Answer:

  1/10

Step-by-step explanation:

Apparently, a "trial" is a representation of a sample of 4 students. If the digits in that sample are 8 or 9, the students did not watch television. We can revise each of the trials by changing digits 0-7 to W, and digits 8-9 to N. (W = watched TV; N = did not watch TV.)

Now, the 10 trials are ...

  WWWW, WWWW, WWWW, WWWW,

  WWWW, WWWW, WWWW, NWWW, WWNW, NWNW

Of the 10 trials, 1 trial had the result that exactly 2 of the 4 watched TV.

The probability that exactly 2 of 4 watched TV is about 1/10 = 10%.

Priya and Han both factored the number 80. Priya says they should both get the same answer even if they started with different f
meriva

Answer:

Priya is right.

Step-by-step explanation:

The factors of 80 is 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

The factor pairs of 80 are

1 x 80, 2 x 40, 4 x 20, 5 x 16 and 8 x 10

If Priya picks 2 x 40, then it's prime factorisation will be, 2 x 2 x 2 x 2 x 5 = 2⁴ x 5.

If Han picks, 5 x 16 = 5 x 2 x 2 x 2 x 2 = 5 x 2⁴ = 2⁴ x 5. This is the same.

Therefore, Priya is correct, because the factors of 80 are always the same, therefore which ever you start with, you'd always get the same answer.

Answer:

86°

Step-by-step explanation:

180° is the sum of all angles in a triangle

The two angles given are 68° and 26°

The equation is : 180° - 68° - 26° = x°

180° - 68° - 26° = 86°

x° = 86°
