Answer:
B) 5 5/8in x 9in is your answer
Step-by-step explanation:
First add the bottom numbers together (9+6+9) which gives you 24. Then multiply both sides by 3/8 (15 x 3/8= 5 <u>5/8</u>) and (24 x 3/8= <u>9</u>) making your answer 5 5/8 x 9
Answer:
a) 2.188
b) John's rent is not an outlier
c) His rent has to be higher than $1,235 to be an outlier
Step-by-step explanation:
The mean monthly rent of students at Oxnard University is $780 with a standard deviation of $208.
(a) John’s rent is $1,235. What is his standardized z-score?
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = $1235
μ is the population mean = $780
σ is the population standard deviation = $208
Hence,
z = 1235 - 780/208
z = 2.1875
Approximately to 3 decimal place = 2.188
(b) Is John’s rent an outlier?
No it isn't
(c) How high would the rent have to be to qualify as an outlier?
John’s rent would have to be higher than $1235
Answer:
(1 - 2/5) shirts are left
x ≥ 200
Solution means that before 2/5 shirts were sold, there were 200 shirts.
Step-by-step explanation:
Given in the question the inequality
3/5x + 30 ≥ 150
Suppose number of shirts that were on display = x
A)
Explain what 3/5 means in the in equality
As stated in the question2/5 of the shirts are sold means
(1 - 2/5) shirts are left
3/5 = (1 - 2/5)
B)
3/5x + 30 ≥ 150
3/5x ≥ 150 - 30
3/5x ≥ 120
x ≥ 120 * (5/3)
x ≥ 200
C)
Solution means that before 2/5 shirts were sold, there were 200 shirts.
