 x 23 cm x 15 cm) = 18 cm

The nearest Whole percent, the percent increase of women students is approximately 21%.

The percent increase of women students, we need to compare the number of women students in 2005 and 2006.

In 2005, the number of women students was 123.

In 2006, the number of women students was 149.

To find the increase, we subtract the initial value (2005) from the final value (2006):

Increase = Final Value - Initial Value

Increase = 149 - 123

Increase = 26

Next, we need to calculate the percent increase. The percent increase is given by the formula:

Percent Increase = (Increase / Initial Value) * 100

Answer:

Step-by-step explanation:

This is a triangle with sides 15.2 cm, 6.6 cm, and 15.6 cm. To solve for the angles, we can use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab cos(C)

where a = 6.6 cm, b = 15.6 cm, c = 15.2 cm, and C is the angle opposite side c.

Using this formula, we can solve for the cosine of angle C:

cos(C) = (a^2 + b^2 - c^2) / 2ab

cos(C) = (6.6^2 + 15.6^2 - 15.2^2) / (2 * 6.6 * 15.6)

cos(C) = 0.748

Taking the inverse cosine of 0.748, we get:

C = 41.5 degrees

To find the other angles, we can use the Law of Sines:

a/sin(A) = b/sin(B) = c/sin(C)

Using this formula, we can solve for angle B:

sin(B) = (b/sin(C)) * sin(A)

sin(B) = (15.6/sin(41.5)) * sin(A)

sin(B) = 0.614 * sin(A)

Using the fact that sin(A) + sin(B) + sin(C) = 1, we can solve for sin(A) and sin(B):

sin(A) = (sin(C) - sin(B)) / (1 + cos(C))

sin(A) = (sin(41.5) - 0.614 * sin(A)) / (1 + cos(41.5))

Solving for sin(A), we get:

sin(A) = 0.266

Using this value of sin(A), we can solve for sin(B):

sin(B) = 0.614 * sin(A)

sin(B) = 0.157

Taking the inverse sine of these values, we get:

A = 15.4 degrees

B = 123.1 degrees

Therefore, the triangle has angles of approximately 15.4 degrees, 123.1 degrees, and 41.5 degrees.

The general equation is y=mx+b

where m is the slope and b is the y intercept.

So substitute the m and the b for the equation.

m=2, b = 5 : y = 2x+5

m=3 b = 5: y = 3x + 5

m = 5 b = 4: y = 5x + 4

The equation of the circle with radius 9 and center ( -1,-8 ) is( x + 1 )² + ( y + 8  )² = 81.

The standard form equation of a circle with center (h, k) and radius r is:

( x - h )² + ( y - k )² = r²

Given that the circle has a center of (-1, -8) and the radius is 9.

Hence; from the standard form of the equation of the circle:

Center ( h , k ) = ( -1, -8 )

h = -1

k = -8

And radius r = 9

Plug these values into the above formula and simplify.

( x - h )² + ( y - k )² = r²

( x - ( -1 ) )² + ( y - ( -8 ) )² = 9²

To find the resulting image of Triangle ABC after reflecting it across the line y=-x and rotating it 90 degrees clockwise, we can follow these steps:
1. Draw Triangle ABC and the line y=-x on a coordinate plane.
2. Reflect Triangle ABC across the line y=-x to get its image, Triangle A'B'C'.
3. Draw the image Triangle A'B'C' on the coordinate plane.
4. Rotate Triangle A'B'C' 90 degrees clockwise around the origin to get its final image.
5. Draw the final image of Triangle ABC, which is Triangle A''B''C''.
To find the coordinates of the image points, we can use the transformation rules for reflections and rotations.
First, let's find the image points after reflecting Triangle ABC across the line y=-x:
- The point A(-2, 3) is reflected to the point A'(-3, 2) by swapping the x and y coordinates and changing their signs.
- The point B(4, 1) is reflected to the point B'(-1, -4) by swapping the x and y coordinates and changing their signs.
- The point C(1, 5) is reflected to the point C'(-5, -1) by swapping the x and y coordinates and changing their signs.
Now, let's find the image points after rotating Triangle A'B'C' 90 degrees clockwise around the origin:
- To rotate a point (x, y) 90 degrees clockwise around the origin, we can use the formulas (-y, x).
- Applying this formula to each image point, we get:
 - A''(2, 3)
 - B''(1, 4)
 - C''(5, 1)
Therefore, the resulting image of Triangle ABC after reflecting it across the line y=-x and rotating it 90 degrees clockwise is Triangle A''B''C'' with vertices at (2, 3), (1, 4), and (5, 1).

We can see here that the 90% confidence interval will be: 420.2 to 585.8.

An interval of values known as a confidence interval is one that is likely to include the real value of a population parameter. A confidence interval of 95%, for instance, indicates that there is a 95% likelihood that the population parameter's real value falls inside the interval.

We will find the sample mean first:

Sample mean = sum of data points / number of data points

Sample mean = 8551 / 17 = 503

Then the standard error will be:

Standard error = population standard deviation / square root of number of data points

Standard error = 190 / √(17) = 41.7

Confidence interval = Sample mean ± 1.645 × standard error.

where 1.645 is the z-score for a 90% confidence interval.
