Answer:

  it depends on what the question is (no question is given)

Step-by-step explanation:

What you add or subtract will depend on the problem you're trying to solve, and how you're trying to solve it.

Perimeter

The two left-side vertical segments are 13 and 3. The right-side vertical segment is 16. As you can see, these have the same total: 16.

The top horizontal segment has a length of 21. The two bottom horizontal segments have lengths 16 and 5, for a total of 21—the same as the top segment.

For simple L-shaped figures like this, the overall horizontal lengths and the overall vertical lengths are the same as they would be for a rectangle that is 21 wide and 16 high.

  P = 2(L+W) = 2(21+16) = 2(37) = 74 units

__

Area

The dashed lines divide this figure into 3 rectangles.

  left side: 16 wide by 13 high

  upper right: 5 wide by 13 high

  lower right: 5 wide by 3 high

You can see that the vertical measures must "add up", as must the horizontal measures. This fact helps you determine the lengths of the unmarked sides.

You can compute the area from the three rectangles identified above, or any of several other ways. One of my favorite is to compute the overall area of the 21 wide by 16 high rectangle, then subtract the 16 wide by 3 high white space at lower left.

  area = 21·16 -16·3 = 16·(21 -3) = 16·18 = 288 . . . . square units

Adding the 3 rectangles identified above gives ...

  16·13 +5·13 +5·3 = 208 +65 +15 = 288 . . . . same area

A diagram that models the ratio in the story is shown in the image attached below. If the Capybaras had 80 fans in the stands, the number of Iguanas fans that were in the stands is equal to 96 Iguanas fans.

In Mathematics, a ratio simply refers to a mathematical expression that is typically used for denoting the proportion of two (2) or more quantities with respect to one another and the total quantities. This ultimately implies that, a ratio can be expressed as a quotient.

Let the variable I represent the number of Iguanas fans.

Let the variable C represent the number of Capybaras fans.

Therefore, the ratio of the 6 Iguanas fans to 5 Capybaras fans is given by:

I:C = 6:5

Next, we would determine the number of Iguanas fans if there are 80 Capybaras fans:

6 Iguanas fans = 5 Capybaras fans

x Iguanas fans = 80 Capybaras fans

Cross-multiplying, we have:

x Iguanas fans = (80 × 6)/5

x Iguanas fans = 480/5

x Iguanas fans = 96 Iguanas fans.

What Is Negative Correlation?

A link between two variables known as "negative correlation" occurs when one variable rises as the other falls, and vice versa. In statistics, -1.0 denotes a perfect negative correlation, 0 denotes no connection, and +1.0 denotes a perfect positive correlation. The relationship between two variables is always absolutely opposite when there is a perfect negative correlation.

Therefore, the region which have strongest negative correlation is Midwest.

A. setg 47 23: This option is incorrect because setg is used to set a byte to 1 if the Greater flag (ZF=0 and SF=OF) is set, but the given values of a and b are 47 and 23, respectively, so it does not satisfy the condition for setg to be set.

B. setl 23 47: This option is incorrect because setl is used to set a byte to 1 if the Less flag (SF≠OF) is set, but the given values of a and b are 23 and 47, respectively, so it does not satisfy the condition for setl to be set.

C. sete 23 23: This option is incorrect because sete is used to set a byte to 1 if the Zero flag (ZF=1) is set, but the given values of a and b are 23 and 23, respectively, so it does not satisfy the condition for sete to be set.

D. setne 23 47: This option is correct. setne is used to set a byte to 1 if the Zero flag (ZF=0) is not set, which means the values of a and b are not equal. In this case, the given values of a and b are 23 and 47, respectively, so they are not equal, and setne should be used.

The measurement which is closest to the area of the shaded region of the figure in square centimeters =  24.24 cm²

The correct answer is an option (C)

Here, the diameter of the circle is 8 cm

So, the radius of the circle would be,

r = d/2

r = 8/2

r = 4 cm

Using the formula of area of circle, the area of the described circle would be,

A₁ = π × r²

A₁ = π × 4²

A₁ = 16 × π

A₁ = 50.27 cm²

Also, the square has a measure of 5 cm

Using the formula for the area of square,

A₂ = side²

A₂ = 5²

A₂ = 25 cm²

The area of the shaded region would be,

If cholesterol level were changed to being measured in grams instead of milligrams, the correlation between fat content and cholesterol level would not be affected.

This is because correlation is a measure of the strength and direction of the linear relationship between two variables, and converting the units of measurement does not change the underlying relationship between the variables. So, the correlation coefficient of 0.75 would remain the same whether cholesterol level is measured in milligrams or grams.

The correlation between fat content and cholesterol level for the 20 different brands of American cheese slices is 0.75. If you change the measurement of cholesterol level from milligrams to grams (1 gram = 1000 milligrams), it will not affect the correlation. The correlation coefficient will remain 0.75, as it is unit-less and only represents the strength and direction of the relationship between the two variables.

Answer: 37

Step-by-step explanation:

The given identity is not true for all values of \(`x`\).

To verify the given identity when \(`x = 6π/7`\), substitute the value of \(`x`\) in the given identity.

So,

\(`cos2(x) = cos2(6π/7)`\\ `cos(2x) = cos(2 × 6π/7) \\\\ cos(12π/7)`\\Now, \\`cos(12π/7) = cos(7π − 5π/7) \\ − cos(5π/7)`\)

Using the power reducing formula,

\(`cos2(θ) = 2(1 + cos(2θ)\\ = 1 + cos(2θ)`\\So, \\`cos2(6π/7) = 1 + cos(2 × 6π/7)\\ = 1 + cos(12π/7) \\= 1 − cos(5π/7)`.\)

Hence, the given identity is verified when \(`x = 6π/7`\).

(b) Now, we need to plot the graph of \(`f(x) = cos2(x) − 2/(1 + cos(2x))`\) on the indicated domain. The given identity states that \(`f(x)`\) should be 0 for all values of \(`x`\).

We can substitute a few values of \(`x` $ in `f(x)`\) and check if we get \(`0`\) or not. If we get \(`0`\), then we can conclude that the identity holds true for all values of \(`x`\).  

However, it may be possible that we don't get \(`0`\) for some value of \(`x`\) because the function \(`f(x)`\) is undefined for some values of \(`x`\) (because of the denominator

\(`1 + cos(2x)`).\)

Therefore, we need to check the domain of the given function first. The denominator \(`1 + cos(2x)`\) should not be equal to \(`0`\).

Therefore, \(`cos(2x) ≠ −1`or `2x ≠ π`or `x ≠ π/2`\)  

So, the domain of \(`f(x)` is `R − {π/2}`\).

Now, we can check a few values of \(`x`\) to see if \(`f(x)`\) is \(`0`\) or not. If it is not \(`0`\), then we need to explain why it is not \(`0`\).

Let's check \(`x = 0`.\\`f(0) = cos2(0) − 2/(1 + cos(2 × 0))\\ = 1 − 2/(1 + 1) \\= 1/2 ≠ 0`\)

Let's check \(`x = π/4`.\\`f(π/4) = cos2(π/4) − 2/(1 + cos(2 × π/4))\\ = (1/2)2 − 2/(1 + 0) \\= 1/2 − 2 \\= −3/2 ≠ 0`\)

We can also see that the graph of \(`f(x)`\) is not symmetric about the y-axis. Therefore, the identity does not hold true for all values of \(`x`\).

Hence, the given identity is not true for all values of \(`x`\).

The given function is f(t) = -25,000(1 + ac - kt), where t represents the number of weeks after the outbreak of an epidemic and f(t) represents the number of people in a community who became infected during that time.

The function takes into account the initial population of 25,000 people, the susceptibility coefficient a, the contact coefficient c, and the recovery coefficient k.

In the function, the term (1 + ac - kt) represents the probability of an individual becoming infected at a specific time t. The coefficient a represents the proportion of susceptible individuals in the community, while c represents the rate of contact between susceptible and infected individuals. The coefficient k represents the recovery rate or the rate at which infected individuals stop being contagious.

By evaluating the function f(t) at a specific value of t, we can determine the number of people who became infected during the epidemic t weeks after its outbreak. The function accounts for the initial population, the susceptibility of individuals, the rate of contact, and the recovery rate to calculate the number of infections.

The surface area of a sphere with a radius of 10 feet is approximately 1,256 ft².

The surface area of a sphere refers to the total area that covers the surface of the sphere. It is the sum of all the areas of the small flat faces that make up the sphere.

To find the surface area of a sphere with a radius of 10 feet, we need to use the formula:

Surface Area = 4πr²

Where r is the radius of the sphere.

Plugging in the value of r=10 into the formula, we get:

Surface Area = 4π(10) = 400π

Since π is an irrational number, we cannot calculate its exact value. However, we can approximate it to 3.14. Therefore,

=> Surface Area = 400 * 3.14 = 1256

Rounding to the nearest whole number, we get the surface area of the sphere with a radius of 10 feet as 1,256 ft², which is option (a).
