Answer:
Step-by-step explanation:
In a World Atlas study, 10% of people have blue eye color. Lane decided to observe 29 people and she concluded 5 people had blue eyes. Calculate the z-score
Given that :
Sample size (n) = 29
Number of people with blue eyes (x) = 5
Proportion (p) = 10% = 0.1
Using the relation :
Z = (p" - p) / sqrt(pq/n)
Recall : q = 1 - p = 1 - 0.1 = 0.9
p" = x / n = 5 / 29 = 0.1724137
pq = 0.1 * 0.9 = 0.09
Hence,
Z = (0.1724137 - 0.1) / sqrt(0.09/29)
Z = 0.0724137 / 0.0557086
Z = 1.2998657

Answer:
<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ =
0</h3>
Step-by-step explanation:
Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰
S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰
S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀
then, S is the sum of 100 consecutive terms of a geometric sequence (an)
where the first term a1 = i¹ = i and the common ratio = i
FORMULA:______________________
_______________________________
then
or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)
Hence
S = 0
Answer:C. 3000 ft
Step-by-step explanation:
First, find the radius of the circumference.
By dividing 1000 ft by 2, which is 500, and that is the radius.
Then you multiply the radius by 3, which is 1500.
Finally, you want the circumference, to find the circumference you need to multiply the radius by 2, which is 3000 ft.
That’s it.
Answer:An inverse operation are two operations that undo each other addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations i guess a little bit of fraction might help if im right idk but forget the fraction part just read the other.
