Answer:
The band cannot sell .67 of a DVD, so the Jefferson band boosters sold more than 3,666 DVDs.
Step-by-step explanation:
Let 
equal the number of band DVDs sold.
Start with:
Divide both sides of the inequality by 
(Round!):
Answer:
51-2x
Step-by-step explanation:
Answer:
<h2>65°</h2>
Step-by-step explanation:
Complementary means that the two angles add to 90 degrees. Since we know the measure of one angle, we will subtract 25 from 90 to get 65 degrees for angle 2.
Answer:
The null hypothesis is that there is no difference in the mean number of male and female cats
H₀; μ₂ - μ₁ = 0
Step-by-step explanation:
The given parameters are;
The given percentage of male stray cat population = 50%
The given percentage of female stray cat population = 50%
The number of areas the researcher visits, n = 15
The number of stray male cats he finds = 11
The kind of test to be performed = Sign test
The significance level, α = 0.05
A) Therefore the null hypothesis is H₀; μ₂ - μ₁ = 0
The alternative hypothesis is Hₐ; μ₂ - μ₁ ≠ 0.
Answer:
B: 3/4
Step-by-step explanation:
Since we know this is an exponential function
y= ab^x
where a is the initial value and b is the growth rate or what we multiply by
For the first point x=1 and y = 3/2
3/2 = a b^1
3/2 = a*b
For the second point x=2 and y = 9/8
9/8 = a b^2
Take the second equation over the first
9/8 = a b^2
-------------------
3/2 = a*b
3/4 = b
The growth rate is 3/4
That would also be know as the rate of change
