Answer: No
Step-by-step explanation:
Considering significant: p <= 0.05
A multiple choice question has 18 possible answers, only one of which is correct.
which means that the probability is 1 out 18, so
p = 1/18 = 0.056
As 0.056 > 0.050
Then, it is not significant
Answer:
and 
.
Step-by-step explanation:
So I believe the problem is this:
where we are asked to find values for 
and 
such that the equation holds for any 
in the equation's domain.
So I'm actually going to get rid of any domain restrictions by multiplying both sides by (x-3)(x+7).
In other words this will clear the fractions.
As you can see there was some cancellation.
I'm going to plug in -7 for x because x+7 becomes 0 then.
Divide both sides by -10:
Now we have:
with
I notice that x-3 is 0 when x=3. So I'm going to replace x with 3.
Divide both sides by 10:
So and .
Answer:
$19.76
Step-by-step explanation:
First you turn the 15% to 0.15 and then you multiply it with $25 to get 3.75.
That isn't the meal though, but the discount you are going to get.
Now subtract 3.75 from 25 to get $21.25
After that multiply 21.25 with 7% which gets you 1.4875
Then, subtract 1.4875 from 21.25 to get 19.7625 which is rounded to $19.76
Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Answer:
d = 7.2
Step-by-step explanation:
12 + d = -4.8
subtract 12 from both sides and you get
d = 7.2
