2 answers:
Answer:
Step-by-step explanation:
Givens:
- The number of kilograms of salt is
.
- The number of kilograms of pepper is
- Noor wants to spend less than $20, that means he's gonna spend $18, $17, $16, ...
- Salt per kg costs $1.50.
- Pepper per kg costs $2.50
The cost of the salt would be expressed
The cost per kilogram of pepper would be
The whole problem is modelled by this inequality
Basically, this expression states that Noow is not gonna pay $20 or more, and the price of salt per kg is $1.50 and $2.50 per kg of pepper.

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms
Balls height
To find all values of t for which the ball's height is 3 meters
We plug in 3 for h and solve for t
Solve for t
Solve using quadratic formula
After simplifying this,
= 0.11898
= 1.68102
the values of t for which the ball's height is 3 meters= 0.12 sec , 1.68 sec
Answer:
4 possible outcomes
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
In this problem
<em>The probability of choose a blue card is </em>
substitute
<em>The probability of choose a green card is </em>
substitute
<em>The probability of choose a red card is </em>
substitute
<em>The probability of choose a yellow card is </em>
substitute
The sum of the probabilities of the 4 possible outcomes is equal to
