What is the average rate of change for the function f(x)=3(0.25)^x over the interval -2 ≤ x ≤ 0

diamong [38]

Answer:
-22.5

Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48

(3-48)/ 0-(-2)
(-45) / 2
-22.5

Answer:

$41.1units^2$

Step-by-step explanation:

$A=\frac{h_{b}b }{2} \\=\frac{8*4}{2} \\=16units^2$ (triangle)

$A=\frac{\pi r^2}{2}\\\frac{\pi 4^2}{2}\\=25.13units^2$ (semicircle)

Add both together

$16+25.13\\=41.13units^2$

Suppose that past history shows that 60% of college students prefer brand c cola. a sample of 5 students is to be selected. base

creativ13 [48]

The probability is 0.337.

The probability that more than 3 prefer brand c is the same as finding the probability that 4 or 5 prefer brand c. Using a binomial distribution,

$_5C_4(0.6)^4(0.4)^{5-4}+_5C_5(0.6)^5(0.4)^{5-5}
\\
\\=\frac{5!}{4!1!}(0.6)^4(0.4)^1+\frac{5!}{5!0!}(0.6)^5(0.4)^0
\\
\\=5(0.6)^4(0.4)+1(0.6)^5(1)=0.33696\approx0.337$
