Answer:
Answers explained below
Step-by-step explanation:
(a) If there is high bias and high variability, the numbers will not be anywhere near the 42 percent value. If I wrote down 10 numbers and they were all completely different from 42, I would know that I have high bias and high variability.
(b) If a certain number of polls have just about the same average, but are nowhere near 42 percent, they have high bias and low variability. For example, 20 percent, but its far from 42 percent.
(c) If there is low bias and high variability, if you list the polls they will have an average around 42 percent. If you average the polls, you'll get 42 percent low bias. The high variability might be 20, 72% 42% 63% 10%
(d) If there is low bias and low variability, all of the polls will be close to 42 percent.
<u>Given:</u>
An isosceles trapezoid has a perimeter of 37 centimeters. Its shorter base measures 3 centimeters and its longer base measures 4 centimeters. The two remaining sides have the same length.
We need to determine the lengths.
<u>Length of the remaining sides:</u>
Let the length of the sides of the isosceles trapezoid be x.
Let a be the length of the shorter base.
Let b be the length of the longer base.
Thus, we have;

The formula to determine the length of the sides is given by

Substituting the values, we get;




Thus, the length of the sides of the isosceles trapezoid is 15 centimeters.

Answer:

Step-by-step explanation:
The given equation is :
d = 5x + 10xf
We need to solve the above equation for x.
Taking x common from RHS,
d=x(5+10f)
Dividing both sides by (5+10f),

Hence, this is the required value of x.
Answer:
0
Step-by-step explanation:
The total number of events is
45+37+52+94+72 = 300
P(purple) = purple/total
= 0/300
=0
