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

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.

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.

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:

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!

Answer:

$1913.34

Step-by-step explanation:

$1784 (original amount) * 7.25% (sales tax) = $129.34 Tax paid

129.34 + 1784 = Price after tax

The Sharps purchased a new sectional. The cost was $1784.The total amount paid is $1913.34.

We have given that,

The Sharps purchased a new sectional. The cost was $1,784. They also had to pay 7.25% sales tax.

tax paid=original amount × sales tax

$1784 (original amount) * 7.25% (sales tax) = $129.34 Tax paid

129.34 + 1784 = Price after tax

Therefore, The total amount paid is $1913.34.
