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.

Multiply the binomials (x + 1)(-5x + 10) *

Leona [35]

So i think here you would FOIL. so -5x^2+10x-5x+10 and then combine like terms :)

The test to detect the presence of a certain protein is 98% accurate for corn plants that have the protein and 97% accurate for

larisa [96]

Using the given percentages, it is found that the probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.

<h3>Percentages:</h3>

The percentages associated with an incorrect detection are:

2% of 3.5%(have the protein).

3% of 96.5%(do not have the protein).

Hence:

$p = 0.02(0.035) + 0.03(0.965) = 0.02965$

The probability that a randomly chosen plant is detected incorrectly is 0.02965 = 2.965%.
