Answer:
= Sh. 2281.50
Step-by-step explanation:
Area of the path;
(126 × 2.5 ) + (2.5 × (48 - (2.5×2)
= 315 + (2.5 × 43)
= 315 + 107.5
= 422.5 m²
But; the cost of graveling is sh 5.40 per square meter
Therefore; The cost of graveling the whole path;
= 422.5 × 5.40
<u>= Sh. 2281.50</u>
A function will not have any repeating x values...it can have repeating y values, just not the x ones
{(0,2),(3,8),(-4,-2),(3,-6),(-1,8),(8,3)}
u would have to remove one of the sets of points that has 3 as its x value....so either remove (3,8) or (3,-6)....because with both of them in there, u have repeating x values
Answer: 3
Step-by-step explanation: This equation can be written as 4x+3x-4=17
We can now solve.
Moving the 4 to the other side (adding) and we get 21.
Now we have 4x+3x. Adding like terms, we get 7x = 21. Now we divide by 7.
X = 3.
Answer: a. $128.125
Step-by-step explanation:
The standard error of the mean is given by :
, where
= population standard deviation , n= sample size.
Given: 
n= 256
Then, the standard error of the mean:-

Hence, option a. is correct.
