Answer:
The term that best describes a figure formed by three segments connecting three non-collinear points is:
Triangle.
Step-by-step explanation:
Step-by-step explanation:
We know that with the help of just one point we can't form any figure.
With the help of two points a line segment can be formed.
And with the help of three points if the three points are collinear a triangle can be formed.
Hence, the term that best describes a figure formed by three segments connecting three non-collinear points is:
Triangle.

5(4x+2+x)
=5(5x+2)
=C
=5(5x+2)
=25x+10
= D
Answer:
a) E(x)=3.565
b) c=3.8475 --> P(X < 3.8475) = 0.75
c) The probability that X falls above or below 0.28 min from the mean is P=0.4954.
Step-by-step explanation:
We have the cumulative distribution function as information.
a) To calculate the expected value, we can calculate the value of x in which F(x) equals 0.5. This happens for x=3.565.
b) What is the value c such that P(X < c) = 0.75?
In this case, we have to calculate x to have F(x)=0.75
This happens for x=3.8475.
c) We have to calculate the probability that X falls above or below 0.28 min from the mean (x=3.565).
This is the probability that the time is between 3.285 and 3.845
We can calculate this as:
The probability that X falls above or below 0.28 min from the mean is P=0.4954.

# siblings ratio fraction decimal percent
- 0 3 : 20 3/20 .15 15%
- 1 1 : 5 1/5 .20 20%
- 2 3 : 8 3/8 .375 37.5%
- 3 6 : 25 6/25 0.24 24%
- 4+ 7 : 200 7/200 0.035 3.5%
Step-by-step explanation:
I'll use row 3 as an example to show you how to do all these.
# siblings ratio fraction decimal percent
- 3 <u> </u> <u> </u> 0.24 <u> </u>
<u>To find fraction</u>
put number over 100 and just simplify as much as you can.
24/100 = 12/50 = 6/25
<u>To find ratio</u>
ratios are the same as fractions, but instead of the fraction bar or slash, you have a colon.
this one would look like 6 : 25 as a ratio.
<u>To find decimal</u>
DIVIDE the fraction or ratio (using a calculator if allowed, or by hand otherwise)
6/25 = 0.24
<u>To find percent</u>
take the decimal once you find it, and move the decimal point to the right by 2 digits. That's the percent.
0.24 ==> 24%
