Jacob wants to buy a $500,000 15-year term life policy, and the annual premium rate (per $1000 of face value) for his age group is $6. 78.
Number of 1000 in 500000 is 500000/1000 = 500
the annual premium rate (per $1000 of face value) for his age group is $6. 78.
Total premium is 500 x 6.78 = 3390
The premiun per year is 3390
For 15 years, the total premium is
15 x 3390 = 50850
Therefore, jacob lives until the end of the term of his policy, jacob have paid in premiums overall will be 50850

The correct alternative, based on the parallel, triangle sum, and isosceles triangle criteria, is 2.
How to spot the correct optionAlternative 1
Since the base angle of an isosceles triangle is 52 degrees, let's say the third angle is x, and according to the triangle sum property,
x + 2 * 52 = 180,
x = 76.
triangle at the base
32 + 2x = 180 (triangle sum property for isosceles triangle)
x = 74
In accordance with the triangle sum property for isosceles triangles, the figure demonstrates that the base angle of the triangle at its base is also equal to 76.
False choice: Angles 74 and 76 are not equal.
Alternative 2:
x + 2 * 76 = 180 (triangle sum property for isosceles triangle)
x = 28
The diagram demonstrates that the triangle at the base angle has angle = 28.

installation. A second company charges $55 per month, but offers free
installation. For what number of months is the first plan cheaper than the
second plan?
Write your answer as a number, with no symbols, spaces, or words.
Your answer
Step-by-step explanation:
One cable company charges $50 per month for their basic plan, plus $75 installation. A second company charges $55 per month, but offers free installation. For what number of months is the first plan cheaper than the second plan?
50m + 75 < 55m
subtract 50m from both sides:
50m + 75 -50m < 55m - 50m
75 < 5m
divide both sides by 5:
75/5 < 5m/5
15 < m
or m > 15
so:
The first plan cheaper than the second plan after 16+ months

Answer:
Step-by-step explanation:
Area of the triangle is:
A = 1/2 * (Base * Height)
A = 1/2 * (b * h)
A = 1/2 * (8 * 6.2)
A = 1/2 * 49.6

What is Ascending Order?
When numbers are arranged in ascending order, they are done so from least to largest. We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in ascending order: Determine how many digits each number has.
Given data ,
The numbers in the set S is S = { -27/5 , -4.1 , -5 3/5 , -3 }
Now , the fractions -27/5 and -5 3/5 can be simplified as
-27/5 = -5.4
-5 3/5 = -28/5
= -5.6
And , the numbers in the set S = { -5.4 , -4.1 , -5.6 , -3 }
The larger negative numbers are smaller in value
So , the numbers in their ascending form will be
-5.6 < -5.4 < -4.1 < -3

The sample size for estimating the proportion is 2637.
Given,
How many people should be included in the sample if we want to have 96% confidence that our sample proportion will be within 0.02 of the true fraction of the voting population given the data?
E = 0.02
c = 96% = 0.96
[tex]\hat p[/tex] or P = 0.5 (We have no idea about P, in this case, take P = 0.5)
[tex]\hat p[/tex] = 1 - [tex]\hat p[/tex] = 0.5
Now,
α = 1 - c = 1 - 0.96 = 0.04
α/2 = 0.04/2 = 0.02
⇒ α/2 = 2.054 (using z table)
The sample size for estimating the proportion is given by,

A function is uniquely represented by the set of all pairings (x, f (x)), known as the function graph, which is a popular way of visualizing the function. When the domain and codomain are real number sets, each pair may be thought of as the Cartesian coordinates of a point in the plane. Functions are frequently employed in science, engineering, and the majority of mathematical areas. Most disciplines of mathematics say that functions are "the major subjects of investigation." If the domain and codomain set of two functions f and g are the same and their output values agree over the whole domain, they are equivalent.
