Answer:
B. 3a/a-2
Step-by-step explanation: according to e2020
Answer:
interval in minutes = (24.88, 35.12)
Step-by-step explanation:
we can use the following formula:
interval = population mean ± (z · σ)
- population mean = 30 minutes
- z for 80% = 1.28
- σ = 4 minutes
interval = 30 minutes ± (1.28 · 4 minutes)
interval in minutes = (30 - 5.12), (30 + 5.12) = (24.88, 35.12)
Reduce the fractions then do the math I always forget to flip the fraction then multiply it by the fraction it already was
If the function is vertically compressed, the resulting function will be g(x) = 3/4x^2
<h3>Vertical compression of a function</h3>
Quadratic functions are functions that has a leading degree of 2. Given the parent function f(x) = ax^2
where
2 is the exponent/degree
If the function is vertically compressed, the value of a must be less than 1, hence the possible expression when vertically compressed is g(x) = 3/4x^2
