Answer:
From a glance, -1.67 is the answer.
Step-by-step explanation:
You have a higher probability of losing money than gaining it due to the distribution of probability. Aka: there are more chances to lose than win. As a result, you are expected to lose money. Only -1.67 is the only negative option, which means that we dont even need to do real math since there's already only one choice.
Answer:




Step-by-step explanation:
Given:

Solving (a): P(x < 810)
To solve this, we make use of:

Because

So:



Hence:

Solving (b): P(x < 800)
To solve this, we make use of:

Because:

So:

Solving (c): P(x > 808.40)
Here, we make use of complement rule:

Where:



So:


Solving (d) The probability that the temperature lies outside 805.60 and 808.40
First, we calculate the probability that it lies within.
This is represented as:

This is calculated using:





Using complement rule, the required probability is:


Answer:
The slope of the line passing through the points (-4, 8) and (2,8) is 0
Step-by-step explanation:
The slope is 0 because you would subtract the y ones first 8-8, subtract the x ones next 2-(-4). You would get 0/6. When you would divide 0/6, you would get 0
Answer:
8
Step-by-step explanation:
every one text = 8 cents
as you should know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".
