Pencils come in packages of 20 and signs come in packages of 12 she wants to buy the same number of pencils and pens what is the least number of pencil and pen she needs to buy
Answers
Performing LCM, the least number of pencils and pens that she needs to buy are 60 pencils and 60 pens.
LCM refers to the least common multiple. The LCM of two or more numbers is the one that can divide all the numbers by the single number itself.
Pencils come in packages of 20 and pens come in packages of 12.
So, the possible lowest common multiplier is LCM of 20 and 12, and it is 60.
So she has to buy 3 packages of pencils (60/20 = 3 ) as well 5 packages of pens ( 60/12 = 5 ).

Can someone help me solve this question? | x-9 | +7 = 8
Answers
Answer:
x = 8
x = 10
Step-by-step explanation:
lx -9l + 7 = 8
lx - 9l + 7 - 7 = 8 - 7
lx - 9l = 1
Split into a positive and a negative case.
x - 9 = 1 and - (x - 9) = 1
Add nine to both sides
x - 9 + 9 = 1 + 9
x = 10
- (x - 9) = 1
Subtract 9 from both sides
- 8 = - x
Multiply both sides by negative 1
x = 8
A new concrete courtyard will be 15' by 25' and will be filled to a depth of 3" (1/4 foot.) How many cubic yards, rounded to the nearest tenth, of concrete do you need?
Answers
The volume in cubic yards of concrete needed is 3.5 cubic yards
Calculating volumeFrom the question, we are to calculate the volume of concrete needed
From the given information,
A new concrete courtyard will be 15' by 25'
That is,
15 feet by 25 feet
Also, from the given information,
The concrete will be filled to a depth of 3" (1/4 foot.)
That is, 0.25 foot
First, we will convert the measurements to yards
NOTE: 1 foot = 1/3 yards
Thus,
15 feet = 15/3 yards = 5 yards
25 feet = 25/3 yards
0.25 foot = 0.25/3 yard = 1/12 yards
Thus,
Volume of concrete needed = 5 × 25/3 × 1/12
Volume of concrete needed = 125/36
Volume of concrete needed = 3.472 cubic yards
Volume of concrete needed ≈ 3.5 cubic yards
Hence, the volume in cubic yards of concrete needed is 3.5 cubic yards

If a cantaloupe that weighs 3.0 pounds costs $3.87, approximately how much will a 2.22 pound cantaloupe cost?
Answers
Answer:[tex]1.29 * 2.22 = 2.86[/tex]
$2.86
Step-by-step explanation:
First we need to find the price per pound for the cantaloupe
[tex]3.87/3.0=1.29[/tex]
So one pound of cantaloupe costs $1.29
Now multiply the price per pound by the weight of the second cantaloupe
[tex]1.29*2.22=2.86[/tex]
So the price for a cantaloupe that weighs 2.22 lbs would be $2.86
certain disease has an incidence rate of 0.1%. if the false negative rate is 8% and the false positive rate is 1%, compute the probability that a person who tests positive actually has the disease.
Answers
The probability that a person who tests positive is infected is 0.0843.
Suppose the incident rate of a certain disease is 0.1 %.
The false negative rate is 8 % and the false positive rate is 1 %.
For a population of 100,00
There are 0.1 % infected = 100,00 × 0.1 % = 100
The population that is not infected is:
= 100,000 - 100 = 99900
The false negative rate is 8%, so the positive rate is 100 = 8 = 92%.
The population that is infected and has a positive result is:
= 100 × 0.92 = 92
The false positive rate is 1%.
The population that is not infected but has a positive result is:
= 99900 × 0.01 = 999
Therefore, the total positive results are:
= 92 + 999 = 1091
Therefore, the probability that a person who tests positive actually is infected is:
P ( infected / positive) = 92 / 1091 = 0.0843
Hence, the probability that a person who tests positive is infected is 0.0843.
