Answer:

III

Step-by-step explanation:

The option that would most likely contribute toward lowering the premium a policyholder pays for life insurance is III - maintaining good health.

Choosing whole instead of term insurance, decreasing the death benefit, and taking up smoking would increase the premium a policyholder pays for life insurance. Whole life insurance typically has higher premiums than term life insurance, decreasing the death benefit reduces the amount of coverage provided by the policy, and taking up smoking increases the risk of premature death and therefore increases the likelihood that the policy will need to pay out.

On the other hand, maintaining good health reduces the risk of premature death and lowers the likelihood that the policy will need to pay out. Therefore, insurance companies typically offer lower premiums to policyholders who maintain good health.

The average percentage of time spent studying is 8.64%.

To find the average percentage of time spent studying, we need to first add up the total hours and total percentage of all the students. Then, we can divide the total percentage by the total hours to find the average percentage of time spent studying.

Total hours = 18 + 10 + 2 + 6 + 8 = 44 hours
Total percentage = 100% + 80% + 50% + 70% + 80% = 380%

Average percentage = Total percentage / Total hours = 380% / 44 hours = 8.64%

Answer: cos B-sin²A = cos²A-sin-B

Step-by-step explanation:

Answer: cos B-sin²A = cos²A-sin-B

Explanation:

Using the double angle identity, we can express the left side of the equation as:

cos(A + B).cos(A-B) = cos A.cos B - sin A.sin B

Now, using the Pythagorean identity, we can rewrite the right side of the equation as:

cos²A-sin-B = cos A.cos B - sin A.sin B

Hence, we can conclude that cos(A + B).cos(A-B) = cos B-sin²A = cos²A-sin-B

Answer: Read the step by step explanation for the answer.

Step-by-step explanation:

We can prove this trigonometric identity using the product-to-sum and Pythagorean identities as follows:

Starting with the left-hand side (LHS):

cos(A + B).cos(A - B)

Using the product-to-sum identity:

= [cos A cos B - sin A sin B][cos A cos B + sin A sin B]

= cos²A cos²B - sin²A sin²B

Using the Pythagorean identity:

= cos²A(1 - sin²B) - sin²A(1 - cos²B)

= cos²A - cos²A sin²B - sin²A + sin²A cos²B

= cos²A - sin²A + sin²A cos²B - cos²A sin²B

Using the Pythagorean identity:

= cos²A - sin²A + sin²A(1 - sin²B) - cos²A sin²B

= cos²A - sin²A + sin²A - sin²A sin²B - cos²A sin²B

= cos²A - sin²A + sin²A cos²B - sin²B cos²A

= cos²A - sin²A + cos²A sin²B - sin²B cos²A

Using the Pythagorean identity:

= cos²A - sin²A + cos²A - sin²B

= 2cos²A - sin²A - sin²B

= cos²A + cos²A - sin²A - sin²B

= cos²A + sin²A cos²B - sin²B

= RHS

Therefore, we have shown that (b) cos(A + B).cos(A-B) = cos B-sin²A = cos²A-sin-B.

Step-by-step explanation: use a calculator/online calculator

The value of the sample variance and the sample standard deviation for the given data is equal to 47.4 and 6.9 respectively.

Data values are,

23, 12, 5, 9,8

Number of observations 'n' = 5

Mean = ( sum of all the observations ) / ( number of observations)

         = (23 + 12 + 5 + 9 + 8) / 5

         = 57 /5

         = 11.4

Deviations of each data point from the mean,

(23 - 11.4) = 11.6

(12 - 11.4) = 0.6

(5 - 11.4) = -6.4

(9 - 11.4) = -2.4

(8 - 11.4) = -3.4

Square each deviation is equal to,

11.6² = 134.56

0.6² = 0.36

(-6.4)² = 40.96

(-2.4)² = 5.76

(-3.4)² = 11.56

Sample Variance = ( Sum of squared deviation )/ ( n - 1)

⇒Sample Variance = (134.56 + 0.36 + 40.96 + 5.76 + 11.56) / (5-1)

⇒Sample Variance = 47.35

⇒Sample Variance = 47.4(rounded to one decimal place)

Now,

Standard deviation = √variance

Substitute the value we get,

⇒ Standard Deviation = √(47.35)

⇒ Standard Deviation = 6.9 (rounded to one decimal place)

Therefore, the sample variance is 47.4 and the sample standard deviation is 6.9.

y = 2.50 / (1 + 15.80^−x)

You can use technology to approximate the given data with a logistic regression curve y = N/(1 + Ab^−x).

To do this, you'll need to calculate the parameters A, N, and b. To calculate A and N, you can use the values of y at the extremes of x. At x = 0, y = 3.0 and at x = 150, y = 9.9. So, A = (9.9 - 3.0) / (1 - 0.003^150) and N = 9.9 - A*0.003^150. Then, b can be calculated using the average of the logarithm of all x values. The final logistic regression curve will be:

Answer: A cup of coffee costs $2.50 and a bagel costs $3.50.

Step-by-step explanation: Let's use the following variables to represent the price of each item:

c: price of a cup of coffee (in dollars)

b: price of a bagel (in dollars)

From the problem statement, we know that:

b = c + 1 (a bagel costs $1 more than a cup of coffee)

We also know that you bought 4 cups of coffee and 6 bagels for a total of $31. This can be expressed as:

4c + 6b = 31

Now we can substitute the first equation into the second equation to eliminate b:

4c + 6(c + 1) = 31

Simplifying this equation, we get:

10c + 6 = 31

Subtracting 6 from both sides, we get:

10c = 25

Dividing both sides by 10, we get:

c = 2.5

Now we can use the first equation to find the value of b:

b = c + 1 = 2.5 + 1 = 3.5

Therefore, a cup of coffee costs $2.50 and a bagel costs $3.50.

The height of the cylinder is approximately 2.45 inches.

Volume is the measure of the space occupied by a three-dimensional object. It is typically expressed in cubic units.

The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

Substituting the given values, we get:

1 and 1/16 = π(1/4)²h

Simplifying and solving for h, we get:

h = (1 and 1/16) / (π(1/4)²)

h = (17/16) / (π/16)

h = 17/π

Approximating using π = 22/7, we get:

h ≈ 17 / (22/7)

h ≈ 2.45 inches (rounded to two decimal places)

Therefore, the height of the cylinder is approximately 2.45 inches

Step-by-step explanation:

To find the volume of a rectangular prism your going to do length times width times height.

Your length is 7 1/4m

Your height is 14m

Your width is 9 1/2m

So we are going to do 7 1/4 * 9 1/2 * 14

Which will give you 964.25

The factored form of the polynomial is p(z) = (2z - 5)(z^(2) + 2z + 37).

To write the polynomial p(z) in factored form as a product of linear and quadratic expressions using integer coefficients only, we need to find the other zeros of the polynomial.

Since one of the zeros is a complex number, z = -1 + 6i, the other complex zero will be its conjugate, z = -1 - 6i. This is because complex zeros of polynomials with real coefficients always come in conjugate pairs.

Now, we can write the quadratic expression that has these two complex zeros as

(z - (-1 + 6i))(z - (-1 - 6i)) = (z + 1 - 6i)(z + 1 + 6i) = (z + 1)^(2) - (6i)^(2) = z^(2) + 2z + 1 - 36i^(2) = z^(2) + 2z + 37.

Since the polynomial p(z) is of degree 3, there must be one more zero, which we can find by dividing p(z) by the quadratic expression we just found:

p(z)/(z^(2) + 2z + 37) = 2z^(3)/(z^(2) + 2z + 37) - z^(2)/(z^(2) + 2z + 37) + 64z/(z^(2) + 2z + 37) - 185/(z^(2) + 2z + 37) = 2z - 5

So the other zero is z = 5/2.

Now,
p(z) = 2(z - 5/2)(z^(2) + 2z + 37) = (2z - 5)(z^(2) + 2z + 37)

So the factored form of the polynomial is p(z) = (2z - 5)(z^(2) + 2z + 37).

Following are the measures of the angles given :∠ ABC = 180, ∠ BCD = 180, ∠ CDA = 270, ∠ DAB = 270.

What is parallel lines ?

Parallel lines are two or more lines that are always the same distance apart and never intersect, no matter how far they are extended.

Since AB is parallel to DC and AD is parallel to BC, we know that angles A and C are corresponding angles and angles B and D are also corresponding angles. Corresponding angles are congruent when two parallel lines are intersected by a transversal.

So, we have:

∠ A = ∠ C

∠ B = ∠ D

Given:

∠ D = 3x - 75

∠ B = x + 35

We can solve for x using the fact that the sum of the angles in a quadrilateral is 360 degrees:

∠ A + ∠ B + ∠ C + ∠ D = 360

Substituting the values we know, we get:

∠ A + (x + 35) + ∠ C + (3x - 75) = 360

Simplifying, we get:

4x - 40 = 360

4x = 400

x = 100

Now we can substitute x = 100 into the expressions for ∠ B and ∠ D to find their values:

∠ B = x + 35 = 100 + 35 = 135

∠ D = 3x - 75 = 3(100) - 75 = 225

Since angles A and C are corresponding angles, we know that:

∠ A = ∠ C = 180 - ∠ B = 180 - 135 = 45

Therefore, we have:

∠ ABC = ∠ A + ∠ B = 45 + 135 = 180

∠ BCD = ∠ B + ∠ C = 135 + 45 = 180

∠ CDA = ∠ C + ∠ D = 45 + 225 = 270

∠ DAB = ∠ D + ∠ A = 225 + 45 = 270\

So, we can see that angles ABC and BCD are straight angles (180 degrees) and angles CDA and DAB are reflex angles (more than 180 degrees).

Therefore, Following are the measures of the angles given :∠ ABC = 180, ∠ BCD = 180, ∠ CDA = 270, ∠ DAB = 270.

The final answer in simplest form is 7[tex]x^{2}[/tex] - 2x + 10/x.

To find the quotient of (28[tex]x^{5}[/tex]-8[tex]x^{4}[/tex]+40[tex]x^{(2)[/tex])/(4[tex]x^{3}[/tex]), we need to divide each term in the numerator by the denominator.

(28[tex]x^{5}[/tex])/(4[tex]x^{3}[/tex]) = (28/4)[tex]x^{(5-3)[/tex] = 7[tex]x^{2}[/tex]

Next, we divide -8[tex]x^{4}[/tex] by 4[tex]x^{3}[/tex]:

(-8[tex]x^{4}[/tex])/(4[tex]x^{3}[/tex]) = (-8/4)[tex]x^{(4-3)[/tex] = -2x

Finally, we divide 40[tex]x^{2}[/tex] by 4[tex]x^{3}[/tex]:

(40[tex]x^{2}[/tex])/(4[tex]x^{3}[/tex]) = (40/4)[tex]x^{(2-3)[/tex] = 10[tex]x^{(-1)[/tex] = 10/x

Putting it all together, we get:

(28[tex]x^{5}[/tex] - 8[tex]x^{4}[/tex] + 40[tex]x^{2}[/tex])/(4[tex]x^{3}[/tex]) = 7[tex]x^{2}[/tex] - 2x + 10/x

Step-by-step explanation:

This is a set of simultaneous equations. To solve them, you need to substitute one into the other. The easiest way to do this would be to rearrange x - y = -6 to make x the subject:

x = -6 + y

x = y - 6

Now we can substitute this equation into y = -x^2 + 5x + 6:

y = -(y - 6)^2 + 5(y - 6) + 6

Now simplify this equation, and rearrange to make it equal to 0:

y = -y^2 + 12y - 36 + 6

y = -y^2 + 12y - 30

0 = -y^2 + 12y - y - 30

-y^2 + 11y - 30 = 0

Now solve this quadratic equation to obtain two solutions:

y = 5, y = 6

Now substitute these values back into one of the starting equations to find the respective values for x:

When y = 5:

x - 5 = -6

x = -1

When y = 6

x - 6 = -6

x = 0

Therefore, the x solutions are -1 and 0.

The sum of the two polynomials is 12x^(5) - 5x^(3) - 5x^(2).

To find the sum of the two polynomials, we need to add the coefficients of the like terms. Like terms are terms that have the same variable and exponent.

Step 1: Identify the like terms in the two polynomials.
- The like terms are 8x^(5) and 4x^(5), -5x^(3) and 0 (since there is no x^(3) term in the second polynomial), x^(2) and -6x^(2).

Step 2: Add the coefficients of the like terms.
- 8x^(5) + 4x^(5) = 12x^(5)
- -5x^(3) + 0 = -5x^(3)
- x^(2) + -6x^(2) = -5x^(2)

Step 3: Combine the terms to get the sum of the two polynomials.
- 12x^(5) + -5x^(3) + -5x^(2)

Step 4: Simplify the expression if possible.
