Answer:
9:4:6
Step-by-step explanation:
- Raffle =£450.00
- Quiz +Refreshment=19 at £7 each+£67 =19 X £7+£67 =£ 200
- Membership fees =30 at £10 each=30X£10=£300
Therefore, the ratio of the income:
Raffle : Quiz : Membership fees =450:200:300
Dividing all through by 50
Ratio=9:4:6
Answer:
p < -9
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
4p - 1 < 3p - 10
<u>Step 2: Solve for </u><em><u>p</u></em>
- Subtract 3p on both sides: p - 1 < -10
- Add 1 on both sides: p < -9
Here we see that any number <em>p</em> less than -9 would work as a solution to the inequality.

Step-by-step explanation:
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
