Complete question :
In a class of 125 students, 27 are computer science majors, 51 are mechanical engineering majors, 12 are civil engineers and the rest are general engineering majors. Assume students only have one major.
Suppose six students from the class are chosen at random what is the probability none are mechanical engineering majors?
Answer:
0.039
Step-by-step explanation:
Total = T = 125
Computer Science = S = 27
Mechanical Engineering = M = 51
Civil Engineering = C = 12
General engineering, G = 125 - (27 + 51 + 12) = 35
Probability that none out of six chosen at random are Mechanical Engineering major :
Probability = required outcome / Total possible outcomes
Non mechanical engineering majors = 125 - 51 = 74
Probability none of 6 selected are mechanical engineering majors :
74C6 / 125C6
Recall :
nCr = n! / (n-r)! r!
, using calculator :
74C6 / 125C6 = 185250786 / 4690625500
= 0.0394938
= 0.039

A store sells an item for $35 after a 25% markup. What is the price the store paid?
Answer:
43.75
Step-by-step explanation:
25 divided by 100=.25
.25*35=8.75
8.75+35=43.75
The store paid a price of $28 for the item.
What is Mark up Percentage?Mark up percentage is the percentage of profit on a certain service or commodity.
We know the formula to calculate mark up percentage.
Mark up Percentage = [(Selling price - Cost) / cost] × 100
Here, given that,
Mark up percentage = 25%
Selling price = $35
We have to find the cost.
Let x be the price that the store paid for the item.
Substitute the given values in the formula for mark up percentage.
25 = [(35 - x) / x] × 100
Dividing both sides of the equation by 100,
25/100 = (35 - x) / x
0.25 = (35 - x) / x
Multiplying both sides with x,
0.25x = 35 - x
Adding both sides with x,
0.25x + x = 35
1.25x = 35
Dividing both sides by 1.25,
x = 35 / 1.25
x = 28
Hence the price of the item that the store paid is $28.

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
Please see the picture
Help me
Test
Answer:
100.3 square units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of circle
Note: 2 semicircles = 1 full circle
Area of the figure = a*h + πr²
Where,
a = 10
h = 5
r = ½ of 8 = 4
Plug in the value into the equation
Area = 10*5 + π*4²
Area = 50 + π*16
Area = 100.265482 ≈ 100.3 square units (nearest tenth)

6x+4y=-6
2x+5y=9
Please help
Answer:
Step-by-step explanation:
Simplifying
6x + 4y = 6
Solving
6x + 4y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
6x + 4y + -4y = 6 + -4y
Combine like terms: 4y + -4y = 0
6x + 0 = 6 + -4y
6x = 6 + -4y
Divide each side by '6'.
x = 1 + -0.6666666667y
Simplifying
x = 1 + -0.6666666667ySimplifying
6x + 4y = 6
Solving
6x + 4y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4y' to each side of the equation.
6x + 4y + -4y = 6 + -4y
Combine like terms: 4y + -4y = 0
6x + 0 = 6 + -4y
6x = 6 + -4y
Divide each side by '6'.
x = 1 + -0.6666666667
Simplifying
x = 1 + -0.6666666667
Simplifying
2x + 5y = 9
Solving
2x + 5y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
2x + 5y + -5y = 9 + -5y
Combine like terms: 5y + -5y = 0
2x + 0 = 9 + -5y
2x = 9 + -5y
Divide each side by '2'.

Determine if the statement is true or false. Any linear system with more variables than equations cannot have a unique solution.
Answer:
True
Step-by-step explanation:
Suppose a system contains a large number of variables than equations, then there is a need to make assumptions of some values for the extra variables in order to solve the system. So, the assigning of these values can be done in several ways. Thus, the system cannot contain a unique solution.
Also, for a system of the linear equation:
[tex]AX = B[/tex] can have a unique solution if:
Augmented matrix(rank) = coefficient matrix(rank) = no. of variables.
Provided that there exist fewer equations and more variables,
Then;
coefficient matrix(rank) < no. of variables
Thus, the system cannot contain a unique solution.

Answer:
CED=126
Step-by-step explanation:
The total of all 3 angles should be 180
so:
180-38-16 (ABC is equal to ECD)
180-38-16=126
126=CED
Answer:
∠E= 126°
Step-by-step explanation:
the parallel lines create a transversal (the diagonal line that connects them)
this transversal rule shows us that
∠DCE=∠CBA
so ∠DCE= 38°
let's look at the triangle
∠C+∠D+∠E=180°
38+16+∠E= 180°
∠E= 126°
