Answer:
Tickets = p/2 + q/2
Step-by-step explanation:
I don't understand the options, as written.
The answer should be Tickets = p/2 + q/2
If q = 10 and p = 20, Kyle would have bought 5 tickets the week before, and 10 tickets this week.
Answer:
P(x=25)=P(z=2)=0.9972 or 99.72%
Step-by-step explanation:
Mean = 18 pounds
Standard Deviation = 3.5 pounds
x= 25
We need to find P(x=25)
First, we need to find z-score using formula: 
Finding z-score when x=25
So, we need to find P(z=2)=P(x=25)
Looking at z-score table we can find P(z=2)
P(z=2)=0.9972 or 99.72%
So, P(z=2)=0.9972 or 99.72%
Jakobe sold 150 coffee, 50 tea and 120 donuts at the coffee cart on Monday.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of coffee, y represent the amount of tea and z represent the amount of donuts, hence:
x + y + z = 320 (1)
Also:
1.5x + 2y + 0.75z = 415 (2)
And:
x = 3y (3)
From the equations:
x = 150, y= 50 and z = 120
