for a special fully discrete 20-year term insurance on (30): the death benefit is 1,000 during the first ten years and 2,000 during the next ten years.
Answers
The cost of the 20-year term insurance will be based on age, health, smoking, and other factors to determine the premium.
The cost of a special fully discrete 20-year term insurance on a 30-year-old would depend on a range of factors, including the insured's age, health, smoking status, and lifestyle. These factors would be used to calculate the risk of death during the 20-year term. The death benefit of 1,000 during the first ten years and 2,000 during the next ten years would also be taken into account when calculating the cost of the policy. Depending on the risk of death and the death benefits, the premium could vary significantly. For example, a 30-year-old in good health with no smoking history could pay less for the policy than a 30-year-old with a pre-existing condition and a smoking history. The premium could also be higher for individuals with riskier lifestyles. Ultimately, the cost of the 20-year term insurance will depend on the risk of death and the death benefit offered by the policy.

a) We have the graph of f(x) and g(x).
The function g(x) seems to be the reflection of f(x) across the x-axis.
This can be represented mathematically as:
\(\begin{gathered} g(x)=-1\cdot f(x) \\ g(x)=-f(x) \end{gathered}\)b) In this case, h(x) is f(x) rotated 180°.
The rule for this transformation is:
\((x,y)\longrightarrow(-x-y)\)Both the value of the function h(x) as the argument, x, change signs, so we should get:
\(h(x)=-f(-x)\)c) In this case, j(x) is the reflection of f(x) across the y-axis.
This can be represented as a change of sign in the argument x.
Then, we can write j(x) as:
\(j(x)=f(-x)\)Answer:
a) g(x) = -f(x)
b) h(x) = -f(-x)
c) j(x) = f(-x)

Answer:
The value is \(t_{\frac{\alpha }{2} , 21 } = 2.518\)
Step-by-step explanation:
From the question we are told that
The sample size is n = 22
Generally the degree of freedom is mathematically represented as
\(df = n- 1\)
=> \(df = 22- 1\)
=> \(df = 21\)
From the question we are told the confidence level is 98% , hence the level of significance is
\(\alpha = (100 - 98 ) \%\)
=> \(\alpha = 0.02\)
Generally from the t distribution table the critical value of \(\frac{\alpha }{2}\) at a degree of freedom of \(df = 21\) is
\(t_{\frac{\alpha }{2} , 21 } = 2.518\)
The surface area of a cell phone screen is 11700 mm2. Use the fact that 10 mm = 1 cm to convert this area to cm2. Round your answer to the nearest whole number.
Answers
The surface area of a cell phone screen is 117 cm².
What is unit conversion?
Unit conversion is the process of converting a quantity expressed in one unit of measurement to an equivalent quantity expressed in another unit of measurement.
We can convert mm² to cm² by dividing the area in mm² by the square of the conversion factor, which is (10 mm / 1 cm) = 100 mm² / cm². Therefore, we have:
11700 mm² / (100 mm² / cm²) = 117 cm²
Rounding to the nearest whole number, we get 117 cm².

Preston measured the button on his shirt. Then he calculated that it has an area of 50.24 square millimeters. What is the button's diameter?
Answers
Answer: Diameter = 8 millimeters
Buttons are circles, so we will use the formula for area of a circle:
A = πr^2
We are solving for the diameter, which is 2 times the radius:
d = 2r
So now we plug in what we know.
The area A = 50.24 square millimeters, therefore we plug it in and simplify:
50.24 square millimeters = πr^2
50.24/π = r^2
15.99 = r^2
squareroot(15.99) = r
r = 4 millimeters
Now we use the radius to calculate the diameter.
r = 4 millimeters
d = 2r
d = 2(4)
diameter = 8 millimeters

Step-by-step explanation:
Answer:
(x+5)² + 4, so c is 5 and d is 4
Step-by-step explanation:
x² + 10x + 29 is a quadratic equation which can be witten as x² + bx + c, where b is 10 and c is 29.
We need to complete the square to get it in the form
(x + c)² + d
Completing the square uses the form:
\((x + \frac{b}{2} ) {}^{2} - ( \frac{b}{2} ) {}^{2} + c\)
substitute b = 10 and c = 29 in this form:
\((x + \frac{10}{2}) {}^{2} - ( \frac{10}{2} ) {}^{2} + 29\)
Simplify further:
\((x + 5) {}^{2} - 25 + 29\)

The statement that is true regarding the function f(x) = (x-4)(x + 1) is that the function is increasing for all real values of x where x < -1 and where x > 4. So, the option is: O The function is increasing for all real values of x where x < -1 and where x > 4.
Explanation: Given function is:f(x) = (x - 4) (x + 1). The graph of the given function is shown below: As it is visible from the graph, the function is decreasing for all real values of x where x lies between -1 and 4 (inclusive).
The turning point of the function is x = -0.5, which is the x-coordinate of the vertex of the parabola. Also, we see that the vertex is the minimum point of the parabola and the y-coordinate of the vertex is -4.25. This means that f(x) ≥ -4.25 for all x. The function is increasing for all real values of x where x < -1 and where x > 4.

Step-by-step explanation:

c = 180 - 60 = 120 degrees
a°+c°+60°=360°
We know this because the sum of all three angles form a circle, which has a measure of 360.°
Now, let’s solve for a°+c°
Subtract 60° from both sides.
a°+c°=360-60
a°+c°=300
We subtracted 60 from 360° because we want to take a “piece” of the angle away to find out the sum of a°+c.° It’s like taking away a sector (section of the area) away from a circle.

The binomials (x - 3) and (x - 10) are factors of the trinomial x² - 13x + 30.
To determine which binomial is a factor of the trinomial x² - 13x + 30, we need to factorize the trinomial completely.
In this case, we need to find two binomials in the form (x - a)(x - b) that satisfy the equation:
(x - a)(x - b) = x² - 13x + 30
So, (x - 3)(x - 10) = x² - 13x + 30.

Lydia buys 5 pounds of apples and 3 pounds of bananas for a total of $8.50. Ari buys 3 pounds of apples and 2
pounds of bananas for a total of $5.25. This system of equations represents the situation, where x is the cost per
pound of apples, and y is the cost per pound of bananas.
5x + 3y = 8.5
3x + 2y = 5.25
If you multiply the first equation by 2, what number should you multiply the second equation by in order to eliminate
the y terms when making a linear combination?
Complete the multiplication and add the equations. What is the result?
What is the price per pound of apples? $
What is the price per pound of bananas?
Answers
Answer:
price per pound of apple = $1.25
price per pound of banana = $0.75
Step-by-step explanation:
Your first question is what value should you multiply the second equation by in order to eliminate the y terms.
The number should be 3. Let us multiply the first equation by 2 and the second equation by 3 and see how y will be eliminated.
10x + 6y = 17...............(i)
9x + 6y = 15.75...........(ii)
10x - 9x = x
6y - 6y = 0
17 - 15.75 = 1.25
x = 1.25
let us find y
10x + 6y = 17...............(i)
10(1.25) + 6y = 17
12.5 + 6y = 17
6y = 17 - 12.5
6y = 4.5
divide both sides by 6
y = 4.5/6
y = 0.75
In order to eliminate y term from the system of equations we multiply equation 2 by -3.
The price per pound of apple is 1.25 dollars and the price per pound of bananas is 0.75 dollars.
Given equations,
\(5x + 3y = 8.5\).........(1)
\(3x + 2y = 5.25\).......(2)
Here x is the cost per pound of apples, and y is the cost per pound of bananas.
According to the question, multiply the first equation by 2, we get
\(10x+6y=17\).....(3)
So, in order to eliminate y term from the system of equations we multiply equation 2 by -3, we get
\(-9x-6y=15.75\).....(4)
Now Adding (3) and (4) equation, we get
\(x=1.25\)
Putting the above value of x in equation 3 we get,
\(10\times1.25+6y=17\\12.5+6y=17\\6y=17-12.5\\6y=4.5\\y=\frac{4.5}{6} \\y=0.75\)
Hence the price per pound of apple is 1.25 dollars and the price per pound of bananas is 0.75 dollars.
