Answer:
1. 68%
2. 50%
3. 15/100
Step-by-step explanation:
Here, we want to use the empirical rule
1. % waiting between 15 and 25 minutes
From what we have in the question;
15 is 1 SD below the mean
25 is 1 SD above the mean
So practically, we want to calculate the percentage between;
1 SD below and above the mean
According to the empirical rule;
1 SD above the mean we have 34%
1 SD below, we have 34%
So between 1 SD below and above, we have
34 + 34 = 68%
2. Percentage above the mean
Mathematically, the percentage above the mean according to the empirical rule for the normal distribution is 50%
3. Probability that someone waits less than 5 minutes
Less than 5 minutes is 3 SD below the mean
That is 0.15% according to the empirical rule and the probability is 15/100
Step-by-step explanation:
P=Rs4000
Rate(R)=15%
Time(T)=5years
Here,
SI=PTR/100
= 4000×15×5÷100
= Rs3000
Answer:
9.7×10³
Step-by-step explanation:
(3.6×10³) + (6.1×10³) = (3.6+6.1)×10³ = 9.7×10³
___
The factor of 10³ can be factored out while you do the sum.
___
A calculator can find the sum for you. A scientific or graphing calculator will have the option to display the result in scientific notation format.
<h3>Zara earned $ 134 on friday including commission</h3>
<em><u>Solution:</u></em>
Given that,
zahra earns $80 each day plus a 6% commission on her sale at an appliance store
