<h2>
C. { HH, HT , TH, TT}</h2>
Step-by-step explanation:
Sample Space of any event E is the set of all possible outcomes whenever that event takes place.
Here, event E : Tossing 2 coins
Now, as we know, when an unbiased coin is tossed,
The total outcomes = {Head, Tail}
So, when two coins are flipped, the total outcomes are 2 x 2 = 4.
Sample space = { Head Head, Head Tail, Tail Head, Tail Tail}
or, S = { HH, HT , TH, TT}
The problem is using a right triangle, it means we can use the Pythagorean theorem in solving the problem. We have two possible measurements for the third side.
First length, when the third side is the hypotenuse:
x ² = 15² + 12²
x = 19.21
Second possible length, when the third leg is either an adjacent or base side:
15² = x² + 12²
x = 9
Therefore, the difference between the two possible answers are shown below:
Difference = 19.21 - 9 = 10.21
Answer:
a. Yes
b. Yes
c. Yes
d. No
Step-by-step explanation:
a. Because -10x+4x=6x
b. 2(12-3x)=2*12-2*3x=24-6x
c. 24 and -6x just switched places.
d. 24x-6x=18x not 24-6x
Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
180*60%=180*60/100=10800/100=108
180+108=288
So the total population os school is 288 students!
