Answer:
31
Step-by-step explanation:
2 out of 35 are chess club members.
The fraction of chess club members in the survey is 2/35.
Now we find 2/35 of 550.
2/35 * 550 = 1100/35 = 31.43
Answer: 31
If there are 550 students at her school, then there are 31 chess club members in the entire school.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
If Carmen surveyed a random sample of 35 students and found that 2 are chess club members.
We can set up a proportion to solve for this:
2/35 = x/550
where x is the number of chess club members in the entire school.
To solve for x, we can cross-multiply and simplify:
2 × 550 = 35 × x
1100 = 35x
Divide both sides by 35.
x = 1100/35
x ≈ 31.43
Therefore, we can estimate that there are approximately 31 chess club members in the entire school.

Jazzmine took out a loan of $17,500 to buy a new car. She received a 3.5% interest rate compounded annually and paid $3,274.50 in interest. How long did it take Jazzmine to pay off the loan?
Answer:
Time period = 5 year (Approx.)
Step-by-step explanation:
Given:
Amount of loan = $17,500
Rate of interest = 3.5% compounded annually
Amount paid as interest = $3,247.5
Find:
Time period
Computation:
Using compounded interest formula
I = P[(1+r)ⁿ - 1]
3,247.50 = 17,500[(1+3.5%)ⁿ - 1]
3,247.50 = 17,500[(1+0.035)ⁿ - 1]
3,247.50 = 17,500[(1.035)ⁿ - 1]
Time period = 4.948
Time period = 5 year (Approx.)

Step-by-step explanation:
The given equation is :
[tex]PV=nrT[/tex]
Where
P is pressure
V is volume
n is no of moles
r is Gas constant
T is temperature
We need to solve the above equation for r.
Dividing both sides of the above equation by (nT). So,
[tex]\dfrac{PV}{nT}=\dfrac{nrT}{nT}\\\\r=\dfrac{PV}{nT}[/tex]
So, the value of r is equal to [tex]\dfrac{PV}{nT}[/tex].

Step-by-step explanation:
25 - (9 - y) = 20.7
Putting value of y = 4.3 in equation
25 - (9 - 4.3) = 20.7
25 - 4.7 = 20.7
20.3 = 20.7
Bringing like terms on one side
20.7 - 20.3 = 0.4
Answer; in this question we should have to put the value of y=4.3 and then we will get the answer.
Step-by-step explanation:
25-(9-y)=20.7
25-(9-4.3)=20.7
25-(4.7)=20.7
20.3=20.7
Bring the term on one side
20.7-20.3=0.4 Answer
Find the area of the square or rectangle write your answer as a fraction
The solution is, the area of the square is 4/9 in^2.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object. Area of a square (A) is the product of its length (l) and width (l).
i.e. A= l× l
here, we have,
In this problem we have a square
so
the area of a square is
A=b^2
we have
b=2/3 in
substitute
A=(2/3)^2
A=4/9 in^2
Hence, The solution is, the area of the square is 4/9 in^2.

What is the surface area of a right circular cylindrical oil can, if the radius of its base is 4 inches and its height is 11 inches? for 25 points
Step-by-step explanation:
Given
Radius (r) = 4 inches
height (h) = 11 inches
Total surface area of cylindrical oil can is
= 2πr ( r + h)
= 2 * 22 / 7 * 4 ( 4 + 11)
= 2 * 22/7 * 4 * 15
= 377.14 inches ²
If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.
What is the surface area of a right circular cylindrical figure?Let b and h be the radius of the base and height of a right circular cylindrical figure respectively. Then the surface area of this right circular cylindrical figure is 2πb(b + h).
How to solve this problem?Given that the radius of the base of the can is 4 inches.
The height of the can is 11 inches.
Then the surface area of the can = 2π * 4(4 + 11) = 8π(15) = 120π = 376.99 square inches
Therefore, If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.
