The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.

<h3>How to determine the fair game?</h3>

The number of sections in the spinner is given as:

n = 20

There are 10 numbers greater than 10 i.e. 11 to 2.

So, the probability that a number greater than 10 is spun is:

P = 10/20

P = 0.5

The probability that a number that is not greater than 10 is spun is calculated using the following complement rule

q = 1 - p

This gives

q = 1 - 0.5

Evaluate

q = 0.5

Notice that both probabilities are the equal

Hence, the spinner game that is fair is (b) If you spin a number greater than 10, you win.

Question 1

cos(C) = adj/hyp
cos(C) = BC/AC
cos(C) = 15/17

Answer: Choice C) 15/17

=============================================

Question 2

sin(E) = opp/hyp
sin(E) = FD/DE
sin(E) = 24/25

So angle E is the answer

=============================================

Question 3

AC is the adjacent side to the given angle A = 33 degrees
AB = 14 is the hypotenuse

cos(angle) = adjacent/hypotenuse
cos(33) = x/14
14*cos(33) = x
x = 14*cos(33)
x = 11.741
x = 11.7

Answer: 11.7

=============================================

Question 4

x = length of board

cos(angle) = adj/hyp
cos(55) = 6/x
x*cos(55) = 6
x = 6/cos(55)
x = 10.46068
x = 10.5

Answer: 10.5

=============================================

Question 5

112 is the adjacent side to the given angle 62 degrees
x = height of building, which is the opposite leg

tan(angle) = opp/adj
tan(62) = x/112
112*tan(62) = x
x = 112*tan(62)
x = 210.641364
x = 210.6

Answer: 210.6

Zina [86]

Answer:

When I squared the binomials, they became quadratic trinomials.

(Not sure if this is the kind of answer you want, sorry if it's not!)

(x-3)² = x² - 6x + 9

(x+2)² = x² + 4x + 4

(x-4)² = x² - 8x + 16

(x+5)² = x² + 10x + 25

Anyone knows what’s is the answer for 5 ?
Andreas93 [3]

Answer:

f(x) = |x - 4| + 3


Step-by-step explanation:

Identify (from the graph) the coordinates of the vertex:  (4, 3).  That +4 tells us that the vertex of the basic function y = |x| has been translated 4 units to the right; that +3 tells us that the vertex has also been translated 3 units up.  Consider y = |x-a| + b.  Here, b = +3 and a=+4.  Thus, the correct function is f(x) = |x - 4| + 3.

If the radius of a circle is multiplied by 3 what happens to the area of a circle
mote1985 [20]
Area equals pi multiplied by (r squared) 
Therefore; 
if the Radius is multiplied by 3 
Area = pi multiplied by (r*3)^2 
Area = pi multiplied by 9 r squared 
Thus; 
multiplying the radius by 3 increases the area by 3 squared or 9 
--- 
==> The area increases by a factor of 9 <==
