What is the estimated probability that at least one of the next four fish Roxanne catches will be a trout?

A. 35%
B. 60%
C. 70%
D. 65%​

Answer:

480 in²

Step-by-step explanation:

The Pythagorean Theorem is a²+b²=c², where "a" and "b" are side lengths of a right triangle, and c is the hypotenuse of the right triangle. We are given a side length of 30 inches and a hypotenuse of 34 inches, which will be "a" and "c" respectively. Therefore, we can solve for b, the missing side length:

a²+b²=c²

30²+b²=34²

900+b²=1156

b²=256

b=16

Therefore, the missing side length is 16 inches, making the area of the triangle A=bh=(30)(16)=480 in².

Answer:

The area is 240

=========================================================

Explanation:

The sine ratio involves the opposite over hypotenuse.

With respect to reference angle J, the opposite leg is the one furthest from the angle. So the opposite side is KL = 4. The hypotenuse is always the longest side, always opposite the 90 degree angle, so LJ = 8 is the hypotenuse.

sin(angle) = opposite/hypotenuse

sin(J) = KL/LJ

sin(J) = 4/8

sin(J) = 0.5

Answer:

7

Step-by-step explanation:

To find the maximum number of turning points of any polynomial function, subtract one from the degree.

Since the degree is 8, subtract 1 from this:

8 - 1

= 7

So, the maximum number of turning points is 7.

As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.

Assumption : Let us assume the length as "l" and width as "b". So,

[tex] \twoheadrightarrow \quad\sf{ Length =2(Width)-5} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.

[tex]\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(2b-5+b)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(3b-5)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 6b - 10} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50+10= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{60= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{\cancel{\dfrac{60}{6}}=b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{10\; m = Width }} \\[/tex]

Now, finding the length. According to the question,

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=2(10)-5\; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=20-5\; m} [/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{15\; m = Length }} \\[/tex]

Therefore, length and breadth of the rectangle is 15 m and 10 m.

Answer:

It is not complicated to derive the formula of the surface area of a square pyramid.

Start with a square pyramid as shown below and call the length of the base s and the height of one triangle l



l is the slant height. It is not for no reason this height is called slant height!

The word slant refers also to something that is oblique or bent, or something that is not vertical or straight up. Basically, anything that is not horizontal or vertical!

The area of the square is s2

The area of one triangle is (s × l)/2

Since there are 4 triangles, the area is 4 × (s × l)/2 = 2 × s × l

Therefore, the surface area, call it SA is:

SA = s2  +  2 × s × l :

Example #1:

Find the surface area of a square pyramid with a base length of 5 cm, and a slant height of 10 cm

SA = s2  +  2 × s × l

SA = 52  +  2 × 5 × 10

SA = 25  +  100

SA = 125 cm2

(I am not 100% sure though, so if I am wrong, someone please mention it!)

The function f(x) . g(x) is a composite function, and the value of f(x) . g(x) is (x- 2)/(x + 6)

A composite function is a function formed by combining multiple independent functions

The functions f(x) and g(x) are given as:

[tex]f(x) = \frac{x + 12}{x^2 + 4x- 12}[/tex]

[tex]g(x) = \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]

The composite function f(x) . g(x) is calculated using:

[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4x^2 - 16x+ 16}{4x+ 48}[/tex]

Expand the functions

[tex]f(x) \cdot g(x) =\frac{x + 12}{x^2 + 4x- 12} * \frac{4(x^2 - 4x+ 4)}{4(x+ 12)}[/tex]

Cancel out the common factors

[tex]f(x) \cdot g(x) =\frac{1}{x^2 + 4x- 12} * \frac{x^2 - 4x+ 4}{1}[/tex]

Further, expand

[tex]f(x) \cdot g(x) =\frac{1}{(x -2)(x + 6)} * \frac{(x - 2)(x - 2)}{1}[/tex]

Cancel the common factors

[tex]f(x) \cdot g(x) =\frac{x- 2}{x + 6}[/tex]

Hence, the value of f(x) . g(x) is (x- 2)/(x + 6)

Answer: 37 donuts

Step-by-step explanation:

coffee for 2,

donuts for 1.5

c = coffee

d = donuts

lets make an equation

c*2 + (80-c)*1.5 = 141.5

from this we get:

c= 43.

if c = 43, then d is 80-43 = 37.

they sold 43 coffees, and 37 donuts.

Answer: A Diameter x pi= circumference

Step-by-step explanation:

The circumference of a circle is given as:

= 2πr

where,

π = pi = 3.14

r = radius

Note that diameter = 2 × radius.

Therefore, circumference = 2πr = πd

Therefore, circumference will be pi multiplied by diameter. The correct option is A.

Step-by-step explanation:

Answer:

92.99

Step-by-step explanation:

Mean, μ = 122.6

Standard deviation, σ = 18

Recall :

Z = (x - μ) / σ

x = score

The Zscore for the lower 5% = 0.05

Using, invnorm(0.05) = - 1.645

Put Z = - 1.645

-1.645 = (x - 122.6) / 18

-1.645 * 18 = x - 122.6

-29.61 = x - 122.6

-29.61 + 122.6 = x

x = 92.99

As triangle is right angled, we can possibly use the Pythagoras theroam.

By pythgoras theoram;

= H² = B² + P²

= 10² = x² + x²

= 10² = x⁴

=⁴√ 10² = x

= 10²×¼ = x

= 10½ = x

= √10 = x

= 3.16 = x

So the value of x is 3.16 cm

(Hypotenuse)² = (Base)²+ (Perpendicular)²

Taking, Hypotenuse As H

Base As B

Perpendicular As P

_________________________

H= 10cm

B= x cm

P= x cm

__________

H²= B²+P²

10²= x²+x²

=> 100= 2x²

=> √100= 2x

=> 10=2x

=> x=10/2

=> x= 5
