Answer:

Step-by-step explanation:
We require more information by I will explain in principle:
If Type A has at least 300 hours and Type B at least 400 hours.

You need to determine the Probability density function of X and Y and then subtract 1 from both

This will give you the probability of the expression.
Answer:
14 1/3
if you do 14 1/3 times two then add 8 u get 35
Answer:
16
Step-by-step explanation:
To solve plugin -3 for n

Then, solve using PEMDAS. First, do exponents

Next, add

So, 16 is the final answer.
Answer:
We are given a information that:
A school for learning foreign languages has 72 students who learn German, and 54 of those students also learn Russian. There are 12 students who do not learn German but learn Russian, and 10 students do not learn either German or Russian.
Based on this information we can make our table as:
Learn German don't learn German Total
LR 54 12 66
DNLR 18 10 28
Total 72 22 94
<em>DNLR represent do not learn Russian and LR represent learn Russian.</em>
Now for finding the conditional relative frequency table we divide each of the quantities by the total sum of each row i.e. first row is obtained by dividing by 66, second by dividing by 28 and third by dividing by 94 to obtain the table as:
Learn German don't learn German Total
LR 0.82 0.18 1
DNLR 0.64 0.36 1
Total 0.77 0.23 1
The slope of the red line that is perpendicular to the green line is: -5/2.
<h3>What are the Slope Values of Perpendicular Lines?</h3>
When one line lies perpendicular to another line, the slope of one must be the negative reciprocal of the other line.
<h3>What is the Negative Reciprocal of a Number?</h3>
If given a number, i.e. a/b, the negative reciprocal of a/b would the opposite value of the reciprocal of a/b.
Reciprocal of a/b is b/a. Negative reciprocal of a/b would therefore be: -b/a.
Given that the slope of the green line is: 2/5. And it is perpendicular to the red line. The slope of the red line would be the negative reciprocal of 2/5.
Negative reciprocal of 2/5 is -5/2.
Therefore, the slope of the red line is: -5/2.
