2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000
compare
20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C
we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200
answer is C
Given. Total 8 math class, 222 students in total. One class is 32 student and 7 equally size.
Use 221 - 32 = 189 students
Let x be the equally size. 7x=189, x= 27 students
Hey there! :)
Answer:
C. (f + g)(x) = 3x² + 3x/2 - 9
Step-by-step explanation:
(f + g)(x) requires you to add functions f(x) and g(x) together. Therefore:
(f + g)(x) = x/2 - 3 + 3x² + x - 6
Combine like terms:
(f + g)(x) = 3x² + x + x/2 - 3 - 6
Simplify:
(f + g)(x) = 3x² + 3x/2 - 9
Therefore, the correct answer is C.
A function is a type of relation in which there is only one output value for each input value so the domain will not repeat if it is going to be a continuous graph remember there will be no dots just curves and 00 origin
Answer:
a) 48.408
b) 1.235
Step-by-step explanation:
a)
The average hardness value xbar can be computed as
xbar=sum of values/number of values
xbar=(46.5+46.9+49.4+50.3+49.8+48.8+47+47.7+48.3+49.4+47.8+49)/12
xbar=580.9/12
xbar=48.408 (rounded to 3 decimal places).
The average hardness value is 48.408.
b)
The standard deviation hardness value s can be computed as
x x-xbar (x-xbar)

49.0 0.59167 0.35007
Total 16.7692
s=1.235 (rounded to 3 decimal places)
The standard deviation hardness value is 1.235.
