Answer:
x is the 9 multiple = 9x
Step-by-step explanation:
- Let x is the numbers of flour tortillas packages
- Let y is the numbers of corn tortillas packages
=> the total packages : x + y
Given that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16, it means:
<=>
=
<=> 16y = 7x+7y
<=> 9y = 7x
<=> x = 
since both x and y are integers y is in the form of 7k where k∈N so
x = 9k
So x is the 9 multiple.
Hope it will find you well.
C) The number of questions answered correctly on the exam.
In vertex form the value of the vertex is easily identified in the equation. I’m standard form the value of the x intercepts are evident.
Answer:
12x-7y+3z
Step-by-step explanation:
The expected value of the winnings from the game is $4
<h3>How to determine the expected value?</h3>
The payout probability distribution is given as:
Payout ($) 2 4 6 8 10
Probability 0.5 0.2 0.15 0.1 0.05
The expected value is then calculated as:

This gives
E(x) = 2 * 0.5 + 4 * 0.2 + 6 * 0.15 + 8 * 0.1 + 10 * 0.05
Evaluate the expression
E(x) = 4
Hence, the expected value of the winnings from the game is $4
