Answer: 10.67 pounds
Step-by-step explanation:
Let her adult weight be represented by x.
Luna weighs 8 pounds which is about 75 % of her adult weight. This can then be formed into an equation as:
75% of x = 8
75/100 × x = 8
0.75 × x = 8
0.75x = 8
x = 8/0.75
x = 10.67
Her adult weight is 10.67 pounds
Answer:
The expectation the instructor to send each day
E(X) = 3.65
Step-by-step explanation:
Given data x : 0 1 2 3 4 5
P(X=x) : 0.05 0.05 0.1 0.1 0.4 0.3
The given data satisfy the two conditions
I) Given all probabilities are p₁(x) ≥0
ii) sum of all probabilities is equal to one
0.05 + 0.05 + 0.1 + 0.1 + 0.4 +0.3 =1
Therefore given data is discrete probability distribution
<u>Expectation</u> :-
suppose a random variable X assumes the values with respective probabilities , then the Expectation or Expected value of X , denoted by E(X) = ∑pi xi
on simplification, we get
E(X) = 3.65
Answer:
6cm
Explanation:
You already know that part of the line is 4cm. It can’t be 3cm because that would be too long. You see that because the 3cm obviously is too big. Then you see how it around half the size of the 4cm, and realize that the line is 2cm. So then you add 2+4=6
