Step-by-step explanation:
This is confusing, what does g(x) equal? There's a bunch of random numbers there. I'll just assume.
They stated that f(x) needs to exceed g(x), so make an inequality plugging in the values
You see, function f(x) needs to be higher than function g(x)
Subtract 7x from both sides to get:
Divide both sides by -4, when you divide by a negative number the signs switch so it is now less than.
x < -1.5
And obviously that's not an answer up there, so you made a mistake stating the values of the functions
Answer:
Im not 100% sure but i know 2 and 4 are correct, the rest I think are all wrong but im not sure sorry
Answer:
Step-by-step explanation:
a) sub in 600 for 6
600-25/40 =14.375
b) switch x and y
x=y-25/40
Solve for y
40x=y-25
y=40x+25
c)Plug in 2.5 for z(x)
2.5= x-25/40
100=x-25
x=125
Answer:
yes
Step-by-step explanation:
So the circumfrehce of a circle is basically the perimiter of the circle. Let me help with number 1. We need to find the radius. In order to do tuis we divide 6 in half giving us 3. Then we plug in 3 into the circumfrence formula (Pi times the radius multiplied by 2). So it would be 3.14*3*2. The answer for number 1 is 18.85
Answer: 0.1824
Step-by-step explanation:
Given : The mileage per day is distributed normally with
Mean : 
Standard deviation : 
Let X be the random variable that represents the distance traveled by truck in one day .
Now, calculate the z-score :-
For x= 132 miles per day.
For x= 159 miles per day.
Now by using standard normal distribution table, the probability that a truck drives between 132 and 159 miles in a day will be :-
Hence, the probability that a truck drives between 132 and 159 miles in a day =0.1824
