-4arccos(x^(1/4)) +C
Step-by-step explanation:
My machine solver gives an answer that reduces to the expression ...
-4arccos(x^(1/4)) +C
__
We know that ...
(d/dx)arccos(x) = -1/√(1-x²)
If you let u = x^(1/4), then you can make the integrand look something like ...
4 du/√(1 -u²)
which is what you need to get to the arccos function.
Order this set of numbers from greatest to least. Then explain the order, referring to the number line in your explanation.

Question 7 of 10
For which sample size (n) and sample proportion (6) can a normal curve be
used to approximate the sampling distribution?
O A. n = 45; Ø = 0.8
O B. n = 90; 0 = 0.9
O C. n = 90; i = 0.8
D. n = 45; P = 0.9
SUBMIT
Answers
Answer:
C. n = 90; p = 0.8
Step-by-step explanation:
According to the Central Limit Theorem, the distribution of the sample means will be approximately normally distributed when the sample size, 'n', is equal to or larger than 30, and the shape of sample distribution of sample proportions with a population proportion, 'p' is normal IF n·p ≥ 10 and n·(1 - p) ≥ 10
Analyzing the given options, we have;
A. n = 45, p = 0.8
∴ n·p = 45 × 0.8 = 36 > 10
n·(1 - p) = 45 × (1 - 0.8) = 9 < 10
Given that for n = 45, p = 0.8, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution
B. n = 90, p = 0.9
∴ n·p = 90 × 0.9 = 81 > 10
n·(1 - p) = 90 × (1 - 0.9) = 9 < 10
Given that for n = 90, p = 0.9, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution
C. n = 90, p = 0.8
∴ n·p = 90 × 0.8 = 72 > 10
n·(1 - p) = 90 × (1 - 0.8) = 18 > 10
Given that for n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution
D. n = 45, p = 0.9
∴ n·p = 45 × 0.9 = 40.5 > 10
n·(1 - p) = 45 × (1 - 0.9) = 4.5 < 10
Given that for n = 45, p = 0.9, n·(1 - p) = 4.5 < 10, a normal distribution can not be used to approximate the sampling distribution
A sampling distribution Normal Curve
45 × (1 - 0.8) = 9
90 × (1 - 0.9) = 9
90 × (1 - 0.8) = 18
45 × (1 - 0.9) = 4.5
Now we will investigate the shape of the sampling distribution of sample means. When we were discussing the sampling distribution of sample proportions, we said that this distribution is approximately normal if np ≥ 10 and n(1 – p) ≥ 10. In other words
Therefore;
A normal curve can be used to approximate the sampling distribution of only option C. n = 90; p = 0.8

Definition of Probability Probability means possibility of occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some random events.Given marbles 10 red, 10 blue, 8 green, 8 purple, and 8 yellow marbles .
Therefore total marbles will be 44.
Since the first student in the room draws a yellow, and the second draws a blue ,thus remaining marbles will be 42.
So, the probability that the third student will draw a green is [tex]\frac{8}{42}[/tex]×[tex]100\\[/tex] = 19%

1. John's weight at his last five doctors' appointments has been 180 lbs, 170 lbs, 168 lbs, 184 lbs, and 182 lbs. What must John's
welght be at his next doctor's appointment to have a mean weight of 175 lbs?
Answers
Answer:
166
Step-by-step explanation:
1050-884=166
6x175=1050
Answer:
[tex] \boxed{166\: lbs \: [pounds \: of \: weight]} [/tex]
Step-by-step explanation:
Mean =
Sum of data / # of data
Mean =
(180 lbs + 170 lbs + 168 lbs + 184 lbs + 182 lbs) / (5)
Since the weight of the next doctors appointment is unknown and must equal a mean weight of 175, there will be one more data point and we will let x represent this unknown weight:
175 lbs = (180 lbs + 170 lbs + 168 lbs + 184 lbs + 182 lbs + x lbs) / (5 + 1) →
175 lbs = (884 lbs + x lbs) / (6) →
(884 lbs + x lbs) / (6) = 175 lbs →
(884 lbs + x lbs) / (6) × 6 = 175 lbs × 6 →
884 lbs + x lbs = 1050 lbs →
(884 + x) lbs = (1050) lbs →
(884 + x = 1050) lbs →
(884 + x – 884 = 1050 – 884) lbs →
(x = 1050 – 884) lbs →
x = 166 lbs
_____________________________
166 lbs must be the weight for the mean of these weights to be 175 because:
(180 lbs + 170 lbs + 168 lbs + 184 lbs + 182 lbs + x lbs) / (5 + 1) →
(180 lbs + 170 lbs + 168 lbs + 184 lbs + 182 lbs + 166 lbs) / (5 + 1) →
(1050 lbs) / 6 →
175 lbs
