The circumference of the 13cm circle is 40.846 cm.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2πr

Where r is radius and π is constant pi ( π = 3.142 )

Given that; the diameter is 13 cm, the radius is half of that:

radius r = diameter / 2

radius r = 13m / 2

radius r = 6.5 cm

Substituting this into the formula, we get:

C = 2 × π × r

C = 2 × 3.142 × 6.5cm

C = 40.846 cm

Therefore, the circumference is 40.846 cm.

The head of hr in a 50,000 person pharmaceutical company wanted to determine if she should implement a work at home policy for the company.

The HR analyst made an error in assuming that correlation implies causation. Just because there is a correlation between marital status and commuting times.

Additionally, the sample size of 15 employees may not be representative of the entire population of the company, which has 50,000 employees. The small sample size may have introduced sampling bias or sampling error, which could affect the generalizability of the findings.

Hence, the HR analyst should not make a decision about implementing a work at home policy based solely on this small and potentially biased sample.

Answer:

63, 41, and 76

Step-by-step explanation:

A triangle is equal to 180 degrees. So, its angles must be equal to 180 degrees. So, we set 63+2x+8+x+7 equal to 180. Combining like terms, we get 78+3x=180. We want to isolate x, so, we subtract 78 from both sides to get 3x=102. Then we divide by 3 on both sides, x=34. Now, that we have x, we plug it into (2x+8) and (x+7). 2(34)+8= 76 and (34+7)= 41.

The solution is:

b. The function has a maximum value. The maximum value of the function is 18.5.

Here, we have,

Let's consider the equation of a parabola.

f(x) = -2x² + 10x + 6

where,

a: -2

b: 10

c: +6

The sign of "a" determines the openness of the parabola. Since a < 0, the parabola is open downwards and has a maximum.

We can find "x" of the vertex using the following expression.

x(v) = -b/2a = -10/2.(-2) = -2.5

We can find the "y" of the vertex by replacing this x in the equation

y(v) = -2.(2.5)² + 10.(2.5) + 6 = 18.5

The vertex (maximum) is (2.5, 18.5).

Hence, The solution is:

b. The function has a maximum value. The maximum value of the function is 18.5.

The team that has best overall record for the season is the falcons because they have a larger mean value of 20.9 points

The mean is the sum of all values divided by the total number of values. Therefore mean can be expressed as;

mean = sum of item /number of item

The mean value of Eagles = (3+24+14+27+10+13+10+21+24+17+27+7+40+37+55)/15

= 310/15 = 20.67

The mean value of falcons = (24+24+10+7+30+28+21+6+17+16+35+30+28+24+14)/15

Answer:

44°

Step-by-step explanation:

We Know

The sum of three angles in a triangle must add up to 180°.

Let's solve

3x + 15 + 4x - 12 + 79 = 180°

7x + 82 = 180°

7x = 98°

x = 14

Now we put 14 in for the x and find the other 2 missing angles.

3x + 15

3(14) + 15

42 + 15

57°

4x - 12

4(14) - 12

56 - 12

44°

So, the measure of the three angles are: 44°, 57°, and 79°. So, the measure of the smallest angle is 44°

The statements that are true from the list of options are x = 7, y = 10 and QM = 38

7x = 49

So, we have

x = 7

Next, we have

QM = PM

So, we have

6x - 4 = 5y - 12

So, we have

6(7) - 4 = 5y - 12

This gives

5y = 50

So, we have

y = 10

A data analyst who wants to create a visualization that demonstrates how often data values fall into certain ranges should use option A: histogram.

The distribution of a continuous variable is depicted by a histogram, a form of bar graph, by splitting the data into intervals, or bins, and charting the number of observations that fall within each bin. The range of values being measured are shown on the x-axis as intervals or bins, and the frequency or count of observations inside each bin is shown on the y-axis.

When presenting a distribution's shape, such as whether it is symmetrical or skewed, and when locating outliers or data gaps, histograms are especially helpful. They are frequently used to analyze and show data in disciplines including statistics, data science, and quality control.

Part A:

The wavelengths 0.0001 and 10^-3 are equal. This is because 0.0001 = 10^-3.

The surface area of the pyramid is 112 square inches if the perimeter of the base of a square pyramid is 32 inches. Thus, option A is correct.

The perimeter of a square pyramid = 32 inches

The height of a square pyramid = 3 inches

If the perimeter is 32 inches, then the sum of the lengths of all four sides is 32 inches.

Length of side= 4s = 32

Length of side = 8 inches

Area of square = [tex]a^{2}[/tex] = [tex]8^{2}[/tex] = [tex]64 inch^{2}[/tex]

Area of triangle =  (1/2) x base x height

a) The 95% confidence interval for the true proportion of seeds that germinate based on the sample is (0.856, 0.944).

b) The sample does not provide evidence that the claim of 93% germination is wrong, but it does suggest that the true proportion of seeds that germinate may be lower than the claimed proportion.

To find a confidence interval for the true proportion of seeds that germinate, we can use the following formula

CI = p ± z√(p(1-p)/n)

where p is the sample proportion, z is the z-score corresponding to the desired confidence level (95% in this case), and n is the sample size.

a. Using the given values, we have:

p = 180/200 = 0.9

z = 1.96 (from a standard normal distribution table for a 95% confidence level)

n = 200

Plugging these values into the formula, we get

CI = 0.9 ± 1.96√(0.9(1-0.9)/200) = (0.856, 0.944)

Therefore, we can be 95% confident that the true proportion of seeds that germinate is between 0.856 and 0.944.

b. To determine if this provides evidence that the claim is wrong, we can check if the confidence interval includes the claimed proportion of 0.93. Since 0.93 is within the confidence interval of (0.856, 0.944), we cannot conclude that the claim is wrong based on this sample. However, we can say that the sample provides evidence that the true proportion of seeds that germinate may be lower than the claimed proportion.

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π (pi) is a mathematical constant approximately equal to 3.14159.

Using this formula, we can find the circumferences of Circle A and Circle B:

Circumference of Circle A = 2π(21) = 42π meters

Circumference of Circle B = 2π(28) = 56π meters

To answer the second part of the question, yes, the relationship between the radius of a circle and the distance around the circle (circumference) is the same for all circles. The formula for the circumference of a circle, C = 2πr, shows that the circumference is directly proportional to the radius. This means that if we double the radius, we will also double the circumference, and if we triple the radius, we will also triple the circumference, and so on. This relationship holds true for all circles, regardless of their size or location.
