Question 2 of 10
For which sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution?
A. n = 65; p = 0.9
O B. n = 35; p = 0.9
C. n = 35; p = 0.8
O D. n = 65; 6 = 0.8
Answers
Answer:
n = 65; p = 0.8
Step-by-step explanation:
The sample size (n) and sample proportion () can a normal curve be
used to approximate the sampling distribution is n = 65, p = 0.8.
The correct option is D.
According to the Central Limit Theorem, the shape of sample distribution of sample proportions with a population proportion, 'p' is normal
If n·p ≥ 10 and n·(1 - p) ≥ 10.
n = 65, p = 0.8
∴ n·p = 65 x 0.8 = 52 > 10
n·(1 - p) = 65 × (1 - 0.8) = 13 > 10
For n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution.

Answer:
x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)
Step-by-step explanation:
Given quadratic equation:
16x² - 20x - 6 = 0
Quadratic formula is given by:
x = -b² ± √b² - 4(a)(c) / 2a
16x² - 20x - 6 = 0
From the equation,
a = 16
b = -20
c = -6
x = -b² ± √b² - 4(a)(c) / 2a
x = -(-20)² ± √(-20)² - 4(16)(-6) / 2(16)
x = -(400) ± √(400) - (-384) / 32
x = -400 ± √400 + 384 / 32
x = -400 ± √784 / 32
x = -400 ± 28 / 32
x = (-400 + 28) / 32 or x = (-400 - 28) / 32

Write an exponential function in terms of x.

y-DO
Answers
Answer:
291050 people
Step-by-step explanation:
The formula for exponential growth is given by; a(1 + r)ⁿ
where;
a is the initial population
r is the rate of change
y is the final population
x is the number of years
r is the rate of change
We are given;
Initial population; a = 140000
Rate; r = 5% = 0.05
Number of years; x = 15 years
Thus, in terms of x;
y = 140000(1 + 0.05)^(x)
Now, after 15 years, we now have;
y = 140000(1 + 0.05)^(15)
y = 291049.94511
Approximating to a whole number gives;
y = 291050 people

Answer:
Order from greatest to least: 10.5, [tex]3\pi +1[/tex], [tex]\sqrt{105}[/tex]
Step-by-step explanation:
step 1 simplify each number
3π + 1 = 10.4247779
*round to the nearest tenth*
3π + 1 = 10.4
[tex]\sqrt{105} =10.2469507[/tex]
*round to the nearest tenth*
[tex]\sqrt{105} =10.2[/tex]
10.5 = 10.5
Now that we have simplified each number we can easily put them in order from greatest to least
10.5 is the greatest number
10.4 is the middle number
10.2 is the lowest number
so 10.5, 10.4, 10.2
Now we put them back in the original form
10.5 = 10.5
10.4 = 3π + 1
10.2 = [tex]\sqrt{105}[/tex]
Your answer is
10.5 , 3[tex]\pi[/tex] + 1, [tex]\sqrt{105}[/tex]

What is the Pythagorean theorem?The Pythagorean theorem is a fundamental theorem in geometry that describes the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In algebraic terms, the Pythagorean theorem can be written as:
a² + b² = c²
where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.
Here,
We can use the Pythagorean theorem to solve this problem. Let's denote the distance from the bottom of the wall to where the ladder reaches the wall as h. Then we have,
h² + 4² = 13²
h² + 16 = 169
h² = 153
h ≈ 12.37
Therefore, the ladder reaches approximately 12.37 feet up the wall.

How many years will it take for $136,000 to grow to $468,000 if it is invested in an account with an annual interest rate of 8%?
Answers
Answer:
=21.29%(Approx).
Step-by-step explanation:
We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.
a.
468,000=136,000*(1.08)^n
(468,000/136,000)=(1.08)^n
Taking log on both sides;
log (468,000/136,000)=n*log 1.08
n=log (468,000/136,000)/log 1.08
=16.06 years(Approx).
b.
475,000=10,000*(1+r/100)^20
(475,000/10,000)^(1/20)=(1+r/100)
(1+r/100)=1.2129
r=1.2129-1
=21.29%(Approx).
