Answer:
Step-by-step explanation:
hello :
an Degree 3 polynomial with zeros 4, 6, and -2 is :
f(x) = (x-4)(x-6)(x+2)
all polynomial are : a (x-4)(x-6)(x+2) a ≠ 0
Well if she added three blue and four red originally, and is now using 16 red then we would divide 16 by the original four. Which means to get the number of blue we are gonna end up multiplying by four. So three times four is twelve. Which means she would use 12 blue and 16 red to get the same color she got with 3 blue and 4 red earlier. The equation, lets use x for blue and y for red, would be 4(3x + 4y) = desired color
Multiply by 4 is your rule
3 x 4 = 12
6 x 4 = 24
12 x 4 = 48
To solve for the answer for 24, multiply it by 4
24 x 4 = 96
96 is the match for 24
hope this helps
Answer:
the standard error of the proportion is 0.0272
Step-by-step explanation:
We have that if the sample size is greater than 5% of the entire population, a finite population correction factor (fpc) is multiplied with the standard error
:
fpc = 
We know that N = 250 n = 91, replacing:
fpc = 
fpc = 0.799
Now, the formula would then be:
SE = 
*fpc
Now replacing, knowing that p = 0.12
SE= 
*0.799
SE = 0.0272
So the standard error of the proportion is 0.0272
Answer:
900 j
Step-by-step explanation:
KE=1/2mv^2
so:
1/2x(2kg)x(30m/s)^2
is 900 joules. :)
