Answer:
The answer is C (0.30) are NOT going to particulate
Step-by-step explanation:
We can find the answer by simply putting all of the results into order, which gives the following for the non-participants:
28: 6's
27: 7's
29: 8's
15: 9's
Now to find the answer, we must know the total amount of results, which I found to be 250. We also need to know the total amount of non-participants there are, which is 99. So if we take 99 and divide it by 250 (99/250); we get 0.396. Although this isn't the exact answer, it is the closest.
To further prove that this should be right, Yuri found 60% of students to participate, which leaves around 40% left to not participate. So this should be right.
Hope this helps! - SC

The take-home pay of Tyson after deduction of his obligations from total income equals to $28,524.
What is a take-home pay?
This means the net income that an individual takes home.
Take-home pay = Annual Salary - Federal Income Tax - FICA - Disability Insurance - Life Insurance
Take-home pay = $42,500 - $8,500 - $3,251 - $2,125 - $$100
Take-home pay = $28,524
Thus, the take-home pay of Tyson after deduction of his obligations from total income equals to $28,524.

Simplify 6 plus the square root of negative 80.
The given statement can be written as:
6+√-80
To solve √-80 re-write -80 as -1 * 80
Now √-80 =√-1 * 80
Now we can write it as:
6+ √-1 * √80
We know that √-1 = i
Thus it becomes:
6+ i√80
Now find the square root of 80
80 does not have a perfect square root
Its square root can be found as 80 = 4*4*5
Then,
6+i√4*4*5
Notice that 4 makes a pair.. So we will write it outside the square root
6+1*4√5
We will write it as:
6+4i√5
Thus the correct option is 6 plus 4 i times the square root of 5....
5. Find all the two-digit numbers which are increased by 75% when their digits are reversed.
Answer:
Let a two digit number be, 10x + y.
75% of the number is,
= 75 % of (10 x + y)
= 75/100 × (10x+y)
= 3/4 × ( 10x + y)
According to the question, When increased by 75%, The digits must be reversed.
So,
(10 x + y) + 3/4 ( 10x + y) = 10y + x
4 (10x + y) + 3 ( 10x + y) = 4 ( 10y + x)
7(10x + y) = 4(10y + x)
70x + 7y = 40y + 4x
70x - 4x = 40 y - 7y
66x = 33y
2x = y
So,
x = 1, y = 2, 10x + y = 12
x = 2, y = 4, 10x + y = 24
x = 3, y = 6, 10x + y = 36
x = 4 , y = 8 , 10x + y = 48
x can't be 5, as y will be 10 ( y should be a single digit).
Therefore, 4 two digit numbers are possible.

Thank you!
Can anyone please help me IM not sure if the first one is correct
Answer:
you are correct keep up the good work.
Answer:
The 1st one is correct and the second one is (5, -3)
Step-by-step explanation:
For the 1st question this is what I did:
d=√(x^2−x^1)^2+(y^2−y^1)^2
d=(0−4)^2+(6−3)^2
√d=(−4)^2+(3)^2
√d=16+9
√d=25
√d=5
For the second question I did this:
(xM,yM)=(x1+x2/2,y1+y2/2)
M=(xM,yM)
M=(x1+x2/2,y1+y2/2)
M=(3+7/2,−1+−5/2)
M=(10/2,−6/2)
M=(5,−3)

what is the measure of MOP Angle MON is a straight angle and OP bisects MOQ
The measure of the angle MOP is 61° (Third option)
What is an angle?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Angle MON is a straight angle → ∠MON=180°
∠QON=58° (according to the graph)
OP bisects angle ∠MOQ, then OP divides angle ∠MOQ into two equal angles:
∠MOP=∠POQ=∠MOQ/2 (1)
∠MOQ+∠QON=∠MON
Replacing the known values in the equation above:
∠MOQ+58°=180°
Solving for ∠MOQ: Subtracting 58° on both sides of the equation
∠MOQ+58°-58°=180°-58°
∠MOQ=122°
Replacing ∠MOQ by 122° in the equation (1)
(1) ∠MOP=∠POQ=122°/2
∠MOP=∠POQ=61°

How many yards are equivalent to 38 feet? 1 yard = 3 feet
Answer:
13 yards
Step-by-step explanation:
38/3 => 12.6667 yards which would be closest to 13 yards
The formula is to divide the lenght value by 3.
The number 38 feet is equal to 12.67 yards.
We have to give that,
To change 38 feet into yards.
Since we know that,
1 yard = 3 feet
1 feet = 1/3 yards
Hence, change 38 feet into yards as,

Sadie is 3 years older than Kareem, and Kareem is twice as old as Nadra. The sum of their ages is 33.
A student used the steps below to find each person’s age.
Step 1 Write an equation, letting x represent Kareem’s age:
(x + 3) + x + 2 x = 33
Step 2 Solve the equation:
(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 and one-half.
Step 3 Sadie is 10 and one-half, Kareem is 7 and one-half, and Nadra is 3 and three-fourths.
Which corrects the student’s first error?
Answer:
Step 1-Write an equation, letting x represent Kareem’s age:
(x + 3) + x + 2 x = 33
Step 2-Solve the equation:
(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.
Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.
Which corrects the student’s first error?
1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.
2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.
3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.
4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.
F(x,y) = 4 ; r is the region enclosed by the petal of a rose curve r = sin*2theta)
The area of the region enclosed by the petal of a rose curve r = sin2θ in the first quadrant is π/8 square units
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We know the area in the polar coordinates is given by:
[tex]\rm A =\int\limits^a_b {\dfrac{1}{2}r^2} \, d\theta[/tex]
We have r = sin2θ
Here the quadrant is not given, so we are assuming we need to find the area in the first quadrant.
Put this value in the above integration and limit 0 to π/2
[tex]\rm A =\int\limits^{\dfrac{\pi}{2}}_0 {\dfrac{1}{2}(sin^22\theta)} \, d\theta[/tex]
After solving the above integration, we get:
[tex]\rm A = \dfrac{\pi}{8}[/tex]
Thus, the area of the region enclosed by the petal of a rose curve r = sin2θ in the first quadrant is π/8 square units
