Remove parentheses and combine like terms...
then subtract constants from both sides
isolate variables and constants
use the division property and solve for x
I’m not sure but for Louise it’s cost $1.52 and for Thelma is $1.26 . What you basically do is divide
I believe it’s B. hope it’s right!
Answer:
use 5th and the 95th percentile of these values.
Step-by-step explanation:
To find the 90% confidence interval for the population standard deviation, randomly sample with replacement from the original sample thousands of times. From each new sample, you compute the sample standard deviation. Using the bootstrap method, we can find the 90% confidence interval for the population standard deviation,from the values of 5th and the 95th percentile of these values.
So we need to use 5th and the 95th percentile of these values.
Do 340 ✖️0.20, and you'll get 68. Since that's 20% of 340, do 340 ➖ 68 and you'll get your final answer.
