Using probability we can calculate that the company must charge $697 for an expected return of 400 .
Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true. The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.
The probability that a 30 year old female lives throughout the year
= 0.99967
Death benefit = $900,000
Expected amount the company would pay = probability that a person dies × insurance amount.
Expected amount = (1 - 0.99967) × 900000 = $297
Now Company wants a profit of $400
Cost charged by company =$( 297 + 400 ) = $ 697
Therefore using probability we can calculate that the company must charge $697 for an expected return of $400 .

Answer:
A
Step-by-step explanation:
The multiplicative inverse property states that any number multiplied by its multiplicative inverse (also called reciprocal) results in 1.
Carlos is baking a pie with a circumference of 56 inches. What is the area of the pie he will bake?
the area of the pie that Carol will bake will be equal to 249.51 inches².
We are given the circumference of the pie as = 56 inches.
As pie is in the shape of a circle, we will use the formula for circumference to find the radius of the circle.
2 π r = 56 inches
2 × 22 / 7 × r = 56
r = 56 × 7 / ( 22 × 2)
r = 8.91 inches.
Area of circle is given by:
π r²
Substituting the values in the formula, we get that
A = 22 / 7 (8.91)²
A = 249.51 inches²
Therefore, we get that, the area of the pie that Carol will bake will be equal to 249.51 inches².

In the right-angled triangle ABC in Fig. 4.3, B = 90° and the lengths of AB and BC are given to the nearest centimetre. Calculate AC.
Answer:
|AC| = 132 cm (nearest centimetre)
Step-by-step explanation:
Pythagoras Theorem
Pythagoras Theorem explains the relationship between the three sides of a right triangle. The formula is:
[tex]\large\boxed{c^2=a^2+b^2}[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangle.From inspection of the given right triangle:
a = AB = 45 cmb = BC = 124 cmc = ACSubstitute the given values into the formula and solve for AC:
[tex]\begin{aligned}c^2 & = a^2+b^2 &\\\\\implies AC^2&=AB^2+BC^2\\ AC^2&=45^2+124^2\\ AC^2&=2025+15376 \\ AC^2&=17401\\\sqrt{ AC^2}&=\sqrt{ 17401}\\ AC&=131.91285\\AC&=132\; \sf cm \; (nearest\;centimetre)\end{aligned}[/tex]
Therefore, |AC| is 132 cm to the nearest centimetre.

Point C represents √11 on number line
Define number line.A number line is a visual depiction of numbers on a straight line in mathematics. A number line's numerals are arranged in a sequential manner at equal intervals along its length. It is often displayed horizontally and can extend indefinitely in any direction. A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart throughout its length. Since it's not a ruler, the distance between each number is irrelevant; instead, the numbers on the line specify how it should be used.

The x and y intercepts of the given graph of the function are 3/2 and -1 respectively.
Intercepts of the line
The point where the line or curve crosses the axis of the graph is called intercept. If a point crosses the x-axis, then it is called the x-intercept. If a point crosses the y-axis, then it is called the y-intercept.
Given equation of the line:
y = (2/3)x - 1
To find the y -intercept, putting x = 0, we get,
y = (2/3)*0 - 1
y = 0 - 1
y = -1
Hence, the y - intercept is -1.
To find the x -intercept, putting y = 0, we get,

If the cafeteria ordered 400 paper plates. They used 226 at breakfast. They bought 100 more. Then, they used some plates for lunch. Now there are 78 plates. The number of plates that was used at lunch is 196.
Number of plated usedGiven :
Paper plates ordered = 400 plates
Plates used for breakfast = 226
Additional plate bought = 100
Plate used for lunch = ?
Hence,
Let calculate the plate left after breakfast
Number of plates = Paper plates ordered - Plates used for breakfast
Number of plates = 400 plates - 226 plates
Number of plates = 174 plates
Now let determine the plates that were used for lunch
Pates used for lunch :
Pates used for lunch = (174 + 100) -78
Pates used for lunch = 274 -78
Pates used for lunch = 196 plates
