Answer:
<h2>(f · g)(x) = 4x³ + 4x²</h2>
Step-by-step explanation:
(f · g)(x) = f(x) · g(x)
We have f(x) = 4x² and g(x) = x + 1. Substitute:
(f · g)(x) = (4x²)(x + 1) <em>use the distributive property</em>
(f · g)(x) = (4x²)(x) + (4x²)(1)
(f · g)(x) = 4x³ + 4x²
Answer:
the 99% confidence interval for the true mean number of mosquitos caught in all mosquito traps is ( 667.81, 732.19 )
Step-by-step explanation:
Given the data in the question;
sample mean x' = 700
sample size n = 64
the standard deviation σ = 100
99% confidence interval for the true mean number of mosquitos caught in all mosquito traps = ?
significance level ∝ = 1 - 99% = 1 - 0.99 = 0.01
∝/2 = 0.01 / 2 = 0.005
Z-critical = 2.575 { from table }
So, to get the 99% confidence interval;
⇒ x' ± ( σ / √n )
we substitute
⇒ 700 ± 2.575 ( 100 / √64)
⇒ 700 ± 2.575( 12.5 )
⇒ 700 ± 32.1875
⇒ ( 700 - 32.1875 ), ( 700 + 32.1875 )
⇒ ( 667.81, 732.19 )
Therefore, the 99% confidence interval for the true mean number of mosquitos caught in all mosquito traps is ( 667.81, 732.19 )
Answer:
In the context of the problem, $75,000 represents Carmela's initial salary.
Step-by-step explanation:
Her salary is modeled by the following function:
So
At any time we have a function modeled in this following recursive format:
We have that is the initial value of C.
For this problem, we have that C is Carmela's salary. So is Carmela's initial salary. This means that in the context of the problem, $75,000 represents Carmela's initial salary.
The expression that can be used to represent the total price is 3(p - $0.75) + 5(p - $1).
The expression that can be used to determine the total amount spent in store A is:
- number of stickers bought x ( price of the item - discount)
- number of stickers bought = 5
- price of the stickers = p
- discount = $1
5(p - $1)
The expression that can be used to determine the total amount spent in store B is:
- number of stickers bought x ( price of the item - discount)
- number of stickers bought = 3
- price of the stickers = p
- discount = $0.75
3(p - $0.75)
Total price = 3(p - $0.75) + 5(p - $1)
