134 A financial analyst believes that if interest rates decrease in a given period then the

lawyer [7]

The probability that the market will go up and interest rate will go down during the period in question is 0.03.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the market will go up and interest rate will go down = 0.08 X 0.40 = 0.03

What is the mean and median of the lengths . 10,31,36,36,38,42,47,48,49,and 52

Olin [163]

Answer:

$Mean = 38.9$ $Median = 40$

Step-by-step explanation:

When you find mean, you must add all the numbers together then divide by the amount of numbers.

$10+31+36+36+38+42+47+48+49 + 52$

$==> 389$

There are 10 numbers.

$389 / 10$

$==> 38.9$

To find median, you have to either find the middle number or find the two numbers that makes it equal. Since this range set is even, we use the second option.

$(x + y ) / 2$

$38 + 42$

$==> 80$

Divide by 2

$80 / 2$

$==> 40$

Create the linear equation from the points (3,3) and (1,-5).

Kisachek [45]

Answer:

$-4x + y = -9\:or\:y = 4x - 9$

Step-by-step explanation:

First, find the rate of change [slope]:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-3 - 5}{-3 + 1} = \frac{-8}{-2} = 4$

Then, plug these coordinates into the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done much swiftly that way. It does not matter which ordered pair you choose::

−5 = 4 + b

$\displaystyle -9 = b \\ \\ y = 4x - 9$

If you want it in Standard Form:

y = 4x - 9

- 4x - 4x

_________

$\displaystyle -4x + y = -9$

_______________________________________________

3 = 4[3] + b

$\displaystyle -9 = b \\ \\ y = 4x - 9$

y = 4x - 9

- 4x - 4x

_________

$\displaystyle -4x + y = -9$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.
