In this question, it's asking you how much the tip would be for the bill.
Lets get some important information from the question:
With the information above, we can solve the problem.
In order to find how much they need to tip the waiter, we would need to multiply 26.50 by 0.20
We would do this because we need to know how much of 26.50 is 20%
Lets solve:
When you multiply, you should get 5.30
This means the tip would be $5.30 for a bill that costs $26.50

Step-by-step explanation:
Given the equation you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:
Now you need to add 21 to both sides of the equation:
Subtract from both sides:
And finally, you can divide both sides of the equation by 18:
Answer:
a) 99.7%
b) 68%
c) 68% of organs weighs between 275 and 365 grams, so 32% of organs weighs will be less than 275 or more than 365 grams.
d) 81.5% of organs weighs between 290 grams and 365 grams.
Step-by-step explanation:
A) 99.7% of organs will be between 3 standard deviation from the mean.
So 99.7% of organs will be between 185 and 455.
B) 275 grams and 365 grams are 1 standard deviation from the mean.
From empirical rule about 68% data falls within 1 standard deviation from the mean.
So 68% of organs weighs btwn 275 grams and 365 grams.
C) Since 68% of organs weighs between 275 and 365 grams, so 32% of organs weighs will be less than 275 or more than 365 grams.
D) 230 is 2 standard deviation below the mean and 365 is one standard deviation above the mean.
According to the empirical rule, 95% of the observation lies within 2 standard deviations of the mean. Therefore 5% lies outside 2 standard deviations of the mean.
So 95%/2 = 47.5% of organs weighs between the mean and 230 grams.
According to the empirical rule about 68% data falls within one standard deviation from the mean.
so, 68%/2 = 34% of organs weighs between the mean and 365 grams.
So total = 47.5% + 34% = 81.5% of organs weighs between 290 grams and 365 grams.
Answer:
$1480.24
Step-by-step explanation:
This will be solved by the formula:
Where
FV is the future value (what we are looking for)
I is the initial amount (which is $1000)
r is the rate of interest per period (8% is annual interest, but the period is SEMI-ANNUAL, that's 6 months, half of yearly. So r would be half of 8%, which is 4% or r = 0.04)
t is the times compounding occurs in the whole time (The whole time period is 5 years, but compounding occurs semi-annually, so 5*2 = 10 times. Thus, t = 10)
<em>plugging the info into the formula we will get our answer.</em>
