Answer:
Step-by-step explanation:
98*x = 101.92
x = 101.92/98 = 1.04
The % increase is 1.04%
Answer:
2/9
Step-by-step explanation:
given that a set of 10 cards consists of 5 red cards and 5 black cards. The cards are shuffled thoroughly and you turn cards over, one at a time, beginning with the top card.
Let X be the number of cards you turn over until you observe the first red card.
X can take values as 1,2,3,4,5 or 6.
No other possibility because at the worst 6th card has to be red
P(X>2) = 1-(P(X=1)+P(x=2))
P(X=1) = Prob for I card to be red =
P(x=2) Prob for I card black and second red =
Answer: The width of the field = 120
Step-by-step explanation: This question can be solved by first opening of the bracket, then relating the equation to quadratic general equation and finally solve for domain of X by using quadratic formula.

Answer:
1/8 square unit.
Step-by-step explanation:
Remark
The piece of information that is missing is is the middle line parallel to 2 of the sides. You have to assume it is, otherwise the question is impossible to do.
Givens
The height of the red triangle is 1/2 the top or bottom white triangle. That's because the diagonals and the horizontal line all meet in the middle.
The base of the red triangle is equal to 1/2 the length of the base.
Formula
Area red = 1/2 b * h
Solution
b = 1/2
h = 1/2
Area = 1/2 * 1/2 * 1/2
Area = 1/8
