Answer:
2
Step-by-step explanation:
let n=4q+3
then 2n =8q+6
=4(2q+1)+2
Answer:
Step-by-step explanation:
In the tossing of a fair coin, there are equal probabilities of getting a HEAD and getting a TAIL.
Total probability is always 1 and a coin has 2 faces - Head & Tail.
The probability of getting a Head is 1/2 = 0.5
The probability of getting a Tail is 1/2 = 0.5
E1 is the event that TAIL comes up when the coin is tossed the first time
E2 is the event that HEAD comes up when the coin is tossed the second time
The probability value for EVENT 1 is 0.5
The probability value for EVENT 2 is 0.5
Answer:
x = 75
Step-by-step explanation:
Triangle BDH
The angle must add to 180 degrees
36+ 39 + DHB = 180
75 + DHB = 180
DBH = 180-75
DHB = 105
DBH + x = 180 since it is a straight line
105+ x = 180
x = 75
Trig problem here. We have 2 right triangles, the one on the left and on the right. They share one side. To find the length of this side, look at the left triangle. The hypotenuse is 44 and theta is 25, and since cos(theta)=adjacent/hypotenuse, cos(25)=adjacent/44 therefore the sidelength is 44cos(25). We are looking for x and now have an angle and a side for the righthand side right triangle so because tan(theta)=opposite/adjacent, tan(34)=opposite/(44cos(25)) therefore the opposite side is 44*cos(25)*tan(34)
