Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1
Answer:
E(X) = 17.4
Step-by-step explanation:
We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:
E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.
In this way the expexted value is
E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4

Answer:
5.7 in^2
Step-by-step explanation:
First find missing leg measurement a
a^2= c^2- b^2
a^2= 36-4
a^2= 32
a= 5.7
find area of triangle
a= AB/2
a= (2*5.7)/2
a= 5.7 in^2
Answer:
yes, fractions are like 1/2 or 3/6 but a whole number is not a part or a fraction such as 124.
