Let x=peter's age
let 3x=bob's age
3x+x=56
4x=56
x=14
3(14)=42
Bob is 42 years old.
Answer:
the Total cost= 1,200,000*number of states
Step-by-step explanation:
Given the cost of each home is $80,000
The number of homes per state are 15
The Total cost of the project is = (Total number of houses per state) * (cost of each house) * (the number of states).
Therefore the total cost =15*80000*Number of states.=1,200,000*number of states
The last one is the answer
Answer:
The percentage of admitted applicants who had a Math SAT of 700 or more is 48.48%.
Step-by-step explanation:
The Bayes' theorem is used to determine the conditional probability of an event <em>E</em>, belonging to the sample space S = (E₁, E₂, E₃,...Eₙ) given that another event <em>A</em> has already occurred by the formula:
Denote the events as follows:
<em>X</em> = an student with a Math SAT of 700 or more applied for the college
<em>Y</em> = an applicant with a Math SAT of 700 or more was admitted
<em>Z</em> = an applicant with a Math SAT of less than 700 was admitted
The information provided is:
Compute the value of as follows:
Compute the value of P (Y|X) as follows:
Thus, the percentage of admitted applicants who had a Math SAT of 700 or more is 48.48%.
a easy way to remember how to divide is KCF Keep the first fraction Change the division to multiplication and Flip the second fraction. 1/2*8/1 =8/2 =4
