Hey there!

b^2 + 5b - 5

= -6^2 + 5(-6) - 5

= -36 + (-30) - 5

= -66 - 5

= -71

Therefore, your answer is: -71

Good luck on your assignment and enjoy your day!

Bill's golf bag contains 9 white golf balls, 6 yellow golf balls, 1 orange golf ball, and 1 pink golf ball. Without looking, Tim
BaLLatris [955]

Answer:

The correct answer is 0.0330 and the events are independent.

Step-by-step explanation:

Total number of balls in Bill's golf bag = 17

Let A be the event of drawing a white ball and B be the event of drawing an orange ball.

Number of white balls Bill has in his bag is 9.

Probability of the event A in the first draw = \frac{9}{17}

Number of orange ball in Bill's bag is 1.

Probability of event B in the second draw = \frac{1}{16}

Thus total probability for Tim to tee off with a white ball and putt with an orange ball = \frac{9}{272} = 0.0330

The above events are independent on each other.

Suppose a box contains 3 defective light bulbs and 12 good bulbs. two bulbs are chosen from the box without replacement. find th
Mademuasel [1]
The probability that the bulb is good is 12/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective bulb is now 3/14.
Now you multiply the probabilities together to get (12/15)(3/14)=(4/5)(3/14)=12/70=6/35

To investigate if there is an association between eating red meat and the health of individuals, researchers used data from a na
Reika [66]

Answer:

a) Observational study

b) No

c) No

-Eating habits

-Age

-Health hystory

Step-by-step explanation:

Hello!

An observational study is one where the investigator has no control or intervenes on it. He just defines the variable of interest and merely collects and documents the information. These types of studies are usually made as precursors to a more formal experimental study, to have an idea of what's to be expected from the population.

In this example, the researcher merely took the information of interest from the survey that was taken. The researcher did not intervene in any way in the experiment. Because of the lack of intervention from the researcher, it is not valid to use the conclusions of this experiment to generalize to all American adults. For instance, it is not sure that the sample is representative, all people responding to the survey may be healthy or have certain eating habits. This also shows that many confusing factors are not taken into account like:

-eating habits (from eating healthy to extreme cases like being vegetarian/vegan or eating only fast food)

-age, the age range is not defined, if the sample is taken from surveys answered by people in their early 20s it will be different in both eating habits and health information as if the interviewees are in their 30s or 40s

-before health issues, there can be other health conditions that may be affecting the interviewees.

I hope it helps!
