In the given rectangle,

The value of x is 3

The value of NP is 18

From the question, we are to determine the value of x in the given diagram.

The diagram shows a rectangle with its diagonals.

Since the diagonals of a rectangle bisect each other, we can write that

2x + 3 = 12 - x

Solve the equation for x

2x + 3 = 12 - x

Add x to both sides of the equation

2x + x + 3 = 12 - x + x

3x + 3 = 12

Subtract 3 from both sides of the equation

3x + 3 - 3 = 12 - 3

3x = 9

Divide both sides of the equation of by 3

3x / 3 = 9 / 3

x = 3

Thus,

The value of x is 3

To determine the value of NP

NP = 2(12 - x)

Substitute the value of x

NP = 2(12 - 3)

NP = 2(9)

NP = 18

Hence, the value of NP is 18

The measure of the obtuse angle with vertex P is 30 degrees.

We have,

If there is an acute angle with vertex Q measuring 60 degrees, then there must be a corresponding obtuse angle with vertex P that shares the same side as angle Q.

Let's call the measure of this obtuse angle x.

By the angle sum property of triangles, the sum of the measures of the three angles in any triangle is always 180 degrees.

Therefore, we can write the equation:

60 degrees + 90 degrees + x = 180 degrees

Simplifying this equation, we get:

x = 180 degrees - 60 degrees - 90 degrees = 30 degrees

Therefore,

The measure of the obtuse angle with vertex P is 30 degrees.

Answer:

x = 5

y = 5√2

Step-by-step explanation:

In a 45-45-90 degree right triangle, the two legs form the right angle, and the hypotenuse is opposite the right angle.

The side lengths of a 45-45-90 right triangle are in the ratio

1 : 1 : √2

The legs are congruent, so if one leg has length 5, the other leg also has length 5.

The hypotenuse is √2 times the length of the legs.

x = 5

y = 5√2

Answer: 2,556 seats

Step-by-step explanation

18 x 142 =2,556 seats

Answer:

To find 40% of a number, you can multiply the number by 0.4 or divide it by 2.5.

Using this method, we get:

40% of 100 is 40 (100 x 0.4 or 100 ÷ 2.5)

40% of 110 is 44 (110 x 0.4 or 110 ÷ 2.5)

40% of 140 is 56 (140 x 0.4 or 140 ÷ 2.5)

40% of 120 is 48 (120 x 0.4 or 120 ÷ 2.5)

Therefore, 40% of 100 is 40, 40% of 110 is 44, 40% of 140 is 56, and 40% of 120 is 48.

The number that take (a) both PE is 6 girls (b) Gymnastic but not acrobat is 7 girls (c)  At least one PE is 18 girls

How to determine the numbers?

Recall that Set theory is a branch of mathematical logic that studies sets, which can be informally described as collections of objects.

From the given parameters,

(a)  The number that play both PE is given as

13 - x + x + 17 - x + 1 = 25

Solving the equation to get the value of x

13+17-x = 25

⇒ 31 -x =25

Collecting like terms we have

-x = 25 - 31

- x = -6

Dividing by a minus we have

x = 6

This means that 5 girls play both PE

(b)  Number that play gymnastic but not acrobat is given as

Gymnastic only that is

13 - x

13 - 6 = 7 girls

(c)  Number that play at least one game is calculated thus:

n(G) ∪ n(A)

That is (13 - x )  + (17 - x)

= 13-6 + 17 -6

7 + 11 = 18 girls

The equations of the circles in standard form, obtained from the coordinates of the center and the points on the circle are;

5) (x + 16)² + (y + 16)² = 3²

6) (x - 15)² + (y + 7)² = 8

7) (x + 6)² + (y + 2)² = 6²

8) (x + 9)² + (y + 3)² = 89

The standard form of the equation of a circle is; (x - h)² + (y - h)² = r²

Where;

(h, k) = The coordinates of the center of the circle

5) The center of the circle is (-16, -16)

The coordinates of a point on the circle is (-13, -16)

Therefore; r² = (-13 - (-16))² = 3²

The equation of the circle in standard form is therefore;

(x - (-16))² + (y - (-16))² = 3²

(x + 16)² + (y + 16)² = 3²

6) The coordinates of the center of the circle = (15, -7)

The coordinate of a point on the circle = (17, -5)

r² = (17 - 15)² + (-5 - (-7))² = 8

The equation is; (x - 15)² + (x - (-7))² = 8

(x - 15)² + (x + 7)² = 8

7) The coordinates of the center = (-6, -2)

The coordinate of a point on the circle = (-12, -2)

The square of the radius is therefore; r² = (-6 - (-12))² = 6²

(x - (-6))² + (y - (-2))² = 6²

(x + 6)² + (y + 2)² = 6²

8) The coordinates of the center is; (-9, -3)

The point on the circle is; (-1, -8)

The square of the radius is; r² = (-1 - (-9))² + (-8 - (-3))² = 89

The equation of the circle is therefore; (x - (-9))² + (y - (-3))² = 89

The 90% confidence that the proportion of yellow peas is between 23.5% and 29.5%

and, 25% estimate falls within the 90% confidence limits.

We have,

Green peas= 445

Yellow peas= 161

So, Total peas:

= 445 + 161

= 606.

Now, the Proportion of yellow

= 161/606

= 0.265676

= 26.56%

Now, p= 0. 265 and q= 1-0.265= 0.735

So, np = 606 (0.265)= 160.59

nq = 606(0.735) = 445.41

As, both results are ≥ 5 and the sample can be approximated by a normal distribution.

For 90% confidence, z = 1.645.

Now, the margin error

= 1.645 √ (0.265)(0.735) / 606

= 1.645 / 0.0179

= 0.0294

Now, The confidence limits are the point estimate ± the margin of error. =

The probability that Brent draws mismatched socks is 32/153.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Since Brent is drawing two socks without replacement, there are 18 choices for the first sock and 17 choices for the second sock.

Therefore, there are 18 x 17 = 306 possible ways Brent could draw two socks.

For Brent to have mismatched socks, he needs to draw a white sock first and a black sock second, or a black sock first and a white sock second.

Let's consider the first case.

There are 16 white socks and 2 black socks, so there are 16 x 2 = 32 ways Brent could draw a white sock first and a black sock second.

For the second case, there are 2 black socks and 16 white socks, so there are 2 x 16 = 32 ways Brent could draw a black sock first and a white sock second.

Therefore, the probability of Brent drawing mismatched socks is:

= (32 + 32) / 306

= 64 / 306

= 32 / 153

Thus, the probability that Brent draws mismatched socks is 32/153.

To perform the similarity transformation, we first apply the translation by subtracting 3 from the x-coordinates and subtracting 1 from the y-coordinates:

F' = (2-3, 2-1) = (-1, 1)

G' = (2-3, 4-1) = (-1, 3)

H' = (4-3, 4-1) = (1, 3)

Next, we apply the dilation with a scale factor of 2 by multiplying each coordinate by 2:

Integrating the second derivative, the first derivative of the function is given as follows:

f'(x) = x² - 6cos(x) + K.

When x = 0, y' = 2, hence the constant K is given as follows:
