Suppose s varies directly with t. When t27, s=3. What is s when t=632
2 answers:
Answer:
G
Step-by-step explanation:
Given that s varies directly with t then the equation relating them is
s = kt ← k is the constant of variation
To find k use the condition when t = 27, s = 3 , then
3 = 27k ( divide both sides by 27 )
= k, that is
k =
s = t ← equation of variation
When t = 63, then
s = × 63 = 7 → G

b) $2.33 per cupcake
c) $2.58 per cupcake
Step-by-step explanation:
We are given the following in the question:
We have to calculate the unit price of the cupcakes.
Unit price =
12 cupcakes for $29
Unit price =
24 cupcakes for $56
Unit price =
50 cupcakes for $129
Unit price =
probability that a randomly chosen college student either has a job or lives on campus.
What is probability?
- Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true.
- The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
To find the probability that a randomly chosen college student either has a job or lives on campus:
Given: 85% of college students have a job, 54% live on campus, and 42% have a job and live on campus.
So, out of 100 students, 42 students either has a job or live on campus.
43 college students have a job and 12 live on campus.
So, 43 + 42 + 12 = 85 + 54 - 42
85 + 12 = 139 - 42
97 = 97
Therefore, probability that a randomly chosen college student either has a job or lives on campus.
