Answer:

a < c

Step-by-step explanation:

<u>Given inequality:</u>

a/b > c/b

<u>Since b is negative, when multiplied by b, the inequality changes to opposite direction:</u>

b(a/b) < b(c/b)
a < c

Answer:

Number 4: Using Pythagoras Theorem,

$\sqrt{30^2+40^2} =50$

Number 5:

$\sqrt{41^2-40^2}=9$

$\sqrt{11^2+60^2} =61$ It is a right triangle

$\sqrt{9^2+37^2} =38.09$ Not a right triangle

For the last one:

$\sqrt{(\sqrt{20^2+6^2})^2+6^2} =2\sqrt{118}$

Rounded down (because the answer needs to be a whole number) is 21

There is a 0.9968 probability that a randomly selected 50-year-old female lives through the year (based on data from the U.S. Department of Health and Human Services).

-------------------

A Fidelity life insurance company charges $226 for insuring that the female will live through the year. If she does not survive the year, the policy pays out $50,000 as a death benefit.

From the perspective of the 50-year-old female, what are the values corresponding to the two events of surviving the year and not surviving?

----

Ans: -226 ; 50,000-226 = 49774

-------------------------

If a 50-year-old female purchases the policy, what is her expected value?

WORK TRIED:

In the event she lives, the value is -$226. In the event she dies, the value is $49,774.

----

E(x) = 0.9968*(-226) + 0.0032(49774) = -$66

Plot the intercepts to graph the equation. x+y=3

andrey2020 [161]

Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Step-by-step explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3. Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3 Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.

Find the value of x in the triangle shown below.

nika2105 [10]

Answer:

$x = \sqrt{28}$

Step-by-step explanation:

Given,

Base of the triangle = 6

Hypotenuse of the triangle = 8

Let the height of the triangle = x

Therefore, According to Pythagoras Theorem,

${8}^{2} - {6}^{2} = {x}^{2}$

$= > 64 - 36 = {x}^{2}$

$= > 28 = {x}^{2}$

$= > x = \sqrt{28} (ans)$
