Evie read an article that said 6\%6%6, percent of teenagers were vegetarians, but she thinks it's higher for students at her lar

ge school. To test her theory, Evie took a random sample of 252525 students at her school, and 20\%20%20, percent of them were vegetarians. To see how likely a sample like this was to happen by random chance alone, Evie performed a simulation. She simulated 404040 samples of n=25n=25n, equals, 25 students from a large population where 6\%6%6, percent of the students were vegetarian. She recorded the proportion of vegetarians in each sample. Here are the sample proportions from her 404040 samples: A dot plot for simulated sample proportions has a scale from 0.00 to 0.25 in increments of 0.01. The distribution is right skewed with dots plotted as follows. 0.00, 8. 0.004, 17. 0.08, 5. 0.12, 5. 0.16, 2. 0.20, 2. 0.24, 1. Evie wants to test H_0: p=6\%H 0 ​ :p=6%H, start subscript, 0, end subscript, colon, p, equals, 6, percent vs. H_\text{a}: p>6\%H a ​ :p>6%H, start subscript, start text, a, end text, end subscript, colon, p, is greater than, 6, percent where ppp is the true proportion of students who are vegetarian at her school. Based on these simulated results, what is the approximate ppp-value of the test? Note: The sample result was \hat p=20\% p ^ ​ =20%p, with, hat, on top, equals, 20, percent. Choose 1 answer: Choose 1 answer: (Choice A) A p\text{-value}\approx0.01p-value≈0.01p, start text, negative, v, a, l, u, e, end text, approximately equals, 0, point, 01 (Choice B) B p\text{-value}\approx0.025p-value≈0.025p, start text, negative, v, a, l, u, e, end text, approximately equals, 0, point, 025 (Choice C) C p\text{-value}\approx0.03p-value≈0.03p, start text, negative, v, a, l, u, e, end text, approximately equals, 0, point, 03 (Choice D) D p\text{-value}\approx0.075p-value≈0.075

20) Laila borrowed $9000 from a bank that
iris [78.8K]

Answer:

the answer i think is $259200

Step-by-step explanation:

if the bank charges 7.2% every year, and in this case it's 4 years, then that would mean it would be 28.8%(7.2 x 4), which means the answer would be 9000 x 28.8 which is 259200.

Hope it helped

If the common difference in an arithmetic sequence is 4, and the 20th term is 36, what is the first term?
makvit [3.9K]
4 difference, subtract 20 point - 1st point, =19, 19 places x difference of 4= 76 more or less than 36. More would be 112, less would be -40. A and C are both 40 while choice B = the difference so I'd say it's supposed to be 1 of the 40's but it's missing the negative sign

If (b + 6)/3 = (d + 4)/2, then b/3 = ?<br><br> ???<br> is it d/2??
Nataliya [291]

Answer: b / 3 = d / 2

Step-by-step explanation:

(b + 6)/3 = (d + 4)/2

(b / 3) + (6 / 3) = (d + 4)/2

(b / 3) + 2 = (d + 4)/2

Subtracting 2 from both sides,

(b / 3) + 2 - 2 = ((d + 4)/2) - 2

or, b / 3 = ((d + 4)/2) - 2

or, b / 3 = (d / 2) + ( 4 / 2 ) - 2

or, b / 3 = (d / 2) + 2 - 2

or, b / 3 = d / 2

So,

b/3 is equal to d/2.
