The coin is an illustration of probability, and the probability of getting two heads and a tail is 3/8
<h3>How to determine the probability?</h3>
The sample space of tossing a coin three times is:
S = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
On the sample space, we have:
Two heads and a tail = 3
Sample size = 8
The required probability is then calculated using:
P = 3/8
Hence, the probability of getting two heads and a tail is 3/8

Answer:
Option C: 41
Step-by-step explanation:
<ABD+<CBD=90
<ABD=8x+1
<CBD=6x+5
(8x+1)+(6x+5)=90
Combine like terms
(8x+6x)+(1+5)=90
14x+6=90
14x=90-6
14x=84
divide both sides by 14
x=6
Now we plug that value into <DBC = 6x+5
6(6)+5=
36+5
41
Multiply each side of the equation by 4/3 .
Answer:
(x - 6) (x + 6)
Step-by-step explanation:
Given the quadratic equation , we can rewrite it as the product of two binomials using the formula: . Therefore, the two binomials as factor of are (x - 6) (x + 6).
To verify whether this answer is correct, you can use the FOIL method:
(x - 6) (x + 6) = + 6x - 6x - 36 = .
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.
Then, using the circle area formula, the area of the 1/9 circle would be:
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57
