Given:
The table and the relative frequency histogram show the distribution of the number of tails and three coins are tossed.
To find:
The probability 
.
Solution:
In the given table T represents the number of tails.
From the given table it is clear that the value of probability is 
and 
. So,
Therefore, the probability is equal to .
Answer:
x = 11.5
Step-by-step explanation:
For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.
Answer:
4. 3
Answer:
-1
Step-by-step explanation:
So you are asked to find 3f(1)-4g(-2).
In order to find this you must first find f(1) and g(-2).
So f(1) means what is the value of the expression 3x-2 for when x=1.
f(1)=3(1)-2
f(1)=3-2
f(1)=1
And g(-2) mean what is the value of the expression 5-x^2 for when x=-2.
g(-2)=5-(-2)^2
g(-2)=5-(4)
g(-2)=5-4
g(-2)=1
So both of those function values were 1.
Our problem of 3f(1)-4g(-2) becomes 3(1)-4(1)=3-4=-1.
Answer: 39
Step-by-step explanation: Using the hypotenuse formula which is C=square root of a square plus b squared. Plug it in as such, square root of 36 sqaured plus 15 squared, and you'll get your hypotenuse. Hope this helps!
