jacob is going shopping he finds a great deal on a laptop foe 40% off the original price if the sale price is $525 what is the o

aleksley [76]

Answer:

<u>The original price of the laptop was US$ 875</u>

Step-by-step explanation:

1. Let's review all the information given for solving this question:

Sale price of the laptop = US$ 525

Discount from the original price = 40%

2. Let's find the original price of the laptop

Original price of the laptop = x

Sale price of the laptop = US$ 525

Sale price of the laptop = x - 40%x

525 = x - 0.4x

525 = x - 4x/10 (0.4 = 4/10)

5,250 = 10x -4x (Multiplying by 10 at both sides)

5,250 = 6x

5,250/6 = 6x/6 (Dividing by 6 at both sides)

875 = 6

<u>The original price of the laptop was US$ 875</u>

According to a survey, 67% of murders committed last year were cleared by arrest or exceptional means. Fifty murders committed

Mrac [35]

Answer:

a) P(X=41)= 0.0086 = 0.86%

b) P(36≤X≤38)== 0.1215 = 12.15%

c) would be unusual that fewer that 20 murders were cleared because P(X≤20) = 0.000081 =0.0081%

Step-by-step explanation:

if the random variable X= number of cleared murders , then X follows a binomial distribution:

P(X=x)= n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)

where P(X=x)= probability of x cleared murders, n= number of murders selected=50 , p= probability for a murder to be cleared (67%)

therefore

a) P(X=41)=50!/[(50-41)!*41!]*0.67^41*0.33^(50-41)= 0.0086

b) P(36≤X≤38)= P(X≤38) - P(X≤36) = 0.9371- 0.8156 = 0.1215

c) P(X≤20) = 0.000081

therefore would be unusual that fewer that 20 murders were cleared

Lulu wants to get fit. She started with 50 laps a day and she intends to add 10 laps every week. Write a mathematical expression

Bumek [7]

The mathematical expression for the given statement is 50 + 10x

<h3>How to write a mathematical expression for this statement?</h3>

The given parameters are:

Initial distance = 50 laps

Rate of increment = 10 laps each week

Represent the number of weeks with x

So, we have:

Number of laps = Initial distance + Rate of increment * Number of weeks

This gives

Number of laps = 50 + 10 * x

Evaluate

Number of laps = 50 + 10x

Hence, the mathematical expression for the given statement is 50 + 10x
