Answer:
represent the proportion estimated of subjects reported with dizziness
n = 268 represent the random sample selected
represent the proportion of subjects No reported with dizziness
E= 0.04 = 4% represent the margin of error for the confidence interval
and this value represent the significance level of the test or the probability of error type I
Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The population proportion have the following distribution
Solution to the problem
The confidence interval for the mean is given by the following formula:
The margin of error is given by:
And for this case we have the following info:
represent the proportion estimated of subjects reported with dizziness
n = 268 represent the random sample selected
represent the proportion of subjects No reported with dizziness
E= 0.04 = 4% represent the margin of error for the confidence interval
and this value represent the significance level of the test or the probability of error type I
Answer:
x = - , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
x - 2 = 0 ⇒ x = 2

n starts at 1, and n is a positive whole number (1,2,3,...)

Explanation:
The sequence is arithmetic with first term 40 and common difference 10. Meaning we add 10 to each term to get the next one.
--------
a1 = 40 = first term
d = 10 = common difference
is the general nth term of this arithmetic sequence
Plug in n = 1 and you should get
Plug in n = 2 and you should get
and so on
