Suppose a life insurance company sells a $150,000 one-year term life insurance policy to a 23-year-old female for $260 the expected value of this policy to the insurance company will be:$198.35
Expected value=(260×0.999589)-(150,000-$260)×(1-0.999589)
Expected value=259.89314-149,740×0.000411
Expected value=$198.35
Interpretation of the Expected value:
Based on the above calculation the insurance company is expect to make an average profit of $198.35 on every 23-year-old female it insured for 1 year.
Inconclusion Suppose a life insurance company sells a $150,000 one-year term life insurance policy to a 23-year-old female for $260 the expected value of this policy to the insurance company will be:$198.35
Suppose A={0,12,−3,7,18}, B={−1,5,7,18}, and C={−3,5,9}. What is A∩(B∪C)?
Answer: {-3, 7, 18}
Step-by-step explanation:
B ∪ C = {-3, -1, 5, 7, 9, 18}
A ∩ (B∪C) = {-3, 7, 18}
please give me a brainliest answer
Answer:
A∩(B∪C)={-3, 7, 18}Step-by-step explanation:
First we look at PEMDAS.
In A∩(B∪C), parentheses come first.
So, we do B∪C.
The ∪ symbolizes union, which means you have to combine the elements of the two sets.
If B={−1,5,7,18}, and C={−3,5,9}, then both of them together is {-3,−1,5,7,9,18}. I used underlining and italics to show where the numbers came from. There is a 5 in both sets, but you only have to put it once.
B∪C={-3,−1,5,7,9,18}.
Now that we have B∪C, we can solve for A∩(B∪C).
∩ means intersection, so you find the elements in both sets. Basically, just look for numbers that appear in both A and B∪C.
B∪C={-3,−1,5,7,9,18}
A={0,12,-3,7,18}
Therefore, A∩(B∪C)={-3, 7, 18}

How many triangles are here
Answer:
6 types of triangles?
isosceles, equilateral, scalene, obtuse, acute, and right
How many Triangles are where ?
there is no image of triangles
thus i can not tell you how many triangles there are
Which values of a, b, and c correctly complete the division?
A. a = 4, b = 5, c = 6
B. a = 1, b = 6, c = 5
C. a = 1, b = 5, c = 6
D. a = 4, b = 6, c = 5
If we compare both sides of the equation we get,
D. a = 4, b = 6 and c = 5

identify each classification of the real number system that can describe the set of numbers shown {3, 9, 147, 400}
) Integer
) Irrational
) Real
) Rational
) Whole
) Natural
Step-by-step explanation:
all of these 4 numbers are
integer (whole numbers positive and negative).
real (every whole number can be written as e.g. 3.0 and is part of the real numbers).
rational (as any whole number can be written as e.g. 3/1 and is part of the rational numbers).
whole (no fractions).
natural (they are in the set of [1, 2, 3, ... infinity) ).
the only thing here they are not is irrational, as to be irrational they would need to have an infinite sequence of digits after the decimal point without any repeating pattern.

Simplify the expression
Answer:
[tex]-\frac{4}{7} -\frac{8}{7} i\sqrt{5}[/tex]
Step-by-step explanation:
To rationalize the denominator, we would have to multiply by the complex conjugate of 6 + 2i√5 which is 6 - 2i√5:
[tex]\frac{8-8i\sqrt{5} }{6+2i\sqrt{5} } *\frac{6-2i\sqrt{5} }{6-2i\sqrt{5} }[/tex]
The denominator resembles the difference of squares:
6^2 - (2i√5)^2
36 + 20
56
Next we would need to multiply the numerator, but before, notice we can factor out 8 from 8 - 8i√5:
[tex]\frac{8(1-i\sqrt{5})(6-2i\sqrt{5}) }{56}[/tex]
We can cancel that 8 with that 56 in the denominator:
[tex]\frac{6-2i\sqrt{5}-6i\sqrt{5}-10}{7}[/tex]
This simplifies to:
[tex]\frac{-4-8i\sqrt{5} }{7}[/tex]
which is the same as:
[tex]-\frac{4}{7} -\frac{8}{7} i\sqrt{5}[/tex]

a textbook store sold a combined total of 348 history and chemistry text in week.The number of history textbooks sold was three times the number of chemistry books were sold. how many book of each type were sold.
Answer:
x=87, y=261
Step-by-step explanation:
x+y=348 and 3x=y
plug 3x in for y.
x+(3x)=348
4x=348
x=87
plug x in to solve for y.
3(87)=y
y=261

Coverte 2.75 into fraction
Answer:
2 3/4 or 11/4
Step-by-step explanation:
2.75 = 11/4 = 2 3/4 as a fraction
To convert the decimal 2.75 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
2.75 = 2.75 / 1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,
2.75 / 1 = (2.75 x 100)/(1 x 100) = 275/100.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(275,100) = 25. So,
(275 ÷ 25)/ (100 ÷ 25) = 11/4 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 275 /100
is also equal to 2 3/4 when expressed as a mixed number.
How to Convert a Decimal to a Fraction - Steps
Step 1: Write down the decimal as a fraction of one (decimal/1);
Step 2: If the decimal is not a whole number, multiply both top and bottom by 10 until you get an interger at the numerator.
Step 3: Simplify (or reduce) the fraction if it is not in the simplest form.

The line y+4=3/4(x-8) contains point (a,2). Find a.
Answer:
a = 16
Step-by-step explanation:
[tex]y + 4 = \dfrac{3}{4}(x-8)\\\\y + 4 = \dfrac{3}{4}x- \dfrac{3}{4}*8\\\\y +4 = \dfrac{3}{4}x-3*2\\\\y+4+6= \dfrac{3}{4}x \\\\y+10= \dfrac{3}{4}x[/tex]
Now plugin x = a and y =2 in the above equation,
[tex]2+10= \dfrac{3}{4}*a\\\\12= \dfrac{3}{4}a\\\\12* \dfrac{4}{3}=a\\\\a=4*4\\\\a=16[/tex]

please help me please help me
Answer:
Associative property of multiplication
Step-by-step explanation:
The word "associative" comes from "associate" or "group"; the Associative Property is the rule that refers to grouping. For addition, the rule is "a + (b + c) = (a + b) + c"; in numbers, this means 2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.
