13. For question 13). 4/10, 7/12, 1/2
The formula for the area is A=p*q/2
so now we put in the numbers so the formula is now A=14*8/2
14* 8 is 112
we now divide 112 by two giving us 56
thus 56 is the answer
hoped i helped!
Answer:
The correct answer is C. More than 1 kg
Step-by-step explanation:
since 3/2 is already greater than 1 and we are adding, the result must be greater than one.
Answer:
x² + 6x - 5x – 30=(x-5)(x+6)
Step-by-step explanation:
x² + 6x - 5x – 30=x²+x-30
delta=1-4(-30)=1+120=121=11²
Sqrt(delta)=11
The roots are:
x1,2=(-1 +- 11)/2
Thus we get
x1=(-1+11)/2=10/2=5
x2=(-1-11)/2=-12/2=-6
Finally:
x² + 6x - 5x – 30=(x-5)(x+6)
Answer:
X is a discrete Random variable where X is the number of races Jockey can win.
Step-by-step explanation:
To find - A jockey will ride horses in 10 different races at a race track today.
The number of races that the jockey will win is what type of random variable ?
Proof -
Given that,
A jockey will ride horses in 10 different races at a race track today.
Let us assume that,
X is the number of races Jockey can win
So,
X can take value 0, 1, 2, 3, ......10
As,
It can take countable finite values
So,
X is a discrete Random variable
∴ we get
X is a discrete Random variable where X is the number of races Jockey can win.
