Answer:

We have to find the value of cosine for an angle with point ( 5, - 12 ) on its terminating side. First we have to find the hypotenuse ( Adjacent = 5, Opposite = 12 ) : c^2 = 5^2 + 12^2 = 25 + 144 = 169; c = sqrt(169 ), c = 13. Cosine for an angle = Adjacent / Hypotenuse = 5 / 13 = 0.385. Answer: The value of cosine is 5/13, Hope that helps!.

The answer would be Jenna's answer. If you distribute the teachers original expression you get 15x + 20y + 5. If you distribute Jenna's answer you get just that.

First photo question-The graph below shows three different normal distributions.

zheka24 [161]

Answer:

For the first question: They must each have a different mean and a different standard deviation. For the second question: In an observational study the researchers do not control treatment and in an experiment they do. For the third question: The second graph. For the fourth question: The second graph.

Step-by-step explanation:

For the first question: We can see that each bell-shaped curve is centered around a different number. This tells us that their means are all different.

We can also see that each curve has a different width; this means that the spread of data, measured in part by the standard deviation, is different as well. This means both the mean and the standard deviation of each distribution is different.

For the second question: In an observational study, as the name implies, all that is done is observation. There is no treatment given by the researchers. In an experiment, however, one group receives treatment and one group does not, so the differences can be measured.

For the third question: In the first graph, the probabilities add up to 1.2. This is more than 100%, so this is not a valid distribution. In the second graph, the probabilities add up to 1.0; this is 100% exactly, so this is a valid distribution.

For the fourth question: In the first graph, the probabilities only add up to 0.9. This is not 100%, so this is not a valid distribution. In the second graph, the probabilities add up to 1.0; this is 100% exactly, so this is a valid distribution.

find the approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 in

soldi70 [24.7K]

Answer:

The approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = 0.15866

Step-by-step explanation:

The complete question is presented in the attached image to this answer.

It is stated that the distribution of tree diameters is approximately normal, hence, this is a normal distribution problem with

Mean diameter = μ = 8 inches

Standard deviation = σ = 2.5 inches

The approximate probability that a randomly selected aspen tree in this park in 1975 would have a diameter less than 5.5 inches = P(x < 5.5)

To solve this, we first normalize or standardize 5.5 inches

The standardized score for 45mg/L is the value minus the mean then divided by the standard deviation.

z = (x - μ)/σ = (5.5 - 8)/2.5 = - 1.00

The required probability

P(x < 5.5) = P(z < -1.00)

We'll use data from the normal probability table for these probabilities

P(x < 5.5) = P(z < -1.00) = 0.15866

Hope this Helps!!!
