Answer:
13/145
Step-by-step explanation:
The average rate of change of f(x) on the interval [a,b] is f(b)−f(a) / b−a.
We have that a=0, b=8, f(x)=2x−1 / 3x+5.
Thus, f(b)−f(a) / b−a =
[{(2(8)−1)/(3(8)+5)} − {(2(0)−1)/(3(0)+5)}] / {8−(0)} =
13/145
Answer: (0.760, 0.820)
Step-by-step explanation:
Let p be the population proportion of all adults feel that "education and our schools" is one of the top issues facing California.
Given : 79% (actual results are 400 out of 506 surveyed) of California adults feel that "education and our schools" is one of the top issues facing California.
i.e.Sample size : n= 506
Sample proportion : 
Critical value for 90% confidence interval ( Using z-value table) :

Now, the 90% confidence interval for the population proportion will be :

i.e. 
i.e. 

Hence, the 90% confidence interval for the population proportion= (0.760, 0.820)
We take each number as x = 2x 3x 4x
(2x)³+(3x)³+(4x)³=33957
8x³+27x³+64x³=33957
99x³=33957
x³=33957÷99
=∛343
x=7
2x=2×7=14
3x=3×7=21
4x=4×7=28
=the three numbers are 14,21,28
Answer:
0.026 m / min.
Step-by-step explanation:
Volume V = π7^2h
V = 49πh
dV/dh = 49π
Rate that the volume is increasing is 4 m3/min.
So dV/dt = 4
dV/dt = dh/dt * dV/dh
4 = dh/dt * 49π
dh/dt = 4/49π
= 0.026 m / min.
