Answer:
Theoretical probability is a calculated value whereas experimental is an observed value. Theoretical is more reliable because it is usually not subject to all the testing failures that are possible. Experimental probability is only used in practice or when there isn't any theory.
Both are useful, but theoretical probability is more reliable because it has been studied and matured, so it is more foolproof than experiments.

Answer:
[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]
Step-by-step explanation:
1) Use difference of squares: a² - b² = (a + b) (a - b).
[tex]( {x}^{2} - {3}^{2} )(3x + 2)[/tex]
2) Simplify 3² to 9.
[tex]( {x}^{2} - 9)(3x + 2)[/tex]
3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.
[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]
Therefor, the answer is 3x³ + 2x² + -26x -18.

Solve the trigonometric equation for all values: -7 < or equal to x < 7 Question: Cot 1/2x-1=0
Answer:
x =90
Step-by-step explanation:
Cot 1/2x-1=0
Add 1 to both sides
Cot 1/2x = 0+1
Cot 1/2x = 1
1/tan1/2x = 1
Tan 1/2x = 1
1/2x = arctan1
1/2x =45
x = 45×2
x = 90
Hence the value of x is 90
While sorting some change into piggy banks, Gabby put 58 coins in the first piggy bank, 78 coins in the second piggy bank, 98 coins in the third piggy bank, and 118 coins in the fourth piggy bank. What kind of sequence is this?
arithmetic or geometric
Answer: Arithmetic (increasing by constant rate of 20)
Step-by-step explanation:
Arithmetic means the difference between two consecutive terms is constant which it is in this case because it constantly increases by a value of 20.
Geometric means the sequence is changing by a constant ratio or factor

again.
Answer:
40 seconds
Step-by-step explanation:
8 20
16 40
32

40 seconds
It will take 40seconds to both the lights to flash at the same time again.
What is Least common multiple?" Least common multiple is defined as the smallest common multiple of the given set of numbers."
According to the question,
Given ,
Time to flash Light A is every 8 seconds.
Time to flash Light B is every 20 seconds.
Condition given
Both the lights flash at the same time
Least common multiple (8, 20) = 40seconds
Light A flashes in
8seconds , 16seconds , 24seconds , 32seconds, 40seconds
Light B flashes in
20seconds , 40seconds
Hence, both the light flashes at the same time again is at 40seconds.

Which expression represents the algebraic phrase "eleven less than seven times a number"? 11x - 7 7 x minus 11 11 + 7x 11 minus 7 x
Answer:
7x minus 11
Step-by-step explanation:
7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)
Answer: (B) 7x minus 11

A farmer has a field in the shape of a semicircle of diameter 50 m. First,
calculate the length of the semicircle to 1 decimal place.
50 m
Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m
A survey of 1250 trees in a small wood showed that 32 percent were oak trees 26 percent were birch trees and the remainder were pine trees how many pine trees were there
Answer: There were 525 pine trees.
Step-by-step explanation:
Given: Total trees = 1250
Percentage of oak trees = 32%
Percentage of birch trees = 26%
Since remaining trees are pine trees.
Percentage of pine trees = 100% - 32% - 26%
=42%
The number of pine trees = 42% of 1250
= 0.42 ×1250
= 525
Hence, there were 525 pine trees.
