What is the difference ? X/x^2-2x-15-4/x^2+2x-35

lara31 [8.8K]

x / x² - 2x - 15 - 4 / x² + 2x - 35

FIND THE FACTOR OF EACH DENOMINATOR

= x / (x-5)(x+3)

- 4 / (x-5) (x+7)

FIND THE LCD AND MULTIPLY EACH TERM TO ARRIVE AT THE SAME DENOMINATOR.

= x / (x-5)(x+3) *

(x+7) / (x+7) - 4 / (x-5) (x+7) * (x+3)/(x+3)

PERFORM SUBTRACTION

= x2 + 7x / (x-5) (x+3) (x+7) - (4x + 12) / (x-5) (x+7) (x+3)

= x2 + 7x – 4x – 12 / (x-5) (x+3) (x+7)

this would be your answer = x² + 3x – 12 / (x-5) (x+3) (x+7)

Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70

-BARSIC- [3]

Answer:

The experimental probability of landing on heads is 0.3

Step-by-step explanation:

We are given the following in the question:

Number of heads = 30

Number of tails = 70

Talia said the probability of getting heads is $\frac{30}{70}$ .

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

$\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

Probability of heads =

$P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3$

The experimental probability of landing on heads is 0.3
