  d.  q^2/(4π)

Step-by-step explanation:

The circumference in terms of r is ...

  q = 2πr

So, the radius in terms of q is ...

  r = q/(2π)

The area in terms of radius is ...

  p = πr^2

so, in terms of q, it is ...

  p = π(q/(2π))^2 = (π/π^2)(q^2/4)

  p = q^2/(4π)

which is quite different from the correct answer of q^2/(4π).

Answer:

a) Permutation, because the coach has to designate an order in which they will take penalty

b) There are 55,440 different ways for the coach to do this.

Step-by-step explanation:

It the order is not important, we have a combination.

If the order is important, we have a permutation.

In this question:

5 players from a set of 11 and designate an order.

This means that the order is important, and we have a permutation.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

(a) Is this a permutation or a combination? Why?

Permutation, because the coach has to designate an order in which they will take penalty

(b) How many different ways are there for the coach to do this?

[tex]P_{(11,5)} = \frac{11!}{(11-5)!} = 55440[/tex]

There are 55,440 different ways for the coach to do this.

Step-by-step explanation:

Answer: A.

The system is consistent because the rightmost column of the augmented matrix is not a pivot column.

Explanation: a system is consistent if and only if the rightmost column of the augmented matrix is not a pivot column. Since every column of the coefficient matrix is a pivot column, none of the leading coefficients are in the rightmost column of the augmented matrix. Therefore the rightmost column of the augmented matrix cannot be a pivot column and the system must be consistent.

Answer:

Option (1). 34°

Step-by-step explanation:

From the figure attached, CE and CD are the radii of the circle C.

Central angle CED formed by the intercepted arc DE = 68°

Since measure of an arc = central angle formed by the intercepted arc

Therefore, m∠CED = 68°

Since m∠EFD = [tex]\frac{1}{2}(m\angle ECD)[/tex] [Central angle of an intercepted arc measure  the double of the inscribed angle by the same arc]

Therefore, m∠EFD = [tex]\frac{1}{2}(68)[/tex]

                               = 34°

Therefore, Option (1) 34° will be the answer.

Answer:

the dimensions in the drawing are 16.25 inches by 6.375 inches

Step-by-step explanation:

The first thing is to use the same unit on the scale, that is, they tell us that the scale is 1:40 but that scale cannot be applied because they are different units of measurement.

The answer is preferable to give it in inches because it is more adapted to the measurements in a drawing, therefore we will pass the scale all in inches, knowing that 1 foot is 12 inches:

40 feet * 12 inches / 1 foot = 480 inches, therefore the scale is 1: 480

Now, if we pass the dimensions that give us inches, we are left with:

650 feet * 12 inches / 1 foot = 7800 inches

255 feet * 12 inches / 1 foot = 3060 inches

Now applying the scale:

7800/480 = 16.25

3060/480 = 6.375

It means that the dimensions in the drawing are 16.25 inches by 6.375 inches

Answer:

Hospital A is less likely to record an average birth weight of at least 3400 g.

Step-by-step explanation:

Applying the Central Limit Theorem and the normal probability distribution.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Applying the Central Limit Theorem to find the z-score.

[tex]Z = \frac{X - \mu}{\sigma} = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

Probability of an average birth weight of at least 3400 g?

This probability is 1 subtracted by the pvalue of Z when X = 3400.

Mean is 3100, so [tex]\mu = 3100[/tex]

Suppose s is the same for both.

Hospital A:

n = 50. So

[tex]Z = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

[tex]Z = \frac{3400 - 3100}{\frac{s}{\sqrt{50}}[/tex]

[tex]Z = \frac{300\sqrt{50}}{s}[/tex]

Hospital B:

n = 10. So

[tex]Z = \frac{X - \mu}{\frac{s}{\sqrt{n}}[/tex]

[tex]Z = \frac{3400 - 3100}{\frac{s}{\sqrt{10}}[/tex]

[tex]Z = \frac{300\sqrt{10}}{s}[/tex]

Comparasion:

[tex]\frac{300\sqrt{50}}{s} > \frac{300\sqrt{10}}{s}[/tex]

This means that hospital A has the higher z-score.

The higher the z-score, the higher the pvalue.

So, for A, 1 subtracted by the pvalue of Z when give a lower value than the 1 subtracted by the pvalue of Z in b. This means that hospital A is less likely to record an average birth weight of at least 3400 g.

Answer:

[tex] x+y = 30[/tex]   (1)

[tex] 1.95x+ 2.85y = 78.30[/tex]   (2)

From equation (1) we can solve for x and we got:

[tex] x = 30-y[/tex] (3)

Replacing (3) into (2) we got:

[tex] 1.95(30-y) +2.85 y = 78.30[/tex]

And solving for y we got:

[tex] 58.5 -1.95 y +2.85 y = 78.30[/tex]

[tex] 0.9 y = 19.8[/tex]

[tex] y = 22[/tex]

And then solving for x we got:

[tex] x = 30-22 = 8[/tex]

So then we have 8 donuts and 22 cupcakes

Step-by-step explanation:

Let x the number of donuts and y the number of cupcakes, from the info given we can set up the following equations:

[tex] x+y = 30[/tex]   (1)

[tex] 1.95x+ 2.85y = 78.30[/tex]   (2)

From equation (1) we can solve for x and we got:

[tex] x = 30-y[/tex] (3)

Replacing (3) into (2) we got:

[tex] 1.95(30-y) +2.85 y = 78.30[/tex]

And solving for y we got:

[tex] 58.5 -1.95 y +2.85 y = 78.30[/tex]

[tex] 0.9 y = 19.8[/tex]

[tex] y = 22[/tex]

And then solving for x we got:

[tex] x = 30-22 = 8[/tex]

So then we have 8 donuts and 22 cupcakes

Answer:

Step-by-step explanation:

Hello!

The random sample of n= 16 participants was asked to taste test two different sodas cans and rate them on a scale from 1 to 10. The cans contained the same type of soda but differ in color.

Since each participant tasted and ranked the two types of soda cans, you have per person a pair of data (X₁;X₂):

Where

X₁: Rank given to the red soda.

X₂: Rank given to the blue soda.

As said, the data is arranged in pairs per experimental unit, so these two variables are dependent, to study them is best to determine a third variable, the difference between X₁ and X₂:

Xd: X₁ - X₂

Assuming Xd~N(μd;σd²)

The objective is to test if there is any difference between the ratings based on the can color. The statistic hypotheses are:

H₀: μd=0

H₁: μd≠0

To calculate the descriptive statistics you have to calculate first the difference of each pair of ratings (see table in attachment)

Mean:

X[bar]d= ∑Xd/n= -6/16= -0.38

Variance

[tex]S_d^2=\frac{1}{n-1} [sumX_d^2-\frac{(sumXd)^2}{n} ]= \frac{1}{15}[64-\frac{(-6)}{^16} ]= 4.12[/tex]

Standard deviation

Sd= √4.12= 2.03

Statistic [tex]t= \frac{X[bar]_d-Mu_d}{\frac{Sd}{\sqrt{n} } } ~~t_{n-1}[/tex]

Df: n-1= 16-10 15

[tex]t_{H_0}= \frac{-0.38-0}{\frac{2.03}{4} } = -0.74[/tex]

P-value:

P(t₁₅≤-0.74) + P(t₁₅≥0.74)= P(t₁₅≤-0.74) + (1 - P(t₁₅≤0.74))= 0.2354 + (1 - 0.7646)= 0.4708

The decision rule for the p-value approach is:

If p-value ≤ α, reject the null hypothesis.

If p-value > α, do not reject the null hypothesis.

α: 0.05

The p-value is greater than the level of significance, the decision is to not reject the null hypothesis.

At a 5% significance level, there is no significant evidence to reject the null hypothesis. You can conclude that there is no difference between the rankings of the red and blue cans. I.e. there is no evidence to suggest that the can color changes the average ranting of the soda.

I hope this helps!

Answer:

S) 230°

T) 45°

Step-by-step explanation:

S) m∠RST = 30°.  An inscribed angle is half the central angle, so RT = 60°.

SR = 70°, so ST = SR + RT = 60° + 70° = 130°.

SPT = 360° − ST = 360° − 130° = 230°

T) m∠DCA = 60°.  An inscribed angle is half the central angle, so AD = 120°.

DB = AD − BA = 120° − 75° = 45°
