Answer:
4+5+6+1=16 divided by 4 equals 4 i divided it by 4 because there are 4 pairs of numbers so the anser is 4
Step-by-step explanation:
Hi, Siyasi2 ! Let x = the number of hot dogs, y = the number of chips, and z = the number of drinks. Then we know:
5x + 4y + 5z = 15.75
x = y + 0.75
z = 2x - 1
Let's substitute the 3rd equation into the first one.
5x + 4y + 5(2x - 1) = 15.75
5x + 4y+ 10x - 5 = 15.75
15x + 4y = 20.75
Now, let's re-write the 2nd equation as x - y = 0.75
We now have a system of two equations with two unknowns.
15x + 4y = 20.75
x - y = 0.75
To solve this, we can multiply the bottom equation by 4 and add.
15x + 4y = 20.75
+ 4(x - y = 0.75)
19x = 23.75
or x = 1.25
If x = 1.25, then using the one of the equations above, we can solve for y.
x - y = 1.25 - y = 0.75
.50 = y
Since z = 2x - 1, then z = 2(1.25) - 1 = 2.5 - 1 = 1.50
So, a hot dog is $1.25, chips are 50 cents, and a soft drink is $1.50. Please let me know if you have any questions.
Answer:
Ok, let's calculate the number of possible outcomes:
First, let's see the events and the number of outcomes in each event:
Drawing a card --- 4 outcomes
Rolling a number cube ---- 6 outcomes.
The total number of outcomes will be equal to the product between the number of outcomes in each individual event, this is:
C = 4*6 = 24.
Now, suppose that you have a restriction like:
"What is the probability that you have an odd number in the number cube?"
Ok, let's do the same:
Drawing a card ---- 4 outcomes (the restriction does not affect this event)
Rolling a number cube ---- 3 outcomes (because there are only 3 odd numbers)
The number of combinations is:
C' = 4*3 = 12.
Then the probability will be the quotient between the number of outcomes that meet the condition and the total number of outcomes:
P = C'/C = 12/24 = 0.5
