Answer:
Option b. 12
Step-by-step explanation:
This exercise asks us to find the derivative of a function using the definition of a derivative.
Our function is 
. Therefore:
Then:
Expanding:
Now, if x=0:
1. thousand
2. 50
3. 2,473
4. Nearest hundred's place for 156 is 200 and nearest hunderds place for 235 is 200. The sum of them both is 400.
ok so lets say that you have a pizza cutted out in 5 sections and want to pick up only a certain piece, let's say pepperoni. If you took a piece at random, the chances of getting that certain piece of pepperoni in 60 spins is: 12 / 60
The confidence interval formula is computed by:
Xbar ± Z s/ sqrt (n)
Where:
Xbar is the mean
Z is the z value
S is the standard deviation
N is the number of samples
So our given are:
90% confidence interval with a z value of 1.645
Sample size 40, 45
Mean 180, 179
Standard deviation 2, 4
So plugging that information in the data will give us a
confidence interval:
For 1:
Xbar ± Z s/ sqrt (n)
= 180 ± 1.645 (2 / sqrt (40))
= 180 ± 1.645 (0.316227766)
= 180 ± 0.520194675
= 179.48, 180.52
For 2:
Xbar ± Z s/ sqrt (n)
= 179 ± 1.645 (4 / sqrt (45))
<span>= 179 ± 1.645 (0.596284794)</span>
therefore, the answer is letter b
Answer:
200 minutes, cost $44.00
Step-by-step explanation:
x = minutes
14 + .15x = 22 + .11x
.04x = 8
x = 200 minutes
14 + (.15*200)
14 + 30 = 44
22 + (.11*200)
22 + 22 = 44
