valina [46]

Answer:

a is adjacent, b is opposite, c is the hypotenuse

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle XYZ we have

The side a and side b are the legs and the side c is the hypotenuse (the greater side)

The side a is the adjacent side to angle Y and is the opposite side to angle X

The side b is the opposite side to angle Y and is the adjacent side to angle X

The side c is the hypotenuse

The sum of the angles X and Y is equal to 90 degrees because are complementary angles

therefore

a is adjacent, b is opposite, c is the hypotenuse

How to work out this linear stimultaneous equations

Oduvanchick [21]

Step-by-step explanation:

extract the third equation from one of the given equation by making at most one variable with 1 as the coefficient the subject of the equation.
$x = 2 - y...........(3)$
now substitute the third equation to the other equation *Not the one you extracted the new equation from*
$y = 2 ({2 - y})^{2} + (2 -y ) - 2$
After substituting simplify
$y = 2(2 - y)(2 - y) + 2 - y - 2 \\ y = 2(4 - 2y - 2y + {y}^{2} ) + 2 - y - 2 \\ y = 2(4 - 4y + {y}^{2} ) - y \\ y = 8 - 8y + 2 {y }^{2} - y$
Therfore group the terms in the form of a general Quadratic equation.

Please help me with those questions please

Answer:

7.5

35.2

1.5

Step-by-step explanation:

1. vertical angles are equal

(2x+17)=(4x+2)

15= 2x

x= 7.5

2. adjacent angles equal 180

(2m+8)+(3m-4)= 180

5m+4= 180

5m= 176

m= 35.2

3. (30s+5)=(20s+20)

10s= 15

s=1.5

4. 4p+5p=180

9p=180

p=20

sorry that took so long. I was babysitting lol

It is desired to estimate the average total compensation of CEOs in the service industry. Data were randomly collected from 18 C

Sati [7]

Answer:

Option C

Step-by-step explanation:

Remaining part of the question

a. Yes, and I am sure of that.

b. Yes, and I am 95% confident of that.

c. No, and I am sure of that.

d. No, and I am 95% confident of that.

Solution

The compensation in the range of 95 % is ($2,190,000, $4,720,000). This indicate that there are 95% chances that a given CEO compensation will fall with in the give range.

The given salary range is $5,000,000 which does not lie in the given range. Hence, it is in the region of the graph or bell curve where there are 5% chances that the given salary range will not fall into the given salary range i,e ($2,190,000, $4,720,000)

Hence, the actual average total compensation of CEOs in the service industry can or cannot be $5,000,000

Hence, option C is correct
