PLZ HELP !!!!!!!Solve for the value of x and y
68
(4x - 2)
30
Answers
Answer: 10
Step-by-step explanation:
Simplifying
68 = 4x + -2 + 30
Reorder the terms:
68 = -2 + 30 + 4x
Combine like terms: -2 + 30 = 28
68 = 28 + 4x
Solving
68 = 28 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
68 + -4x = 28 + 4x + -4x
Combine like terms: 4x + -4x = 0
68 + -4x = 28 + 0
68 + -4x = 28
Add '-68' to each side of the equation.
68 + -68 + -4x = 28 + -68
Combine like terms: 68 + -68 = 0
0 + -4x = 28 + -68
-4x = 28 + -68
Combine like terms: 28 + -68 = -40
-4x = -40
Divide each side by '-4'.
x = 10
Simplifying
x = 10
Answer:
x = 10, y = 112
Step-by-step explanation:
4x - 2 + 30 and 68 are vertical angles and are congruent , then
4x - 2 + 30 = 68
4x + 28 = 68 ( subtract 28 from both sides )
4x = 40 ( divide both sides by 4 )
x = 10
------------------------
y and 68 lie on a straight line and sum to 180° , then
y + 68 = 180 ( subtract 68 from both sides )
y = 112

Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time. a. What kind of a distribution does X have (name and values of all parameters)
Answers
Answer:
X has an hypergeometric distribution, with parameters:
Size of the population is N = 18.
Size of the sample is n = 6.
Number of successes n is k = 8.
Step-by-step explanation:
The people are chosen without replacement, which means that the hypergeometric distribution is used.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time.
This means that [tex]N = 18, k = 8[/tex]
We consider a success being a person taking the test for the first time, because X is the number among the six who are taking the test for the first time.
Suppose that six of these individuals are randomly assigned to a particular examiner.
This means that [tex]n = 6[/tex]

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
O y=-5/2x-1
O y= -5/2x+ 5
O y=2/5x-1
O y=2/5x+5
Answers
Answer:
[tex]y = -\frac{5}{2}x-1[/tex]
Step-by-step explanation:
5x + 2y = 12
2y = -5x + 12
[tex]y = -\frac{5}{2}x +6[/tex]
Parallel lines have the same slope so the -5/2 remains. Just remove the b value (6) and plug in (-2,4) to the x and y spots.
[tex](4) = -\frac{5}{2}(-2) + b[/tex]
4 = 5 + b
b = -1
The new equation is [tex]y = -\frac{5}{2}x-1[/tex]

Answers
Point R and S cannot be the same point
The statement is false.
What is Circumcenter?The intersection of the perpendicular bisectors of a triangle's sides is known as the circumcenter of that particular triangle. In other terms, the circumcenter is the point at which the bisector of a triangle's sides coincides.
Given:
ΔPQR and ΔPQS both have same circumcenter named C.
As, both triangles have point P and Q same but S and R are different.
There many chances that they do not overlap or Coincide, they can be sharing same base but different vertex.
Hence, R and S cannot be the same point.

Let the recommended amount is x.
ATQ,
A grilled chicken salad at a popular fast food restaurant contains 650 mg of sodium which is 27% of recommended daily amount.
Mathematically,
[tex]27\%\ of\ x=650 \\\\\dfrac{27}{100}x=650\\\\x=\dfrac{650\times 100}{227}\\\\x=286.34\ mg[/tex]
