Answer:
g > 2t , 15 t + 9g >500 are the inequalities which can be used to find the value of g and t.
Step-by-step explanation:
Earning at grocery store = $9 per hour
Earning as tutor = $15 per hour
Let the number of hours she tutors = t
and the number of hours she works at grocery store = g
Total earning she wants = $500
Now, the earning from tuition = 15 t
Earning from Grocery store= 9g
According to the question:
g > 2t
15 t + 9g >500
Hence, both the above inequalities can be used to find the value of g and t.
Step-by-step explanation:
In his last 30 throws, Tom hit the target 20 times and missed 10 times.
p = probability he misses the target = ⅓
q = probability he hits the target = ⅔
Using binomial probability:
P = nCr (p)^r (q)^(n-r)
Given n = 3, r = 1, p = ⅓, and q = ⅔:
P = ₃C₁ (⅓)¹ (⅔)³⁻¹
P = (3) (⅓) (⅔)²
P = 4/9
There is a 4/9 probability that he misses exactly 1 of his next 3 throws.
