PLEASE HELPPPPPfind The Value Of X.

Answers

Answer 1
the answer is x=21.

since the equations are both on one side, the sum of the equations will be 180.

5x-17+2x+50=180
add the like variables.
7x+33=180
subtract 33 from 180.
7x=147
divide 147 by 7.
x=21
*to check your answer sub in 21 where the x is and the two answers together and you should get 180*
hope this helps!!

Kepa has the flu, and he is concerned that he will not pass the mathematics exam. If the following three statements are true, will Kepa pass the exam?
i) Kepa will not fail the mathematics exam if he finishes his computer program.
ii) If he goes to the theatre, he does not have the flu.
iii) If he does not go to the theatre, he will finish his computer program

Answers

Answer:

Yes

Step-by-step explanation:

II is already false because Kepa can only go to the theatre if he doesn't have the flu. However, he does, so he cannot go. Then, if Kepa cannot go to the theatre, he will have to finish his computer program. Lastly, if the computer program is finished, Kepa will at least pass the exam.

Answer:

yes, if the computer program he will pass. he shouldn't go to the theatre if he has the flu or not cause hes been sick either way.

Here is a 95% confidence interval estimate of the proportion of adults who say that the law goes easy on celebrities: 0.692 < p < 0.748 (based on data from a Rasmussen Reports survey). a.What is the best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities

Answers

Answer:

The best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities is 0.72.

Step-by-step explanation:

Confidence interval concepts:

A confidence interval has two bounds, a lower bound and an upper bound.

A confidence interval is symmetric, which means that the point estimate used(best point estimate) is the mid point between these two bounds, that is, the mean of the two bounds.

In this question:

The two bounds are 0.692 and 0.748.

a.What is the best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities.

The mean of the bounds, so:

(0.692+0.748)/2 = 0.72

The best point estimate of the proportion of adults in the population who say that the law goes easy on celebrities is 0.72.

Six scatterplots are shown. Suppose regression lines were generated for them, then order their correlation coefficients from least to greatest.
A) C, D, B, A, E, F
B) F, E, D, C, B, A
C) C, B, D, E, A, F
D) A, B, C, D, E, F

Answers

Answer:

C) C, B, D, E, A, F

Step-by-step explanation:

The closer the data points are to each other along the line of best fit on a scatter plot, the greater the correlation coefficient and vice versa.

Therefore, the scatter plot that has the least correlation coefficient would be the scatter plot with the data points that are farther apart from each other along the line of best fit which is C, followed by B, D, E, A, and F.

Answer:

Hello Love! The median is simply just the number in the middle so sense we have 2 numbers in the middle our median will be 3 and 6

The mean is when you add up the numebers then divide by how many numbers there are so...

3 + 2 + 4 + 6 + 3 + 6 + 1 + 2 + 5 + 4 = 36 so 36 divided by 10 is 3.6

The range is simply just the biggest number in the sequence subtracted by the smallest number so... 6 - 1 = 5 so 5 would be our range!

Hope this helps you.

Jason drew a triangle to explain the Triangle Sum Theorem and labeled the angles 1, 2, and 3

He tore each angle off the triangle so he could move the three angles around.

What should Jason do next to explain the Triangle Sum Theorem?

Jason should line up the angles next to each other as adjacent angles to show that the 3 angles together form a straight angle.

Jason should create a new triangle by moving the angles closer together to show that the 3 angles can create other triangles.

Jason should fold each angle in half to show each angle with one half of the measure it had in the triangle.

Jason should stack the angles on top of each other to show that the 3 angles have the same measures.

Answers

Answer:

A

Step-by-step explanation:

Well B is strange. You might get them to make one complementary angle, but that has nothing to do with the Triangle sum theorem.

C is true. He is getting similar triangles, but that does not prove the Triangle sum theorem.  So -- don't choose C

D is just taking up space so you get 4 choices.

The answer should be A but the problem is the tips of the angles should all come to the same place. I think it does mean A, but it is a bit awkwardly worded.

Need help take your time and thx What then is the thematic relationship between her act and the painting on the wall behind her?The young woman standing before a table in a corner of a room gazes toward a balance held gently in her right hand. As though waiting for the delicate modulations of the balance to come to rest, she stands transfixed in a moment of equilibrium. She is dressed in a blue morning jacket bordered with white fur; seen through the parting of her jacket are vivid stripes of yellow and orange, perhaps ribbons or part of her bodice. Her white cap falls loosely to either side of her neck, framing her pensive yet serene face. Diffused sunlight, entering through an open window before her, helps illuminate the scene. The light, warmed by the orange curtain before the window, flows across the gray wall and catches the fingers of her right hand and the balance before resting on her upper figure. Behind the woman looms a painting of the Last Judgment * which acts as a compositional and iconographic foil to the scene before it. The Last Judgment, its proportions echoing those of the overall painting, occupies the entire upper right quadrant of the composition. Its rectangular shape establishes a quiet and stable framework against which Vermeer juxtaposes the figure of the woman. The woman's white cap and blue morning jacket contrast with the dark painting. Her figure is aligned with the central axis of the Last Judgment. Her head lies at the middle of its composition, directly beneath the oval mandorla of the Christ in majesty. Her right hand coincides with the lower corner of the frame, which happens also to be the vanishing point of the perspective system. Her head and the central gesture of her hand are thus visually locked in space, and a seeming moment of quiet contemplation becomes endowed with permanence and symbolic associations. The visual juxtaposition of the woman and the Last Judgment is reinforced by thematic parallels: to judge is to weigh. Christ, his arms and hands raised, sits in majesty on the day of judgment. His gesture, with both arms raised, mirrors the opposing direction of the woman's balance. His judgments are eternal; hers are temporal. Nevertheless, the woman's pensive response to the balance she holds suggests that her act of judgment, although different in consequence, is as conscientiously considered as that of the Christ behind her.
