Answer:
B: r =n/2
Step-by-step explanation:
Recondition only mean is that half of what the new is so recondition equals the new over half because recondition is half the price of the new
Answer:
I think It is 8 as well, but not sure
Step-by-step explanation:
Hey there!
Functions are basically like machines you put a number into and they give you a new one as an output. This f represents this machine. f(x) represents whatever the output is because it is the x after it has gone through the function machine.
We want to figure out what x is when f(x)=12. Well, we can simply replace f(x) with 12 in the first equation and solve for x!
12=-16x+8
We flip the equation so x is on the left side.
-16x+8=12
We subtract 8 from both sides.
-16x=4
We divide both sides by -16.
x=-1/4
Have a wonderful day! :D
Answer:
0.71%
Step-by-step explanation:
Given that a normally distributed set of data has a mean of 102 and a standard deviation of 20.
Let X be the random variable
Then X is N(102, 20)
We can convert this into standard Z score by
We are to find the probability and after wards percentage of scores in the data set expected to be below a score of 151.
First let us find out probability using std normal table
P(X<151) = 
We can convert this into percent as muliplying by 100
percent of scores in the data set expected to be below a score of 151.
=0.71%
(x, y)
y = -5x - 1
a. (9, -2) → x = 9, y = -2
-2 = -5(9) - 1
-2 = -46 FALSE
b. (5, 24) → x = 5, y = 24
24 = -5(5) - 1
24 = -26 FALSE
c. (-1, 6) → x = -1, y = 6
6 = -5(-1) - 1
6 = 4 FALSE
d. (-4, 19) → x = -4, y = 19
19 = -5(-4) - 1
19 = 19 TRUE
<h3>Answer: d. (-4, 19)</h3>
