Each row cannot have the same number of trees.
What is Divisibility?In mathematics, the term "divisibility" describes a number's ability to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.
As per the given data:
Number of apple trees = 987
Number of rows = 9
To find whether each row has the same number of trees:
If 987 is divisible by 9 then, the same number of trees can be there else not.
= (987/9) = (329/3) = 109.667
Not divisible, so same number of trees cannot be there.
Hence, each row cannot have the same number of trees.

A rectangle is drawn at (-4,-2) (-1,-2) (-4,-4) and (-1,-4). What is the perimeter?
Answer:
12
Step-by-step explanation:
In a model based on a weakly dependent time series with serial correlation and strictly exogenous explanatory variables, _____. a. the feasible generalized least square estimates are BLUE b. the feasible generalized least square estimates are asymptotically more efficient than OLS estimates c. the feasible generalized least square estimates are unbiased d. the feasible generalized least square estimates are asymptotically less efficient than OLS estimat
Answer:
Option a (the feasible........BLUE) is the correct option.
Step-by-step explanation:
The association with a certain variable and perhaps a lagging representation with its own over time is termed as Serial correlation. OLS could even deliver skewed outcomes and can't thus be utilized attributable to serial correlation. GLS has always been then used that follows BLUE, in other words, GLS even though in this circumstance becomes an appropriate Unbiased Linear Estimator.The other alternatives are not related to the given scenario. So the above is the right option.
In a clinical trial, 780 participants suffering from high blood pressure were randomly assigned to one of three groups. Over a one-month period, the first group received the experimental drug, the second group received a placebo, and the third group received no treatment. The diastolic blood pressure of each participant was measured at the beginning and at the end of the period and the change in blood pressure was recorded. The average change in blood pressure was calculated for each of the three groups and the three averages were compared.
A. This was an experiment rather an observational study. How do we know that?
B. Identify the factors and levels.
C. Are all the principles of experimental design included in this experiment? Explain.
Answer:
A. We know that this was an experiment rather than an observational study because treatments were administered, with the first group receiving the experimental drug, the second group receiving a placebo, and the third group receiving no treatment."
B. The factors are the variables. The independent variable was group three that received no treatment, while the dependent variables were the first and second groups that received some treatments. Another variable is the change in blood pressure recorded at the end of the period.
The levels refer to the different treatments that were administered to the three groups: experimental drug, placebo, and no treatment.
C. The principles of experimental design are Randomization, Repetition, and Control. We are not aware of how the participants were chosen and this experiment was not replicated in the scenario. We can affirm that there is Control because the three groups were not given the same treatment.
Step-by-step explanation:
In an observation, the researcher does not attempt to change any variables. She simply observes and then records her observations. In an experimental study, the researcher creates a control group and, also at least, one testable group. The purpose is to compare the control group and the testable group.

A study of peach trees found that the average number of peaches per tree was 725. The standard deviation of the population is 70 peaches per tree. A scientist wishes to find the 95% confidence interval for the mean number of peaches per tree. How many trees does she need to sample to obtain an average accurate to within 10 peaches per tree
Answer:
She needs to sample 189 trees.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
The standard deviation of the population is 70 peaches per tree.
This means that [tex]\sigma = 70[/tex]
How many trees does she need to sample to obtain an average accurate to within 10 peaches per tree?
She needs to sample n trees.
n is found when M = 10. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]10 = 1.96\frac{70}{\sqrt{n}}[/tex]
[tex]10\sqrt{n} = 1.96*70[/tex]
Dividing both sides by 10:
[tex]\sqrt{n} = 1.96*7[/tex]
[tex](\sqrt{n})^2 = (1.96*7)^2[/tex]
[tex]n = 188.2[/tex]
Rounding up:
She needs to sample 189 trees.
What is the distance between the points (-6, 2) and (-4, 7)? Round to the nearest tenth if necessary.
Answer:
The distance is 5.4.
Step-by-step explanation:
Hope this helps!! Have an Amazing day!!
Answer:
5.385
Step-by-step explanation:
Use the distance formula with (-6,2) (-4,7)
[tex]\sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2 }[/tex]
[tex]\sqrt{(-4--6)^2 + (7-2)^2 }[/tex]
[tex]\sqrt{(2^2) + (5^2)}[/tex]
[tex]\sqrt{4+25}[/tex]
[tex]\sqrt{29}[/tex]
= 5.385
A fair coin is tossed 5 times. Compute the probability of tossing 5 heads in a row.
Answer:
50%
Step-by-step explanation:
There is 2 side out of 100% half is 50 :D gl and mb if its wrong!
Answer:
* Here we assume that the coin tossed is fair.
Probability of event A = # Favorable cases for event A/ # Exhaustive cases for event B
Where
Favorable cases means outcomes of an experiment that favors a particular event
Exhaustive cases means, number of total possible outcomes.
For tossing a coin one time:
# Favorable cases = 1 (getting head)
# Exhaustive cases = 2 (two outcomes, say, head and tail)
So, P(getting head in a single toss) = 1/2
For tossing a coin two times:
# Favorable cases = 1 (getting 2 heads, say, HH)
# Exhaustive cases = 2*2 or 2^2 (4 outcomes, say, HH, HT, TH, TT)
So, P(getting 2 heads in two tosses of a coin) = 1/4
Similarly, for tossing a coin five times:
# Favorable cases = 1 (getting 3 heads, say, HHHHH)
# Exhaustive cases = 2*2*2*2*2 or 2^5 (32 outcomes, say, HHHHH, THHHH, ..... etc)
So, P(getting head in 5 tosses of a coin) = 1/32
Step-by-step explanation:

State the null hypothesis H0 and the alternative hypothesis Ha in each case. Be sure to identify the parameters that you use to state the hypotheses.
(a) A university gives credit in first-year calculus to students who pass a placement test. The mathematics department wants to know if students who get credit in this way differ in their success with second-year calculus. Scores in second-year calculus are scaled so the average each year is equivalent to a 75. This year 17students who took second-year calculus passed the placement test.
H0:μ>75;Ha:μ=75
H0:μ<75;Ha:μ=75
H0:μ=17;Ha:μ>17
H0:μ=17;Ha:μ≠17
(b) Experiments on learning in animals sometimes measure how long it takes a mouse to find its way through a maze. The mean time is 24 seconds for one particular maze. A researcher thinks that playing rap music will cause the mice to complete the maze slower. She measures how long each of 17 mice takes with the rap music as a stimulus.
H0:μ=24sec;Ha:μ>24sec
H0:μ=24sec;Ha:μ≠24sec
H0:μ>17sec;Ha:μ=17sec
H0:μ=17sec;Ha:μ<17sec
H0:μ=24sec;Ha:μ<24sec
(c) The average square footage of one-bedroom apartments in a new student-housing development is advertised to be 850 square feet. A student group thinks that the apartments are smaller than advertised. They hire an engineer to measure a sample of apartments to test their suspicion.
H0:μ=850ft2;Ha:μμ850ft2
H0:μ>850ft2;Ha:μ=850ft2
H0:μ=850ft2;Ha:μ>850ft2
H0:μ=850ft2;Ha:μ<850ft2
H0:μ<850ft2;Ha:μ=850ft2

(C)
[tex]H_0:\mu=850\ ft^2\\H_a:\mu<850 \ ft^2[/tex]
Step-by-step explanation:
Null hypothesis [tex](H_0)[/tex]: It is a statement showing population parameters as per the objective of the study. It generally takes "≤,≥,=" signs. Alternative hypothesis [tex](H_a)[/tex]: It is also a statement describing population parameters as per the objective of the study. It generally takes ">, <, ≠" signs.(A) Objective: Scores in second-year calculus are scaled so the average each year is equivalent to a 75 or not.
[tex]H_0:\mu=75\\H_a:\mu\neq75[/tex]
(B) Objective: The mean time is 24 seconds or more for one particular maze.
[tex]H_0:\mu=24\ sec\\H_a:\mu>24\ sec[/tex]
(C) Objective: The average square footage of one-bedroom apartments in a new student-housing development is advertised to be 850 square feet or smaller.

ein rechteckiger Bauplatz ist 39,5 m lang und 32,5 m breit . wie teuer ist der Grund ,wenn ein Quadratmeter Bauland 185,50 euro kostet???
So first you need to find the area of the building site which is:
length x width
39.5m x 32.5m
= 1283.75[tex]m^{2}[/tex]
We know that one square meter costs 185.50 euros.
1[tex]m^{2}[/tex] = 185.50 euros
1283.75[tex]m^{2}[/tex] = 238135.625 euros
I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are 238134.86 and 238135.86.
sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!
