Answer:
Selling price= $58.5
Step-by-step explanation:
Giving the following information:
Guitar cost price= $45
Mark up percentage= 30%
<u>To calculate the selling price of the guitar, we need to use the following formula:</u>
Selling price= cost price*(1+mark up)
Selling price= 45* (1+0.3)
Selling price= 45*1.3
Selling price= $58.5

Answer:
The probability that it takes Annie between 39 and 40 minutes given that it takes less than 44 minutes for her to make dinner is 0.04.
Step-by-step explanation:
Let <em>X</em> = amount of times (in minutes) it takes Annie to make dinner.
The random variable <em>X</em> follows a continuous Uniform distribution with parameters <em>a</em> = 19 minutes and <em>b</em> = 49 minutes.
The probability density function of continuous Uniform distribution is:
Compute the value P (39 < X < 40 | X < 44) as follows:
Thus, the probability that it takes Annie between 39 and 40 minutes given that it takes less than 44 minutes for her to make dinner is 0.04.
Answer:
d: 21%
Step-by-step explanation:
1. add 180+135+105+80=500 total
2. then find the percent of 105 from 500 (Determine the total or whole amount.
Divide the number to be expressed as a percent by the total. In most cases, you'll divide the smaller number by the larger number.
Multiple the resulting value by 100.)
you get an answer of 21%
