Answers

Answer 1

Answer:

Answer:

10x² - 9x

Step-by-step explanation:

(10x² - 10x - 6) + (x + 6)

10x² - 10x - 6 + x + 6

10x² - 9x - 6 + 6

10x² - 9x

Right or leftMost people are right-handed, and even the right eye is dominant for most people. Molecular biologists have suggested that late-stage human embryos tend to turn their heads to the right. In a study reported in Nature (2003), German bio-psychologist OnurGüntürkün conjectured that this tendency to turn to the right manifests itself in other ways as well, so he studied kissing couples to see which side they tended to lean their heads while kissing. He and his researchers observed kissing couples in public places such as airports, train stations, beaches, and parks. They were careful not to include couples who were holding objects such as luggage that might have affected which direction they turned. For each kissing couple observed, the researchers noted whether the couple leaned their heads to the right or to the left. They observed 124 couples, ages 13–70 years. Suppose that we want to use the data from this study to investigate whether kissing couples tend to lean their heads right more often than would happen by random chance.The symbol π represents the long-run proportion of all the couples that lean their headsleftrightwhile kissing.Which of the following best describes the null hypothesis and the alternative hypothesis using π?null: π ≠ 0.5, alternative: π > 0.5null: π = 0.5, alternative: π < 0.5null: π = 0.5, alternative: π > 0.5null: π ≠ 0.5, alternative: π < 0.5Of the 124 kissing couples, 80 were observed to lean their heads right. What is the observed proportion of kissing couples who leaned their heads to the right? What symbol should you use to represent this value? (Round answer to 3 decimal places, e.g. 5.275)p^=the absolute tolerance is +/-0.001Determine the standardized statistic from the data. (Hint: You will need to get the standard deviation of the simulated statistics from the null distribution.) (Round answer to 2 decimal places, e.g. 52.75)z = the absolute tolerance is +/-0.02Interpret the meaning of the standardized statistic.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations above the null hypothesized value of 0.50.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations away from the null hypothesized value of 0.50.The observed proportion of couples who leaned to the right when kissing is 3.22 standard deviations below the null hypothesized value of 0.50.Select the best conclusion that you would draw about the null and alternate hypotheses.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is more than 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is less than 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is 50%.We have strong evidence that the proportion of couples that lean their heads to the right while kissing is near to 50%.

C is correct

Step-by-step explanation:

Answer:

Step-by-step explanation:

Angle L is an obtuse angle, as all angles in an equilateral pentagon are obtuse.

Also, all other statements are false:

A) The two lines are not parallel, as they would eventually intersect

B) This angle is not acute, as it is more than 90 degrees

D) These lines are not perp., as they do not form right angles at their intersection

So your answer is C! Hope it helps!

Find the indicated probability. a bag contains four chips of different colors, including red, blue, green, and yellow. a chip is selected at random from the bag and then replaced in the bag. a second chip is then selected at random. make a list of the possible outcomes (for example rb represents the outcome red chip followed by blue chip) and use your list to determine the probability that the two chips selected are the same color. (hint: there are 16 possible outcomes.)

Answers

Answer:

0.25

Step-by-step explanation:

Let

r = red

b = blue

g = green

y = yellow

If the first chip is r, the second can be r, b, g or y. The 4 possibilities are rr, rb, rg, ry.
If the first chip is b, the second can be r, b, g or y. The 4 possibilities are br, bb, bg, by.

If the first chip is g, the second can be r, b, g or y. The 4 possibilities are gr, gb, gg, gy.

If the first chip is y, the second can be r, b, g or y. The 4 possibilities are yr, yb, yg, yy.

From the 4 + 4 + 4 + 4 = 16 possible outcomes, there are 4 in which the chips are of the same color (rr, bb, gg, yy). The probability that the two chips selected are the same color is

4/16 = 0.25 = 25%
