Quadrilateral Practice Test, I’ll give brainliest to the correct answer with explanation
Answers
Answer:
120 Degrees
Step-by-step explanation:
Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations
subtract 31x from both sides to get -4 = -2x + 4
Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

Which expression is NOT equivalent to −6×(13+13)? −63+13 −6×23 −6×(2×13) (13+13)×(−6)

I know that -63+13= -50
(-6) * 23 = (-138) are NOT equivalent, the only expressions that are equivalent are (13+13)x(-6) and -6x(2x13) they both equal to -156 which is to say -6x(13+13) Are the same

Select all the correct answers. Annie transforms the graph of y = 2x into the graph of y= 2x - 4. Which statements correctly describe this transformation?
Answer- Plato; It is the graph of y=2x translated 4 units downward. & It is the graph of y=2x translated 2 units to the right.
Answers
Answer:
It is the graph of y=2x translated 4 units downward
Step-by-step explanation:
Given
[tex]y = 2x[/tex] to [tex]y' = 2x - 4[/tex]
Required
We have:
[tex]y = 2x[/tex]
Subtract 4 from both sides [In other words, shift downward by 4 units]
[tex]y - 4 = 2x - 4[/tex]
This implies that:
[tex]y' = y -4[/tex]
Substitute [tex]y = 2x[/tex]
[tex]y' = 2x -4[/tex]
Answer:
It is the graph of y = 2x translated 4 units downward.
It is the graph of y = 2x translated 2 units to the right.
Step-by-step explanation:
Recall that f(x) − k is a vertical translation that translates f(x) down k units. And, a vertical translation also translates a function horizontally, and vice versa. So, y = 2x − 4 translates the function y = 2x down 4 units. But 2x − 4 is also equal to 2(x − 2), so y = 2x − 4 also describes a translation to the right by 2 units.

The graph of a twice differential function is shown at right. Which of the following is true?
Answers
Answer:
(C)
Step-by-step explanation:
looking from the slope: f'(2) is negative
f(2)=0
the curve concave upward: f''(2) is positive
f'(2)<0
f(2)=0
0<f''(2)
f'(2)<0<f''(2)
The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.
What is a differential function?A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
Given:
The coordinate of the graph is shown in figure (2, 0),
As we can see from the graph, the slope: f' (2) is negative (Downwards)
Again, from the graph
f(2) = 0
Thus, the curve concave upward: f'' (2) is positive (upward)
f' (2)<0
f (2)=0
0 < f'' (2)
f' (2) < 0 < f'' (2)
Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

Assume that 5 people, including the husband and wife pair, apply for 4 sales positions. People are hired at random.
(1) What is the probability that both the husband and wife are hired?
(2) What is the probability that one is hired and one is not?
Answers
Answer:
a) 0.2 = 20% probability that both the husband and wife are hired
b) 0.4 = 40% probability that one is hired and one is not
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the people are chosen is not important, which means that we use the combinations formula to solve this question.
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]
(1) What is the probability that both the husband and wife are hired?
Desired outcomes:
Both selected, only one possible outcome, so [tex]D = 1[/tex]
Total outcomes:
4 from a set of 5. So
[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{1}{5} = 0.2[/tex]
0.2 = 20% probability that both the husband and wife are hired
(2) What is the probability that one is hired and one is not?
Desired outcomes:
One selected, one not, so two possible outcomes(Wife yes, husband not, or husband yes and wife not). So [tex]D = 2[/tex]
Total outcomes:
4 from a set of 5. So
[tex]T = C_{5,4} = \frac{5!}{4!1!} = 5[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{2}{5} = 0.4[/tex]
0.4 = 40% probability that one is hired and one is not
