Find the experimental probability that exactly 3 of 4
otez555 [7]

Answer:

4 / 20 (1 / 5)

20%

Step-by-step explanation:

The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).

In this experiment, there are 3 outcomes with :

3 tails and 1 head

(tails represent female, head represent male)

So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)

4 / 20 = 20% of the time

So, the probability of a group of 4 puppies being 3 females and 1 male is :

4 / 20 (1 / 5)

20%

Morgan made a mistake when subtracting the rational expressions below.
Nat2105 [25]

Answer : D

\frac{3t^2-4t+1}{t+3} - \frac{t^2+2t+2}{t+3}

The denominators are  same

So we combine the numerators

\frac{(3t^2-4t+1)-(t^2+2t+2)}{t+3}

To remove parenthesis we distribute negative sign inside the second parenthesis

\frac{3t^2-4t+1-t^2-2t-2)}{t+3}

\frac{3t^2-4t+1-t^2-2t-2)}{t+3}

\frac{2t^2-6t-1)}{t+3}

Morgan made a mistake. He forgot to distribute the negative sign

Morgan forgot to distribute the negative sign to two of the terms 2t  and 2 inside second parenthesis

Analyze the diagram below and complete the instructions that follow.
Trava [24]

Law of Cosines says


b^2 = a^2 + c^2 - 2 ac \cos B


2 a c \cos B = a^2 + c^2 - b^2


\cos B = \dfrac{a^2 + c^2 - b^2}{2 a c}


\cos B = \dfrac{16^2 + 16^2 - 11^2}{2(16)(16)} = \dfrac{ 391}{512}


B = \arccos  \dfrac{ 391}{512} \approx 40.2 ^\circ
