Answer:

x = 15 $\sqrt{3}$ , y = 15

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and the exact values

sin60° = $\frac{\sqrt{3} }{2}$ , cos60° = $\frac{1}{2}$ , then

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{30}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2x = 30 $\sqrt{3}$ ( divide both sides by 2 )

x = 15 $\sqrt{3}$

---------------------------------------------------------

cos60° = $\frac{adjacent}{hypotenuse}$ = $\frac{y}{30}$ = $\frac{1}{2}$ ( cross- multiply )

2y = 30 ( divide both sides by 2 )

y = 15

Exhibit 10-7 In order to estimate the difference between the average hourly wages of employees of two branches of a department s

Leokris [45]

Answer:

$E(x)=1$

Step-by-step explanation:

From the question we are told that:

Sample mean 1 $\=x_1=$9$

Sample mean 1 $\=x_2=$8$

Sample standard deviation 1 $\sigma_1 = $2$

Sample standard deviation 1 $\sigma_2 = $1$

Generally the equation for Point estimate is mathematically given by

$E(x)=\=x_1-\=x_2$

$E(x)=9-8$

$E(x)=1$

Hi can you help me please?)

<em>To solve for a variable, you just need to isolate the variable to one side.</em>

For this, just divide both sides by r and <u>your answer will be $\frac{d}{r}=t$ </u>

For this, divide both sides by nR and <u>your answer will be $\frac{PV}{nR}=T$ </u>

Firstly, multiply both sides by T: $AT=FV-OV$

Next, subtract FV on both sides of the equation: $AT-FV=-OV$

Lastly, multiply both sides by -1, and <u>your answer will be $-AT+FV=OV$ </u>

Firstly, multiply both sides by 1000: $1000C=Wtc$

Lastly, divide both sides by tc and <u>your answer will be $\frac{1000C}{tc}=W$ </u>

1.The amount of space around an object.

Mekhanik [1.2K]

Answer:

Mass
Surface area
Volume

Step-by-step explanation:

The size of a surface. The amount of space inside the boundary of a flat (2-dimensional) object such as a triangle or circle, or surface of a solid (3-dimensional) object

A property of a physical body and a measure of its resistance to acceleration when a net force is applied.

<u>Surface </u>

The area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

<u>Volume </u>

The Measure of the amount of space that a substance or an object takes up.
