Answer:
No
Step-by-step explanation:
By definition,
mutually exclusive events cannot occur together.
The simplest example of mutually exclusive events is a coin toss. A tossed coin outcome can be either head or tails, but both outcomes cannot occur simultaneously.
B. Above par
C. On par
D. Par equality
The Correct Answer Is B- Above Par
On the highway, Kareem's car gets 38 mpg.
Shu Fang has $25.75 deducted from her checking account every month.
A toad population is increasing by about 7.5% each year.
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
Answer: A toad population is increasing by about 7.5% each year.
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
Step-by-step explanation:
On the highway, Kareem's car gets 38 mpg.
This can be modeled with a linear relationship between the miles and the gallons of fuel needed.
Shu Fang has $25.75 deducted from her checking account every month.
Here we know that each month a constant amount is deducted from her, this is not an exponential relation.
A toad population is increasing by about 7.5% each year.
If the population initially was an amount P, after one year the population is P*1.075, after two years the population is P*(1.075)^2 and so on, this can be modeled with an exponential function where the years variable, the function will have the general form:
Population(y) = P*(1.075)^y
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
If the first year the population is X, the year after the attendance will be (4/5)X, and the year after this process applies again, so you have a 4/5 of the previous attendance, the attendance now is (4/5)^2*X
This also can be modeled with an exponential function, of the shape:
Attendance (y) = X*(4/5)^y, where again, y means years.
The thing you may notice is that in this case the model only works for the lapse of 5 years that the event organizer said.
B) 80 mph
C) 40 mph
Alright, lets get started.
A light private plane can fly 120 mph in still air.
Suppose the speed of wind = x mph
Against the wind, speed of plane will be = 120-x
With the wind, speed of plane will be = 120+x
Flying against the wind, the plane can fly 320 miles, so time taken will be
t =
With the wind, the plane can fly 640 miles, so time taken will be
Both times are given same, so
Cross multiplying
Dividing from 320
x = 40 mph
So, the speed of the wind is 40 mph. : Answer
Hope it will help :)
Answer:
40
Step-by-step explanation:
B) (-1)(-1)(-1)(-1)
C) (-1)(-1)(-1)(-1)(-1)
D) (-1)(-1)(-1)(0)
i'm pretty sure it's C
-1 times -1 becomes positive, and then times -1 again, it's negative, and times it again, it's positive, and THEN one more time (lol) it's -1.
