Use the formula
a_n = a_1•r^(n-1)
a_23 = 25•(1.8)^(23 - 1)
Can you finish?
So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is

Well we know that the radius = 3.14
And we know that
= 3.14 as well.
All we have to do is multiply..
3.14 x
= 30.95
So the area of the pie is 30.95 in
Good Luck! :)
U=6 u add 5u and u get 8u on the left side then u divide by 8 and u get 6 so U=6
Answer:
y = 2x + 5
Step-by-step explanation:
First, find the slope using rise over run, (y2 - y1) / (x2 - x1)
With this information, we can create 2 points: (2, 9) and (5, 15)
Plug in the points:
(15 - 9) / (5 - 2)
6 / 3
= 2
Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
15 = 2(5) + b
15 = 10 + b
5 = b
Plug in the slope and b into the equation:
y = 2x + 5 is the equation of the line
Answer:
The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022
Step-by-step explanation:
Upper Limit for 95% Confidence Interval can be calculated using p+ME where
- p is the sample proportion of defective gaming systems (
)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the statistic of 95% confidence level (1.96)
- p is the sample proportion (

- N is the sample size (1200)
Using the numbers we get:
ME=
≈ 0.007
Then upper limit for the population proportion is 0.015+0.007 =0.022
