The value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$ . Option D is correct.

<h3>What are the trigonometric ratios?</h3>

Trigonometric ratios are the ratio of sides of a right angled triangle. There are 6 types of trigonometric ratios: sin, cos, tan, cosec, sec, and cot.

Sine trigonometric ratio is the ratio of perpendicular (side opposite to the angle) to the hypotenuse.

In the given figure, the side opposite to the angle $\beta$ is AC = 4 and the hypotenuse is AB = 5.

So, the sine ratio will be equal to,

$\sin \beta=\dfrac{4}{5}$

Therefore, the value of $\sin \beta$ in the given triangle ABC is $\dfrac{4}{5}$ . Option D is correct.

Answer:

the chance that the population mean will either be less than $1,500 or above $2,100 is 10%

Step-by-step explanation:

We are 90% confident that the true population mean willl be between $1,500 and $2,100

This means that there is a 90% probability that the true population mean will be between $1,500 and $2,100.

So 100-90 = 10% probability that it is outside of this interval, that is, either be less than $1,500 or above $2,100.

So the correct answer is:

the chance that the population mean will either be less than $1,500 or above $2,100 is 10%

OMG can someone please help me solve this problem

klasskru [66]

The correct answer is A.) { - 0.79 ; 1.08 }, because
 For ax^2 + bx + c = 0, the value of x is given by: ;
a = - 7 ; b = 2 ; c = 6 ;
b^2 - 4ac = 4 + 168 = 172 ; $\sqrt{172}$ ≈ 13.11 ;
x 1 = ( - 2 + 13.11 ) / (- 14) = 11.11 / ( - 14 ) ≈ -0.79 ;
x = 2 = ( - 2 - 13.11 ) / ( - 14 ) = (-15.11) / (- 14 ) ≈ 1.08 ;

Ruby red paint costs $0.50 per square inch. A ball is painted ruby red and costs $100.00 to paint. What is the diameter of the b

8090 [49]

The diameter can be obtained by the formula A = pi*r^2

First, multiply 0.50 * 100 to obtain the area of the ball, then simplify and solve for the radius. Doubling the radius would yield the diameter. This is shown below:

Area of the ball = 0.50 * 100 = 50 in^2
A = pi*r^2
50 = (3.14)*r^2
r = 3.99 = approx. 4
diameter = 2r
Diameter = 8 inches.

Among the choices, the correct answer is C. 8.0 in.

A cylinder has a volume of 390 cm³. If a cone has the same dimensions as the cylinder then what is the volume of the cone.

dangina [55]

Answer: The volume of the cone is 130 cubic centimeters.

Step-by-step explanation:

We know that to find the volume of a cylinder you will use the formula

V= $\pi$ $r^{2} *h$ Where r is the radius and h is the height.

And to find the volume of a cone you will use the formula

V= $\pi$ $r^{2}$ *h /3

So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.

V = 390/3

V = 130 cm^3
