In the given question, there are numerous information's already provided. It is important to note then down first. With the help of those given information's the required answer can be easily reached.
Percentage of students that weighed 140 pounds = 75 percent
Then
Percentage of students that weighed more than 140 pounds = (100 - 75) percent
= 25 percent
Total number of students that were weighed = 40 students
Total number of students that weighed more than 140 pounds = (25/100) * 40
= (40/4) students
= 10 students
So the number of students that weighed more than 140 pounds is 10. So the correct option in regards to the given question is option "1".
Answer:

Step-by-step explanation:
The graph you see there is called a parabola. The general equation for the graph is as below

To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.
To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!

Awesome, we've found both values. And we can write the result.

I'll include a plotted graph with our equation just so you can verify it is indeed the same.

Sphere Formulas in terms of radius r:
Volume of a sphere: V = (4/3)πr.
(2/5) of (2/3) of students = 4/15 of students study French. Then 1-(4/15) = 11/15 of students do not study French. The ratio you want is
(4/15):(11/15) = 4:11

Marilyn's net pay will increase by $18.15 as her Federal Withholding Allowance increases from 3 to 4.
<h3>What is Federal Withholding Allowance?</h3>
A Federal Withholding Allowance is an exemption that lowers the amount of income tax you must deduct from an employee's paycheck.
Given: The following are the deductible computation:
- For federal withholding allowance = 3:
- Social Security Tax: 6.2% of $810 =
= $50.22 - Medicare tax : 1.45% of $810 =
= $11.745 - State tax: (21% of 3)% of $810=
= 0.63% of $810 =
= $5.103
Total = $67.068; deducted amount of his gross pay = $810 - $67.068 $742.932 (3 federal withholding).
- For Federal Withholding Allowance = 4:
- State tax: (21% of 4)% of $810 =
= 0.84% of $810 =
= $6.8704
Thus, as we can see from the calculations, the State taxes increased from $5.103 to $6.8704. Hence, the net pay increases by $18.15 as the federal allowance increases from 3 to 4.
