6) corresponding angles are equal. 45x=46x-2. -x=-2. x=2. 7) same side interior angles. add up to 180. x+140+x+60=180. 2x=-20. x=-10. 8) alternate exterior angles are equal. 16x+9=4+17x. -x=-5. x=5. 9) same side interior angles. add up to 180. 19x+1+9x+11=180. 28x=168. x=6.

In a group of a hundred and fifty students attending a youth workshop in mombasa, 125 of them are fluent in kiswahili, 135 in en

jek_recluse [69]

Answer:

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = 1.1

Step-by-step explanation:

Step(i):-

Given total number of students n(T) = 150

Given 125 of them are fluent in Swahili

Let 'S' be the event of fluent in Swahili language

n(S) = 125

The probability that the fluent in Swahili language

$P(S) = \frac{n(S)}{n(T)} = \frac{125}{150} = 0.8333$

Let 'E' be the event of fluent in English language

n(E) = 135

The probability that the fluent in English language

$P(E) = \frac{n(E)}{n(T)} = \frac{135}{150} = 0.9$

n(E∩S) = 95

The probability that the fluent in English and Swahili

$P(SnE) = \frac{n(SnE)}{n(T)} = \frac{95}{150} = 0.633$

Step(ii):-

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = P(S) + P(E) - P(S∩E)

= 0.833+0.9-0.633

= 1.1

Final answer:-

The probability that a student chosen at random is fluent in English or Swahili.

P(S∪E) = 1.1

2 and 4 seemed really confusing , please help :(

artcher [175]

2. This question is basically asking you to factor 6x² - x - 12, so that one bracket is (2x - 3) and the other bracket is your answer. If you do factor 6x² - x - 12, you get (2x - 3)(3x + 4), so your answer would be J. 3x + 4.

4. Again you are factoring, so you would get your answer as (x + 3)(x - 2), which is answer F.

I hope this helps! Let me know if you would like me to show you how I factored :)

jenyasd209 [6]

Answer:

The coordinates of the image of point A (2, -7) are A'(-1,-2).

Step-by-step explanation:

Note: The sign is missing between y and 5 in the rule of transitional.

Consider the rule of translation is

$(x,y)\Rightarrow (x-3,y+5)$
