A landscaping company currently has an inventory of 8 fruit trees, 13 pine trees, and 14 maple trees. It plans to give 4 trees away at next
Saturday's lawn and garden show in the city park. The 4 winners can select which type of tree they want. Assume they select randomly.
a. What is the probability that all 4 winners will select the same type of tree?
b. What is the probability that 3 pine trees will be selected and the other tree will be a maple?
c. What is the probability that no fruit trees and 2 of each of the others will be selected?
a. The probability is
(Round to four decimal places as needed.)
The distribution of the trees in the landscape company is an illustration of probability
The probability that all 4 winners will select the same type of tree is 0.0341The probability that 3 pine trees will be selected and the other tree will be a maple is 0.0710The probability that no fruit trees and 2 of each of the others will be selected is 0.0904a. The probability that all 4 winners will select the same type of tree?The distribution of the trees are:
Fruit trees = 8Pine trees = 13Maple trees = 14Total = 8 + 13 + 14
Total = 35
The probability is then calculated as:
P(Same type) = P(All fruit trees) + P(All pine trees) + P(All maple trees)
So, we have:
P(Same type) = (8/35 * 7/34 * 6/33 * 5/32) + (13/35 * 12/34 * 11/33 * 10/32) + (14/35 * 13/34 * 12/33 * 11/32)
Evaluate
P(Same type) = 0.0341
Hence, the probability that all 4 winners will select the same type of tree is 0.0341
b. The probability that 3 pine trees will be selected and the other tree will be a maple?The probability is then calculated as:
P(3 pine and one maple) = 4 * P(Three maple and One Pine)
So, we have:
P(3 pine and one maple) = 4 * (13/35 * 12/34 * 11/33 * 13/32)
Evaluate
P(3 pine and one maple) = 0.0710
Hence, the probability that 3 pine trees will be selected and the other tree will be a maple is 0.0710
c. The probability that no fruit trees and 2 of each of the others will be selected?The probability is then calculated as:
P(2 pine and 2 maple) = 4 * P(Two pine and Two maple)
So, we have:
P(2 pine and 2 maple) = 4 * (13/35 * 12/34 * 14/33 * 13/32)
Evaluate
P(2 pine and 2 maple) = 0.0904
Hence, the probability that no fruit trees and 2 of each of the others will be selected is 0.0904

Its kind of basic, we know that swimming pools are exposed to sunlight, and gets heat. Thus, the water will get evaporated with time. And same is the case with Sarah's swimming pool. Thus the answer becomes :
☆ Evaporation is the reason why Sarah's father has to add water to the swimming pool every month. The water in the pool gets evaporated due to the exposure to sunlight and hence, the amount of water gets decreased. Thus, to maintain the same Sarah's father has to do the same.

A comparison between species: Biologists wish to compare the prevalence of a genetic mutation across
two species of Neema Toads. In a sample of 9 Neema Toads of Species I, 0.6% had the mutation while in a
sample of 12 Neema Toads of Species II, 1% showed the mutation. Is there significant evidence to suggest a
difference in the prevalence of the mutation across the two species? Conduct a hypothesis test at a
significance level of a = 0.01.
The result from the hypotheis test below shows that there is no significant evidence existing to show difference in the mutation.
How to solve for the z statisticsThe hypothesis for this test has been stated below:
H0: pI - pII = 0
Ha: pI - pII ≠ 0
n1 = 9
p1 = 0.6%
n2 = 12
p2 = 1%
Using the z statistics formula
[tex]\frac{0.006-0.01}{\sqrt{0.000663+0.000825} } \\\\\frac{-0.004}{\sqrt{0.001488} }[/tex]
z = -0.103
p value = z(-0.103) = 0.4589
The pvalue is greater that 0.01
The decision is to fail to reject the null hypothesis.
There is no significant evidence to show that there is a difference in the prevalence of mutation.

nvm just took the test i was right... i am soo smart
The organism are birds including chickens, are structurally similar to the T-Rex.
Are birds like chickens descendants of the T-Rex?Birds share structural similarities with the T-Rex due to their evolutionary relationship. Modern birds including chickens, are believed to be descendants of theropod dinosaurs like the T-Rex. Fossils and genetic evidence support the idea that birds evolved from these ancient reptiles, adapting and evolving over millions of years.
While the T-Rex was a massive predator and birds are much smaller and more diverse, they still share common traits such as hollow bones, beaks, and some aspects of their skeletal structure. This connection provides insight into the fascinating ways that life on Earth has evolved and diversified over time.

Assume that thermometer readings are normally distributed with a mean of 100o F and a standard deviation of 0.15o F. a) Draw and label a sketch of the normal distribution of the thermometer readings. Include all pertinent data for the distribution b) A thermometer is randomly selected and tested. Find the probability that the thermometer reads between 99.86o F and 100.07o F. Draw a sketch of the distribution and shade the probability. Write out any calculator commands that you used.
The parameters of the normal distribution of the thermometer readings are its mean and the standard deviation
The probability that a thermometer reading is between 99.86o F and 100.07o F is 0.5403
The sketch of the normal distribution of the thermometerThe given parameters are:
Mean, μ = 100Standard deviation, σ = 0.15Next, we draw the normal distribution using a graphing calculator.
See attachment for the sketch of the normal distribution of the thermometer
The probability that a thermometer reading is between 99.86o F and 100.07o FThis means that:
x = 99.86 and x = 100.07
The probability is calculated as:
P(99.86 < x < 100.07) = P(x > 99.86) - P(x < 100.07)
Using the attached graph, we have:
P(99.86 < x < 100.07) = 0.5403
