Answer: Yes, it is a solution
Step-by-step explanation:
So in the parenthesis, 4 is x and 5 is y, since x comes before the y. Plug the 4 in where the x is, and the 5 where the y is, and you should get 5= 12-7. 12-7 does equal 5, therefore it is a solution :)

Step-by-step explanation:
From the information on 60 students we write frequency distribution as
x    1     2     3     4      5       6   7   total
f     13    22    15     6      3       0   1    60
C Â Â Â 13 Â Â Â 35 Â Â Â 50 Â Â 56 Â Â Â 59 Â Â Â Â Â 59 Â Â 60
xf    13    44   45    24     15       0   7    148
x^2f  13    88   135   96    75       0  49    456
Mean = 2.67
Var = 445.92
Std dev = 21.21
I quartile = 2
III quartile = 3
20% have atmost 1
Answer:
Step-by-step explanation:
In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.
Speed is inversely proportional to the time taken
speed is 18 miles per hour and distance is 216 miles
Let 's' be the speed and 't' be the different time
Replace distance by 216
Answer:
4! = Â 24.
Step-by-step explanation:
Each square can be replaced by one another to make an unique combination.
For example
The First square is red and second one is blue, and green and yellow respectively. All these squares can change position with eachother.
Which make it 24 Possibilities in total.
Answer:
$14.4
Step-by-step explanation:
The original price of dry cleaning a vest = $5
The new price of dry cleaning a vest = $6
The percentage increase is obtained by
× 100
×100 = 20%
hence, there is a 20% increase in price.
applying this 20% increase to the cost of dry cleaning, the new cost will become
×12
this is a 120% increase in cost.
mathematically this can be solved by
×12 = $14.4
hence, the new cost of dry cleaning is $14.4
Answer:
F(x)=sin(2)*-cos(x) +10x + 8
Step-by-step explanation:
in order to find F(x) you need to integrate two times.
-> First time
F'(x) = sin(2)*x + sin(x) + C,
if F'(0)=10 then F'(0)=sin(2)*(0) +sin(0) +c=10, so c=10.
Replacing C=10
F'(x) = sin(2)*x + sin(x) + 10.
-> Second time
F(x)=sin(2)*-cos(x) +10x +
if F(0) = 7 then sin(2)*0 - cos(0) + 10*0 +=7
so =8
Replacing this
F(x)=sin(2)*-cos(x) +10x + 8
If f(0)=10 and f'(0)=7 the answer is F(x)=sin(2)*-cos(x) +7x + 11
if F''(x)=sin(2x)+cos(x), f(0)=10, f'(0)=7 , the answer is F(x)=-sin(2x)/4 -cos(x) +15x/2+11
