For this entry, you are a math expert at a local school. Explain to a group of students how independent and dependent events are

GaryK [48]

Answer:

hope this helps!

Step-by-step explanation:

Sample response: The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

Solve: -3= 12x-5(2x-7)

leonid [27]

Answer:

x = -19

Step-by-step explanation:

-3= 12x-5(2x-7)

Distribute

-3= 12x-10x+35

Combine like terms

-3 = 2x +35

Subtract 35 from each side

-3-35 = 2x+35-35

-38 = 2x

Divide each side by 2

-38/2 = 2x/2

-19 =x

Help with this question please! Give explanation! Big points

BigorU [14]

Answer:

$y = 2$

Step-by-step explanation:

This answer is easily found using the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

where A and B are the legs, and C is the hypotenuse of the triangle.

${(16)}^{2} + {(6y)}^{2} = {(10y)}^{2} \\ 256 + 36{y}^{2} = 100 {y}^{2} \\ 256 = 64 {y}^{2} \\ \sqrt{256} = \sqrt{64 {y}^{2}} \\ 16 = 8y \\ y = 2$

Find the value of cos x° + sin yº

MA_775_DIABLO [31]

Answer:

1.84

Step-by-step explanation:

The given arc is a part of a unit circle centered at origin.

The x-coordinate on the unit circle represent the cosine value and y-coordinate on the unit circle represent sine value.

So, for angle equal to $x$ °, the x coordinate represents $cos (x)$ °.

So, $cos x$ ° = 0.86

Similarly, the y-coordinate of angle y represent $\sin y$ °.

So, $\sin y$ ° = 0.98

Therefore, the value of $cos (x)$ ° + $\sin y$ ° = 0.86 + 0.98 = 1.84.

Will give 25 points if someone can answer this page

Studentka2010 [4]

Answer:

Domain = {1,2,3,4,5,6} and Range = {42,49,56,63,70,77The given function is :

y = 7x + 35

Where

x is no of members

y is the monthly cost

Your group has enough money for up to six members to joim fitness club. It means domain (the set of input values) are:

Domain = {1,2,3,4,5,6}

Put x = 1 to 6 one by one,

y = 7(1) + 35 = 42

y = 7(2) + 35 = 49

y = 7(3) + 35 = 56

y = 7(4) + 35 = 63

y= 7(5) + 35 = 70

y = 7(6) + 35 = 77

Range = {42,49,56,63,70,77}
