Answer:
[-8,8]
Step-by-step explanation:
domain is the set of x values that the graph covers
This graph starts at -8 and ends at 8 (including those points and all points between them).
That makes the domain [-8,8]
Answer:
x= 12 and y= 2
Step-by-step explanation:
First you would line up the equations so the x's and y's are on top of each other. Then you would multiply x+y=14 by 3 to give you 3x+3y=42. After that you subtract 2x-3y=30 and 3x+3y=42 to give you an answer of x=12. After that, you plug in x with 12 in the equation x+y=14. You subtract 12 from both sides to get an answer of 2. So ur solution is (12,2)
Answer:
Step-by-step explanation:
Since the distance travelled on 1 gallon of fuel is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = the distance travelled.
µ = mean distance
σ = standard deviation
From the information given,
µ = 50 miles
σ = 8 miles
A) P(x > 53) = 1 - P(x ≤ 53)
For x = 53,
z = (53 - 50)/8 = 0.38
Looking at the normal distribution table, the probability value corresponding to the z score is 0.648
B) P(x < 42)
For x = 42
z = (42 - 50)/8 = - 1
Looking at the normal distribution table, the probability value corresponding to the z score is 0.1587
C) P(44 ≤ x ≤ 53)
For x = 44
z = (44 - 50)/8 = - 0.75
Looking at the normal distribution table, the probability value corresponding to the z score is 0.2266
For x = 55,
z = (55 - 50)/8 = 0.63
Looking at the normal distribution table, the probability value corresponding to the z score is 0.7357
Therefore,
P(44 ≤ x ≤ 53) = 0.7357 - 0.2266 = 0.5091
Answer:
(F). People may have a career following their passion, but have a low income or a long commute.
(A). A working spouse could affect all three variables. (C).People might be very satisfied with their career as long as the income is high.
(E). One-way commute times may be long because affordable housing is distant from the job.
Step-by-step explanation:
a. People may have a career following their passion, but have a low income or a long commute.
sometimes people can get jobs based on their passion but might still have low income and a long commute.
b. A working spouse could affect all three variables.
Yea a working spouse considers the income rate, job satisfaction and commute time involved in a job because it can affect their daily lives.
c. People might be very satisfied with their career as long as the income is high.
Most people are more satisfied with their career when the income rate is high.
d. One-way commute times may be long because affordable housing is distant from the job.
Income rate affects the choice of accommodation and housing.
