Answer 1
Answer:

Answer:

  • C. Dependent

Explanation:

When events are independent the probability of one does not depend on the other.

Here the probability of liking peas overall is 39%, but the probability of liking peas if you're male is 42%. That is, the probabilities are not the same, so the events are dependent.

_____

Comment on answer choices

Selections B and C are both "Dependent," so are correct in that aspect. However, the "reason" given for B has a bogus number (54%) for males liking peas. We have no idea where that number came from. C has the correct reason, so is the appropriate selection.

Given that a point of measure is 3m away from a tree, and the top of the tree is at a 60 degree angle from the ground,find the height of the tree.

Answers

So there is a right triangle.

The tree hight over the distance from the tree is equal to the tangent of the angle.

h / 3 = tan(60)

h / 3 = √(3)

h = 3√(3)

Final answer:

To find the height of the tree, we can use trigonometry and the tangent function. The height of the tree is approximately 5.2 meters.

Explanation:

To find the height of the tree, we can use trigonometry. We have a right triangle formed by the tree, the point of measure, and the ground. The distance from the point of measure to the tree is the adjacent side, and the height of the tree is the opposite side. We can use the tangent function to find the height:

tan(60°) = height/3m

height = 3m * tan(60°) = 3m * √3 ≈ 5.2m

Therefore, the height of the tree is approximately 5.2 meters.

Question 2Which collection of three side lengths will NOT form a triangle?


6 in, 10 in, 18 in


10 in, 12 in, 15 in


10 in, 15 in, 6 in


10 in, 18 in, 12 in

Answers

Side lengths with 6 in, 10 in, 18 will not form a triangle 'cause we know, that sum of shorter sides must be greater than the longer side but here it's not.

In short, Your Answer would be Option A

Hope this helps!
6 in, 10 in, 18 in
The sides need to be in between (10-6) and (10+6) or between 4 and 16. But the third side here is 18, so that cannot qualify as a side. 

Hope this helps. 

A regular hexagon is shown below. Find the value of x.
(11x + 21)°

Answers

The value of {x} for the hexagon shown is 9.

What is Hexagon?

A hexagon is a polygon with 6 equal sides. The perimeter of a hexagon is the sum of all the six lengths. The measure of the interior angle of a hexagon is 120 degrees.

Given is to find the value of {x} in the Hexagon shown below.

The measure of the internal angle of a hexagon is 120 degrees. So, we can write -

(11x + 21) = 120

11x = 120 - 21

11x = 99

x = 9

Therefore, the value of {x} for the hexagon shown is 9.

Answer:

x=9

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to .

Since an interior angle of a hexagon measures 120°, we have the equality

.

Now it is just a matter of solving for  

11x=120-21

11x=99

x=99/11

x=9

A cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones. The numbers y of cell sites from 1985 through 2011 can be modeled byy = 269573/1+985e^-0.308t where t represents the year, with t = 5 corresponding to 1985. Use the model to find the numbers of cell sites in the years 1998, 2003, and 2006.

Answers

Answer:

(a) 3178

(b) 14231

(c) 33152

Step-by-step explanation:

Given

y = (269573)/(1+985e^(-0.308t))

Solving (a): Year = 1998

1998 means t = 8 i.e. 1998 - 1990

So:

y = (269573)/(1+985e^(-0.308*8))

y = (269573)/(1+985e^(-2.464))

y = (269573)/(1+985*0.08509)

y = (269573)/(84.81365)

y = 3178 --- approximated

Solving (b): Year = 2003

2003 means t = 13 i.e. 2003 - 1990

So:

y = (269573)/(1+985e^(-0.308*13))

y = (269573)/(1+985e^(-4.004))

y = (269573)/(1+985*0.01824)

y = (269573)/(18.9664)

y = 14213 --- approximated

Solving (c): Year = 2006

2006 means t = 16 i.e. 2006 - 1990

So:

y = (269573)/(1+985e^(-0.308*16))

y = (269573)/(1+985e^(-4.928))

y = (269573)/(1+985*0.00724)

y = (269573)/(8.1314)

y = 33152 --- approximated
