Answer:
Percentage of Taxes = 10.689 %
Step-by-step explanation:
Given that
Total earning of Anna is $442.50
The amount which is held with Taxes = $47.30
Now in terms of percentage
percentage of taxes from her total earning = 
So % taxes = ( 0.106892) × 100
∴ Taxes percentage = 10.689 %

Answer: provided in the explanation segment
Step-by-step explanation:
(a). from the question, we can see that since that б is known, we can use standard normal, z.
we are asked to find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error?
⇒ 80% confidence interval for the average weight of Allen's hummingbirds is given thus;
x ± z * б / √m
which is
3.15 ± 1.28 * 0.32/√10
= 3.15 ± 0.1295 = 3.0205 or 3.2795
(b). normal distribution of weight (c) б is known
(c). option (a) and (e) are correct
(d). from the question, let sample size be given as S
this gives';
1.28 * 0.32/√S = 0.15
√S = (1.28 * 0.32) / 0.15 = 2.73
S = 7.4529
cheers i hope this helps
Answer: 2
Step-by-step explanation:
You are not really asked how to find the solutions, just how many there are. The easiest way to solve this is to use a program like Desmos and graph the question. I have done this for you.
Red: line -2x + 1
Blue: quadratic y = -2x^2 + 1
